Objective: The aim of this study was to investigate if individuals who had been brought up by relatives (e.g. parents, siblings and grandparents) who consumed excessive alcohol effected these individuals' own alcohol use in their adult years. The participants in the study were also asked about their alcohol consumption in the past 12 months, and abstainers were asked about their reasons for choosing to live their lives without consuming alcohol. Method: A quantitative approach was used. Data collected from the Icelandic RARHA SEAS were used in this study. A panel of 2500 respondents in the age range of 18-65 years was randomly sampled and was intended to be adequately representative of the Icelandic population. There was a 34.9% response rate ( n=873). Results: Of the 873 source of this study, 26.6% (n=211) categorised as Group A had lived with relatives who excessively consumed alcohol, and this had negatively affected them in their childhood. In their adult years, Group A seemed to be more frequently intoxicated than the control group, Group B (n=659). They also experienced more negative consequences from their alcohol consumption. Group A was likely to consume alcohol to deal with difficult feelings such as depression, and they were also more likely to abstain than Group B. Conclusions: The childhood experience of living with relatives who excessively use alcohol does not impact everyone in the same way in their adult years. Some of them are more likely to use excessive alcohol as adults without relating it to their childhood experience of relatives excessively using alcohol.
