Decomposition Analysis of Depressive Symptom Differences Among Older Adults With Hypertension Between Urban and Rural Areas: Cross-Sectional Study.

Hypertension is the most prevalent chronic disease among China's older population, which comprises a growing proportion of the overall demographic. Older individuals with chronic diseases have a higher risk of developing depressive symptoms than their healthy counterparts, as evidenced in China's older population, where patients with hypertension exhibit varying rates of depression depending on residing in urban or rural areas. This study aimed to investigate factors influencing and contributing to the disparities in depressive symptoms among older urban and rural patients with hypertension in China. We used a cross-sectional study design and derived data from the 8th Chinese Longitudinal Health Longevity Survey of 2018. The Fairlie model was applied to analyze the factors contributing to disparities in depressive symptoms between urban and rural older populations with hypertension. The sample size for this study was 5210, and 12.8% (n=669) of participants exhibited depressive symptoms. The proportions of depressive symptoms in rural and urban areas were 14.1% (n=468) and 10.7% (n=201), respectively. In rural areas, years of education (1-6 years: odds ratio [OR] 0.68, 95% CI 1.10-1.21; ≥7 years: OR 0.47, 95% CI 0.24-0.94), alcohol consumption (yes: OR 0.52, 95% CI 0.29-0.93), exercise (yes: OR 0.78, 95% CI 0.56-1.08), and sleep duration (6.0-7.9 hours: OR 0.29, 95% CI 0.17-0.52; 8.0-9.9 hours: OR 0.24, 95% CI 0.13-0.43; ≥10.0 hours: OR 0.22, 95% CI 0.11-0.41) were protective factors against depressive symptoms in older adults with hypertension, while gender (female: OR 1.94, 95% CI 1.33-2.81), self-reported income status (poor: OR 3.07, 95% CI 2.16-4.37), and activities of daily living (ADL) dysfunction (mild: OR 1.69, 95% CI 1.11-2.58; severe: OR 3.03, 95% CI 1.46-6.32) were risk factors. In urban areas, age (90-99 years: OR 0.37, 95% CI 0.16-0.81; ≥100 years: OR 0.19, 95% CI 0.06-0.66), exercise (yes: OR 0.33, 95% CI 0.22-0.51), and sleep duration (6.0-7.9 hours: OR 0.27, 95% CI 0.10-0.71; 8.0-9.9 hours: OR 0.16, 95% CI 0.06-0.44; ≥10.0 hours: OR 0.18, 95% CI 0.06-0.57) were protective factors, while years of education (1-6 years: OR 1.91, 95% CI 1.05-3.49), self-reported income status (poor: OR 2.94, 95% CI 1.43-6.08), and ADL dysfunction (mild: OR 2.38, 95% CI 1.39-4.06; severe: OR 3.26, 95% CI 1.21-8.76) were risk factors. The Fairlie model revealed that 91.61% of differences in depressive symptoms could be explained by covariates, including years of education (contribution 63.1%), self-reported income status (contribution 13.2%), exercise (contribution 45.7%), sleep duration (contribution 20.8%), ADL dysfunction (contribution -9.6%), and comorbidities (contribution -22.9%). Older patients with hypertension in rural areas had more depressive symptoms than their counterparts residing in urban areas, which could be explained by years of education, self-reported income status, exercise, sleep duration, ADL dysfunction, and comorbidities. Factors influencing depressive symptoms had similarities regarding exercise, sleep duration, self-reported income status, and ADL dysfunction as well as differences regarding age, gender, years of education, and alcohol consumption.

Impact of Pain on Activities of Daily Living in Older Adults: A Cross-Sectional Analysis of Korean Longitudinal Study of Aging (KLoSA).

Pain, particularly musculoskeletal (MSK) and multi-site pain, significantly impacts activities of daily living (ADL) in the elderly, leading to a decline in overall quality of life (QoL). This study, comprising 7490 participants, (mean age: 69 ± 10; females: 57%) from the sixth wave of the Korean Longitudinal Study of Aging (KLoSA), aimed to assess the association between self-reported pain and ADL impairment among the elderly population. Notably, 62% of participants reported experiencing pain, with back pain being the most prevalent (36%) and stomachache the least (0.39%). A majority (61%) of individuals reported MSK-related pain. Additionally, 20% reported pain at one site and 0.03% experienced pain at 12 sites. ADL impairment was observed in 376 (5.0%) participants. Compared to those without pain, participants reporting moderate and severe pain had higher odds of ADL impairment [2.31 (95% CI, 1.66-3.21) and 2.98 (95% CI, 1.95-4.53), respectively]. Pain experienced in the shoulder, arm, wrist, back, hip, leg, and ankle had a significant association with ADL impairment, with ORs ranging from 2.66 (95% CI, 1.80-3.93; hip pain) to 1.36 (95% CI 1.07-1.72; back pain). Furthermore, multi-site pain was associated with higher ADL impairment [1-6 sites: OR: 1.49 (95% CI, 1.11-2.01); 7-12 sites: OR: 7.16 (95% CI, 3.60-14.26)]. These findings underscore the importance of addressing MSK and multi-site pain through targeted interventions, potentially enhancing ADL and contributing to an improved QoL among the elderly population.

