“…In addition, exposure to air pollution, both indoor and outdoor, is a potential contributing factor to the TB epidemic (Lin et al 2007;Popovic et al 2019). Some studies have revealed associations between TB cases and indoor air pollution, primarily due to the inhalation of environmental pollutants such as tobacco smoke and biomass fuel smoke (Jafta et al 2019;Patel et al 2020). In recent years, the association between ambient air pollution and TB risk has received constant attention from scholars (Ge et al 2017;Lai et al 2016;Li et al 2019;Smith et al 2016;Sohn et al 2019;Zhu et al 2018).…”

To analyze the association of long-term exposure to air pollution and its attributable risks with the number of tuberculosis (TB) cases notified, a quasi-Poisson regression model combined with a distributed lag nonlinear model (DLNM) was constructed using monthly data on air pollution and TB cases notified in Hong Kong from 1999 to 2018. Nonlinear relationships between PM10, PM2.5, and CO and TB cases notified were identified. The concentrations of PM10, PM2.5, and CO corresponding to the minimum numbers of TB cases notified (the minimum TB notification concentrations, MTNCs) were 58.3 μg/m 3 , 41.7 μg/m 3 , and 0.1 mg/m 3 , respectively. Compared with the MTNCs, the overall cumulative numbers of TB cases notified increased by 76.93% (95% CI: 13.08%, 176.83%), 88.81% (95% CI: 26.09%, 182.71%), and 233.43% (95% CI: 13.56%, 879.03%) for the 95th percentiles of PM10 and PM2.5 and for the 97.5th percentiles of CO, respectively. The TB notification rate attributed to concentration ranges above the 97.5th percentile of PM10, PM2.5, and CO were 3.38% (95% empirical confidence intervals [eCI]: 0.93%, 5.61%), 4.73% (95% eCI: 1.87%, 7.15%), and 3.34% (95% eCI: 0.29%, 5.83%), respectively. Long-term exposure to high concentrations of air pollution in Hong Kong may be associated with increases in the number of TB cases notified for this area.

“…The combustion of solid fuels emits many chemicals which impact human health, including PM, carbon dioxide, carbon monoxide, sulfur dioxide (SO 2 ), sulfur trioxide, nitrogen dioxide, and nitric oxide [ 29 ]. There is increasing evidence that PM exposure weakens anti-mycobacterial host immunity [ 30 , 31 ]. Chronic PM exposure accompanied by high constitutive expression of pro-inflammatory cytokines results in relative cellular unresponsiveness [ 31 , 32 ].…”

Background Tuberculosis (TB) and indoor air pollution (IAP) are equally critical public health issues in the developing world. Mongolia is experiencing the double burden of TB and IAP due to solid fuel combustion. However, no study has assessed the relationship between household solid fuel use and TB in Mongolia. The present study aimed to assess the association between household solid fuel use and TB based on data from the Mongolian National Tuberculosis Prevalence Survey (MNTP Survey). Method The MNTP Survey was a nationally representative population-based cross-sectional survey targeting households in Mongolia from 2014 to 2015, with the aim of evaluating the prevalence of TB. The survey adopted a multistage cluster sampling design in accordance with the World Health Organization prevalence survey guidelines. Clusters with at least 500 residents were selected by random sampling. A sample size of 98 clusters with 54,100 participants was estimated to be required for the survey, and 41,450 participants were included in the final analysis of the present study. A structured questionnaire was used to collect information on environmental and individual factors related to TB. Physical examination, chest X-ray, and sputum examinations were also performed to diagnose TB. Results The use of solid fuels for heating (adjusted odds ratio (aOR): 1.5; 95% confidence interval (CI): 1.1–2.1), male gender (aOR: 2.2; 95% CI: 1.6–3.2), divorced or widowed (aOR: 2.6; 95% CI: 1.7–3.8), daily smoker (aOR: 1.8; 95% CI: 1.3–2.5), contact with an active TB case (aOR: 1.7; 95% CI: 1.2–2.3), being underweight (aOR: 3.7; 95% CI: 2.4–5.7), and previous history of TB (aOR: 4.3; 95% CI: 3.0–6.1) were significantly associated with bacteriologically confirmed TB after adjusting for confounding variables. Conclusion The use of solid fuels for heating was significantly associated with active TB in Mongolian adults. Increased public awareness is needed on the use of household solid fuels, a source of IAP.

“… 22 Indoor air pollution has shown to be an important predisposing and enabling factor for tuberculosis. 23 , 24 Usage of unclean cooking fuel which is rampant in developing countries is one of the important causes globally for indoor air pollution. 25 , 26 This study also supports this finding.…”

Background: Tuberculosis affects around 30% of the population of the world. Tuberculosis causes an increase in early mortality and thus has the potential to increase the number of years of life lost. Globalization directly or indirectly by affecting the factors that increase the susceptibility for tuberculosis infection has the potential to increase the spread and mortality due to tuberculosis. This study assessed the causal link between globalization and the years of life lost due to tuberculosis. Methods: Data from the Demographic and Health Survey (DHS) and World Bank for 2004 and 2005 were used for a number of covariates and possible mediators. Data from the Institute of Health Metrics and Evaluation (IHME) were used for the outcome variable and important globalization indicators. The primary health outcome that was studied is tuberculosis and the measure that was used to quantify tuberculosis mortality is the years of life lost (YLL). Path analysis was used. Results: The main independent variables of economic and social integration were not statistically significant. For every unit increase in the proportion of people that were using treated drinking water, there was a -0.0002 decrease in the YLL due to tuberculosis. For every unit increase in the proportion of people with earth floor, there was a 0.0002 units increase in YLL due to tuberculosis. For every unit increase in the proportion of people living using clean fuel, there was a 0.0004 decrease in the YLL due to tuberculosis. Conclusions: Social and economic globalization have no effect on the years of life lost due to tuberculosis, highlighting that globalization actually does not contribute to tuberculosis mortality. However, improving other important determinants such as sanitation, providing safe drinking water and clean households will reduce the mortality due to tuberculosis, highlighting the need to invest in them.
