Older adults' construal of sedentary behaviour: Implications for reducing sedentary behaviour in older adult populations

Embodied navigation: the influence of lived experience on physical activity and sedentary behavior among older adults

PURPOSE

The impact of a sedentary lifestyle on health and well-being is well recognized. However, there is limited understanding of how a lifetime of physical activity and sedentary behaviour influences an active lifestyle in older adults. The aim of this study was to describe how lived experience of physical activity and sedentary behaviour impacts daily activities among older adults, from a life course perspective.

METHODS

Qualitative content analysis was used; individual telephone interviews were conducted with fourteen older adults aged 71 to 92 years. The participants received initial support from community care and lived in ordinary housing in southern Sweden.

RESULTS

The interviews yielded one theme, "Navigating with an embodied activity compass," and two sub-themes: "Being guided by the past" and "Unveiling pathways through body awareness."

CONCLUSIONS

Our study highlights how older adults' lived experiences of physical activity, with their connections to body awareness and acceptance, impact daily physical activity. These findings offer new knowledge for clinical practitioners balancing recommendations of sedentary behaviour and physical activity, to promote healthy daily physical activity among older adults. Future research and policies should consider the lived experiences of older adults when addressing public health matters related to sedentary behaviour and physical activity.

Physical activity, sedentary behaviour and well-being: experiences of people with knee and hip osteoarthritis

Living with knee and hip osteoarthritis (OA) means living with pain and difficulty in movement. Given the beneficial effects of physical activity (PA) and reduction of sedentary behaviour (SB), these behaviours need to be understood in the context of individuals' daily lives and sense of well-being. Twelve individuals (age: 43-79 years; 67% female) with knee and/or hip OA purposively selected (e.g., age, OA duration, OA severity) participated in semi-structured interviews. Data was analysed using inductive thematic analysis. PA and SB were narrated as multifaceted experiences with two overarching themes, PA negotiations (valuing mobility, the burden of osteoarthritis, keep going, the feel-good factor), SB negotiations (the joy of sitting, a lot is too bad, the osteoarthritis confines), and two overlapping themes (the life context, finding a balance). Physical and psychological aspects of PA and SB experiences were interwoven. Participants valued mobility and were proactively trying to preserve it by keeping active. A constant negotiation among the OA burden, the need to enjoy life and life circumstances was underlying PA behaviour. Prescription and encouragement of a physically active lifestyle in this population should be linked to mobility-related personal values and sense of well-being, while addressing concerns around OA-safety and normalizing PA trade-offs.

Physical Activity Fragmentation and Falls in Older Adults: Findings From the National Health and Aging Trends Study

BACKGROUND

Physical activity (PA) may be an important fall prevention strategy. Current PA guidelines emphasize total PA dose, but daily patterning of PA is underappreciated. With aging, PA bouts become less frequent and shorter in duration (ie, more fragmented). PA fragmentation may be an indicator of fall risk, but the relationship is not well understood. This study examined daily PA accumulation and patterns with fall risk in older adults.

METHODS

Participants (n = 685, 54.3% women, 61.5% aged 70-79 years) from the National Health and Aging Trends Study with wrist-worn accelerometry PA data from Round 11 (baseline) and sample person interviews with fall data from Round 12 (follow-up) were included. PA variables were categorized into tertiles and incident falls were defined as ≥1 self-reported fall in the year following the PA assessment between baseline and follow-up. A modified Poisson approach was used to estimate the relative risk of both PA accumulation and fragmentation with falls.

RESULTS

Overall, 40.0% reported an incident fall. After adjustment for sociodemographic and health characteristics, those in the highest tertile of total PA accumulation had lower fall risk (aRR = 0.74, 95% CI: 0.57, 0.95) and those in the highest tertile of PA fragmentation had increased fall risk (aRR = 1.33, 95% CI: 1.03, 1.73). Models were attenuated after adjustment for physical functioning.

CONCLUSIONS

PA fragmentation may identify fall risk in older adults. Longitudinal studies are needed to disentangle the temporal sequencing of the complex relationship between PA and physical functioning across the life course.

