To examine the trajectory of suicidal ideation in relation to perceived overweight from adolescence to young adulthood.
Four waves (1995-2008) of the National Longitudinal Study of Adolescent Health that prospectively followed up a nationally representative sample of United States middle and high school students (N = 6,504) were analyzed using hierarchical generalized linear models with a logit link function.
Overall, suicidal ideation tended to decrease with age (logit coefficient [coef.] = -.07, p < .001). Participants who perceived themselves as overweight were more likely to think about committing suicide, especially in females, even after controlling for rigorously measured depressive symptoms (coef. = .14, p < .01). Girls were more likely than boys to have suicidal ideation at age 10 (coef. = -.31, p < .001). However, the association between suicidal ideation and perceived overweight became weaker and the prevalence of suicidal ideation became lower as participants grew older. The downward trend in suicidal ideation was steeper in females than in males (coef. = .03, p < .001), with males actually showing a higher prevalence of suicidal ideation than females around 20-30 years of age. Random effects of age, depression, and perceived overweight were insignificant, which indicated that participants did not vary significantly in terms of effects of these variables on suicidal ideation.
The results of this study underline the need for development of family, school, and community interventions to address body weight perception to reduce suicidal ideation and attempts, especially among female teenagers.
探讨从青春期到青年期，与超重相关的自杀意念轨迹。
使用分层广义线性模型和对数链接函数，对美国中学和高中的全国代表性样本（N=6504）进行了前瞻性随访的国家青少年健康纵向研究的 4 个波次（1995-2008 年）进行了分析。
总体而言，自杀意念随年龄的增长而下降（对数系数[coef.]=-.07，p<.001）。即使在严格测量的抑郁症状得到控制后，自我认为超重的参与者更有可能考虑自杀，尤其是女性，（coef.=.14，p<.01）。与男孩相比，女孩在 10 岁时更有可能有自杀意念（coef.=-.31，p<.001）。然而，随着参与者年龄的增长，自杀意念与超重之间的关联变得较弱，自杀意念的发生率变得较低。与男性相比，女性的自杀意念下降趋势更为陡峭（coef.=.03，p<.001），大约在 20-30 岁时，男性实际上比女性有更高的自杀意念发生率。年龄、抑郁和超重的随机效应不显著，这表明参与者在这些变量对自杀意念的影响方面没有显著差异。
本研究结果强调需要制定家庭、学校和社区干预措施，以解决体重感知问题，从而减少自杀意念和尝试，特别是在女性青少年中。
