In a tropical country like Bangladesh, where the climatic condition favors the growth of mosquito vectors, the success of dengue prevention depends largely on the proper identification and control of risk factors. Therefore this study was aimed to explore the potential risk factors and their association with dengue infection.
A case-control study including 150 cases and 150 controls was conducted in Chattogram district of Bangladesh. Cases were confirmed dengue patients admitted in Chattogram medical college hospital and Bangladesh institute of tropical and infectious diseases during August and September 2019. On the other hand, controls were non-dengue patients admitted in other departments of the same hospitals through gender, age, and location matching.
The questionnaire data were collected through telephone-based interviews, which included general demography, daily life activities, housing and surrounding environment of participants. Chi-square and binary logistic regression were performed to identify potential risk factors.
The study found that travel history to the high incidence area, staying most of the daytime in office (AOR = 18.10), living in 21-40 years old houses (AOR = 9.74), and the temporary residency in the city (AOR = 10.20) were statistically significant risk factors for getting dengue infection. However, day time sleep, house type and structure, number of family members, morning and evening walk, plant in resident, and junk yard around 250 m of the house were also showed a significant effect in chi square test.
Results strengthen our understanding regarding the role of factors associated with daily lifestyle and living environment of people in the development of dengue and hence support the dengue control program in Bangladesh. The study will provide a basis for future extended research covering different parts of the country.
在像孟加拉国这样的热带国家，气候条件有利于蚊媒生长，登革热预防的成功很大程度上取决于对风险因素的正确识别和控制。因此，本研究旨在探索潜在风险因素及其与登革热感染的关联。
在孟加拉国吉大港地区开展了一项病例对照研究，包括150例病例和150例对照。病例为2019年8月和9月在吉大港医学院医院和孟加拉国热带与传染病研究所住院的确诊登革热患者。另一方面，对照是通过性别、年龄和地点匹配在同一家医院其他科室住院的非登革热患者。
通过电话访谈收集问卷数据，内容包括一般人口统计学、日常生活活动、参与者的住房和周边环境。采用卡方检验和二元逻辑回归来识别潜在风险因素。
研究发现，前往高发病地区的旅行史、白天大部分时间待在办公室（比值比=18.10）、居住在房龄21至40年的房屋中（比值比=9.74）以及在城市临时居住（比值比=10.20）是感染登革热的统计学显著风险因素。然而，白天睡觉、房屋类型和结构、家庭成员数量、早晚散步、住所内的植物以及房屋周围250米范围内的垃圾场在卡方检验中也显示出显著影响。
研究结果加强了我们对与人们日常生活方式和生活环境相关因素在登革热发病中所起作用的理解，从而支持孟加拉国的登革热防控计划。该研究将为未来覆盖该国不同地区的扩展研究提供基础。
