本文采用社会学和流行病学相结合的方法，对高疟山区黎族和苗族上山种植和住宿的行为特征及其与疟疾感染的关系进行了较深入的调查研究，显示苗族村民由于上山住宿率比黎族村民高（其比为８２．１％∶２１．６％），以致原虫检出率更高（其比为２４．１％∶１１．１％），其中恶性疟感染率亦高（其比为９％∶１％）。两民族未上山住宿（ｎ＝２００）、曾上山住宿（ｎ＝２１５）和正在山上住宿（ｎ＝３８）的人群疟原虫率分别为６．５％、２７．４％和４２．１％，恶性疟原虫率分别为０．５％、８．８％和１８．４％，表明因种植而上山住宿是疟疾感染的主要来源，已成为当地疟疾传播的主要方式和控制疟疾的难题。提示今后应加强上山住宿高危人群的疟疾防治措施。
In this paper, a sociological and epidemiological method is used to investigate the behavioral characteristics of the uplifting and accommodation of the Li and Miao peoples in Mount Maoba and their relationship with malaria infection. The results show that the Miao villagers’ Li villagers were taller (their ratio was 82.1%: 21.6%), resulting in a higher detection rate of protozoa (24.1%: 11.1%). The incidence of falciparum malaria infection was also high 9%: 1%). The two ethnic groups did not climb to the mountain (n = 200), and the rates of Plasmodium were 6.5%, 27.4% and 42.1% in those who stayed in the mountains (n = 215) and in the mountains (n = 38) Plasmodium falciparum rates were 0.5%, 8.8% and 18.4%, respectively, indicating that uplifting due to planting is a major source of malaria infection and has become a major source of local malaria transmission and malaria control. It is suggested that malaria prevention and treatment measures should be strengthened in high-risk populations in mountainous areas in the future.