Exploring the perspectives of older adults who are pre-frail and frail to identify interventions to reduce sedentary behaviour and improve mobility: a thematic content analysis

Older adults who are frail are one of the most sedentary and the least physically active age groups. Prolonged sedentary time is associated with increased risk of negative health outcomes. To help design effective and sustainable content and optimize the uptake of sedentary behaviour interventions, an in-depth understanding of older adults' perceptions of sedentary behaviour is needed; however, most qualitative studies have been conducted in healthy older adults. The aim of this study was to explore perspectives of sedentary behaviour within the context of older adults who are pre-frail and frail after the winter and spring. We included participants if they: (1) spoke English or attended with a translator or caregiver, (2) were ≥ 60 years, and (3) were frail on the Morley Frail Scale. We utilized a qualitative description methodology including a semi-structured in-depth interview and thematic content analysis. Concepts from the COM-B (Capability Opportunity Motivation-Behaviour) model were used to guide the semi-structured interviews and analysis. To ensure credibility of the data, we used an audit trail and analyst triangulation. We recruited 21 older adults (72 ± 7.3 years, 13 females, 13 frail) from southwestern Ontario, Canada. Two individuals were lost to follow-up due to medical mistrust and worse health. We transcribed 39 audio recordings. We identified three salient themes: (1) older adults rationalize their sedentary behaviours through cognitive dissonance (reflective motivation), (2) urban cities in southwestern Ontario may not be "age-friendly" (physical opportunity), and (3) exercise is something people "have to do", but hobbies are for enjoyment despite medical conditions (psychological capability). Perspectives of sedentary behaviour were different in the winter versus spring, with participants perceiving themselves to be less active in winter. Incorporating dissonance-based interventions as part of an educational program could be used to target the reflective motivation and psychological capability components. Future research should consider interdisciplinary collaborations with environmental gerontology to develop age-friendly communities that promote meaningful mobility to target physical opportunity.

Examining Inclusive Language in Clinical Narratives in Medical Biochemistry Textbooks to Model Equitable Patient-Centered Care in Preclinical Undergraduate Medical Education

Purpose

When healthcare professionals use biased or stigmatizing language to describe people or conditions, it can impact the quality of care or erode the patient-physician relationship. It is not clear where healthcare professionals acquire biased and stigmatizing language in practice. This study focuses on examining language in educational materials used in training of medical students. Specifically, medical biochemistry textbooks were examined as they are often a first exposure to clinical narratives and communication standards. The aim of this project is to investigate whether medical biochemistry textbooks, widely recommended in preclinical UME, model inclusive language communication in clinical narratives.

Methods

To determine if educational materials follow inclusive writing guidelines, we conducted a modified document analysis on a sample of medical biochemistry textbooks when clinical scenarios were described. Three independent researchers separately reviewed the textbooks, coded the language using NVivo, and generated themes.

Results

Our results show that medical biochemistry textbooks contain language which is not in alignment with the best practices for inclusive language. Our analysis mapped codes to two primary themes of language misalignment. The first theme, "clinical language" (n = 92), included the following codes: difficult patient, general negative descriptive language, patient as failure, and questioning patient credibility. The second primary theme, "identity-first labeling" (n = 251), included 21 codes.

Conclusion

This study provides early evidence that the language used in medical biochemistry textbooks to describe people and conditions is not in alignment with inclusive language recommendations. This can reinforce the way future healthcare professionals speak to and about their patients.

A behaviour change intervention to reduce sedentary behaviour in chronic obstructive pulmonary disease: a qualitative study

OBJECTIVES

To document the experiences of people with chronic obstructive pulmonary disease (COPD) who underwent a behaviour change intervention to reduce sedentary behaviour (SB) in a clinical trial.

DESIGN AND PARTICIPANTS

Qualitative study using semi-structured interviews to explore perspectives of the behaviour change intervention and specific intervention components in people with stable COPD on the waitlist for pulmonary rehabilitation.

SETTING

Three outpatient pulmonary rehabilitation programmes in Sydney, Australia.

INTERVENTIONS

The six-week behaviour change intervention with once weekly contact with a physiotherapist aimed to reduce SB by replacing it with light-intensity physical activity (PA) and by breaking up prolonged SB.

MAIN OUTCOME MEASURES

Of 30 participants who completed the behaviour change intervention, interviews were conducted with 13 participants and analysed using the 'capability, opportunity, motivation, behaviour (COM-B)' framework of behaviour change.

RESULTS

Intervention components regarded as most helpful by participants were verbal education on health consequences on SB, goal setting, and self-monitoring of, and feedback on, step count using activity trackers. There was a clear preference during goal setting to increase PA rather than to reduce SB. Physical limitations and enjoyment of SB were the most reported barriers to reducing SB.

CONCLUSIONS

Goal setting, verbal education, and self-monitoring of, and feedback on step count, were viewed positively by people with COPD and may show promise for reducing SB and increasing PA based on individual preference. CONTRIBUTION OF THE PAPER.

