We examined risk factors associated with Necator americanus infection among persons aged > or =50 years in Hainan Province, People's Republic of China. Age and sex made the most important contributions to the variation in infection intensity (28%-30%), with age alone responsible for 27% of this variation. When stratified by 20-year age intervals, the influence of shared residence was 23% for persons aged > or =50 years and 27% for those aged <20 years, who had the highest and lowest levels of infection intensity, respectively. This points to shared residence as a means of capturing the complex relationship between aging and shared socioeconomic, environmental, and behavioral factors that influence transmission of Necator infection. None of the other 26 personal or 32 household risk factors were found to be significant. The importance of aging in Necator infection reveals an emerging public health problem among the elderly population of developing countries.
我们对中华人民共和国海南省50岁及以上人群中美洲板口线虫感染的相关危险因素进行了研究。年龄和性别对感染强度的变化贡献最大（28%-30%），仅年龄一项就占该变化的27%。按20岁年龄间隔分层时，对于50岁及以上人群，同住的影响为23%，而对于年龄小于20岁的人群，同住的影响为27%，这两组人群的感染强度分别处于最高和最低水平。这表明同住是一种体现衰老与影响美洲板口线虫感染传播的社会经济、环境及行为等综合因素之间复杂关系的方式。未发现其他26项个人危险因素或32项家庭危险因素具有显著性。衰老在美洲板口线虫感染中的重要性揭示了发展中国家老年人群中一个新出现的公共卫生问题。
