Physical activity is medicine for older adults

"Now I Am Walking Toward Health": A Qualitative Study About the Outcomes of Physical Activity Participation That Matter to Older Adults

BACKGROUND/OBJECTIVES

Randomized controlled trials that deliver physical activity interventions have demonstrated benefits for older adults across numerous health outcomes. However, too little attention has been directed to ensuring that such trials are measuring patient-relevant outcomes. To support outcome selection for future trials, the objective of this study was to understand what outcomes related to their physical activity participation older adults find important.

METHODS

We conducted 12 semistructured interviews with adults aged 65 years and older and analyzed interview transcripts with a reflexive thematic analysis.

RESULTS

Older adults desired diverse outcomes from their physical activity participation, ranging from generic (e.g., quality of life) to specific (e.g., leg strength). Relevant outcomes were classified under five themes: physical, clinical, social, psychological, and overarching, each with respective subthemes.

CONCLUSIONS

The outcomes that older adults found important were plentiful and rooted in a desire to improve their quality of life. Some of the outcome themes have been reported frequently in past trials (e.g., physical), but others have not (e.g., social). Future researchers should be aware of, and responsive to, the priorities of older adults when designing trials and defining outcomes. Significance/Implications: This study will help to improve outcome selection for future trials of physical activity with older adults. In alignment with a patient-oriented research philosophy, this study will also ground future outcome selection in the priorities of older adults.

Association of Daily Physical Activity With Motivation in Prefrail and Frail Older Adults Living in Retirement Communities

Older adults living in retirement communities are an understudied population, and the association between their motivation and daily physical activity is unknown. We recruited participants (n = 173) living in a retirement community who completed the Behavioral Regulation in Exercise Questionnaire-2 and wore an activPAL accelerometer to evaluate this relationship. Participants had a median age of 81 years and demonstrated low levels of daily activity with an average step count of 3,637 (±1,965) steps per day and 52 (±25) min of daily stepping time. External motivation was negatively associated with the square root of daily step count (β = -4.57; p < .001) and square root of daily stepping time (β = -0.49; p < .001). Older adults living in retirement communities demonstrated low levels of daily activity, with a negative association between external motivation and daily activity. Strategies are needed to make an active lifestyle supportive and enticing for older adults in these communities.

Participant Experiences With a Community-Based, "Older Adult" Walking Football Initiative in Australia: A Qualitative Exploration

Despite the growing popularity of walking sports, little is known about who is attracted to them, and what skills, motivations, and experiences encourage ongoing participation. The aim of this study was to gain an in-depth understanding of the phenomenon of walking football in Australia. The authors first conducted semistructured interviews with 53 older adults (M = 62.37 years, 30.19% female) participating in walking football in Australia. Next, they conducted thematic analysis to develop themes that represented participant perspectives. Results indicated that walking football led to several physical benefits, but the social and mental benefits seemed to be more closely associated with continued participation. The slower pace of walking football created a valuable option to engage in physical activity among those with injuries or severe health issues, as well as older adults concerned about injuries. The slower pace also shifted the focus of walking football away from fitness and ability, and toward technique and skill development, and this focus, along with the mix in abilities, led to informal coaching and mentoring roles which were highly valued among older participants. Participant views about competition in walking football were diverse, with some expressing a mild concern. Understanding such diverse experiences of walking football helps to better understand how different aspects of the sport influence the perceived benefits and likelihood of continuing for different people. Using these findings to further develop walking sports in Australia could have large impacts on the health and well-being of older people.

Nutrition and Physical Activity Education in Medical School: A Narrative Review

This review explores the diverse landscape of integrating nutrition and physical activity education into medical school curricula, focusing on the imperative role of physicians in promoting health through lifestyle changes. By examining global medical education structures, we uncovered disparities in nutrition and physical activity training, and highlighted the need for a shared framework to address international and regional challenges. Despite acknowledging the importance of both nutrition and physical activity, studies have consistently uncovered deficiencies in medical school curricula, especially in skills related to providing lifestyle advice and behavioral counseling. Survey studies among medical students have illuminated various perceptions and knowledge gaps, emphasizing the need for more comprehensive and mandatory nutrition and physical activity training. While acknowledging progress, challenges, such as time constraints, resource availability, and faculty expertise, persist. Integrating lifestyle education results in resistance, a demand for strategic communication, and faculty buy-ins. These findings underscore the importance of a holistic approach that balances theoretical knowledge, practical skills, and confidence that medical students need to promote effective nutrition and physical activity in healthcare.

The relationship between accelerometer-based physical activity, sedentary behavior, and seven common geriatric syndromes: a two-sample Mendelian randomization study

Introduction

To investigate the causal associations between accelerometer-based physical activity (PA), sedentary behavior (SB), and seven common geriatric syndromes (GSs) (frailty, falls, delirium, urinary incontinence, dysphagia, hearing loss, and visual impairment) by Mendelian randomization (MR) analysis.

Methods

Instrumental variables from a genome-wide association study were used for MR analysis. The exposure factors were three PA phenotypes (average acceleration, overall activity, and moderate-intensity activity) and one SB phenotype (SB). The outcome variables were seven common GSs. The inverse variance weighted (IVW) method was utilized for the primary MR analysis. Additionally, sensitivity, pleiotropy, and heterogeneity analyses were subsequently conducted to assess the robustness of the present study's findings.

Results

According to the primary MR results obtained using the IVW method, genetically predicted PA (average acceleration) decreased the risk of two GSs (frailty, p = 0.01; dysphagia, p = 0.03). Similarly, overall activity decreased the risk of two GSs (frailty, p = 0.01; delirium, p = 0.03), and moderate-intensity activity reduced the risk of three GSs (urinary incontinence, p = 0.04; hearing loss, p = 0.02; visual impairment, p = 0.01). Furthermore, SB was causally correlated with a greater risk for three GSs (frailty, p = 0.03; fall, p = 0.01; dysphagia, p = 0.04).

Conclusion

This study provided evidence that accelerometer-based PA may be causally associated with a lower risk of GSs, while SB may increase the risk of GSs.

Leisure-time physical activity as a key protective factor against cognitive decline in older adults: an isotemporal substitution analysis

This study aimed to test hypothesized effects of replacing sedentary behavior with moderate-to-vigorous physical activity, sleep, and different domains of physical activity by equivalent amounts on suggestive cognitive decline in an older adult population. This was a cross-sectional study including 473 older adults aged ≥ 60 years. Cognitive decline was assessed using the Mini-Mental Health Examination. Physical activity, its different domains and the time of exposure to sedentary behavior were assessed using the International Physical Activity Questionnaire. For data analysis, two isotemporal substitution models were constructed using Poisson regression. The first model tested the effect of sleep time, sedentary behavior, and moderate-to-vigorous physical activity on cognitive decline. The second model was used to determine the effect of physical activity domains (leisure, work, transport, and home), sleep time, and sedentary behavior on cognitive decline. Physical activity during leisure time was protective against cognitive decline among all domains tested, replacing sedentary behavior, sleep, and transport. Conversely, substitution of the leisure domain for sedentary behavior, sleep, and transport was considered a risk factor for cognitive decline. Leisure time proved to be a strong protective factor in reducing the risk of cognitive decline, and it is necessary to encourage and stimulate public policies that include it.

Exploration of the Determinants of Subjective Health and Depression Using Korean Longitudinal Study of Aging Data

Aging is an imperative issue in Korean society, and a healthy life is important for a better quality of life for older adults. Therefore, the purpose of this research was to investigate the determinants of subjective health and depression in middle-aged and elderly Korean individuals. This study used three attributes as the determinants of subjective health and depression, including the curve linear effect of medical expenses and eating-out expenses and the linear impact of regular exercise. We utilized the Korean Longitudinal Study of Aging (KLOSA) to determine the associations between five attributes: subjective health, depression, medical expenses, eating-out expenses, and regular exercise. Research panel data were employed as the data source. The study period was between 2018 and 2020. This research implemented various multiple linear panel regression econometric analysis instruments: ordinary least squares, random effects, and fixed effects. The mean age of survey participants was 72.10 years, and 35 percent of participants were female. The number of observations for data analysis was 7197. The results revealed that medical and eating-out expenses had a curved linear effect on subjective health and depression. Moreover, regular exercise positively affected subjective health and resulted in less depression. These findings may inform policy decisions that promote regular exercise and manage medical and eating-out expenses, thereby enhancing subjective health and mitigating depression.