The Quiet Epidemic: An Overview of Emerging Qualitative Research Trends on Sedentary Behavior in Aging Populations

Sedentary behavior poses a significant health risk to older adults. The purpose of this scoping review is to summarize key findings from qualitative research (since 2012), with a focus on explaining prevailing research trends and patterns within the field. This review included 25 studies that met the strict inclusion criteria. Five key research themes have emerged: (1) defining and shaping perspectives of sedentary behavior, (2) understanding the dynamics of daily routines and contexts, (3) raising awareness of older adults' perceived advantages and disadvantages of sedentary behavior, (4) identifying its determinants and discouraging factors, and (5) exploring interventions to promote active behaviors and reduce sedentary behavior. These themes highlight the multifaceted nature of SB and underscore the importance of tailoring interventions to address individual, social, and environmental issues. A comprehensive understanding of SB is critical to developing effective strategies to promote active lifestyles and reduce SB in older adults. Further qualitative research is needed to deepen our understanding and develop targeted interventions and strategies.

The meaning of sedentary behavior among older adults: a phenomenological hermeneutic study

BACKGROUND

A sedentary lifestyle has implications for health and well-being. For healthy ageing, it is recommended to interrupt prolonged sitting; however, little is known about the meaning of sedentary behavior among older adults. The aim of this study was to understand the meaning of sedentary behavior among older adults with initial support from community care.

METHODS

A phenomenological hermeneutics approach was used, and individual interviews were conducted with sixteen older adults aged 70 to 97 years, by phone and face to face. The older adults lived in ordinary housing in southern Sweden and received initial support from community care.

RESULTS

The interviews yielded three key themes: Being sedentary is an unnatural part of life, having an ageing body means unwanted frailty, and having a sedentary lifestyle is based on conscious choices.

CONCLUSION

Being sedentary means having a lack of physical activity and social interactions, resulting in wanting to be more physically active than sometimes possible. Clinical practitioners should bear in mind that becoming more sedentary is inevitable with an ageing body, but that older adults may have an innate desire to be as physically active as possible. A lifelong exposure to physical activity, the possibility of well-being found in sedentary activities and the impact of social networks should not be overlooked when creating clinical interventions to break unhealthy sedentary behavior among older adults. To increase the understanding of sedentary behavior among older adults, future research could focus on the impact of physical impairment on sedentary behavior and the relationship between sedentary behavior and physical activity throughout life.

Combined influence of sedentary behaviours and chronic pain on depressive symptoms in older Korean adults with hypertension

AIMS

Depressive symptoms in hypertensive patients are linked to poor adherence to treatment. Sedentary behaviours and chronic pain can increase blood pressure and depressive symptoms, respectively. However, the impact of their coexistence on depressive symptoms in older adults with hypertension has not yet been investigated. This study aimed to identify the combined influence of sedentary behaviours and chronic pain on depressive symptoms in older adults with hypertension in Korea.

METHODS AND RESULTS

This cross-sectional study used data from the sixth Korea National Health and Nutrition Examination Survey from January to December 2014. The survey adopted multistage stratified sampling by geographical region, gender, and age. For the data analysis, a total of 573 patients with hypertension aged 65 years or older were included. Approximately, 61.0% of depressed older patients had both sedentary behaviours and chronic pain compared with patients without depressive symptoms. In multivariate logistic regression analysis, compared with patients without either sedentary behaviours or chronic pain, older adults with hypertension who presented both sedentary behaviours, and chronic pain had the highest risk of depressive symptoms (odds ratio = 13.86, 95% confidence interval = 5.87-32.71; P < 0.001).

CONCLUSION

Coexistence of sedentary behaviours and chronic pain in older hypertensive patients may lead to depressive symptoms. Evaluating both sedentary behaviours and chronic pain when assessing depressive symptoms in patients with hypertension would be beneficial in planning a patient-centred approach for controlling blood pressure. More prospective cohort studies with larger samples are required to identify the causal relationships.

Multidimensional Frailty and Lifestyles of Community-Dwelling Older Portuguese Adults

(1) Background: Lifestyles are referred to as conditioning factors for the frailty of older adults. However, there are few studies that explore its association. The objective of the present study is to analyze the association between sociodemographic, clinical, and lifestyle factors of older adults people with multidimensional frailty. (2) Methods: Descriptive and correlational study carried out with older adults people registered in a Health Unit in Portugal. Data were collected through a sociodemographic and clinical questionnaire and application of the Individual Lifestyle Profile and Tilburg Frailty Index to assess the lifestyles and multidimensional frailty of older adults, respectively. This last instrument, being of a multidimensional nature, assesses not only physical, but also psychological and social frailty, with a cut-off point of 6. (3) Results: Of the 300 older adults who participated, most were female (60.3%) and had a mean age of 81.34 ± 6.75 years. Moreover, 60.3% of the sample were frail older adults. Gender, marital status, number of household members, number of chronic diseases, number of daily medications, self-perception of health status and lifestyle and use of a walking device were associated with multidimensional frailty (p ≤ 0.001). Healthy eating habits, physical activity, relational behaviour, preventive behaviour, and stress management were significantly associated with lower physical, psychological, and social frailty (p ≤ 0.001). (4) Conclusions: When community health workers are aware of multidimensional frailty predictors and their components, they can intervene early and, consequently, delay the onset and progression of frailty in older adults.

