“…Outdoor air pollution originated in traffic and industrial emissions may affect host susceptibility in the lung to infection by altering immunologic processes such as function of pulmonary macrophages, polymorphonuclear leukocytes, and epithelial cells 8 . However, two epidemiologic studies conducted in South Korea failed to find association between ambient air pollutant concentrations and TB incidence, with the exception of sulfur dioxide (SO₂) 9,10 . While the biological mechanisms described above suggests that there may be time lag between PM exposure and TB incidence, the two studies did not scrutinize the time lag.…”

OBJECTIVES: Epidemiological evidence of associations between ambient particulate matter (PM) and tuberculosis (TB) risk is accumulating. Two previous studies in Korea found associations between air pollution—especially sulfur dioxide (SO2)—and TB. In this study, we conducted an annual time-series cross-sectional study to assess the effect of PM with an aerodynamic diameter less than 10 μm (PM10) on TB risk in seven major cities of Korea from 2010 to 2016, taking into account time lag and long-term cumulative exposure.METHODS: Age-standardized TB notification rates were derived using the Korea National TB Surveillance System. Annual average PM10 concentrations were obtained from annual Korean air quality reports. We applied a generalized linear mixed model with unconstrained distributed lags of exposure to PM10. We adjusted for potential confounders such as age, health behaviors, and area-level characteristics.RESULTS: Both average annual PM10 concentrations and age-standardized TB notification rates decreased over time. The association between cumulative exposure to PM10 and TB incidence became stronger as a longer exposure duration was considered. An increase of one standard deviation (5.63 μg/m3) in PM10 exposure for six years was associated with a 1.20 (95% confidence interval, 1.17 to 1.22) times higher TB notification rate. The marginal association of exposure duration with the TB notification rate was highest at four and five years prior to TB notification. This association remained consistent even after adjusting it for exposure to SO2.CONCLUSIONS: The findings of this study suggest that cumulative exposure to PM10 may affect TB risk, with a potential lag effect.

Gauza jakina da gizarte-faktore desberdinek zenbait gaixotasunen intzidentzia eta eboluzioa baldintzatzen dutela, mundu-mailan zein EAEn. Lan honen helburu nagusia Gipuzkoan 2010-2017 denboraldian maila sozioekonomikoaren eta betidanik pobreziarekin erlazionatutako gaitz baten arteko lotura aztertzea izan da; alegia, gabezia-mailaren eta tuberkulosiaren arteko harremana ikertzea. Bigarren helburua 2003-2017 urteetan zehar gaixotasun horren eboluzioa deskribatzea izan da. Maila sozioekonomikoa analizatzeko, paziente bakoitzari modu ekologikoan esleitutako gabezia-indizea erabili da, diagnostiko aldian bizi ziren errolda-sekzioko informazioaz baliatuta. Intzidentzien kalkulurako, 2011ko erroldatik lortu da biztanle kopurua, sekzio bakoitzeko eta adinaren zein sexuaren arabera, eta urte bereko EAEko populazioa erabilita estandarizazioa egin da. Biriketako lokalizazioa zuten kasuetan, maila sozioekonomikoa diagnostikoaren atzerapenarekin eta tratamendua betetzearekin elkarturik ote dagoen ere ikertu da. Horretarako hainbat analisi estatistiko erabili dira, SPSS programaz baliatuz. Lortutako emaitzei so eginez, Gipuzkoan tuberkulosiaren intzidentzia ekologikoki esleitutako gabezia-mailarekin elkarturik dagoela ondoriozta daiteke. Izan ere, maila sozioekonomiko baxuenean kokatzen diren pertsonek maila altuenean daudenek baino tuberkulosia izateko arrisku handiagoa dutela ikusi da; arriskuaren igoera estatistikoki esangarria izanik gizonetan (tasa estandarizatuaren arrazoia: 2,15, konfiantza-tartea: 1,51-3,07). Hala ere, azken 15 urteetan maila sozioekonomikoen arteko desberdintasunak murriztu direla ikus daiteke. Osasun-arretari dagokionez, ez da maila sozioekonomikoaren eta diagnostikoaren atzerapenaren arteko erlaziorik aurkitu; bai, ordea, tratamendua betetzearekin, gabezia-maila baxuetan tratamendua betetzeko probabilitatea txikiagoa izanik.

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.
