SNORING AND CARDIOVASCULAR RISK-FACTORS

The association of snoring with some cardiovascular risk factors was s tudied cross-sectionally by a postal survey among 3750 males aged 40-5 9 years. In univariate analyses, snoring associated statistically sign ificantly (P<0.01) with hypertension, smoking, obesity, heavy alcohol use, physical inactivity, dyspnoea, hostility and morning tiredness. I n a multiple logistic regression model adjusted by age, snoring associ ated significantly with smoking, obesity, physical inactivity, hostili ty and morning tiredness. When smoking was excluded from the multivari ate model, alcohol use was also associated significantly with snoring. The association of snoring with smoking, and with obesity seemed to b e almost independent from other studied correlates of snoring. Our res ults indicate that in further studies on predictive value of snoring w ith regard to coronary heart disease and stroke, the associations of s noring with hypertension, smoking, obesity, heavy alcohol use, physica l inactivity and hostility have to be considered, as these risk charac teristics may cause confounding effects.
