ANALYSIS OF THE SITUATION OF CONGENITAL SYPHILIS IN THE NORTHERN MACRO-REGION OF RIO GRANDE DO SUL: A STUDY OF A DECADE IN CHILDREN UNDER ONE YEAR OF AGE

Abstract

Objective: to analyze the situation of the incidence of congenital syphilis (CS) in the Northern Macro-region of the state of Rio Grande do Sul (RS) from January 2010 to December 2019 and what are the main associated sociodemographic and clinical factors. Methodology: ecological time series study conducted with 837 cases of CS with data from the Notifiable Diseases Information System of the Ministry of Health (SINAN). The mean annual incidence rate of CS and the following variables were analyzed: gender, age group, skin color, final classification, and evolution. Temporal trend analyses were performed using the Prais-Winsten model. Results: The mean incidence rate and temporal trend of CS in children under one year of age was 5.62 cases per 1,000 children in the North Macro-region, with the highest rate in R17-Planalto, with 12.22 cases per 1,000 children. All the Health Regions of Macronorte showed an increasing trend, except for R19-Botucaraí, which showed a stationary trend. Municipalities with larger populations and lower coverage of Primary Health Care (PHC) had a higher incidence of CS, probably due to difficulties in ensuring access to prenatal and postpartum care. Conclusion Since CS is a sentinel event of the quality of care in the maternal and child care line, these results can guide decision-making based on epidemiological indicators, optimizing resources and ensuring compliance with the goals established by the Sustainable Development Goals/2030 Agenda.
