“…One population-based study from Taiwan found that higher levels of carbon monoxide exposure were significantly associated with an increased risk of dementia [20]. People in rural Uganda may be exposed to indoor air pollution when they sit around the fire for [21]. Interpretation of our findings is subject to several limitations.…”

Background: There is a paucity of data on the prevalence and correlates of Alzheimer's disease and related dementias in sub-Saharan Africa. The aim of the study was to estimate the prevalence and correlates of Alzheimer's disease and related dementias in rural Uganda. Methods: We conducted a cross-sectional, population-based study in a rural region of southwestern Uganda. The Brief Community Screening Instrument for Dementia was administered to a multi-stage area probability sample of 400 people aged 60 years and over. Multivariable logistic regression was used to estimate correlates of probable dementia. Results: Overall, 80 (20%) of the sample screened positive for dementia. On multivariable regression, we estimated the following correlates of probable dementia: age (adjusted odds ratio [AOR], 1.02 per year; 95% confidence interval [CI], 1.10-1.03, p<0.001), having some formal education (AOR, 0.57; 95% CI, 0.41-0.81, p = 0.001), exercise (AOR, 0.44; 95% CI, 0.27-0.72, p = 0.001), and having a ventilated kitchen (AOR, 0.43; (95% CI, 0.24-0.77, p = 0.001). Conclusions: In this population-based sample of older-age adults in rural Uganda, nearly one-fifth screened positive for dementia.

“…Similar findings were found in a study done in Mexico which reported positive association between exposure to indoor air pollution and cognitive dysfunction. [ 21 ] This implies that people exposed to indoor air pollution are at more risk of having cognitive dysfunction even when compared to other vulnerable population like elderly. Indoor air pollution is already proven to be significant risk factor for respiratory and cardiovascular diseases.…”

Background: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.Methodology: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.Results: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.Conclusion: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.

“…Although previous studies have focused on the role of outdoor air pollution in cognitive decline, only a few studies have examined the association between indoor air pollution and cognition (11,12). Evidence from South India suggested that the risk of cognitive impairment more than doubled in individuals exposed to indoor air pollution (12).…”

“…Evidence from South India suggested that the risk of cognitive impairment more than doubled in individuals exposed to indoor air pollution (12). A study on Mexican adults found that exposure to indoor air pollution was associated with poor cognitive performance, such as poor ability of verbal learning, verbal fluency, and attention (11).…”

Indoor air pollution and cognitive function among older Mexican adults

Abstract: Indoor air pollution may be an important factor for the cognitive health of older Mexican adults. Public health efforts should continue to develop interventions to reduce exposure to indoor air pollution in rural Mexico.
