Hemorrhagic Strokes Attributable to Chronic Alcohol Consumption and Heavy Episodic Drinking in France.

Objectives: To estimate the number of cases and deaths related to hemorrhagic stroke (HS) attributable to a chronic alcohol consumption and to heavy episodic drinking (HED) in France.

Methods: A population-attributable fraction (PAF) estimation approach was used. Relative risks for HS with alcohol consumption were extracted from the INTERSTROKE study. Levels of alcohol consumption in the French population were collected from the 2017 Health Barometer. Data on HS morbidity and mortality were extracted from the French National Health Data System (SNDS).

Results: We estimated that 7.2% (n = 2,100) and 6.6% (n = 1,900) of cases with HS were attributable to chronic alcohol consumption and HED, respectively. PAFs were higher in men than in women with 11.5% vs 2.6% for a chronic consumption and 10.7% vs 2.1% for HED, respectively. We estimated that 7.0% of HS deaths (n = 1,100) were attributable to chronic alcohol consumption and 5.1% attributable to HED (n = 800). Finally, 16.3% of patients with HS (n = 4,700) and 14.1% of HS deaths (n = 2,300) were attributable to overall chronic alcohol consumption or to monthly HED.

Discussion: These results remind the importance of alcohol consumption in the occurrence of HS and the importance of implementing primary and secondary prevention measures, particularly among young people, where HED is most common.
