The association between motor capacity and mobility performance: frailty as a moderator

Abstract Background In older adults, the linkage between laboratory-assessed ‘motor capacity’ and ‘mobility performance’ during daily routine is controversial. Understanding factors moderating this relationship could help developing more valid assessment as well as intervention approaches. We investigated whether the association between capacity and performance becomes evident with transition into frailty, that is, whether frailty status moderates their association. Methods We conducted a cross-sectional analysis of the observational Arizona Frailty Cohort Study (ClinicalTrials.gov identifier: NCT01880229) in a community-dwelling cohort in Tucson, Arizona. Participants were N = 112 older adults aged 65 years or older who were categorized as non-frail (n = 40), pre-frail (n = 53) or frail (n = 19) based on the Fried frailty index. Motor capacity was quantified as normal (NWS) and fast walking speed (FWS). Mobility performance was quantified as 1) cumulated physical activity (PA) time and 2) everyday walking performance (average steps per walking bout; maximal number of steps in one walking bout), measured by a motion sensor over a 48 h period. Hierarchical linear regression analyses were performed to evaluate moderation effects. Results Unlike in non-frail persons, the relationship between motor capacity and mobility performance was evident in pre-frail and frail persons, confirming our hypothesis. A moderating effect of frailty status was found for 1) the relationship between both NWS and FWS and maximal number of steps in one bout and 2) NWS and the average steps per bout. No moderation was found for the association between NWS and FWS with cumulated PA. Conclusion In pre-frail and frail persons, motor capacity is associated with everyday walking performance, indicating that functional capacity seems to better represent mobility performance in this impaired population. The limited relationship found in non-frail persons suggests that other factors account for their mobility performance. Our findings may help to inform tailored assessment approaches and interventions taking into consideration a person’s frailty status.

Frailty Status

Abstract Background Frailty is defined as a state of vulnerability to stressors that is associated with higher morbidity, mortality and healthcare utilization in older adults. Ageism is “a process of systematic stereotyping and discrimination against people because they are old.” Explicit biases involve deliberate or conscious controls, while implicit bias involve unconscious processes. Multiple studies show that self-directed ageism is a risk factor for increased morbidity and mortality. The purpose of this study was to determine whether explicit ageist attitudes are associated with frailty in Veterans. Methods This is a cross-sectional study of Veterans 50 years and older who completed the Kogan’s Attitudes towards Older People Scale (KAOP) scale to assess explicit ageist attitudes and the Implicit Association Test (IAT) to evaluate implicit ageist attitudes from July 2014 through April 2015. We constructed a frailty index (FI) of 44 variables (demographics, comorbidities, number of medications, laboratory tests, and activities of daily living) that was retrospectively applied to the time of completion of the KAOP and IAT. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by multinomial logistic regression models with frailty status (robust, prefrail and frail) as the outcome variable, and with KAOP and IAT scores as the independent variables. Age, race, ethnicity, median household income and comorbidities were considered as covariates. Results Patients were 89.76% male, 48.03% White, 87.93% non-Hispanic and the mean age was 60.51 (SD = 7.16) years. The proportion of robust, pre-frail and frail patients was 11.02% (n = 42), 59.58% (n = 227) and 29.40% (n = 112) respectively. The KAOP was completed by 381 and the IAT by 339 participants. In multinomial logistic regression, neither explicit ageist attitudes (KAOP scale score) nor implicit ageist attitudes (IAT) were associated with frailty in community dwelling Veterans after adjusting for covariates: OR = .98 (95% CI = .95–1.01), p = .221, and OR:=.97 (95% CI = .37–2.53), p = .950 respectively. Conclusions This study shows that neither explicit nor implicit ageist attitudes were associated with frailty in community dwelling Veterans. Further longitudinal and larger studies with more diverse samples and measured with other ageism scales should evaluate the independent contribution of ageist attitudes to frailty in older adults.

