Data from the Third National Health and Nutrition Examination Survey were used to assess relationships of diet and anthropometric measurements to serum HDL and LDL-cholesterol levels in adults. The sample consisted of 4,764 subjects (2,447 males and 2,317 females), ages 19-90 yrs. The participants were not taking medication for hyperlipidemia. Data were analyzed by SAS and SUDAAN using multiple regression analyses. All analyses incorporated sampling weights. For males, results showed that among dietary variables, percent kilocalories from carbohydrates and fat, polyunsaturated fatty acids, and dietary fiber were significantly related to serum HDL-cholesterol levels (p £ 0.05). Also, for males percent kilocalories from carbohydrates, protein, fat, and alcohol were also significantly related to serum LDL- cholesterol levels (p£0.05). For females, dietary fiber was the only dietary component that was significantly related to serum HDL-cholesterol levels (p £0.05). No significance was shown between diet and serum LDL-cholesterol levels for females. Among the male participants, waist-hip ratio (WHR) was significantly related to serum HDL and LDL-cholesterol levels (p £ 0.0001). Body mass index was also significantly related to serum HDL-cholesterol levels (p £0.01) in males. For females, multiple skinfold measurements (triceps, subscapula, suprailiac,and thigh) were significantly related to serum HDL and LDL-cholesterol levels (p £0.0001). Similarly,WHR was related significantly to serum HDL and LDL-cholesterol levels (p£ 0.0001) in females. WHR accounted for most of the variance in serum lipids for both males and females. These findings could have implications for cardiovascular risk factor assessment and reduction.
Learning Objectives: 1. Assess the relationship of diet to serum HDL and LDL-cholesterol levels. 2. Evaluate the associations between anthropometric measurements and serum HDL and LDL-cholesterol levels