Abstract PO5-11-07: Short- and long-term treatment-related effects on physical health in breast cancer survivors

Abstract Background. Breast cancer (BC) survivors experience greater physical health declines compared to cancer-free women of the same age, which is thought to be caused by their cancer and its treatment. However, the short- and long-term effects of different types of treatment on physical health are not well understood, especially for hormone therapy. Moreover, whether specific aspects of physical health, such as activities of daily living (ADL), are affected by treatment is unknown. Methods. This analysis was conducted in the Cancer Prevention Study 3 (CPS-3), a prospective cohort study with approximately 300,000 participants enrolled between 2006-2013. Participants returned a baseline survey and triennial follow-up surveys beginning in 2015. Incident, non-metastatic, female BC patients were included in this analysis if they returned a survey at least 90 days after their diagnosis through June 30, 2020, the end of follow-up for this analysis. All 2,551 BC patients included in this study had pre- and post-diagnostic surveys and underwent breast surgery if they were diagnosed with invasive disease. They were matched to up to five cancer-free women on age and year of survey returns (N=12,704). Self-reported physical health and ADL were assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Scale instrument. Treatment information was obtained from cancer registries and self-report and included surgery, chemotherapy, radiation and hormonal therapy. Odds Ratios (OR) and 95% confidence intervals (CI) between treatment received and self-reported physical function were estimated using multivariable ordinal logistic regression models at three time points relative to the case’s diagnosis date: before diagnosis, within 90 days to 5 years after diagnosis, and more than 5 years after diagnosis. Results. Median age at diagnosis was 56 years (interquartile range (IQR): 50-62). Approximately 82% of the tumors were hormone-receptor positive. The median times from the three physical health measurements to diagnoses were 1.7 years before diagnosis (IQR: 0.9 – 2.7), 1.7 years (IQR: 0.9 – 2.5) from 90 days to 5 years post-diagnosis and 6.6 years (IQR: 5.5-7.0) for more than 5 years post-diagnosis. There was a significant risk of physical decline within 5 years of diagnosis for women who received chemotherapy or hormonal therapy compared to cancer-free women (Table 1). However, more than 5 years after diagnosis, the risk of physical decline was only observed among those who received chemotherapy. Treatment combinations that included chemotherapy were also associated with a decline in the ability to carry out ADL during the first 5 years. Patients who received hormonal therapy without chemotherapy were comparable to cancer-free women in their ability to carry out ADL during the post-diagnosis period. BC patients who received surgery only or surgery and radiation reported physical health and ADLs similar to cancer-free women within 5 and >5 years after diagnosis. Conclusions. Post-diagnosis physical health decline is time and treatment dependent. Patients receiving chemotherapy have the greatest overall physical health decline and it is long-lasting. Beyond five years from diagnosis, physical health of breast cancer patients who did not receive chemotherapy were similar to cancer-free women. Strategies are needed to help BC patients receiving chemotherapy overcome the long-term physical function limitations of their cancer treatment. Table. Associations between treatment received and physical health and ability to carry out activities of daily living. OR: Odds Ratio; CI: confidence interval; chemo: chemotherapy; radio: radiation therapy; horm: hormonal therapy. *Associations were adjusted for matching factors, which included age and time from diagnosis to measurement of physical health.

Abstract 2228: Long-term trajectories of functional disability in older adults with cancer

