Acceptability, feasibility and impact of routine screening to detect undiagnosed HIV infection in 17 - 24-month-old children in the western sub-district of Cape Town
(2012) Levin, Michael; Mathema, Hlengani; Stinson, Kathryn; Jennings, Karen
OBJECTIVES: To explore the acceptability and feasibility of routine HIV screening in children at primary healthcare clinics and ascertain the prevalence of previously undiagnosed HIV infection in 17 - 24 month old children accessing curative and routine services. METHODS: A survey was conducted in 4 primary health clinics in the western sub-district of Cape Town. Rapid HIV screening of 17 - 24 month old children was performed for consenting caregiver-child pairs. Data on demographics, child health and antenatal history were collected using questionnaires. RESULTS: During recruitment, 358 children (72%) were tested for HIV infection. Most of the children (95.8%) were accompanied by a parent. The prevalence of reported HIV exposure among children was 21% (107/499). Of these, 3 had previously confirmed HIV infection; 1 was reportedly confirmed by a 6-week HIV test, and the other 2 probably contracted the virus via late post-partum transmission. The overall transmission rate was 3.5% (3/86) and the confirmed proportion of HIV-infected children was 0.8% (3/361). No previously unknown HIV infection was detected. CONCLUSIONS: Programmes to prevent mother-to-child transmission are effective, but at-risk infants who test negative at 6 weeks should be monitored for subsequent seroconversion. Parents of HIV-exposed infants are more likely to permit (re)testing of their infants than those whose offspring are not at risk. Routine HIV testing of children is feasible and acceptable at primary level, but may require additional resources to achieve universal coverage. Routine screening at an earlier age may detect previously undiagnosed HIV infection.

Accuracy of assessment of eligibility for early medical abortion by community health workers in Ethiopia, India and South Africa
(Public Library of Science, 2016) Johnston, Heidi Bart; Ganatra, Bela; Nguyen, My Huong; Habib, Ndema; Afework, Mesganaw Fantahun; Harries, Jane; Iyengar, Kirti; Moodley, Jennifer; Lema, Hailu Yeneneh; Constant, Deborah; Sen, Swapnaleen
Objective To assess the accuracy of assessment of eligibility for early medical abortion by community health workers using a simple checklist toolkit. Design Diagnostic accuracy study. Setting Ethiopia, India and South Africa. METHODS: Two hundred seventeen women in Ethiopia, 258 in India and 236 in South Africa were enrolled into the study. A checklist toolkit to determine eligibility for early medical abortion was validated by comparing results of clinician and community health worker assessment of eligibility using the checklist toolkit with the reference standard exam. RESULTS: Accuracy was over 90% and the negative likelihood ratio <0.1 at all three sites when used by clinician assessors. Positive likelihood ratios were 4.3 in Ethiopia, 5.8 in India and 6.3 in South Africa. When used by community health workers the overall accuracy of the toolkit was 92% in Ethiopia, 80% in India and 77% in South Africa negative likelihood ratios were 0.08 in Ethiopia, 0.25 in India and 0.22 in South Africa and positive likelihood ratios were 5.9 in Ethiopia and 2.0 in India and South Africa. CONCLUSION: The checklist toolkit, as used by clinicians, was excellent at ruling out participants who were not eligible, and moderately effective at ruling in participants who were eligible for medical abortion. Results were promising when used by community health workers particularly in Ethiopia where they had more prior experience with use of diagnostic aids and longer professional training. The checklist toolkit assessments resulted in some participants being wrongly assessed as eligible for medical abortion which is an area of concern. Further research is needed to streamline the components of the tool, explore optimal duration and content of training for community health workers, and test feasibility and acceptability.

Adherence in HIV-positive women entering antenatal care on antiretroviral therapy: A cross-sectional study
(2015) O'Sullivan, Briana Jean; Myer, Landon
Proper implementation of and adherence to antiretroviral therapy (ART) is significantly associated with better health and longer life in HIV-positive individuals. Consistent, adequate adherence has been shown to lead to a suppressed viral load. A low viral load delays the virus's progression and leads to better health outcomes for the individual. Adequate adherence is especially important among HIV-positive pregnant women. How well a woman adheres to her ART can not only improve her health during pregnancy but can protect the infant from HIV by preventing in utero transmission of the virus. Continuing ART protects against transmission via breastmilk later in the infant's life. While the benefits of good adherence are undeniable, the definition of adequate adherence varies widely in the literature. Taking 80 to 100% of pills as prescribed is commonly used as the threshold for adequate adherence levels. Various methods exist for measuring ART adherence, and while some are more reliable than others, there is no gold standard. This ambiguity in ART research extends to pregnant women, with even less known about HIV infected women established already on ART who then become pregnant. Changes in treatment protocols in the Western Cape and improvement of ART delivery throughout South Africa have resulted in this group of long-term users growing in size. Without more research into the barriers of ART adherence in these women, efforts to scale up treatment programs and to end mother to child transmission of HIV will ultimately fail. This dissertation is an exploration of these ideas. It begins to fill the gap in current knowledge related to ART compliance in pregnant women, and gives new insights into how specific barriers to adherence can adversely affect this specific group of established ART users.

