Intermittent preventive treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) is a key malaria prevention strategy in areas with moderate to high transmission. As part of the TIPTOP (Transforming IPT for Optimal Pregnancy) project, baseline information about IPTp coverage was collected in eight districts from four sub-Saharan countries: Democratic Republic of Congo (DRC), Madagascar, Mozambique and Nigeria.
Cross-sectional household surveys were conducted using a multistage cluster sampling design to estimate the coverage of IPTp and antenatal care attendance. Eligible participants were women of reproductive age who had ended a pregnancy in the 12 months preceding the interview and who had resided in the selected household during at least the past 4 months of pregnancy. Coverage was calculated using percentages and 95% confidence intervals.
A total of 3911 women were interviewed from March to October 2018. Coverage of at least three doses of IPTp (IPTp3+) was 22% and 24% in DRC project districts; 23% and 12% in Madagascar districts; 11% and 16% in Nigeria local government areas; and 63% and 34% in Mozambique districts. In DRC, Madagascar and Nigeria, more than two-thirds of women attending at least four antenatal care visits during pregnancy received less than three doses of IPTp.
The IPTp3+ uptake in the survey districts was far from the universal coverage. However, one of the study districts in Mozambique showed a much higher coverage of IPTp3+ than the other areas, which was also higher than the 2018 average national coverage of 41%. The reasons for the high IPTp3+ coverage in this Mozambican district are unclear and require further study.
在疟疾中高传播地区,孕妇采用磺胺多辛-乙胺嘧啶(SP)间歇性预防治疗(IPTp)是预防疟疾的关键策略。作为 TIPTOP(Transforming IPT for Optimal Pregnancy)项目的一部分,在四个撒哈拉以南国家的八个地区收集了关于 IPTp 覆盖率的基线信息:刚果民主共和国(DRC)、马达加斯加、莫桑比克和尼日利亚。
采用多阶段聚类抽样设计进行横断面家庭调查,以估计 IPTp 和产前护理的覆盖率。合格的参与者是在过去 12 个月内结束妊娠的育龄妇女,并且在过去至少 4 个月的妊娠期间居住在选定的家庭中。覆盖率使用百分比和 95%置信区间计算。
2018 年 3 月至 10 月期间共采访了 3911 名妇女。至少接受三次 IPTp 剂量(IPTp3+)的覆盖率在 DRC 项目区为 22%和 24%;在马达加斯加区为 23%和 12%;在尼日利亚地方政府区为 11%和 16%;在莫桑比克区为 63%和 34%。在 DRC、马达加斯加和尼日利亚,超过三分之二的孕妇在怀孕期间至少接受了四次产前护理,而她们接受的 IPTp 剂量不到三次。
调查地区的 IPTp3+接种率远未达到普遍覆盖。然而,莫桑比克的一个研究区的 IPTp3+覆盖率远高于其他地区,也高于 2018 年 41%的全国平均覆盖率。莫桑比克该地区高 IPTp3+覆盖率的原因尚不清楚,需要进一步研究。
