This study aimed to evaluate the impact of Ghana's free maternal health care policy on stillbirth and perinatal death since its implementation a decade ago.
The study used the propensity score matching method, a quasi-experimental design technique and secondary data to construct two groups of mothers with a history of perinatal deaths who subscribed to the 'free' maternal health care policy versus mothers who did not.
The study merged two rounds of repeated cross-sectional data sets obtained from the Ghana Demographic and Health Survey (GDHS), 2008 and 2014, and generated exposure variables; pregnant women policy holding status and outcome variables; stillbirth and perinatal death by constructing binary outcomes from the under-five mortality variables of the DHS data sets. Fetal and early neonatal deaths within the data set were categorized into two groups: those exposed to the free maternal health care policy and those who did not. The propensity scores of the two groups were then generated and analyzed after checking for bias and common support. The analysis applied sample weighting to account for clustering and stratification due to the complex design of the DHS. All analyses were done with STATA 15 and adjusted for confounding using independent covariates.
Stillbirth (43.3%) and perinatal death (60.2%) were high in the intervention group compared to the comparison group, and the differences were statistically significant (stillbirth, 0.0156, and perinatal death, 0.0012). Stillbirth and perinatal deaths were 12 and 13 percentage points higher in the intervention group, and these were statistically significant: adj. coef. = 0.12; 95% CI: [0.03-0.19]; P = 0.005 and adj. coef. = 0.13; 95% CI: [0.03-0.22]; P = 0.005.
The results show that stillbirth and perinatal death were high in the maternal health care policy group, poorly reflecting as outcomes. However, the percentage point difference between stillbirth and perinatal death suggests a decline in early neonatal mortality and a positive impact of the 'free' maternal health care policy on perinatal death over stillbirth.
本研究旨在评估加纳实施免费产妇保健政策十年来对死产和围产儿死亡的影响。
本研究采用倾向评分匹配法,一种准实验设计技术和二次数据,构建了两组有围产儿死亡史的母亲,一组是参加“免费”产妇保健政策的母亲,另一组是没有参加的母亲。
本研究合并了两次来自加纳人口与健康调查(GDHS)的重复横断面数据集,2008 年和 2014 年,并生成了暴露变量;孕妇政策持有状况和结果变量;通过从 DHS 数据集的五岁以下儿童死亡率变量中构建二项结果,得出死产和围产儿死亡。数据集内的胎儿和早期新生儿死亡分为两组:暴露于免费产妇保健政策的组和未暴露的组。然后生成两组的倾向评分,并在检查偏倚和共同支持后进行分析。分析采用样本加权,以弥补 DHS 复杂设计造成的聚类和分层。所有分析均采用 STATA 15 进行,并使用独立协变量调整混杂因素。
干预组的死产(43.3%)和围产儿死亡(60.2%)较高,差异具有统计学意义(死产,0.0156,围产儿死亡,0.0012)。干预组的死产和围产儿死亡分别高出 12 和 13 个百分点,差异具有统计学意义:调整后的系数=0.12;95%CI:[0.03-0.19];P=0.005 和调整后的系数=0.13;95%CI:[0.03-0.22];P=0.005。
结果表明,产妇保健政策组的死产和围产儿死亡较高,但作为结果反映不佳。然而,死产和围产儿死亡之间的百分点差异表明,早期新生儿死亡率下降,“免费”产妇保健政策对围产儿死亡的影响好于死产。