Adolescent and young pregnant women at increased risk of mother-to-child transmission of HIV and poorer maternal and infant health outcomes: A cohort study at public facilities in the Nelson Mandela Bay Metropolitan district, Eastern Cape, South Africa
(2014) Fatti, Geoffrey; Shaikh, Najma; Eley, Brian; Jackson, Debra; Grimwood, Ashraf
BACKGROUND: South Africa (SA) has the highest burden of childhood HIV infection globally, and has high rates of adolescent and youth pregnancy OBJECTIVE: To explore risks associated with pregnancy in young HIV-infected women, we compared mother-to-child transmission (MTCT) of HIV and maternal and infant health outcomes according to maternal age categories METHODS: A cohort of HIV-positive pregnant women and their infants were followed up at three sentinel surveillance facilities in the Nelson Mandela Bay Metropolitan (NMBM) district, Eastern Cape Province, SA. Young women were defined as 24 years as the comparison group RESULTS: Of 956 mothers, 312 (32.6%) were young women; of these, 65 (20.8%) were adolescents. The proportion of young pregnant women increased by 24% between 2009/10 and 2011/12 (from 28.3% to 35.1%). Young women had an increased risk of being unaware of their HIV status when booking (adjusted risk ratio (aRR) 1.37; 95% confidence interval (CI) 1.21 - 1.54), a reduced rate of antenatal antiretroviral therapy (ART) uptake (adjusted hazard ratio 0.46; 95% CI 0.31 - 0.67), reduced early infant HIV diagnosis (aRR 0.94; 95% CI 0.94 - 0.94), and increased MTCT (aRR 3.07; 95% CI 1.18 - 7.96; adjusted for ART use). Of all vertical transmissions, 56% occurred among young women. Additionally, adolescents had increased risks of first presentation during labour (aRR 3.78; 95% CI 1.06 - 13.4); maternal mortality (aRR 35.1; 95% CI 2.89 - 426) and stillbirth (aRR 3.33; 95% CI 1.53 - 7.25 CONCLUSION: An increasing proportion of pregnant HIV-positive women in NMBM were young, and they had increased MTCT and poorer maternal and infant outcomes than older women. Interventions targeting young women are increasingly needed to reduce pregnancy, HIV infection and MTCT and improve maternal and infant outcomes if SA is to attain its Millennium Development Goals

Are women with history of pre-eclampsia starting a new pregnancy in good nutritional status in South Africa and Zimbabwe?
(BioMed Central, 2018-06-15) Cormick, Gabriela; Betrán, Ana P; Harbron, Janetta; Dannemann Purnat, Tina; Parker, Catherine; Hall, David; Seuc, Armando H; Roberts, James M; Belizán, José M; Hofmeyr, G J
Background Maternal nutritional status before and during pregnancy is an important contributor to pregnancy outcomes and early child health. The aim of this study was to describe the preconceptional nutritional status and dietary intake during pregnancy in high-risk women from South Africa and Zimbabwe. Methods This is a prospective observational study, nested to the CAP trial. Anthropometric measurements before and during pregnancy and dietary intake using 24-h recall during pregnancy were assessed. The Intake Distribution Estimation software (PC-SIDE) was used to evaluate nutrient intake adequacy taking the Estimated Average Requirement (EAR) as a cut-off point. Results Three hundred twelve women who had pre-eclampsia in their last pregnancy and delivered in hospitals from South Africa and Zimbabwe were assessed. 73.7 and 60.2% women in South Africa and Zimbabwe, respectively started their pregnancy with BMI above normal (BMI ≥ 25) whereas the prevalence of underweight was virtually non-existent. The majority of women had inadequate intakes of micronutrients. Considering food and beverage intake only, none of the micronutrients measured achieved the estimated average requirement. Around 60% of pregnant women reported taking folic acid or iron supplements in South Africa, but almost none did so in Zimbabwe. Conclusion We found a high prevalence of overweight and obesity and high micronutrient intake inadequacy in pregnant women who had the previous pregnancy complicated with pre-eclampsia. The obesity figures and micronutrient inadequacy are issues of concern that need to be addressed. Pregnant women have regular contacts with the health system; these opportunities could be used to improve diet and nutrition. Trial registration PACTR201105000267371 . Registered 06 December 2010.

