According to the World Health Organization and Ethiopian Demographic and Health Survey on birth spacing, there should be at least a two-year gap between conception and the first of two children born in quick succession. In poor nations like Ethiopia, resource issues were complex, making it difficult to get statistics for the entire country. However, by examining Ethiopian mini demographic and health survey data, we were able to provide data at the national level.
The cross-sectional survey-based study was conducted in several of Ethiopia's administrative cities and nine regions. In the analysis, sampling weight was used to correct the survey's non-proportional sample distribution to strata and areas throughout the survey process and restore representative data. The study's household population was presented and described using descriptive statistics such as weighted frequencies and percentages. The statistically significant factors linked to frequent short birth intervals were found using a multivariable, multilevel logistic regression analysis.
Overall, 4306 weighted multigravida mothers nested within 305 enumeration areas were included in the analysis. The respondents' mean (standard deviation) of the birth interval was 42.027(26.69). Higher-educated women had 12% lower odds of having a shorter pregnancy (AOR = 0.88; 95% CI: 0.35, 0.98) than women without higher education. The odds of a short birth interval were 3.04 times greater among women in the age category of 40-49 years at first marriage (AOR = 3.04; 95% CI: 1.08, 8.46) than among women in the age category of 15-19 years. This indicates that older women were most likely to have short birth intervals.
In the multilevel logistic regression model, maternal age, maternal educational status, the wealth quintile index, use of contraceptives, duration of breastfeeding, and contextual regions were significantly associated with short birth intervals in Ethiopia.
根据世界卫生组织和埃塞俄比亚人口与健康调查，两次生育之间至少应该间隔两年。在埃塞俄比亚等贫穷国家，资源问题复杂，难以获得全国范围的统计数据。然而，通过检查埃塞俄比亚小型人口与健康调查数据，我们能够提供国家层面的数据。
这项基于横断面调查的研究在埃塞俄比亚的几个行政城市和九个地区进行。在分析中，使用抽样权重来纠正调查中非比例样本分配到各层和各地区的问题，并恢复代表性数据。研究中的家庭人口通过描述性统计（如加权频率和百分比）进行呈现和描述。使用多变量、多层次逻辑回归分析发现与频繁短生育间隔相关的统计学显著因素。
总体而言，有 4306 名加权多产妇嵌套在 305 个计数区中进行了分析。受访者生育间隔的平均值（标准差）为 42.027（26.69）。受过高等教育的女性生育间隔较短的可能性比没有接受过高等教育的女性低 12%（AOR=0.88；95%CI：0.35，0.98）。首次结婚年龄在 40-49 岁的女性生育间隔较短的可能性是 15-19 岁女性的 3.04 倍（AOR=3.04；95%CI：1.08，8.46）。这表明年龄较大的女性更有可能生育间隔较短。
在多层次逻辑回归模型中，母亲年龄、母亲教育程度、财富五分位数指数、避孕药具使用、母乳喂养持续时间和上下文区域与埃塞俄比亚的短生育间隔显著相关。
