Methods: This is a cross-sectional study of 273 workers from seven restaurants located in the city of Rio de Janeiro, Brazil. We applied a questionnaire with different scales and anthropometric measurements were taken. Assessment of food insecurity was performed using the Brazilian Food Insecurity Scale, classifying individuals in food security and food insecurity. The analyses were performed by calculating the gross and adjusted odds ratio. The logistic regression was performed considering three groups of variables: socio-economic, employment and health. Results: The estimated prevalence of food insecurity was 53.7%. The variables: education (OR=2.39; 95%CI=1.38-4.16), time working in kitchens <29 months (OR=2.72; 95%CI=1.44-5.16) and opinion on the satisfaction with food composition and regularity (OR=2.01; 95%CI=1.12-3.57) were significantly associated with food insecurity. Conclusion: Although the study population find themselves inserted into a social facility to promote food security, food insecurity results are worrying. Additionally, factors like lower education and less time working in restaurants increased the chance to realize their households in food insecurity.
