Community health worker perspectives: examining current responsibilities and strategies for success.

BACKGROUND: Community health worker (CHW) interventions have demonstrated positive impacts globally, with the COVID-19 pandemic further highlighting the potential of CHWs at the frontline to support prevention, outreach, and healthcare delivery. As the workforce expands, understanding the work and capabilities of CHWs is key to design successful interventions. This study examines the perspectives of experienced CHWs in Chicago about their current work and strategies for success. METHODS: As part of a community-academic partnership in Chicago, semi-structured interviews were completed with individuals who held positions aligned with CHW. Interviews were conducted between January and April 2022. Questions focused on participants' work and factors contributing to their effectiveness to gain insights into workforce strategies for success to be applied in healthcare and community settings. De-identified transcripts were analyzed using inductive reasoning with codes organized into themes and subthemes under two domains identified a priori. The themes informed a logic model focused on the early stages to support the success of CHWs in their role. RESULTS: Fourteen individuals participated in the study. The two predetermined domains in this study were: current work of CHWs and strategies for CHWs to be successful. Five themes were identified about CHWs' current work: providing services, building alliances with clients, establishing and maintaining collaborations, collecting data, and experiencing challenges in role. From their perspectives, all these responsibilities enhance client care and support workforce sustainability efforts. Five themes emerged about strategies for the success of CHWs: background of CHWs, champions to support work of CHWs, materials to perform work of CHWs, preparation for CHW role, and characteristics of CHWs. Participants described key traits CHWs should possess to be hired, individuals who can champion and advocate for their work, and specific materials needed to fulfill responsibilities. They reported that training and familiarity with the community were integral to developing and refining the qualities and skills necessary to be effective in their role. CONCLUSION: CHWs play an increasingly important role in enhancing healthcare delivery and improving health outcomes. This study offers a framework for policymakers, communities, and organizations to utilize for preparing CHWs to succeed in their roles.

A Model of Community Health Worker Integration into Schools: Community-based Participatory Research in Action.

BACKGROUND: Schools are rich sites for collaborations between health and educational sectors. OBJECTIVES: To identify lessons learned from formation of a community-academic partnership and application of community-based participatory research (CBPR) to develop a model that integrates community health workers into schools. METHODS: Individuals from an academic medical center, a large public school district, and a community-based research institute applied CBPR principles to reimagine schools as a place for improving the health of children. LESSONS LEARNED: Three lessons emerged. Leveraging each team member's expertise centered the partnership on community strengths, co-learning, and stakeholder engagement. Adherence to CBPR's principles of power sharing and equity helped navigate the challenges of collaboration between large institutions. Early focus on sustainability helped address unexpected issues, build capacity, and boost advocacy. CONCLUSIONS: This partnership demonstrates how CBPR fosters conditions in which equitable partnerships between research institutions and public schools can thrive to promote childhood health.

The REtirement in ACTion exercise programme and its effects on elements of long term functionality in older adults.

Background: The prevention of mobility-related disability amongst adults is a global healthcare priority. Cost-effective community-based strategies to improve physical function and independence in older adults with mobility limitations are needed. This study investigated the effectiveness of the REtirement in ACTion (REACT) exercise intervention on individual markers of physical function at 6-and 12-months. Methods: The REACT multicentre randomised controlled trial assigned 777 older adults (female, 514; male 263) (mean age 77·6 [SD 6·8] years) with reduced lower limb physical functioning (Short Physical Performance Battery [SPPB] score 4-9) to receive brief healthy ageing advice or a 12-month, group-based, multimodal exercise programme delivered in local communities. Estimated differences in the three individual component scores of the SPPB (strength, balance, gait speed) and physical functional outcomes recorded at 6- and 12-months were assessed. Results: The intervention group demonstrated significant improvements in strength (OR = 1.88, 95% CI = 1.36-2.59, p < 0.001) and balance (OR = 1.96, 95% CI = 1.39-2.67, p < 0.001) at 12-months, but not in gait speed (OR = 1.32, 95% CI = 0.91-1.90, p = 0.139). In comparison to the control group, at six-and 12-months, the intervention group reported statistically significant improvements in Mobility Assessment Tool-Short Form (MAT-SF), physical component score from SF-36 questionnaire, and strength and endurance items of subjectively reported physical activity (PASE 10-item). Greater than 75% adherence (attending ≥48 of the 64 exercise sessions delivered in 12-months) was associated with superior functional outcomes. Conclusion: The REACT exercise programme provides local, regional and national service providers with an effective solution to increase muscle strength and balance in older adults at risk of mobility disability.

