Anthropometric profile of the coloured population of the Cape Peninsula.
Study of a sample of 976 randomly selected coloured persons 15-64 years of age living in the Cape Peninsula included measurement of height, weight and mid-arm circumference and calculation of the body mass index (BMI). The mean height of the men was 167.6 cm and that of the women 156 cm. Mean weight, BMI and mid-arm circumference for men were 65.9 kg, 23.4 and 27.5 cm respectively and those for women 65.8 kg, 27.1 and 28.9 cm respectively. The prevalence of underweight for men (BMI less than 20) was 23.6% and for women (BMI less than 19) 9.8%; 17.7% of men were overweight (BMI greater than or equal to 25) and 3.7% obese (BMI greater than or equal to 30), while 35.2% of women were overweight (BMI greater than or equal to 24) and 18.8% obese. Overweight and obesity were more common among the older coloured women than among a group of South African white women of the same age. Obese women in the age group 35-44 years were 4.8 times more likely to be hypertensive than women of normal weight in the same age group (odds ratio; 95% confidence interval 2.2-4). Older women did not show this association. There were too few obese men to analyse in this manner. Many of the obese participants did not see themselves as obese. Only 19.7% of men and 45.2% of women had attempted to lose weight during the year preceding the study, in many cases using methods known to be ineffective. The coloureds of the Cape Peninsula were found to be a population with shorter stature than South African white and American populations. Some young participants of both sexes and some older men were underweight, while among older women there was a high prevalence of overweight and obesity. The findings may suggest previous undernutrition in both sexes, with a marked tendency to current overnutrition in adult females.
