To our knowledge, only few studies have analyzed the relationship between meeting the 24-h movement guidelines and suicidality in adolescents. The aim of this study was twofold: first, to examine the association between meeting the 24-h movement recommendations and suicidal ideation, suicide planning, and attempted suicide in a representative sample of adolescents from the U.S.; and second, to test whether age group, sex, or race moderate these associations.
This is a cross-sectional study including pooled data from the 2011, 2013, 2015, 2017, 2019, and 2021 high school Youth Risk Behavior Surveys (YRBS). A total sample of 44,734 participants (48.5 % females) was included. The recommendations of the 24-h movement guidelines included physical activity, screen time, and sleep duration. Suicidality was examined considering three suicide-related behaviors: suicidal ideation (yes/no), suicide planning (yes/no), and attempted suicide (at least one time or more during the past 12 months).
Adolescents who met all three recommendations showed a lower likelihood of suicidal ideation (odds ratio [OR] = 0.49, 95 % confidence interval [CI] 0.37 to 0.64, p < 0.001), suicide planning (OR = 0.51, 95 % CI 0.37 to 0.68, p < 0.001), and attempted suicide (OR = 0.66, 95 % CI 0.44 to 0.96, p = 0.038) than those who did not meet all the recommendations. Overall, when younger adolescents, female adolescents, and adolescents of minority races met the 24-h movement recommendations, they had lower odds of suicide-related outcomes than when they did not.
This is a cross-sectional study using self-reported data. It is not possible to establish cause-and-effect relationships, and the results could be influenced by some biases.
This study suggests that meeting the 24-h movement recommendations could play a relevant role in the prevention of suicidal ideation, planning suicide, and attempted suicide in a nationwide sample from the U.S. adolescents.
据我们所知，只有少数研究分析了青少年达到 24 小时运动指南与自杀意念之间的关系。本研究的目的有两个：首先，在美国代表性青少年样本中，检验达到 24 小时运动建议与自杀意念、自杀计划和自杀未遂之间的关联；其次，测试年龄组、性别或种族是否调节这些关联。
这是一项横断面研究，包含了 2011、2013、2015、2017、2019 和 2021 年高中青少年风险行为调查（YRBS）的汇总数据。共纳入 44734 名参与者（48.5%为女性）。24 小时运动指南的建议包括身体活动、屏幕时间和睡眠时间。自杀意念通过三种与自杀相关的行为来评估：自杀意念（是/否）、自杀计划（是/否）和自杀未遂（过去 12 个月至少有一次或多次）。
青少年达到所有三项建议时，自杀意念（比值比 [OR] = 0.49，95%置信区间 [CI] 0.37 至 0.64，p<0.001）、自杀计划（OR = 0.51，95%CI 0.37 至 0.68，p<0.001）和自杀未遂（OR = 0.66，95%CI 0.44 至 0.96，p=0.038）的可能性较低。总体而言，年轻青少年、女性青少年和少数族裔青少年达到 24 小时运动建议时，自杀相关结局的可能性低于未达到建议者。
这是一项使用自我报告数据的横断面研究。不可能建立因果关系，结果可能受到一些偏差的影响。
本研究表明，在美国全国青少年样本中，达到 24 小时运动建议可能对预防自杀意念、计划自杀和自杀未遂具有重要作用。
