Prevalência de prematuridade e fatores associados no estado do Rio Grande do Sul

Objective This article aims to study the prevalence of prematurity in the state of Rio Grande do Sul, taking into account the possible associated factors such as behavioral, sociodemographic and health. Materials and methods The study carried out a crosssectional design based on secondary data from the Live Birth Information System (SINASC), having as study population all live births in Brazil in 2014. Results: In short, we found in In our study, the prevalence of prematurity in the State of Rio Grande do Sul was 11.46% and was associated with maternal age ≥40 (PR = 1.29; CI = 1.20-1.40) for those born by cesarean section (PR = 1.14; CI = 1.10-1.17), the color of yellow, brown and indigenous mother (PR = 1.06; CI = 1.01-1.11) and widowed or separated mothers (PR = 1.06; CI = 0.95-1.19). We found as protection factor the mothers aged 20-29 years (PR = 0.89; CI = 0.85-0.93), those with higher education (PR = 0.80; CI = 0.740.88) and those who attended> 7 antenatal consultations (PR = 0.32; CI = 0.31-0.34). Conclusion: It is possible to infer that prematurity is a delicate and fundamentally important problem. associated with some variables such as low number of prenatal consultations, low education and high age of the mother. However, when related to variables such as gender of the newborn, skin color and marital status of the mother, the number of premature births did not show significant variation. Given the variables directly related to the high number of preterm infants, it is possible to change this situation with some measures that involve mothers' awareness of the importance of prenatal consultation, educational measures designed to prevent the high number of school dropouts and also policies aimed at reducing the number of caesarean deliveries. In this sense, it is important to highlight how important prenatal consultation is to reduce the number of premature newborns, given that the greater the number of consultations performed, the greater the protection factor provided, according to the present study. .
