Does an active lifestyle matter? A longitudinal study of physical activity and health-related determinants in older adults

Self-reported physical activity differentiates vestibular migraine from persistent postural perceptual dizziness

BackgroundIndividuals with dizziness often face balance issues and anxiety, which can result in reduced physical activity levels and decreased participation in their daily activities. Few studies have evaluated physical activity levels in individuals with chronic dizziness, and none have specifically focused on the two most prevalent types: vestibular migraine (VM) and persistent postural perceptual dizziness (PPPD).ObjectiveEvaluate self-reported physical activity levels in individuals diagnosed with PPPD and VM who are awaiting vestibular rehabilitation.MethodsIn a retrospective cross-sectional study, we extracted data from the electronic healthcare records involving 121 individuals presenting either VM or PPPD, referred for vestibular rehabilitation at National Hospital for Neurology and Neurosurgery, University College London. Data on IPAQ (International Physical Activity Questionnaire) and DHI (dizziness handicap inventory) questionnaires were analysed across groups.ResultsThe total sample consisted of 94 (77.7%) women and 27 (22.3%) men with a median age of 56 years old, ranging from 17 to 81 years (P25 = 41 and P75 = 64). Regarding the total sample, a minority (9.1%) of the individuals scored a high activity level on the IPAQ. We observed a significant difference between VM and PPPD in IPAQ score distribution (p = 0.039, Mann-Whitney). Within the category of high physical activity, a larger proportion of individuals had VM compared to PPPD. An inverse correlation was found between DHI and IPAQ (the lower IPAQ, the higher DHI) in the PPPD group (p<0.003).ConclusionsIn a sample of individuals with PPPD and VM referred for vestibular rehabilitation, only a minority demonstrated high physical activity levels on the IPAQ, with PPPD exhibiting lower activity levels compared to those with VM.

Correlation Between Lifestyle Patterns and Cognitive Function Among Community-Dwelling Older Chinese Adults in the Pre-Dementia Stages: A Latent Class Analysis

Lifestyle activity engagement is a modifiable factor for cognitive decline. We aimed to identify lifestyle patterns (LPs) among community-dwelling older adults in the pre-dementia stages and to explore the links between LPs, cognitive function, and individual characteristics. 702 older Chinese adults were recruited. Three LPs were identified by latent class analysis: active aging lifestyle pattern (AALP), leisure lifestyle pattern (LLP), and work-centered lifestyle pattern (WLP). AALP refers to participation in various activities that are meaningful to individuals and benefit their well-being. LLP is the pattern of activities aimed at recreation. WLP refers to the LP where individuals are most likely to engage in work-related activities. However, only AALP is protected against mild cognitive impairment (MCI). Multinomial logistic regression models revealed the differences in individual characteristics among participants with different LPs, indicating the importance of tailored intervention strategies. As a protective factor against MCI, AALP should be highlighted in community-based care.

Understanding the barriers and facilitators of urban greenway use among older and disadvantaged adults: A mixed-methods study in Québec city

Urban greenways are multipurpose and multi-user trails that provide a range of socio-ecological and health benefits, including active transportation, social interactions, and increased well-being. However, despite their numerous benefits, barriers exist that limit urban greenway access and use, particularly among older and disadvantaged adults. This study addresses a significant research gap by examining the nuanced factors that influence the choices and experiences of these specific user groups in Québec City, Canada. We use a mixed-methods' approach to explore the facilitators of and barriers to access and use of two urban greenway trails among older and disadvantaged adults. Our methods included a greenway user count, 96 observation time slots, and 15 semi-structured user interviews. The results revealed significant use of greenway trails by older adults for afternoon walks in both seasons studied (autumn and winter). We also observed variations in use patterns, such as higher levels of solitary walking, reduced levels of winter cycling, and the impracticality of the secondary greenway trail owing to snow conditions. In addition, the findings revealed a wide range of factors that influence greenway access and use, categorized as individual or personal, physical or built environment, social environment, and meteorological or climatic dimensions. Future research can build on these insights to design and assess interventions that capitalize on the facilitators and address any barriers, enhancing the value of urban greenways for older and disadvantaged adults.

