背景资料：目的：探讨遗传和环境因素对饮食行为、体重指数（BMI）、高脂食物反应的认知和情绪方面的影响及其相互关系（17-82岁;来自英国和芬兰的17%M和83%F）完成了修订版的三因素饮食问卷（TFEQ-R18），并报告了4个甜和脂肪和咸和脂肪的食物项目（6项在英国和5项在芬兰）的喜好和使用频率。遗传建模是通过使用线性结构方程。结果：遗传估计分别计算的国家和性别，他们是26-63%的认知克制，45-69%的不受控制的饮食，9-45%的情绪化饮食，分别。在对脂肪食物的喜好和使用频率的变化中，24-54%归因于个体间的遗传差异。BMI和脂肪食物的使用或喜好之间没有显著的相关性。然而，BMI与所有节食行为呈正相关（主要是遗传相关）（遗传r = 0.16-0.51），并且与脂肪食物的使用和喜好等级相关。不受控制的饮食与喜欢咸和脂肪食物的遗传和环境相关（遗传和环境r = 0.16），情绪化饮食与喜欢甜和脂肪食物的遗传相关（遗传r = 0.31）。结论：BMI和饮食之间的关系似乎是通过节食行为介导的。饮食咨询应该关注不健康的饮食行为，而不仅仅是对食物使用的直接建议。
Background: The relation between body weight and energy-dense foods remains unclear.Objective: We estimated the effects of genetic and environmental factors on cognitive and emotional aspects of dieting behavior, body mass index (BMI), and responses to fatty foods and on their relations.Design: A total of 1326 adult twin persons (aged 17-82 y; 17% M and 83% F) from the United Kingdom and Finland completed the revised version of the Three-Factor Eating Questionnaire (TFEQ-R18) and reported the liking and use-frequency of 4 sweet-and-fatty and salty-and-fatty food items (6 items in the United Kingdom and 5 items in Finland). Genetic modeling was done by using linear structural equations.Results: Heritability estimates were calculated separately for the countries and sexes; they were 26-63% for cognitive restraint, 45-69% for uncontrolled eating, and 9-45% for emotional eating, respectively. Of the variation in liking and use-frequency of fatty foods, 24-54% was attributed to interindividual genetic differences. No significant correlations were observed between BMI and fatty food use or liking. However, BMI was positively (mostly genetically) correlated (genetic r = 0.16-0.51) with all of the dieting behaviors, and they correlated with fatty food use and liking ratings. Uncontrolled eating was both genetically and environmentally associated with liking for salty-and-fatty foods (genetic and environmental r = 0.16), and emotional eating was genetically associated with liking for sweet-and-fatty foods (genetic r = 0.31).Conclusions: The relation between BMI and diet appears to be mediated through dieting behaviors. Dietary counseling should focus on unhealthy dieting behaviors rather than only on direct advice on food use.