Abstract Background We sought to determine whether cortical and regional β-amyloid (Aβ) were cross-sectionally and prospectively associated with change in frailty status in older adults. Methods We used data from 269 community-dwelling participants from the Multidomain Alzheimer’s Preventive Trial (MAPT) who were assessed for brain Aβ using positron-emission tomography scan. Regional and cortical-to-cerebellar standardized uptake value ratios were obtained. Frailty was assessed by a frailty index composed of 19 items not directly linked to cognition and Alzheimer’s disease. Results A significant and positive cross-sectional and prospective relationship was found for Aβ in the anterior putamen (cross-sectional: β = 0.11 [0.02–0.20], p = .02; prospective: β = 0.11 [0.03–0.19], p = .007), posterior putamen (cross-sectional: β = 0.12 [0.009–0.23], p = .03; prospective: β = 0.11 [0.02–0.21], p = .02), and precuneus regions (cross-sectional: β = 0.07 [0.01–0.12], p = .01; prospective: β = 0.07 [0.01–0.12], p = .01) with increasing frailty. Conclusions This study has found new information regarding cross-sectional and prospective positive associations between region-specific brain Aβ deposits and worsening frailty. The potential mechanisms involved require further investigation.

Sectional Analysis

Neighborhood physical characteristics have been consistently associated with the health of older adults. This article investigates links between frailty and perceptions of the neighborhood environment. Using a cross-sectional analysis of 370 community-dwelling older adults from Nagoya, Japan, neighborhood perceptions were assessed using the Neighborhood Environmental Walkability Scale (NEWS) in addition to frailty, using a frailty index. Frailty was associated with the NEWS composite index, land use mix diversity, land use mix access, street connectivity, walking infrastructure, aesthetics, and crime safety, after adjustment for covariates. Older adults with increasing frailty have poorer perceptions of their neighborhoods, which could lead to further constriction of the life-space, less social and physical engagement, and worsening of frailty status.

Background: Inflammation has been reported to play an important role in frailty syndrome. The neutrophil–lymphocyte ratio (NLR) has recently emerged as an informative marker for systematic inflammation. However, few studies have examined the association between NLR and frailty. This study aims to examine the association between NLR and frailty in community-dwelling older adults.Methods: Community-dwelling older adults aged ≥ 65 years in the 2011 (n = 2,354) and 2014 (n = 2,458) waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) were included. Frailty status was determined using the 38-item frailty index (FI) and categorized into “robust” (FI ≤ 0.1), “pre-frail” (0.1 < FI ≤ 0.21), or “frail” (FI > 0.21). NLR was calculated using a derived formula: NLR = (white blood cell–lymphocyte)/lymphocyte.Results: A total of 3,267 participants were finally included. In cross-sectional analyses, participants with higher NLR levels had increased likelihood of frailty [the 3rd quartile: adjusted odds ratio (OR) = 1.29; 95% confidence interval (CI): 1.02–1.63; the 4th quartile: OR = 1.59; 95% CI: 1.23–2.02) compared with those in the 1st quartile group. During the 3-year follow-up, 164 of the 1,206 participants, robust or pre-frail at baseline, developed frailty, and 197 of the 562 participants, robust at baseline, developed pre-frailty or frailty. Among the robust and pre-frail participants in 2011, after multivariate adjustment, those in the 4th quartile group had a higher frailty incidence than those in the 1st quartile group (OR = 2.06; 95% CI: 1.18–3.59). Among the robust participants in 2011, those in the 4th quartile group also had a higher pre-frailty or frailty incidence than those in the 1st quartile group (OR = 1.95; 95% CI: 1.07–3.55).Conclusion: Among community-dwelling older adults, higher NLR levels were found to be associated with increased odds of prevalent and incident frailty.

