The East Baltimore study: the relationship of lipids and lipoproteins to selected cardiovascular risk factors in an inner city Black adult population

NZ Haigh, KM Salz, GA Chase, JA Jenkins, PS Bachorik and PO Kwiterovich Jr

Low socioeconomic status, inner city Black adults, aged 20 to 49 yr (24 males and 45 females), were randomly selected from East Baltimore, MD to study plasma lipid and lipoprotein levels. Several factors known to affect these levels also were examined: dietary intake, alcohol intake, degree of obesity (measured by body mass index), physical activity level, smoking, and hormone use. Compared to women, the men consumed 9.3 more calories/kg body weight (p less than 0.005), 273 mg more cholesterol/day (p less than 0.005), and 7% fewer calories as sucrose (p less than 0.01). The P/S ratio of both their diets was 0.5. The men also had a lower body mass index than the women (23.9 kg/m2 versus 29.0; p less than 0.001). Mean lipid and lipoprotein levels were similar in the men and women. However, the men's total cholesterol (167 mg/dl) and low density lipoprotein cholesterol (94 mg/dl) levels were lower than those of adult Blacks in other studies, while the levels of the East Baltimore women were similar to those in other studies. For women, body mass index and high density lipoprotein cholesterol were negatively correlated (p less than 0.01); triglycerides and oral contraceptive use were positively correlated (p less than 0.01). None of the factors studied explained the relatively low total cholesterol and low density lipoprotein cholesterol levels in these inner city Black adult men.