Assisted reproductive technology in South Africa: first results generated from the South African register of assisted reproductive techniques
(2012) Dyer, Silke Juliane; Kruger, Thinus Frans
OBJECTIVE: We present the first report from the South African Register of Assisted Reproductive Techniques. METHODS: All assisted reproductive technology (ART) centres in South Africa were invited to join the register. Participant centres voluntarily submitted information from 2009 on the number of ART cycles, embryo transfers, clinical pregnancies, age of female partners or egg donors, and use of fertilisation techniques. Data were anonymised, pooled and analysed. RESULTS: The 12 participating units conducted a total of 4 512 oocyte aspirations and 3 872 embryo transfers in 2009, resulting in 1 303 clinical pregnancies. The clinical pregnancy rate (CPR) per aspiration and per embryo transfer was 28.9% and 33.6%, respectively. Fertilisation was achieved by intracytoplasmic sperm injection in two-thirds of cycles. In most cycles, 1 - 2 embryos or blastocysts were transferred. Female age was inversely related to pregnancy rate. CONCLUSION: The register achieved a high rate of participation. The reported number of ART cycles covers approximately 6% of the estimated ART demand in South Africa. The achieved CPRs compare favourably with those reported for other countries.

Association between food intake and obesity in pregnant women living with and without HIV in Cape Town, South Africa: a prospective cohort study
(2021-08-04) Madlala, Hlengiwe P.; Steyn, Nelia P.; Kalk, Emma; Davies, Mary-Anne; Nyemba, Dorothy; Malaba, Thokozile R.; Mehta, Ushma; Petro, Gregory; Boulle, Andrew; Myer, Landon
Background Although global nutrition/dietary transition resulting from industrialisation and urbanisation has been identified as a major contributor to widespread trends of obesity, there is limited data in pregnant women, including those living with HIV in South Africa. We examined food-based dietary intake in pregnant women with and without HIV at first antenatal care (ANC) visit, and associations with maternal overweight/obesity and gestational weight gain (GWG). Methods In an urban South African community, consecutive women living with (n = 479) and without (n = 510) HIV were enrolled and prospectively followed to delivery. Interviewer-administered non-quantitative food frequency questionnaire was used to assess dietary intake (starch, protein, dairy, fruits, vegetables, legumes, oils/fats) at enrolment. Associations with maternal body mass index (BMI) and GWG were examined using logistic regression models. Results Among women (median age 29 years, IQR 25–34), the prevalence of obesity (BMI ≥ 30 kg/m2) at first ANC was 43% and that of excessive GWG (per IOM guidelines) was 37% overall; HIV prevalence was 48%. In women without HIV, consumption of potato (any preparation) (aOR 1.98, 95% CI 1.02–3.84) and pumpkin/butternut (aOR 2.13, 95% CI 1.29–3.49) for 1–3 days a week increased the odds of overweight/obesity compared to not consuming any; milk in tea/coffee (aOR 6.04, 95% CI 1.37–26.50) increased the odds of excessive GWG. Consumption of eggs (any) (aOR 0.52, 95% CI 0.32–0.86) for 1–3 days a week reduced the odds of overweight/obesity while peanut and nuts consumption for 4–7 days a week reduced the odds (aOR 0.34, 95% CI 0.14–0.80) of excessive GWG. In women with HIV, consumption of milk/yoghurt/maas to drink/on cereals (aOR 0.35, 95% CI 0.18–0.68), tomato (raw/cooked) (aOR 0.50, 95% CI 0.30–0.84), green beans (aOR 0.41, 95% CI 0.20–0.86), mixed vegetables (aOR 0.49, 95% CI 0.29–0.84) and legumes e.g. baked beans, lentils (aOR 0.50, 95% CI 0.28–0.86) for 4–7 days a week reduced the odds of overweight/obesity; tomato (raw/cooked) (aOR 0.48, 95% CI 0.24–0.96) and mixed vegetables (aOR 0.38, 95% CI 0.18–0.78) also reduced the odds of excessive GWG. Conclusions Diet modification may promote healthy weight in pregnant women living with and without HIV.

