We examined the risks associated with health status and lifestyle factors in the baseline survey using a logistic regression model. Results An age-adjusted analysis showed an increased risk of depression in those who had poor perceived health and chronic diseases in both sexes. In men those who were physically inactive also had an increased risk of depression. In women the analysis also showed an increased risk of depression those with a BMI of 25 or more in those sleeping 9 hours a day or more and who were current smokers.
