Serum high-density lipoprotein cholesterol, glucose tolerance and other variables in obese black adolescent girls.

Obesity is very common in South Africal Black girls aged 18 - 20 years. Severely obese White women have greatly reduced values for serum high-density lipoprotein (HDL) cholesterol. In a series of Black girls studied in rural and urban areas, mean values for HDL cholesterol were not significantly different in the obese compared with the non-obese groups. There were also no significant differences between obese and non-obese groups in mean serum cholesterol, triglyceride, uric acid, and blood glucose at fasting and 1 hour after a glucose drink. The same finding prevailed regarding blood pressures. All values for blood components were biologically more favourable in Black than in White adolescent girls (reported values). Mean sugar intakes of the obese were not significantly lower. Evidently, the metabolic and other disabilities linked with obesity in young White women have no counterpart in obese Black adolescent girls.
