Malaria in pregnancy is a major public health concern, contributing to roughly 11% of neonatal deaths and to 25% of all maternal deaths in some parts of the world. The World Health Organization has recommended priority interventions for malaria during pregnancy, including use of insecticide-treated nets (ITNs), but net distribution has shifted recently to a universal coverage paradigm rather than one targeting vulnerable populations.
To determine whether and to what extent pregnant women are prioritized within the household for ITN use, we assessed national survey data from 2009-2013 in 10 African countries. Proportion of pregnant women who slept under an ITN the previous night and 95% confidence intervals were calculated and compared between countries. Within-country logistic regression examined whether pregnancy was significantly associated with ITN use the previous night compared with other risk groups, and the predicted probability of net use for each risk group was calculated holding other covariates constant.
A median 58% of households reported owning at least 1 ITN. On average, across all 10 countries, 35% of pregnant women in households with at least 1 ITN used a net. Households with universal coverage (at least 1 ITN per 2 people) had higher levels of net use among all family members; for example, 79% of pregnant women, on average, used a net in such households. In all countries, the predicted probability of ITN use by pregnant women was significantly higher than the probability of net use by most other household members except non-pregnant women of reproductive age.
These findings suggest that both pregnant women and non-pregnant women of reproductive age are being prioritized within the household for net use. However, behavior change communication strategies are needed to achieve ITN use goals for pregnant women.
妊娠疟疾是一个重大的公共卫生问题,在世界某些地区,约11%的新生儿死亡及25%的孕产妇死亡与之有关。世界卫生组织已推荐了孕期疟疾的优先干预措施,包括使用经杀虫剂处理的蚊帐(ITN),但蚊帐分发最近已转向普遍覆盖模式,而非针对弱势群体的模式。
为确定孕妇在家庭中使用ITN是否被优先考虑及优先程度,我们评估了2009年至2013年10个非洲国家的全国调查数据。计算前一晚睡在ITN下的孕妇比例及95%置信区间,并在各国之间进行比较。国内逻辑回归分析了与其他风险组相比,前一晚怀孕是否与使用ITN显著相关,并在保持其他协变量不变的情况下,计算每个风险组使用蚊帐的预测概率。
家庭报告拥有至少1顶ITN的中位数为58%。在所有10个国家中,平均而言,拥有至少1顶ITN的家庭中35%的孕妇使用了蚊帐。实行普遍覆盖(每两人至少1顶ITN)的家庭中所有家庭成员的蚊帐使用率更高;例如,此类家庭中平均79%的孕妇使用了蚊帐。在所有国家,孕妇使用ITN的预测概率显著高于除育龄非孕妇外的大多数其他家庭成员使用蚊帐的概率。
这些发现表明,孕妇和育龄非孕妇在家庭中使用蚊帐方面都被优先考虑。然而,需要行为改变沟通策略来实现孕妇使用ITN的目标。
