Dietary intakes and blood lipid concentrations were assessed in elderly men (n = 65) and women (n = 92) from 1980 through 1989. Mean age in 1980 was 70 y (range 60-84 y). Health and socioeconomic status was above that found in the general US elderly population. Cross-sectional and longitudinal changes in variables were determined by using least-squares linear regression. No significant cross-sectional differences in energy (kJ/kg), protein (g/kg), total fat, and carbohydrate intake with age was noted. Significant longitudinal decreases in total fat, saturated and polyunsaturated fatty acids, and cholesterol intakes were noted in both men and women. Significant decreases in total, HDL, and LDL plasma cholesterol concentrations were noted over time in both men and women. Ratios of both total and LDL cholesterol to HDL cholesterol increased over time. The decrease in total fat and cholesterol intakes were significantly correlated with the decrease in total plasma cholesterol.
1980年至1989年期间，对65名老年男性和92名老年女性的饮食摄入量和血脂浓度进行了评估。1980年的平均年龄为70岁（范围60 - 84岁）。健康和社会经济状况高于美国老年人群体的平均水平。变量的横断面和纵向变化通过最小二乘线性回归确定。未发现能量（千焦/千克）、蛋白质（克/千克）、总脂肪和碳水化合物摄入量随年龄有显著的横断面差异。男性和女性的总脂肪、饱和脂肪酸和多不饱和脂肪酸以及胆固醇摄入量均有显著的纵向下降。男性和女性的血浆总胆固醇、高密度脂蛋白胆固醇和低密度脂蛋白胆固醇浓度均随时间显著下降。总胆固醇和低密度脂蛋白胆固醇与高密度脂蛋白胆固醇的比值随时间增加。总脂肪和胆固醇摄入量的下降与血浆总胆固醇的下降显著相关。
