- Abstract
Background Associations of higher levels of physical activity with fewer depressive symptoms have been reported from both cross-sectional and longitudinal studies. However, there are few data in elderly populations. We studied the association between physical activity and 8-year incident depressive symptoms in a cohort of elderly Japanese-American men. Methods The Honolulu-Asia Aging Study is a continuation of the Honolulu Heart Program, a longitudinal population-based study of Japanese- American men on Oahu, Hawai'i. At the fourth exam in 1991-93, 3734 survivors aged 71-93 years were examined. Physical activity was assessed by self-reported distance walked per day. Depressive symptoms were measured with an 11-question version of the Centers for Epidemiologic Studies Depression Scale (CES-D) at the 4th exam (n = 3196) and again at the 7th exam 8 years later (1999-2000, n = 1417). Presence of depressive symptoms was defined as CESD- 11 score ≥ 9 or taking anti-depressants. Subjects with prevalent depressive symptoms at exam 4 were excluded from the incidence analysis. Chi square, t-tests and multiple logistic regression models were used for analyses. This study was approved by the IRB of Kuakini Medical Center. Results Incident depressive symptoms were present in 9.8% of men. Age adjusted 8-year incident depressive symptoms were 13.6%, 7.6% and 8.5% for low (< 1/4 miles/day), intermediate (1/4 to 1.5 miles/ d) and high (>1.5 miles/day) walking groups at baseline, p=0.008. Multiple logistic regression analyses were adjusted for age, education, marital status, BMI, hypertension, diabetes, alcohol, smoking status, prevalent coronary heart disease, stroke, cancer, Parkinson's disease, dementia or cognitive impairment and difficulty walking. Compared to the lowest walking group (reference), those in the intermediate and highest walking groups had significantly lower odds for developing 8-year incident depressive symptoms (OR = 0.52; 95% CI = 0.32-0.83, p = 0.006; and OR = 0.61; 95% CI = 0.39-0.97, p = 0.04 respectively). Conclusion Daily physical activity, even low level activity such as walking, is strongly associated with a lower risk for development of depressive symptoms over eight years in elderly Japanese-American men.
