Factors associated with screening for preeclampsia in the Democratic Republic of Congo: evidence from a nationwide cross-sectional study
Abstract BackgroundDelays in identification of women with preeclampsia is a contributing factor to maternal deaths in developing countries. We conducted this study to assess the prevalence of screening for preeclampsia in the Democratic Republic of Congo (DRC), and to identify factors associated with the screening. Methods We used data from the 2017-2018 DRC Service Provision Assessment survey, a nationwide survey that samples services, including antenatal care (ANC), in representative health facilities. A pregnant woman was deemed screened for preeclampsia if she had received the two following services: blood pressure measurement and assessment for warning signs of preeclampsia. We used multiple logistic regression, with generalized estimating equations, to identify factors associated with screening for preeclampsia.ResultsOf the 3763 pregnant women, 719 (19.1%; 95% CI, 15.8% – 22.9%) were screened for preeclampsia, 815 (21.7%; 95% CI, 18.2% - 25.6%) were assessed for preeclampsia-related warning signs and symptoms, and 2941 (78.2%; 95% CI 73.6 – 82.1%) had their blood pressure checked.In multivariable analyses, the percentage of women receiving screening for preeclampsia was significantly higher among women with a secondary level of schooling or above (adjusted odds ratio [AOR] = 1.21; 95% CI, 1.04-1.42; P=0.016) and among women having a subsequent ANC visit (AOR = 1.39; 95% CI, 1.20-1.62; P<0.001). It was also higher among women receiving care in facilities with a low number of women attended per day (AOR = 1.28; 95% CI, 1.09-1.51; P=0.003) and in urban settings (AOR = 1.36; 95% CI, 1.02-1.82; P=0.036). There was a regional variation in the screening for preeclampsia, with the lowest prevalence observed in the Central (10.7%) and the highest in the Eastern provinces (22.5%). ConclusionOur study shows that screening for preeclampsia during ANC visits in DRC is not systematic, with disparities between provinces. We found that a low schooling level, a low number of ANC visits, rural areas, province of residence, and a high volume of ANC visits at the facility were associated with a low screening for preeclampsia. These factors should be considered for setting up strategies in order to increase the screening for preeclampsia during ANC visits in provinces of DRC with too low screening.
