Association of Sources of Worry and Stress with Smoking in Japan: Findings from the Comprehensive Survey of Living Conditions 2010.

Objectives: The purpose of this study is to examine which sources of worry and stress are associated with smoking behavior and if these associations are varied by gender.
Methods: The anonymous data of 28,588 men and 30,813 women aged 20-79 years old in Japan were analyzed. We defined the subjects who chose "smoking everyday" as "smokers." We also assessed 20 sources of worry and stress. Multivariable odds ratios (ORs) and 95% confidence intervals (CIs) of smoking for each source of worry and stress were calculated using logistic regression analysis.
Results: We found significant association of financial stress with smoking behavior in both genders. The multivariable OR (95% CI) of smoking according to stress from financial stress was 1.22 (1.15-1.31) in men and 1.66 (1.53-1.80) in women. Moreover, the OR of smoking according to stress from human relationships and job affairs was significantly higher for women.
Conclusion: We found that some sources of worry and stress were related to smoking behavior and these associations were found to be gender-specific.
