IntroductionKnee osteoarthritis (OA) is the most common chronic illness among older adults. Up to the submission date of this protocol, there are no published UK studies reporting the efficacy of a combined intervention programme of physical activity and dietary restriction on the musculoskeletal function of obese older adults with knee OA in spite of the clinical recommendation for exercise and diet for people with knee OA. The aim of this study is to assess the feasibility and acceptability of a combined dietary restriction and physical activity intervention programme and collect preliminary data.Method and analysisThis single-arm intervention study is scheduled to begin in September 2017 and conclude in November 2018. It will take place at the Royal Orthopaedic Hospital (ROH), Birmingham and the School of Sport, Exercise and Rehabilitation Sciences (SportExR), University of Birmingham. Participants will receive a physiotherapy usual care programme for knee OA for 1 month, after which they will continue to exercise in their local gym/leisure facility for 3 months. Participants will also follow dietary restriction throughout the 4-month intervention. Mixed analysis techniques will be used to analyse the quantitative and qualitative outcome measures.Ethics and disseminationIt is approved by ROH R&D Foundation Trust and the Health Research Authority. The Consort Guidelines and checklist will be reviewed prior to generating any publications for the trial to ensure they meet the standards required for submission to high-quality peer-reviewed journals.Trial registration numberISRCTN12906938.

Abstract Background While urban built environments might promote active ageing, an infrequently studied question is how the neighbourhood walkability modulates physical activity changes during a physical activity intervention programme in older adults. We assessed the influence of objectively assessed neighbourhood walkability on the change in physical activity during the intervention programme used in the ongoing PREvención con DIeta MEDiterránea (PREDIMED)-Plus trial. Method The present study involved 228 PREDIMED-Plus senior participants aged between 55 and 75, recruited in Palma de Mallorca (Spain). Overweight/obese older adults with metabolic syndrome were randomised to an intensive weight-loss lifestyle intervention or a control group. A walkability index (residential density, land use mix, intersections density) was calculated using geographic information systems (1 km sausage-network buffer). Physical activity was assessed using accelerometer and a validated questionnaire, at baseline and two follow-up visits (6-months and 1-year later). Generalised additive mixed models were fitted to estimate the association between the neighbourhood walkability index and changes in physical activity during follow-up. Results Higher neighbourhood walkability (1 z-score increment) was associated with moderate-to-vigorous accelerometer assessed physical activity duration, (β = 3.44; 95% CI = 0.52; 6.36 min/day). When analyses were stratified by intervention arm, the association was only observed in the intervention group (β = 6.357; 95% CI = 2.07;10.64 min/day) (P for interaction = 0.055). Conclusions The results indicate that the walkability of the neighbourhood could support a physical activity intervention, helping to maintain or increase older adults’ physical activity.

Abstract Background Supervised physical activity interventions improve functional health during cancer survivorship, but remain costly and inaccessible for many. We previously reported on the benefits of a DVD-delivered physical activity program (FlexToBa™) in older adults. This is a secondary analysis of the intervention effects among cancer survivors in the original sample. Methods Low active, older adults who self-reported a history of cancer (N = 46; M time since diagnosis = 10.7 ± 9.4 years) participated in a 6-month, home-based physical activity intervention. Participants were randomized to either the DVD-delivered physical activity program focused on flexibility, toning, and balance (FlexToBa™; n = 22) or an attentional control condition (n = 24). Physical function was assessed by the Short Physical Performance Battery (SPPB) at baseline, end of intervention, and at 12 and 24 months after baseline. Results Repeated measures linear mixed models indicated a significant group*time interaction for the SPPB total score (β = − 1.14, p = 0.048), driven by improved function from baseline to six months in the FlexToBa™ group. The intervention group also had improved balance (β = − 0.56, p = 0.041) compared with controls. Similar trends emerged for the SPPB total score during follow-up; the group*time interaction from 0 to 12 months approached significance (β = − 0.97, p = 0.089) and was significant from 0 to 24 months (β = − 1.84, p = 0.012). No significant interactions emerged for other outcomes (ps > 0.11). Conclusions A DVD-delivered physical activity intervention designed for cancer-free older adults was capable of eliciting and maintaining clinically meaningful functional improvements in a subgroup of cancer survivors, with similar effects to the original full sample. These findings inform the dissemination of evidence-based physical activity programs during survivorship. Trial registration ClinicalTrials.govNCT01030419. Registered 11 December 2009

IntroductionPhysical activity is an integral part of healthy ageing, yet the majority of older adults 65+ years are not sufficiently active. Web-based physical activity interventions hold much promise to reach older adults. Preliminary evidence suggests that web-based interventions with tailored advice and Fitbits may be well suited for older adults.Methods and analysisThis study aims to test the effectiveness of ‘Active for Life’, a 12-week computer-tailored web-based physical activity intervention using Fitbits for older adults. We will recruit 300 participants who will be randomly assigned to one of three trial arms: (1) web-based physical activity intervention with tailored advice only, (2) web-based physical activity intervention with tailored advice and Fitbit or (3) a wait-list control. The primary outcome, objective moderate to vigorous physical activity (MVPA) and secondary outcomes of objective sedentary behaviour, objective sleep, quality of life, social support, physical function and satisfaction with life will be assessed at baseline and week 12. The secondary outcomes of self-reported physical activity, sitting time and sleep will be assessed at baseline, week 6, 12 and 24. Website usability and participant satisfaction will be assessed at week 12 and website usage and intervention fidelity will be assessed from week 1 to 24. Intention-to-treat linear mixed model analyses will be used to test for group (tailoring only, tailoring +Fitbit, control) differences on changes in the main outcome, MVPA and secondary outcomes. Generalised linear models will be used to compare intervention groups (tailoring only, tailoring +Fitbit) on website usability, participant satisfaction, website usage and intervention fidelity.Ethics and disseminationThe study has received ethics approval from the Central Queensland University Human Research Ethics Committee (H16/12-321). Study outcomes will be disseminated through peer-reviewed publications and academic conferences and used to inform improvements and dissemination of a tailored, web-based physical activity intervention for adults 65+ years.Trial registration numberAustralian and New Zealand Clinical Trials Registry Number: ACTRN12618000646246

