最近的证据表明，室外空气污染对成年人的认知功能有显着影响。然而，人们对室内空气污染与认知功能障碍的关系知之甚少。因此，当前的研究旨在评估室内空气污染与本地治里农村成年人认知障碍之间的关联。 2018 年 2 月至 3 月期间，对居住在本地治里三级护理机构农村实地实践区的 295 名成年人进行了一项基于社区的横断面研究。使用预先测试的半结构化问卷收集了有关社会人口概况和家庭的信息。进行简易精神状态检查以评估认知功能。我们计算了调整后患病率 (aPR)，以确定与认知障碍相关的因素。在 295 名参与者中，173 名 (58.6) 年龄在 30-59 岁之间； 154 名（52.2%）为女性； 59人（20.0%）曾接触室内空气污染。一般人群中认知障碍的患病率为 11.9%（95% 置信区间 [CI]：8.7–16.1）。暴露于室内空气污染的人群中认知障碍的患病率为 27.1%（95% CI：17.4-39.6）。暴露于室内空气污染的个体（aPR = 2.18，P = 0.003）被发现有两倍的机会出现认知障碍。大约四分之一的参与者暴露在室内空气污染中，其中超过四分之一的人被发现患有认知障碍，是普通人群的两倍。因此，需要通过增加家庭使用的清洁燃料来预防室内空气污染。
Recent evidences showed that outdoor air pollution had significant influence on cognitive functioning of adults. However, little is known regarding the association of indoor air pollution with cognitive dysfunction. Hence, the current study was done to assess the association between indoor air pollution and cognitive impairment among adults in rural Puducherry. A community-based cross-sectional study was done among 295 adults residing in rural field practice area of tertiary care institute in Puducherry during February and March 2018. Information regarding sociodemographic profile and household was collected using pretested semi-structured questionnaire. Mini-Mental State Examination was done to assess cognitive function. We calculated adjusted prevalence ratios (aPR) to identify the factors associated with cognitive impairment. Among 295 participants, 173 (58.6) were in 30–59 years; 154 (52.2%) were female; and 59 (20.0%) were exposed to indoor air pollution. Prevalence of cognitive impairment in the general population was 11.9% (95% confidence interval [CI]: 8.7–16.1). Prevalence of cognitive impairment among those who were exposed to indoor air pollution was 27.1% (95% CI: 17.4–39.6). Individuals exposed to indoor air pollution (aPR = 2.18, P = 0.003) were found to have two times more chance of having cognitive impairment. About one-fourth of the participants were exposed to indoor air pollution, out of which more than one-fourth was found to have cognitive impairment which is twice that of the general population. Hence, prevention of exposure to indoor air pollution needs to be done through increased availability to cleaner fuels for household usage.
