Title:Possible role of air pollution in development and severity of type-2 diabetes
Using Geographic Information System software and 2005 California Health Interview Survey (CHIS) data, adults' residential addresses were linked to government monitors for NO2, O3, PM10 and PM2.5. Individual 3-year average exposures were estimated. Logistic regression analyses evaluated associations between pollutant exposures and increased odds of type-2 diabetes diagnosis, as well as increased odds of taking medication (specifically pills, insulin, or both) to treat type-2 diabetes, controlling for age, sex, race, and poverty level.
Among CHIS 2005 respondents, 3% and 8% increased odds of type-2 diabetes diagnosis were suggested with increases in PM10 and NO2, respectively. Among adults with type-2 diabetes, increased O3, PM10, and PM2.5 were associated with increased odds of taking any medication (40%, 56%, and 50%, respectively), and specifically pills only (33%, 31%, and 41%, respectively), insulin only (43%, 53%, and 46%, respectively), and insulin and pills (70%, 60%, and 88%, respectively).
Criteria pollutant exposures are potentially related to type-2 diabetes prevalence and severity. Modest effects of air pollution on diabetes risk will have widespread impact due to high incidence and ubiquity of exposure. Understanding this relationship provides novel information regarding modifiable environmental risk factors contributing to this growing epidemic.