Effect of Physical Activity on Association between COVID-19 and Personal Life in Community-Dwelling Older Adults

Our study investigated whether changes in physical activity due to COVID-19 mediate the association between quarantine or hospitalization due to COVID-19 and COVID-19 life impact score. A total of 154 participants (0.23%) were quarantined or hospitalized due to COVID-19. There were mediating effects of changes in physical activity due to COVID-19 (β = -1.63, 95% confidence interval = -0.77 to -2.42). This study suggests that measures to minimize lifestyle changes during the pandemic are required to reduce negative consequences.

Exercise Adherence in Older and Middle-Aged Adults With Coronary Artery Disease Before and During COVID-19

BACKGROUND

Regular exercise is advised for individuals given a diagnosis of cardiovascular disease. COVID-19 presented challenges to exercise adherence.

OBJECTIVE

The objective of this study was to determine long-term exercise adherence and whether individuals with cardiovascular disease adhered to American Heart Association/American College of Cardiology Foundation guidelines before and during the COVID-19 pandemic.

METHODS

This is an observational cross-sectional study in which men (73%) and women discharged from a multiwide hospital system after an acute coronary event were enrolled. Participants completed 3 questionnaires, including the Exercise Adherence Rating Scale.

RESULTS

Five hundred eighty-two individuals (mean [SD] age, 67 [9.8] years) completed the survey. Fifty-three percent of participants met minimum exercise guidelines during COVID-19. Exercise days per week decreased significantly during COVID-19 in women ( P = .013) but not significant for men ( P = .301). Categorized by age, the decrease was significant for middle-aged women ( P = .002), not older women ( P = .336). Men exercised more minutes per session ( P = .034), and had greater exercise adherence ( P = .003) and greater exercise intensity ( P < .001). Overall, women participated less in cardiac rehabilitation ( P = .046) and reported the greatest disparity in exercise adherence and intensity.

CONCLUSION

Exercise after an acute event is beneficial, and the percentage of individuals meeting recommended guidelines should be higher considering the relationship between exercise and the possibility of future cardiac events. On the basis of the many physical and mental benefits of maintaining exercise, healthcare practitioners are encouraged to screen all patients for exercise adherence with a major emphasis on educating women and older adults.

Moving together - benefits of an online dance program on physical and mental health for older women: an exploratory mixed-method study

BACKGROUND

Previous studies show that in-person dance training is a beneficial form of physical activity that involves mental, social, and physical dimensions. This exploratory study investigated the benefits of a 12-week online dance training intervention on mental and physical health outcomes for older women.

METHODS

A convergent parallel mixed-method design was used. Forty-five older adults (74.0 ± 5.3 yrs old, 44 women) were recruited through advertisements at activity and rehabilitation centers in the North Denmark region. The intervention consisted of two weekly 60-min classes of improvisation and salsa delivered online through video call applications. Changes in physical health outcomes (body mass and composition, resting blood pressure, Senior Fitness Test battery) and self-rated health and wellbeing (health-related quality of life (HRQOL), feelings of loneliness) were assessed prior to and after 12 weeks of dancing. Focus group interviews were conducted post-intervention to further explore the benefits as well as the participant's experience of the intervention. Thematic analysis of the qualitative data was conducted.

RESULTS

Thirty-two participants (all women) completed the study. Significant improvements in fitness were found for the number of arm curls performed (baseline: 12.3 ± 3.0; post-intervention: 13.7 ± 3.0, P = 0.005), 2-min step test performance (baseline: 66.5 ± 20.0 reps.; post-intervention: 73.8 ± 22.6 reps., P = 0.016), and chair sit-and-reach (baseline: 0.4 ± 11.3 cm; post-intervention: 5.5 ± 10.1 cm, P < 0.001). There was a significant increase in body mass from baseline to post-intervention (P < 0.015). The themes from the focus groups included (1) Participation, (2) Challenges, (3) Progression, (4) Motivation, (5) Perceived health and wellbeing, and (6) Online dance instruction. No significant changes were reported in HRQOL and loneliness from the quantitative data, although the qualitative data did reveal improved feelings of physical health and wellbeing.

CONCLUSIONS

The intervention improved several aspects of fitness in older women and improved the participants' perceptions of their own physical abilities and wellbeing. While most participants found the online intervention enjoyable, several participants missed the feedback from the instructors that naturally occurs with in-person instruction.

'Nih Waangkiny Kaadatjiny': 'Listening, learning and knowing': Stakeholders' perspectives about barriers and enablers to delivering a successful physical activity program for older Aboriginal people

There is limited evidence about how physical activity (PA) programs should be provided for older Aboriginal and Torres Strait Islander peoples. Recently two groups of Aboriginal Elders on Noongar Boodja (Country) in Western Australia participated in the Ironbark PA program.

ISSUE ADDRESSED

The objective of this study was to explore the views of key stakeholders about the barriers and enablers to delivering a successful PA program and provide feedback for future program delivery.

METHODS

The research took a 'Nih (listening), Waangkiny (learning), Kaadatjiny (knowing)' approach. The lead researcher, a Noongar Wadjuk woman, conducted semi-structured interviews (n = 17) with key stakeholders: Aboriginal and non-Aboriginal workers who assisted to deliver the program, and family and local members of the communities. Data were also collected through weekly program notes and researcher diary entries. Data were analysed thematically.

RESULTS

The overarching theme highlighted that stakeholders felt a sense of building a PA program that was culturally appropriate. They reflected that the program attracted older Aboriginal people because it was designed to make them feel welcomed with a sense of belonging. Five major themes were identified: Relationships, Belonging, Program structure, Benefits of the program and Future planning. Positive changes observed in Elders' health and well-being were a source of inspiration for team workers.

CONCLUSIONS

Key enablers to delivering a PA program for older Aboriginal people are building a culturally strong program that creates a sense of belonging for the participants. SO WHAT?: Practitioners who are planning PA programs for older Aboriginal people should prioritise the development of cultural safety and security.

Isotemporal substitution analysis of time between sleep, sedentary behavior, and physical activity on depressive symptoms in older adults: a cross-sectional study

BACKGROUND

Compared to young individuals, older adults participate more in sedentary behavior (SB) and less in physical activity (PA). These behaviors are associated with numerous adverse health factors.

OBJECTIVE

The purpose of the study was to examine the hypothetical effects of substituting time spent sleeping, performing SB, and performing moderate-to-vigorous physical activity (MVPA) on depressive symptomatology in older adults.

DESIGN AND SETTING

An analytical cross-sectional study employing exploratory survey methods was conducted in the city of Alcobaça in the state of Bahia, Brazil.

METHODS

The study included 473 older adults who answered a structured questionnaire during an interview. Exposure time to SB and PA level were assessed using the International Physical Activity Questionnaire, and depressive symptoms were analyzed using the short version of the Geriatric Depression Scale. An isotemporal replacement model was used to evaluate the effects of different SB sessions on depressive symptomatology.

RESULTS

An increase in the risk of depressive symptoms was observed when MVPA and sleep time were substituted for the same SB time at all times tested, with maximum values of 40% and 20%, respectively. Opposite substitution of MVPA and sleep time increments reduced the risk of depressive symptomatology by 28% and 17%, respectively.

CONCLUSIONS

The results of the present study indicate that replacing SB with the same amount of sleep or MVPA may reduce depressive symptoms. The longer the reallocation time, the greater are the benefits.

Classical Ballet for Women Aged Over 50 Years: Investigating Balance, Strength, and Range of Motion

Background: Regular exercise can mitigate the loss of strength, balance, and flexibility that contribute to age-related decline in physical function and mobility. However, traditional exercise interventions often report poor adherence rates. There is growing interest in classical ballet as an enjoyable exercise modality for adults in middle to late age. Classical ballet requires muscular strength, coordination, and flexibility. The current study investigated a classical ballet intervention on the balance, physical function, and range of motion of women aged over 50 years. Methods: Twenty-two healthy female participants (aged 56.2 (4.5) years (mean (SD)) completed a 10-week ballet intervention. Results: This single-arm study showed significant improvements (p<.05) in lower limb strength (measured by 5 times sit-to-stand and forward leap) and high adherence rates (95% adherence for participants who completed the intervention). No adverse events were reported. Improvements in balance were reported in the left leg only (as measured by center of pressure ellipse area in the parallel retiré condition). Conclusions: These results allude to the positive effects of ballet training on strength and balance in adults aged 50 years and over. High adherence rates suggest that ballet training was enjoyed and may thus be a long-term exercise modality for this population. Although this study was a single-arm design, it suggests promising results for future research wishing to evaluate the effectiveness of classical ballet training using randomized controlled trial designs.

