Modification of the association of alcohol drinking with blood pressure by cigarette smoking.
The purpose of this study was to investigate whether the association of alcohol drinking with blood pressure was modified by cigarette smoking. The subjects were healthy male workers aged 40-59 years and were divided into three different groups by average daily consumption of alcohol (non-drinkers; light drinkers, less than 30 g ethanol per day; heavy drinkers, 30 g or more ethanol per day) and cigarettes (non-smokers; light smokers, less than 20 cigarettes per day; heavy smokers, 20 cigarettes or more per day). The mean levels of both systolic and diastolic blood pressures were significantly lower in the light and heavy smoker groups than in the non-smoker group. In the light and heavy smoker groups, systolic blood pressure was higher in the light drinker subgroup than in the non-drinker subgroup, while there was no significant difference between systolic blood pressures in the non- and light drinker subgroups of non-smokers. In the non-, light and heavy smoker groups, systolic and diastolic blood pressures were significantly higher in the heavy drinker subgroup than in the non-drinker subgroup, and these differences tended to be greater in light and heavy smokers than in non-smokers. The above differences in the relationships of alcohol drinking with blood pressure in non-, light and heavy smokers were also observed when age and body mass index were adjusted and when alcohol intake-matched groups were used. These results suggest that the association of alcohol drinking with blood pressure is stronger in smokers than in non-smokers, independently of age, body mass index and alcohol intake.
