Disability and sleep duration: evidence from the American Time Use Survey

Sleep Duration Differences by Education from Middle to Older Adulthood: Does Employment Stratification Contribute to Gendered Leveling?

Sleep duration changes across the life course and differs by education in the United States. However, little research has examined whether educational differences in sleep duration change over age-or whether sleep duration trajectories over age differ by education. This study uses a life course approach to analyze American Time Use Survey data (N = 60,908), examining how educational differences in weekday sleep duration change from middle to older adulthood (ages 40-79). For men only, differences in total sleep time between individuals with less than a high school degree and those with more education converge in older adulthood. Results suggest that this leveling is explained by decreasing educational stratification in work hours as men enter older adulthood. Findings highlight the importance of employment for shaping gendered socioeconomic differences in sleep and demonstrate differences by education in how sleep duration changes over age, with possible implications for health disparities.

Study on the trajectory of depression among middle-aged and elderly disabled people in China: Based on group-based trajectory model

Background

Previous studies have shown that middle-aged and elderly adults with disabilities are at higher risk for depressive symptoms. However, there are few studies on the long-term trajectories of depressive symptoms in the Chinese middle-aged and elderly disabled population.

Objective

This study aimed to identify the different development trajectories of depressive symptoms and their influencing factors in middle-aged and elderly people with disabilities in China.

Methods

Using data from the China Health and Retirement Longitudinal Study (CHARLS) in 2011, 2013, 2015, and 2018, a longitudinal cohort was formed for the study. A total of 2053 participants underwent at least two measures of depressive symptoms, assessed using the Center for Epidemiological Studies Depression Scale (CES-D10), a depression symptom assessment scale. We constructed a Group-Based Trajectory Model (GBTM) to identify the development trajectory of depressive symptoms in 2053 middle-aged and elderly disabled individuals, screened the potential predictors using lasso regression, and analyzed the factors affecting the development trajectory of depression through multivariate logistic regression.

Results

We identified four depression symptom trajectories throughout the follow-up process: "low depressive symptom group", "worsening depressive symptom group", "relieved depressive symptom group", and "high depressive symptom group". We found that there were differences in basic characteristics among different subgroups of depression trajectory. However, middle-aged and elderly disabled women living in rural areas, with limited ADL or IADL, physical pain, poor self-reported health and self-reported memory, short sleep time, and no relatives and friends to take care of them were the key groups for the prevention and treatment of depressive symptoms.

Conclusion

There is heterogeneity in the trajectories of depressive symptoms in the Chinese middle-aged and elderly disabled population, it is necessary to focus on the characteristics of the trajectories of different subgroups.

Family function, anxiety and depression in adults with disabilities: a network analysis

Background

The prevalence of family dysfunction, anxiety and depression is high in people with disabilities due to long-term activity constraints and social difficulties. Recently, although studies have attempted to provide guidance for family therapy by focusing on the relationship between family function and negative emotions, the specific effects of improved family function during family therapy on alleviation of anxiety and depressive symptoms have been obscured. Thus, this study attempted to elucidate the impact of specific family functioning on specific symptoms of anxiety and depression through network analysis.

Methods

Family APGAR Index Questionnaire (APGAR), Generalized Anxiety Scale (GAD-7), and Patient Health Questionnaire Depression Scale (PHQ-9) were used to survey 897 adults with disabilities in Sichuan Province. Meanwhile, network analysis for studying the relationship between anxiety, depression and family functioning among the disabled via R software.

Results

The network analysis showed that (1) Nodes PHQ4 ("Energy"), APGAR3 ("Growth"), GAD1 ("Nervousness") and GAD4 ("Relaxing Trouble") were central nodes in the network model; (2) Bridge nodes linking family function, anxiety and depressive symptoms in the sample were PHQ9 ("Suicide ideation"), PHQ6 ("Worthlessness"), GAD1 ("Nervousness") and GAD5 ("Restlessness"); (3) The node APGAR5 ("Resolve") directly connects the bridge symptoms PHQ9 ("Suicide ideation") and PHQ8 ("Motor").

Conclusion

This study suggests that therapists could target the resolve of family members during family therapy to reduce suicidal ideation and enhance the level of activity of people with disabilities, thereby improving the network of anxiety and depression symptoms and alleviating negative emotions of people with disabilities.

