Alcohol consumption and binge drinking in young adult childhood cancer survivors.

BACKGROUND: This study compared frequency of alcohol consumption and binge drinking between young adult childhood cancer survivors and the general population in Switzerland, and assessed its socio-demographic and clinical determinants. PROCEDURE: Childhood cancer survivors aged <16 years when diagnosed 1976-2003, who had survived >5 years and were currently aged 20-40 years received a postal questionnaire. Reported frequency of alcohol use and of binge drinking were compared to the Swiss Health Survey, a representative general population survey. Determinants of frequent alcohol consumption and binge drinking were assessed in a multivariable logistic regression. RESULTS: Of 1,697 eligible survivors, 1,447 could be contacted and 1,049 (73%) responded. Survivors reported more often than controls to consume alcohol frequently (OR = 1.7; 95%CI = 1.3-2.1) and to engage in binge drinking (OR = 2.9; 95%CI = 2.3-3.8). Peak frequency of binge drinking in males occurred at age 24-26 years in survivors, compared to age 18-20 in the general population. Socio-demographic factors (male gender, high educational attainment, French and Italian speaking, and migration background from Northern European countries) were most strongly associated with alcohol consumption patterns among both survivors and controls. CONCLUSIONS: The high frequency of alcohol consumption found in this study is a matter of concern. Our data suggest that survivors should be better informed on the health effects of alcohol consumption during routine follow-up, and that such counseling should be included in clinical guidelines. Future research should study motives of alcohol consumption among survivors to allow development of targeted health interventions for this vulnerable group.
