Differences in Older Adults Walking Football Initiation and Maintenance Influences Across Respondent Characteristics: A Cross-Sectional Survey. J Aging Phys Act 2022; 30:936-949. [PMID: 35219276 DOI: 10.1123/japa.2021-0305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 12/21/2021] [Accepted: 01/20/2022] [Indexed: 11/18/2022]
Abstract
Despite health benefits gained from physical activity and sport participation, older adults are less likely to be active. This study investigates what influences 50- to 75-year-olds (N = 439) to initiate and maintain walking football, across gender, socioeconomic status, number of health conditions, and physical activity level. It also considers relationships between participant characteristics and influences, and intentions to play after a forced break (COVID-19). Results of a U.K. online cross-sectional survey found those with two or more health conditions rated social influences significantly higher in initiation and maintenance than participants with no health conditions. Multiple regression analysis found a positive walking football culture, and perceived use of maintenance resources contributed significantly to intentions to return to play after COVID-19 restrictions eased. Practitioners should consider providing opportunities for social connection, foster a positive walking football culture, and encourage players to utilize maintenance resources (e.g., scheduling sessions) in older adult walking football sessions.

Abstract
The objective of this study was to examine sources (friends, family, church members, and pastors) and type (positive or negative) of social support and their association with eating and physical activity behaviors. Study participants consisted of 41 African-American adults (78% female), with an average age of 43.5 years (standard deviation = 15.7). Participants were recruited from churches in southwest, Ohio. Mean comparisons showed family members, and friends had the highest positive and negative social support scores for healthy eating and physical activity. Pastors and church members received the lowest social support scores related to these behaviors. Using a linear regression analysis, social support in the form of physical activity rewards from family members was positively associated with fruit and vegetable consumption after adjusting for gender, age, education level, and church location. Based on these findings, future research should continue examining how different social support sources and types influence physical activity and healthy eating behaviors among African-Americans.

Abstract
OBJECTIVE To assess the maintenance of physical activity (PA) and health gains among participants in a class-based (CB) or home-based (HB) PA intervention over a 12-month study period. METHODS A total of 172 adults aged 50 years and older were randomly allocated to either a CB or an HB intervention, each involving an intensive 3-month phase with a 9-month follow-up period. Measures at baseline, 3, 6, and 12 months included self-reported PA and health, body mass index, waist circumference (WC), blood pressure, cardiovascular endurance (6-min walk test), physical function, and functional fitness (senior fitness test). Outcomes were analyzed using generalized estimating equations. RESULTS Maximum improvement was typically observed at 3 or 6 months followed by a modest diminution, with no differences between groups. For body mass index, waist circumference, 6-min walk test, and senior fitness test, there was progressive improvement through the study period. Greater improvement was seen in the CB group compared with the HB group on three items on the senior fitness test (lower body strength and endurance [29% vs. 21%, p < .01], lower body flexibility [2.8 cm vs. 0.4 cm, p < .05], and dynamic agility [14% vs. 7%, p < .05]). CONCLUSION The interventions were largely comparable; thus, availability, preferences, and cost may better guide program choice.