"A Baby Was an Added Burden": Predictors and consequences of unintended pregnancies for female sex workers in Mombasa, Kenya: a mixed-methods study
(Public Library of Science, 2016) Luchters, Stanley; Bosire, Wilkister; Feng, Amy; Richter, Marlise L; King'ola, Nzioki; Ampt, Frances; Temmerman, Marleen; Chersich, Matthew F
Introduction Female sex workers (FSW) have high rates of unintended pregnancy, sexually transmitted infections including HIV, and other adverse sexual and reproductive health outcomes. Few services for FSWs include contraception. This mixed-methods study aimed to determine the rate, predictors and consequences of unintended pregnancy among FSWs in Mombasa, Kenya. METHODS: A prospective cohort study of non-pregnant FSWs was conducted. Quantitative data were collected quarterly, including a structured questionnaire and testing for pregnancy and HIV. Predictors of unintended pregnancy were investigated using multivariate logistic regression. Qualitative data were gathered through focus group discussions and in-depth interviews with FSWs who became pregnant during the study, and interviews with five key informants. These data were transcribed, translated and analysed thematically. RESULTS: Four hundred women were enrolled, with 92% remaining in the cohort after one year. Fifty-seven percent reported using a modern contraceptive method (including condoms when used consistently). Over one-third (36%) of women were using condoms inconsistently without another method. Twenty-four percent had an unintended pregnancy during the study. Younger age, having an emotional partner and using traditional or no contraception, or condoms only, were independent predictors of unintended pregnancy. Women attributed pregnancy to forgetting to use contraception and being pressured not to by clients and emotional partners, as well as "bad luck". They described numerous negative consequences of unintended pregnancy. CONCLUSION: Modern contraceptive uptake is surprisingly low in this at-risk population, which in turn has a high rate of unintended pregnancy. The latter may result in financial hardship, social stigma, risk of abandonment, or dangerous abortion practices. FSWs face considerable barriers to the adoption of dual method contraceptive use, including low levels of control in their emotional and commercial relationships. Reproductive health services need to be incorporated into programs for sexually transmitted infections and HIV, which address the socially-determined barriers to contraceptive use.

Can social protection improve Sustainable Development Goals for adolescent health?
(Public Library of Science, 2016) Cluver, Lucie D; Orkin, F Mark; Meinck, Franziska; Boyes, Mark E; Yakubovich, Alexa R; Sherr, Lorraine
BACKGROUND: The first policy action outlined in the Sustainable Development Goals (SDGs) is the implementation of national social protection systems. This study assesses whether social protection provision can impact 17 indicators of five key health-related SDG goals amongst adolescents in South Africa. METHODS: We conducted a longitudinal survey of adolescents (10-18 years) between 2009 and 2012. Census areas were randomly selected in two urban and two rural health districts in two South African provinces, including all homes with a resident adolescent. Household receipt of social protection in the form of 'cash' (economic provision) and 'care' (psychosocial support) social protection, and health-related indicators within five SDG goals were assessed. Gender-disaggregated analyses included multivariate logistic regression, testing for interactions between social protection and socio-demographic covariates, and marginal effects models. FINDINGS: Social protection was associated with significant adolescent risk reductions in 12 of 17 gender-disaggregated SDG indicators, spanning SDG 2 (hunger); SDG 3 (AIDS, tuberculosis, mental health and substance abuse); SDG 4 (educational access); SDG 5 (sexual exploitation, sexual and reproductive health); and SDG 16 (violence perpetration). For six of 17 indicators, combined cash plus care showed enhanced risk reduction effects. Two interactions showed that effects of care varied by poverty level for boys' hunger and girls' school dropout. For tuberculosis, and for boys' sexual exploitation and girls' mental health and violence perpetration, no effects were found and more targeted or creative means will be needed to reach adolescents on these challenging burdens. Interpretation National social protection systems are not a panacea, but findings suggest that they have multiple and synergistic positive associations with adolescent health outcomes. Such systems may help us rise to the challenges of health and sustainable development.

CareConekta: study protocol for a randomized controlled trial of a mobile health intervention to improve engagement in postpartum HIV care in South Africa
(2020-03-12) Clouse, Kate; Phillips, Tamsin K; Camlin, Carol; Noholoza, Sandisiwe; Mogoba, Phepo; Naidoo, Julian; Langford, Richard; Weiss, Martin; Seebregts, Christopher J; Myer, Landon
Abstract Background South Africa is home to the world’s largest antiretroviral therapy program but sustaining engagement along the HIV care continuum has proven challenging in the country and throughout the wider region. Population mobility is common in South Africa, but there are important research gaps in describing this mobility and its impact on engagement in HIV care. Postpartum women and their infants in South Africa are known to be at high risk of dropping out of HIV care after delivery and are frequently mobile. Methods In 2017, we developed a beta version of a smartphone application (app) - CareConekta - that detects a user’s smartphone location to allow for prospective characterization of mobility. Now we will adapt and test CareConekta to conduct essential formative work on mobility and evaluate an intervention - the CareConekta app plus text notifications and phone calls and/or WhatsApp messages - to facilitate engagement in HIV care during times of mobility. During the 3-year project period, our first objective is to evaluate the feasibility, acceptability, and initial efficacy of using CareConekta as an intervention to improve engagement in HIV care. Our second objective is to characterize mobility among South African women during the peripartum period and its impact on engagement in HIV care. We will enroll 200 eligible pregnant women living with HIV and receiving care at the Gugulethu Midwife Obstetric Unit in Cape Town, South Africa. Discussion This work will provide critical information about mobility during the peripartum period and the impact on engagement in HIV care. Simultaneously, we will pilot test an intervention to improve engagement with rigorously assessed outcomes. If successful, CareConekta offers tremendous potential as a research and service tool that can be adapted and evaluated in multiple geographic regions, study contexts, and patient populations.

