背景使用驱虫蚊帐已成为减少疟疾运动的中心重点，非洲许多国家现已开始实施大规模公共卫生方案，旨在向风险最大的人提供驱虫蚊帐。方法我们进行了一项横断面调查，以评估ITN社会营销计划对马拉维城市儿童恶性疟原虫感染和贫血的影响。结果儿童对ITN的知晓率很高，但只有42%的受访儿童报告在前一晚使用过ITN。然而，17%(295/1721)的儿童在登记时恶性疟原虫涂片阳性。使用ITNS可预防52%的疟原虫寄生虫血症。超过三分之二的儿童患有贫血，但使用ITNS的儿童的平均血红蛋白浓度明显高于不使用蚊帐的儿童。ITN的使用与财富有关，因为贫困家庭使用治疗蚊帐的可能性降低了60%。结论尽管ITN社会营销计划具有改善疟疾控制和预防的潜力，但需要做出更多努力才能接触到那些即使是补贴蚊帐也太贵的人。
Background Use of insecticide-treated nets (ITNs) has become a central focus for the Roll Back Malaria campaign, and many countries in Africa have now embarked on large-scale public health programmes aimed at making ITNs available to those at greatest risk. However, the effectiveness of these programmes has rarely been evaluated.Method We conducted a cross-sectional survey to assess the impact of an ITN social marketing programme on Plasmodium falciparum infection and anaemia among children in urban Malawi.Results Knowledge of ITNs was high; however, only 42% of the children surveyed reported to have used an ITN the previous night. Nevertheless, 17% (295/1721) of children had a positive P. falciparum smear at enrolment. Use of ITNs was associated with 52% protective efficacy against Plasmodium parasitemia. More than two-thirds of children were anaemic, yet the mean haemoglobin concentration was significantly higher in children using ITNs than in those not using nets. ITN use was associated with wealth, as poorer households were 60% less likely to use treated nets.Conclusion Although ITN social marketing programmes have the potential of improving malaria control and prevention, additional efforts are required to reach those for whom even subsidized nets are still too expensive.
