Nutritional status coverage trend registered in the SISVAN web in sevenmunicipalities of the Zona Da Mata Mineira, Brazil, from 2008 to 2017, andits association with socio-economic, demographic and organisation ofhealth system variables

Abstract

We analysed the coverage trend of the evaluation of the nutritional status of users of public health services registered in the Food and Nutrition SurveillanceSystem (SISVAN) between 2008 and 2017 in seven municipalities and verified the association of the coverage trend with the socio-economic, demographic andorganisational aspects of health system variables. It is an ecological time-series study performed with secondary data extracted from health information systems.Descriptive statistics, linear regression model and repeated measures analysis were performed. The coverage of evaluation of nutritional status was low over theperiod. Five municipalities showed a tendency to increase coverage, although small, while two remained stable. The highest annual variation in coverage increasewas concentrated in the group of pregnant women and the lowest in adolescents and older adults. There was a downward trend in follow-ups from the BolsaFamily Programme and a trend towards increased follow-ups from SUS Primary Care (e-SUS AB). SISVAN coverage was positively associated with the pro-portion of rural population (P≤0·001) and coverage of community health agents (P<0·001); and negatively associated with total population (P<0·001),demographic density (P=0·006) and gross domestic product per capita (P=0·008). Despite the tendency to increase coverage in some municipalities,SISVAN still presents low coverage of nutritional status assessment, which compromises population monitoring. Knowing the factors that influence the cover-age can subsidise the elaboration of strategies for its expansion.
