Examining associations of food insecurity with major depression among older adults in the wake of the Great Recession

As a psychosocial stressor, the degree to which food insecurity impacts major depression may be dependent on macro-level context, which can be examined in the wake of the Great Recession. The objective of this study was to determine (1) whether food insecurity transition status (i.e. initially food insecure, becoming food insecure, and remaining food insecure vs. not food insecure) was associated with major depression in older adults and; (2) whether this association was moderated by macro-level context. Data came from the United States Health and Retirement Study, 2008-2016. Multivariable logistic regression across all years revealed that major depression was associated with any exposure to food insecurity, however; this association was moderated by time period. Remaining food insecure was associated with major depression during all time periods. In contrast, becoming food insecure was associated with major depression in the years during and immediately following the Recession, but not in later time periods. Findings suggest that associations of food insecurity with major depression among older adults are moderated by macro-level context, consistent with theories of social comparison and relative disadvantage. Food insecurity may represent an important risk factor for major depression and mental health disparities across socioeconomic strata in old age. Thus, policies that increase access to food assistance programs or improve the quality of local food environments may buffer against the impact of food insecurity on depression and associated complications among older adults.
