Existing research has established the detrimental effects of food insecurity on health. However, understanding of the social conditions that may moderate this relationship remains limited. To address this gap, the study investigates two questions: First, does marital status moderate the association between food insecurity and self-rated health? Second, if such moderation exists, does its impact vary based on gender? Data from the 2017-2018 Canadian Community Health Survey, a nationally representative survey conducted by Statistics Canada (n =101 647), were utilized for this investigation. The findings demonstrated that individuals living in food-insecure households reported poorer self-rated mental and general health. However, the negative impact of food insecurity on both health outcomes was less pronounced among married individuals than among their unmarried counterparts. Furthermore, the stress-buffering role of marriage was found to be more substantial among men than among women. In light of the significant stress-buffering role of marriage revealed in this study, it is crucial for policies to aim at providing comparable coping resources to unmarried individuals, particularly women.
