Food Consumption Changes of Adult Women between 1977 and 1985
利用1977和1985年美国全国代表性样本，分析19至50岁女性食物组消费比例、消费量及变化决定因素，发现按脂肪和膳食纤维定义的食物组消费发生显著变化，且标准人口和社会经济因素对消费趋势的解释力随时间变化。
Abstract Nationally representative samples of U.S. women aged nineteen to fifty are used to examine comparable food group consumption data collected in 1977 and 1985. Changes in the proportion of women consuming each food group, quantities consumed by users, and the determinants of consumption changes over time are identified. Significant shifts in consumption of food groups defined by fat and dietary fiber criteria are measured in this research. While standard demographic and socioeconomic factors explain significant amounts of cross‐section food group consumption variation, the effects of these factors vary considerably between 1977 and 1985 and explain most of the food group consumption trends.
