Frequency of Leaving the House and Mortality from Age 70 to 95

Walking trail access, exercise behavior, and going out-of-home among older adults: Examining longitudinal associations and mediators

AIM

Although the presence of a walking trail within a neighborhood would be an important environmental determinant of health behaviors, such as exercise and going out-of-home, their longitudinal associations and mediators are still unconfirmed. This study examined the longitudinal associations of walking trail access with exercise behavior and going out-of-home and mediating roles of awareness and use of walking trails on their associations among older adults.

METHODS

A four-wave questionnaire-based longitudinal survey was conducted among Japanese older adults (Wave 1: baseline; Wave 2: after one year; Wave 3: after three years; and Wave 4: after five years). Each survey measured weekly exercise time and frequency of going out-of-home. Wave 4 survey also measured awareness and use of walking trails. This study calculated distance to nearest walking trail using geographic information systems. This study analyzed the data from all waves (n = 834) for longitudinal associations and the data from Wave 4 (n = 567) for mediated associations.

RESULTS

Latent growth modeling showed insignificant longitudinal associations of walking trail access with weekly exercise time and frequency of going out-of-home. The path analyses showed that a shorter distance to the walking trail was indirectly and significantly associated with longer weekly exercise time (standardized indirect effect=-0.03, p<.001) and a higher weekly frequency of going out-of-home (standardized indirect effect=-0.03, p<.001), mediated by awareness and use of walking trails.

CONCLUSIONS

These findings indicate that the influence of walking trail access on exercise behavior and going out-of-home would be attenuated by awareness and use of walking trails among older adults.

Homebound older adults who live independently in rural Japan: Prevalence and contributing factors during the COVID-19 pandemic

Being homebound is a phenomenon of confining older adults to their homes owing to health, social, and psychological factors. During the COVID-19 pandemic, people were requested to refrain from going out to prevent infection. Consequently, the homebound status of older adults was influenced by social and environmental factors, resulting in an increase in the number of homebound older adults during the pandemic. This study aimed to determine the homebound prevalence and related factors among homebound older adults during the COVID-19 pandemic. In 2021, a cross-sectional study conducted in rural Saitama, Japan, included 1,020 participants aged 65 years and above who did not have long-term care insurance certification and were independent in instrumental activities of daily living. Herein, homebound individuals were defined as those who went out once a week or less. The relationships of homebound status with demographic, health, social, and psychological factors in older adults were examined. The prevalence of homebound independent older adults was estimated as 10.4 % (6.6 % males, 13.8 % females). Homebound status was significantly associated with one or more medical histories (odds ratio [OR] = 1.98, 95 % confidence interval [CI] = 1.00-3.90), no social or family roles (OR = 1.95, 95 % CI = 1.09-3.48), and no hobbies (OR = 1.84, 95 % CI = 1.02-3.34). Establishing social or family roles and promoting participation in hobbies may prevent older adults from being homebound. The social environment, which changed during the pandemic, should be improved to encourage older adults to go out.

Associations between older adults' going-out frequency and land price of neighbourhoods: Potency of land price as an indicator of homebound tendency

The aim of this study is to identify the potency of land price as a general indicator of the homebound tendency of neighbourhoods. For this purpose, we focus on the associations between land price and older adults' going-out frequency, while considering the similarities and differences from factors associated with walkability. The study targets are 19,270 individuals living in the Tokyo metropolitan area who are aged 65 years or older who are not certified as needing public long-term care insurance. This study uses a two-step procedure: a) the land price of each neighbourhood is estimated using rent price data from 2010 to 2019 collected by an official Japanese realtor organization; b) the associations between older adults' goingout frequency, according to the 2016 Japan Gerontological Evaluation Study, and the estimated land price of their neighbourhoods is identified using multilevel analysis. The results indicate that land price has strong negative associations with older adults' going-out frequency. Associations between land price or other walkability-associated factors, such as population density, ratio of commercial area, and proximity to the nearest train station, only appear when these factors and land price are included within the same model. The results suggest that, when inspecting homebound tendency in some neighbourhoods, factors relating to the built environment must be considered alongside land prices. Furthermore, the homebound status of older adults is a pressing challenge, especially in neighbourhoods with high land prices.

