众所周知，在农舍过夜有感染疟疾的危险。然而，报告风险的研究是在蚊帐覆盖率低的情况下进行的。这项研究旨在评估如果正确使用驱虫蚊帐，在农舍过夜是否与疟疾感染风险增加有关。2008年3月（旱季）和8月（雨季）在老挝色贡省的Lamarm区进行了一对横断面调查。在3月（127户，891人）和8月（128户，919人），对随机选择的三个村庄的农民及其家庭成员进行了基于问卷的访谈和血液检查。Logistic回归分析，调整潜在的混杂因素，用于评估疟疾感染状况和两个季节研究前两周过夜停留频率之间的相关性。3月份，13.7%的参与者报告说，在过去两周内至少有一次在农场小屋过夜。8月份，这一比例上升至74.6%。不仅成年人，而且年幼的孩子也像成年人一样经常过夜。前一天晚上使用驱虫蚊帐的情况在农房（3月为66.3%，8月为95.2%）和主要住宅（3月为85.8%，8月为92.5%）都很常见。Logistic回归分析显示，在两个研究期间，疟疾感染状况和在农舍过夜的频率之间没有统计学关联。然而，在旱季，与五人或五人以上共用一个家庭式蚊帐的人比与两人共用一个蚊帐的人患疟疾的可能性要大得多。这项研究表明，在农房中广泛使用驱虫蚊帐的环境中，在农房中过夜与疟疾感染风险增加无关。这表明，如果在老挝农村正确使用驱虫蚊帐，在农舍过夜期间感染疟疾可能是可以预防的。
Overnight stays in farming huts are known to pose a risk of malaria infection. However, studies reporting the risk were conducted in the settings of poor net coverage. This study sought to assess whether an overnight stay in a farming hut is associated with an increased risk of malaria infection if insecticide-treated bed nets (ITNs) are properly used. A pair of cross-sectional surveys was carried out in the Lamarm district of Sekong province, Laos, in March (dry season) and August (rainy season) in 2008. Questionnaire-based interviews and blood examinations were conducted with farmers and their household members from three randomly selected villages in March (127 households, 891 people) and August (128 households, 919 people). Logistic regression analysis, adjusted for potential confounding factors, was used to assess the association between malaria infection status and frequency of overnight stays for the two weeks prior to the study in both the seasons. In March, 13.7% of participants reported staying overnight in a farming hut at least once in the previous two weeks. The percentage increased to 74.6% in August. Not only adults but also young children stayed overnight as often as adults. The use of an ITN the preceding night was common both in farming huts (66.3% in March, 95.2% in August), and in main residences (85.8% in March, 92.5% in August). Logistic regression analysis showed no statistical association between malaria infection status and frequency of overnight stays in farming huts in either study period. However, people sharing one family type net with five people or more were significantly more likely to have malaria than those sharing a net with up to two people in the dry season. This study showed that staying overnight in farming huts was not associated with an increased risk of malaria infection in the setting where ITNs were widely used in farming huts. It suggests that malaria infection during overnight stays in farming huts might be preventable if ITNs are properly used in rural Laos.