Visual Impairment and Real-World Home Physical Activity With Home Environment in an Older Population

Importance

Physical activity levels are lower in visual impairment. However, additional factors, such as home environmental features, which can modify physical activity in this group, are unknown.

Objective

To investigate the association between home environment features and home physical activity in patients with visual impairment.

Design, Setting, and Participants

This cross-sectional study of clinical patients included participants with glaucoma suspect and primary glaucoma who were 60 years or older with varying degrees of visual field damage. Study participants were recruited from the Johns Hopkins Wilmer Eye Institute Glaucoma Clinic, Baltimore, Maryland, from September 2013 through March 2015. Data were analyzed from December 19, 2022, through December 25, 2022.

Main Outcomes and Measures

Total in-home steps taken per day was the primary outcome measure; time in daily home physical activity and nonsedentary activity were secondary outcomes.

Results

A total of 153 participants were included in analyses with mean age of 71 (SD, 7.8) years and 71 were female (46%). Sixty percent had more than 1 comorbid illness, about one-third took 5 or more prescription drugs, and median daily home steps were 1137. Median integrated visual field sensitivity was 28 dB. Better-eye median visual acuity in logMAR was 0.05 (20/22 Snellen equivalent). For every 0.1-log unit increment in average measured home lighting, participants took 5% more daily steps (rate ratio [RR], 1.05; 95% CI, 1.00-1.10; P = .04) and had a 3% faster average daily peak cadence (RR, 1.03; 95% CI, 1.01-1.05; P = .01). The average number of nonsedentary activity minutes (RR, 1.04; 95% CI, 1.00-1.07; P = .06), average bout duration (β = 0.03; 95% CI, 0.00-.07; P = .06), and activity fragmentation (β = -0.06; 95% CI, -0.13 to 0.00; P = .06) showed associations with home lighting. The number of hazards was not associated with any activity metric (steps: RR, 1.14; 95% CI, 0.96-1.34; P = .13; peak cadence: RR, 1.00; 95% CI, 0.93-1.08; P = .98; and nonsedentary time: RR, 1.11; 95% CI, 0.98-1.26; P = .11), nor was the frequency of hazards.

Conclusions and Relevance

In this study, results demonstrated that home environment features, particularly lighting, may influence home activity metrics in older adults with visual impairment. Further prospective studies would be needed to confirm if home modifications can improve at-home activity.

The Influence of Marriage and Cohabitation on Physical Activity Among Middle-Aged and Older People

Using data from a nationally representative longitudinal study, Midlife in the United States (waves 1-3; N = 1113; aged 49-93), this study investigated whether partnered living status (partnered vs. non-partnered) and partnered living quality (support/strain from partner, partner disagreements) were associated with physical activity in middle-aged/older adults. Regressions were performed to test the effect of change or stability in partnered living status across three waves and relationship quality on the frequency of moderate and vigorous physical activity at Wave 3. Subjects who changed from non-partnered to partnered living had the highest moderate and vigorous physical activity levels. Partner support was positively associated with moderate physical activity (β = .50, p < .01), and partner disagreement was negatively associated with vigorous physical activity (β = -.27, p < .01). Results suggest that partnered living status and quality can influence physical activity among the aging population. Physical activity interventions among older adults may benefit from including social support as a key component.

Cross-sectional and longitudinal neural predictors of physical activity and sedentary behaviour from a 6-month randomized controlled trial

A sedentary lifestyle offers immediate gratification, but at the expense of long-term health. It is thus critical to understand how the brain evaluates immediate rewards and long-term health effects in the context of deciding whether to engage in moderate-to-vigorous physical activity (MVPA) or sedentary behaviour (SB). In this secondary analysis of a 6-month randomized controlled trial to increase MVPA and reduce SB among community-dwelling adults, we explored how neural activity during an executive control task was associated with MVPA and SB levels. At baseline, a subset of participants (n = 26/61) underwent task-based functional magnetic resonance imaging (fMRI) to examine neural activity underlying executive control using the Now/Later task. MVPA and SB were measured objectively using the Sensewear Mini at baseline, and 2, 4, and 6 months follow-up. We then examined the associations of baseline neural activation underlying executive control with: (1) baseline MVPA or SB; and (2) changes in MVPA and SB over 6 months. Our results determined that there is a complex neurocognitive system associated with MVPA levels, while SB appears to lack any neurocognitive control. In other words, MVPA appears to require neurocognitive effort, while SB may be the default behavioural pattern in adults.

Developing Patient-Centered Preventative Care to Reduce Mobility Disability With Aging: Preferences From a Discrete Choice Experiment

BACKGROUND AND PURPOSE

Mobility disability is the most prevalent form of disability for older adults in the United States. A physical therapy mobility checkup (MC) under development is a patient-centered preventative physical therapy visit. It includes physical performance testing and education on physical performance as a valuable and modifiable health indicator. The purpose of this study was to identify the proportion of older adults willing to participate in an MC, the age at which they would initiate care, their desired frequency of participation, and the characteristics, or attributes, of the MC they preferred.

METHODS

In a cross-sectional study conducted at the Minnesota State Fair, adults older than 55 years answered survey questions about preventative health practices and completed a discrete choice experiment (DCE) to determine their preferences for the MC. Attributes studied in the DCE were visit duration, checkup content, education, and possible outcomes of participating in preventative care for mobility. Descriptive statistics characterized demographic information and survey responses. Conjoint choice modeling estimated the main effect for each DCE attribute.

RESULTS AND DISCUSSION

One hundred sixty-six older adults participated in the study. Seventy-eight percent indicated that they would choose an MC if available. Most participants (66%) believed that MCs should occur before 60 years of age and at least annually (68%). A 30-minute visit duration, which accounted for 84% of attribute importance, was preferred. Balance, the preferred content of the MC, accounted for 12% of the attribute importance. Preferences for educational content and possible outcomes of participation with preventative care aimed at preventing mobility loss were not statistically significant.

CONCLUSION

Older adults value preventative care for reducing mobility disability. They identified time efficiency and the inclusion of measures to assess balance as priorities for this preventative physical therapy visit.

Anorexia of aging: An international assessment of healthcare providers' knowledge and practice gaps

BACKGROUND

Anorexia of aging is a common geriatric syndrome that includes loss of appetite and/or reduced food intake, with associated undernutrition, unintended weight loss, sarcopenia, functional decline, loss of independence and other adverse health outcomes. Anorexia of aging can have multiple and severe consequences and is often overlooked by healthcare professionals (HCPs). Even more concerningly, clinicians commonly accept anorexia of aging as an inevitable part of 'normal' aging. The aim of this assessment was to identify current gaps in professional knowledge and practice in identifying and managing older persons with anorexia. Results may guide educational programmes to fill the gaps identified and therefore improve patient outcomes.

METHODS

This international assessment was conducted using a mixed-methods approach, including focus group interviews with subject matter experts and an electronic survey of practicing HCPs. The assessment was led by the Society on Sarcopenia, Cachexia and Wasting Disorders (SCWD) and was supported by in-country collaborating organizations.

RESULTS

A quantitative survey of 26 multiple-choice questions was completed by physicians, dietitians and other HCPs (n = 1545). Most HCPs (56.8%) recognize a consistent definition of anorexia of aging as a loss of appetite and/or low food intake. Cognitive changes/dementia (91%) and dysphagia (87%) are seen as the biggest risk factors. Most respondents were confident to give nutritional (62%) and physical activity (59.4%) recommendations and engaged caregivers such as family members in supporting older adults with anorexia (80.6%). Most clinicians assessed appetite at each visit (66.7%), although weight is not measured at every visit (41.5%). Apart from the Mini-Nutritional Assessment Short Form (39%), other tools to screen for appetite loss are not frequently used or no tools are used at all (29.4%). A high number of respondents (38.7%) believe that anorexia is a normal part of aging. Results show that treatment is focused on swallowing disorders (78%), dentition issues (76%) and increasing oral intake (fortified foods [75%] and oral nutritional supplements [74%]). Nevertheless, the lack of high-quality evidence is perceived as a barrier to optimal treatment (49.2%).

CONCLUSIONS

Findings from this international assessment highlight the challenges in the care of older adults with or at risk for anorexia of aging. Identifying professional practice gaps between individual HCPs and team-based gaps can provide a basis for healthcare education that is addressed at root causes, targeted to specific audiences and developed to improve individual and team practices that contribute to improving patient outcomes.

