Background It has been reported that alcohol consumption increases after natural disasters, with an impact on health. However, the impact of relocation upon drinking behavior has been unclear. The aim of this study was to clarify the association between housing type and the impact of alcohol consumption on health after the Great East Japan Earthquake (GEJE) of 2011. Methods We analyzed 569 residents living in devastated areas of Ishinomaki city, who had undergone assessment of their γ-GTP levels at health check-ups in both 2010 and 2013, and had given details of the type of housing they occupied in 2013. The housing types were categorized into five groups: “same housing as that before the GEJE”, “prefabricated temporary housing”, “privately rented temporary housing/rental housing”, “homes of relatives”, and “reconstructed housing”. We used fixed-effect regression analysis to examine the association between housing type after the GEJE and changes in γ-GTP after adjustment for age, BMI, housing damage, number of people in household, smoking status, presence of illness, psychological distress, and social network. Results The mean age of the participants was 71.5 years and 46.2% of them were men. The proportion of individuals who drank heavily, and suffered from psychological distress and insomnia, was highest among those living in privately rented temporary housing/rental housing. Compared with individuals who continued to occupy the same housing as those before the GEJE, the effect of change in γ-GTP was significantly higher in individuals who had moved to privately rented temporary housing/rental housing (b = 9.5, SE = 4.4, p < 0.05). Conclusion Our present findings reveal that disaster victims who have moved to privately rented temporary housing/rental housing are at highest risk of negative health effects due to alcohol drinking.
