We analyzed datasets of the Taiwan Longitudinal Survey on Aging, and used self-reported stress in 2003 and 2007 to represent long-term stress conditions in 4854 ¡Ý 50-year old persons. The impact of long-term stress on depressive status (evaluated with CES-D10, score range 0-30) was determined with multivariate logistic regression analysis. Persons with proxy interviews, incomplete CES-D data, or cognitive impairment were excluded.
Perceived-health stress had stronger impacts on depressive symptoms than most other stress situations. Job-related stress showed no impact. Other stress situations showed modest associations in the middle-aged and young-olds. Ongoing stress had stronger impacts than past stress. Excluding health and job stresses, the impact generally decreased with aging. The association with clinically relevant depression generally followed that with depressive symptoms.
All perceived stresses are not equal in their impacts on subsequent depressive symptoms. Perceived-health stress has stronger impacts under most conditions. Better understanding of the associations of various stressors with depressive symptoms could enhance planning of effective strategies to reduce the risk of depression in older persons.