Barriers to and facilitators of a healthy lifestyle for patients with gynecological cancer: a systematic review of qualitative and quantitative research with healthcare providers and patients

The prevalence of an unhealthy lifestyle among patients with gynecological cancer is high and associated with increased risk of all-cause mortality. Although lifestyle changes have the potential to improve outcomes, lifestyle counseling is not routinely integrated into standard care. This review explores research on the barriers to and facilitators of both the promotion of healthy lifestyles by healthcare providers (HCPs) and healthy lifestyle changes by patients with gynecological cancer. The Theoretical Domains Framework (TDF) was used to deductively code the identified factors for a comprehensive understanding of the barriers and facilitators. A search across five databases yielded a total of 12,687 unique studies, of which 43 were included in the review. Of these 43, 39 included gynecological cancer patients and only 6 included HCPs. Among the barriers identified for HCPs, most studies evaluated barriers regarding weight loss counseling. Limited knowledge, reluctance to address weight loss, skepticism about the benefits, and workload concerns were commonly reported barriers for HCPs. HCPs will benefit from education and training in lifestyle counseling, including effective communication skills like motivational interviewing. Gynecological cancer patients lacked tools, support, knowledge, and faced mental health issues, environmental constraints, and physical limitations. The review emphasizes the importance of addressing these barriers and utilizing identified facilitators, such as social support, to promote and support healthy lifestyle behaviors on the part of patients and their promotion by HCPs. Future research should focus not only on patients but also on supporting HCPs and implementing necessary changes in current practices.

Determinants of caregiving grandparents' physical activity and sedentary behavior: a qualitative study using focus group discussions

BACKGROUND

Evidence on the factors influencing physical activity (PA) and sedentary behavior (SB) in middle-aged and older adults taking care of their grandchild(ren) is limited, even though this knowledge seems imperative when considering the unique relationship between grandparents and their grandchild(ren) as well as the rising popularity of intergenerational interventions targeting these energy-expenditure related behaviors. Therefore, this explorative qualitative study aimed to identify the determinants of PA and SB levels among Flemish caregiving grandparents in the presence of their grandchild(ren) aged between 0-5 years.

METHODS

Six online focus group discussions were conducted via Microsoft Teams, all of which were audio- and videotaped with permission granted by the participating grandparents. In total, nine caregiving grandfathers and 28 caregiving grandmothers (overall mean age = 60.9 ± 4.1y) participated in this study. An inductive content analysis approach was used to derive subcategories, categories and themes from the verbatim transcribed data using NVivo R1.

RESULTS

Caregiving grandparents' levels of PA and SB were both influenced by personal determinants (e.g., physical health, grandparental perceptions and responsibilities), interpersonal determinants (e.g., characteristics of the grandchild(ren), such as age-related physical/motor development and family interaction), and environmental determinants (e.g., weather and seasonal circumstances). PA levels of caregiving grandparents were further affected by additional personal determinants (e.g., age of the grandparent, planning and location) and interpersonal determinants (e.g., characteristics of the grandchild(ren), such as new experiences of the grandchild(ren)). Additionally, some personal determinants (e.g., perception of educational value) and interpersonal determinants (e.g., characteristics of the grandchild(ren), such as age-related cognitive development and health of the grandchild(ren)) were strictly mentioned to influence caregiving grandparents' SB.

CONCLUSIONS

Acknowledging the unique relationship between grandparents and their grandchild(ren), the current study identified specific factors determining grandparents' PA and SB levels during the provision of grandchild care. Besides, it turned out of importance to take the interplay between the different determinants into account. Especially, for those grandparents with older grandchild(ren), within the studied 0-5 years age range, more attention should be paid to grandchild characteristics as part of the interpersonal determinants when setting up interventions to improve levels of PA and SB in caregiving grandparents.

The Importance of Activating Factors in Physical Activity Interventions for Older Adults Using Information and Communication Technologies: Systematic Review

Background

In an aging population, it is important to activate older adults in taking care of their own health. Increasing physical activity is one way to avoid or lessen age-related physical and mental impairments. Interest in the use of information and communication technology (ICT) tools to promote physical activity among older adults is growing considerably. Such tools are suitable for communicating activation factors-skills, knowledge, and motivation-by integrating a variety of behavior change techniques (BCTs) to enhance physical activity. Although activation factors have been incorporated into physical activity interventions using ICT, little is known about the actual integration methods used in such interventions or about the effects of activation factors on influencing behavior change.

Objective

The first aim of this study was to identify which of the activation factors were covered in physical activity-promoting ICT interventions for older adults and which BCTs were used to address them. The second objective was to classify the user interaction interfaces and delivery modes that were used to promote these activation factors.

Methods

The search engines of PubMed, Web of Science, and ScienceDirect were used to search for and identify articles examining the effectiveness of ICT interventions for promoting physical activity in older adults. References and related data were selected, extracted, and reviewed independently by 2 reviewers. The risk of bias was assessed, and any conflict was addressed by a third separate reviewer. Selected articles included older adults aged ≥55 years without pre-existing medical diseases and other physical or mental conditions that could hinder movement.

Results

In total, 368 records were retrieved, and 13 studies met all inclusion criteria. Articles differed in terms of themes, timescales, user interaction interfaces, and outcome measures; therefore, a quantitative data synthesis was not feasible. Motivation was the most promoted activation factor among all trials (33 times). An app and a smartwatch were used in the majority of intervention groups (7/20, 35%) for tracking physical activity and receiving personalized feedback based on the individual goals. Skills (25 times) and knowledge (17 times) were the next most commonly addressed activation factors. Face-to-face interaction was the most used approach to targeting users' skills, including providing instructions on how to perform a behavior and exchanging knowledge via education on the health consequences of insufficient physical activity. Overall, integrating all 3 activation factors and using multiple user interaction interfaces with a variety of delivery modes proved the most effective in improving physical activity.

Conclusions

This study highlights commonly used BCTs and preferred modes of their delivery. So far, only a limited number of available BCTs (21/99, 21%) have been integrated. Considering their effectiveness, a larger variety of BCTs that address skills, knowledge, and motivation should be exploited in future ICT interventions.

Self-regulation of effort for a better health-related quality of life: a multidimensional activity pacing model for chronic pain and fatigue management

PURPOSE

To propose a comprehensive multidimensional model of activity pacing that improves health-related quality of life and promotes sustained physical activity engagement among adults with chronic conditions.

MATERIALS AND METHODS

A narrative review was conducted to examine the existing literature on activity pacing, health-related quality of life, pain and fatigue management, and physical activity promotion in chronic conditions.

RESULTS

The literature revealed a lack of a cohesive approach towards a multidimensional model for using activity pacing to improve health-related quality of life. A comprehensive multidimensional model of activity pacing was proposed, emphasizing the importance of considering all aspects of pacing for sustained physical activity engagement and improved health-related quality of life. The model incorporates elements such as rest breaks, self-regulatory skills, environmental factors, and effective coping strategies for depression/anxiety. It takes into account physical, psychological, and environmental factors, all of which contribute significantly to the enhancement of health-related quality of life, physical function, and overall well-being, reflecting a holistic approach.

CONCLUSIONS

The model offers guidance to researchers and clinicians in effectively educating patients on activity pacing acquisition and in developing effective interventions to enhance physical activity engagement and health outcomes among adults with chronic conditions. Additionally, it serves as a tool towards facilitating discussions on sustained physical activity and a healthy lifestyle for patients, which can eventually lead to improved quality of life.

Predictive Strategies to Reduce the Risk of Rehospitalization with a Focus on Frail Older Adults: A Narrative Review

Frailty is a geriatric syndrome that has physical, cognitive, psychological, social, and environmental components and is characterized by a decrease in physiological reserves. Frailty is associated with several adverse health outcomes such as an increase in rehospitalization rates, falls, delirium, incontinence, dependency on daily living activities, morbidity, and mortality. Older adults may become frailer with each hospitalization; thus, it is beneficial to develop and implement preventive strategies. The present review aims to highlight the epidemiological importance of frailty in rehospitalization and to compile predictive strategies and related interventions to prevent hospitalizations. Firstly, it is important to identify pre-frail and frail older adults using an instrument with high validity and reliability, which can be a practically applicable screening tool. Comprehensive geriatric assessment-based care is an important strategy known to reduce morbidity, mortality, and rehospitalization in older adults and aims to meet the needs of frail patients with a multidisciplinary approach and intervention that includes physiological, psychological, and social domains. Moreover, effective multimorbidity management, physical activity, nutritional support, preventing cognitive frailty, avoiding polypharmacy and anticholinergic drug burden, immunization, social support, and reducing the caregiver burden are other recommended predictive strategies to prevent post-discharge rehospitalization in frail older adults.