The Mediating Role of Depression in Association Between Total Sleep Time and Instrumental Activities of Daily Living in China

Objectives: This study aims to investigate the mediating role of depression and the moderating effect of gender in the relationship between total sleep time (TST) and instrumental activities of daily living (IADL) in middle-aged and elderly people (aged 45 or above). Methods: The data used in this study is from the China Health and Retirement Longitudinal Study (CHARLS), including a total of 10,460 respondents. Associations between TST, IADL, depression, and gender were analyzed using logistic regression and Karlson, Holm, and Breen (KHB) methods. Results: Short (OR = 1.42, 95% CI = 1.28-1.58 of ≤6 h) and long TST (OR = 1.16, 95% CI = 1.02-1.32 of 8-9 h; OR = 1.35, 95% CI = 1.19-1.54 of >9 h) were both associated with IADL. The mediation effect analyses observed that depression explained 64.80% of the total effect of short TST (≤6 h) and IADL, but was insignificant in long TST (8-9 h and >9 h). Meanwhile, gender has moderating effects on the mediation effect model. Conclusion: The study suggests that health interventions that focused on the dimensions of TST and depression are crucial for preventing functional disability while accounting for gender differences.

Sleep Quality and Disability for Custodial Grandparents Caregivers in the Southern United States

Sleep quality amongst caregivers with disability may have been compounded by the COVID-19 pandemic. We evaluated differences in sleep quality amongst custodial grandparents from a southern state that were identified through state-based Kinship Care support groups coordinators and online. Participants ( N = 102) completed the Pittsburgh Sleep Quality Index and self-reported disability statuses. Gamma tests showed a strong negative relationship between disability and sleep duration indicating fewer hours of sleep, higher use of sleep medication and greater sleep disturbances. Disability is not significantly related to sleep latency, sleep efficiency, and daytime dysfunction. T-tests showed no strength of relationship between disability and overall sleep quality. During the first year of the COVID-19 pandemic, custodial grandparents with disability had greater issues with their sleep quality than those without disability. Sleep, as it pertains to its overall preponderant role in maintaining good health, should be examined amongst custodial grandparent caregivers and those with disability.

Promoting sleep in low-income older adults with disabilities: Comparing CAPABLE with a social engagement control

Sleep plays a vital role in older adults' health. The Community Aging in Place-Advancing Better Living for Elders (CAPABLE) trial, conducted in Maryland between 2012 and 2016, is a 5-month biobehavioral environmental intervention study to reduce functional disabilities in 300 low-income older adults. Individual and environmental factors impacting sleep were addressed in CAPABLE. This secondary data analysis was to test the preliminary effect of CAPABLE on actigraph-measured sleep, compared with a social engagement control in 73 CAPABLE participants with pretest-posttest actigraph data. Participants in this analysis were aged 75.8±7.5 years; 86.3% of them were females and 84.9% were Black/African Americans. Both CAPABLE intervention and social engagement control improved sleep efficiency and reduced sleep onset latency. The effect of CAPABLE on sleep was comparable to social engagement. These findings underline the importance of promoting physical function and maintaining social activity for sleep in low-income older adults with disabilities.

The influence of total sleep time on chronic disease in people with disabilities in South Korea: an analysis of panel data

STUDY OBJECTIVES

This study examined the relationship between total sleep time and chronic diseases among people with disabilities using data from the Panel Survey of Employment for the Disabled to identify differences according to sex and age.

METHODS

This study analyzed secondary data analysis from the second wave of the Panel Survey of Employment for the Disabled (collected 2016-2018; n = 5,092) using a generalized estimating equation model and chi-square test.

RESULTS

The main findings were these: First, the incidence of chronic disease was 1.84 and 1.24 times higher among patients with disabilities who slept less than 5 and 6 hours per night, respectively, than those who slept 7 hours. Second, female patients experienced more sleep problems than male patients. Third, chronic disease was most prevalent among patients with the shortest sleep time, regardless of age.

CONCLUSIONS

The results suggested that patients with disabilities who slept less than 6 hours per night were more likely to experience chronic diseases than those who slept more than 6 hours, with women especially vulnerable. Future research should consider multiple variables to clarify the relationship between total sleep time and health-related outcomes associated with various disabilities and chronic diseases.