Abstract Background: Older individuals with cancer history have lower risk of developing Alzheimer’s disease (AD). Cognitive impairment is associated with lower functioning in Instrumental Activities of Daily Living (IADL) and Activities of Daily Living (ADL). However, little is known about long-term IADL and ADL trajectories among individuals with cancer, hindering understanding of the underlying biological mechanisms between cancer and AD. We investigated the long-term functional disability trajectories of adults with cancer, comparing them with similarly aged individuals without a cancer diagnosis. Methods: Our study included 16,006 individuals aged 50 and older without a cancer history at baseline from the Health and Retirement Study. Biennial assessments were conducted from 1998 to 2020, including self-reported cancer status, IADL, and ADL. Linear probability models with repeated measures were used to assess IADL and ADL independence probabilities, adjusting for demographic and socioeconomic covariates. Results: Among 16,006 participants (mean [SD] baseline age, 66.1 [9.9] years; 9,169 [57.3%] female), 3,723 (23.3%) reported a cancer diagnosis during follow-up. Before cancer diagnosis, individuals who later developed cancer had a higher probability of IADL independence and experienced a slower decline in independence compared to their similarly aged counterparts who remained cancer-free. Probability of IADL independence was 0.05 lower immediately after cancer diagnosis compared to the pre-cancer phase, followed by accelerated independence losses relative to the pre-cancer period. After diagnosis, the rate of decline in probability of IADL independence remained slower for individuals with cancer than their cancer-free counterparts, but differences in the rate of decline were smaller than prior to cancer diagnosis. Similar trends were observed for ADL independence. Conclusions: We observed a decline in both IADL and ADL independence around the time of cancer diagnosis, possibly attributed to treatments. Overall, individuals with cancer experienced a more gradual loss in functional independence compared to individuals who remained cancer-free, consistent with the documented inverse association between cancer and AD.

Longitudinal Association of Health Satisfaction With Functional Status and Income Satisfaction in Stroke Survivors.

Although cross-sectional studies have reported the relationships among performance of activities of daily living (ADLs), income satisfaction, and health satisfaction, longitudinal associations in stroke survivors remain unclear. To examine the effects of ADL function and income satisfaction on health satisfaction over time in stroke survivors. Retrospective longitudinal study designs with latent growth curve models (LGMs) to control for time-varying and time-invariant covariates. Community. A total of 198 stroke survivors. Self-reported ADL performance, income satisfaction, and health satisfaction. The average age of participants was 70.68 yr (SD = 8.09; 107 men, 91 women). Each LGM showed that an increase in ADL score (standardized β = 0.116∼0.296, all ps < .05) and income satisfaction (standardized β = 0.513∼0.726, all ps < .001) positively predicted health satisfaction over time, even after controlling for time-varying annual income, demographics, and behavioral characteristics. The fit results of all LGMs were within the acceptable range: χ2(47) = 66.378, p = .0327; χ2(47) = 57.742, p = .1355; root-mean-square error of approximation, <0.08; comparative fit index and Tucker-Lewis index, >0.90; standardized root-mean-square residual, <0.05. Because ADLs are significant modifiable health satisfaction factors, occupational therapy practitioners would need to focus more closely on ADL training in clinical settings. Furthermore, referring those clients to appropriate vocational rehabilitation to improve their income satisfaction would be necessary. Plain-Language Summary: This study recognizes the unique challenges and opportunities that arise when stroke survivors are preparing to return to their communities by emphasizing the significance of ADL training and income satisfaction during this stage of recovery. The study suggests that the therapeutic use of ADL training and income satisfaction could increase health satisfaction for stroke survivors. Therefore, comprehensive ADL training, as an occupational therapy intervention, could be crucial for stroke survivors who are preparing to return to their community from a clinical setting. Furthermore, connecting with vocational rehabilitation could also be important for improving income satisfaction for stroke survivors who are preparing to return to a community.

Effectiveness of an individualised occupational therapy intervention programme (ABLE) using adaptational strategies on activities of daily living among persons with chronic conditions: A randomised controlled trial (RCT).

Compare the effectiveness of a problem-solving, individualised, home-based occupational therapy intervention (ABLE 2.0), to usual occupational therapy, on activities of daily living (ADL) ability in persons with chronic conditions. A single-centre, double-blinded, randomised controlled trial with 10- and 26-week follow-up. A Danish municipality. Persons with chronic conditions experiencing problems performing ADL tasks (n = 80). ABLE 2.0 was compared with usual occupational therapy. Coprimary outcomes were self-reported ADL ability (ADL-Interview Performance) and observed ADL motor ability (Assessment of Motor and Process Skills) at Week 10. Secondary outcomes were self-reported ADL ability (ADL-Interview Performance) and observed ADL motor ability (Assessment of Motor and Process Skills) at Week 26, and perceived satisfaction with ADL ability (ADL-Interview Satisfaction) and observed ADL process ability (Assessment of Motor and Process Skills) at Weeks 10 and 26. In total, 78 persons were randomly assigned: 40 to usual occupational therapy and 38 to ABLE 2.0. No statistically significant nor clinically relevant difference between group mean changes in primary outcomes was identified from baseline to Week 10 (ADL-Interview Performance [-0.16; 95% CI: -0.38 to 0.06] and Assessment of Motor and Process Skills ADL motor ability [-0.1; 95% CI: -0.3 to 0.1]). At Week 26, a statistically significant and clinically relevant difference was found in Assessment of Motor and Process Skills ADL motor ability (LS mean change: -0.3; 95% CI: -0.5 to -0.1) between groups. ABLE 2.0 was effective in improving observed ADL motor ability at 26 weeks.