Unsupervised Cluster Analysis of Walking Activity Data for Healthy Individuals and Individuals with Lower Limb Amputation

This is the first investigation to perform an unsupervised cluster analysis of activities performed by individuals with lower limb amputation (ILLAs) and individuals without gait impairment, in free-living conditions. Eight individuals with no gait impairments and four ILLAs wore a thigh-based accelerometer and walked on an improvised route across a variety of terrains in the vicinity of their homes. Their physical activity data were clustered to extract 'unique' groupings in a low-dimension feature space in an unsupervised learning approach, and an algorithm was created to automatically distinguish such activities. After testing three dimensionality reduction methods-namely, principal component analysis (PCA), t-distributed stochastic neighbor embedding (tSNE), and uniform manifold approximation and projection (UMAP)-we selected tSNE due to its performance and stable outputs. Cluster formation of activities via DBSCAN only occurred after the data were reduced to two dimensions via tSNE and contained only samples for a single individual. Additionally, through analysis of the t-SNE plots, appreciable clusters in walking-based activities were only apparent with ground walking and stair ambulation. Through a combination of density-based clustering and analysis of cluster distance and density, a novel algorithm inspired by the t-SNE plots, resulting in three proposed and validated hypotheses, was able to identify cluster formations that arose from ground walking and stair ambulation. Low dimensional clustering of activities has thus been found feasible when analyzing individual sets of data and can currently recognize stair and ground walking ambulation.

Estimation of Obesity Levels through the Proposed Predictive Approach Based on Physical Activity and Nutritional Habits

Obesity is the excessive accumulation of adipose tissue in the body that leads to health risks. The study aimed to classify obesity levels using a tree-based machine-learning approach considering physical activity and nutritional habits. Methods: The current study employed an observational design, collecting data from a public dataset via a web-based survey to assess eating habits and physical activity levels. The data included gender, age, height, weight, family history of being overweight, dietary patterns, physical activity frequency, and more. Data preprocessing involved addressing class imbalance using Synthetic Minority Over-sampling TEchnique-Nominal Continuous (SMOTE-NC) and feature selection using Recursive Feature Elimination (RFE). Three classification algorithms (logistic regression (LR), random forest (RF), and Extreme Gradient Boosting (XGBoost)) were used for obesity level prediction, and Bayesian optimization was employed for hyperparameter tuning. The performance of different models was evaluated using metrics such as accuracy, recall, precision, F1-score, area under the curve (AUC), and precision-recall curve. The LR model showed the best performance across most metrics, followed by RF and XGBoost. Feature selection improved the performance of LR and RF models, while XGBoost's performance was mixed. The study contributes to the understanding of obesity classification using machine-learning techniques based on physical activity and nutritional habits. The LR model demonstrated the most robust performance, and feature selection was shown to enhance model efficiency. The findings underscore the importance of considering both physical activity and nutritional habits in addressing the obesity epidemic.

Influence of different modes of exercise training on inflammatory markers in older adults with and without chronic diseases: A systematic review and meta-analysis

INTRODUCTION

Ageing can be accompanied by increased inflammation, which contributes to the development of sarcopenia. Exercise training could be effective for preventing sarcopenia and mitigate inflammation and thus a viable intervention in ageing. Therefore, we performed a systematic review and meta-analysis to investigate the effects of exercise training on markers of inflammation including interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and C-reactive protein (CRP) in older adults (≥65 years). Exercise-based interventions are most successful in preventing the decline in skeletal muscle mass and in preserving or ameliorating functional capacities with increasing age.

METHOD

PubMed and Web of Science were searched through to December 2021 using "exercise", "inflammatory markers", "elderly", and "randomized controlled trial" to identify randomized trials evaluating the effects of exercise training versus control groups on IL-6, TNF-α, and CRP in older adults with mean ages ≥ 65 yrs. Standardized mean differences (SMD) and 95% confidence intervals (95% CIs) were determined using random effects models.

RESULTS

Forty studies involving 49 trials and 1,898 older adults were included in the meta-analysis. Overall, exercise training reduced IL-6 [-0.17 (95% CI -0.32 to -0.02), p = 0.02], TNF-α [-0.30 (95% CI -0.46 to -0.13), p = 0.001], and CRP [-0.45 (95% CI -0.61 to -0.29), p = 0.001]. Subgroup analyses showed that IL-6 was reduced significantly by combined training, TNF-α by aerobic training, and CRP by aerobic, resistance, and combined training. In addition, exercise training reduced IL-6 and TNF-α in older adults with chronic diseases, and CRP in older adults with and without chronic diseases.

CONCLUSION

The current results highlight that exercise training, regardless of exercise type, has small to moderate beneficial effects on markers of inflammation in older adults, particularly in those with chronic diseases.

Effects of a Multicomponent Exercise and Therapeutic Lifestyle (CERgAS) Intervention on Gait Function in Lower-Income Urban-Dwelling Older Adults: A Cluster Randomized Controlled Trial

This study aims to determine the effectiveness of a multicomponent exercise and therapeutic lifestyle (CERgAS) intervention at improving gait speed among older people in an urban poor setting in Malaysia. A total of 249 participants were divided into the intervention (n = 163) and control (n = 86) groups. The mean (SD) age of participants was 67.83 (6.37) and consisted of 88 (35.3%) males and 161 (64.7%) females. A generalized estimating equation with an intention-to-treat analysis was used to measure gait speed at four time points, baseline (T0), 6 weeks (T1), 3 months postintervention (T2), and 6 months postintervention (T3). The results showed significant changes for time between T0 and T3 (mean difference = 0.0882, p = .001), whereas no significant association were found for group (p = .650) and interaction (p = .348) effects. A 6-week intervention is inadequate to improve gait speed. Future efforts should introduce physical activity monitoring and increase exercise duration, frequency, and intensity.

Unraveling age-related impairment of the neuromuscular system: exploring biomechanical and neurophysiological perspectives

With extended life expectancy, the quality of life of elders is a priority. Loss of mobility, increased morbidity and risks of falls have dramatic individual and societal impacts. Here we consider the age-related modifications of gait, from a biomechanical and neurophysiological perspective. Among the many factors of frailty involved (e.g., metabolic, hormonal, immunological), loss of muscle strength and neurodegenerative changes inducing slower muscle contraction may play a key role. We highlight that the impact of the multifactorial age-related changes in the neuromuscular systems results in common features of gait in the immature gait of infants and older adults. Besides, we also consider the reversibility of age-related neuromuscular deterioration by, on the one hand, exercise training, and the other hand, novel techniques such as direct spinal stimulation (tsDCS).

Move Your Body, Boost Your Brain: The Positive Impact of Physical Activity on Cognition across All Age Groups

While the physical improvements from exercise have been well documented over the years, the impact of physical activity on mental health has recently become an object of interest. Physical exercise improves cognition, particularly attention, memory, and executive functions. However, the mechanisms underlying these effects have yet to be fully understood. Consequently, we conducted a narrative literature review concerning the association between acute and chronic physical activity and cognition to provide an overview of exercise-induced benefits during the lifetime of a person. Most previous papers mainly reported exercise-related greater expression of neurotransmitter and neurotrophic factors. Recently, structural and functional magnetic resonance imaging techniques allowed for the detection of increased grey matter volumes for specific brain regions and substantial modifications in the default mode, frontoparietal, and dorsal attention networks following exercise. Here, we highlighted that physical activity induced significant changes in functional brain activation and cognitive performance in every age group and could counteract psychological disorders and neural decline. No particular age group gained better benefits from exercise, and a specific exercise type could generate better cognitive improvements for a selected target subject. Further research should develop appropriate intervention programs concerning age and comorbidity to achieve the most significant cognitive outcomes.