Holocaust survivors: Health and longevity 70 years later

BACKGROUND

Holocaust survivors (HS) alive today form a unique and disappearing population, whose exposure to systematic genocide occurred over 70 years ago. Negative health outcomes were widely documented prior to age 70. We examine the hypothesis that the experience of remote trauma continues to negatively affect health, functional status, and survival between the ages of 85-95.

METHODS

The Jerusalem Longitudinal Study (1990-2022) followed a representative sample of Jerusalem residents born 1920-1921, at ages 85, 90 and 95. Home assessment included medical, social, functional, and cognitive status, and mortality data. Subjects were classified: (1) HS-Camp (HS-C): survived slave-labor, concentration, or death camps; (2) HS-Exposed (HS-E): survived Nazi occupation of Europe; (3) Controls: European descent, outside Europe during WWII. We determined Hazards Ratios (HR), adjusting for gender, loneliness, financial difficulty, physical activity, ADL dependence, chronic ischemic heart disease, cancer, cognitive deficits, chronic joint pain, self-rated health.

RESULTS

At ages 85 (n = 496), 90 (n = 524), and 95 (n = 383) the frequency of HS-C versus HS-E versus Controls was 28%/22%/50%, 19%/19%/62%, and 20%/22%/58%, respectively. No consistent significant morbidity differences were observed. Mortality between ages 85-90 and 90-95 years was 34.9% versus 38% versus 32.0%, and 43.4% versus 47.3% versus 43.7%, respectively, with no significant differences in survival rates (log rank p = 0.63, p = 0.81). Five-year mortality adjusted HRs were insignificant for HS-C and HS-E between ages 85-90 (HR 0.87, 95% CI 0.54-1.39; HR 1.14, 95% CI 0.73-1.78) and ages 90-95 (HR 0.72, 95% CI 0.39-1.32; HR 1.38, 95% CI 0.85-2.23).

CONCLUSIONS

Seventy years following their trauma and suffering during the Holocaust, the significant impairments of health, function, morbidity, and mortality which have accompanied survivors throughout their entire adult life, were no longer observed. Indeed, it is likely that survivors living >85 years old represent a uniquely resilient population of people, whose adaptation to adversity has accompanied them throughout their lives.

Elective Foot and Ankle Procedures in the Patients Greater than 65 Years of Age: Worth the Mobility Gains

Chronic, non-traumatic pathologies of the foot and ankle can be mobility-limiting for patients of all ages. The objective of this study was to compare postoperative changes in LifeSpace Mobility Assessment (LSA) scores of adult and elderly patients following elective foot and ankle surgery. A prospective study of 184 patients undergoing elective ankle, hindfoot, and midfoot procedures conducted by one surgeon between 2015 and 2019 was undertaken. Patient-reported LSA scores were collected at preoperative, 6-month, and 12-month follow-up. Patient data was compared using an independent sample t-test for continuous, normally distributed data and a chi-squared or Fischer's exact test for categorical data. Alpha and beta were .05 and .8. Patients were divided based on age. 140 patients were observed in the younger (<65) group, 44 patients were observed in the elderly (≥65) group. The average LSA score of elderly patients at the preoperative visit was 58.3 (SD 38.0) vs 79.3 (SD 38.8) in the younger cohort (P = .041). Both patient cohorts saw decreased mobility at 3-month postoperative visits but surpassed preoperative mobility scores by 6 months and 1 year postop. No difference in average mobility score was observed between young (85.6, SD 36.1) and elderly (90.1, SD 34.3) cohorts at 1-year follow up. Given the increased rates of perioperative comorbidities and the heightened risks of intraoperative complications, physicians may be more inclined to manage elderly patients with longer periods of conservative treatment for similar pathologies. However, these results imply that elderly patients experience similar improvements after surgery to younger cohorts and should not be excluded from surgical consideration. Our results, in tandem with literature showing the deleterious effects of decreased mobility in the elderly, suggest that the discussion to pursue or hold surgical correction of chronic foot and ankle disease in patients over age 65 must consider the mobility benefits of surgery.

Life-space mobility and post-hospitalization outcomes among older Mexican American Medicare beneficiaries

BACKGROUND

Older adults with limited mobility are at an increased risk of adverse health outcomes, an outcome inadequately investigated in older Mexican Americans. We explored whether pre-admission life-space mobility predicts post-hospitalization outcomes among hospitalized Mexican American Medicare beneficiaries.

