Are awareness of dietary fat intake and actual fat consumption associated?--a Dutch-American comparison.

Abstract：

OBJECTIVES:To compare dietary fat intake, the accuracy of individuals' awareness about their fat intake, and sociodemographic and psychosocial correlates of awareness, in Dutch and American samples of employed adults. A discrepancy between objective dietary intake data and subjective self-evaluation of dietary fat consumption has been recognized in the past and might undermine healthy diet promotion interventions, and this is important because people who believe that their diets are healthful are less likely to be interested in making changes. Further, international comparisons have not been examined to date. DESIGN:Data collected for the baseline surveys of the 'Healthy Bergeijk' study in the Netherlands and the 'Working Well Trial' in the United States were compared. SUBJECTS:Working adults from a Dutch community health intervention study (n = 768) and an American worksite health promotion trial (n = 15,440). MAIN OUTCOME MEASURES:Objectively assessed dietary fat intake, measured by food frequency questionnaires, and subjective ratings of fat intake (self-rated fat intake). RESULTS:Findings show that the Dutch respondents had higher objectively assessed fat intake and lower subjective ratings of fat intake (P < 0.001). American respondents perceived their diets as higher in fat, more often stated their intentions to reduce fat intake, and were slightly more likely to make realistic estimates of their dietary fat. Dutch subjects were significantly more likely to underestimate their fat intakes. In both samples, women were most likely to underestimate their fat consumption and the most educated persons were most likely to be realistic. CONCLUSIONS:A substantial proportion of adults, both in the United States and the Netherlands, lack accurate awareness about how much fat they consume, though errors tend to be in opposite directions in the two countries. This study is an important first step toward broadening our international understanding of human dietary behavior for disease prevention.