A systematic review of physical activity: benefits and needs for maintenance of quality of life among adults with intellectual disability

The inactivity of people with intellectual disabilities (PwID) is a major contributor to ill health. Probably because people with intellectual disabilities are not adequately informed about physical activity and intervention programs required to enhance their fitness. This study critically reviewed physical activity: benefits and needs for maintenance of quality of life among adults with intellectual disability. An extensive search of bibliographic databases such as PubMed, PsycINFO, BioMed Central and Medline identified 735 academic papers. The research rigour was evaluated, and the validity of the findings was established. Based on the inclusion criteria, 15 studies were included in the review. Various forms of physical activity were studied as interventions. The results of a critical review indicate that physical activity has a moderate to strong positive impact on weight loss, sedentary behaviour, and disability-related quality of life. Adults with ID may benefit from physical activity as a non-pharmaceutical method of improving their health needs. However, this study's results may only apply to some adults with intellectual disabilities. The sample size needs to be increased in future studies in order to draw generalizable conclusions.

Associations between Physical Activity and Health-Related Quality of Life among Community-Dwelling Older Adults: A Cross-Sectional Study in Urban Greece

Physical activity is an important factor in achieving healthy aging, offering older persons multiple benefits in terms of maintaining and improving their health and wellbeing. The aim of this study was to investigate the effect of physical activity on the quality of life of older adults. A cross-sectional study was conducted from February to May 2022, using the Short-Form Health Survey (SF-36) and the International Physical Activity Questionnaire (IPAQ). A total of 124 people aged 65 and over participated in the survey. The average age of the participants was 71.6 years, and 62.1% were women. Participants showed a moderate quality of life with regard to the physical health dimension (mean score 52.4) and a higher quality of life with regard to the mental health dimension (mean score 63.1) compared to the expected values of the population. Low levels of physical activity were recorded among older adults, reaching a rate of 83.9%. A moderate or high level of physical activity has been found to contribute to a better physical functioning (p = 0.03), vitality (p = 0.02) and general health (p = 0.01). Finally, comorbidity had a negative impact on physical activity (p = 0.03) and quality of life regarding mental and physical health in older adults. The study showed very low levels of physical activity in older Greek adults. The management of this problem, which was intensified during the COVID-19 pandemic, should be a high priority in public health programs focusing on healthy aging, as physical activity affects and promotes many of the basic aspects of quality of life.

Association between upper limb movements during drumming and cognition in older adults with cognitive impairment and dementia at a nursing home: a pilot study

Background

Despite the association between motor dysfunction and dementia, quantitative assessment of dementia-related specific motor dysfunction in patients with severe dementia is difficult. Thus, this study aimed to develop a new method to measure upper limb motor function in people with dementia.

Methods

We examined the relationship between dementia severity and dementia-related specific motor dysfunction using the Mini-Mental State Examination (MMSE), a dementia screening test. Participants comprised 16 nursing home residents with a mean age of 86 years and MMSE score of 14.56 (range, 1-23) Points. Participants were seated in a circle and instructed to play a drum that was placed in their lap using mallets (drumsticks) in their dominant hand. Acceleration and gyroscopic sensors were attached to their wrists to collect data on arm movements while drumming. Upper limb motor characteristics were confirmed by recording acceleration and arm movement during drumming and analyzing the correlation with handgrip strength.

Results

Handgrip strength was correlated with arm elevation angle during drumming. The arm elevation angle displayed a significant regression equation with the MMSE score and showed the best regression equation along with handgrip strength (adjusted R² = 0.6035, p = 0.0009).

Conclusion

We developed a new method using drums to measure upper limb motor function in people with dementia. We also verified that the average arm elevation angle during drumming could predict cognitive dysfunction. This system may be used to monitor people with dementia in a simple and safe way.

Exercise with a wearable hip-assist robot improved physical function and walking efficiency in older adults

Wearable assistive robotics has emerged as a promising technology to supplement or replace motor functions and to retrain people recovering from an injury or living with reduced mobility. We developed delayed output feedback control for a wearable hip-assistive robot, the EX1, to provide gait assistance. Our purpose in this study was to investigate the effects of long-term exercise with EX1 on gait, physical function, and cardiopulmonary metabolic energy efficiency in elderly people. This study used parallel experimental (exercise with EX1) and control groups (exercise without EX1). A total of 60 community-dwelling elderly persons participated in 18 exercise intervention sessions during 6 weeks, and all participants were assessed at 5 time points: before exercise, after 9 exercise sessions, after 18 sessions, and 1 month and 3 months after the last session. The spatiotemporal gait parameters, kinematics, kinetics, and muscle strength of the trunk and lower extremities improved more after exercise with EX1 than in that without EX1. Furthermore, the effort of muscles over the trunk and lower extremities throughout the total gait cycle (100%) significantly decreased after exercise with EX1. The net metabolic energy costs during walking significantly improved, and functional assessment scores improved more in the experimental group than in the control group. Our findings provide evidence supporting the application of EX1 in physical activity and gait exercise is effective to improve age-related declines in gait, physical function, and cardiopulmonary metabolic efficiency among older adults.

Physical activity and functional disability among older adults in Ghana: The moderating role of multi-morbidity

Knowledge about how physical activity levels relate to functional disability is essential for health promotion and planning older adults' care or rehabilitation. The risk of living with one or more chronic health conditions increases with increasing age in lower and higher income countries-many of which are associated with physical inactivity. We conducted a cross-sectional study to examine the moderating role of multimorbidity on physical activity and its measures on functional disability among older adults in Ghana. Data from WHO's Study on global AGEing and adult health Ghana Wave 2 with a sample of 4,446 people aged 50+ years was used for this study. Functional disability was assessed using the 12-item WHO Disability Assessment Schedule 2.0. Three categories of physical activity levels were used: vigorous intensity, moderate intensity, and walking. Past month diagnosis by a doctor was used to assess the presence of a chronic condition, and the presence of two or more conditions was used to define multi-morbidity. Logistic regressions with a post hoc interactional tests were used to examine the associations. Overall, physical activity had a significant association with functional disability (OR = 0.25, 95%CI; 0.12, 0.32). A similar relationship was found for vigorous-intensity (OR = 0.19, 95%CI: 0.12, 0.29), moderate-intensity (OR = 0.19, 95%CI: 0.15, 0.25) and walking (OR = 0.41, 95%CI: 0.33, 0.51). Older adults living with one condition and physically active were 47% less likely to experience functional disability compared with the less active counterparts living with at least two chronic conditions. Among the three measures of physical activity, multimorbidity moderated the relationship between walking and functional disability. Future strategies for meeting the health and long-term care needs of older adults, particularly those living with only one chronic condition in Ghana should consider encouraging walking. Policies, financial assistance, family, and community level interventions aimed to promote and sustain physical activity among older adults should be a priority for stakeholders in Ghana.

The benefits of regular aerobic exercise training on cerebrovascular function and cognition in older adults

We compared the differences in cerebrovascular and cognitive function between 13 aerobic exercise trained, older adults and 13 age-, height- and sex-matched sedentary, untrained controls. We determined whether other measures accounted for differences in cerebrovascular and cognitive function between these groups and examined the associations between these functions. Participants undertook anthropometric, mood, cardiovascular, exercise performance, strength, cerebrovascular, and cognitive measurements, and a blood collection. Transcranial Doppler ultrasonography determined cerebrovascular responsiveness (CVR) to hypercapnia and cognitive stimuli. The trained group had a higher CVR to hypercapnia (80.3 ± 7.2 vs 35.1 ± 6.7%, P < 0.001), CVR to cognitive stimuli (30.1 ± 2.9 vs 17.8 ± 1.4%, P = 0.001) and total composite cognitive score (117 ± 2 vs 98 ± 4, P < 0.001) than the controls. These parameters no longer remained statistically different between the groups following adjustments for covariates. There were positive correlations between the total composite cognitive score and CVR to hypercapnia (r = 0.474, P = 0.014) and CVR to cognitive stimuli (r = 0.685, P < 0.001). We observed a relationship between cerebrovascular and cognitive function in older adults and an interaction between regular lifelong aerobic exercise training and cardiometabolic factors that may directly influence these functions.

Designing Mobile Health Applications to Support Walking for Older Adults

Physical activity is extremely important at an older age and has major benefits. There is a range of applications that help maintain physical activity. However, their adoption among older adults is still limited. The purpose of the study is to explore the key aspects of the design of mobile applications that support walking for older adults. We conducted a field study with older adults, aged 69-79 years, using a technology probe (a mobile application developed as an early prototype) with the purpose of eliciting requirements for mobile health applications. We interviewed the participants during and after the study period, asking them about their motivation for walking, usage of the application, and overall preferences when using such technologies. The findings suggest that mobile applications that support walking should address a range of walking variables, support a long-term learning process, and enable the user to take control and responsibility for the walk. In addition, we provide design guidelines concerning the motivation for walking and the data visualization that would make technology adoption easier. The findings from this study can be used to inform the design of more usable products for older users.

