Exploring the Risks of Repeated Pregnancy Among Adolescents and Young Women in the Philippines

Objective Knowledge of the factors which influence repeat pregnancy can inform much needed evidence-based prevention programs. This study aims to identify correlates of repeat pregnancy in the Philippines. Methods We used data from five Philippine Demographic and Health Surveys (1993-2013). A total of 4757 women 15-24 years old who had experienced ≥ 1 pregnancy were included. Individual and partner-related factors were fitted into a series of logistic regression stepwise models with deformalized survey weights. Stratified analyses using two age groups (15-19, 20-24) were also conducted. Interaction terms were included to test for statistical differences between the groups. Results Lower wealth quintiles [odds ratio (OR) 1.71, 95% confidence interval (CI) 1.17-2.49] and partner characteristics such as age of ≥ 30 years (OR = 1.99, CI = 1.41-2.82), multiple partners (OR = 4.19, CI = 1.57-11.19) and live-in status (OR = 1.38, CI = 1.02-1.87) were found to be highly correlated with repeat pregnancy in fully adjusted analysis. Receiving prenatal care from traditional healers (OR = 1.93, CI = 1.02-3.63) during the first pregnancy and giving birth for the first time before 18 years of age (OR = 1.12, CI = 1.04-1.20) showed increased risks among 15-19 years old compared to 20-24 years old in stratified analysis. Conclusions for practice In general, partner characteristics were associated with repeat pregnancy among young women suggesting male involvement, especially older partners, in family planning. High risks for repeat pregnancy were observed among adolescent women who reported younger age at first birth and received prenatal care from a traditional healer which entail promotion of trained prenatal care. Further analysis is needed to validate these findings in other developing countries.

Factors That Affect Perinatal Outcomes of the Second Pregnancy of Adolescents

STUDY OBJECTIVE

We assessed factors that might affect perinatal outcomes in second pregnancies in adolescents. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, MAIN OUTCOME MEASURES: This longitudinal retrospective study was carried out on 66 adolescents who experienced 2 deliveries during their adolescence. Data were collected for the first and second pregnancies. Odds ratios (ORs) and 95% confidence intervals (CIs) for adverse perinatal outcomes in the second pregnancy were calculated using a logistic regression model and SPSS software (version 17.0 for Windows; SPSS Inc, Chicago, IL). A P value < .05 was considered to indicate statistical significance.

RESULTS

Body mass index, number of antenatal care visits, weight gain during pregnancy, incidence of anemia, smoking status, gestational week at delivery, cesarean section rate, and birth weight were similar between the first and second pregnancies of these adolescents. Neonatal intensive care unit admission rate, preeclampsia rate, low neonatal birth weight rate, and 5-minute Apgar scores <7 were significantly higher in the first than in the second pregnancy (P < .001). Age of 16 years or younger at the time of first pregnancy (OR = 1.5; 95% CI, 0.9-2.1; P < .01), less than an 18-month interval between births (OR = 1.4; 95% CI, 0.2-1.7; P < .04), presence of gestational complications in the first pregnancy (OR = 1.9; 95% CI, 1.0-3.4; P < .01), and the presence of perinatal complications in the first pregnancy (OR = 1.3; 95% CI, 1.0-1.9; P < .01) were found to be significant indicators for adverse neonatal outcomes in second pregnancies of adolescents.

CONCLUSION

We found that the second pregnancies of adolescents were associated with fewer adverse perinatal outcomes than were their first pregnancies. However, some factors regarding the presence of perinatal complications in the first pregnancy, such as maternal age of 16 years or younger at the time of the first pregnancy and interval between first and second pregnancy of less than 18 months, were found to increase the risk of adverse perinatal outcomes for the second births.
