Influence of Interventions on Daily Physical Activity and Sedentary Behavior after Stroke: A Systematic Review.

BACKGROUND: Evidence suggests that frequent engagement in daily activities requiring physical activity may influence risk factors for recurrent stroke. The effects of nonpharmacological interventions on daily physical activity levels and sedentary behavior are unclear. OBJECTIVE: To describe the effects of interventions on levels of daily physical activity and sedentary behavior among people with stroke. METHODS: OVID/Medline, CINAHL, PsycINFO, and the Cochrane Database were searched using the following search terms: stroke, rehabilitation, intervention, sedentary, physical activity, lifestyle, self-management, and exercise. Data extraction and risk of bias assessment were conducted by two authors. RESULTS: Thirty-one interventions were identified that included exercise, behavior change techniques, and education components. These components were delivered alone and in varying combinations. At postintervention, between-group effects on change scores (Cohen's d = 0.17-0.75, P < .05) or between-group differences in odds of participating in daily physical activity (odds ratio [OR] = 2.07, P < .05) were detected in six studies, and within-group effects in nine studies (Cohen's d = 0.21-3.97, P < .05). At follow-up, between-group differences in odds of participating in daily physical activity were detected in one study (OR = 2.64, P < .05), and within-group effects in two studies (Cohen's d = 0.25, P < .05). No effects (P < .05) were detected in 17 studies. CONCLUSION: It may be possible to modify daily physical activity levels and sedentary behavior poststroke; however, there is insufficient evidence to suggest the superiority of a particular intervention approach. Future studies should explore the unique contributions of individual intervention components to guide development of parsimonious multicomponent interventions that are effective for promoting daily physical activity and reducing sedentary behavior among people with stroke. LEVEL OF EVIDENCE: I.

Trajectory of Disability in Older Adults With Newly Diagnosed Diabetes: Role of Elevated Depressive Symptoms.

OBJECTIVE: We examined whether the trajectory of disability differed between older adults with and without elevated depressive symptoms before and after the onset of diabetes mellitus (DM) over 10 years (2004-2014) and explored difficulties in basic and instrumental activities of daily living between the two groups. RESEARCH DESIGN AND METHODS: A generalized linear mixed-model analysis was conducted using five waves (8th-12th) of Health and Retirement Study (HRS) data. We included 419 older adults who self-reported new DM diagnosis within the previous 2 years and used the Center of Epidemiologic Studies Depression Scale to measure elevated depressive symptoms. Disability was measured by 10 items defined in the HRS data set. RESULTS: The trajectory of disability differed between older adults with and without elevated depressive symptoms after newly diagnosed DM over time. Significant and clinically meaningful between-group differences were found in disability after the onset of DM (waves 10 and 11) but not before the onset of DM (waves 8 and 9). Among older adults with elevated depressive symptoms, disability at pre-DM waves (8 and 9) was significantly less than post-DM waves (10-12). Difficulties with shopping, walking, and dressing were mostly reported by older adults with elevated depressive symptoms. CONCLUSIONS: Older adults with newly diagnosed DM and elevated depressive symptoms have a clinically meaningful and faster disablement trajectory than those without elevated depressive symptoms. Future interventions may take an indicated approach to disability prevention in older adults with newly diagnosed DM, especially in those with a change in depression severity.