Acceptance of a mobile telepresence robot used to teach adapted physical activity to isolated older adults: extending and testing the technology acceptance model

This study aimed to investigate the acceptance of adapted physical activity (APA) by teachers and students before the use of a mobile telepresence robot (MTR), used to remotely supervise isolated older adults' physical activity. While previous studies have shown MTR to be fairly well accepted by older adults, nothing is known about its acceptance by APA teachers themselves. However, if they did not accept it, the MTR would not be used in the end. This would be a public health issue because isolated older adults would not benefit from supervised APA, yet beneficial to their health. To this end, 334 participants answered a survey that measured different psychological variables, based on the technology acceptance model (TAM). Student's t-tests and structural equation modeling were used for data processing. Results showed that, before use, there was not any significant difference between teachers' and students' acceptance of the MTR. Then, perceived usefulness for teaching APA, perceived ease of use, perceived enjoyment, and intention to use the MTR were lower than the mean of the scale, while perceived usefulness for older adults was higher than the mean of the scale. Finally, this study has validated an extended version of the TAM (including the need for competence and MTR self-efficacy), which allowed it to explain 84.3% of the variance of the students' and APA teachers' intention to use the MTR for teaching APA to isolated older adults. Initial obstacles to the use of the MTR seem to exist on the part of APA teachers, prior to their first use, whereas this is not the case for older adults. APA teachers' acceptance should therefore be investigated in future studies to examine whether this trend is confirmed after the effective use of the MTR.

Prevalence, medication adherence, and determinants of type 2 diabetes mellitus during Coronavirus Disease 2019 pandemic among adults in Tanzania

Introduction

Excessive consumption of comfort foods, which are mostly high in carbs, and limitations on outdoor and gym-based physical activities, for instance, are associated with foods high in the glycemic index and raise the risk of obesity and type 2 diabetes. In pandemic and or epidemic situations, peoples' lifestyles may change significantly to lead them to non-communicable diseases. However, lifestyle changes and the occurrence of type 2 diabetes mellitus during the Coronavirus Disease 2019 pandemic among adults have not been well established in Tanzania. This study assessed the prevalence, medication adherence, and determinants of type 2 diabetes mellitus among adults in the country.

Methods

A community-based analytical cross-sectional study was conducted in Dodoma region, Tanzania between September and October 2020 of which 107 adults aged above 18 years were studied regardless of whether they were newly diagnosed with type 2 diabetes mellitus or not using a quantitative research approach. Interviewer-administered lifestyle habits and medication adherence structured questionnaires benchmarked from previous studies served as the main tools of data collection. The statistical package for social sciences computer program was used to analyze the data descriptively for frequencies and percentages and by regression analysis model to determine the association between variables with a 95% confidence interval and 5% significance level.

Results

With a mean age of 31 ± 2.527 years, 59.8% of the respondents were female. 60.7% and 11.7% of the respondents had unhealthy and moderate lifestyle choices respectively. The prevalence of type 2 diabetes mellitus accounted for 63.9% of the respondents of which 44.6% were diagnostically confirmed during the Coronavirus Disease 2019 pandemic against 19.3% of respondents who were diagnosed before the pandemic. Medication adherence among the type 2 diabetes mellitus respondents accounted for 77.9% of the study respondents. Type 2 diabetes mellitus was significantly associated with being in the 36-55 age group (AOR = 1.054; 95% CI: 0.292, 3.162; p < 0.05); being female (AOR = 1.398; 95% CI: 0.205, 3.048; p < 0.05); having a job (AOR = 2.597; 95% CI: 1.243, 4.402, p < 0.05); and having unhealthy lifestyle habits (AOR = 3.301; 95% CI: 1.199, 6.52; p < 0.05).

Conclusion

The majority of adults had type 2 diabetes mellitus of which most of them were confirmed to have the disease during the Coronavirus Disease 2019 pandemic. Few type 2 diabetes mellitus adults did not adhere to their medications as recommended. Their sociodemographic characteristics profiles and unhealthy lifestyles significantly led them to have the problem. The treatment of the disease above and health promotion activities may need to take unhealthy lifestyle choices and certain sociodemographic profiles of adults into consideration to assist in preventing the problem.

Sarcopenia parameters in active older adults - an eight-year longitudinal study

BACKGROUD

Sarcopenia is a common skeletal muscle syndrome that is common in older adults but can be mitigated by adequate and regular physical activity. The development and severity of sarcopenia is favored by several factors, the most influential of which are a sedentary lifestyle and physical inactivity. The aim of this observational longitudinal cohort study was to evaluate changes in sarcopenia parameters, based on the EWGSOP2 definition in a population of active older adults after eight years. It was hypothesized that selected active older adults would perform better on sarcopenia tests than the average population.

METHODS

The 52 active older adults (22 men and 30 women, mean age: 68.4 ± 5.6 years at the time of their first evaluation) participated in the study at two time points eight-years apart. Three sarcopenia parameters were assessed at both time points: Muscle strength (handgrip test), skeletal muscle mass index, and physical performance (gait speed), these parameters were used to diagnose sarcop0enia according to the EWGSOP2 definition. Additional motor tests were also performed at follow-up measurements to assess participants' overall fitness. Participants self-reported physical activity and sedentary behavior using General Physical Activity Questionnaire at baseline and at follow-up measurements.

