Abstract
Objective: to analyze the temporal trend of Food and Nutrition Surveillance System (Sistema de Vigilância Alimentar e Nutricional - SISVAN) coverage and the nutritional status of older adults, and its correlation with indicators of social inequality in Brazil between 2008-2019.
Methods: this was an ecological study using records from SISVAN, related to the population aged 60 years and older; the temporal trend of coverage and the correlation between indicators of social inequality and increment rate of nutritional status were analyzed; slope index of inequality and concentration index were used to measure absolute and relative inequalities.
Results: 11,587,933 records were identified; national coverage increased from 0.1% (2008) to 2.9% (2019), with a statistically significant upward trend; a moderate inverse correlation with an annual increment rate of overweight between human development index and gross domestic product per capita, was found.
Conclusion: there was an increasing trend in SISVAN coverage; the increase in overweight was associated with social inequality.
目的：分析2008-2019年巴西食品和营养监测系统（Sistema de Vigilância Alimental e Nutricional-SISVAN）覆盖率和老年人营养状况的时间趋势，及其与社会不平等指标的相关性；分析了覆盖率的时间趋势以及社会不平等指标与营养状况增长率的相关性；不等式的斜率指数和集中度指数用于度量绝对不等式和相对不等式。结果：共鉴定出11587933条记录；全国覆盖率从0.1%（2008年）增加到2.9%（2019年），具有统计学上显著的上升趋势；人类发展指数和人均国内生产总值与超重年增长率呈中度负相关。结论：SISVAN覆盖率呈上升趋势；超重的增加与社会不平等有关。
