To examine the relationship between diet, particularly dietary fat intake, and body mass index (BMI).
Prospective study of adults who participated in the 1989 and 1991 China Health and Nutrition Survey.
3484 adults aged 20-45 at baseline (1989) survey.
Measurement of dietary intake with replicated 24 h dietary recalls. Anthropometric measurements. Measurements of physical activity, smoking habit and socio-economic factors.
Change in fat intake was positively associated with change in BMI in men (beta=0.00036, P=0.0001), and change in physical activity level was inversely associated with change in BMI in women (beta=-0.12, P=0.02). Energy intake, physical activity and major socio-economic factors were related to BMI in cross-sectional analysis.
Diet is becoming an increasingly important determinant of body weight in this population, where fat and energy consumption has been increasing steadily during the past decade.
研究饮食，特别是膳食脂肪摄入量与体重指数（BMI）之间的关系。
对参与1989年和1991年中国健康与营养调查的成年人进行前瞻性研究。
在基线（1989年）调查中年龄为20 - 45岁的3484名成年人。
通过重复24小时饮食回顾来测量饮食摄入量。人体测量。身体活动、吸烟习惯和社会经济因素的测量。
男性脂肪摄入量的变化与BMI的变化呈正相关（β = 0.00036，P = 0.0001），女性身体活动水平的变化与BMI的变化呈负相关（β = -0.12，P = 0.02）。在横断面分析中，能量摄入、身体活动和主要社会经济因素与BMI有关。
在该人群中，饮食正成为体重的一个越来越重要的决定因素，在过去十年中，脂肪和能量消耗一直在稳步增加。
