Evidence is lacking for the association of the behaviors of the 24 h movement guidelines including sleep duration, physical activity, screen time, and soft drink consumption with suicidality among adolescents.
Data were extracted from a national representative sample of Youth Risk Behavior Surveys (YRBS) in the United States from 2011 to 2019. Binary logistic regression models with complex sampling designs were used to explore the association of the recommendations of the 24 h movement guidelines and soft drink consumption with suicidality.
The total prevalence of suicidal ideation, suicide plan, suicide attempt, and suicide attempt with medical treatment was higher among adolescents who did not meet all the recommendations in the 24 h movement guidelines and had a higher level of soft drink consumption. Totally, not meeting all the recommendations of the 24 h movement guidelines was significantly associated with an increased risk of suicidal ideation (OR: 1.69, 95% CI: 1.30-2.19) and suicide plan (OR: 1.76, 95% CI: 1.34-2.33) compared with adolescents who meet all the recommendations. Soft drink consumption of ≥3 times/day was associated with an increased risk of suicidality including suicidal ideation, suicide plan, suicide attempt, and suicide attempt with medical treatment, regardless of sex. Soft drink consumption of ≥3 times/day was significantly associated with an increased risk of suicide attempt and suicide attempt with medical treatment, regardless of whether the recommendations of physical activity, screen time, and sleep duration were met.
Age-appropriate sleep duration, no more than 2 h of screen time per day, at least 1 h of physical activity per day as contained in the 24 h movement guidelines and less than one soft drink consumption per day are good targets to prevent involvement in suicidality. More actions for intervening in the movement and dietary behaviors among adolescents are needed to maintain physical and mental health.
缺乏证据表明 24 小时运动指南的行为（包括睡眠时间、体力活动、屏幕时间和软饮料消费）与青少年自杀意念有关。
数据来自美国全国代表性的青少年风险行为监测系统（YRBS）在 2011 年至 2019 年的数据。采用复杂抽样设计的二元逻辑回归模型探讨 24 小时运动指南推荐意见和软饮料消费与自杀意念的关系。
不符合 24 小时运动指南所有建议且软饮料消费水平较高的青少年，自杀意念、自杀计划、自杀企图和自杀未遂并接受治疗的总发生率较高。不符合 24 小时运动指南所有建议的青少年自杀意念（比值比[OR]：1.69，95%置信区间[CI]：1.30-2.19）和自杀计划（OR：1.76，95%CI：1.34-2.33）的风险显著高于符合所有建议的青少年。无论性别如何，每天软饮料饮用≥3 次与自杀意念、自杀计划、自杀企图和自杀未遂并接受治疗等自杀意念风险增加有关。无论是否符合体力活动、屏幕时间和睡眠时间的建议，每天软饮料饮用≥3 次与自杀企图和自杀未遂并接受治疗的风险增加显著相关。
适合年龄的睡眠时间、每天不超过 2 小时的屏幕时间、每天至少 1 小时的体力活动以及每天不超过 1 份软饮料是预防参与自杀意念的良好目标。需要采取更多措施干预青少年的运动和饮食行为，以维护身心健康。