Community-dwelling adults with functional limitations are at greater risk for sleep disturbances

OBJECTIVE

To evaluate whether sleep disturbances vary along a continuum of functional limitations in a large nationally representative sample of US adults.

METHODS

Using 2014-2015 National Health Interview Survey data (n = 33,424), we considered associations between each of 5 sleep disturbance measures (duration, trouble falling asleep, trouble staying asleep, use of sleep medications, waking rested) and Functional Limitations Index score, which distinguishes among adults with little-or-no (least-limited), moderate (somewhat-limited), and high functional limitations (most-limited).

RESULTS

Somewhat-limited and most-limited respondents reported significantly worse sleep health for all sleep disturbance measures than people with little-or-no limitations, even controlling for body mass index, psychological distress, and 14 health indicators.

CONCLUSIONS

People with significant self-reported limitations in physical functioning, independent of specific disabilities or disabling condition, report more sleep disturbances. Clinicians may want to evaluate the sleep health of patients with functional limitations.

Daily Social Life of Older Adults and Vulnerabilities During the COVID-19 Pandemic

Introduction: The social integration of older adults is crucial for understanding their risk of infection and mental health during the COVID-19 pandemic. However, the social lives of older adults differ, which means they are not all vulnerable to COVID-19 in the same way. This study analyzes everyday time use and social contacts of older adults to inform discussions of their vulnerabilities during the pandemic.

Methods: Using the 2019 American time use survey (N = 4,256, aged 55 and older), hurdle model regressions were used to examine the relationship between age, gender, and six indicators of the degree of social contact and time use, including (1) time alone, (2) time spent with family members, (3) time spent with non-family members, (4) time spent with people in the same household, (5) number of public spaces visited, and (6) time spent in public spaces.

Results: Results showed substantial heterogeneity in everyday time use and social contacts. Time in public places gradually decreased from the oldest-old (85 years or older), old-old (75–84 years), to mid-life (55–64 years) adults. The gaps were not explained by age differences in sociodemographic characteristics and social roles. Compared with mid-life adults, time with family members of the young-old and old-old adults decreased, but time with non-family members increased. Age differences in social roles over the life course partially explained the differences.

Conclusions: Should these patterns of time use and social contacts persist during COVID-19; then, such variations in the organization of social life may create different exposure contexts and vulnerabilities to social distancing measures among older adults; such information could help inform interventions to better protect this population.

Relationship between Sleep Duration Trajectories and Self-Rated Depressive Symptoms in South Koreans with Physical Disabilities

Physically disabled persons can have sleep problems, which affects their mental health more than those in non-disabled people. However, there are few studies on the relationship between sleep duration and mental health targeting physically disabled people in South Korea, and existing studies on the disabled have mostly used data collected from convenience rather than nationally representative samples, limiting the generalization of the results. This study used data from the second wave of the Panel Survey of Employment for the Disabled (PSED, 2016-2018, 1st-3rd year). Participants included 1851 physically disabled individuals. The Chi-square test and generalized estimating equation (GEE) were used and the Akaike information criterion (AIC) value and the AIC log Bayes factor approximation were used to select sleep trajectories. This is the first study to elucidate multiple sleep trajectories in physically disabled people in Korea, and the relationship between sleep duration trajectories and self-rated depressive symptoms. People with physical disabilities who sleep more than 9 h have the highest risk of depression and need more intensive management as a priority intervention.

Functional Limitations, Social Integration, and Daily Activities in Late Life

OBJECTIVES

Disability in late life has been associated with increases in receiving care and loss of autonomy. The Disablement Process Model suggests that physical impairments lead to functional limitations that contribute to disabilities in managing household, job or other demands. Yet, we know surprisingly little about how functional limitations are related to activities throughout the day among community-dwelling adults, or the possible moderating role of social integration on these associations.

METHODS

Community-dwelling adults (N = 313) aged 65+ completed a baseline interview assessing their functional limitations, social ties, and background characteristics. Over 5 to 6 days, they answered questions about daily activities and encounters with social partners every 3 hours on handheld Android devices.

RESULTS

Multilevel logistic models revealed that functional limitations are associated with increased likelihood of activities associated with poor health (e.g., TV watching, medical appointments), and reduced likelihood of social activities, or physical activities, chores, or leaving the home. Most moderation analyses were not significant; family and friends did not mitigate associations between functional limitations and daily activities, with the exception of medical appointments. Individuals with functional limitations were more likely to attend medical appointments when with their social partners than when alone.

