Factors associated with first trimester period absence from prenatal control in pregnant women from ESE San Sebastian in La Plata, Huila, 2009

Abstract

It is an analytical study of cases and controls based on medical records review of pregnant women from the prenatal program who attended before and after the first trimester of pregnancy from September to December 2009 at San Sebastian Hospital in La Plata - Huila. This research aim is to determine the factors associated with no prenatal care during the first trimester period. It was studied a group of 139 cases of pregnant women with late onset of prenatal care and 149 controls. Univariate and bivariate analysis was made using SPSS version 19 for Windows. To estimate the risk of prenatal control late onset associated with risk factors, the odds ratio (OR) was calculated, and confidence intervals (CI) were calculated at 95%. In the results, the ages of the 288 pregnant women attending antenatal care ranged between 14 and 45.77.1% of pregnant women received the government's benefit. Educational level higher than primary education is a protective factor, statistically significant for those who managed to finish high school. ((OR=1, 85 CI 95%= 1, 05-3, 14 p=0,015). The risk of late onset of antenatal care increased as the number of pregnancies was higher, being the history of 4-6 pregnancies statistically significant (CI 95%: 1, 15-5, 52; p-value: 0,011). In conclusion, the main factors associated with onset of prenatal care after the first trimester period are teen pregnancy, low educational levels, and women with 4-6 previous pregnancies.