Dependency in Activities of Daily Living During the First Year After Stroke.

Background: Dependency in personal activities of daily living (ADL) is a common short-term and long-term consequence of stroke and requires targeted rehabilitation. As the duration of hospital stay has become shorter in recent decades, early identification of patients who require rehabilitation has become vital. To our knowledge, no study has investigated whether ADL dependency in the very early stages after admission to the stroke unit can explain ADL dependency 3 and 12 months later. This knowledge would facilitate planning for very early discharge and patient-centered rehabilitation.Objective: This study evaluated whether ADL dependency within 2 days after stroke could explain ADL dependency at 3 and 12 months after stroke.Methods: This longitudinal cohort study included patients with stroke who were treated at a stroke unit in the Sahlgrenska University Hospital (Gothenburg, Sweden) between May 2011 and March 2016. The primary independent variable was ADL dependency at 36–48 h after admission to the stroke unit, which was assessed using a Barthel Index (BI) score of ≤90. The dependent variables were self-reported personal ADL dependency at 3 and 12 months after stroke. Binary logistic regression analyses were performed.Results: Of 366 eligible patients (58% male; median age 71 years), a majority (76%) had mild stroke and 60% were ADL dependent 36–48 h after stroke. Univariable and multivariable logistic regression analyses showed that patients who were dependent within the first 2 days after stroke had higher odds for being dependent 3 months as well as 12 months after stroke.Conclusion: The results indicated that dependency in personal ADL during the first 2 days can explain dependency at 3- and 12-month post-stroke. Therefore, early ADL assessments post-stroke can be used for understanding rehabilitation needs after stroke.

Menstrual and reproductive factors and limitations in activities of daily living: A case–control study within the Japan Public Health Center‐based Prospective Study

Although menstrual/reproductive factors are known to be associated with physical disability, little is known about these associations in relation to activities of daily living (ADL). This study aimed to clarify associations between menstrual/reproductive factors and ADL limitations in peri- and postmenopausal women. A nested case-control study of the Japan Public Health Center-based Prospective (JPHC) Study. The main outcome measure was self-reported ADL levels in the 10-year follow-up questionnaire survey of the JPHC Study conducted between 2000 and 2004 (N=36 460). Women who "live inside almost independently, but go out with assistance" or had a lower level of activity were considered to have ADL limitations ("cases"), and all others served as controls. Candidate menstrual/reproductive predictors were as follows: menarcheal age, menopausal status, menopausal age, regularity of menses, menstrual cycle, number of pregnancies, age at first pregnancy, number of deliveries, age at first delivery, and breast feeding. Multiple logistic regression analyses were conducted, and odds ratios adjusted for age and past lifestyle were calculated. Mean ages of cases (N=592) and controls (N=38 656) were 68.3 (SD=7.6) and 61.1 (SD=7.7) years, respectively. With respect to menopausal age, groups aged <45 and ≥55 years had significantly higher adjusted ORs (1.44, 95% CI: 1.09-1.90 and 1.55, 95%CI: 1.09-2.18, respectively) than the reference group (50-54 years). Multiparous women had significantly lower ORs than nulliparous women. Our findings suggest that menopausal age and parity may predict future ADL limitations in women.

Associations of Long-term Air Pollution Exposure and Incident Late-Life Disability in Older U.S. Adults: The Health Retirement Study

