Obesity in women from developing countries is a growing phenomenon, even though the rate is still relatively low in certain areas, namely South Asia (0.1%), sub-Saharan Africa (2.5%), and the Caribbean and Latin America (9.6%). In North Africa and the Middle East the prevalence of obesity is already 17.2%, not much lower than the 20.7% found in the USA. Thirty-six per cent of urban black women and 25% of rural black women in South Africa are obese.
'Big is beautiful' - an exploration with urban black community health workers in a South African townshipSource: South African Journal of Clinical Nutrition 18, pp 6 –15 (2005)More Less
Objectives. To explore perceptions about factors associated with body weight and body image among black female community health workers (CHWs) living and working in Khayelitsha, Cape Town.
Design. A descriptive, cross-sectional study.
Setting. Khayelitsha, a black township in Cape Town, South Africa.
Subjects. Forty-four black, female, Xhosa-speaking CHWs working in Khayelitsha.
Outcome measures. Anthropometric measures (height, weight, and waist circumference) were taken. Body mass index (BMI) was computed as a measure to estimate total body fat. Waist circumference was used as a measure of abdominal obesity. Focus groups were employed to explore beliefs and attitudes about body size. Information from the focus group discussions was used to develop a semi-structured questionnaire for individual interviews, which were conducted to validate the data from the focus groups, and to assess knowledge on causes and risk factors associated with obesity. A body satisfaction question was also included in the questionnaire. Body image was measured using body shape drawings (pictograms).
Results. Of the 44 women measured, 2 had normal weight (BMI 18.5 - 24.9 kg/m2), 2 were overweight (BMI 25 - 30 kg/m2), 25 were obese (BMI 30 - 40 kg/m2) and 15 were extremely obese (BMI ≥ ( 40 kg/m2). A moderately overweight shape (BMI 27 kg/m2) was preferred; this was associated with dignity, respect, confidence, beauty and wealth. Perceived causes of obesity were eating the wrong food, skipping breakfast and worries about debts, husbands/partners and teenage children. Negative aspects of obesity included body aches and tiredness.
Conclusion. This study emphasises the prevalence of obesity among urban black women in South Africa, particularly among CHWs. Socio-cultural, behavioural and environmental factors seem to influence the development of obesity in this population.

Objective. To examine the regularity of dietary supplement use and related information in a sample of 400 university students.
Design and outcome measures. An interview schedule was developed for these purposes containing questions on demographic and health and lifestyle-associated variables, regularity of supplement use, reasons for non-use or sporadic use and regular supplement use-related questions.
Setting. Stellenbosch University, South Africa.
Subjects. Four hundred undergraduate and postgraduate students.
Results. Non-use of supplements was reported by 38.5% of students. The main reason given for not using supplements at all was 'not necessary' and 'don't know/no reason'. Sporadic supplement use was reported by 19.5%, with the main reason for sporadic supplement use being 'use when stressed' and 'use when tired/ill'. Regular supplement use was reported by 42% of the students interviewed, with vitamin-mineral combination supplements being the most commonly used supplements. Regular supplement users showed no specific demographic or health and lifestyle-associated characteristics. Reasons provided by the regular supplement users were similar for most supplement types and seem to reflect the advertising strategies used by producers of supplements. The main reasons cited in this regard were 'physical health', 'dietary reasons' and 'body conditioning and energy'. Family and friends, doctors and advertising were the main sources of information on the need for supplementation. Students chose to use supplements instead of food because of perceived dietary inadequacy, convenience and the belief that food does not contain sufficient nutrients. Significant gender differences were found with regard to reasons for sporadic use of supplements, reasons for regular use of two specific supplements and reasons why a supplement was chosen instead of food in the case of a specific supplement.
Conclusion. Supplement use was found to be common practice in this student population, as has been found among students elsewhere.

Objective. To determine the habitual diet and the consumption of indigenous foods among college students in Limpopo province.
Design. The sample consisted of 37 healthy student volunteers (18 males and 19 females) aged 23.3 ± 2.38 years, with a body mass index of 22.7 ± 2.32 kg/2. A validated quantitative food frequency questionnaire was used to collect information on the habitual diet of the participants. Nutrient analysis was done using FoodFinder.
Results. Mean dietary intakes were 10 042 kJ, 16.3% protein energy, 28.9% fat energy and 54.8% carbohydrate energy for females, and 12 050 kJ, 16.7% protein energy, 26.4% fat energy and 56.9% carbohydrate energy for males. The contribution of fat, carbohydrate and protein to total energy intake was similar for males and females. Frequency of food item consumption varied among students with indigenous foods consumed less often. Consumption of indigenous foods was similar in male and female subjects.
Conclusion. The habitual diet of the college students was estimated, and compared favourably with other reported data. However, patterns of indigenous food consumption were difficult to estimate. Although the number of indigenous foods used was high at 28 of 60 food items, consumption in terms of both quantity and the total number of students consuming these foods was low. Further studies are needed to determine the patterns of indigenous food intake and the contribution of these foods to total nutrient intake.

The organisers of the 20th Biennial Congress of the Nutrition Society of South Africa (NSSA) and the 8th Biennial Congress of the Association for Dietetics in South Africa (ADSA), alias Nutrition Congress 2004 and held on 23 - 27 August 2004 at the Goudini Spa Holiday Resort, Worcester, were confident that the congress would be a success. However, both the number of delegates and the standard of the oral and poster presentations exceeded all expectations.
