    Healthy lifestyle interventions in general practice Part 13: Lifestyle and osteoporosis
    (South African Academy of Family Physicians, 2011) Schwellnus, M P; Patel, D N; Nossel, C; Dreyer, M; Whitesman, S; Micklesfield, L; Derman, E W
    Osteoporosis is defined as a systemic skeletal disease that is characterised by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fractures. Therefore, the diagnosis of osteoporosis is based on measurement of bone mineral density (BMD) using central (axial) dual energy X-ray absorptiometry (DXA), and clinical evidence of a fragility fracture (history or radiological evidence). Osteoporosis is a major public health problem, affecting about 30% of postmenopausal women of Caucasian origin, and 70% of those aged 80 years. The risk factors for osteoporosis include lifestyle factors, genetic/ethnic factors, specific diseases causing secondary osteoporosis, ageing factors, qualitative factors, and drugs that are toxic to bone. In addition, there are specific additional risk factors for falls that need to be considered. It is well established that lifestyle factors, including physical activity, nutritional intervention, psychosocial intervention, smoking cessation and other lifestyle factor interventions are key elements in the prevention and management of osteoporosis. Guidelines for these lifestyle interventions in the prevention and management of osteoporosis are reviewed.

    Healthy lifestyle interventions in general practice: Part 14: Lifestyle and obesity
    (South African Academy of Family Physicians, 2011) Derman, E W; Whitesman, S; Dreyer, M; Patel, D N; Nossel, C J; Lambert, E V; Schwellnus, M P
    Obesity is defined as an excessive amount of body fat or adiposity. It can be measured using the body mass index (BMI), and according to established criteria for adult men and women, overweight is defined as a BMI between 25-30 kg/m2, and obesity as a BMI > 30 kg/m2. Obesity is clinically associated with many serious co-morbidities, and is widely recognised as one of the leading health threats in most countries around the world. Weight loss is recommended for patients with a BMI > 25 kg/m2. The goals of weight loss therapy are to reduce obesity-related co-morbidities and decrease the risk of future obesity-related medical complications. The management of obesity is multifactorial, and involves the use of combined lifestyle interventions, including regular physical activity and dietary and psychosocial intervention. Practical clinical advice regarding interventions in these important areas is provided in this article.

    Healthy lifestyle interventions in general practice: Part 15: Lifestyle and lower back pain
    (South African Academy of Family Physicians, 2011) Schwellnus, M P; Patel, D N; Nossel, C; Whitesman, S; Derman, E W
    Lower back pain (LBP) is one of the most common medical problems in the adult population. LBP can be defined as pain, muscle tension or stiffness that is localised below the costal margin (inferior rib cage) and above the inferior gluteal folds and that can present either with or without leg pain (sciatica), and it can be classified as “specific” or “non-specific”. LBP has a high lifetime prevalence and is associated with a substantial direct and indirect cost to the individual and society. In this review, the focus is on the identification of lifestyle risk factors and interventions that are associated with mainly non-specific chronic LBP. In addition to pharmacotherapy, the best treatment approach is exercise therapy (including physical reconditioning), psychosocial and behavioural intervention and therapeutic education. Other lifestyle changes include nutritional intervention and smoking cessation.
