目的研究年轻产妇年龄对尼泊尔南部农村地区流产和死产的影响。方法在两项关于孕妇补充微量营养素的随机试验中，前瞻性地确定了妊娠、流产和死产。这项分析包括5861名胎次为0的妇女(未产妇)和4459名胎次为1的妇女(初产妇)，她们的年龄为26岁。结果在未分娩的妇女中，5.7%和4.6%的妊娠以流产和死产告终。与18岁和19岁相比，15岁女童流产的调整后相对危险度为2.07(95%可信区间=1.17-3.66)，15-17岁女童流产的调整后相对危险度为1.40(95%CI=1.06-1.84)。不同产妇年龄的死胎率没有显著差异。初产妇的流产或死胎率与产妇年龄无关。结论产妇年龄小会增加未产妇流产的风险，但不会增加死产。初产妇女的流产和死产没有因产妇年龄的不同而不同。
PURPOSETo examine the impact of young maternal age on miscarriages and stillbirths in rural Southern Nepal.METHODPregnancies, miscarriages, and stillbirths were prospectively identified in two randomized trials of maternal micronutrient supplementation. This analysis included 5861 women of parity 0 (nulliparas) and 4459 of parity 1 (primiparas) who were <26 years of age.RESULTSAmong nulliparous women, 5.7% and 4.6% of pregnancies ended in miscarriage and stillbirth. The adjusted relative risk of miscarriage was 2.07 for girls <15 (95% confidence interval [CI] = 1.17–3.66) compared with those 18 and 19 years, and was 1.40 (95% CI = 1.06–1.84) among those 15–17 years. Stillbirth rates did not differ significantly by maternal age. There were no differences in miscarriage or stillbirth rates by maternal age among primiparas.CONCLUSIONYoung maternal age increased the risk of miscarriages but not stillbirths for nulliparas. Miscarriages and stillbirths did not differ by maternal age for primiparous women.
