背景在撒哈拉沙漠以南的非洲，关于青春期重复生育的信息仍然很少。我们调查了乌干达青春期重复生育的患病率和时间趋势，以及相关因素。方法我们分析了乌干达人口与健康调查中收集的6次调查(1988年/1989年至2016年)20-24岁女性的数据，以估计重复青春期生育(第一次活产和18岁，第二次活产(S)和20岁)。此外，我们估计了第二次出生的需求和第一次和第二次这样的出生之间短出生间隔(<；13个月)的发生率。在2016年的调查中，我们使用双变量和多变量改进的泊松回归分析了与青春期重复生育相关的因素。结果在1988/89年的调查中，58.9%的第一次生育和18岁以下的女性报告重复青春期生育。这一百分比在2006年上升到66.8%(+7.9%[pp]，p=0.010)，此后下降到2016年的55.6%(-11.2pp，p<；0.001)，然而，1988年至1989年与2016年(-3.3pp，p=0.251)之间没有变化。在重复出生的青春期妇女中，按确切年龄计算的平均活产数(2.2次出生)和短生育间隔的发生率(1988/89年为3.5%，2016年为5.4%)(+1.9 pp，p=0.245)没有变化。越来越多的青春期重复生育的女性倾向于晚育，1995年和2016年分别为22.5%和43.1%(+20.6pp，p=
BackgroundInformation on repeat adolescent birth remains scarce in sub-Sahara Africa. We investigated the prevalence and time trends in repeat adolescent birth in Uganda, and associated factors.MethodsWe analyzed Uganda Demographic and Health Survey data of women age 20-24 years collected on 6 surveys (1988/89-2016) to estimate repeat adolescent birth (first live birth < 18 years of age followed by another live birth(s) < 20 years). Further, we estimated the wantedness of the second order birth and the prevalence of short birth intervals birth (< 13 months) between the first and second such birth. On the 2016 survey, we examined factors associated with repeat adolescent birth using bivariate and multivariate modified Poisson regression.ResultsAt the 1988/89 survey, 58.9% of women with first birth < 18 years reported a repeat adolescent birth. This percentage increased to 66.8% in 2006 (+7.9 percentage points [pp], p = 0.010) and thereafter declined to 55.6% by 2016 (-11.2 pp, p < 0.001), nevertheless, no change occurred between 1988/89 and 2016 (-3.3pp, p = 0.251). Among women with repeat adolescent births, the mean number of live births by exact age 20 years (2.2 births) and prevalence of short birth intervals (3.5% in 1988/89, 5.4% in 2016) (+1.9pp, p = 0.245) did not change. Increasingly more women with repeat adolescent births preferred to have had the second child later, 22.5% in 1995 and 43.1% in 2016 (+20.6pp, p =
