We examined the fast food consumption-suicide attempt relationship among 105,061 adolescents aged 12-15 years from 32 countries.
This study was based on cross-sectional data from the Global School-based Student Health Survey (GSHS), and included 4 low-income, 13 lower middle-income, 9 upper middle-income, and 6 high-income countries. Data on past 7-day fast food consumption and 12-month suicide attempts were collected. The association between fast food consumption and suicide attempts was investigated with multivariable logistic regression and meta-analysis while adjusting for sex, age, food insecurity (proxy of socioeconomic status), alcohol consumption, smoking, physical activity, obesity, carbonated soft drink consumption, and fruit and vegetable consumption.
Overall, the prevalence of fast food consumption was high (53.5%) and the proportion of suicide attempts was higher among consumers of fast food compared to non-consumers (11.8% vs. 8.3%). Of the 32 countries included in the study, a positive association between fast food consumption and suicide attempts was found in 26 countries although this was not statistically significant in all countries. The pooled OR (95% CI) based on a meta-analysis was 1.31 (1.17-1.46).
Since this was a cross-sectional study, it is not possible to draw any conclusions about causality or temporality in the associations assessed.
Fast food consumption is positively associated with suicide attempts in adolescents. Further research of longitudinal design is needed to confirm/refute our findings and explore the potential underlying mechanisms.
我们研究了来自 32 个国家的 105061 名 12-15 岁青少年的快餐消费与自杀未遂之间的关系。
本研究基于全球学校学生健康调查（GSHS）的横断面数据，包括 4 个低收入、13 个中下收入、9 个中上收入和 6 个高收入国家。收集了过去 7 天快餐消费和 12 个月自杀未遂的数据。通过多变量逻辑回归和荟萃分析，调整性别、年龄、食物不安全（社会经济地位的代表）、饮酒、吸烟、体育活动、肥胖、碳酸软饮料消费和水果和蔬菜消费等因素，调查了快餐消费与自杀未遂之间的关联。
总体而言，快餐消费的流行率很高（53.5%），与非消费者相比，快餐消费者的自杀未遂比例更高（11.8%比 8.3%）。在所研究的 32 个国家中，有 26 个国家发现快餐消费与自杀未遂之间存在正相关关系，尽管并非所有国家的相关性均具有统计学意义。基于荟萃分析的汇总 OR（95%CI）为 1.31（1.17-1.46）。
由于这是一项横断面研究，因此无法对评估的关联进行因果关系或时间性的任何结论。
快餐消费与青少年自杀未遂呈正相关。需要进一步进行纵向设计的研究来证实/反驳我们的发现，并探索潜在的潜在机制。