DISCUSSION

This study provided modest indication that functional limitations in community-dwelling older adults are associated with patterns of activity that may lead to further limitations, disability or loss of autonomy. Findings warrant longitudinal follow-up to establish subsequent patterns of decline or stability.

Does physical ill-health increase the risk of suicide? A census-based follow-up study of over 1 million people

AIMS

Mental ill-health is a known risk factor for suicide mortality. However, the relationship between physical ill-health and suicide is less clear. This study examined the relationship between different aspects of physical ill-health and the risk of suicide death.

METHODS

Data for 1 196 364 adults (aged 18 years and over) were identified from the 2011 Northern Ireland Census and linked to death registrations until the end of 2015. Multivariate logistic regression was used to construct models to test associations with likelihood ratio tests for interactions.

RESULTS

Over one in eight individuals (13.7%) reported multimorbidity (⩾2 physical health conditions) and one in four (25.4%) identified having limitation of daily activities. During follow-up, 51 672 individuals died; 877 due to suicide. The gradient in suicide risk by number of physical conditions disappeared following adjustment for activity limitation. Individuals with a lot of activity limitation were over three times more likely to die by suicide (OR = 3.13, 95% CI 2.50-3.93) compared to those with no limitations though this was reduced to OR = 1.72 (95% CI 1.35-2.20) with adjustment for poor mental health. The relationship between activity limitation and suicide was most pronounced at younger ages (18-34 years).

CONCLUSIONS

This study suggests that it is the effect that physical illness has on a person's life, in terms of disruption to daily activity, rather than the number of conditions that predicts suicide risk, especially at younger ages. Improved awareness and better management of mental wellbeing of individuals with physical health conditions may help to reduce suicides, especially in younger people.

Self-reported short sleep duration among US adults by disability status and functional disability type: Results from the 2016 Behavioral Risk Factor Surveillance System

BACKGROUND

Short sleep duration is associated with an increased risk of chronic disease and all-cause death. A better understanding of sleep disparities between people with and without disabilities can help inform interventions designed to improve sleep duration among people with disabilities.

OBJECTIVE

To examine population-based prevalence estimates of short sleep duration by disability status and disability type among noninstitutionalized adults aged ≥18 years.

METHODS

Data from the 2016 Behavioral Risk Factor Surveillance System were used to assess prevalence of short sleep duration among adults without and with disabilities (serious difficulty with cognition, hearing, mobility, or vision; any difficulty with self-care or independent living). Short sleep duration was defined as <7 h per 24-h period. We used log-binomial regression to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) while adjusting for socioeconomic and health-related characteristics.

RESULTS

Adults with any disability had a higher prevalence of short sleep duration than those without disability (43.8% vs. 31.6%; p < .001). After controlling for selected covariates, short sleep was most prevalent among adults with multiple disabilities (PR 1.40, 95% CI: 1.36-1.43), followed by adults with a single disability type (range: PR 1.13, 95% CI: 1.03-1.24 [for independent living disability] to PR 1.25, 95% CI: 1.21-1.30 [for mobility disability]) compared to adults without disability.

CONCLUSIONS

People with disabilities had a higher likelihood of reporting short sleep duration than those without disabilities. Assessment of sleep duration may be an important component in the provision of medical care to people with disabilities.

Prevalence of Disability and Disability Types by Urban-Rural County Classification-U.S., 2016

INTRODUCTION

In the U.S., disability affects approximately 61.4 million (25.7%) adults, with mobility disability being the most prevalent type, affecting about 1 in 7 U.S. adults. However, little is known about the prevalence of disability and functional disability types by urbanization level.

METHODS

Data from the 2016 Behavioral Risk Factor Surveillance System were analyzed. The prevalences of disability, overall and by functional disability type, were estimated among U.S. adults across 6 levels of urban-rural county categories based on the 2013 National Center for Health Statistics Urban-Rural Classification Scheme for Counties. Adjusted prevalence ratios with 95% CIs were estimated by conducting log-linear regression analyses with robust variance estimator while adjusting for study covariates. Data analyses were conducted in 2018.

