Marital Status, Smoking and Binge Drinking in Comparative Perspective. The paper explores cross-national differences in the link between marital status, smoking and binge drinking. Using the International Social Survey Data (ISSP Health and Health Care) from 2011, it tests whether the gap between married and single individuals depends on the prevalence of the vice in the society. This hypothesis was partly corroborated for binge drinking in both male and female samples though the link between marriage and alcohol consumption is reversed in the high prevalence context. In case of smoking, the idea of the decreasing role of marriage in countries where tobacco use is widespread was confirmed only among men. The analysis also showed that cohabitation was not as strongly linked to health practices as marriage.