Motivation to Join and Adhere to SilverSneakers Among Older Adults

The purpose of this exploratory study was to determine the reasons why older adults begin attending SilverSneakers exercise program and why they continue to participate. Participants completed a survey (104 complete surveys). Initial attendance was mainly due to SilverSneakers being a health insurance benefit or hearing from a friend, with a lower percentage hearing from a health care provider. Factors that encouraged ongoing attendance included the level of programming, liking the instructor, and working out with peers. Statistically significant relationships were found between long-term adherence and a desire to promote fitness (p = .024) and social aspects of SilverSneakers (p < .01). These insights can be of value when planning outreach to older adults, as well as to promote retention, with physical activity programming.

Effect of sport on health in people aged 60 years and older: a systematic review with meta-analysis

OBJECTIVES

To summarise evidence of benefits of sport for health among people aged 60+.

DESIGN

Systematic review with meta-analysis of randomised controlled trials (RCTs).

DATA SOURCES

Medline, CINAHL, SPORTDiscus, the Physiotherapy Evidence Database from inception to April 2021.

STUDY SELECTION

RCTs investigating the effect of sport on health-related outcomes in people aged 60+ compared with non-active control.

DATA SYNTHESIS AND ANALYSIS

Pooled effect sizes were calculated using random-effect models. Standardised mean differences (SMD), and mean difference (MD) were calculated. The Grading of Recommendations Assessment, Development and Evaluation system was used to assess the certainty of the evidence for analyses with ≥3 studies.

RESULTS

Nine trials (628 participants) reported in 15 articles were included. Participation in sport improved cardiorespiratory fitness (n=5 trials; SMD=0.43, 95% CI 0.17 to 0.70; low certainty evidence), physical function (n=4; SMD=0.62, 95% CI 0.05 to 1.18; very low certainty evidence), and mental health (n=2; SMD=0.28, 95% CI 0.06 to 0.51) and reduced fat mass (n=6; MD=-0.99 kg, 95% CI -1.75kg to -0.23 kg; low certainty evidence) among older people. We found no significant effects of sport on overall physical activity participation, strength, balance, lean mass and bone mineral density (BMD). One study investigating quality of life reported a positive, but non-significant effect of sport.

CONCLUSION

Sport may have a positive impact on health outcomes in people aged 60+. There was uncertainty on the effect of sport on strength, balance, lean mass and BMD. Further research is needed to investigate the optimal type and dose of sport to maximise the long-term benefits among older people.

Adding Mobile Elements to Online Physical Activity Interventions for Adults Aged Over 50 Years: Prototype Development Study

BACKGROUND

Only a minority of adults aged over 50 years meet physical activity (PA) guidelines of the World Health Organization (WHO). eHealth interventions are proven effective tools to help this population increase its PA levels in the short term, among which the Active Plus and I Move interventions have been developed by our own research group. To achieve long-term effects, increase intervention use, and decrease dropout rates, 3 emergent but different mobile elements (an activity tracker, an ecological momentary intervention [EMI] program, and a chatbot) were added separately to Active Plus and I Move. In this study, the prototype development and pilot-testing of these interventions is described.

OBJECTIVE

This study aims to enhance 2 existing PA-stimulating computer-based interventions with 3 mobile elements (an activity tracker, an EMI program, or a chatbot) and test the prototypes on usability and appreciation within a target population of adults aged over 50 years.

METHODS

A systematic design protocol consisting of development, evaluation, and adaptation procedures was followed with involvement of the target population. Literature searches separated per mobile element and interviews with the target population (N=11) led to 6 prototypes: Active Plus or I Move including (1) an activity tracker, (2) EMI, or (3) a chatbot. These prototypes were tested on usability and appreciation during pilot tests (N=47) and subsequently fine-tuned based on the results.

RESULTS

The literature searches and interviews provided important recommendations on the preferences of the target population, which enabled us to develop prototypes. The subsequent pilot tests showed that the mobile elements scored moderate to good on usability, with average System Usability Scale (SUS) scores of 52.2-82.2, and moderate to good on enjoyment and satisfaction, with average scores ranging from 5.1 to 8.1 on a scale of 1-10. The activity tracker received the best scores, followed by EMI, followed by the chatbot. Based on the findings, the activity tracker interventions were fine-tuned and technical difficulties regarding EMI and the chatbot were solved, which is expected to further improve usability and appreciation.

CONCLUSIONS

During this study, 6 prototypes of online PA interventions with added mobile elements were developed and tested for usability and appreciation. Although all prototypes scored moderate to high on usability, enjoyment, and satisfaction, it can be concluded that the integration of an activity tracker with a computer-based PA intervention is the most promising option among the 3 mobile elements tested during this study. The prototype development steps of the systematic design protocol followed can be considered useful and successful for the purposes of this study. The interventions can now be evaluated on a larger scale through a randomized controlled trial.

Urbanization and physical activity in the global Prospective Urban and Rural Epidemiology study

Urbanization may influence physical activity (PA) levels, although little evidence is available for low- and middle- income countries where urbanization is occurring fastest. We evaluated associations between urbanization and total PA, as well as work-, leisure-, home-, and transport-specific PA, for 138,206 adults living in 698 communities across 22 countries within the Prospective Urban and Rural Epidemiology (PURE) study. The 1-week long-form International PA Questionnaire was administered at baseline (2003-2015). We used satellite-derived population density and impervious surface area estimates to quantify baseline urbanization levels for study communities, as well as change measures for 5- and 10-years prior to PA surveys. We used generalized linear mixed effects models to examine associations between urbanization measures and PA levels, controlling for individual, household and community factors. Higher community baseline levels of population density (- 12.4% per IQR, 95% CI - 16.0, - 8.7) and impervious surface area (- 29.2% per IQR, 95% CI - 37.5, - 19.7), as well as the rate of change in 5-year population density (- 17.2% per IQR, 95% CI - 25.7, - 7.7), were associated with lower total PA levels. Important differences in the associations between urbanization and PA were observed between PA domains, country-income levels, urban/rural status, and sex. These findings provide new information on the complex associations between urbanization and PA.

Impacts of Social Isolation on the Physical and Mental Health of Older Adults During Quarantine: A Systematic Review

OBJECTIVES

To systematically review articles that reported the impacts of social isolation on the physical and mental health of healthy older adults during the coronavirus disease 2019 (Covid-19) quarantine.

METHODS

Electronic search was performed in PubMed, EMBASE, Web of Science, Scopus, and BIREME databases. It included cohort and cross-sectional studies published between January 2020 and January 2022 which evaluated the impacts of social isolation on the physical and mental health of older adults during quarantine. The study was registered in PROSPERO (CRD42021269720).

RESULTS

Out of 8,505 studies identified, 17 met the inclusion criteria, with moderate to excellent quality. The majority of the older population perceived changes in their physical and mental health. Impacts differed in cohorts according to sex, age group, income, social participation, exercising before and during confinement, and living alone or with other people.

CONCLUSIONS

The long period of social isolation dictated by the COVID-19 pandemic caused changes in most older adults`, reducing levels of physical activity and/or generating depression, anxiety, fear, and mood problems. Follow-up studies are necessary to observe the evolution of these impacts.

CLINICAL IMPLICATIONS

Public policies must be developed to promote the emotional and physical health of the older adult population in the post-pandemic period.

User experiences of older adults navigating an online database of community-based physical activity programs

Objectives

This study aimed to (1) explore older adult user experiences navigating an online health database of local physical activity programs; (2) compare navigational feedback with age-friendly website design guidelines; (3) assess online database completeness.

Methods

Focus groups, including guided tasks and a semi-structured interview script, gathered navigational user experiences of fifteen older adults. A review of the literature sought age-friendly best practice website design guidelines and a website search for local physical activity programs was completed.

Results

The design of the online database website was challenging for older adult participants to navigate and was not ‘intuitive’. Based on focus group feedback, there were multiple discrepancies between the evaluated online database and the established guidelines for designing age-friendly websites. A total of 187 physical activity programs were missing from the database.

Conclusions

Findings provide novel insight into user experiences of older adults navigating online health and physical activity program sites. Redesigning the following age-friendly website recommendations would empower older adults in the use of online databases and promote awareness of local physical activity programs. Health care providers need reliable and age-friendly online resources to link their patients with local physical activity programs to promote healthy aging.