The Relationship

Oral hypofunction, resulting from a combined decrease in multiple oral functions, may affect systemic-condition deterioration; however, few studies have examined the association between oral hypofunction and general health among older adults. In this cross-sectional study, we examined the relationship between oral hypofunction and sarcopenia in community-dwelling older adults. We included 878 adults (268 men and 610 women, mean age 76.5 ± 8.3 years). Tongue coating index, oral moisture, occlusal force, oral diadochokinesis (/pa/,/ta/,/ka/), tongue pressure, mas-ticatory function, and swallowing function were evaluated as indicators of oral hypofunction. Grip strength, gait speed, and skeletal muscle mass index were measured as diagnostic sarcopenia parameters. The association between oral hypofunction and sarcopenia was examined via logistic regression using sarcopenia as the dependent variable. Oral hypofunction prevalence was 50.5% overall, 40.3% in men, and 54.9% in women. The prevalence of sarcopenia was 18.6% overall, 9.7% in men, and 22.5% in women. A logistic regression showed oral hypofunction, age, body mass index, higher-level functional capacity, and serum albumin level were significantly associated with sarcopenia. Sarcopenia occurred at an increased frequency in patients diagnosed with oral hypofunction (odds ratio: 1.59, 95% confidence interval: 1.02–2.47); accordingly, oral hypofunction appears to be significantly associated with sarcopenia.

Abstract Objective The present study aimed to examine the prospective associations of physical frailty with future falls and fear of falling (FOF) among community-dwelling older adults. Methods A prospective cohort study with a 48-month follow-up was conducted in a Japanese community. Participants were 2469 community-dwelling older adults aged 65 years or older who completed baseline and follow-up assessments at intervals of 48±2 months. Primary outcomes were recent falls (defined as at least one fall within the past year) and FOF (determined by response to “Are you afraid of falling?”) at follow-up survey. Physical frailty, operationalized by the frailty phenotype (slowness, weakness, exhaustion, weight loss, and low activity) based on the criteria of the Japanese version of the Cardiovascular Health Study (J-CHS), was also assessed as a predictor of future falls and FOF. Results Multivariate logistic regression showed that pre-frailty or frailty increase the risk of not only future falls (OR: 1.57; 95%CI = 1.20-2.05) but also FOF (OR: 1.33; 95%CI = 1.05-1.69). In addition, the relationship between baseline frailty status and future falls remained significant after adjusting for baseline FOF (OR: 1.55; 95%CI = 1.19-2.02), and the relationship between baseline frailty status and future FOF also remained significant after adjusting for baseline falls (OR: 1.32; 95%CI = 1.04-1.68). Conclusions Frailty status may predict future falls and FOF among community-dwelling older adults. Strategies to prevent frailty may be beneficial to prevent not only future falls but also future FOF in a community setting. Impact Falls and FOF have a close relationship but a different clinical meaning. Older adults with physical frailty may require monitoring as high-risk not only for falls but also for FOF.

Aortic Stiffening

Introduction: Frailty is predictive of cardiovascular disease and is suggested to co-occur with arterial stiffening, the hallmark of vascular aging. However, the temporal relationship is uncertain. Using the ARIC study, we examine the association of baseline frailty with cross-sectional and 5-year change in carotid-femoral pulse wave velocity (cfPWV) in older adults. Methods: Participants at visit 5 (2011-2013) were classified as frail (≥3 criteria), prefrail (1-2 criteria), or robust using the Fried frailty phenotype criteria (unintentional weight loss, exhaustion, grip strength, slow walking speed, and low physical activity). We measured cfPWV at visits 5 and 6/7 (2016-2019). We used linear regression with inverse-probability of attrition weights to estimate the association between frailty and 5-year change in cfPWV while accounting for loss-to-follow-up among survivors. Models were adjusted for age, sex, race-center, mean arterial pressure, height, heart rate, smoking, and time between visits. Results: Of 5,096 participants at visit 5 (58% female, 21% black, mean age 75 [SD 5.1] years), 296 (6%) were frail and 2403 (47%) prefrail. In adjusted analyses at visit 5, frail participants had 30 cm/s (95% CI: -9, 69; p=0.1) higher cfPWV and prefrail participants had 12 cm/s (95% CI: -5, 30; p=0.2) higher cfPWV than those classified as robust (Table 1). In longitudinal analyses adjusted for attrition, we observed a 3 cm/s (95% CI: -11, 19; p=0.6) and 6 cm/s (95% CI: 0, 12; p=0.05) greater annualized increase in cfPWV over ~5 years among frail and prefrail participants, respectively, relative to the rate of arterial stiffening among robust participants (26 cm/s per year). Conclusions: Compared to robust older adults, greater aortic stiffness was observed among frail community-dwelling adults. Changes in aortic stiffening over the course of 5 years were not materially influenced by frailty status at baseline. Frail older adults may present with greater arterial aging and its associated hemodynamic effects on target organs.

