The Relationship Between Physical Activity and Depressive Symptoms in Healthy Older Women.

Depression and inactivity in the elderly are major health problems with significant ramifications for healthy aging. Research shows an inverse relationship between depression and physical activity levels. The purpose of the current investigation is to examine the relationship between physical activity and depressive symptoms in healthy older women, first within the framework of exercise programs, and second via the impact of an intervention. Two experiments were conducted. In the first, 65 women, all above the age of 60, participated. Measures of physical activity were gained by self-report using the International Physical Activity Questionnaire while the measure of depressive symptomatology was the Beck Depression Inventory. In the second, 11 women participated in a line dancing intervention, and their self-reported depressive symptomatology was measured prior to and just after the 6-week exercise intervention using the Beck Depression Inventory. In addition, during the second experiment, pedometer data were gathered during the fourth week. The data of the first study revealed a relationship between the total amount of physical activity and scores on the Beck Depression Inventory; that is, the more active a person is, the lower her self-reported depressive symptoms. Significant correlations were found between the Beck Depression Inventory and the reports of vigorous and moderate exercise levels, but not with walking. Participants who were part of an organized exercise group exercised significantly more than those who exercised on their own. In the second study, those who participated in a line dancing intervention had significantly lower Beck Depression Inventory scores post intervention. The implications of these findings for public health are discussed.
