Ambient air pollutants aggravate association of snoring with prevalent hypertension: results from the Henan Rural Cohort.

Abstract Aim We aimed to assess if snoring and ambient air pollutants were jointly associated with prevalent hypertension in a cross-sectional study. Methods A total of 28440 participants aged 18–79 years were obtained from the Henan Rural Cohort. Snoring evaluated using Pittsburgh sleep quality index (PSQI) scale was classified into ‘Never’, ‘ Results The mean age of all participants was 56.0 ± 12.2 years. The frequencies and prevalence of participants with hypertension were 3666 (32.39%) in men and 5576(32.57%) in women, respectively. The odds ratio (OR) and 95% confidence interval (CI) of participants with snoring frequency of Conclusions Snoring and high ambient air pollutants might be important predictors of hypertension, and higher concentration of PM1 might aggravate the association between snoring and hypertension.
