Objectives:
To determine whether changes in food patterns over a period of 6 years were related to obesity in Tehranian adults.
Design:
Data on dietary intake, using the food frequency questionnaire, and anthropometry were obtained in 2 periods of the survey (1999-2001 and 2005-2007).
Setting:
Participants of the Tehran Lipid and Glucose Study.
Participants:
Two hundred six adults.
Main Outcome Measures:
Waist circumference, body mass index, and waist-to-hip ratio.
Analysis:
Food patterns were derived using factor analysis.
Results:
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).
Conclusions And Implications:
Results of this study indicate that increased adherence to the WDP and decreased adherence to the HDP could contribute to obesity.
