Is household food insecurity a determinant of weight status in patients with type 2 diabetes in rural areas?

Background: There is mixed evidence about food insecurity and overweight/obesity coexisting, however it is unclear about association between food insecurity and weight status in people with type 2 diabetes. Therefore, the aim of this study was to evaluate the relationship between food insecurity and weight status in individuals with type 2 diabetes in rural areas in Iran.    Methods: 1847 patients with type 2 diabetes who were residence in rural areas completed Household Food Security Scale (six-item short questionnaire). Logistic regression model was applied to assess the independent effect of food insecurity on weight status.    Results: Mean age of the study population was 62.6±11.8 years, and the majority of them were female (70.4%). Most of the study population (70.4%) had unhealthy weight status. Food insecurity affected more than 46% (n=852) of the households of the study population. According to weight status, more than 40% (n=565) of overweight and obese subjects and 60% (n=18) of underweight subjects lived in households with food insecurity. The results of multiple logistic regression model showed that food insecurity was not an independent significant predictor of overweight or obesity in patients with type 2 diabetes. However, low food security (LFS) was an independent significant predictor for underweight in patients with type 2 diabetes (OR=2.35, P=0.041).    Conclusion: It is concluded that food insecurity was frequent in all levels of weight status of patients with type 2 diabetes in rural regions.  However this association observed in underweight individuals but there was no significant overall relationship between household food insecurity and in overweight and obesity in this group of patients.