Abstract
BACKGROUND Remote and web 2.0 interventions for promoting physical activity (PA) are becoming increasingly popular but their ability to achieve long term changes are unknown. OBJECTIVES To compare the effectiveness of remote and web 2.0 interventions for PA promotion in community dwelling adults (aged 16 years and above) with a control group exposed to placebo or no or minimal intervention. SEARCH METHODS We searched CENTRAL, MEDLINE, EMBASE, CINAHL, and some other databases (from earliest dates available to October 2012). Reference lists of relevant articles were checked. No language restrictions were applied. SELECTION CRITERIA Randomised controlled trials (RCTs) that compared remote and web 2.0 PA interventions for community dwelling adults with a placebo or no or minimal intervention control group. We included studies if the principal component of the intervention was delivered using remote or web 2.0 technologies (for example the internet, smart phones) or more traditional methods (for example telephone, mail-outs), or both. To assess behavioural change over time, the included studies had a minimum of 12 months follow-up from the start of the intervention to the final results. We excluded studies that had more than a 20% loss to follow-up if they did not apply an intention-to-treat analysis. DATA COLLECTION AND ANALYSIS At least two authors independently assessed the quality of each study and extracted the data. Non-English language papers were reviewed with the assistance of an interpreter who was an epidemiologist. Study authors were contacted for additional information where necessary. Standardised mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for the continuous measures of self-reported PA and cardio-respiratory fitness. For studies with dichotomous outcomes, odds ratios and 95% CIs were calculated. MAIN RESULTS A total of 11 studies recruiting 5862 apparently healthy adults met the inclusion criteria. All of the studies took place in high-income countries. The effect of the interventions on cardiovascular fitness at one year (two studies; 444 participants) was positive and moderate with significant heterogeneity of the observed effects (SMD 0.40; 95% CI 0.04 to 0.76; high quality evidence). The effect of the interventions on self-reported PA at one year (nine studies; 4547 participants) was positive and moderate (SMD 0.20; 95% CI 0.11 to 0.28; moderate quality evidence) with heterogeneity (I2 = 37%) in the observed effects. One study reported positive results at two years (SMD 0.20; 95% CI 0.08 to 0.32; moderate quality evidence). When studies were stratified by risk of bias, the studies at low risk of bias (eight studies; 3403 participants) had an increased effect (SMD 0.28; 95% CI 0.16 to 0.40; moderate quality evidence). The most effective interventions applied a tailored approach to the type of PA and used telephone contact to provide feedback and to support changes in PA levels. There was no evidence of an increased risk of adverse events (seven studies; 2892 participants). Risk of bias was assessed as low (eight studies; 3060 participants) or moderate (three studies; 2677 participants). There were no differences in effectiveness between studies using different types of professionals delivering the intervention (for example health professional, exercise specialist). There was no difference in pooled estimates between studies that generated the prescribed PA using an automated computer programme versus a human, nor between studies that used pedometers as part of their intervention compared to studies that did not. AUTHORS' CONCLUSIONS We found consistent evidence to support the effectiveness of remote and web 2.0 interventions for promoting PA. These interventions have positive, moderate sized effects on increasing self-reported PA and measured cardio-respiratory fitness, at least at 12 months. The effectiveness of these interventions was supported by moderate and high quality studies. However, there continues to be a paucity of cost effectiveness data and studies that include participants from varying socioeconomic or ethnic groups. To better understand the independent effect of individual programme components, longer term studies, with at least one year follow-up, are required.

Abstract
BACKGROUND Face-to-face interventions for promoting physical activity (PA) are continuing to be popular but their ability to achieve long term changes are unknown. OBJECTIVES To compare the effectiveness of face-to-face interventions for PA promotion in community dwelling adults (aged 16 years and above) with a control exposed to placebo or no or minimal intervention. SEARCH METHODS We searched CENTRAL, MEDLINE, EMBASE, CINAHL, and some other databases (from earliest dates available to October 2012). Reference lists of relevant articles were checked. No language restrictions were applied. SELECTION CRITERIA Randomised controlled trials (RCTs) that compared face-to-face PA interventions for community dwelling adults with a placebo or no or minimal intervention control group. We included studies if the principal component of the intervention was delivered using face-to-face methods. To assess behavioural change over time the included studies had a minimum of 12 months follow-up from the start of the intervention to the final results. We excluded studies that had more than a 20% loss to follow-up if they did not apply an intention-to-treat analysis. DATA COLLECTION AND ANALYSIS At least two authors independently assessed the quality of each study and extracted data. Non-English language papers were reviewed with the assistance of an interpreter who was an epidemiologist. Study authors were contacted for additional information where necessary. Standardised mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for continuous measures of self-reported PA and cardio-respiratory fitness. For studies with dichotomous outcomes, odds ratios (ORs) and 95% CIs were calculated. MAIN RESULTS A total of 10 studies recruiting 6292 apparently healthy adults met the inclusion criteria. All of the studies took place in high-income countries. The effect of interventions on self-reported PA at one year (eight studies; 6725 participants) was positive and moderate with significant heterogeneity (I² = 74%) (SMD 0.19; 95% CI 0.06 to 0.31; moderate quality evidence) but not sustained in three studies at 24 months (4235 participants) (SMD 0.18; 95% CI -0.10 to 0.46). The effect of interventions on cardiovascular fitness at one year (two studies; 349 participants) was positive and moderate with no significant heterogeneity in the observed effects (SMD 0.50; 95% CI 0.28 to 0.71; moderate quality evidence). Three studies (3277 participants) reported a positive effect on increasing PA levels when assessed as a dichotomous measure at 12 months, but this was not statistically significant (OR 1.52; 95% CI 0.88 to 2.61; high quality evidence). Although there were limited data, there was no evidence of an increased risk of adverse events (one study; 149 participants). Risk of bias was assessed as low (four studies; 4822 participants) or moderate (six studies; 1543 participants). Any conclusions drawn from this review require some caution given the significant heterogeneity in the observed effects. Despite this, there was some indication that the most effective interventions were those that offered both individual and group support for changing PA levels using a tailored approach. The long term impact, cost effectiveness and rates of adverse events for these interventions was not established because the majority of studies stopped after 12 months. AUTHORS' CONCLUSIONS Although we found evidence to support the effectiveness of face-to-face interventions for promoting PA, at least at 12 months, the effectiveness of these interventions was not supported by high quality studies. Due to the clinical and statistical heterogeneity of the studies, only limited conclusions can be drawn about the effectiveness of individual components of the interventions. Future studies should provide greater detail of the components of interventions, and assess impact on quality of life, adverse events and economic data.

