The global burden of malaria has reduced considerably; however, malaria in pregnancy remains a major public health problem in sub-Saharan Africa (SSA), where about 32 million pregnant women are at risk of acquiring malaria. The WHO has recommended that pregnant women in high malaria transmission locations, including SSA, have intermittent preventive treatment of malaria during pregnancy with at least three doses of sulphadoxine-pyrimethamine (IPTp-SP). Therefore, we investigated the prevalence of IPTp-SP uptake and associated individual-level, community-level and country-level predictors in SSA.
A cross-sectional survey was conducted using recent Demographic and Health Surveys datasets of 20 SSA countries. A total of 96 765 women were included. Optimum uptake of IPTp-SP at most recent pregnancy was the outcome variable. We fitted three-level multilevel models: individual, community and country parameters at 95% credible interval.
In all, 29.2% of the women had optimal IPTp-SP uptake ranging from 55.1% (in Zambia) to 6.9% (in Gambia). The study revealed a high likelihood of optimum IPTp-SP uptake among women with high knowledge (aOR=1.298, Crl 1.206 to 1.398) relative to women with low knowledge. Women in upper-middle-income countries were more than three times likely to have at least three IPTp-SP doses compared with those in low-income countries (aOR=3.268, Crl 2.392 to 4.098). We found that community (σ=1.999, Crl 1.088 to 2.231) and country (σ=1.853, Crl 1.213 to 2.831) level variations exist in optimal uptake of IPTp-SP. According to the intracluster correlation, 53.9% and 25.9% of the variation in optimum IPTp-SP uptake are correspondingly attributable to community-level and country-level factors.
The outcome of our study suggests that low-income SSA countries should increase budgetary allocation to maternal health, particularly for IPTp-SP interventions. IPTp-SP advocacy behavioural change communication strategies must focus on women with low knowledge, rural dwellers, married women and those who do not meet the minimum of eight antenatal care visits.
全球疟疾负担已大幅减轻;然而,妊娠疟疾仍是撒哈拉以南非洲(SSA)的一个主要公共卫生问题,那里约有 3200 万孕妇有感染疟疾的风险。世界卫生组织(WHO)建议,包括 SSA 在内的疟疾高传播地区的孕妇在妊娠期间应进行间歇性预防治疗疟疾,至少服用三剂磺胺多辛-乙胺嘧啶(IPTp-SP)。因此,我们调查了 SSA 中 IPTp-SP 接种的流行情况以及与个体、社区和国家层面相关的预测因素。
使用最近的 20 个 SSA 国家的人口与健康调查数据集进行了横断面调查。共纳入了 96765 名妇女。最近一次妊娠中 IPTp-SP 最佳接种情况是因变量。我们拟合了三水平多水平模型:个体、社区和国家参数的 95%可信区间。
在所有妇女中,有 29.2%的妇女接受了最佳的 IPTp-SP 接种,范围从 55.1%(赞比亚)到 6.9%(冈比亚)。研究表明,与知识水平较低的妇女相比,知识水平较高的妇女(OR=1.298,Crl 1.206-1.398)更有可能接受最佳的 IPTp-SP 接种。与低收入国家相比,中上收入国家的妇女更有可能至少接受三次 IPTp-SP 剂量(OR=3.268,Crl 2.392-4.098)。我们发现,社区(σ=1.999,Crl 1.088-2.231)和国家(σ=1.853,Crl 1.213-2.831)层面存在 IPTp-SP 最佳接种的差异。根据聚类相关系数,最佳 IPTp-SP 接种的变异有 53.9%和 25.9%分别归因于社区和国家层面的因素。
我们的研究结果表明,低收入 SSA 国家应增加对孕产妇保健的预算分配,特别是对 IPTp-SP 干预措施的分配。IPTp-SP 宣传行为改变沟通策略必须侧重于知识水平较低的妇女、农村居民、已婚妇女和未达到最低 8 次产前护理就诊次数的妇女。