RESULTS

In the first measurements we did not detect signs of sarcopenia in any individual, but after 8 years, we detected signs of sarcopenia in 7 participants. After eight years, we detected decline in ; muscle strength (-10.2%; p < .001), muscle mass index (-5.4%; p < .001), and physical performance measured with gait speed (-28.6%; p < .001). Similarly, self-reported physical activity and sedentary behavior declined, too (-25.0%; p = .030 and - 48.5%; p < .001, respectively).

CONCLUSIONS

Despite expected lower scores on tests of sarcopenia parameters due to age-related decline, participants performed better on motor tests than reported in similar studies. Nevertheless, the prevalence of sarcopenia was consistent with most of the published literature.

TRIAL REGISTRATION

The clinical trial protocol was registered on ClinicalTrials.gov, identifier: NCT04899531.

Promoting Physical Activity and Health in the Workplace: A Qualitative Study among University Workers, Spain

The social changes we have been experiencing in recent years are generating anxiety that, together with sedentary lifestyles and poor health habits, are leading to premature ageing of society, in addition to the high rates of obesity and associated morbidity. In order to improve the lifestyles of the university community, the objective of this research project was the implementation of the UAL Activa programme based on physical activity. The beneficiaries were UAL staff from different sections, a total of 68 participants aged between 28 and 61 years (Mage = 49.36). Additionally, a total of 12 final year students of the degree in physical activity and sport sciences were responsible for designing and developing the exercise tasks. In-depth interviews were held with the participants of this project about the different benefits that their participation had brought them. The results obtained from the analysis with Nvivo v.10. showed five thematic blocks on the perceived improvements in physical fitness, physical condition, mood and emotional state, assessment of the new lifestyle, and social relations. In conclusion, the benefits of physical activity and the need to continue implementing action and intervention plans to encourage and promote its practice in all sectors of the population were highlighted.

Sarcopenia, obesity, and their association with selected behavioral factors in active older adults

Introduction: The number of obese people in the world is increasing, as is the number of sarcopenic people among the older adults. Although both states are concerning, they can be positively influenced by selected behavioral factors such as adequate nutrition and physical activity. We were interested in the prevalence of sarcopenic obesity in active older people and the influence of behavioral factors on this phenomenon. Methods: The study included 38 older adults (21 women) with a mean age of 75.3 ± 5.0 years. Sarcopenic parameters were determined with different tests: Handgrip Test, Chair Stand Test, Gait Speed, Timed Up and Go Test, and Short Physical Performance Battery. Body composition was measured by dual-energy x-ray absorptiometry. Physical activity level was measured using accelerometers, and nutritional status was assessed using the Mini-Nutritional Assessment and MEDLIFE Index questionnaire. Results: Of all included active participants (the average number of steps per day was 8,916 ± 3,543), 47.4% of them were obese. Of all included women, 52.4% were obese. Sarcopenic obesity was found in three (7.9%) participants. Nutritional status correlated with strength of lower extremities and physical performance tests (gait speed, Timed Up and Go Test and Short Physical performance battery). Higher number of steps per day positively correlates with physical performance. Discussion: Interestingly, we did not find any correlation between the main obesity parameter such as percent body fat or body mass index (and thus sarcopenic obesity) and any of the selected behavioral factors (physical activity, sedentary behavior, or dietary habits). In conclusion, reaching the recommended levels of physical activity in older adults may not be sufficient to prevent the occurrence of obesity and sarcopenic obesity.

Insight into the Molecular Signature of Skeletal Muscle Characterizing Lifelong Football Players

BACKGROUND

Aging and sedentary behavior are independent risk factors for non-communicable diseases. An active lifestyle and structured physical activity are positively associated with a healthier quality of life in the elderly. Here, we explored the proteomic/metabolomic muscular signature induced by lifelong football training associated with successful aging.

METHODS

The study was performed on nine lifelong football players (67.3 ± 2.8 yrs) and nine aged-matched untrained subjects. We performed a proteomic/metabolomic approach on V. lateralis muscle biopsies; the obtained data were analyzed by means of different bioinformatic tools.

RESULTS

Our results indicated that lifelong football training is able to enhance the muscles' oxidative capacity in the elderly by promoting fatty acids as preferential energetic substrates and hence determining a healthier body composition and metabolic profile; furthermore, we showed that the total polyamine content is higher in lifelong football players' muscle, enforcing the involvement of polyamines in muscle growth and hypertrophy.

CONCLUSIONS

Lifelong football training, as a structured physical activity, significantly influences the expression of the proteins and metabolites involved in oxidative metabolism and muscle hypertrophy associated with successful aging.