Determining antenatal medicine exposures in South African women: a comparison of three methods of ascertainment
(2022-06-03) van der Hoven, Jani; Allen, Elizabeth; Cois, Annibale; de Waal, Renee; Maartens, Gary; Myer, Landon; Malaba, Thokozile; Madlala, Hlengiwe; Nyemba, Dorothy; Phelanyane, Florence; Boulle, Andrew; Mehta, Ushma; Kalk, Emma
Background In the absence of clinical trials, data on the safety of medicine exposures in pregnancy are dependent on observational studies conducted after the agent has been licensed for use. This requires an accurate history of antenatal medicine use to determine potential risks. Medication use is commonly determined by self-report, clinician records, and electronic pharmacy data; different data sources may be more informative for different types of medication and resources may differ by setting. We compared three methods to determine antenatal medicine use (self-report, clinician records and electronic pharmacy dispensing records [EDR]) in women attending antenatal care at a primary care facility in Cape Town, South Africa in a setting with high HIV prevalence. Methods Structured, interview-administered questionnaires recorded self-reported medicine use. Data were collected from clinician records and EDR on the same participants. We determined agreement between these data sources using Cohen’s kappa and, lacking a gold standard, used Latent Class Analysis to estimate sensitivity, specificity and positive predictive value (PPV) for each data source. Results Between 55% and 89% of 967 women had any medicine use documented depending on the data source (median number of medicines/participant = 5 [IQR 3–6]). Agreement between the datasets was poor regardless of class except for antiretroviral therapy (ART; kappa 0.6–0.71). Overall, agreement was better between the EDR and self-report than with either dataset and the clinician records. Sensitivity and PPV were higher for self-report and the EDR and were similar for the two. Self-report was the best source for over-the-counter, traditional and complementary medicines; clinician records for vaccines and supplements; and EDR for chronic medicines. Conclusions Medicine use in pregnancy was common and no single data source included all the medicines used. ART was the most consistently reported across all three datasets but otherwise agreement between them was poor and dependent on class. Using a single data collection method will under-estimate medicine use in pregnancy and the choice of data source should be guided by the class of the agents being investigated.

Dietary adequacy, variety and diversity and associated factors (anthropometry and socio-economic status) in pregnant women attending the Bishop Lavis MOU in Cape Town
(2015) De Bruyn, Celeste Marinda; Harbron, Janetta; Senekal, Marjanne; Odendaal, Hein J
Aim: The aim of this study was to determine the adequacy of the dietary intake of pregnant women attending Bishop Lavis MOU, in the Tygerberg area of Cape Town. Methods: One hundred and fifty-two women between 12 and 20 weeks' gestational age participating in the Main PASS study were recruited. They completed three interviewer-administered 24-hour dietary recall assessments on three different days, each approximately two weeks apart. Dietary reference values for adequate nutritional intake during pregnancy and the South African food based dietary guidelines and NARs and MAR were used to assess the nutritional adequacy. Anthropometric and socio-demographic information was also collected. Results: The results indicate that just over a quarter of the sample were classified as teenage pregnancies. The majority had between grades eight and ten, and had a monthly household income between R500 and R5000. With a mean energy intake of 10 168.4kJ, majority (79.5%) of the study sample did not meet the energy DRI. Close to half (42.8 %) of the study sample did not meet the DRI for protein intake. All participants met the carbohydrate EAR, and many exceeded the recommended fat intake. The intake of sugar and saturated fats exceeded recommendations with sugar contributing to almost half of the total energy from carbohydrates. The intakes of vitamin A, D and E, pantothenate, biotin, folate, calcium, iron, magnesium, potassium, and manganese fell below the recommendations. Sugar was the most commonly consumed food item, followed by potato, chicken, milk, and white bread. Apples were the most commonly consumed fruit. When compared to the FBDG, the study sample consumed double the recommended portions of starch, half the recommended daily fruit and vegetables, and half the recommended legumes. Conclusion: The high intake of refined carbohydrates, especially sugar, and the high intake of foods high in saturated fats needs to be addressed. Micronutrient intake is generally poor, especially with nutrients that are vital to proper growth and development of the foetus. Education on appropriate dietary changes, as well as suggestions to make implementation of such changes affordable would be invaluable, and may contribute towards decreasing the incidence of adverse pregnancy outcomes.

