Comparison of maternal and foetal outcomes between adolescent and adult pregnancies; a descriptive cross sectional study

Introduction: Adolescent pregnancy is a global issue and the trend is increasing specially in South East Asia. Pregnancies at a younger age have major maternal and fetal health consequences. The aim of this study was to compare selected maternal and fetal outcomes of adolescent pregnancies with its adult counterpart in atertiary care center.

Methods: A hospital based descriptive study was conducted at Teaching Hospital Mahamodara (THM), Galle. One hundred adolescent mothers (10-19 years) were compared with 100 adult mothers (20 -35 years) who had singleton uncomplicated pregnancy. Pre-tested interviewer administered questionnaire was used as the tool to collect data on basic demography, perinatal, maternal outcomes and mode of delivery. Chi-squared test and t-test were used to compare data and presented as proportions, mean (SD), with 95% CI.

Results: Mean (SD) age at delivery of adolescent and adult mothers were 18 (0.2) and 27 (0.8) years respectively. Of the adolescent mothers 16% were unmarried. More adolescent mothers had anaemia compared to adults (38% vs. 32%), but the difference was not statistically significant (p=0.37). Adolescent mothers had higher pre term delivery rate compared to adult mothers (23% vs.15%) but the difference was not statistically significant (p=0.18). There were no significant differences in birth weight (2.77 vs. 2.82; p=0.5) rate of admissions to premature baby unit (6% vs. 7%; p=0.8) and mean APGAR scores (9.9 vs 9.8; p=0.3) between the two groups. A significantly greater proportion of vaginal deliveries were carried out in adolescents compared to adults (75% vs. 55%; p= 0.003).
