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 .
Increasing Physical Activity in Belgian Type 2 Diabetes Patients: a Three-Arm Randomized Controlled Trial
Background Pedometer-based physical activity programs have been typically delivered in a group format by a behavioral expert . An alternative strategy that builds on existing interactions is delivery through individual consultation by a general practitioner ( GP ) . These two delivery strategies have not been directly compared . Purpose To compare effectiveness of a 12-week physical activity ( PA ) intervention for type 2 diabetes patients delivered by a trained GP via an individual consultation or as group delivery by a behavioral expert . MethodS ixty-seven primary care participants ( mean age = 67.4 years , 70 % male ) from three Belgian general practice s were r and omized into three different treatment arms : ( 1 ) individual consultation ( n = 22 ) with three PA contacts with the patient 's GP ; ( 2 ) group counseling ( n = 21 ) with three PA group sessions delivered by a behavioral expert ; and ( 3 ) a control arm ( n = 24 ) receiving no intervention .  Participant inclusion criteria were ≤80 years ; 25–35 kg/m² ; ≤12 % HbA1c and reporting no PA limitations . Outcome measures were pedometer-determined steps/day , self-reported PA , and health parameters ( weight , body mass index , waist circumference , total cholesterol , fasting glucose , and HbA1c ) . Results Group counseling participants increased 1,706 steps/day over baseline significantly ( p ≤ 0.05 ) more than other treatment arms . Moreover , they increased their self-reported PA ( + 82 min/day ) , while control arm participants showed a decrease in PA ( p ≤ 0.05 ) . Participants of the individual consultation had a decrease in waist circumference ( −1.4 cm ) and HbA1c ( −0.32 % ) and a lower increase in total cholesterol ( + 7.2 mg/dl ) compared to the other treatment arms ( all p ≤ 0.05 ) . Conclusion Group counseling in type 2 diabetes patients improved PA , whereas individual consultations had an impact on some health outcomes on the short-term
