Food insecurity is prevalent in Canada and may influence mental health, particularly among females. The present study examined the joint effect of female sex and food insecurity on mood disorders.
The study used data from 104,420 adults aged 18 years or older who participated in the 2017/2018 Canadian Community Health Survey (CCHS). Log-binomial models explored the independent and joint associations of female sex and food insecurity with the prevalence of self-reported mood disorder. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated. Relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (S) were used to assess the additive interaction of female sex and food insecurity. The complex survey design was taken into consideration.
The prevalence of mood disorder was 6.7% for males and 11.4% for females, with an adjusted prevalence ratio being 1.59 (95% CI 1.51, 1.68) for females versus males. Mood disorder was associated with moderate food insecurity (PR 2.06, 95% CI 1.91, 2.23) and severe food insecurity (PR 3.29, 95% CI 3.06, 3.55). There was a significant additive interaction between female sex and food insecurity in association with the prevalence of mood disorders among females aged 18 to 39 years (RERI 1.19, 95% CI 0.27,2.08).
Food insecurity was associated with an increased prevalence of mood disorders, especially in younger females. Interventions that facilitate access to food while being cognizant of the socioeconomic vulnerabilities of females may have substantial benefits for the prevention and management of mood disorders.
粮食不安全问题在加拿大普遍存在，可能会影响心理健康，尤其是在女性中。本研究考察了女性性别与粮食不安全对情绪障碍的联合影响。
该研究使用了104420名18岁及以上成年人的数据，这些人参与了2017/2018年加拿大社区健康调查（CCHS）。对数二项模型探讨了女性性别与粮食不安全与自我报告情绪障碍患病率之间的独立和联合关联。估计了患病率比值（PRs）和95%置信区间（CIs）。使用交互作用导致的相对超额风险（RERI）、归因比例（AP）和协同指数（S）来评估女性性别与粮食不安全的相加交互作用。考虑了复杂的调查设计。
男性情绪障碍患病率为6.7%，女性为11.4%，女性与男性的调整患病率比值为1.59（95%CI 1.51，1.68）。情绪障碍与中度粮食不安全（PR 2.06，95%CI 1.91，2.23）和重度粮食不安全（PR 3.29，95%CI 3.06，3.55）相关。在18至39岁女性中，女性性别与粮食不安全在情绪障碍患病率方面存在显著的相加交互作用（RERI 1.19，95%CI 0.27，2.08）。
粮食不安全与情绪障碍患病率增加相关，尤其是在年轻女性中。在认识到女性社会经济脆弱性的同时，促进粮食获取的干预措施可能对情绪障碍的预防和管理有很大益处。
