Identifying oneself as overweight is a risk factor for poor mental health and suicidality independent from objective weight status. The stigma associated with heavier body weight has risen in recent decades and this may have exacerbated the detrimental mental health effects of perceived overweight. In this study, we examined the association between perceived overweight and suicidality in a nationally representative sample (N = 115,180) of US adolescents assessed from 1999 to 2017. We drew on data from the Youth Risk Behavior survey, a biennial population-based survey of students in grades 9-12. Suicidality was gauged by participant reports of past-year suicidal ideation, suicide plans, or suicide attempts. Across all waves, perceived overweight (vs. perceived "normal" weight) predicted a 7.7 percentage point (p < 0.001) increased risk of suicidality after adjustment for age, sex, ethnicity, and BMI. The risk of suicidality associated with perceived overweight increased from 5.7 percentage points in 1999-2001 to 10.1 points in 2015-2017, a difference of 4.4 points (p = 0.001). This growth was most evident after 2009 and was apparent across suicidality measures. Among US adolescents, perceiving one's body as overweight increases risk of suicidality and this risk appears to have grown substantially from 2009 to 2017.
将自己视为超重是心理健康和自杀倾向的一个风险因素，与客观体重状况无关。近年来，与较重体重相关的耻辱感有所上升，这可能加剧了超重感知对心理健康的不利影响。在这项研究中，我们在一个具有全国代表性的美国青少年样本（N=115180）中检查了超重感知与自杀倾向之间的关联，该样本从 1999 年到 2017 年进行了评估。我们利用了来自青年风险行为调查的数据，这是一项对 9-12 年级学生进行的两年一次的基于人群的调查。自杀倾向通过参与者报告过去一年的自杀意念、自杀计划或自杀尝试来衡量。在所有波次中，与感知“正常”体重相比，超重（vs. 感知“正常”体重）在调整年龄、性别、种族和 BMI 后预测自杀倾向的风险增加了 7.7 个百分点（p<0.001）。与超重感知相关的自杀倾向风险从 1999-2001 年的 5.7 个百分点增加到 2015-2017 年的 10.1 个百分点，差异为 4.4 个百分点（p=0.001）。这种增长在 2009 年后最为明显，在各种自杀倾向衡量标准中都很明显。在美国青少年中，将自己的身体视为超重会增加自杀倾向的风险，而且这种风险似乎从 2009 年到 2017 年大幅增加。
