疟疾发病率和死亡率的模式可能因某一地区疟疾传播程度的不同而有所不同。我们进行了两次年度横断面调查，在低流行性疟疾社区的莫龙，菲律宾，研究感染的流行病学和社会行为的危险因素。在这两项调查中，患疟疾的最大风险与居住地有关。例如，在第一次调查中，生活在超过50%的社区IFAT滴度高的地区，调整后的比值比（OR）为33.7。一系列被认为与风险相关的活动进行了检查，但在第一次调查中，只有频繁的夜间访问森林被认为是一个重要的风险因素（调整后的OR，2.65; 95%CI 1.48，4.73），但这种现象主要是在居住在最低流行地区的个人中观察到的。在第二次调查中，只对疟疾流行率相对较高的地区进行了抽样，未发现与活动有关的情况，在这次调查中，与疟疾感染有关的重要因素有：（调整OR 1.97; 95% CI 1.33，2.92），男性（调整OR 1.63; 95% CI 1.10，2.43）和年龄30岁或以下（年龄> 30岁调整OR 0.29; 95% CI 0.16，0.52）。数据表明，在低流行社区，如莫隆，巴丹，控制工作应主要针对血清学确定的重点地区，特别是在移民和男性年轻人。(C)1997 Elsevier Science B.

The patterns of malaria morbidity and mortality can vary with the level of malaria transmission in a given area. We carried out two annual cross-sectional surveys in the hypoendemic malarious community of Morong, the Philippines, to examine epidemiologic and sociobehavioural risk factors for infection. In both surveys, the greatest risk of having malaria was associated with place of residence. For example, in the first survey, living in an area where more than 50% of the community had a high IFAT titer had an adjusted odds ratio (OR) of 33.7. A range of activities thought to be associated with risk were examined, but in the first survey, only frequent nocturnal visits to the forest were found to be a significant risk factor overall (adjusted OR, 2.65; 95% CI 1.48, 4.73), but this phenomenon was primarily observed among individuals residing in the lowest prevalence areas. In the second survey, where only the area with a relatively high prevalence of malaria was sampled, no association with activities was found. In this survey, significant factors associated with malarial infection were: being a migrant (adjusted OR 1.97; 95% CI 1.33, 2.92), being male (adjusted OR 1.63; 95% CI 1.10, 2.43) and age 30 years or less (adjusted OR 0.29 for age > 30 years; 95% CI 0.16, 0.52). The data suggest that in low-endemic communities like Morong, Bataan, control efforts should be primarily directed to focal areas identified by serology, particularly among migrants and among male young adults.
