Food Insufficiency and Depression

Abstract

Using National Population Health Survey data and the stress process model, this study investigates the relationship between food insufficiency and the risk of depression among Canadian adults. The study presents three principal findings. First, after controlling for conventional socioeconomic and socio-demographic variables, food insufficiency increases the risk of depression and actually predicts this risk better than measures of low income, main source of income, and education. Second, the negative effect of food insufficiency is not attributable to social resources disparities, even though these resources significantly reduce the size of the effect. Third, the effects of food insufficiency on depression are generally stronger for women than for men, but the results also indicate that single fathers from food insufficient households face more depression than other groups, including single mothers.
