title: Which food patterns are predictors of obesity in Tehranian adults?
abstract: OBJECTIVE
  To determine whether changes in food patterns over a period of 6 years were related to obesity in Tehranian adults.
  
  
  METHODS
  Data on dietary intake, using the food frequency questionnaire, and anthropometry were obtained in 2 periods of the survey (1999-2001 and 2005-2007).
  
  
  METHODS
  Participants of the Tehran Lipid and Glucose Study.
  
  
  METHODS
  Two hundred six adults.
  
  
  METHODS
  Waist circumference, body mass index, and waist-to-hip ratio.
  
  
  METHODS
  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
  Results of this study indicate that increased adherence to the WDP and decreased adherence to the HDP could contribute to obesity.