BACKGROUND AND AIM: Late-life disability is of critical concern to older adults and can reflect the cumulative burden of chronic disease over the lifespan. Although air pollution has been associated with many common chronic conditions, associations with disability are understudied. We aimed to quantify associations between long-term exposures to air pollution and late-life disability. METHODS: We used biennial data between 2000 and 2016 on self-reported Activities of Daily Living (ADL) from participants 65 years from the nationally representative Health and Retirement Study. Using a spatiotemporal prediction model, we estimated 10-year PM2.5, PM10-2.5, NO2, and O3 concentrations at participant residences. We then estimated the risk of incident ADL disability as a function of time-varying air pollution, adjusting for individual and area-level confounders and sampling weights in a Cox model. We fitted single- and two-pollutant models. RESULTS:Our study population of 16,927 adults (70+6.4 years) was predominantly non-Hispanic White (76%), Non-Hispanic Black (14%), and Hispanic White (8%) and 32% reported a new disability during follow-up. Overall, we found some evidence that air pollution was associated with an increased risk of ADL disability. After adjustment for place and PM2.5, we found that interquartile increases in PM10-2.5 and NO2 were associated with 8% (HR: 1.08 per 5 µg/m3, 95% CI: 1.01, 1.17) and 9% (HR: 1.09 per 6 ppb, 95% CI: 1.00, 1.19) greater hazards of ADL, respectively, with similar findings in the single pollutant models. PM2.5 and O3 were not associated with higher hazards of ADL in single or multipollutant models after detailed adjustment for place. CONCLUSIONS:This prospective study in a nationally representative sample of older adults found some evidence that higher levels of some but not all long-term air pollutants assessed are associated with increased risk of late-life disability.

MO612THE ROLE OF MECHANICAL MUSCLE POWER IN PHYSICAL DYSFUNCTION: A MODEL FOR TAILORING RESISTANCE-BASED REHABILITATION IN CHRONIC KIDNEY DISEASE

Abstract Background and Aims Individuals living with CKD are characterised by adverse changes in physical function. Knowledge of the factors that mediate impairments in physical functioning is crucial for developing effective interventions that preserve mobility and future independence. Mechanical muscle power describes the rate of performing work and is the product of muscular force and velocity of contraction. Muscle power has been shown to have stronger associations with functional limitations and mortality than sarcopenia in older adults. In CKD, the role of mechanical muscle power is poorly understood and is overlooked as a target in many rehabilitation programmes, often at the expense of muscle mass or strength. The aims of this study were to 1) explore the prevalence of low absolute mechanical power, low relative mechanical power, and low specific mechanical power in CKD; and 2) investigate the association of mechanical power with the ability to complete activities of daily living and physical performance. Method Mechanical muscle power (relative, allometric, specific) was calculated using the sit-to-stand-5 (STS5) test as per previously validated equations. Legs lean mass was derived from regional analyses conducted using bioelectrical impedance analysis (BIA). Physical performance was assessed using two objective tests: usual gait speed and the ‘time-up-and-go’ (TUAG) test. Self-reported activities of daily living (ADLs) were assessed via the Duke Activity Status Index (DASI). Balance and postural stability (postural sway and velocity) was assessed using a FysioMeter. Sex-specific tertiles were used to determine low, medium and high levels of relative STS power and its main components. Results 102 participants with non-dialysis CKD were included (mean age: 62.0 (±14.1) years, n=49 males (48%), mean eGFR: 38.0 (±21.5) ml.min.1.73m2). The mean estimated relative power was 3.1 (±1.5) W.kg in females and 3.3 (±1.3) W.kg in males. Low relative power was found in 35/102 (34%) patients. Relative power was a significant independent predictor of self-reported ADLs (via the DASI) (B=.413, P=.004), and performance on the TUAG (B=-.719, P&amp;lt;.001) and gait speed (B=.404, P=.003) tests. Skeletal muscle mass was not associated with the DASI or any of the objective function tests Conclusion Patients presenting with low muscle power would benefit from participation in appropriate interventions designed to improve the physiological components accounting for low relative muscle power. Assessment of power can be used to tailor renal rehabilitation programmes as shown in Figure 1. Incorporation of power-based training, a novel type of strength training, designed by manipulating traditional strength training variables and primarily movement velocity and training intensity may present the best strategy for improving physical function in CKD.

Impaired hand function and performance in activities of daily living in systemic lupus erythematosus, even in patients achieving lupus low disease activity state (LLDAS).

ObjectiveThe aim was to examine hand function and performance in activities of daily living (ADL) in patients with SLE vs healthy controls, and any associations with demographic and disease-related characteristics.MethodsHand function (grip strength, pinch strength and dexterity) and ADL performance were evaluated in 240 patients with SLE and 122 age- and biological sex-matched healthy controls. Grip strength, pinch strength and dexterity were measured by Jamar dynamometer, pinch gauge and Purdue pegboard test, respectively. Self-reported ADL performance was assessed by disabilities of the arm, shoulder and hand (DASH) and HAQ. Regression analysis was performed to assess the determinants of hand dysfunction.ResultsAll hand function and ADL performance variables were significantly impaired in the entire SLE cohort and the subgroup of patients achieving lupus low disease activity state (LLDAS; n = 157) compared with healthy subjects (P < 0.05). Joint pain, often underestimated in SLE, was the major determinant of hand function and ADL performance in multiple regression models. In addition, age was correlated with grip strength and Purdue scores, gender with grip strength, arthritis with DASH and HAQ, and use of immunosuppressives with DASH, HAQ and grip strength. Likewise, in patients in LLDAS, painful joints were correlated with DASH and HAQ, age with grip strength and Purdue (P < 0.001), gender with grip strength, and immunosuppressives with HAQ and grip strength.ConclusionHand function and performance of daily activities are significantly impaired in SLE, even in patients who achieve LLDAS, suggesting the need for their evaluation and management in clinical practice.

