Previous studies indicate that obesity is a risk factor of suicide behaviors among adolescents. Whether this association has remained consistent during the ongoing obesity epidemic remains unknown. The time trends of the obesity-suicide association were examined using the 1999-2019 biannual Youth Risk Behavior Survey data (n = 161,606). Prevalence odds ratio of suicide behaviors among adolescents with obesity (vs. adolescents with no obesity) for each survey year and time trends using National Cancer Institute Joinpoint regression analysis was calculated. For each year post-baseline, there was a significant increase of prevalence odds ratio of 1.4 (1.2-1.6)-1.6 (1.3-2.0) for suicide ideation, 1.3 (1.1-1.7) -1.7 (1.4-2.0) for plan, and 1.3 (1.0-1.7) -1.9 (1.5-2.4) for an attempt, except for the 2013 survey for attempt (1.19 [0.9-1.6]). Significant positive trends were found from1999 to 2019 for ideation and plan, with biannual %-changes of + 0.92 and + 1.22%, respectively. Adolescents with obesity have consistently higher odds of engaging in suicide behaviors than their peers without obesity since the beginning of the United States obesity epidemic, and this association grew stronger as the obesity epidemic continued.
先前的研究表明，肥胖是青少年自杀行为的一个风险因素。在当前肥胖流行的情况下，这种关联是否一直保持不变尚不清楚。本研究使用 1999-2019 年两年一次的青少年风险行为调查数据（n=161606），考察了肥胖与自杀行为之间的时间趋势。使用国家癌症研究所 Joinpoint 回归分析，计算了肥胖青少年（vs. 非肥胖青少年）在每个调查年份的自杀行为的流行优势比（odds ratio，OR）及其时间趋势。与基线后每年相比，自杀意念的流行优势比显著增加了 1.4（1.2-1.6）-1.6（1.3-2.0），自杀计划的流行优势比显著增加了 1.3（1.1-1.7）-1.7（1.4-2.0），自杀企图的流行优势比显著增加了 1.3（1.0-1.7）-1.9（1.5-2.4），但在 2013 年的自杀企图调查中，流行优势比仅为 1.19（0.9-1.6）。1999 年至 2019 年，自杀意念和计划的显著正趋势，每两年的百分比变化分别为+0.92%和+1.22%。自美国肥胖流行开始以来，肥胖青少年发生自杀行为的几率一直高于非肥胖同龄人，而且随着肥胖流行的持续，这种关联变得更强。
