参加巴尔的摩纵向衰老研究的 180 名男性在 3 个时间段（1961-1965 年、1966-1970 年和 1971-1975 年）的每个时期提供了 7 天的饮食日记。这些人是受过高等教育的中上层阶级群体。在写第一篇日记时，他们的年龄在 35-74 岁之间。通过同时利用 3 种类型的研究设计（即横截面、纵向和时间序列）来分析数据的年龄、队列和时间对饮食的影响。考虑的营养素包括卡路里、蛋白质、碳水化合物、脂肪、饱和脂肪酸、多不饱和脂肪酸和胆固醇。衰老对卡路里、脂肪、饱和脂肪酸和胆固醇的摄入量有负面影响。没有观察到任何这些营养素的群组效应。随着时间的推移，碳水化合物和胆固醇的摄入量下降，而多不饱和脂肪酸的摄入量增加。
Seven-day dietary diaries were provided by 180 men participating in the Baltimore Longitudinal Study of Aging during each of 3 time periods (1961-1965, 1966-1970 and 1971-1975). These men are a highly educated, upper-middle class group. At the time of their 1st diary, they were aged 35-74 yr. The data were analyzed for aging, cohort and time effects on diet by utilizing 3 types of research designs concurrently, i.e., cross-sectional, longitudinal and time series. The nutrients considered were calories, protein, carbohydrate, fat, saturated fatty acids, polyunsaturated fatty acids and cholesterol. Aging had a negative effect on intake of calories, fat, saturated fatty acids and cholesterol. Cohort effects were not observed for any of these nutrients. Over time, intake of carbohydrates and cholesterol declined, while intake of polyunsaturated fatty acids rose.