Abstract
BACKGROUND Face-to-face interventions for promoting physical activity (PA) are continuing to be popular as remote and web 2.0 approaches rapidly emerge, but we are unsure which approach is more effective at achieving long term sustained change. OBJECTIVES To compare the effectiveness of face-to-face versus remote and web 2.0 interventions for PA promotion in community dwelling adults (aged 16 years and above). SEARCH METHODS We searched CENTRAL, MEDLINE, EMBASE, CINAHL, and some other databases (from earliest dates available to October 2012). Reference lists of relevant articles were checked. No language restrictions were applied. SELECTION CRITERIA Randomised trials that compared face-to-face versus remote and web 2.0 PA interventions for community dwelling adults. We included studies if they compared an intervention that was principally delivered face-to-face to an intervention that had principally remote and web 2.0 methods. To assess behavioural change over time, the included studies had a minimum of 12 months follow-up from the start of the intervention to the final results. We excluded studies that had more than a 20% loss to follow-up if they did not apply an intention-to-treat analysis. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed the quality of each study and extracted the data. Non-English language papers were reviewed with the assistance of an interpreter who was an epidemiologist. Study authors were contacted for additional information where necessary. Standardised mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for continuous measures of cardio-respiratory fitness. MAIN RESULTS One study recruiting 225 apparently healthy adults met the inclusion criteria. This study took place in a high-income country. From 27,299 hits, the full texts of 193 papers were retrieved for examination against the inclusion criteria. However, there was only one paper that met the inclusion criteria. This study reported the effect of a PA intervention on cardio-respiratory fitness. There were no reported data for PA, quality of life, or cost effectiveness. The difference between the remote and web 2.0 versus face-to-face arms was not significant (SMD -0.02; 95% CI -0.30 to 0.26; high quality evidence). The risk of bias in the included study was assessed as low, and there was no evidence of an increased risk of adverse events. AUTHORS' CONCLUSIONS There is insufficient evidence to assess whether face-to-face interventions or remote and web 2.0 approaches are more effective at promoting PA.

