Factors affecting the increased risk of physical inactivity among older people with depressive symptoms.

The purpose of this study was to investigate the association between depressive symptoms and physical inactivity, and whether motives for and barriers to exercise explain the potential association between depressive symptoms and physical inactivity in older people. The design of the study was cross-sectional. The study population comprised 645 people born between 1922 and 1928 who were residents in a city-center area of Jyväskylä in central Finland. Depressive symptoms were assessed using Center for the Epidemiologic Studies Depression Scale, physical activity using Grimby's (1986) validated scale, and motives for and barriers to exercise using a questionnaire and mobility limitation with a test of walking time over 10 m. The results demonstrated that the risk of physical inactivity was more than twofold among persons with depressive symptoms compared with non-depressed people. A higher prevalence of perceived barriers to physical activity, such as poor health, fear and negative experiences, together with lack of knowledge, explained part of the increased risk of physical inactivity among those with depressive symptoms while differences in motives for physical activity did not have a material effect. Adjustment for walking time over 10 m attenuated the increased risk of inactivity further. When planning exercise promotion programs, finding ways to overcome fear and negative experiences and providing information may help to increase physical activity among people with depressive symptoms. Additionally, difficulties caused by poor mobility should not be ignored.

Customer-oriented counseling for physical activity in older people: study protocol and selected baseline results of a randomized-controlled trial (ISRCTN 07330512).

The objective of this study is to describe the rationale, design and selected baseline results of a 2-year randomized-controlled trial (RCT) on the effects of physical activity counseling in community-living older people. After a four-phase screening and data-collection process targeting all independently living people in the city center of Jyväskylä, Finland, six hundred and thirty-two 75-81-year-old cognitively intact, sedentary persons who were able to move independently outdoors at least minimally and willing to take part in the RCT were randomized into intervention and control groups. At baseline, over half of the subjects exercised less than two to three times a month and two-thirds were willing to increase their physical activity level. The desire to increase physical activity was more common (86%) among subjects with mobility limitation compared with those without (60%, P=0.004). The intervention group received an individualized face-to-face counseling session, followed by phone contacts every 3 months throughout the intervention. The study outcomes include physical activity level, mobility limitation, functional impairments, disability, mood, quality of life, use of services, institutionalization and mortality. The screening and recruitment process was feasible and succeeded well, and showed that unmet physical activity needs are common in older people.