METHODS

Life-space mobility, using the Life-Space Assessment (LSA), was analyzed using quartiles and 5-point intervals. Using the Hispanic Established Populations for the Epidemiologic Study of the Elderly (HEPESE) Waves 7 and 8 data linked to Medicare claims data, 426 older Mexican Americans with at least 2 months of Medicare coverage who were hospitalized within 2 years of completing the LSA were included. Logistic and Cox Proportional regression analyses estimated the association of pre-admission LSA with post-hospitalization outcomes.

RESULTS

Prior to hospitalization, 85.4% reported limited life-space mobility. Most patients (n = 322, 75.6%) were hospitalized for medical reasons. About 65% were discharged to the community. Pre-admission LSA scores were not associated with community discharge (Odds Ratio [OR] = 1.02, 0.95-1.10). Higher pre-admission LSA scores were associated with 30-day readmission (OR = 1.11, 1.01-1.22). Patients in the highest pre-admission LSA quartile (i.e., greatest life-space mobility) were less likely to die within 2 years after hospital discharge (OR = 0.61, 0.39-0.97) compared to those with lower pre-admission LSA scores.

CONCLUSIONS

Among older Mexican American Medicare beneficiaries, greater pre-admission LSA scores were associated with an increased risk of 30-day readmission and a decreased risk of mortality within 2 years following hospitalization. Future work should further investigate the relationship between LSA and post-hospitalization outcomes in a larger sample of Mexican American older adults.

Hilly environment and frequency of going out-of-home among older adults: Examining moderating effect of driving status

AIM

The health benefits of "going out-of-home" frequently among older adults are well known. A hilly environment would inhibit this habit. This study examined (i) longitudinal associations between a hilly environment and the frequency of going out-of-home, and (ii) the moderating effect of driving status on their association among older adults.

METHODS

This study involved a longitudinal study design. Data on 856 older adults in Nada Ward, Kobe, Japan, was obtained from a three-wave questionnaire survey (Wave 1: December 2017 to January 2018; Wave 2: after 1 year; Wave 3: after 3 years). In each survey, the frequency of going out-of-home time was measured. The average land slope within 500 m network buffers of each participant's home was calculated as the index of the hilly environment. Driving status was also measured.

RESULTS

The latent growth model revealed that while a higher value of average land slope was not significantly associated with changes in the frequency of going out-of-home over time, it was significantly associated with a lower frequency of going out-of-home at the initial level. The interaction term in the latent growth model showed that driving status did not moderate the associations of the average land slope with the initial level of, and changes in, the frequency of going out-of-home.

CONCLUSIONS

Although it remains unclear whether a hilly environment would accelerate a decline in the frequency of going out-of-home over time, this study found that older adults living in a hilly environment were less likely to leave their homes. Geriatr Gerontol Int 2022; ••: ••-••.

Exploring the Multidimensional Participation of Adults Living in the Community in the Chronic Phase following Acquired Brain Injury

This exploratory study aimed to examine multiple aspects of the participation of adults in the chronic phase following acquired brain injury (ABI), considering different disability levels. Our study included 25 adults ≥6 months after ABI (predominantly stroke), living at home, without severe cognitive decline. Primary measures included the Canadian Occupational Performance Measure (subjective participation) and the Mayo-Portland Adaptability Inventory-4 Participation Index (objective participation). The results indicated subjective participation problems in all of the International Classification of Functioning, Disability and Health participation domains. In addition, objective participation was reported as most limited in the areas of leisure and recreational activities, residence, and employment. Both subjective and objective participation profiles varied according to the disability level except for the social and leisure areas, which were found to be similar across all subgroups. However, only partial compatibility was found between the subjective and objective participation aspects. To conclude, our findings indicated that chronic ABI survivors report a variety of subjective and objective participation concerns that varied according to their disability levels. Moreover, the incongruity between the participation aspects suggests that the level of limitation may not necessarily correspond to the importance of a particular participation area. This highlights the need for comprehensive assessments to determine unique individual participation profiles in order to facilitate client-centered interventions supporting the rehabilitation of community-dwelling ABI survivors.

