Teenage pregnancy may adversely affect their health, economic, and social life. Evidence shows that no studies in Ethiopia used decomposition analysis to identify factors for the trend change in teen pregnancy. Therefore, this study aimed to examine the trends and identify contributing factors to teen pregnancy in Ethiopia using multivariate decomposition analysis.
We obtained the data on adolescent women from three Ethiopian Demographic and Health Surveys. A weighted sample of 3266 in 2005, 4009 in 2011, and 3381 teenagers in 2016 were involved in this study. Statistical analysis was performed using STATA 14. Multivariate decomposition analysis was used to identify contributing factors to the change in teen pregnancy. The coefficient value with a 95% confidence interval was used to identify significant factors associated with teen pregnancy.
The prevalence of teen pregnancy in Ethiopia decreased significantly from 15.9% [95% CI: 14.3, 17.7] in 2005 to 12.5% [95% CI: 10.8, 14.3] in 2016. Multivariate decomposition analysis showed that approximately 83% of the overall change in teen pregnancy over time was due to differences in women's composition. Age, marital status, education status, working status, contraceptive use, and sexual status before age 18 were statistically significant contributing factors to the decline in teen pregnancy over time.
The prevalence of teen pregnancy in Ethiopia decreased significantly over time. The overall decline in teenage pregnancy is due to differences in population composition. Public health interventions should focus on changing cultural norms or attitudes regarding early marriage and pregnancy within religious leaders and uneducated communities.
少女怀孕可能会对她们的健康、经济和社会生活产生不利影响。有证据表明，在埃塞俄比亚，尚无研究采用分解分析法来确定少女怀孕趋势变化的因素。因此，本研究旨在利用多元分解分析法来研究埃塞俄比亚少女怀孕的趋势，并确定导致少女怀孕的因素。
我们从三次埃塞俄比亚人口与健康调查中获取了少女的数据。在 2005 年、2011 年和 2016 年，分别有 3266 名、4009 名和 3381 名青少年参加了这项研究。采用 STATA14 进行统计分析。采用多元分解分析法来确定少女怀孕变化的影响因素。采用 95%置信区间的系数值来确定与少女怀孕相关的显著因素。
埃塞俄比亚少女怀孕的发生率从 2005 年的 15.9%（95%CI：14.3，17.7）显著下降到 2016 年的 12.5%（95%CI：10.8，14.3）。多元分解分析表明，少女怀孕总体变化的约 83%归因于妇女构成的差异。年龄、婚姻状况、教育状况、工作状况、避孕措施和 18 岁之前的性行为是导致少女怀孕随时间下降的统计学显著因素。
埃塞俄比亚少女怀孕的发生率随时间显著下降。少女怀孕的总体下降归因于人口构成的差异。公共卫生干预措施应侧重于改变宗教领袖和未受教育社区中关于早婚和早孕的文化规范或态度。
