We conducted a prospective evaluation to measure the physical durability of two brands of long-lasting insecticidal nets (LLINs) distributed during a campaign in 2008 in Nampula Province, Mozambique. Households with LLINs tagged during the campaign (6,000) were geo-located (34%) and a random sample was selected for each of 3 years of follow-up. The LLINs were evaluated in the field and a laboratory for presence of holes and a proportional hole index (pHI) was calculated following the World Health Organization guidelines. We performed 567 interviews (79.0%) and found 75.3% (72.1-78.4%) of households retained at least one LLIN after 3 years; the most common cause of attrition was damage beyond repair (51.0%). Hole damage was evident after 1 year, and increased by year. Olyset had a significantly greater mean number of holes and pHI compared with PermaNet 2.0 brand (all P values ≤ 0.001). Additional information about LLIN durability is recommended to improve malaria control efforts.
我们进行了一项前瞻性评估，以测定2008年在莫桑比克楠普拉省开展的一次活动中分发的两个品牌长效驱虫蚊帐（LLINs）的物理耐用性。在活动期间标记有LLINs的家庭（6000户）进行了地理位置定位（34%），并为3年随访中的每一年选取了一个随机样本。在实地和实验室对LLINs进行了孔洞检查，并按照世界卫生组织的指南计算了比例孔洞指数（pHI）。我们进行了567次访谈（79.0%），发现75.3%（72.1 - 78.4%）的家庭在3年后至少保留了一顶LLINs；损耗的最常见原因是损坏无法修复（51.0%）。1年后孔洞损坏就很明显，并逐年增加。与PermaNet 2.0品牌相比，Olyset的平均孔洞数量和pHI显著更高（所有P值≤0.001）。建议提供有关LLINs耐用性的更多信息，以改善疟疾防控工作。