Difficulty in activities of daily living and falls in patients undergoing hemodialysis: A cross-sectional study with nondialysis controls.

Impaired activities of daily living (ADL) and falls are important issues in hemodialysis patients. So far, information is limited regarding self-reported difficulty with ADL (ADL difficulty) in hemodialysis patients. Then, we compared the degree of ADL difficulty and the prevalence of fallers between hemodialysis patients and a nondialyzed control group. Also, the possible association between ADL difficulty and falls was examined. This was a single center, cross-sectional study including two groups of outpatients aged 50 years or older; 209 prevalent hemodialysis patients, and 139 nonrenal patients with diabetes mellitus, hypertension, and/or dyslipidemia (control group). ADL difficulty score was evaluated by a 48-item questionnaire including six subscales of ADLs namely locomotion, eating, toileting, dressing, bathing, and grooming. Experience of falls in the previous year period was examined by a questionnaire. The two groups did not differ significantly in age or sex. The hemodialysis group had a higher median (interquartile range) total score of ADL difficulty than the control group [10 (2-39) vs. 2 (0-10); p < 0.001] and a higher prevalence of fallers (73/209, 34.9% vs. 16/139, 11.5%; p < 0.001). In multivariable-adjusted linear regression analyses, history of falls was independently associated with a higher score of ADL difficulty for total or each of the six subscales. The hemodialysis patients had a significantly higher ADL difficulty and a higher prevalence of fallers than the control group. Self-reported ADL difficulty and falls were closely linked regardless of the patient group.

New Insights into Activities of Daily Living Performance in Chronic Obstructive Pulmonary Disease.

PurposeThere have been calls for more knowledge of activities of daily living (ADL) performance in order to address interventions in pulmonary rehabilitation effectively. Everyday technology (ET) has become an integrated dimension of ADL, impacting the ways in which ADL is performed. To improve everyday functioning and quality of life, the use of ADL and ET use needs to be evaluated and addressed effectively in interventions. Therefore, the aim of this study was twofold: 1) to explore the quality of ADL performance, and 2) to investigate the relationship between observation and self-reported ADL performance and ability to use everyday technologies in people living with COPD.MethodsThis cross-sectional study involved 84 participants aged 46–87 years. Participants were recruited through healthcare centres in the Northern Region of Denmark using a convenience sampling procedure. Data were collected using standardized assessments that investigated different ADL perspectives: self-reported ADL tasks and ET use, observed motor and process ability, and need for assistance. Data were analysed and presented using descriptive statistics and Pearson’s correlation coefficient.ResultsThe most affected ADL tasks were mobility within or outside the home, lower dressing, bathing, pedicuring, cooking, shopping, cleaning and washing clothes. New insights into the quality of ADL performance in people living with COPD were presented in terms of detailed ADL motor skills and ADL process skills, as well as the predicted need for support to function in the community. Moreover, new insights into the relationship between observation and self-reported ADL performance (r=0.546, p<0.01; r=0.297, p<0.01) and between ADL performance and self-perceived ability to use ET (r=0.524, p<0.01; r=0.273, p<0.05; r=0.044, p=0.692) were presented.ConclusionOverall, the knowledge from the present study is valuable for focusing interventions that address challenging ADL performance and ET use through relevant and realistic activities. The ability to use ET is important to evaluate and target pulmonary rehabilitation.

Muscle Mass Assessed by the D3-Creatine Dilution Method and Incident Self-reported Disability and Mortality in a Prospective Observational Study of Community-Dwelling Older Men.