Objective: To identify the relationship between religiosity and self-rated health among older adults in Colombia. Methods: Data are drawn from the SABE (Salud, Bienestar y Envejecimiento) Colombia Study, a cross-sectional survey conducted in 2015 involving 18,871 community-dwelling adults aged 60 years and older living in urban and rural areas of Colombia. Religiosity was assessed by self-rated religiosity (how religious are you: not at all, somewhat or very). Self-rated health during previous 30 days was assessed as very good, good, fair, poor or very poor, analyzed as an ordinal variable(1-5) using weighted logistic regression, adjusting for confounders. Results: Those who were more religious were older, female, had lower socioeconomic status, and were more likely to be married. Multivariate analyses demonstrated that older adults who were more religious had better self-rated health (OR 0.92 95% CI 0.86- 0.99, p= 0.038); however, there was a significant interaction effect between gender and religiosity on self-rated health (p= 0.002), such that the relationship between religiosity and health was stronger in men (OR 0.86, 95% CI: 0.79-0.94, p= 0.001) but not significant in women. Conclusion: Older adults in Colombia who consider themselves more religious, especially men, are less likely to perceive their physical health as poor compared to those who are less religious.

The Relationship

In older adults, the relationship between healthy eating motivation (HEM) and protein intake as key component of a healthy diet is poorly understood. Therefore, we investigate the association of HEM with (1) total protein intake and (2) intake of different protein sources in older adults with varying functional status. In this cross-sectional study including 250 adults (≥70 years), we assessed HEM with “The Eating Motivation Survey” and protein intake by 7-day food records. In addition, gender, age, Body Mass Index (BMI), energy intake and functional status were considered. Regression analyses revealed that HEM was neither related to total (β = −0.02; p = 0.723) nor to relative protein intake (β = 0.04; p = 0.370). Notwithstanding this, participants with stronger HEM showed lower intake of protein from meat and meat products (β = −0.14; p = 0.018), higher intake of overall plant-based protein (β = 0.11; p = 0.032), protein from fruit and vegetables (β = 0.20; p = 0.002) and from pulses, nuts an seeds (β = 0.16; p = 0.016). Our findings suggest HEM as a valuable indicator for intake of distinct protein sources. However, since HEM is not related to total protein intake, the importance of sufficient protein consumption should be emphasized by promoting healthy eating, regardless of self-perceived HEM.

Abstract Introduction The presence of either frailty or cognitive impairment have been determined as precursors of falls among older adults. However, the association between falls and cognitive frailty has yet to be established. Objective To investigate the association between falls and cognitive frailty among community dwelling older adults. Methods A total of 246 Malaysian community dwelling older adults aged 60 years and above residing in the state of Selangor participated in this cross-sectional study. Sociodemographic details and clinical characteristics including the history of falls were obtained via interview. The presence of cognitive frailty was identified using the Clinical Dementia Rating Scale and Fried Frailty Index. Data analysis was carried out via binary logistic regression. Results The prevalence of falls and cognitive frailty in this study were 21.2% and 21.9% respectively among community dwelling older adults (mean age 72.39±5.40). No significant relationship between falls and cognitive frailty [OR:1.187, 95% C.I: 0.493-2.856, p=0.702] was demonstrated. However, older women [OR:2.663, 95% C.I, 1.136-6.239, p=0.024] and the presence of multi-morbidities [OR: 1.431, 95% C.I, 1.026-1.997, p=0.035] were significantly associated with falls which corroborates with existing literature. Conclusion Cognitive frailty was not a significant risk factor of falls among community dwelling older adults in this study. Further research is required in prospective, longitudinal, population-based studies to confirm this result.