Community health workers' perspectives on integrating into school settings to support student health.

Introduction: While schools represent key venues for supporting health, they continue to experience gaps in health resources. The integration of community health workers (CHWs) into schools has the potential to supplement these resources but has been underexplored. This study is the first to examine perspectives of experienced CHWs about how CHWs can be applied in school settings to support student health. Methods: This qualitative study involved conducting semi-structured interviews focused on implementation of CHWs in schools with individuals who held positions aligned with the CHW scope of work. De-identified transcripts were analyzed, and codes were organized into domains and themes. Results: Among 14 participants, seven domains emerged about the implementation of CHWs in schools: roles and responsibilities, collaborations, steps for integration, characteristics of successful CHWs, training, assessment, and potential challenges. Participants shared various potential responsibilities of school-based CHWs, including educating on health topics, addressing social determinants of health, and supporting chronic disease management. Participants emphasized the importance of CHWs building trusting relationships with the school community and identified internal and external collaborations integral to the success of CHWs. Specifically, participants indicated CHWs and schools should together determine CHWs' responsibilities, familiarize CHWs with the school population, introduce CHWs to the school community, and establish support systems for CHWs. Participants identified key characteristics of school-based CHWs, including having familiarity with the broader community, relevant work experience, essential professional skills, and specific personal qualities. Participants highlighted trainings relevant to school-based CHWs, including CHW core skills and health topics. To assess CHWs' impact, participants proposed utilizing evaluation tools, documenting interactions with students, and observing indicators of success within schools. Participants also identified challenges for school-based CHWs to overcome, including pushback from the school community and difficulties related to the scope of work. Discussion: This study identified how CHWs can have a valuable role in supporting student health and the findings can help inform models to integrate CHWs to ensure healthy school environments.

Cost-effectiveness of a physical activity and behaviour maintenance programme on functional mobility decline in older adults: an economic evaluation of the REACT (Retirement in Action) trial.

BACKGROUND: Mobility limitations in older populations have a substantial impact on health outcomes, quality of life, and social care costs. The Retirement in Action (REACT) randomised controlled trial assessed a 12-month community-based group physical activity and behaviour maintenance intervention to help prevent decline in physical functioning in older adults at increased risk of mobility limitation. We aimed to do an economic evaluation of the REACT trial to investigate whether the intervention is cost-effective. METHODS: In this health economic evaluation, we did cost-effectiveness and cost-utility analyses of the REACT programme versus standard care on the basis of resource use, primary outcome, and health-related quality-of-life data measured in the REACT trial. We also developed a decision analytic Markov model that forecasts the mobility of recipients beyond the 24-month follow-up of the trial and translated this into future costs and potential benefit to health-related quality of life using the National Health Service and Personal Social Services perspective. Participants completed questionnaire booklets at baseline, and at 6, 12, and 24 months after randomisation, which included a resource use questionnaire and the EQ-5D-5L and 36-item short-form survey (SF-36) health-related quality-of-life instruments. The cost of delivering the intervention was estimated by identifying key resources, such as REACT session leader time, time of an individual to coordinate the programme, and venue hire. EQ-5D-5L and SF-36 responses were converted to preference-based utility values, which were used to estimate quality-adjusted life-years (QALYs) over the 24-month trial follow-up using the area-under-the-curve method. We used generalised linear models to examine the effect of the REACT programme on costs and QALYs and adjust for baseline covariates. Costs and QALYs beyond 12 months were discounted at 3·5% per year. This is a pre-planned analysis of the REACT trial; the trial itself is registered with ISRCTN (ISRCTN45627165). FINDINGS: The 12-month REACT programme was estimated to cost £622 per recipient to deliver. The most substantial cost components are the REACT session leader time (£309 per participant), venue hire (£109), and the REACT coordinator time (£80). The base-case analysis of the trial-based economic evaluation showed that reductions in health and social care usage due to the REACT programme could offset the REACT delivery costs (£3943 in the intervention group vs £4043 in the control group; difference: -£103 [95% CI -£695 to £489]) with a health benefit of 0·04 QALYs (0·009-0·071; 1·354 QALYs in the intervention group vs 1·314 QALYs in the control group) within the 24-month timeframe of the trial. INTERPRETATION: The REACT programme could be considered a cost-effective approach for improving the health-related quality of life of older adults at risk of mobility limitations.