RESULTS

The prevalences of having any disability, functional disability type, or multiple disabilities were lowest in large metropolitan centers and fringe metropolitan counties and highest in noncore (rural) counties. After controlling for age, sex, race/ethnicity, education, and federal poverty level, adults living in noncore counties were 9% more likely to report having any disability, 24% more likely to report having 3 or more disabilities, and 7% (cognition) to 35% (hearing) more likely to report specific disability types than the adults living in large metropolitan centers.

CONCLUSIONS

Results of this study suggest that significant disparities in the prevalence of disability exist by level of urbanization, with rural U.S. residents having the highest prevalence of disability. Public health interventions to reduce health disparities could include people with disabilities, particularly in rural counties.

Disability, self-rated health, and time seeking medical care

BACKGROUND

Population-level estimates of patient-reported time seeking medical care in the United States by disability status are unknown.

OBJECTIVE

To estimate the likelihood of seeking medical care on an average day and the number of minutes spent traveling to, waiting for, and receiving medical care among those receiving care, by disability status.

METHODS

Data are analyzed from the nationally representative 2008, 2010, and 2012-2016 American Time Use Surveys. Weighted logistic and linear regression models evaluate the association between sensory, cognitive, physical, or multiple disabilities and time spent seeking medical care, net of age, sex, race/ethnicity, education, employment, nativity, marital status, parental status, income, metropolitan area, and self-rated health.

RESULTS

The presence of a disability positively associates with the likelihood of seeking medical care on an average day. Patients with disabilities spend more total time in medical care than patients without disabilities as a result of longer clinical and travel time. These differences cannot be explained by sociodemographic disparities or by poorer self-rated health.

CONCLUSIONS

Patient time burden is exacerbated by the presence of a disability. It is important to consider disability status along with other social disparities when evaluating the delivery of timely and equitable care.

Sleep duration, health status, and subjective well-being: a population-based study

OBJECTIVE

To evaluate, in a population-based approach, the association of extreme sleep duration with sociodemographic factors, health, and well-being.

METHODS

We analyzed the data from the 2014/2015 Health Survey in the city of Campinas, State of São Paulo, Brazil (ISACamp), performed with 1,969 individuals (≥ 20 years old). Associations between the independent variable and short (≤ 6 hours) and long (≥ 9 hours) sleep were determined using the Rao-Scott chi-square test. The analyses were adjusted with multinomial logistic regression models.

RESULTS

Men, individuals aged 40 to 59, those with higher schooling, those who have one (OR = 1.47, 95%CI 1.02–2.12), two (OR = 1.73, 95%CI 1.07–2.80), or three or more (OR = 1.62, 95%CI 1.16–2.28) chronic diseases, and those with three or more health problems (OR = 1.96, 95%CI 1.22–3.17) were more likely to have a short sleep. The chance of long sleep was higher in widowers and lower in those who have more years of schooling, with higher income, worked, lived with more residents at home, and reported three or more diseases (OR = 0.68, 95%CI 0.48–0.97) and health problems. The chance of either short (OR = 2.41, 95%CI 1.51–3.87) or long sleep (OR = 2.07, 95%CI 1.23–3.48) was higher in unhappy individuals.

CONCLUSIONS

These findings highlight the higher chance of short sleep duration among men, among persons in productive age, and among those with a higher level of schooling in a Brazilian city. The association of short sleep with comorbidities and the association of happiness with extremes of sleep duration were also important results to understand the relation of sleep duration with health and well-being.

Sleeping while disabled, disabled while sleeping

This essay considers areas in which the study of sleep and sleep disorders might profit from the perspective of disability studies, as practiced in the humanities and social sciences. This interdisciplinary perspective considers the social and cultural dimensions of bodily and mental states and conditions that a particular society deems abnormal or impaired, as well as the lived consequences of those determinations. Some sleep disorders are considered disabilities, but almost all disabilities entail some disruption from normal sleeping patterns--whether because of physical pain, exhaustion, and emotional stress of facing obstacles in work and other areas of waking life, or challenging sleeping environments in which many disabled people live. Despite these disruptions, finding adequate nighttime care is often difficult for people with disabilities, and consequently, night is often when social isolation and vulnerability are most profound. In addition, caretakers themselves often find their own sleep profoundly disrupted, whether this occurs in a family setting or an institutional space. Finally, the essay suggests that a disability studies perspective can help us to see that disordered sleep--whether primary or secondary to a disabling condition--can both impact and be shaped by social relationships.

