Social support and food insecurity among older Brazilians in São Paulo

Abstract

Food insecurity is a growing problem in Brazil, especially among older adults; however, the related sociodemographic factors remain unclear. This study aimed to analyze the relationship between social support dimensions and food insecurity among community-dwelling older adult Brazilians in São Paulo. This cross-sectional study was conducted in three cities in Sao Paulo state, Brazil. The analysis included 598 community-dwelling individuals aged ≥60-years-old, and multiple logistic regression models were used to estimate the associations between the dimensions of social support and food insecurity after adjusting for sociodemographic characteristics. We found that 42.3% of participants were food insecure. In the bivariate analysis, the higher scores in the affective, material, positive social interaction, and informational social support dimensions were statistically associated with the lower odds of food insecurity. In the multiple regression analysis, older adults who had a higher score of positive social interaction were less likely to have food insecurity, whereas the African American ethnicity and those older adults with a total family income ≤2 times of the minimum wage were more likely to have food insecurity. The results indicate that the positive social interaction emerges as an important factor associated with food insecurity among older adults, beyond that of other well-known social factors associated with food insecurity, highlighting the importance of screening for food insecurity and social support in primary care to avoid potential adverse health outcomes among older adults.

Factors Associated to Dietary Diversity in Community-dwelling Brazilian Older Adults

“…In our study, social support was not signi cant in the nal model, despite being widely described in the literature as an important factor associated with better dietary quality in older people and lower likelihood of food insecurity [28][29][30][31][32] . A qualitative study that analyzed food choices and access to food among lowincome older adults pointed out that social interactions, especially with family and friends, can positively affect the eating behavior, increasing the consumption of healthier meals and decreasing the consumption of fast meals, such as toast and cereal 33 .…”