BACKGROUND Despite the crucial role of regular physical activity (PA) for preventing chronic non-communicable diseases, fewer than half of older adults in Germany engage in the recommended levels of endurance training. OBJECTIVE The aim of this study was to compare acceptance and effectiveness of two interventions (web- vs. print-based) for PA promotion among initially inactive community-dwelling older adults aged 60 years and above in a nine-month randomized trial with a cross-over design. METHODS Participants were recruited offline and randomized to one of the following interventions for self-monitoring PA: (a) a print-based intervention (PRINT n=113), (b) a web-based intervention (WEB, n=129). Thirty percent (n=38) of those in group (b) received a PA tracker in addition to WEB (WEB+, (c)). After randomization, participants and researchers were not blinded. Participants’ intervention preferences at baseline were assessed retrospectively. All intervention groups were offered ten weekly face-to-face group sessions led by trained assistants. Afterwards, participants could choose to stay in their group or cross over to one of the other groups and group sessions were continued monthly for another six months. Three-dimensional accelerometers to assess PA and sedentary behavior (SB) at baseline (T0), three-month (T1) and nine-month follow-ups (T2) were employed. Adherence to PA recommendations, attendance of group sessions, and acceptance of the interventions were assessed via self-administered paper-based questionnaires. Linear mixed models were used to calculate differences in moderate-to-vigorous PA (MVPA) and SB between time points and intervention groups. RESULTS One-hundred and ninety-five participants completed T1. Only n=1 changed from WEB to PRINT and n=15 moved from PRINT to WEB (WEB-WEB: n=103, PRINT-PRINT: n=76) when offered to cross over at T1. One-hundred and sixty participants completed T2. MVPA in min per day increased between baseline and T1, but these within-group changes in time disappeared after adjusting for covariates. MVPA decreased by 9 min per day between baseline and T2 (βtime = -9.37, 95% CI: [-18.58; -0.16]), regardless of intervention group (WEB vs. PRINT: βgroup*time = -3.76, 95% CI: [-13.33; 5.82], WEB+ vs. PRINT: βgroup*time = 1.40, 95% CI: [-11.04; 13.83]). Nineteen percent of the participants met PA recommendations at T0, 20% at T1, and 20% at T2. For SB, there were no significant group differences and group-by-time interactions, neither at T1 nor at T2. Intervention acceptance was generally high. Use of intervention material was high to moderate at T1 (e.g., the PA diary was used by over 65% at least once a week) and decreased by T2 (40-50% in PRINT and in WEB used the PA diary at least once a week, and 58% in WEB+). CONCLUSIONS Despite high levels of acceptance of web- and print-based interventions for PA promotion and little movement between groups at T1, when given the choice, participation was not associated with increases in PA or decreases in SB over time.

Abstract Background Adequate physical activity (PA) is considered essential in diabetes management. However, evidence on the best method of promoting PA within diabetes care is inconclusive. The current work identifies perceptions on the acceptability of Intervention Group Participants (IGP) and Project Officers (POs) about the “MOVEdiabetes” intervention programme aimed at increasing PA in adults with type 2 diabetes in Oman (a retrospectively registered trial). Methods The “MOVEdiabetes” programme (PA consultations, pedometers and WhatsApp messages) was delivered by the POs (primary health care practitioners) in four primary care centres within a one-year cluster randomised control trial. Recruitment and retention were measured from trial attendance records. Programme satisfaction, appropriateness, and content suitability were assessed using exit surveys for both the IGP (interview based) and POs (self-administered). Open text questions on perceptions to the study programme were also included. Results Participants were randomised to an intervention group (IG, n = 122) or comparison group (CG, n = 110). The overall retention rate at three and 12 months was 92.7% [110(90.2%) IG vs 105(95.5%) CG] and 75% [82(67.2%) IG vs 92(83.6%) CG] respectively. Most (n = 14, 87.5%) POs and more than half (n = 49, 59.8%) IGP perceived the programme as very appropriate and many reported that they were “quite/ very satisfied” with the programme (n = 16, 100% PO’s and n = 71, 86.6% IGP). Two thirds (n = 55, 66.0%) of IGP were very/quite likely to recommend the programme to others. PA consultations, use of pedometers and Whatsapp messages were well perceived by all. Participants recommended the inclusion of dietary advice and PA promotion for the general public. Exploring PA facilities within the community was suggested by POs. Conclusions The “MOVEdiabetes” programme achieved a high retention rate and was perceived as satisfactory and appropriate. Results from this study suggest that it is worthwhile exploring the use of the “MOVEdiabetes” programme in clinical practice and further community links.
