Abstract
The goal of this study was to determine the relationship between women's ages and their pregnancy outcomes. A retrospective cohort study examined data from 1,431 pregnant women who gave birth at Thoen Hospital Between 1 October 2017 - 28 February 2022. The women were divided into 4 age groups: < 20 years, 20-29 years, 30-39 years, and 40 years and older. Descriptive statistics such as percentage, mean, standard deviation (SD) and ANOVA, Kruskal-Wallis H Test, Independent T-Test, Mann-Whitney U Test, chi-square test and Fisher's Exact test were used. The study found that pregnant women age < 20 year had a lower rate of caesarean section, hypertension, and gestational diabetes but higher rates of HIV infection and low birth weight than other groups. In addition, this group had poor quality of antenatal care. Pregnant women aged 20-29 years were found to have the lowest rate of low birth weight babies, babies with birth asphyxia, and preterm birth amongst all of the age groups. Pregnant women aged 30-39 years had better access to prenatal care and the mean birth weight of their babies was higher than other groups, however, there were higher number of caesarean sections. In addition, abnormal presentation and macrosomia was found more often in this age group than in the others. Pregnant women aged 40 and older were shown to have the highest rate of pregnancy included hypertension, gestational diabetes, preterm labor, post term labor, and birth asphyxia than other groups. The analysis found that pregnant women aged 20-29 years had good overall pregnancy outcomes in several respects, recommending that pregnancy should be promoted during this age. There are several poor pregnancy outcomes for women aged 40 and older, which are not recommended for pregnancy. However, if a woman does get pregnant in this age group, they should be closely monitored.
