Abstract

Introduction: preterm birth is considered an indicator of perinatal morbidity and mortality.
Objective: to identify the risk factors associated with preterm birth in the health area of the “Ramón López Peña” Teaching Polyclinic, in Santiago de Cuba.
Methods: a case-control observational analytical study was carried out. The study population consisted of 84 mothers and the sample, defined in a 1:3 ratio by cases (pregnant women with deliveries before 37 gestational weeks, 21) and controls (pregnant women with deliveries at or more than 37 gestational weeks, 63), selected by simple random sampling. The odd ratio, confidence interval, Chi-square test and attributable risk in percentage exposed were determined.
Results: there was a significant causal association between preterm birth and urinary infection with odds ratio values of 4.70; gestational hypertension (4.58), unfavorable socio-environmental situation (4.50), insufficient maternal weight gain (4.29) and vaginal infection and nutritional evaluation of poor weight at intake with odd ratio values of 3.76 respectively.
Conclusions: the nutritional evaluation of poor weight at the time of pregnancy and insufficient weight gain, unfavorable socioeconomic situation and pregnancy-related diseases were the risk factors associated with the occurrence of preterm birth in the healthy study area.