Effect of a physical activity and behaviour maintenance programme on functional mobility decline in older adults: the REACT (Retirement in Action) randomised controlled trial.

BACKGROUND: Mobility limitations in old age can greatly reduce quality of life, generate substantial health and social care costs, and increase mortality. Through the Retirement in Action (REACT) trial, we aimed to establish whether a community-based active ageing intervention could prevent decline in lower limb physical functioning in older adults already at increased risk of mobility limitation. METHODS: In this pragmatic, multicentre, two-arm, single-blind, parallel-group, randomised, controlled trial, we recruited older adults (aged 65 years or older and who are not in full-time employment) with reduced lower limb physical functioning (Short Physical Performance Battery [SPPB] score 4-9) from 35 primary care practices across three sites (Bristol and Bath; Birmingham; and Devon) in England. Participants were randomly assigned to receive brief advice (three healthy ageing education sessions) or a 12-month, group-based, multimodal physical activity (64 1-h exercise sessions) and behavioural maintenance (21 45-min sessions) programme delivered by charity and community or leisure centre staff in local communities. Randomisation was stratified by site and adopted a minimisation approach to balance groups by age, sex, and SPPB score, using a centralised, online, randomisation algorithm. Researchers involved in data collection and analysis were masked but participants were not because of the nature of the intervention. The primary outcome was change in SPPB score at 24 months, analysed by intention to treat. This trial is registered with ISRCTN, ISRCTN45627165. FINDINGS: Between June 20, 2016, and Oct 30, 2017, 777 participants (mean age 77·6 [SD 6·8] years; 66% female; mean SPPB score 7·37 [1·56]) were randomly assigned to the intervention (n=410) and control (n=367) groups. Primary outcome data at 24 months were provided by 628 (81%) participants (294 in the control group and 334 in the intervention group). At the 24-month follow-up, the SPPB score (adjusted for baseline SPPB score, age, sex, study site, and exercise group) was significantly greater in the intervention group (mean 8·08 [SD 2·87]) than in the control group (mean 7·59 [2·61]), with an adjusted mean difference of 0·49 (95% CI 0·06-0·92; p=0·014), which is just below our predefined clinically meaningful difference of 0·50. One adverse event was related to the intervention; the most common unrelated adverse events were heart conditions, strokes, and falls. INTERPRETATION: For older adults at risk of mobility limitations, the REACT intervention showed that a 12-month physical activity and behavioural maintenance programme could help prevent decline in physical function over a 24-month period.

Caregiver Perceptions of Children's Psychological Well-being During the COVID-19 Pandemic.

