Neighbourhood Walkability

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: An infrequently studied question is how the objective measurement of neighborhood walkability modulates physical activity changes during a physical activity intervention program in older adults. We assessed the influence of objectively assessed neighborhood walkability inside the city limits of Palma de Mallorca on the change in physical activity during the intervention program used in the ongoing PREvención con DIeta MEDiterránea (PREDIMED)-Plus trial, a multicenter randomized trial primarily designed to evaluate the long-term impact of an intensive lifestyle intervention on cardiovascular events. Method: The present study involved 228 PREDIMED-Plus senior participants aged between 55 to 75, recruited in Palma de Mallorca (Spain). Overweight/obese adults with the metabolic syndrome were randomized to an intensive weight-loss lifestyle intervention or a control group. A walkability index was calculated within 1 km buffers around each participant’ baseline home address. Physical activity was assessed using the validated REGICOR Short Physical Activity Questionnaire and accelerometer, at baseline and at 2 follow-up visits (six-months and one-year later). Generalised Additive Mixed Models (GAMMs) were fitted to estimate the association between the neighborhood walkability index and changes in physical activity during follow-up in both the intervention and control group. Results: After one-year of intervention, higher neighborhood walkability (1 z-score increment) was positively and significantly associated with moderate-to-vigorous accelerometer assessed physical activity duration, (ß = 3,44; 95% CI = 0.52;6.36 minutes per day). When analyses were stratified by intervention arm, the association was only significant in the intervention group (ß = 6.357; 95% CI = 2.07;10.64 minutes per day) (p for interaction = 0.055). There were no statistically significant associations between neighborhood walkability and self-reported leisure-time physical activity nor brisk walking duration. Conclusions: The results indicate that the walkability of the neighborhood could support a physical activity intervention, helping to maintain or increase older adults’ physical activity.

Step Counts

Purpose – The purpose of this paper is to ascertain the effect of a physical activity intervention using a combination of Facebook and standing banners on improvements in metabolic syndrome. Design/methodology/approach – In all, 120 (82.8 per cent) government employees with metabolic syndrome completed the programme. A Lifecorder e-STEP accelerometer (Suzuken Company Limited, Nagoya, Japan) was utilized to quantify physical activity. Metabolic syndrome was defined according to “Harmonized” definition at baseline, post-intervention and follow-up. Findings – There were significantly higher step counts in the intervention group as compared to the control group over time. There were significant within-group differences in the step count at the baseline, post-intervention and follow-up assessments (p < 0.001) in both the intervention and control groups. The step count of the intervention group increased by 4,522 steps in the post-intervention assessment compared to the assessment at baseline. The step count of the intervention group in the follow-up assessment was lower than in the post-intervention assessment, but it was still 2,126 steps higher than at baseline. For control group, the difference between the post-intervention assessment and the assessment at baseline was 520 steps per day, while the difference between the follow-up assessment and assessment at baseline was 379 steps per day. The greatest decrease in the percentage of metabolic syndrome was observed in the intervention group, with a reduction of 88.6 per cent in the post-intervention assessment as compared to that at baseline. Research limitations/implications – Future studies should incorporate measures which will be of interest to employers. Greater understanding and assessment of desirable employer-related outcomes are warranted, such as decreased job stress, turnover, absenteeism and improved job satisfaction, productivity and exploration of how these associated with physical activity. Practical implications – The findings show that delivering information on physical activity through an easily implemented and low-cost physical activity intervention via a combination of Facebook and standing banners was successful in improving step counts and metabolic parameters among individuals with metabolic syndrome. Social implications – The findings draw on supporting evidence for advocacy, which is about influencing the larger environment of public policy, and raising awareness of a single programme is insufficient to create lasting social change. Public policy must be shaped in a way that will sustain change across institutions. Originality/value – Despite the well-documented health benefits of physical activity, a growing number of people not achieving the recommended levels of physical activity necessary for good health. Importantly, the study provides a new insight on lifestyle-based physical activity interventions capable of improving step counts and metabolic parameters.

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.

Objectives. The aim of this study was to explore social engagement and social comparisons as mechanisms to increase physical activity among older adults. Methods. Participants (N = 60, mean age = 65.7) were randomly assigned to one of two conditions. Participants in the treatment condition used the application to track their daily walking steps and interact via text messages with their group members for 4 weeks. Participants in the control group used the application only to track their own walking steps. Outcome variables included mean weekly steps, exercise self-efficacy, and social engagement. Results. The results revealed that participants in the experimental condition significantly increased their mean weekly steps and social engagement from the pretest to the posttest whereas the control group did not. These effects were maintained at the 1-month follow up. Discussion. The study expands our understanding of the motivational role of social engagement and social comparison in increasing PA among older adults.