The differential expression of Kiss1, MMP9 and angiogenic regulators across the feto-maternal interface of healthy human pregnancies: implications for trophoblast invasion and vessel development
(Public Library of Science, 2013) Matjila, Mushi; Millar, Robert; van der Spuy, Zephne; Katz, Arieh
Genes involved in invasion of trophoblast cells and angiogenesis are crucial in determining pregnancy outcome. We therefore studied expression profiles of these genes in both fetal and maternal tissues to enhance our understanding of feto-maternal dialogue. We investigated the expression of genes involved in trophoblast invasion, namely Kiss1, Kiss1 Receptor (Kiss1R) and MMP9 as well as the expression of angiogenic ligands Vascular Endothelial Growth Factor-A ( VEGF-A) and Prokineticin-1 ( PROK1 ) and their respective receptors (VEGFR1, VEGFR2 and PROK1R ) across the feto-maternal interface of healthy human pregnancies. The placenta, placental bed and decidua parietalis were sampled at elective caesarean delivery. Real-time RT-PCR was used to investigate transcription, while immunohistochemistry and western blot analyses were utilized to study protein expression. We found that the expression of Kiss1 (p<0.001), Kiss1R (p<0.05) and MMP9 (p<0.01) were higher in the placenta compared to the placental bed and decidua parietalis. In contrast, the expression of VEGF-A was highest in the placental bed ( p<0.001 ). While VEGFR1 expression was highest in the placenta (p<0.01), the expression of VEGFR2 was highest in the placental bed (p<0.001). Lastly, both PROK1 (p<0.001) and its receptor PROK1R (p<0.001) had highest expression in the placenta. Genes associated with trophoblast invasion were highly expressed in the placenta which could suggest that the influence on invasion capacity may largely be exercised at the fetal level. Furthermore, our findings on angiogenic gene expression profiles suggest that angiogenesis may be regulated by two distinct pathways with the PROK1/PROK1R system specifically mediating angiogenesis in the fetus and VEGFA/VEGFR2 ligand-receptor pair predominantly mediating maternal angiogenesis.

Domestic and intimate partner violence among pregnant women in a low resource setting in South Africa: a facility-based, mixed methods study
(BioMed Central, 2018-07-04) Field, Sally; Onah, Michael; van Heyningen, Thandi; Honikman, Simone
Background Rates of violence against women are reported to be highest in Africa compared to other continents. We aimed to determine associations between mental illness, demographic, psychosocial and economic factors with experience of intimate partner violence (IPV) among pregnant women in a low resource setting in Cape Town and to explore the contextual elements pertaining to domestic violence. Methods We recruited adult women attending antenatal services at a primary-level maternity facility. Demographic, socioeconomic and psychosocial data were collected by questionnaire. The Expanded Mini- International Neuropsychiatric Interview (MINI) Version 5.0.0 was used to assess mental health status and the Revised Conflict Tactic Scale (CTS2) used to assess IPV in the six months prior to the study. Non-parametric tests, Wilcoxon sum of rank test, Fisher Exact and two sample T test and multicollinearity tests were performed. Descriptive, bivariate and logistic regression analyses were conducted to identify associations between the outcome of interest and key predictors. A probability value of p ≤ 0.05 was selected. From counselling case notes, a thematic content analysis was conducted to describe contextual factors pertaining to forms of domestic violence (DV). Results The prevalence of IPV was 15% of a sample of 376 women. Women who were food insecure, unemployed, in stable but unmarried relationships, had experienced any form of past abuse and were not pleased about the current pregnancy were more likely to experience IPV. MINI-defined mental health problems and a history of mental illness were significantly associated with IPV. Qualitative analysis of 95 counselling case notes revealed that DV within the household was not limited to intimate partners and, DV in this context was often perceived as ‘normal’ behaviour by the participants. Conclusions This study contributes towards a greater understanding of the risk profile for IPV amongst pregnant women in low-income settings. Adversity, including food insecurity and mental ill-health are closely associated with IPV during the antenatal period. Advocates against violence against pregnant women are advised to consider that violence in the home may be perpetrated by non-intimate partners and may by enabled by a pervasive belief in the acceptability of the violence.

