This study explores birth outcomes and determinants in adolescent pregnancies, using subjects drawn from the Taiwan Birth Cohort Study (TBCS) from 2005.
Through completed interviews and surveys with mothers or other family members, differences in birth outcomes and personal, pregnancy and social profiles of mothers were analyzed.
A total of 533 adolescent mothers (<20 years old) and 9347 adult mothers (20-34 years old) were included in our study. There was a significantly higher incidence of low birthweight (LBW) (<2500 g, 10.2% vs 5.6%) and premature birth (<37 weeks, 14.8% vs 8.6%) in the adolescent group. When adjusted for covariates in the multiple-variable model, youth remained a risk factor for LBW (OR = 1.50, 95%CI 1.09, 2.07) and premature delivery (OR = 1.42, 95%CI 1.07, 1.89). Age, prenatal care and weight gain during pregnancy are important predictors of LBW and premature birth.
Adolescent pregnancy carries a high-risk of LBW and premature birth. Inadequate prenatal care and weight gain during pregnancy are contributing factors that could be improved through strategies of health education, family support and case management.
本研究利用2005年台湾出生队列研究（TBCS）中的研究对象，探讨青少年怀孕的分娩结局及其决定因素。
通过对母亲或其他家庭成员进行完整的访谈和调查，分析分娩结局以及母亲个人、怀孕和社会特征方面的差异。
本研究共纳入533名青少年母亲（<20岁）和9347名成年母亲（20 - 34岁）。青少年组低出生体重（<2500 g，10.2%对5.6%）和早产（<37周，14.8%对8.6%）的发生率显著更高。在多变量模型中对协变量进行调整后，年轻仍然是低出生体重（OR = 1.50，95%CI 1.09，2.07）和早产（OR = 1.42，95%CI 1.07，1.89）的一个危险因素。年龄、产前护理和孕期体重增加是低出生体重和早产的重要预测因素。
青少年怀孕有高风险导致低出生体重和早产。产前护理不足和孕期体重增加是促成因素，可以通过健康教育、家庭支持和病例管理策略加以改善。