Examining the independent and interactive association of physical activity and sedentary behaviour with frailty in Chinese community-dwelling older adults

BACKGROUND

While physical inactivity or prolonged sitting has been linked to an increased risk of frailty, the interaction between sitting time (ST), physical activity (PA) and frailty is not well understood. The aim of this study was to examine the dose-response relationship between PA, ST and frailty and further to evaluate the interaction effect of PA and ST on frailty in the context of regular COVID-19 epidemic prevention and control in China.

METHODS

A cross-sectional analysis was performed on 1458 participants (age ≥ 60) enrolled from a prospective cohort study of frailty in elderly people of Fujian Province. PA and ST levels were assessed using the International Physical Activity Questionnaire. A 40-item frailty index (FI) quantified frailty. Multivariable logistic regression and linear regression models were applied to examine the dose-response relationship between PA or ST and frailty level. Interaction plots were used to visualise the interaction effects of PA and ST on frailty.

RESULTS

Compared with light PA, the odds ratios (ORs) for frailty were significantly lower for moderate PA (OR, 0.609 [95% CI, 0.419, 0.885], P < .001) and vigorous PA (OR, 0.399 [95% CI, 0.236,0.673], P < .001). Comparing subjects with ST <  4 h/day, those with ST ≥ 8 h/day were significantly more likely to be diagnosed with frailty (OR, 3.140 [95% CI, 1.932, 5.106], P < .001), 6-8 h/day (OR, 1.289 [95% CI, 0.835, 1.989], P >0.05), and 4-6 h/day (OR, 1.400 [95% CI, 0.972, 2.018], P >0.05). Each one unit increase in metabolic equivalents (h/day) of PA was related to an average 0.928 (0.887, 0.971) decrease in prevalence of frailty, while each one unit increase in sitting time (h/day) was related to average 1.114 (1.046,1.185) increase in prevalence of frailty. Negative interactive effects of PA and ST on frailty were observed (P < 0.001).

CONCLUSION

There are nonlinear and linear dose-response relationships between PA, SB and frailty respectively. In addition, excess ST may counteract the beneficial effects of PA on frailty. Interventions that focus on reducing excess ST may be effective strategies to reduce the risk of frailty and should be taken seriously by public health authorities, especially in the context of regular epidemic prevention and control in China.

Mechanisms of Insulin Resistance at the Crossroad of Obesity with Associated Metabolic Abnormalities and Cognitive Dysfunction

Obesity mediates most of its direct medical sequelae through the development of insulin resistance (IR). The cellular effects of insulin occur through two main postreceptor pathways that are the phosphatidylinositol 3-kinase (PI3-K) and the mitogen-activated protein kinase (MAP-K) pathways. Obesity-related IR implicates the PI3-K pathway that confers the metabolic effects of insulin. Numerous and complex pathogenic pathways link obesity with the development of IR, including chronic inflammation, mitochondrial dysfunction (with the associated production of reactive oxygen species and endoplasmic reticulum stress), gut microbiota dysbiosis and adipose extracellular matrix remodelling. IR itself plays a key role in the development of metabolic dysfunction, including hypertension, dyslipidaemia and dysglycaemia. Furthermore, IR promotes weight gain related to secondary hyperinsulinaemia, with a resulting vicious cycle of worsening IR and its metabolic sequelae. Ultimately, IR underlies obesity-related conditions such as type 2 diabetes mellitus (T2D) and polycystic ovary syndrome (PCOS). IR also underlies many obesity-related malignancies, through the effects of compensatory hyperinsulinaemia on the relatively intact MAP-K insulin pathway, which controls cellular growth processes and mitoses. Furthermore, the emergent data over recent decades support an important role of obesity- and T2D-related central IR in the development of cognitive dysfunction, including effects on hippocampal synaptic plasticity. Importantly, IR is largely reversible through the optimisation of lifestyle factors that include regular engagement in physical activity with the avoidance of sedentariness, improved diet including increased fibre intake and sleep sufficiency. IR lies at the key crossroad between obesity and both metabolic and cognitive dysfunction. Given the importance of IR in the pathogenesis of many 21st century chronic diseases and its eminent reversibility, it is important that we all embrace and facilitate optimised lifestyles to improve the future health and wellbeing of the populace.