Abstract
BACKGROUND Retirement represents a major transitional life stage in middle to older age. Changes in physical activity typically accompany this transition, which has significant consequences for health and well-being. The aim of this systematic review was to evaluate the evidence for the effect of interventions to promote physical activity in adults aged 55 to 70 years, focusing on studies that reported long-term effectiveness. This systematic review adheres to a registered protocol (PROSPERO CRD42011001459). METHODS Randomized controlled trials of interventions to promote physical activity behavior with a mean/median sample age of 55 to 70 years, published between 2000 and 2010, were identified. Only trials reporting the long-term effect (≥ 12 months) on objective or self-reported physical activity behavior were included. Trials reporting physiological proxy measures of physical activity were excluded. Meta-analyses were conducted when trials provided sufficient data and sensitivity analyses were conducted to identify potential confounding effects of trials of poor methodological quality or with attrition rates ≥ 30%. RESULTS Of 17,859 publications identified, 32 were included which reported on 21 individual trials. The majority of interventions were multimodal and provided physical activity and lifestyle counselling. Interventions to promote physical activity were effective at 12 months (standardized mean difference (SMD) = 1.08, 95% confidence interval (CI) = 0.16 to 1.99, pedometer step-count, approximating to an increase of 2,197 steps per day; SMD = 0.19, 95% CI = 0.10 to 0.28, self-reported physical activity duration outcome), but not at 24 months based on a small subset of trials. There was no evidence for a relationship between intervention effectiveness and mode of delivery or number of intervention contacts; however, interventions which involved individually tailoring with personalized activity goals or provision of information about local opportunities in the environment may be more effective. CONCLUSIONS Interventions in adults aged 55 to 70 years led to long term improvements in physical activity at 12 months; however, maintenance beyond this is unclear. Identified physical activity improvements are likely to have substantial health benefits in reducing the risk of age-related illnesses. These findings have important implications for community-based public health interventions in and around the retirement transition.

Abstract
BACKGROUND Patients seeking treatment for hearing-related communication difficulties are often disappointed with the eventual outcomes, even after they receive a hearing aid or a cochlear implant. One approach that audiologists have used to improve communication outcomes is to provide auditory training (AT), but compliance rates for completing AT programs are notoriously low. PURPOSE The primary purpose of the investigation was to conduct a patient-based evaluation of the benefits of an AT program, I Hear What You Mean, in order to determine how the AT experience might be improved. A secondary purpose was to examine whether patient perceptions of the AT experience varied depending on whether they were trained with a single talker's voice or heard training materials from multiple talkers. RESEARCH DESIGN Participants completed a 6 wk auditory training program and were asked to respond to a posttraining questionnaire. Half of the participants heard the training materials spoken by six different talkers, and half heard the materials produced by only one of the six talkers. STUDY SAMPLE Participants included 78 adult hearing-aid users and 15 cochlear-implant users for a total of 93 participants who completed the study, ages 18 to 89 yr (M = 66 yr, SD = 16.67 yr). Forty-three females and 50 males participated. The mean better ear pure-tone average for the participants was 56 dB HL (SD = 25 dB). INTERVENTION Participants completed the single- or multiple-talker version of the 6 wk computerized AT program, I Hear What You Mean, followed by completion of a posttraining questionnaire in order to rate the benefits of overall training and the training activities and to describe what they liked best and what they liked least. DATA COLLECTION AND ANALYSIS After completing a 6 wk computerized AT program, participants completed a posttraining questionnaire. Seven-point Likert scaled responses to whether understanding spoken language had improved were converted to individualized z scores and analyzed for changes due to AT. Written responses were coded and categorized to consider both positive and negative subjective opinions of the AT program. Regression analyses were conducted to examine the relationship between perceived effort and perceived benefit and to identify factors that predict overall program enjoyment. RESULTS Participants reported improvements in their abilities to recognize spoken language and in their self-confidence as a result of participating in AT. Few differences were observed between reports from those trained with one versus six different talkers. Correlations between perceived benefit and enjoyment were not significant, and only participant age added unique variance to predicting program enjoyment. CONCLUSIONS Participants perceived AT to be beneficial. Perceived benefit did not correlate with perceived enjoyment. Compliance with computerized AT programs might be enhanced if patients have regular contact with a hearing professional and train with meaning-based materials. An unheralded benefit of AT may be an increased sense of control over the hearing loss. In future efforts, we might aim to make training more engaging and entertaining, and less tedious.

Abstract
ISSUE ADDRESSED The Physical Activity and Nutrition Program for Seniors (PANS) program aimed to increase levels of physical activity and improve the diet of insufficiently active community-based seniors aged 60 to 70 years using a range of strategies. Comprehensive process evaluation was used to determine the suitability and appropriateness of the resources and effectiveness of the strategies. METHOD Process evaluation data (qualitative and quantitative) were collected on the program strategies and resources throughout, and at the conclusion of the intervention period. RESULTS The program strategies/resources were found to be relevant to the population, assisting participants to increase their level of physical activity and improve their diet. Participants reported that the program resources were suitable for their age-group (84%), encouraged them to think about physical activity (78%), and nutrition (70%). Participants reported that they used the pedometer (91%) and recorded daily steps (78%). Moreover, the provision of group guides facilitated individuals to set and achieve personal goals. CONCLUSION The PANS strategies and resources were appropriate, which supported the seniors in identifying, establishing, and achieving their physical activity and nutrition goals. Minor refinements of the program were recommended based on the findings.

