Association between self-reported snoring and hypertension among Chinese Han population aged 30-79 in Chongqing, China

ABSTRACT

BACKGROUND@#We aim to explore the association between self-reported snoring and hypertension among adults aged 30-79 in Chongqing, China.@*METHODS@#A total of 23,342 individuals aged 30-79 were included at baseline from August 2018 to January 2019, and the final sample size for the analysis was 22,423. Face-to-face interviews and physical examinations were conducted by trained investigators. Logistic regression was performed to study age-specific and gender-specific associations between snoring and hypertension.@*RESULTS@#Frequent snoring was associated with the risk of hypertension for each age and gender group, and the frequency of snoring was positively correlated with the risk for hypertension. For the three age groups (< 45, 45-59, ≥ 60), compared with the non-snoring group, those who snore often had a 64.5%, 53.3%, and 24.5% increased risk of hypertension (< 45 OR = 1.65, 95%CI 1.34-2.02; 45-59 OR = 1.53, 95%CI 1.37-1.72; ≥ 60 OR = 1.25, 95%CI 1.09-1.42), respectively. For men and women, those who snore often had a 46.8% and 97.2% increased risk of hypertension, respectively, than the non-snoring group (men OR = 1.47, 95%CI 1.33-1.63; women OR = 1.97, 95%CI 1.75-2.23).@*CONCLUSIONS@#People who snore frequently should pay close attention to their blood pressure levels in order to achieve early prevention of hypertension, particularly for snorers who are female and aged under 45; importance should be attached to their blood pressure control.
