A minority of published evidence -based PA interventions for adults with T2D were both effective and pragmatic for clinical implementation .
Although regular physical activity ( PA ) is a cornerstone of treatment for type 2 diabetes ( T2D ) , most adults with T2D are sedentary .
R and omized controlled trials ( RCTs ) have proven the effectiveness of PA behavioral interventions for adults with T2D but have rarely been conducted in healthcare setting s. We sought to identify PA interventions that are effective and practical to implement in clinical practice setting s. Our first aim was to use the valid Pragmatic-Explanatory Continuum Indicator Summary 2 ( PRECIS-2 ) tool to assess the potential for future implementation of PA interventions in clinical practice setting s. Our second aim was to identify interventions that effectively increased PA and glycemic control among the interventions in the top tertile of PRECIS-2 scores .
Mediators of physical activity change in a behavioral modification program for type 2 diabetes patients
Background Many studies have reported significant behavioral impact of physical activity interventions . However , few have examined changes in potential mediators of change preceding behavioral changes , result ing in a lack of information concerning how the intervention worked . Our purpose was to examine mediation effects of changes in psychosocial variables on changes in physical activity in type 2 diabetes patients . Methods Ninety-two patients ( 62 ± 9 years , 30 , 0 ± 2.5 kg/m2 , 69 % males ) participated in a r and omized controlled trial . The 24-week intervention was based on social-cognitive constructs and consisted of a face-to-face session , telephone follow-ups , and the use of a pedometer .  Social-cognitive variables and physical activity  ( device-based and self-reported ) were collected at baseline , after the 24-week intervention and at one year post-baseline . PA was measured by pedometer , accelerometer and question naire . Results Post-intervention physical activity changes were mediated by coping with relapse , changes in social norm , and social modeling from family members ( p ≤ 0.05 ) . One-year physical activity changes were mediated by coping with relapse , changes in social support from family and self-efficacy towards physical activity barriers ( p ≤ 0.05 ) Conclusions For patients with type 2 diabetes , initiatives to increase their physical activity could usefully focus on strategies for resuming regular patterns of activity , on engaging family social support and on building confidence about dealing with actual and perceived barriers to activity .