Predictive Factors of Anxiety, Depression, and Health-Related Quality of Life in Community-Dwelling and Institutionalized Elderly during the COVID-19 Pandemic

The COVID-19 health emergency and restrictive measures have increased psychological problems, particularly anxiety and depression, in the general population. However, little is known about mental health conditions and the possible risk and protective factors of specific population groups, such as institutionalized vs. community-dwelling elderly. We investigated the abovementioned aspects in a sample of 65-89-year-old people during the third wave of COVID-19 in Italy. We employed a sociodemographic survey and four questionnaires on health-related quality of life (SF-36), loneliness (UCLA), spirituality (FACIT-Sp), and anxiety/depression (HADS). Our findings suggest that the physical, psychological, and spiritual well-being of the elderly had not been seriously impaired by the events related to the pandemic, although most of the participants reported a worsening of their social life and a moderate/high fear of COVID-19. In regression analyses, these two latter aspects turned out to be predictors of higher anxiety, while spiritual well-being and the possibility to get out of the house/institution emerged as protective factors against anxiety and for preserving quality of life, respectively. Our findings help refine the picture of the condition of the elderly in the aftermath of the pandemic, giving some hints about how to continue supporting their well-being and quality of life.

The Experience of Homebound Older Adults During the COVID-19 Pandemic

BACKGROUND

Homebound older adults have heightened risks for isolation and negative health consequences, but it is unclear how COVID-19 has impacted them. We examine social contact and mood symptoms among previously homebound older adults during the COVID-19 pandemic.

DESIGN/SETTING

Cross-sectional analysis using data from the National Health and Aging Trends Study (NHATS), a nationally-representative longitudinal study of aging in the USA.

PARTICIPANTS

A total of 3,112 community-dwelling older adults in 2019 who completed the COVID-19 survey in the summer/fall of 2020.

MEASUREMENTS

Homebound status was defined via self-report as rarely/never leaving home or leaving the house with difficulty or help in the prior month. We measured limited social contact during COVID-19 (in-person, telephone, video or email contacts

RESULTS

Among homebound older adults, 13.2% experienced limited social contact during COVID-19 vs. 6.5% of the non-homebound. Differences in social contact were greatest for contacts via email/text/social media: 54.9% of the homebound used this

DISCUSSION

Isolation among homebound older adults increased during COVID-19, partially due to differences in technology use. We must ensure that homebound persons have the connection and care they need including new technologies for communication during and beyond COVID-19.

Prospective assessment of dementia on transitions in homeboundness using multistate Markov models

BACKGROUND

One in 20 older adults in the United States is homebound and rarely/never leaves home. Although being homebound decreases the quality of the lived experience of individuals with serious illnesses, little is known about the frequency or likelihood of transitions in or out of homebound status. The objective of this study was to characterize the probability of transitions to and from homebound status among older adults and examine the relationship between dementia status and homebound transitions.

METHODS

Using 2011-2018 data from the National Health and Aging Trends Study (NHATS), a nationally representative longitudinal study of aging in the United States, we identified 6375 community-dwelling Medicare beneficiaries. Homebound status (independent, semi-homebound (leaving home but with difficulty or help), homebound (rarely or never leaving home), nursing home resident, dead) was assessed annually via self-report. Transition probabilities across states were assessed using a multistate Markov model.

RESULTS

Less than half of homebound individuals remain homebound (probability = 41.5% [95% CI: 39.2%, 43.5%]) after 1 year. One out of four dies (24% [22.3%, 26.0%]) and there is a low probability (3.2% [2.5%, 4.1%]) of transition to a nursing home. Dementia status was associated with increased risk of progression from independence to homebound status (HR: 1.83 [1.01, 3.34]). Dementia was consistently associated with increased probabilities of transitions to death including a two-fold increased hazards of progression from homebound to death (HR: 2.18 [1.69, 2.81]). Homebound individuals with dementia have a 34.2% [25.8%, 48.1%] probability of death in 5 years, compared with 17.4% [13.7%, 24.3%] among those without dementia.

DISCUSSION

Dementia is associated with greater risk of transitioning across homebound states. There is a greater need to support home-based care for patients with dementia, especially as the ongoing COVID pandemic has raised concerns about the need to invest in alternative models to nursing home care.

