The results were: cholesterol 166.7 +/- 30.9 mg/ml, triglyceride 81.1 +/- 42.3 mg/dl, HDL-cholesterol (HDLc) 57.4 +/- 11.6 mg/dl, HDL2c 20.6 +/- 9.8 mg/dl and HDL3c 37.1 +/- 7.8 mg/dl. Dietary surveys were carried out in 512 of these subjects and their average daily nutrient intake was estimated to be: total calories 2,577 Kcal, proteins 656 g (50.7 g of vegetable proteins), fat 69.1 g (P/S ratio 0.70), carbohydrates 423 g, cholesterol 282 mg, dietary fibres 23.5 g, sodium 4993 mg, potassium 2,618 mg and magnesium 575 mg. The serum lipid levels of urban and rural inhabitants were compared. Total cholesterol levels were significantly higher in urban inhabitants of all age groups and of both sexes, while triglyceride levels were significantly higher in urban inhabitants of certain age groups. However, HDLc levels, particularly HDL2c levels were significantly higher in rural inhabitants of most age groups and of both sexes. The above differences were probably the result of differences in dietary patterns and nutrient intake between urban and rural inhabitants. | lld:pubmed |