Evaluating viral load monitoring in antiretroviral-experienced HIV-positive pregnant women accessing antenatal care in Khayelitsha, Cape Town
(2015) Cragg, Carol Diane; Stinson, Kathryn; Giddy, Janet
BACKGROUND: A viral load monitoring algorithm in the 2013 Western Cape Department of Health PMTCT guidelines include VL measurement in women who are antiretroviral (ART)-experienced at presentation for antenatal care, the timing of subsequent VL measurements and criteria for regimen change. The study evaluates the implementation of the algorithm in women who are virologically nonsuppressed and determines the outcomes of virological resuppression and infant PCR status. METHODS: This retrospective cohort study focused on all ART-experienced women who presented for antenatal care at one of two primary level Maternity Obstetric Units (MOUs) in Khayelitsha, Cape Town between July 2013 and June 2014. The study used routine data from facility registers, clinical records and electronic monitoring systems at the MOU, and referral ART sites and hospitals. Data collected included age, ART clinic, start date and regimen, and maternal VL and infant PCR results. RESULTS: Forty percent of the 1412 HIV-positive pregnant women, were ART-experienced, of whom 14.1 % were VNS. Predictors of being VNS included a duration on ART of more than 4 years (p= 0.04), attending an ART clinic other than that in the facility (p= 0.02), being on a second-line ART regimen (p=0.07) and being younger than 25 years (p= 0.05). The algorithm was correctly followed in up to 87.5% of women identified as VNS. The rate of virological resuppression by three months postpartum was 70.0% to 82.3%. Excluding three neonates who died, all of the 82.2% of infants tested were PCR negative. CONCLUSIONS: Nearly 15% of ART-experienced women were virologically nonsuppressed on presentation for antenatal care. Levels of adherence to the guideline, and virological resuppression rates of up to 82.3% are encouraging. The implementation of the VLM algorithm could be improved by the integration of obstetric and ART care, the adoption of a single electronic monitoring system and the use of standardised integrated clinical stationery.

Evaluation of a nutrition supplementation programme in the Northern Cape Province of South Africa
(2003) Hendricks, MK; le Roux, M; Fernandes, M; Irlam, J
AIM: This study aimed at assessing the effectiveness regarding implementation and impact of a take-home nutrition supplementation programme, the Protein Energy Malnutrition (PEM) Scheme, that targets malnourished pre-school children and pregnant and lactating women in the Northern Cape Province of South Africa. METHODOLOGY: In assessing implementation of the PEM Scheme, a cross-sectional descriptive study was undertaken over a 6-month period in the six regions of the Northern Cape Province. Interviews were conducted with programme managers and health personnel at clinics who were responsible for implementing the PEM Scheme. In assessing the impact of the PEM Scheme on growth, a retrospective review was done of the clinic records (including anthropometric data) of children enrolled in the PEM Scheme over a 1-year period. RESULTS: About 76% of the budget allocated to the PEM Scheme had been utilised over the 1-year period. The budget for the following financial year was based solely on food supplements purchased in the previous year. Coverage of malnourished pre-school children and eligible pregnant and lactating women for enrolment was estimated to be 50% and 60%, respectively. Eighty-five per cent of health facilities in the province participated in the PEM Scheme. Some of the main problems identified included: lack of training, inappropriate targeting of certain groups, incorrect application especially of discharge criteria for pregnant and lactating women, inadequate assessment for nutrition-related disease, inadequate nutrition counselling and no standardised monitoring. Of the 319 children enrolled over a year, the mean age was 16.2 (standard deviation 16.2) months, 41% had been low-birth-weight and 18% had been diagnosed with tuberculosis. Ten per cent of the children with a weight-for-age Z-score of <-2 moved into the normal Z-score range after being on the PEM Scheme for a mean duration of 8 months. There was an overall improvement in the weight-for-age Z-scores of 25% of the sample, with a significant difference between the mean weight-for-age Z-scores at enrolment and follow-up This was mainly related to significant improvement in the mean weight-for-age Z-scores of children <2 years. CONCLUSIONS: Numerous problems with the PEM Scheme have been identified which could have limited its impact. Recommendations are proposed for improving the effectiveness and impact of the PEM Scheme in the province.

