TL;DR
Differences in diet may explain this findings since the protein and fat intake was higher in group A than in group B and fat from animal sources predominated in Group A (72%) as compared to B (28%).
Abstract
We studied plasma lipoproteins in 2 groups of 50 women each, one with a high (A) and the other low socio-economic status (B). Age, caloric intake, energy output and weight for height relation were comparable in both groups. A significant difference was found in plasma levels of triglycerides (A = 138.9 vs B = 104.8 mg/dl), total cholesterol (A = 226.9, B = 178.8 mg/dl) and HDL cholesterol (A = 43.9, B = 50.7 mg/dl). Differences in diet may explain this findings since the protein and fat intake was higher in group A than in group B and fat from animal sources predominated in group A (72%) as compared to B (28%). No significant difference was found in the relation of polyunsaturated to saturated fatty acids in both groups.
