Cobertura do estado nutricional da população registrada no sistema de vigilância alimentar e nutricional da região oeste mato-grossense

Abstract

Food and nutrition surveillance (VAN) has been recommended by international organizations since the 1970s. In Brazil, however, it has been implemented after the consolidation of the Unified Health System (SUS). The aim of this study is to describe and analyze the nutritional status of the population using primary care in the West Mato Grosso health region registered in the Web Food and Nutritional Surveillance System (SISVAN) between 2008 and 2017. The method used was a study was cross-sectional, retrospective, ecological of time series, with secondary data collection, having as unit of analysis the Western Mato Grosso Health Region, the indicators used were: percentage of nutritional status coverage for all municipalities in the Western region and phases of the course of life. The statistical analysis was performed by linear regression to estimate the temporal variation and Pearson's correlation between the percentage of total coverage of SISVAN Web in relation to socioeconomic and health characteristics. Between 2008 and 2017 it was observed that all municipalities presented nutritional status records in SISVAN Web and a trend of significant coverage increase was observed in 08 of the 12 municipalities that make up the health region. The average regional coverage ranged from 9.0% in 2011 to 20.5% in 2017. Monthly per capita income and MHDI were inversely correlated with coverage of nutritional status monitoring, while poverty percentage and FS coverage were positively correlated. Regarding stratification by phases of the course of life, a significant trend of increased coverage was observed in all phases, the highest volume of registration was observed in children. The results point to a still low coverage for a system that is intended to be universal, but with a significant tendency to increase between municipalities and in all phases of the life course.