A Performance-Based Teleintervention for Adults in the Chronic Stage after Acquired Brain Injury: An Exploratory Pilot Randomized Controlled Crossover Study

This pilot study aimed to investigate the initial effect of a remotely delivered performance-based client-centered intervention on activity performance and participation among adults in the chronic phase after acquired brain injury (ABI). Sixteen participants living at home with little to no assistance in basic daily activities were allocated into intervention or waitlist control groups. Assessments were conducted at the baseline, after the 3-month intervention/wait period, and at a 3-month follow-up. The primary outcomes were activity performance using the Canadian Occupational Performance Measure (COPM) and the Performance Quality Rating Scale (PQRS) and participation using the Mayo-Portland Adaptability Inventory-4 (MPAI-4). The intervention included weekly videoconferencing sessions using the Cognitive Orientation to Daily Occupational Performance approach (tele-CO-OP). The participants identified five functional goals, of which three were directly addressed. Wilcoxon signed-ranks test results showed no significant improvements in the control group at the end of the 3-month wait period. Pooled data from both groups showed significant improvements in COPM scores for trained and untrained goals following the intervention. Significant improvements were also found in the PQRS and MPAI-4 scores. Improvements were partially maintained at follow-up. Our preliminary results suggest that tele-CO-OP may positively impact the lives of adults after ABI who are coping with long-term disability.

Receipt Of Home-Based Medical Care Among Older Beneficiaries Enrolled In Fee-For-Service Medicare

Millions of older Americans are homebound and may benefit from home-based medical care. We characterized the receipt of this care among community-dwelling, fee-for-service Medicare beneficiaries ages sixty-five and older surveyed in the National Health and Aging Trends Study between 2011 and 2017. Five percent of those surveyed received any home-based medical care between 2011 and 2017 (mean follow-up time per person was 3.4 years), and 75 percent of home-based medical care recipients were homebound. Only 11 percent of the total homebound population (approximately 4.4 million fee-for-service Medicare beneficiaries in 2017) received any home-based medical care between 2011 and 2017. Receipt of home-based medical care was more common among homebound beneficiaries living in metropolitan areas and assisted living facilities, which suggests that geographic factors create operational efficiencies for home-based medical care practices that may improve their financial sustainability within the fee-for-service reimbursement setting. The significant unmet needs of this high-need, high-cost population and the known health and cost benefits of home-based medical care should spur stakeholders to expand the availability of this care.

Optimism and longevity beyond age 85

BACKGROUND

Optimism is associated with health benefits and improved survival among adults aged >65. Whether or not optimism beyond age 85 continues to confer survival benefits is poorly documented. We examine the hypothesis that being optimistic at ages 85 and 90 is associated with improved survival.

METHODS

The Jerusalem Longitudinal Study (1990-2020) assessed comorbidity, depression, cognition, social and functional status, and 5-year mortality among a representative community sample, born 1920-1921, at age 85 (n=1096) and age 90 (n=533). Overall optimism (Op-Total) was measured using a validated 7-item score from the Scale of Subjective Wellbeing for Older Persons. The four questions concerning positive future expectations (Op-Future) and three questions concerning positive experiences (Op-Happy) were also analyzed separately. We determined unadjusted mortality Hazards Ratios, and also adjusted for gender, financial difficulty, marital status, educational status, ADL dependence, physical activity, diabetes mellitus, hypertension, ischemic heart disease, cognitive impairment and depression.

RESULTS

Between ages 85-90 and 90-95 years, 33.2% (364/1096) and 44.3% (236/533) people died respectively. All mean optimism scores declined from age 85 to 90, with males significantly more optimistic than females throughout. All measures of optimism (Op-Total, Op-Future, Op-Happy) at age 85 and 90 were significantly associated with improved 5-year survival from age 85-90 and 90-95 respectively, in both unadjusted and adjusted models. Findings remained unchanged after separately excluding depressed subjects, cognitively impaired subjects, and subjects dying within 6 months from baseline.

CONCLUSIONS

These finding support the hypothesis that being optimistic continues to confer a survival benefit irrespective of advancing age.

Community-Level Sports Group Participation and Health Behaviors Among Older Non-Participants in a Sports Group: A Multilevel Cross-Sectional Study

This study validates the relationship between community-level sports group participation and the frequency of leaving the house and transtheoretical model stages of behavior change for exercise among older individuals who did not participate in a sports group. We used cross-sectional data from the 2016 Japan Gerontological Evaluation Study. The proportion of sports group participants at the community level was calculated using the data from 157,233 older individuals living in 1000 communities. We conducted a multilevel regression analysis to examine the relationship between the proportion of sports group participants and the frequency of leaving the house (1 day/week or less) and the transtheoretical model stages of behavior change for exercise. A statistically significant relationship was observed between a high prevalence of sports group participation and lower risk of homeboundness (odds ratio: 0.94) and high transtheoretical model stages (partial regression coefficient: 0.06) as estimated by 10 percentage points of participation proportion. Older individuals, even those not participating in a sports group, living in a community with a high prevalence of sports group participation are less likely to be homebound; they are highly interested and have numerous opportunities to engage in exercise.

