Coverage of the Food and Nutrition Surveillance System (SISVAN), nutritional status of the elderly and its relationship with social inequalities in Brazil, 2008-2019: an ecological time series study

Abstract

Objective: To analyze the temporal trend in the coverage of the Food and Nutrition Surveillance System (SISVAN) and the nutritional status of the elderly, correlating them with indicators of social inequality. Methods: Ecological study using SISVAN records of the population aged ≥60 years. Correlation analyzes were performed between indicators of social inequality and the rate of increase in nutritional status and analyzes of absolute and relative inequalities to obtain the angular inequality index and the concentration index. Results: 11,587,933 records were identified. National coverage evolved from 0.1% in 2008 to 2.9% in 2019, with a statistically significant upward trend. A moderate inverse correlation was found with the annual increase rate of overweight for HDI and per capita GDP. Conclusion: There was a trend of growth in SISVAN coverage. The increase in overweight was associated with social inequality.
