Relationship between snoring and hypertension in middle-aged and elderly residents in Yangpu District， Shanghai / 上海预防医学

ABSTRACT

ObjectiveTo explore the relationship between snoring and hypertension in middle-aged and elderly residents in Yangpu District， Shanghai. MethodsThe data of this study were obtained from the project of “early screening and comprehensive intervention for high-risk of cardiovascular diseases” carried out by the National Cardiovascular Disease Center in Yangpu District in 2017. Questionnaire survey， physical examination and laboratory test were conducted among permanent residents aged 35‒75 years. Logistic regression model was used to analyze the influence of sleep snoring on hypertension. ResultsA total of 11 100 people with complete data were included in the analysis， The self-reported snoring rate of male was significantly higher than female （48.12% vs 36.21%， χ2=137.70， P<0.01）. The proportion of self-reported occasional snoring， frequent snoring and daily snoring were 14.67%（1 628/11 100）， 7.59%（843/11 100） and 17.50% （1 943/11 100）， respectively， and the prevalence of hypertension gradually increased with the increase of snoring frequency （≤60 years，male： χtrend2=51.83，P<0.01；female： χtrend2=95.01， P<0.01； >60 years， male： χtrend2=9.22， P<0.01； female： χtrend2=27.10， P<0.01）. Multivariate logistic regression analysis showed that in people aged ≤60 years， both men and women， snoring frequency was significantly associated with hypertension after adjusting for education， total family income， smoking， alcohol consumption， diabetes， body mass index （BMI） and waist circumference. In the males： occasional snoring OR （95%CI） was 1.95 （1.36，2.80）， frequent snoring OR （95%CI） was 1.55 （1.04，2.31）， daily snoring OR （95%CI） was 1.92 （1.43，2.59）. In the females： occasional snoring OR （95%CI） was 1.31 （1.08，1.59）， frequent snoring OR （95%CI） was 1.41 （1.07，1.88）， daily snoring OR （95%CI） was 1.63 （1.32，2.00）. But in people aged >60 years， the significant association between snoring frequencies and hypertension did not exist， after adjusting for education， total family income， smoking， alcohol consumption， diabetes， BMI and waist circumference. In the males： occasional snoring OR （95%CI） was 1.31 （0.97，1.78）， frequent snoring OR （95%CI） was 1.22 （0.87，1.73）， daily snoring OR （95%CI） was 1.19 （0.94，1.73）. In the females： occasional snoring OR （95%CI） was 1.06 （0.87，1.29）， frequent snoring OR （95%CI） was 1.30 （0.99，1.72）， daily snoring OR （95%CI） was 1.19 （0.97，1.46）. ConclusionIn people ≤60 years old， snoring is significantly associated with hypertension， so more attention should be paid to sleep snoring monitoring in middle-aged people for early detection of hypertension.