Social relationships and survival in the older adult cohort

Objective:

to verify the influence of social relations on the survival of older adults living in southern Brazil.

Method:

a cohort study (2008 and 2016/17), conducted with 1,593 individuals aged 60 years old or over, in individual interviews. The outcomes of social relations and survival were verified by Multiple Correspondence Analysis, which guided the proposal of an explanatory matrix for social relations, the analysis of survival by Kaplan-Meier, and the multivariate analysis by Cox regression to verify the association between the independent variables.

Results:

follow-up was carried out with 82.5% (n=1,314), with 46.1% being followed up in 2016/17 (n=735) and 579 deaths (36.4%). The older adults who went out of their homes daily had a 39% reduction in mortality, and going to parties kept the protective effect of 17% for survival. The lower risk of death for women is modified when the older adults live in households with two or more people, in this case women have an 89% higher risk of death than men.

Conclusion:

strengthened social relationships play a mediating role in survival. The findings made it possible to verify the importance of going out of the house as a marker of protection for survival.

The Impact of Frailty on the Relationship between Life-Space Mobility and Quality of Life in Older Adults during the COVID-19 Pandemic

BACKGROUND

The COVID-19 pandemic has led to abrupt restrictions of life-space mobility. The impact of shelter-in-place orders on older adults' health and well-being is still unclear.

OBJECTIVE

To investigate the relationship between life-space mobility and quality of life (QoL) in older adults with and without frailty during the COVID-19 pandemic.

DESIGN

Multicenter prospective cohort study based on structured telephone interviews.

SETTING

Four geriatric outpatient clinics in the metropolitan area of Sao Paulo, Brazil.

PARTICIPANTS

557 community-dwelling adults aged 60 years and older.

MEASUREMENTS

The Life-Space Assessment was used to measure community mobility before and during the COVID-19 pandemic, and a previously validated decrease of ≥ 5 points defined restricted life-space mobility. Frailty was assessed through the FRAIL (fatigue, resistance, ambulation, illnesses, and loss of weight) scale. The impact of shelter-in-place orders on QoL was evaluated with the question «How is the COVID-19 pandemic affecting your QoL?», to which participants could respond «not at all», «to some extent», or «to a great extent». We used ordinal logistic regressions to investigate the relationship between restricted life-space mobility and impact on QoL, adjusting our analyses for demographics, frailty, comorbidities, cognition, functionality, loneliness, depression, and anxiety. We explored whether frailty modified the association between life-space mobility and impact on QoL.

RESULTS

Participants were on average 80±8 years old, 65% were women, and 33% were frail. The COVID-19 quarantine led to a restriction of community mobility in 79% of participants and affected the QoL for 77% of participants. We found that restricted life-space mobility was associated with impact on QoL in older adults during the pandemic, although frailty modified the magnitude of the association (P-value for interaction=0.03). Frail participants who experienced restricted life-space mobility had twice the odds of reporting an impact on QoL when compared with non-frail individuals, with respective adjusted odds ratios of 4.20 (95% CI=2.36-7.50) and 2.18 (95% CI=1.33-3.58).

CONCLUSION

Older adults experienced substantial decreases in life-space mobility during the COVID-19 pandemic, and this unexpected change impacted their QoL. Providers should be particularly watchful for the consequences of abrupt life-space restrictions on frail individuals.