Importance: Understanding youth well-being during the COVID-19 pandemic can help appropriately allocate resources and inform policies to support youth. Objective: To examine caregiver-reported changes in the psychological well-being of their children 3 to 4 months after the start of COVID-19 stay-at-home orders, and to examine the association of caregiver-reported COVID-19 exposure and family stressors with caregiver perceptions of child psychological well-being. Design, Setting, and Participants: This survey study used an anonymous survey distributed via email from June 24 to July 15, 2020, to 350 000 families of students attending public schools in Chicago, Illinois. The a priori hypotheses were that caregivers would report worsening in child psychological well-being during the closure period compared with preclosure and that exposure to COVID-19-related stressors would be associated with a higher probability of worsening child psychological well-being. Data were analyzed from September 10, 2020, to March 15, 2021. Main Outcomes and Measures: Outcomes were 7 mental health concerns and 5 positive adjustment characteristics reported by caregivers using a retrospective pre-post design. COVID-19 exposure and family stressors were also reported by caregivers. Results: Among 350 000 families invited to participate, 32 217 caregivers (10 827 [39.3%] White, 8320 [30.2%] Latinx, 6168 [22.4%] Black; 2223 [8.1%] with multiple or other races/ethnicities) completed the survey on behalf of 49 397 children in prekindergarten through 12th grade. Child-specific outcomes were reported for 40 723 to 40 852 children depending on the specific question. The frequency of caregiver endorsement of youth mental health concerns ranged from 0.1 percentage point (suicidal ideation or self-harm, reported by 191 caregivers [0.5%] preclosure vs 246 caregivers [0.6%] during closure; P < .001) to 28.3 percentage points (loneliness, reported by 1452 caregivers [3.6%] preclosure vs 13 019 caregivers [31.9%] during closure; P < .001) higher after the end of in-person instruction compared with preclosure. Frequency of caregiver endorsement of youth positive adjustment characteristics ranged from -13.4 percentage points (plans for the future, reported by 18 114 caregivers [44.3%] preclosure vs 12 601 caregivers [30.9%] during closure; P < .001) to -30.9 percentage points (positive peer relationships, reported by 24 666 caregivers [60.4%] preclosure vs 19 130 caregivers [46.8%] during closure; P < .001) lower after the end of in-person instruction. Significant differences in COVID-19 exposure were observed across racial/ethnic (F3,27 534 = 614.8; P < .001) and household income strata (F5,27 506 = 842.0; P < .001). After accounting for covariates, all mental health concerns increased in probability (eg, angry: odds ratio, 1.55 [95% CI, 1.48-1.62]; P < .001) and all the positive adjustment characteristics decreased in probability (eg, hopeful or positive: odds ratio, 0.88 [95% CI, 0.84-0.92]; P < .001) as COVID-19 exposure and family stressors increased. Conclusions and Relevance: In this survey study of caregivers during the COVID-19 pandemic, COVID-19 and resulting exposure to stress were associated with worse youth psychological well-being, demonstrating the need for a comprehensive public health approach that prioritizes children's well-being and draws broad public attention to the mental health needs of youth.

Trends in School Attendance for Low-Income Children with Chronic Health Conditions: Results from a Randomized Controlled Trial.

BACKGROUND: In this study, we aimed to determine how school attendance changed over time for children on Medicaid with chronic health conditions enrolled in a comprehensive care coordination program called Coordinated HEalthcare for Complex Kids (CHECK). METHODS: Medicaid beneficiaries from one managed care organization were randomized into 2 arms: CHECK program services or usual care. The final sample was 1322. RESULTS: The mean age was 10.9 (SD = 3.7) years old and children were mostly non-Hispanic Black (62.6%) or Hispanic (34.9%). The median school attendance at baseline was 94.9% (IQR 88.9, 97.9); over one-fourth of children (28.4%) were chronically absent. School attendance was not associated with race/ethnicity, risk level, and health condition. In a model including a significant time/grade interaction, school attendance increased over time for children in pre-kindergarten (OR = 1.52, 95% CI: 1.38, 1.68; p < .001) and kindergarten to 5th grade (OR = 1.21, 95% CI: 1.17, 1.26; p < .001), and decreased for children in 6th to 8th grade (OR = 0.80, 95% CI: 0.77, 0.83; p < .001). No differences were seen in school attendance or chronic absenteeism associated with enrollment in the CHECK program. CONCLUSIONS: School attendance improved for most of the low-income children with chronic health conditions in our cohort, except for children in middle school.

