Food insecurity and malnutrition in older adults from the Family Health Strategy in the Northeast of Brazil

Introduction: Food insecurity (FI) is a state characterized by instability and irregularity of access to food. This condition has negative impacts on dietary intake, affecting nutritional status and health condition. Objective: To evaluate the association between malnutrition and FI among communitydwelling older adults attended to under the Family Health Strategy (FHS). Materials and methods: This is a cross-sectional study conducted using communitydwelling older adults attended to under the FHS in the municipality of Barreiras, in Bahia, Brazil. Between 2017 e 2018, we collected demographic, social, economic, health condition, lifestyle, anthropometric, and food consumption data. We evaluated nutritional status using the Mini Nutritional Assessment (MNA) and we assessed FI with the Brazilian Food Insecurity Scale (EBIA). Besides the chi-squared test, we carried out a binary logistic regression to verify the association between malnutrition and FI, adjusted for possible confounding factors. The significance level was p<0.05. Results: We evaluated 307 older adults with a mean age of 70.4 (±7.5 years). The prevalence of malnutrition/risk of malnutrition was 35.2% and that of FI was 63.5%. Households with older adults in moderate/severe FI presented almost three times more chance (OR 2.97; CI95% 1.37-6.44) of having malnutrition compared with those in food security. Conclusions: The study indicates that there is an association between household FI and malnutrition/risk of malnutrition among older adults from the FHS, especially among those in severe FI. This result attributes to FI the status of determinant of malnutrition in older adults within the context investigated.