Does Oral Hypofunction Promote Social Withdrawal in the Older Adults? A Longitudinal Survey of Elderly Subjects in Rural Japan

It is often assumed that oral hypofunction is associated with social withdrawal in older adults because decreased motor function is related to decreased oral function. However, few studies have examined the relationship between social withdrawal in older adults and oral function. This longitudinal study aimed to clarify the relationship between changes in the level of social withdrawal and oral function in independent older adults. Participants were 427 older adults aged 65 years or older who took part in a self-administered questionnaire from 2016 to 2017 (baseline), and again two years later (follow-up). At baseline, 17 items related to oral function and confounding factors related to withdrawal, physical condition, physical function, and cognitive function were evaluated. A Cox proportional hazard model was used to examine the oral functions that negatively impact social withdrawal. The following factors were significantly associated with the worsening of social withdrawal: the number of remaining teeth, gingival condition, occlusal force, masticatory efficiency, and items related to swallowing and dry mouth. Older adults with cognitive issues who walk slowly and have a weak knee extension muscle were also significantly more likely to have oral frailty. Those who were found to have oral frailty at baseline were 1.8 times more likely to develop withdrawal compared to those with robust oral function. The results indicated that the worsening of withdrawal was associated with oral hypofunction at baseline. Since oral hypofunction was associated with the worsening of social withdrawal in older adults, it is important to maintain older adults' oral function.

The Association Between Income and Incident Homebound Status Among Older Medicare Beneficiaries

IMPORTANCE

A large and growing population of older adults with multimorbidity, cognitive impairment, and functional disability live in the community, but many never or rarely leave their homes. Being homebound is associated with decreased access to medical services, poor health outcomes, and increased mortality. Yet, it is unknown what factors, in particular socioeconomic factors, are associated with new onset of homebound status.

OBJECTIVE

To evaluate the association between income and risk of becoming homebound.

DESIGN

Observational cohort study using 2011 to 2018 data from the National Health and Aging Trends Study, a nationally representative sample of Medicare beneficiaries aged 65 years and older.

SETTING

Population-based study in the United States.

PARTICIPANTS

A total of 7,042 initially nonhomebound community-dwelling older adults.

EXPOSURE

Total annual household income at baseline (in 2011) measured via self-report.

OUTCOME

Annual measure of homebound status, defined as leaving home an average of 1 d/wk or less.

RESULTS

Over 7 years, 15.81% of older adults in the lowest income quartile (≤$15,003) became homebound, compared with only 4.64% of those in the highest income quartile (>$60,000). In a competing risks analysis accounting for risks of death and nursing home admission, and adjusted for clinical and demographic characteristics, those in the lowest income quartile had a substantially higher subhazard of becoming homebound than those in the highest income quartile (1.65; 95% confidence interval = 1.20-2.29). Moreover, we see evidence of a gradient in risk of homebound status by income quartile.

CONCLUSION AND RELEVANCE

Our work demonstrates that financial resources shape the risk of becoming homebound, which is associated with negative health consequences. In the context of existing income disparities, more support is needed to assist older adults with limited financial resources who wish to remain in the community.

Associations of older adults' excursions from home with health-related physical activity and sedentary behavior

BACKGROUND

As people age, they spend more time in and around their domestic environments, within which opportunities for health-enhancing physical activity (PA) may be limited. We examined the associations of frequency of excursions from home with accelerometer-determined PA and the total and prolonged sedentary behavior (SB, sitting for ≥30 min) among community-dwelling older adults.

METHODS

Overall, 434 older adults (men, 57.1 %; age, 70-79 years) wore an accelerometer (HJA-350IT, Omron Healthcare) for 7 days. Time spent in SB, light-intensity PA (LPA), moderate-to-vigorous PA (MVPA), and prolonged SB bout (≥30 min) were calculated. Frequencies of excursions from home were categorized as 0-3, 4-5, and 6-7 days/week. Associations of excursions with PA and SB were tested by analysis of covariance adjusted for sociodemographic characteristics.

RESULTS

Frequencies were 14.3 %, 31.1 %, and 54.6 % for excursions 0-3, 4-5, and 6-7 days/week, respectively. For men, less frequent excursions from home were significantly associated with less MVPA and more total and prolonged SB times (estimated means [minutes/day]: MVPA, 32, 42, and 48; total SB, 589, 549, and 539; prolonged SB, 344, 288, and 265; respectively; p < 0.05). LPA was not statistically significant (p = 0.09). For women, less frequent excursions were significantly associated with all PA outcomes (SB: 536, 497, and 467; prolonged SB: 260, 213, and 204; LPA: 328, 363, and 379; MVPA: 36, 39, and 54, respectively).

CONCLUSIONS

Among community-dwelling Japanese older adults, more frequent excursions from home were associated with more PA, less SB, and more-favorable SB patterns, suggesting a potential strategy for preventive-health initiatives.
