这项研究旨在通过检查虐待儿童的历史、与体重相关的行为和社会人口统计学来解释BMI中的性取向差异。我们使用了从1996年(年龄12-14岁)到2007年(年龄20-25岁)之间的九个波的7960名女性和5992名男性的数据。使用重复测量的体重指数(公斤/平方米)作为连续结果，根据虐儿史、与体重相关的行为和社会人口统计学进行调整的性别分层潜在二次增长模型。报告了17岁时的BMI(截距)和一年的BMI变化(斜率)。与完全异性恋女性相比，双性恋女性在17岁时有更高的体重指数(β=1.59，95%CI=1.00，2.18)，并且一年内的体重指数增幅更大(β=0.09，95%CI=0.03，0.14)。与完全异性恋男性相比，男同性恋者的体重指数在一年内的增幅较小(β=−.19，95%CI=−.25，−.12)。男性在17岁时的BMI没有观察到性取向差异，但男同性恋在25岁时的BMI比完全异性恋的男性低2个单位。在女性中，性取向差异仍然存在，但在控制了虐儿史、与体重相关的行为和社会人口统计学因素后，差异略有减弱。在男性中，虐待儿童和与体重相关的行为的增加并没有改变一年BMI增加的估计差异。BMI中的性取向差异部分是由虐待儿童和女性的体重相关行为解释的。需要更多的研究来探索这些差异在女性和男性中的其他驱动因素。
This research aimed to explain sexual orientation disparities in BMI by examining child abuse history, weight-related behaviors, and sociodemographics. We used data from 7960 females and 5992 males from the prospective Growing Up Today Study over nine waves between 1996 (ages 12–14 years) and 2007 (ages 20–25 years). Using repeated measures of BMI (kg/m2) as a continuous outcome, gender-stratified latent quadratic growth models adjusted for child abuse history, weight-related behaviors, and sociodemographics. BMI at age 17 years (intercept) and one-year change in BMI (slope) are reported. Bisexual females had higher BMI at age 17 years (β = 1.59, 95% CI = 1.00, 2.18) and displayed greater one-year increases in BMI (β = .09, 95% CI = .03, .14), compared to completely heterosexual females. Gay males displayed smaller one-year increases in BMI (β = − .19, 95% CI = −.25, −.12), compared to completely heterosexual males. No sexual orientation differences in BMI at age 17 years were observed for males, but gay males’ BMI at age 25 was less than completely heterosexual males by 2 units. Among females, sexual orientation differences remained but were slightly attenuated after controlling for child abuse history, weight-related behaviors, and sociodemographics. Among males, the addition of child abuse and weight-related behaviors did not change the estimated difference in one-year BMI increases. Sexual orientation differences in BMI were partly explained by child abuse and weight-related behaviors in females. More research is needed to explore additional drivers of these disparities among both females and males.