Mobilising people as assets for active ageing promotion: a multi-stakeholder perspective on peer volunteering initiatives.

BACKGROUND: Successful peer volunteering is central to many community-based, active ageing initiatives. This study synthesises the perspectives of a range of stakeholders involved in peer volunteering initiatives and provides recommendations as to how peer volunteers can be effectively mobilised as community assets. METHODS: An evidence synthesis of qualitative data from (a) the evaluation of ACE (Active, Connected, Engaged), a feasibility trial of a peer volunteering active ageing intervention, and (b) interviews with volunteers and managers of third sector organisations providing peer volunteering programmes. Data were analysed using directed content analysis. RESULTS: Ten managers, 22 volunteers and 20 ACE participants were interviewed. The analysis identified six main themes, 33 higher and 22 sub themes. Main themes were: (i) Motives, (ii) Benefits, (iii) Skills and Characteristics, (iv) Challenges, (v) Training Needs, (vi) Recruitment and Retention. Altruism, changes in life circumstances, opportunities to reconnect with the community and personal fulfilment were the main reasons for volunteering. Volunteering was described as being personally rewarding, an avenue to acquire new skills and knowledge, and an opportunity for increased social connections and physical activity. Good peer volunteers are committed, reliable, have a good sense of humour, good interpersonal skills and are able to relate to participants. When pairing volunteers with participants, shared interests and geographical proximity are important to consider. Clarity of role, level of time commitment, regular feedback, recognition of effort and strong networks for on-going support are important strategies to facilitate volunteer retention. CONCLUSIONS: The findings of this study support the value of peer volunteering as a strategy for mobilising community assets in promoting active ageing. To ensure success and longevity, these schemes require appropriate funding and efficient administrative support.

The Tribulations of Trials: Lessons Learnt Recruiting 777 Older Adults Into REtirement in ACTion (REACT), a Trial of a Community, Group-Based Active Aging Intervention Targeting Mobility Disability.

BACKGROUND: Challenges of recruitment to randomized controlled trials (RCTs) and successful strategies to overcome them should be clearly reported to improve recruitment into future trials. REtirement in ACTion (REACT) is a United Kingdom-based multicenter RCT recruiting older adults at high risk of mobility disability to a 12-month group-based exercise and behavior maintenance program or to a minimal Healthy Aging control intervention. METHODS: The recruitment target was 768 adults, aged 65 years and older scoring 4-9 on the Short Physical Performance Battery (SPPB). Recruitment methods include the following: (a) invitations mailed by general practitioners (GPs); (b) invitations distributed via third-sector organizations; and (c) public relations (PR) campaign. Yields, efficiency, and costs were calculated. RESULTS: The study recruited 777 (33.9% men) community-dwelling, older adults (mean age 77.55 years (SD 6.79), mean SPPB score 7.37 (SD 1.56)), 95.11% white (n = 739) and broadly representative of UK quintiles of deprivation. Over a 20-month recruitment period, 25,559 invitations were issued. Eighty-eight percent of the participants were recruited via GP invitations, 5.4% via the PR campaign, 3% via word-of-mouth, and 2.5% via third-sector organizations. Mean recruitment cost per participant was £78.47, with an extra £26.54 per recruit paid to GPs to cover research costs. CONCLUSIONS: REACT successfully recruited to target. Response rates were lower than initially predicted and recruitment timescales required adjustment. Written invitations from GPs were the most efficient method for recruiting older adults at risk of mobility disability. Targeted efforts could achieve more ethnically diverse cohorts. All trials should be required to provide recruitment data to enable evidence-based planning of future trials.

Feasibility Trial Evaluation of a Peer Volunteering Active Aging Intervention: ACE (Active, Connected, Engaged).

