Despite the availability of effective preventive measures, including intermittent preventive treatment for malaria during pregnancy (IPTp), malaria continues to cause substantial disease burden among pregnant women in malaria-endemic areas. IPTp coverage remains low, despite high antenatal care (ANC) attendance. To highlight areas of potential improvement, trends in IPTp coverage were assessed over time, missed opportunities to deliver IPTp at ANC were quantified, and delivery of IPTp was compared to that of tetanus toxoid (TT).
Data from 58 Demographic and Health Surveys conducted between 2003 and 2013 in 31 sub-Saharan African countries, with relevant questions on IPTp, ANC and TT were used to assess ANC attendance, and IPTp and TT delivery. A missed opportunity for IPTp delivery is an ANC visit at which IPTp could have been delivered according to policy but was not.
The proportion of pregnant women who received ≥2 doses of IPTp increased in surveyed countries from nearly zero before to a median of 29.6% (IQR 20.1-42.5%) seven or more years after IPTp policy adoption. ANC attendance was high (median 76.6% reported ≥3 visits); however, even seven or more years post policy adoption, a median of 72.9% (IQR 58.4-79.5%) ANC visits were missed opportunities to deliver IPTp. Among primigravid women, a median of 61.5% (IQR 50.9-72.9%) received two doses of TT; delivery of recommended TT exceeded IPTp in all but one surveyed country.
IPTp coverage measured by household surveys is unsatisfactorily low, even many years after policy adoption. The many missed opportunities to deliver IPTp suggest that deficiencies in delivery at ANC are a significant contributing factor to the low coverage levels. High levels of TT delivery indicate capacity to deliver preventive measures at ANC. Further research is required to determine the factors driving the discrepancies between IPTp and TT coverage, and how these may be addressed to improve IPTp coverage.
尽管有包括孕期疟疾间歇性预防治疗(IPTp)在内的有效预防措施,但疟疾在疟疾流行地区的孕妇中仍造成大量疾病负担。尽管产前保健(ANC)就诊率很高,但IPTp覆盖率仍然很低。为了突出潜在的改进领域,评估了IPTp覆盖率随时间的变化趋势,量化了在ANC提供IPTp时错过的机会,并将IPTp的提供情况与破伤风类毒素(TT)的提供情况进行了比较。
利用2003年至2013年期间在31个撒哈拉以南非洲国家进行的58次人口与健康调查的数据,以及有关IPTp、ANC和TT的相关问题,来评估ANC就诊情况以及IPTp和TT的提供情况。IPTp提供的一个错过的机会是指一次ANC就诊,根据政策本可以提供IPTp但却没有提供。
在接受调查的国家中,接受≥2剂IPTp的孕妇比例从IPTp政策实施前几乎为零增加到政策实施七年或更长时间后的中位数29.6%(四分位间距20.1 - 42.5%)。ANC就诊率很高(报告≥3次就诊的中位数为76.6%);然而,即使在政策实施七年或更长时间后,中位数为72.9%(四分位间距58.4 - 79.5%)的ANC就诊都是错过提供IPTp的机会。在初产妇中,中位数为61.5%(四分位间距50.9 - 72.9%)接受了两剂TT;除一个接受调查的国家外,推荐的TT接种率超过了IPTp。
即使在政策实施多年后,通过家庭调查衡量的IPTp覆盖率仍低得令人不满意。提供IPTp时众多错过的机会表明,ANC提供服务方面的不足是覆盖率低的一个重要因素。TT的高接种率表明有在ANC提供预防措施的能力。需要进一步研究以确定导致IPTp和TT覆盖率差异的因素,以及如何解决这些问题以提高IPTp覆盖率。
