Association between Exposure to Noise and Air Pollution and Metabolic Syndrome

Abstract Background: In addition to the classical risk factors environmental pollution such as traffic noise and air pollution are suggested to be a risk factor for Metabolic Syndrome (MetS). In this study, we examined the between exposure to noise and air pollution (PM2.5) and MetS.Methods: This study was performed on 3513 participants in a prospective study on the health of the people of Yazd (YaHS). A wide range of demographic, anthropometric and blood biochemistry data were gathered during 2014-2015. Data on personal level noise and air pollution (PM2.5) at residential address were collected through air pollution maps. Air and noise pollution modeling was performed using Kriging model. Using weighted logistic regressiARAon, we reported the odds ratio (95% confidence interval) of MetS for a unit increase in exposure to the pollutants. Results: The prevalence of MetS in the total population was 43.7%. No association was found with MetS between noise exposures in the range (54.1-62.3) dB (A). There was a positive relationship between air pollution exposure in the range (32.82 - 16.38) micrograms per cubic meter and MetS in the raw model and after adjusting for the effect of age and sex, increased air pollution exposure, chance The incidence of MetS increases by 8% (95% CI = 1.06 - 1.10), while the fully adjusted model did not find a positive and significant relationship. Conclusion: We did not find any association between noise and air pollution with MetS in the fully adjusted model.