A narrative exploratory study on the perspectives about physical exercise practise in a sample of Portuguese elderly

The overall prevalence of inactivity among individuals aged 55 or older in Portugal is the highest in Europe therefore it's important to develop effective strategies to increase adherence to structured exercise programs by older adults (Picorelli et al., 2014a). The purpose of this paper is to characterise different perspectives on barriers and facilitators to the practise of physical exercise in a sample of the Portuguese elderly. Two groups of enrolled and non-enrolled in a community exercise program were recruited. Each group had 6 participants that were included in the study if they were ≥ 60 years of age. Two focus groups were conducted via Zoom and lasted ≤ 60 min. Participants were asked about five domains regarding physical exercise. Data analysis occurred in three phases by 2 trained and experienced examiners. While the enrolled group highlighted benefits (n = 6) and facilitators (n = 6), and shared strategies to overcome some barriers (n = 2) the non-enrolled group focused on the barriers (n = 6) instead and shared more excuses to justify their non-practice of physical exercise (n = 3). To overcome the barriers considered by the participants in the non-enrolled group, some education strategies focused on physical literacy might be crucial. The high number of barriers felt by the less active older people makes it more complicated for them to adopt and maintain an exercise program. Narratives-based methodologies are interesting methodologies to collect patient-centred perspectives about exercise practise and therefore design adequate programs.

A 'health message' on sustainable physical and mental health for the prolonged COVID-19 and other pandemics

The world has been living with another pandemic physical inactivity (PI) and sedentary behavior (SB) and of other nature for years. As social measures to prevent the spread of COVID-19 have been strengthened, the physical activity (PA) barrier has been hit and the PI/SB pandemic has been exacerbated, and in the current situation, triggered by its prolonged period, it is emerging as a problem to be considered in order to combat the PI/SB pandemic through PA and to maintain continuous physical and mental health. This review aims to summarize existing and recent studies on the effects of PA/SB on physical and mental health in preparation for the context of prolonged COVID-19 and provides an easy and fun way to motivate, access PA, and PA recommendations for maintaining physical and mental health. We performed search strategies on PubMed, Medline, Scopus, and Google Scholar databases, and used a literature review of the current available literature on the COVID-19 and the effects of PI, SB, and PA on physical and mental health. The clinical relevance of this review shows that integrating PA into daily life and reducing prolonged sitting time is an important strategy for continuing a healthy life physically and mentally. As a result, for those who have not yet incorporated exercise as part of their daily routine, fun and easy access to PA suggests that in the long run, may be an opportunity to implement newer habits. In addition, in an emergency such as the COVID-19 quarantine period or other pandemics, it is essential for one to maintain health through PA at home, and underscore the 'health message' of the current review that reducing SB, progressively increasing PA, and doing more PA regularly in the current context prolonged COVID-19 can bring significant benefits to long-term habits and physical and mental health.

Assessing the Effects of Dietary Protein Supplementation on Sarcopenia in Community-Dwelling Older Adults

Sarcopenia, an age-associated skeletal muscle disorder characterized by muscle loss, is associated with disability in elderly populations. This literature review summarizes the impact of protein intake and supplementation on the indicators of severe sarcopenia-muscle mass, muscle strength, and physical function in community-dwelling older adults. We performed a literature search on PubMed, EMBASE, and MedLine, and included studies that evaluated the effects of protein intake with or without exercise intervention and on sarcopenia in community-dwelling older adults. Information regarding study participants, protein intervention, and sarcopenia-related outcomes were collected. Protein supplementation with or without exercise positively improves muscle mass, and aspects of muscle strength and physical function in sarcopenic and pre-frail older adults, while it elicited inconclusive effects in healthy populations. Greater dietary animal-based and soy-based protein diets can improve muscle mass in older adults. In conclusion, protein supplementation can improve muscle mass and reduce the risk of sarcopenia in sarcopenia and pre-frail older adults, while future studies should continue to investigate the effects of protein supplementation on indicators of sarcopenia in healthy older adults.

Basic mobility, accidental falls, and lifetime physical activity among rural and urban community-dwelling older adults: a population-based study in Northern Iceland

The objective of this research was to investigate late-life physical functioning and lifetime history of physical activity (PA) among older adults in rural and urban Arctic communities. Data was collected in a cross-sectional, population-based study among 65 to 92-year-old community-dwelling Icelanders (N = 175, 41% ≥75-year-old, 43% women, 40% rural). Late-life physical functioning was operationalised as: basic mobility (Timed Up and Go in seconds, TUG); fall risk (TUG≥12 sec); a fall (≥1 fall/year); and recurrent falls (≥2 falls/year). PA history was based on a self-assessment. Compared to urban participants, rural participants were more likely to have fallen recently, be at fall risk, and describe more PA history. Among urban participants, no fall in the past year was independently associated with more PA in middle adulthood; and worse basic mobility and late-life fall risk were independently associated with being in the ≥75-year-old group. Among rural participants, recurrent falls were independently associated with being a man; and better basic mobility was independently associated with more PA in late adulthood. To conclude, this evidence supports an important association between better late-life physical functioning and more mid- and late-life PA and encourages further research to understand high fall risk among older men in Arctic rural areas.

The Effects of Multi-Domain Interventions on Cognition: A Systematic Review

This review aimed to evaluate the effects of multi-domain interventions on cognition among individuals without dementia. Multi-domain interventions refer to those combining any single preventive measure such as physical activity, cognitive training, and/or nutrition to prevent dementia. Seventeen studies were included (n = 10,056 total participants; mean age = 73 years), eight of which were rated as strong in quality while the other nine showed moderate quality. The standardized mean difference (SMD; d) was used to calculate the effect size for each included study. Multi-domain interventions consisting of physical activity, cognitive training, cardioprotective nutrition, and/or cardiovascular health education exerted beneficial effects on global cognition, episodic memory, and/or executive function with very small to moderate effect sizes (0.16-0.77). Nurses may consider combining these components to potentially stave off dementia. Future research is warranted to identify the optimal multi-domain intervention components that can induce clinically significant beneficial effects on cognition.

Sundararajan E, Asadi S, Nilashi M, Ab Aziz MJ, Saravanan MS, Abdelhaq M, Alsaqour R. A Hybrid MCDM Approach Based on Fuzzy-Logic and DEMATEL to Evaluate Adult Obesity

Obesity and its complications is one of the main issues in today's world and is increasing rapidly. A wide range of non-contagious diseases, for instance, diabetes type 2, cardiovascular, high blood pressure and stroke, numerous types of cancer, and mental health issues are formed following obesity. According to the WHO, Malaysia is the sixth Asian country with an adult population suffering from obesity. Therefore, identifying risk factors associated with obesity among Malaysian adults is necessary. For this purpose, this study strives to investigate and assess the risk factors related to obesity and overweight in this country. A quantitative approach was employed by surveying 26 healthcare professionals by questionnaire. Collected data were analyzed with the DEMATEL and Fuzzy Rule-Based methods. We found that lack of physical activity, insufficient sleep, unhealthy diet, genetics, and perceived stress were the most significant risk factors for obesity.

Baduanjin exercise for balance function in community-dwelling older adults with cognitive frailty: a randomized controlled trial protocol

BACKGROUND

Balance function provides a physiological link between the physical and cognitive function, and is a potential predictor for cognitive frailty. As a gentle mind-body exercise, Baduanjin can develop flexibility and co-ordination, thus would be is helpful for the improvement of balance function. This trial will evaluate the effect of Baduanjin on balance function in older adults with CF.

METHODS/DESIGN

A total of 72 community-dwelling older adults with CF will be recruited and randomly allocated (1:1) into the Baduanjin exercise group or usual physical activity control group. All participants will undergo a health education program on nutrition and diet-related knowledge for 6 sessions (30 min per session) during the intervention period. Moreover, participants in the Baduanjin exercise group will receive a 24-week Baduanjin training course of 60 min per session and 3 sessions per week, while those in the usual physical activity control group will be required to maintain their original physical activity. Primary and secondary outcomes will be measured at baseline and after the 24-week intervention period. A mixed linear model will be constructed to analyse the intervention effects.

DISCUSSION

This protocol presents an objective design of a randomized, single-blind trial that will evaluate the effectiveness and safety of traditional Chinese mind-body exercise Baduanjin training on the balance ability of community-dwelling older adults with cognitive frailty. If the results are as expected, this trial will provide evidence of the effect of Baduanjin exercise on balance in an older community-based population.

TRIAL REGISTRATION

This trial was registered in the Chinese Clinical Trial Registry with code ChiCTR2100050857 and was approved on 5 September 2021.