BACKGROUND: ACE (Active, Connected, Engaged) is a theory-informed, pragmatic intervention using peer volunteering support to promote active ageing in socially disengaged, inactive older adults. This study aimed to establish ACE's feasibility and acceptability. METHODS: Fifty-four older adults were recruited as either peer volunteers (activators; n = 15) or participants (ACEs; n = 39). Participants were randomized to one-to-one support from an activator (ACEs-Intervention [ACEs-I]) or a waiting-list control group (ACEs-Control [ACEs-C]). Activators supported ACEs-I to get out more and engage with local activities. Objectively measured physical activity (PA), lower limb function, and number of out of house activities were assessed at baseline and post-intervention. A mixed-methods process evaluation assessed changes in confidence to get out and about, social support, autonomy, competence, and relatedness. RESULTS: Eighty-two percent of ACEs (mean age = 73.7 years [SD 7.3]) and all activators completed assessments at both baseline and post-intervention (6 months). ACEs-I reported more out of house activities (M [SD] = 6.34 [4.15]). ACEs-I increased physical function post-intervention (M [SD] = 9.8 [2.3]). ACEs-I reported improved well-being and vitality and increased confidence to get out and about, confidence in the face of specific barriers, knowledge of local initiatives, and perceived social support post-intervention. Activators, although sufficiently active at baseline, increased their PA further. ACE was well-accepted and easy to deliver. CONCLUSIONS: ACE is an acceptable and feasible intervention for helping socially disengaged older people to get out and about more, improve their confidence, and engage more with their community.

Increased risk of intraventricular hemorrhage in low birth weight infants with aortic coarctation.

Objective: To determine if there is an association between aortic coarctation (CoA) and intraventricular hemorrhage (IVH) in low birth weight (LBW) infants that may justify earlier intervention. While there is an increasing number of reports of successful early CoA intervention in LBW infants, there are no data to justify this approach.Material and methods: Retrospective review of the University Health System Consortium Clinical Data Base/Resource Manager, a national hospital discharge database. LBW (≤2 kg) infants, with and without IVH and isolated CoA were identified; IVH was stratified into low (grade 1 or 2) and high (grade 3 or 4) severity. Odds ratios were calculated for any, low and high-grade IVH with CoA.Results: Forty-six thousand and twenty LBW infants were identified; 3716 (8.1%) had IVH, 3001 (81%) with low, and 724 (19%) with high severity. Sixty-four infants had CoA, 13 had associated IVH (10 with low and three with high severity). The odds ratio for any IVH with CoA was 2.91 (95% CI 1.58-5.35), low severity 2.77 (95% CI 1.41-5.46) and high severity 3.45 (95% CI 1.07-11.07).Conclusions: In conclusion, this large retrospective database review found that LBW infants with CoA may be at increased risk of IVH. Further study is needed to determine if earlier catheter- or surgical-based intervention for CoA could reduce the risk of IVH in this population.

Invasive Cardiac Procedures in Interstage Single Ventricle Patients in Emergent Hospitalizations.

Single ventricle congenital heart disease (SV CHD) patients are at risk of morbidity and mortality between the first and second palliative surgical procedures (interstage). When these patients present acutely they often require invasive intervention. This study sought to compare the outcomes and costs of elective and emergent invasive cardiac procedures for interstage patients. Retrospective review of discharge data from The Vizient Clinical Data Base/Resource Manager™, a national health care analytics platform. The database was queried for admissions from 10/2014 to 12/2017 for children 1-6 months old with ICD-9 or ICD-10 codes for SV CHD who underwent invasive cardiac procedures. Demographics, length of stay (LOS), complication rate, in-hospital mortality and direct costs were compared between elective and emergent admissions using t test or χ2, as appropriate. The three most frequently performed procedures were also compared. 871 admissions identified, with 141 (16%) emergent. Age of emergent admission was younger than elective (2.9 vs. 4 months p < 0.001). Emergent admissions including cardiac catheterization or superior cavo-pulmonary anastomosis had longer LOS (58.7 vs. 25.8 day, p < 0.001 and 54.8 vs .22.6 days, p < 0.001) and higher costs ($134,774 vs. $84,253, p = 0.013 and $158,679 vs. $81,899, p = 0.017). Emergent admissions for interstage SV CHD patients undergoing cardiac catheterization or superior cavo-pulmonary anastomosis are associated with longer LOS and higher direct costs, but with no differences in complications or mortality. These findings support aggressive interstage monitoring to minimize the need for emergent interventions for this fragile patient population.