Whether low muscle mass is a risk factor for disability and mortality is unclear. Associations between approximations of muscle mass (including lean mass from dual-energy x-ray absorptiometry [DXA]), and these outcomes are inconsistent. Muscle mass measured by deuterated creatine (D3Cr) dilution and appendicular lean mass (ALM, by DXA) were assessed at the Year 14 Visit (2014-2016) of the prospective Osteoporotic Fractures in Men study (N = 1,425, age 77-101 years). Disability in activities of daily living (ADLs), instrumental ADLs, and mobility tasks was self-reported at the Year 14 visit and 2.2 years later; deaths were centrally adjudicated over 3.3 years. Relative risks and 95% confidence intervals (CI) were estimated per standard deviation decrement with negative binomial, logistic regression, or proportional hazards models. In age- and clinical center-adjusted models, the relative risks per decrement in D3Cr muscle mass/wgt was 1.9 (95% CI: 1.2, 3.1) for incident self-reported ADL disability; 1.5 (95% CI: 1.3, 1.9) for instrumental ADL disability; and 1.8 (95% CI: 1.5, 2.2) for mobility disability. In age-, clinical center-, and weight-adjusted models, the relative risks per decrement in D3Cr muscle mass was 1.8 (95% CI: 1.5, 2.2) for all-cause mortality. In contrast, lower DXA ALM was not associated with any outcome. Associations of D3Cr muscle mass with these outcomes were slightly attenuated after adjustment for confounding factors and the potentially mediating effects of strength and physical performance. Low muscle mass as measured by D3Cr dilution is a novel risk factor for clinically meaningful outcomes in older men.

Changes in problematic activities of daily living in persons with COPD during 1 year of usual care.

Persons with chronic obstructive pulmonary disease (COPD) are often limited in performing their activities of daily living (ADLs). However, it remains unknown whether and to what extent problematic ADLs change over time and whether exacerbation-related hospitalisations affect problematic ADLs. Therefore, we investigated self-reported problematic ADLs of persons with COPD during 1year of usual care (i.e. without a specific experimental intervention). Stable persons with moderate to very severe COPD (n=137) were included in this longitudinal study (registered in the Dutch Trial Register [NTR 3941]). Participants were visited at home at baseline and after 1year. Participants with an exacerbation-related hospitalisation during follow-up were visited additionally within 2weeks after hospital discharge. During all visits, participants' personalised problematic ADLs were assessed using the Canadian Occupational Performance Measure (COPM), and perceived performance and satisfaction of important problematic ADLs were rated on a 10-point scale. In total, 90% of the participants reported at least one new important problematic ADL after 1year. In the subgroup of participants with an exacerbation-related hospitalisation (n=31), 92% of the participants reported new problematic ADLs 2weeks after discharge and 90% reported new problematic ADLs again after 1year. Only the satisfaction score of problematic ADLs as mentioned during baseline improved after 1-year follow-up in all participants (p=.002) and in participants without an exacerbation-related hospitalisation (n=106; p=.014). Problematic ADLs changed during 1year of usual care, which underlines the need for regular assessment of problematic ADLs and referral to treatment options like monodisciplinary occupational therapy and/or a comprehensive pulmonary rehabilitation programme.

The Glittre ADL-Test Differentiates COPD Patients with and without Self-Reported Functional Limitation

The Glittre ADL-test is based on important and common activities of daily living (ADLs), and it is an useful test to objectively distinguish patients with and without self-reported functional limitations. This study aims to analyze if difficulty to perform ADLs, as self-reported by patients with COPD, would reflect a worse Glittre ADL-test performance. In the first visit, patients were evaluated for clinical and nutritional status, spirometry, maximal cardiopulmonary exercise test on a treadmill. One week later, the patients performed two Glittre ADL-tests. Maximal voluntary ventilation (MVV) and the VEGlittre/MVV, VO2Glittre/VO2peak, and HRGlittre/HRpeak ratios were calculated to analyze the ventilatory, metabolic, and cardiac reserves. The London Chest Activity of Daily Living (LCADL) scale was only answered after the two Glittre ADL-test were performed. Patients were splited into two subgroups based on the anchor question of the LCADL: those with and those without self-reported ADL limitation. Sixty-two COPD patients were included (65.3 ± 8.6 years, FEV1 62 ± 22%pred). Those with ADL limitation (39 patients) completed the Glittre ADL-test with a significantly longer time (p = 0.002), as well as higher VEGlittre/MVV (p = 0.005) and lower oxygen pulse (p = 0.021) than those without ADL limitation. The time spent to perform the Glittre ADL-test was significantly associated with total LCADL score (ρ = 0.327, p < 0.05). A cutoff of 253 s was able to distinguish those patients without and with ADL limitation. COPD patients who self-reported ADL limitation according to the LCADL scale took a longer time to perform the Glittre ADL-test with higher VEGlittre/MVV and lower oxygen pulse than those without ADL limitation.

Age, Period, and Cohort Effects on Activities of Daily Living, Physical Performance, and Cognitive Functioning Impairment Among the Oldest-Old in China.

