Association of dyslipidemia with intakes of fruit and vegetables and the body fat content of adults clinically selected for a lifestyle modification program.

摘要

The relationships between dyslipidaemia, body fat distribution and dietary intakes were studied in a population of adults clinically selected for a lifestyle modification programme (979 subjects (409 males and 570 females, 52.2 +or- 9.6 yr)). Overnight-fasting plasma was assayed for triglycerides (TG), total cholesterol (TC) and HDL cholesterol, and the non-HDL (n-HDL) fraction determined by the difference. Anthropometric assessment included body mass index (BMI), fat (bioelectrical impedance) and waist circumference (WC). Food intake was assessed by the 24-h recall questionnaire, and food groups evaluated through recommendations from an adapted food pyramid. The chances of dyslipidaemia from other variable changes were determined by logistic regression with P < 0.05. Normal values of BMI and WC were protective against all markers of dyslipidaemia whereas only hypercholesterolaemia was influenced by diet (meat intake >2 servings). Protection against hypertriglyceridaemia was afforded by dietary intakes of wholegrains (odds ratio (OR) 0.342 (CI 95%, 0.154-0.760)), >3 servings of fruits (OR 0.523, 0.290-0.941) and >4 servings of vegetables (OR 0.360, 0.176-0.735). In general, total body and abdominal adiposity influenced all dyslipidaemia markers while dietary intake of fruits and vegetables protected against triglyceridaemia.