We will present an overview of the central approaches focusing on pluripotent stem cell-derived cells, mechanisms of action, autologous vs. allogeneic cell approaches, immunologic modulation, and safety considerations. We will outline the progress that has been made to-date and define the areas that still need to be investigated in order to advance the field.

Associations between walking parameters and subsequent sleep difficulty in older adults: A 2-year follow-up study.

PURPOSE: This 2-year follow-up study aimed to examine the associations between total volume, frequency, duration, and speed of walking with subsequent sleep difficulty in older adults. METHODS: A total of 800 older adults aged 65 years and over participated in the first survey in 2012 and 511 of them were followed 2 years later. The 5-item Athens Insomnia Scale (AIS-5) was used to measure sleep difficulty. Frequency, duration, and speed of outdoor walking were self-reported. Walking speed was assigned a metabolic equivalent value (MET) from 2.5 to 4.5. Total walking volume in MET-h/week was calculated as frequency × duration × speed. Negative binomial regressions were performed to examine the associations between volume and components of walking with subsequent sleep difficulty with covariates of age, sex, education, marital status, living arrangement, smoking, alcohol consumption, mental health, Charlson Index, exercise (excluding walking), and sleep difficulty at baseline. RESULTS: Participants with low walking volume had a higher level of sleep difficulty 2 years later compared with those with high walking volume (incident rate ratios = 1.61, p = 0.004). When speed, frequency, and duration of walking were simultaneously entered into 1 model, only walking speed was significantly associated with subsequent sleep difficulty (after the model was adjusted for covariates and baseline sleep difficulty). Sensitivity analyses showed that walking duration emerged as a significant predictor among 3 walking parameters, with 2-year changes of sleep scores as dependent variable. CONCLUSION: Total amount of walking (especially faster walking and lasting for more than 20 min) is associated with less subsequent sleep difficulty after 2 years among older adults.

Participant and Public Involvement in Refining a Peer-Volunteering Active Aging Intervention: Project ACE (Active, Connected, Engaged).

Background: Evidence for the health benefits of a physically active lifestyle among older adults is strong, yet only a small proportion of older people meet physical activity recommendations. A synthesis of evidence identified "best bet" approaches, and this study sought guidance from end-user representatives and stakeholders to refine one of these, a peer-volunteering active aging intervention. Methods: Focus groups with 28 older adults and four professional volunteer managers were conducted. Semi-structured interviews were conducted with 9 older volunteers. Framework analysis was used to gauge participants' views on the ACE intervention. Results: Motives for engaging in community groups and activities were almost entirely social. Barriers to participation were lack of someone to attend with, lack of confidence, fear of exclusion or "cliquiness" in established groups, bad weather, transport issues, inaccessibility of activities, ambivalence, and older adults being "set in their ways". Motives for volunteering included "something to do," avoiding loneliness, the need to feel needed, enjoyment, and altruism. Challenges included negative events between volunteer and recipient of volunteering support, childcare commitments, and high volunteering workload. Conclusion: Peer-volunteering approaches have great potential for promotion of active aging. The systematic multistakeholder approach adopted in this study led to important refinements of the original ACE intervention. The findings provide guidance for active aging community initiatives highlighting the importance of effective recruitment strategies and of tackling major barriers including lack of motivation, confidence, and readiness to change; transport issues; security concerns and cost; activity availability; and lack of social support.
