Assessment on the ownership and use of mosquito nets in Mozambique

ABSTRACT OBJECTIVE To assess the ownership and use of mosquito nets in 2014, in Mozambique. METHODS This observational and cross-sectional study assessed, in February and March 2015, 69 districts (nine of 11 provinces of Mozambique) that have benefited from the mass distribution of mosquito nets. The Lot Quality Assurance Sampling methodology was used. Each locality was denominated supervision area. The Lot Quality Assurance Sampling opts for a minimum of 19 households (in this case, we decided for a minimum of 100 households per district) from each supervision area to assess an indicator (in this case, two indicators were assessed: ownership and use of mosquito nets). Two questions guided the research: a) received a mosquito net; b) used a mosquito net the night before. RESULTS A total of 6,725 households were assessed. Eighty three percent of them had received mosquito nets in the campaign. Of the 6,232 respondents, 82.0% said they used mosquito nets the night before. The districts of the provinces with low coverage of ownership and use were Tete (69.5% and 60.0%, respectively), Zambezia (79.0% and 60.0%, respectively), and Gaza (81.6% and 70.7%, respectively). The largest coverage of ownership and use were observed in the districts of Nampula (96.7% and 93.8%, respectively) and Niassa (86.0% and 85.4% respectively). CONCLUSIONS In the districts assessed, the progression of ownership and use of mosquito nets is satisfactory. Nampula and Niassa are the only provinces where ownership and use are at desired levels.

摘要 研究目的：评估2014年莫桑比克民众对蚊帐的拥有与使用情况。研究方法：本研究为观察性横断面研究，于2015年2月至3月期间，对莫桑比克11个省份中的9个省份下辖的69个曾开展蚊帐大规模分发的行政区展开评估。本研究采用批量质量保证抽样（Lot Quality Assurance Sampling）方法，将每个调研区域定义为督导片区。批量质量保证抽样法要求每个督导片区至少抽取19户家庭，本研究则将每个行政区的抽样下限设定为100户家庭，以评估两项指标：蚊帐拥有情况与蚊帐使用情况。本次调研围绕两个问题展开：a）是否接收过蚊帐；b）前一晚是否使用过蚊帐。研究结果：本研究共评估6725户家庭。其中83%的家庭曾在蚊帐分发活动中领取到蚊帐。在6232名受访对象中，82.0%的受访者表示前一晚使用过蚊帐。蚊帐拥有与使用覆盖率较低的省份下辖行政区包括太特省（覆盖率分别为69.5%与60.0%）、赞比西亚省（分别为79.0%与60.0%）及加扎省（分别为81.6%与70.7%）。蚊帐拥有与使用覆盖率最高的行政区则来自楠普拉省（分别为96.7%与93.8%）及尼亚萨省（分别为86.0%与85.4%）。研究结论：本次评估的各行政区中，民众对蚊帐的拥有与使用情况整体表现良好。楠普拉省与尼亚萨省是仅有的两项指标均达到预期水平的省份。
