Abstract
The association of snoring with some cardiovascular risk factors was studied cross-sectionally by a postal survey among 3750 males aged 40–59 years. In univariate analyses, snoring associated statistically significantly (P<0.01) with hypertension, smoking, obesity, heavy alcohol use, physical inactivity, dyspnoea, hostility and morning tiredness. In a multiple logistic regression model adjusted by age, snoring associated significantly with smoking, obesity, physical inactivity, hostility and morning tiredness. When smoking was excluded from the multivariate model, alcohol use was also associated significantly with snoring. The association of snoring with smoking, and with obesity seemed to be almost independent from other studied correlates of snoring. Our results indicate that in further studies on predictive value of snoring with regard to coronary heart disease and stroke, the associations of snoring with hypertension, smoking, obesity, heavy alcohol use, physical inactivity and hostility have to be considered, as these risk characteristics may cause confounding effects.
