[Alcohol consumption and treatment of hypertension. Results of an occupational medicine survey].

The results of a cross-sectional study were analysed in order to assess the therapeutic control of hypertension in relation to alcohol consumption. 6,665 subjects, employed in small and medium-sized companies of the Paris region were examined in a cross sectionnal study. Among the 1,008 hypertensive subjects, awareness of hypertension decreased with increasing alcohol consumption, from 72% among the 304 non-drinkers to 59% among the 201 heavy drinkers (six glasses/day and more) (p less than 0.05). Similarly, the percentage of subjects under current antihypertensive medication on the day of examination was lower in heavy drinkers, 19%, than among tetotalers, 42% (p less than 0.001). An antihypertensive treatment had been prescribed to 510 subjects. Among them, compliance, as stated by the interview, decreased with increasing alcohol consumption, from 70% to 34% (p less than 0.001). Using a logistic regression, the adjusted relative risk of non-compliance among heavy drinkers (6 glasses/day or more) was found to be 1.9. Among the 344 subjects under antihypertensive treatment on the day of examination, systolic and diastolic blood pressure were higher among heavy drinkers, 167/102 mmHg, than among teetotallers, 154/95 mmHg (p less than 0.01 both). The relative hypertension awareness, treatment and control status was thus poorer among, moderate and heavy drinkers than among the light and non-drinkers (table I). (Table: see text). The importance of the problem of alcoholism is thus emphasized, in both the fields of hypertension prevalence and control.
