Note. RR = relative risk; CI = confidence interval.

^aAdjusted for baseline depressive symptomatology.

^bAdjusted for baseline depressive symptomatology, age, gender, marital status, educational level, instrumental activities of daily living status, and number of chronic diseases.

^cSignificance levels refer to differences from reference category.

^dValues refer to the odds of subsequent depressed mood associated with each 1-unit increase in the continuous lifestyle variable.

* P < .05; **P < .01.