Abstract
The acceptability of a high-calorie-expenditure (HCE) exercise program in older coronary heart disease patients participating in a behavioral weight-control program was evaluated. Seventy-four overweight patients (median age 63 yr) were randomly assigned to a 5-mo intervention of HCE exercise (3,000–3,500 kcal/wk daily walking) or standard cardiac-rehabilitation (CR) exercise (700–800 kcal/wk). Both groups received counseling to achieve a dietary caloric deficit of 3,500 kcal/ wk. Assessments at baseline and 5 mo included self-reported measures of quality of life and psychosocial variables. The HCE group experienced significantly greater weight loss (8.2 ± 4 vs. 3.7 ± 5 kg,p< .001). Changes from baseline to 5 mo on scores of physical, emotional, and social functioning were greater for the HCE than CR group (p< .05). HCE exercise also resulted in greater positive change in exercise enjoyment (p= .05), which was mediated by weight change. Even high-risk older adults can be successful in an HCE exercise program and experience no adverse physical or emotional changes.

Abstract
OBJECTIVES To build upon state-of-the-art theory and empirical data to estimate the strength of multiple mediators of the efficacious Keep Active Minnesota (KAM) physical activity (PA) maintenance intervention. METHODS The total, direct, and indirect effects through which KAM helped randomized participants (KAM n = 523; UC n = 526) maintain moderate or vigorous PA (MVPA) for up to 2 years were estimated using structural equation modeling. RESULTS Multiple mediators explained half (beta = .052, P = .13) of the effect of KAM on MVPA (beta = .105, P = .004). Self-efficacy was the upstream variable in 2 endogenously mediated effects, and the self-concept mediator emerged as the strongest predictor of MVPA. CONCLUSIONS KAM positively impacted self-efficacy, which was associated with PA enjoyment, integration into the self-concept, and PA maintenance. Successful long-term PA maintenance appears to be influenced by multiple small interrelated mediational pathways. Future research evaluating maintenance models should specify recursive relationships among mediators and outcomes.

OBJECTIVE To evaluate the efficacy at 6-, 12-, and 24-month follow-up of Keep Active Minnesota (KAM), a telephone and mail-based intervention designed to promote physical activity (PA) maintenance among currently active adults age 50 to 70. METHOD Participants who reported having recently increased their MVPA to a minimum of 2d/wk, 30 min/bout, (N=1049) were recruited in 2004 and 2005 from one large managed care organization in Minnesota, and randomly assigned to either treatment (KAM; N=523), or Usual Care (UC; N=526) with PA assessed using the CHAMPS questionnaire, and expressed as kcal/wk energy expenditure. RESULTS We find a sustained, significant benefit of the intervention at 6, 12 and 24 months. kcal/wk expenditure in moderate or vigorous activities was higher at 6 (p<.03, Cohen's d(6m)=.16), 12 (p<.04, d(12 m)=.13) and 24 months (p<.01, d(24 m)=.16) for KAM participants, compared to UC participants. CONCLUSIONS The KAM telephone- and mail-based PA maintenance intervention was effective at maintaining PA in both the short-term (6 months) and longer-term (12 and 24 months) relative to usual care.

Abstract
OBJECTIVE To assess the representativeness of older adults recruited to a physical activity maintenance RCT by conducting sequential comparisons to characterize study sample composition changes occurring between sampling frame construction and study enrollment. METHOD Study subjects (N = 1049) were 50 to 70 year old men and women who had increased physical activity within the past year recruited from a Midwestern managed care organization. RESULTS Those responding to an initial mailed screener differed on demographic, behavioral, and SES characteristics from those not responding. Compared with ineligibles, eligible individuals were significantly younger, more highly educated, and more likely to report improved health in the prior year. Compared with eligible individuals who did not enroll, enrollees had generally higher education and income. CONCLUSIONS Physical activity promotion programs in older adults may have limited reach and substantial volunteer bias. Additional strategies to increase the reach of physical activity interventions into the target population are needed.
