Differences in socio-economic status, service utilization, and pregnancy outcomes between teenage and adult mothers.
BACKGROUND
Teenage pregnancies put mothers at high-risks to many health-related complications and newborn infants to poor birth-outcomes.


OBJECTIVE
The present study aimed to explore the relationship of socio-economic status, service utilization, and pregnancy outcomes between teenage and adult mothers.


METHODS
The study design was a population-based prospective cohort study conducted in four districts located in different geographical areas of Thailand All pregnancies occurring within one year, in each of the selected districts as of October 2000, were identified and recruited as the study's cohorts. Data was collected by interviewing cohort-respondents and through reviewing medical records.


RESULTS
The present study showed that teenage pregnancies accounted for 13.3% of all pregnancies in the study area. Approximately two thirds of the teenage cohort (i.e. 68.8%) were 18-19 years of age, while the remaining cohort members were 14-17 years of age (i.e. 26.1% aged 16-17 years, and 5.1% aged 14-15 years). The percentage of low-birth weights for teenage and adult mothers were 15.1% and 8.8% respectively. A higher percentage of teenage mothers enrolled in or completed secondary or higher levels of education has had more abnormal deliveries in comparison with adult mothers. In comparison with the non-teenage mothers, a greater proportion of teenage mothers had insufficient income, did not own their homes/houses, were single parents, had fewer consultations with health personnel, did not plan their pregnancy, were pregnant for the first time, and delivered infants with low-birth weights.


CONCLUSIONS
The prevalence of teenage pregnancies in Thailand remains high. Most teenage mothers and their newborn infants are vulnerable to a variety of potentially serious health problems, and accordingly need appropriate help and support.
