Abstract Objective The objective was to analyze the occurrence and the associated factors with food insecurity and overweight among government-backed economy restaurant workers in one of the biggest cities in Brazil. Methods A sample comprised of 180 individuals and represented 76.0% of all economy restaurant workers in the city of Belo Horizonte. Food insecurity was identified through the Brazilian Food Security Scale, and excess weight was identified by the body mass index. Data collection included sociodemographic and occupational information, and also health and quality of life perception. Logistic regression models were applied to identify the association. Results Food insecurity and overweight prevalence levels were 24.0% and 66.7%, respectively. The odds of identifying food insecurity were 2.34 times higher among workers that perceived their quality of life to be regular/poor/very poor and 62.0% and 74.0% lower among workers from the 2nd and 3rd tertile of per capita income, respectively. Individuals ≥40 years old (Odds Ratio=2.69, Confidence Interval 95%:1.33-5.43) and food handlers (Odds Ratio=3.62, Confidence Interval 95%:1.68-7.81) had higher odds of being classified as overweight compared to reference categories. Workers with higher per capita income presented lower odds of being classified as overweight (Odds Ratio=0.40, Confidence Interval 95%:0.17-0,96). Conclusion It was evidenced an occurrence of overweight among government-backed economy restaurant workers, which was associated with age, income and job position. Food insecurity prevalence was associated with income and quality of life perception. Although the sample work in a food and nutritional security promotion program, it is necessary to recommend actions aimed at the promotion of healthy eating habits.