Full-term, peri-urban South African infants under 6 months of age are at risk for early-onset anaemia
(2004) Sibeko, L N; Dhansay, M A; Charlton, K E; Johns, T; Van Stuijvenberg, M E; Gray-Donald, K
OBJECTIVE: There is a paucity of data on the micronutrient status of low-income, lactating South African women and their infants under 6 months of age. The aim of this study was to elucidate the level of anaemia and vitamin A deficiency (VAD) in peri-urban breast-feeding women and their young infants. DESIGN: Cross-sectional study including anthropometric, biochemical and infant feeding data. SETTING: Peri-urban settlement in Cape Town, South Africa. SUBJECTS: Breast-feeding women (n=113) and their infants (aged 1-6 months) attending a peri-urban clinic. RESULTS: Mean (standard deviation (SD)) haemoglobin (Hb) of the lactating mothers was 12.4 (1.3) g dl(-1), with 32% found to be anaemic (Hb<12 g dl(-1)). Maternal serum retinol was 49.8 (SD 13.3) microg dl(-1), with 4.5% VAD. Using breast milk, mean (SD) retinol concentration was found to be 70.6 (24.6) microg dl(-1) and 15.7 (8.3) microg/g milk fat, with 13% below the cut-off level of <8 microg/g fat. There was no correlation found between breast milk retinol and infant serum retinol. Z-scores (SD) of height-for-age, weight-for-age and weight-for-height were -0.69 (0.81), 0.89 (1.01) and 1.78 (0.83), respectively. Mean (SD) infant Hb was 10.9 (1.1) g dl(-1), with the prevalence of anaemia being 50%, 33% and 12% using Hb cut-offs below 11 g dl(-1), 10.5 g dl(-1) and 9.5 g dl(-1), respectively. Mean (SD) infant serum retinol was 26.9 (7.2) microg dl(-1), with 10% being VAD. None of the infants was exclusively breast-fed, 22% were predominantly breast-fed and 78% received complementary (mixed) breast-feeding. Thirty-two per cent of infants received weaning foods at an exceptionally young age (< or =1 month old). CONCLUSION: A high rate of anaemia is present in lactating women residing in resource-poor settings. Moreover, their seemingly healthy infants under 6 months of age are at an elevated risk of developing early-onset anaemia and at lower risk of VAD.

The global epidemiology of syphilis in the past century - a systematic review based on antenatal syphilis prevalence
(Public Library of Science, 2016) Kenyon, Chris Richard; Osbak, Kara; Tsoumanis, Achilleas
Author Summary: Syphilis rates have varied tremendously between different populations around the world. We conducted a systematic review of syphilis prevalence in pregnant women in 13 populations with available data for the last 100 years. Our findings were that in most populations syphilis prevalence dropped to under 1% before 1960. In the 2 populations from sub Saharan Africa, the syphilis prevalence remained around 6% until 50 years after the introduction of penicillin. Other systematic reviews were utilized to provide syphilis prevalence estimates for all countries with available data for the periods 1990-1999 and 2008. We assessed if there was a correlation between national syphilis prevalence in these periods and five explanatory factors. Only residence in sub-Saharan Africa was associated with syphilis prevalence in both time periods. These findings, considered in conjunction with other types of evidence we review, such as the strong correlations at population level between syphilis prevalence and those of Herpes Simplex Virus-2 prevalence and HIV prevalence, suggest that common risk factors may underpin the spread of all three of these sexually transmitted diseases. Establishing what these factors are is of great importance to improve the health of highly affected populations such as those in sub-Saharan Africa.

Growing inequities in maternal health in South Africa: a comparison of serial national household surveys
(2016) Wabiri, Njeri; Chersich, Matthew; Shisana, Olive; Blaauw, Duane; Rees, Helen; Dwane, Ntabozuko
Abstract Background Rates of maternal mortality and morbidity vary markedly, both between and within countries. Documenting these variations, in a very unequal society like South Africa, provides useful information to direct initiatives to improve services. The study describes inequalities over time in access to maternal health services in South Africa, and identifies differences in maternal health outcomes between population groups and across geographical areas. Methods Data were analysed from serial population-level household surveys that applied multistage-stratified sampling. Access to maternal health services and health outcomes in 2008 (n = 1121) were compared with those in 2012 (n = 1648). Differences between socio-economic quartiles were quantified using the relative (RII) and slope (SII) index of inequality, based on survey weights. Results High levels of inequalities were noted in most measures of service access in both 2008 and 2012. Inequalities between socio-economic quartiles worsened over time in antenatal clinic attendance, with overall coverage falling from 97.0 to 90.2 %. Nationally, skilled birth attendance remained about 95 %, with persistent high inequalities (SII = 0.11, RII = 1.12 in 2012). In 2012, having a doctor present at childbirth was higher than in 2008 (34.4 % versus 27.8 %), but inequalities worsened. Countrywide, levels of planned pregnancy declined from 44.6 % in 2008 to 34.7 % in 2012. The RII and SII rose over this period and in 2012, only 22.4 % of the poorest quartile had a planned pregnancy. HIV testing increased substantially by 2012, though remains low in groups with a high HIV prevalence, such as women in rural formal areas, and from Gauteng and Mpumalanga provinces. Marked deficiencies in service access were noted in the Eastern Cape ad North West provinces. Conclusions Though some population-level improvements occurred in access to services, inequalities generally worsened. Low levels of planned pregnancy, antenatal clinic access and having a doctor present at childbirth among poor women are of most concern. Policy makers should carefully balance efforts to increase service access nationally, against the need for programs targeting underserved populations.
