    Parent perceptions of screen time use in young children with Autism Spectrum Disorder
    (2022) Ebrahim, Faatima Omarjee; Gretschel, Pamela; Abbas, Iesrafeel
    Screen time (ST) relates to accessing and engaging with electronic media, technology and devices that involves any type of screen. The global advancement and increasing availability of technology, together with the impact of COVID-19 pandemic restrictions on social engagement, appears to have led to a growing presence of ST in the lives of young children with autism spectrum disorder (ASD). Excessive ST has been associated with developmental delays, sleep disturbances, reduced physical activity and other health problems which can have significant negative impacts on the occupational engagement of children with ASD. Despite these concerns, little to no research focussing on ST use by children with ASD, nor of its impacts on their engagement in other occupations, has been conducted in middle-income countries, like South Africa. A qualitative descriptive design, using semi-structured, in-depth interviews with seven purposively selected participants in line with maximum variation, was used to explore and describe parents' perceptions of ST of their children with ASD. The study aimed to promote a better understanding of how and why their children used ST, what the effect of ST was on their children's lives, what strategies their parents used to mediate ST and the impact that the COVID19 pandemic had on ST use. The information gained will be used to inform intervention guidelines for the management of ST and for optimising its use, for children with ASD. Through a process of thematic analysis, four themes emerged from the data. The theme Seeking out ST opportunities described how children used ST in keeping with their interests and how their limited interest in non-ST activities made them seek opportunities for ST. Theme two, ST, a mixed blessing confirmed how parents viewed ST to have both benefits and drawbacks for their children and described how they tried to come to terms with ST as it created opposing effects in their children's lives. Theme three Striving to provide conditional access to ST found that these parents used a variety of restrictive mediation strategies to manage their child's ST, whilst trying to avoid the stress caused by limiting ST and allowing for its use under certain conditions. The fourth theme COVID-19 “intensified the whole screen time business” highlighted how ST became an appealing replacement during the pandemic adding new challenges that parents experienced with managing its use. Overall, these findings acknowledged the challenges and positive contributions that parents of children with ASD experienced because of ST of their children, which were exacerbated during the COVID-19 pandemic. This study supports the need for early childhood interventionists to consider ST as a significant occupation of children with ASD, that requires attention.

    Proportion of children meeting recommendations for 24-hour movement guidelines and associations with adiposity in a 12-country study
    (2016) Roman-Viñas, Blanca; Chaput, Jean-Philippe; Katzmarzyk, Peter T; Fogelholm, Mikael; Lambert, Estelle V; Maher, Carol; Maia, José; Olds, Timothy; Onywera, Vincent; Sarmiento, Olga L; Standage, Martyn; Tudor-Locke, Catrine; Tremblay, Mark S
    Abstract Background The Canadian 24-h movement guidelines were developed with the hope of improving health and future health outcomes in children and youth. The purpose of this study was to evaluate adherence to the 3 recommendations most strongly associated with health outcomes in new 24-h movement guidelines and their relationship with adiposity (obesity and body mass index z-score) across countries participating in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE). Methods Cross-sectional results were based on 6128 children aged 9–11 years from the 12 countries of ISCOLE. Sleep duration and moderate-to-vigorous physical activity (MVPA) were assessed using accelerometry. Screen time was measured through self-report. Body weight and height were measured. Body mass index (BMI, kg · m −2 ) was calculated, and BMI z-scores were computed using age- and sex-specific reference data from the World Health Organization. Obesity was defined as a BMI z-score > +2 SD. Meeting the overall 24-h movement guidelines was defined as: 9 to 11 h/night of sleep, ≤2 h/day of screen time, and at least 60 min/day of MVPA. Age, sex, highest parental education and unhealthy diet pattern score were included as covariates in statistical models. Associations between meeting vs. not meeting each single recommendation (and combinations) with obesity were assessed with odds ratios calculated using generalized linear mixed models. A linear mixed model was used to examine the differences in BMI z-scores between children meeting vs. not meeting the different combinations of recommendations. Results The global prevalence of children meeting the overall recommendations (all three behaviors) was 7%, with children from Australia and Canada showing the highest adherence (15%). Children meeting the three recommendations had lower odds ratios for obesity compared to those meeting none of the recommendations (OR = 0.28, 95% CI 0.18–0.45). Compared to not meeting the 24-h movement recommendations either independently or combined, meeting them was significantly associated with a lower BMI z-score. Whenever the MVPA recommendation was included in the analysis the odds ratios for obesity were lower. Conclusions For ISCOLE participants meeting these 3 healthy movement recommendations the odds ratios of being obese or having high BMI z-scores were lower. However, only a small percentage of children met all recommendations. Future efforts should aim to find promising ways to increase daily physical activity, reduce screen time, and ensure an adequate night’s sleep in children. Trial registration The International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) was registered at ClinicalTrials.gov (Identifier NCT01722500) (October 29, 2012).
