To determine whether changes in food patterns over a period of 6 years were related to obesity in Tehranian adults.
Data on dietary intake, using the food frequency questionnaire, and anthropometry were obtained in 2 periods of the survey (1999-2001 and 2005-2007).
Participants of the Tehran Lipid and Glucose Study.
Two hundred six adults.
Waist circumference, body mass index, and waist-to-hip ratio.
Food patterns were derived using factor analysis.
Three dietary patterns, the healthful (HDP), the western (WDP), and the mix, were identified. Increased WDP score was directly related to change in body mass index (β = .41, R(2) = 0.22, P < .001) among overweight/obese individuals. Alterations in waist circumference was better predicted by increased WDP score (β = .49, R(2) = 0.21, P < .01) than by increased HDP score (β = -.20, R(2) = 0.11, P < .05). Subjects in the higher quartile of increased HDP score had lesser change in waist-to-hip ratio (β = -.77, R(2) = 0.43, P < .01).
Results of this study indicate that increased adherence to the WDP and decreased adherence to the HDP could contribute to obesity.
确定在 6 年内食物模式的变化是否与德黑兰成年人的肥胖有关。
使用食物频率问卷在调查的两个时期（1999-2001 年和 2005-2007 年）获取有关饮食摄入和人体测量学的数据。
德黑兰血脂和血糖研究的参与者。
206 名成年人。
腰围、体重指数和腰臀比。
使用因子分析得出食物模式。
确定了三种饮食模式，即健康（HDP）、西方（WDP）和混合模式。超重/肥胖个体中，WDP 评分的增加与体重指数的变化直接相关（β=0.41，R²=0.22，P<0.001）。腰围的变化更好地由 WDP 评分的增加来预测（β=0.49，R²=0.21，P<0.01），而不是 HDP 评分的增加（β=-0.20，R²=0.11，P<0.05）。HDP 评分增加的较高四分位数的受试者腰围臀比变化较小（β=-0.77，R²=0.43，P<0.01）。
本研究结果表明，增加对 WDP 的依从性和减少对 HDP 的依从性可能导致肥胖。