Prevalence and risk factors for myopia in older adult east Chinese population

BACKGROUND

To determine the prevalence and associated factors for myopia and high myopia among older population in a rural community in Eastern China.

METHODS

A community-based, cross-sectional survey was conducted in the Weitang town located in Suzhou, an urban metropolis in East China. A total of 5613 Chinese residents aged 60 years and older were invited to complete a questionnaire and participated in a detailed eye examination,including measurements of visual acuity and refractive error using autorefraction and subjective refraction. Myopia and high myopia was defined as SE < -0.5 diopters (D) and < -5.0 D, respectively.

RESULTS

Among the 5613 participating individuals, 4795 (85.4%) complete refraction data of phakic right eye was included for analysis. The age-adjusted prevalence was 21.1% (95% confidence interval [CI], 19.9-22.2) for myopia and 2.5% (95% CI, 2.1-2.9) for high myopia. The prevalence of myopia tended to increase significantly with age(p < 0.001),and women had a higher rate of myopia than men (p < 0.001). According to multivariate logistic regression analysis, adults who were older (odds ration[OR]:1.05; 95% CI:1.04-1.07), spent more time for sleeping at night (OR:1.12;95% CI: 1.06-1.18),or had cataract (OR:1.60;95% CI:1.36-1.88) and family history of myopia (OR:1.47;95% CI:1.23-1.77), are more susceptible to myopia (p < 0.001). People who had older age, family history, cataract and specially longer night-time sleep duration, would have a higher risk of myopia.

CONCLUSION

Myopia and high myopia among rural old adult population in Eastern China presents common. The current literature unanticipated suggests that there was a positive significant association between prevalence of myopia and night-time sleep duration among adult. Our data provide some evidence of this relationship and highlight the need for larger studies to further investigate this relationship longitudinally and explore mechanism therein.

Sleep duration, life satisfaction and disability

BACKGROUND

Although sleep is considered an essential part of individuals' lives, there are no previous studies analysing how sleep duration affects the levels of life satisfaction reported by males and females with disabilities.

OBJECTIVE/HYPOTHESIS

To analyse and compare the impact of hours of sleep on life satisfaction scores reported by people without and with disabilities (stratified by sex) in Germany.

METHODS

Using data taken from the German Socio-Economic Panel for the period 2008-2013, we estimate life satisfaction equations for males and females (running a fixed-effects model) which include a set of variables measuring the number of sleep hours on workdays and weekends.

RESULTS

A higher number of sleep hours on workdays increase life satisfaction for all males and females. However, the contribution of each hour of sleep on workdays is greater for males with disabilities in terms of life satisfaction, whereas for females no significant differences by disability status have been found. Although sleep hours on weekends also increase life satisfaction, the magnitude of the coefficients is relatively higher than that found for the corresponding hours of sleep on workdays, but only for the male sample (disabled or not).

CONCLUSIONS

The participation and commitment of policymakers, governments, trade unions, employers, and health care professionals are key aspects for developing and formulating new guidelines and specific measures that promote a healthy lifestyle and increase sleep duration. Such guidelines and measures are of essence for people with disabilities who are employed (e.g. using brief sleep opportunities during prolonged work periods, which can contribute to reducing fatigue, stress and anxiety).

The impact of sleep duration on recovery post-hip fracture among older diabetic adults in Taiwan

This study explored postoperative changes in sleep duration and physical activity and their relationships with physical function recovery, the muscular strength of the affected side and blood glucose control in elderly adults (n = 41) with diabetes mellitus (DM) who underwent surgery for hip fracture. Thirty-two participants (78.0%) had abnormal sleep durations for at least two time points, and they all had low physical activity levels (an average of 1348.2 kcal/day for the first month, 1377.9 kcal/day for the third month, and 1389.1 kcal/day for the sixth month) during the six months post-hip fracture. The participants with normal sleep durations showed greater femoral muscle improvement on the affected side (adduction: β = 3.70, p = 0.029; abduction: β = 7.25, p = 0.016) and better blood glucose control before meals (β = -73.29, p < 0.001) and after meals (β = -47.90, p = 0.007) compared with those with abnormal sleep durations. Those with higher physical activity levels had better physical function recovery.
