背景：关于心理社会因素与肥胖之间关系的研究提供了不同的结果。目的：目前的研究使用了一个具有全国代表性的美国成年人样本来调查种族、性别和年龄的交集如何改变身体质量指数（BMI）的社会心理相关因素。材料和方法：数据来自国家健康测量研究（NHMS），这是一项横断面研究，具有全国代表性的样本是35 - 89岁的黑人和白人（n = 3,648）。我们检验了BMI与身心生活质量、生活目标、慢性疾病数量以及种族、性别和年龄组歧视之间的双变量相关性。结果：在中年和老年白人女性、中年黑人男性、中年黑人女性和老年黑人女性中，较高的生活目标与较低的BMI相关，但与中年或老年白人男性和老年黑人男性无关。除老年白人男性外，所有人群的多发病与BMI呈正相关。在老年白人女性、老年黑人男性和女性中，高BMI与较差的精神生活质量有关，但与任何中年群体和老年白人男性无关。在所有人群中，高BMI与较差的身体生活质量有关。在老年白人女性中，日常歧视与BMI呈正相关，而在其他群体中则没有。在任何一组中，终身歧视都与BMI无关。结论：种族、性别和年龄决定了BMI与心理社会和健康的相关性。有必要进一步研究肥胖的社会心理相关因素的群体差异。
Background: Studies on the association between psychosocial factors and obesity have provided mixed findings.Objectives: Current study used a nationally representative sample of U.S. adults to investigate how intersection of race, gender and age alters the psychosocial correlates of body mass index (BMI).Materials and Methods: Data came from the national health measurement study (NHMS), a cross-sectional study with nationally representative sample of Black and White (n = 3,648) adults ages 35 - 89. We tested bivariate correlations between BMI and physical and mental quality of life, purpose in life, number of chronic medical conditions, and discrimination across race chi gender chi age groups.Results: Higher purpose in life was associated with lower BMI among middle aged and older White women, middle aged Black men, middle aged Black women, and older Black women but not middle aged or older White men and older Black men. There was a positive association between multi-morbidity and BMI in all groups other than older White men. High BMI was associated with poor mental quality of life among older White women, older Black men and women, but not any of middle aged groups, and older White men. High BMI was associated with poor physical quality of life a mongall groups. Everyday discrimination was positively associated with BMI among older White women but not any other group. Lifetime discrimination was not associated with BMI among any of the groups.Conclusions: Race, gender, and age shape psychosocial and health related correlates of BMI. There is a need for further research on group differences in psychosocial correlates of obesity.
