A short birth interval adversely affects the health of mothers and children. This study aimed to measure the prevalence of short birth intervals and identify their associated factors in a semi-urban setting in Burkina Faso.
We conducted a cross-sectional study in which data were collected in households between May and October 2022. The dependent variable was the short birth interval (SBI), defined by the World Health Organization as the time between two live births. We performed a multilevel mixed-effects Poisson regression with robust variance to determine the factors associated with the SBI by reporting adjusted prevalence ratios (aPR) with a 95% confidence interval (CI).
A total of 5544 birth intervals were recorded from 4067 women. A short birth interval was found in 1503 cases out of 5544, i.e., a frequency of 27.1%. The prevalence of short birth interval (time between two live births less than 33 months) was higher in never users of modern contraceptive users (aPR = 1.24; 95% CI [1.14-1.34] vs. previous users), in younger ages with aPR of 4.21 (95% CI [3.30-5.37]), 2.47 (95% CI [1.96-3.11]), and 1.45 (95% CI [1.16-1.81]), respectively for under 18, 18-24 years old, and 25-34 years old, compared to 35 and over. Childbirths occurring before the implementation of the maternal and infant free health care policy (aPR = 2.13; 95% CI [1.98-2.30]) and also before the free family planning policy (aPR = 1.53; 95% CI [1.28-1.81]) were more likely to have SBI. Women with low socio-economic positions were also more likely to have SBI.
This study found a high SBI in Burkina Faso (more than one woman out of four). Our results have programmatic implications, as some factors, such as contraceptive practice and socioeconomic status, are modifiable. These factors need particular attention to lengthen birth intervals and, in turn, improve mother-child couple health by reducing short birth interval consequences.
短生育间隔对母亲和儿童的健康有不利影响。本研究旨在测量布基纳法索半城市地区短生育间隔的患病率，并确定其相关因素。
我们进行了一项横断面研究，于2022年5月至10月期间在家庭中收集数据。因变量是短生育间隔（SBI），世界卫生组织将其定义为两次活产之间的时间。我们进行了具有稳健方差的多水平混合效应泊松回归，通过报告调整患病率比（aPR）及95%置信区间（CI）来确定与SBI相关的因素。
共记录了来自4067名女性的5544个生育间隔。在5544个案例中，发现1503例存在短生育间隔，即发生率为27.1%。从未使用过现代避孕方法的人群中短生育间隔（两次活产之间的时间少于33个月）的患病率高于曾经使用者（aPR = 1.24；95% CI [1.14 - 1.34]），年龄较小者的aPR分别为4.21（95% CI [3.30 - 5.37]）、2.47（95% CI [1.96 - 3.11]）和1.45（95% CI [1.16 - 1.81]），分别对应18岁以下、18 - 24岁和25 - 34岁，而35岁及以上者与之相比。在母婴免费医疗政策实施之前发生的分娩（aPR = 2.13；95% CI [1.98 - 2.30]）以及在免费计划生育政策实施之前发生的分娩（aPR = 1.53；95% CI [1.28 - 1.81]）更有可能出现短生育间隔。社会经济地位较低的女性也更有可能出现短生育间隔。
本研究发现布基纳法索的短生育间隔患病率较高（超过四分之一的女性）。我们的研究结果具有项目意义，因为一些因素，如避孕措施的使用和社会经济地位是可以改变的。这些因素需要特别关注，以延长生育间隔，进而通过减少短生育间隔的后果来改善母婴健康。
