Suicidal behaviors among adolescents is a major public health concern. Psychological factors have been extensively studied known risks linked to suicidal behaviors in the general population. However, the association between food insecurity and suicidal behaviors is less researched, particularly in low and middle-income countries. The present study sought to assess the link between food insecurity and suicide behaviors among in-school adolescents.
The present study was based on the secondary analysis of the first nationally representative sample of the 2014 Tanzania Global School-based Student Health Survey (GSHS). A total sample of 3,793 in-school adolescents was included in the present analysis. The primary independent variable was food insecurity while the dependent variables of interest were suicide ideation and suicide attempt. Chi-square χ and multivariate logistic regression were used to ascertain the measure of statistical association. In all analyses, a p < 0.05 was considered statistically significant.
Of the 3,793 in-school adolescents, 254 (6·7%) were food insecure. A significantly large proportion of adolescents with suicidal ideation and suicidal attempt were food insecure than their counterparts, respectively. In the adjusted multivariate model, food insecure adolescents were more likely to have experienced suicidal ideation and suicidal attempt: [AOR; 1·8 95% C. I; 1·3-2·5] and [AOR; 2·4, 95% C. I; 1·7-3·3]; p < 0.001, respectively.
Food insecurity was an independent predictor of suicidal behaviors among in-school adolescents. An intervention that targets food security at the school level may protect adolescents of food insecure household from suicidal behaviors. Nevertheless, school-based mental health screening, evaluation, and promotion may be needed for adolescents with suicidal behaviors.
青少年自杀行为是一个主要的公共卫生关注点。心理因素已被广泛研究,已知与普通人群中的自杀行为相关的风险因素。然而,食物不安全与自杀行为之间的关联研究较少,特别是在中低收入国家。本研究旨在评估在校青少年中食物不安全与自杀行为之间的联系。
本研究基于 2014 年坦桑尼亚全球学校学生健康调查(GSHS)的首次全国代表性样本的二次分析。本分析共纳入 3793 名在校青少年。主要自变量是食物不安全,而感兴趣的因变量是自杀意念和自杀企图。使用卡方 χ2 和多变量逻辑回归来确定统计学关联的度量。在所有分析中,p<0.05 被认为具有统计学意义。
在 3793 名在校青少年中,有 254 名(6.7%)存在食物不安全。有自杀意念和自杀企图的青少年中,食物不安全的比例明显高于他们的同龄人。在调整后的多变量模型中,食物不安全的青少年更有可能经历自杀意念和自杀企图:[AOR;1.8 95%CI;1.3-2.5]和[AOR;2.4,95%CI;1.7-3.3];p<0.001)。
食物不安全是在校青少年自杀行为的一个独立预测因素。针对学校层面的食物安全的干预措施可能会保护来自食物不安全家庭的青少年免受自杀行为的影响。然而,可能需要对有自杀行为的青少年进行基于学校的心理健康筛查、评估和促进。
