目的：男同性恋、女同性恋和双性恋青年可能会对自己的身体感到不满。我们研究了性取向的差异，自我感知的体重状况和潜在危险的体重控制行为的患病率在一个有代表性的样本的adolescents.Methods：数据来自12,984年之间的青少年在2003年和2009年超过四个周期的马萨诸塞州青少年危险行为调查，全州范围内的九至12年级学生的调查。自我感觉体重状况与过去一个月的不良体重控制行为（禁食>24小时，使用减肥药，呕吐或使用泻药）在男同性恋，双性恋，或自我认定的异性恋青年与同性伴侣，不确定的青年，和纯异性恋青年之间进行比较，使用logistic回归，调整年龄和种族/民族。与纯异性恋男性相比，有同性伴侣的异性恋男性和双性恋男性更容易自我感觉超重，尽管他们的体重正常或体重不足（校正比值比[AOR]，2.61; 95%置信区间[CI]，1.68-4.05; AOR，2.56; 95% CI，1.64-4.00）。与纯异性恋女性相比，女同性恋者和双性恋女性更可能自我感知为健康体重或体重不足，尽管超重或肥胖（分别为，AOR，3.17; 95%CI，1.15-8.71;和AOR，2.00; 95%CI，1.20-3.33）。不健康的体重控制行为在性少数男性中明显更普遍（32.5%; AOR，4.38; 95% CI，3.38-5.67）和女性（34.7%; AOR，2.27; 95% CI，1.85-2.78）结论：1/3的性少数青少年存在控制体重的危险行为。未来的研究应该调查潜在的机制，并确定临床医生是否应该定期筛查这些行为。(C)2014年青少年健康和医学协会。All rights reserved.
Purpose: Gay, lesbian, and bisexual youth may experience significant body dissatisfaction. We examined sexual orientation differences in self-perceived weight status and the prevalence of potentially dangerous weight control behaviors in a representative sample of adolescents.Methods: Data were obtained from 12,984 youth between 2003 and 2009 over four cycles of the Massachusetts Youth Risk Behavior Survey, a statewide survey of ninth-through 12th-grade students. Self-perceived weight status and past-month unhealthy weight control behaviors (fasting >24 hours, using diet pills, and vomiting or using laxatives) were compared among gay/lesbian, bisexual, or self-identified heterosexual youth with same-sex partners, unsure youth, and exclusively heterosexual youth using logistic regression, adjusting for age and race/ethnicity.Results: Compared with exclusively heterosexual males, heterosexual males with prior same-sex partners and bisexual males were more likely to self-perceive as overweight despite being of healthy weight or underweight (respectively, adjusted odds ratio [AOR], 2.61; 95% confidence interval [CI], 1.68-4.05; and AOR, 2.56; 95% CI, 1.64-4.00). Compared with exclusively heterosexual females, lesbians and bisexual females were more likely to self-perceive as being of healthy weight or underweight despite being overweight or obese (respectively, AOR, 3.17; 95% CI, 1.15-8.71; and AOR, 2.00; 95% CI, 1.20-3.33). Unhealthy weight control behaviors were significantly more prevalent among sexual minority males (32.5%; AOR, 4.38; 95% CI, 3.38-5.67) and females (34.7%; AOR, 2.27; 95% CI, 1.85-2.78) when considered together relative to exclusively heterosexual males (9.7%) and females (18.8%).Conclusions: One third of sexual minority youth engage in hazardous weight control behaviors. Future research should investigate underlying mechanisms and determine whether clinicians should routinely screen for these behaviors. (C) 2014 Society for Adolescent Health and Medicine.
