To compare the obstetric complications and mode of delivery between adolescent pregnancies and pregnancies of women over 20 years.
A prospective study of all pregnant mothers delivered at General Hospital, Anuradhapura during a period of two years from January 1993.
1600 pregnant adolescents and 14699 pregnant women over 20 years.
The percentage of adolescent pregnancies during this period was 9.8%. The incidence of pregnancy induced hypertension among adolescent women was 2.3% and 2.2% in women over 20 years. The still birth rate was 2.4% in adolescent pregnancies and 2.2% in women over 20 years. The incidence of breech presentation was 2.2% in both groups. There was a statistically significant difference (P < 0.001) in the incidence of low birth weight among live births between adolescents (33.6%) and women over 20 years (22.7%). Adolescent women had a caesarean section rate of 7% and a forceps delivery rate of 2.3% compared to 11.4% and 2.0% in mothers over 20 years, a statistically significant difference.
Adolescent women were not at an increased risk for pregnancy induced hypertension, still birth or breech presentation. The incidence of low birth weight and normal vaginal delivery were significantly higher among adolescent women.
比较青少年妊娠与20岁以上女性妊娠的产科并发症及分娩方式。
对1993年1月起两年间在阿努拉德普勒总医院分娩的所有孕妇进行前瞻性研究。
1600名青少年孕妇和14699名20岁以上的孕妇。
在此期间青少年妊娠的比例为9.8%。青少年女性妊娠高血压的发生率为2.3%，20岁以上女性为2.2%。青少年妊娠的死产率为2.4%，20岁以上女性为2.2%。两组臀位产的发生率均为2.2%。青少年（33.6%）与20岁以上女性（22.7%）活产儿中低出生体重的发生率存在统计学显著差异（P<0.001）。青少年女性剖宫产率为7%，产钳助产率为2.3%，而20岁以上母亲分别为11.4%和2.0%，存在统计学显著差异。
青少年女性发生妊娠高血压、死产或臀位产的风险并未增加。青少年女性低出生体重和正常阴道分娩的发生率显著更高。
