BACKGROUND Youth psychiatric hospitalizations have been associated with negative outcomes, including premature death and post-discharge self-harm. Identifying risk factors for youth psychiatric hospitalization is crucial for informing prevention strategies. We aimed to evaluate the risk factors for psychiatric hospitalizations among low-income youth in Brazil. METHODS This cohort study used interpersonal violence and psychiatric hospitalization data linked to the 100 Million Brazilian Cohort baseline. We considered 9 985 917 youths aged 5-24 years who enrolled at the baseline, between 2011 and 2018. We estimated the incidence rate (IR) with 95% confidence interval (CI) for psychiatric hospitalization by calculating the number of hospitalizations per person-year in 100 000 individuals at risk. The multilevel, multivariate Cox proportional hazards regression estimated the hazard risks (HR) with 95% CI for psychiatric hospitalization. RESULTS The IR of psychiatric hospitalization was 12.28 per 100 000 person-years (95% CI, 11.96-12.6). Interpersonal violence victimization was the main risk factor for youth psychiatric hospitalization (HR, 5.24; 95% CI, 4.61-5.96). Other risk factors for psychiatric hospitalization included living with the oldest family member who had low education (HR, 2.51; 95% CI, 2.16-2.91) or was unemployed (HR, 1.49; 95% CI, 1.36-1.62), living with seven or more family members (HR, 1.84; 95% CI, 1.49-2.26) and being male (HR, 1.28; 95% CI, 1.21-1.36). CONCLUSIONS Urgent action is needed to prevent youth from suffering violence. Addressing this may alleviate the mental health burden in developmental ages, benefiting youth, families and the government through reduced costs in preventable psychiatric hospitalizations.

低收入青年住院风险：来自 1 亿巴西队列的纵向发现。


背景 青年精神病住院与负面结果有关，包括过早死亡和出院后自残。确定青少年精神病住院的危险因素对于制定预防策略至关重要。我们旨在评估巴西低收入青年精神科住院的危险因素。方法 该队列研究使用了与 1 亿巴西队列基线相关的人际暴力和精神病住院数据。我们考虑了 9 985 年至 2011 年间在基线时入学的 24-24 名青年。我们通过计算 100 000 名高危个体中每人每年的住院人数，估计了精神科住院的发生率 （IR） 和 95% 置信区间 （CI）。多水平、多变量 Cox 比例风险回归估计了精神病住院的风险风险 （HR） 和 95% CI。结果 精神科住院的 IR 为 12.28/100 000 人年 （95% CI，11.96-12.6）。人际暴力受害是青少年精神病住院治疗的主要危险因素 （HR， 5.24;95% CI， 4.61-5.96）。精神科住院的其他风险因素包括与受教育程度低（HR，2.51;95% CI，2.16-2.91）或失业（HR，1.49;95% CI，1.36-1.62）的最年长家庭成员住在一起，与七个或更多家庭成员住在一起（HR，1.84;95% CI，1.49-2.26）和男性（HR，1.28;95% CI，1.21-1.36）。结论 需要采取紧急行动来防止青少年遭受暴力。解决这个问题可能会减轻发育年龄的心理健康负担，通过降低可预防的精神科住院费用，使青年、家庭和政府受益。
