ObjectivesThe objective was to investigate the feasibility and usability of electronic momentary assessment, goal-setting and personalized phone-calls on adherence to a 12-week self-conducted interval walking training (IWT) program, delivered by the InterWalk smartphone among patients with type 2 diabetes (T2D).MethodsIn a two-arm pilot randomized controlled trial (Denmark, March 2014 to February 2015), patients with T2D (18–80 years with a Body Mass Index of 18 and 40 kg/m2) were randomly allocated to 12 weeks of IWT with (experimental) or without additional support (control). The primary outcome was the difference between groups in accumulated time of interval walking training across 12 weeks. All patients were encouraged to use the InterWalk application to perform IWT for ≥90 minute/week. Patients in the experimental group made individual goals regarding lifestyle change. Once a week inquiries about exercise adherence was made using an ecological momentary assessment (EMA). In case of consistent self-reported non-adherence, the patients would receive a phone-call inquiring about the reason for non-adherence. The control group did not receive additional support. Information about training adherence was assessed objectively. Usability of the EMA was assessed based on response rates and self-reported satisfaction after 12-weeks.ResultsThirty-seven patients with T2D (66 years, 65% female, hemoglobin 1Ac 50.3 mmol/mol) where included (n = 18 and n = 19 in experimental and control group, respectively). The retention rate was 83%. The experimental group accumulated [95%CI] 345 [-7, 698] minutes of IWT more than the control group. The response rate for the text-messages was 83% (68% for males and 90% for females). Forty-one percent of the experimental and 25% of the control group were very satisfied with their participation.ConclusionThe combination inquiry about adherence using EMA, goal-setting with the possibility of follow-up phone calls are considered feasible interventions to attain training adherence when using the InterWalk app during a 12-week period in patients with T2D. Some uncertainty about the effect size of adherence remains.Trial registrationClinicaltrials.gov NCT02089477

Objectives The objective of this systematic review and meta-analysis was to examine the effectiveness of remote feedback intervention compared with standardized treatment on physical activity levels in persons with type 2 diabetes. Further, to investigate the influence of the length of intervention, number of contacts, study size, delivery of feedback, and preliminary face-to-face sessions. Methods A systematic literature search was conducted in May 2017, with a priori defined eligibility criteria: randomized controlled trials investigating remote feedback interventions in adult persons with type 2 diabetes, using physical activity as outcome. The effect size was calculated as standardized mean difference (SMD) and was pooled in a meta-analysis using a random-effects model. Meta-regression analyses were performed to examine if the observed effect size could be attributed to study- or intervention characteristics using these as covariates. Results The literature search identified 4455 articles of which 27 met the eligibility criteria. The meta-analysis including a total of 4215 participants found an overall effect size in favour of remote feedback interventions compared to standardized treatment, SMD = 0.33 (95% CI: 0.17 to 0.49), I = 81.7%). Analyses on study characteristics found that the effect on physical activity was only influenced by study size, with a larger effect in small studies. Conclusion Adding remote feedback to standardized treatments aimed at increasing physical activity in persons with type 2 diabetes showed a small to moderate additional increase in physical activity levels.

Objectives: The risk of musculoskeletal pain increases when there is an imbalance between work demands and physical capacity. Work in elder care requires frequent periods of high mechanical loading. Body weight can further amplify this load, while muscle strength may lessen the relative strain on the musculoskeletal system. The purpose of this study was to assess the correlation between body composition, muscular strength and localized musculoskeletal pain intensity in overweight female health care professionals. Methods: A sample of 139 overweight female health care professionals working in elder care were included in the analyses. Associations between BMI, fat percentage, waist circumference, muscle strength and localized pain intensity were assessed using Kendall’s rank correlation. Results: Significant associations were found between musculoskeletal pain in the right shoulder and BMI (rτ=0.194; p=0.035), whereas upper back pain was associated with fat percentage and waist circumference (rτ=0.212; p=0.023 and rτ=0.212; p=0.024, respectively). Conclusions: Results indicate high BMI, fat percentage, and waist circumference may be contributing factors of localized musculoskeletal pain intensity of the upper body in overweight female health care professionals. These results may help guide the design of future workplace health promotion programmes.
