title: Adherence to the 2010 Dietary Guidelines for Americans and the relationship to adiposity in young women.
abstract: OBJECTIVE
  To determine the relationship between adherence to the 2010 Dietary Guidelines for Americans and adiposity in young women with and without statistical adjustment for physical activity (PA).
  
  
  METHODS
  Participants included 324 young women (aged 17-25 years). The researchers measured dietary intake using the Dietary History Questionnaire and determined diet quality using the 2010 Healthy Eating Index (HEI-2010). BOD POD (Cosmed, Rome, Italy, 2006) and accelerometry were used to assess body fat and PA, respectively.
  
  
  RESULTS
  Women in the top quartile of HEI-2010 had significantly lower percent body fat than women in the lowest 3 quartiles (F = 3.36; P = .03). Controlling for objectively measured PA weakened this relationship by 20%. These young women (top quartile of HEI-2010) also had 0.37 odds (95% confidence interval, 0.16-0.85) of having body fat > 32%.
  
  
  CONCLUSIONS
  Young women whose diets most closely meet the 2010 Dietary Guidelines for Americans have lower adiposity.