Appetite Control

Background: The effect of physical activity and exercise on hunger and satiety has been well-studied in younger adults, but the influence of aging is less understood. While some evidence suggests that acute bouts of exercise induce a compensatory eating drive, long-term activity may improve satiety sensitivity. The objective of this study was to investigate the effects of exercise on appetite in older adults.Methods: We systematically reviewed available literature investigating the effect of exercise on appetite in older adults adults (CRD42020208953). PubMed, PsycINFO, Academic Search Complete, the Sports Medicine &amp; Education Index, and Web of Science, were searched for peer-reviewed articles published in English with no date restriction. Included studies implemented a primary exercise or physical activity intervention with a control group, on a generally healthy population ≥60 years of age. Selected studies included at least one appetite outcome. Risk of bias was assessed using the 11-point Physiotherapy Evidence Database (PEDro) tool. Standardized mean difference summary statistics (Hedge's g effect sizes) and 95% confidence intervals were reported.Results: We identified 15 reports (13 studies) which met all inclusion criteria (5 resistance training, 3 aerobic, 6 mixed modalities). Studies included 443 participants (Age = 68.9 ± 5.2, 82.3% female) and had generally “good” bias scores (PEDro = 6.4 ± 0.88). Random effects meta-analyses revealed that the exercising group showed statistically significant reductions in glucose [SMD = −0.34 (95% CI: −0.67, −0.02), p &lt; 0.05, PEDro =6.4 ± 0.45] and leptin [SMD = −0.92 (95% CI: −1.28, −0.57), p &lt; 0.00001, PEDro = 6.2 ± 0.75].Discussion: This systematic review revealed that exercise and physical activity may modulate resting hunger and satiety in older adults. Decreases in fasting leptin and glucose hormones suggest that exercise promotes satiety sensitivity in adults aged 60+. This review highlights that engaging in exercise and activity programs may provide a meaningful avenue for improving chronic and functional disease burden in later life by promoting appetite control and balanced energy intake. Recommendations for future research include investigations of appetite in response to varied exercise modalities within more diverse and representative samples of older adults.

BACKGROUND The McMaster Optimal Aging Portal (the Portal) was launched in 2014 as a knowledge translation (KT) tool to increase access to evidence-based health information. OBJECTIVE The purpose of this study was to understand if and how dissemination of mobility information through the Portal impacts physical activity (PA) in older adults. METHODS In this randomized controlled trial, participants (n=510) were assigned to a 12-week mobility-focused KT intervention or self-serve control group. The intervention included weekly email alerts and a study-specific social media hashtag linking to mobility-focused Portal materials. The control group was able to access the Portal on their own but did not receive targeted KT strategies. Participants completed questionnaires (including the Rapid Assessment of Physical Activity to quantify PA) at baseline, end of the study, and 3-month follow-up. RESULTS Participants were predominantly female (430/510, 84.3%), mean age 64.7 years, with no baseline differences between groups. Over half (277/510, 54.3%) of the participants were classified as “active” at baseline. There was no significant between-group difference in the PA category. Overall, both groups increased their PA with improvements maintained at 3-month follow-up (<i>P</i>&lt;.001). In planned subgroup analyses, the KT intervention had a significant effect for those with poor or fair baseline self-rated health (<i>P</i>=.03). CONCLUSIONS No differences were found between those who received the targeted intervention and a control group with self-serve access to the Portal, except in subgroups with low self-rated health. Both groups did report increases in PA that were sustained beyond participation in a research study. Findings suggest that different KT strategies may be needed for different types of users, with more intense interventions being most impactful for certain groups (ie, those with lower self-rated health).

Abstract Objectives Findings are mixed regarding the potential to improve older adults’ cognitive ability via training and activity interventions. One novel sensitive outcome may be intraindividual variability (IIV) in cognitive speed, or moment-to-moment changes in a person’s performance. The present article evaluated if participants who participated in a moderate physical activity intervention showed a reduction in IIV, compared with a successful aging education control group. Method For approximately 2.6 years, sedentary adults aged 70–90 years participated in the Lifestyle Interventions and Independence for Elders (LIFE) Study (n = 1,635), a multisite Phase 3 randomized controlled trial to reduce major mobility disability. They completed 4 reaction time tests at baseline and at approximately 24 months post-test. Results Analyses were conducted following both the intent-to-treat principle and complier average casual effect modeling. Results indicated that participants in the physical activity group did not show a reduction in their IIV. Discussion The lack of a significant reduction in IIV may be due to the mild nature of the physical activity program and the cognitively healthy sample. It is also possible that other types of lifestyle activity interventions (e.g., social and cognitive engagement) can elicit reductions in IIV for older adults.