The aim of this study was to examine the trends in impairment regarding activities of daily living (ADL), physical performance, and cognitive function among the oldest-old (those aged 80 and older) in China between 1998 and 2014. We used data on 34,297 oldest-old individuals from the seven waves of the Chinese Longitudinal Healthy Longevity Study. We estimated age, period, and cohort effects on the prevalence of self-reported ADL impairment, tested physical performance and cognitive function impairment using the age-period-cohort model. Regarding age, the prevalence of ADL, physical performance, and cognitive function impairment were highest in the centenarians, but they did not increase with age in this population. Among the literate subgroup, the prevalence of cognitive impairment increased more rapidly with age than that in the illiterate subgroup. Regarding period, the prevalence of self-reported and tested physical impairment slowly increased between 1998 and 2014, but cognitive impairment remained stable. Regarding cohort, ADL impairment continuously decreased. However, physical and cognitive impairment remained stable after a brief decline in the early birth cohorts. The results suggest that the age effect is still the most obvious effect regarding several types of functional impairment. The likelihood of a younger person experiencing functional impairment may not change significantly, but ADL is likely to be amenable to improvement resulting from improved medical and social care. Therefore, increased care for the oldest-old may considerably improve their quality of life, particularly regarding their basic ADL.

Quality-adjusted life years (QALYs) associated with limitations in activities of daily living (ADL) in a large longitudinal sample of the U.S. community-dwelling older population

BackgroundThe staging method for activities of daily living (ADLs) limitations developed by Stineman and colleagues that classifies people into five stages can reflect severity of activity limitations. ObjectiveTo assess the impact of stages of limitations in ADLs on quality-adjusted life years (QALYs) and the relative severity of each ADL limitation for a large, nationally-representative sample of the U.S. community-dwelling older population. MethodsData were obtained from the Limited Dataset of the Medicare Health Outcomes Survey Cohort 15 (2012 baseline survey, 2014 follow-up survey). We included respondents aged ≥65 years (n = 105,473). We estimated expected QALYs throughout the remaining lifetime of participants stratified by the ADL limitation status and stages of ADL limitations. ResultsOverall, the expected QALYs was 5.6 years. QALYs decreased with increasing stages of ADL limitations. The adjusted QALYs for Stage 0 (no limitation) participants were 6.8; for Stage I (mild) participants, 3.9; for Stage II (moderate) participants, 2.2; for Stage III (severe) participants, 1.8; and for Stage IV (complete limitations) participants, 1.5. Differences in QALYs occurred between individual ADL items within an ADL stage. In Stage I, for example, participants who reported only problems with getting in or out of chairs had 6.7 QALYs which was markedly higher than participants who reported only problems with walking (3.8 QALYs). ConclusionsOur findings provide additional evidence that Stineman's ADL stages serve as valid estimates of the overall health of elderly Americans. Self-reported ADL status should be routinely collected as a patient-reported outcome in the elderly population.

Association Between Executive Dysfunction and Instrumental Activities of Daily Living: Racial and Ethnic Differences Among Community-Dwelling Older Adults in the Southeastern US.

ObjectiveExamining cultural differences in assessment of cognitive/functional disability among older Americans is needed. This analysis examined associations between day-to-day function, measured by activities of daily living (ADL), and cognition, measured by CLOX scores, among older African American (AA) and non-Hispanic White (nHW) community-dwelling women and men. Methods: Design- Cross-sectional. SettingHomes of community-dwelling older adults. Participants- 893 Medicare beneficiaries >65 living in west-central Alabama, without diagnoses of dementia, who were participants in the University of Alabama at Birmingham (UAB) Study of Aging, and who had complete data. Measurements- Physical function was assessed by self-reported ADL difficulty; cognitive function by CLOX, a clock drawing-task. Multivariable, linear regression models were used to examine associations within race/sex specific groups. ResultsAfter controlling for socio-demographic factors and comorbidities, CLOX1 scores were inversely and significantly correlated with ADL for AA men (β = −0.205, P = 0.003). CLOX2 scores were similarly associated with ADL and IADL for the total group (β = −0.118, P = 0.001, and β = −0.180, P < 0.001, respectively); for ADL, significant associations were seen for AA men and nHW women (β = −0.203, P = 0.004, and β = −0.139, P = 0.02, respectively) and, for IADL, in AA women and men (β = −0.156, P = 0.03, and β = −0.24, P < 0.001, respectively). ConclusionWhile African American women reported the highest difficulty with ADLs and IADLs among all race/sex groups, CLOX1 scores were correlated with ADL for AA men only. CLOX1 may have limitations to identify functional disability for older AA women. [Word Count = 234].
