Objectives:
The aim of this study was to predict increased alcohol and tobacco use in Fukushima nuclear power plant (NPP) workers 3 years after a nuclear disaster.
Methods:
Surveys were conducted in two postdisaster waves (Wave 1: 2 to 3 months; Wave 2: 32 months). Adjusted risk ratio (aRR) was computed to assess the covariates of increased alcohol and tobacco use in Wave 2.
Results:
Increased alcohol use was associated with age of 29 years or less [aRR (95% confidence interval (95% CI): 1.26 (1.01 to 1.57)], major property loss [1.25 (95% CI 1.02 to 1.55)], and high posttraumatic stress responses (PTSRs) [1.34 (95% CI 1.08 to 1.67)] in Wave 1. Increased tobacco use was associated with age of 29 years or less [1.46 (95% CI 1.12 to 1.90)] and high PTSR [1.62 (95% CI 1.25 to 2.10)] in Wave 1 (P < 0.05).
Conclusion:
The workers' increased alcohol and tobacco use were predicted by major property loss (alcohol), age of 29 years or less, and high PTSR (alcohol/tobacco) in Wave 1.
