Are immigrant enclaves healthy places to live? The Multi-ethnic Study of Atherosclerosis

The growing size and changing composition of the foreign-born population in the USA highlights the importance of examining the health consequences of living in neighborhoods with higher proportions of immigrants. Using data from the Multi-ethnic Study of Atherosclerosis in four US cities, we examined whether neighborhood immigrant composition was associated with health behaviors (diet, physical activity) among Hispanic and Chinese Americans (n = 1902). Secondarily we tested whether neighborhoods with high proportions of immigrants exhibited better or worse neighborhood quality, and whether these dimensions of neighborhood quality were associated with healthy behaviors. Neighborhood immigrant composition was defined based on the Census 2000 tract percent of foreign-born from Latin-America, and separately, percent foreign-born from China. After adjustment for age, gender, income, education, neighborhood poverty, and acculturation, living in a tract with a higher proportion of immigrants was associated with lower consumption of high-fat foods among Hispanics and Chinese, but with being less physically active among Hispanics. Residents in neighborhoods with higher proportions of immigrants reported better healthy food availability, but also worse walkability, fewer recreational exercise resources, worse safety, lower social cohesion, and lower neighborhood-based civic engagement. Associations of neighborhood immigrant composition with diet persisted after adjustment for reported neighborhood characteristics, and associations with physical activity were attenuated. Respondent-reported neighborhood healthy food availability, walkability, availability of exercise facilities and civic participation remained associated with behaviors after adjusting for immigrant composition and other covariates. Results show that living in an immigrant enclave is not monolithically beneficial and may have different associations with different health behaviors.     

Risk of type 2 diabetes mellitus among adults aging with vision impairment: The role of the neighborhood environment

BackgroundVision impairment (VI) affects approximately 1 in 28 Americans over the age of 40 and the prevalence increases sharply with age. However, experiencing vision loss with aging can be very different from aging with VI acquired earlier in life. People aging with VI may be at increased risk for diabetes due to environmental barriers in accessing health care, healthy food, and recreational resources that can facilitate positive health behaviors.ObjectiveThis study examined the relationship between neighborhood characteristics and incident type 2 diabetes mellitus (T2DM) among a cohort of 22,719 adults aging with VI.MethodsData are from Optum® Clinformatics® DataMart, a private administrative claims database (2008–2017). Individuals 18 years of age and older at the time of their initial VI diagnosis were eligible for analysis. VI was determined using vision impairment, low vision, and blindness codes (ICD-9-CM, ICD-10-CM). Covariates included age, sex, and comorbidities. Cox models estimated adjusted hazard ratios (HRs) for incident T2DM. Stratified models examined differences in those aging with (age 18–64) and aging into (age 65+) vision impairment.ResultsResidence in neighborhoods with greater intersection density (HR = 1.26) and high-speed roads (HR = 1.22) were associated with increased risk of T2DM among older adults with VI. Living in neighborhoods with broadband internet access (HR = 0.67), optical stores (HR = 0.62), supermarkets (HR = 0.78), and gyms/fitness centers (HR = 0.63) was associated with reduced risk of T2DM for both younger and older adults with VI.ConclusionsFindings emphasize the importance of neighborhood context for mitigating the adverse consequences of vision loss for health.     

Do neighborhood characteristics of sober living houses impact recovery outcomes? A multilevel analysis of observational data from Los Angeles County

ObjectiveTo identify neighborhood factors associated with recovery outcomes for sober living house (SLH) residents.MethodsSix-month longitudinal data for new SLH residents (n = 557) was linked with census tract data, services available, alcohol outlets, and Walk Scores® (0–100 score indicating access to neighborhood resources) for 48 SLHs in 44 neighborhoods in Los Angeles County.ResultsNon-significant neighborhood characteristics in separate regressions for all outcomes were residents' ratings of perceived risk, percentage of residences with access to a car, percentage of homes over $500,000, percentage of renter-occupied units, percentage with income less than $25,000, percentage that were non-white, the density of substance inpatient within 10 miles, and transit scores from Walk Score®. Multilevel regressions found outpatient substance abuse treatment and density of AA groups were positively associated with more abstinent days. No neighborhood variables were associated with psychiatric symptoms. Higher perceived neighborhood cohesion, lower crime ratings, and better transportation ratings were associated with higher recovery capital.ConclusionGreater neighborhood densities of substance abuse services and AA groups may help residents achieve more days abstinent. While residents may achieve better substance use outcomes even with negative perceptions of the neighborhood, positive perceptions of the neighborhoods may help them acquire more recovery capital.     

Neighborhood environment and cognitive function in older adults: A multilevel analysis in Hong Kong

In considering the influence of the neighborhood environment on cognitive function, little research has looked beyond the individual factors. Here, we conducted a study on 21,008 older adults aged 65 years and above in Hong Kong to examine the cross-sectional associations of neighborhood economic disadvantage, recreational resources, walkability, library accessibility and physical activities on cognitive function and dementia. Both smaller and larger census tracts were adopted as proxies for neighborhoods. Using multilevel regression, neighborhood economic disadvantage was found to be associated with cognitive decline, net of individual features. This association was not explained by neighborhood built environment. Recreational environment was not a significant factor for older adults' cognitive function while library accessibility was. Neighborhood walkability was only related to dementia but not the cognitive function score. Physical activity can partly explain the relationship between neighborhood environment and cognitive function. No significant interaction effect was identified except on the educational level and neighborhood library accessibility. To conclude, late life residential environments are important contexts for aging. Aging-in-place interventions in Hong Kong should thus address neighborhood poverty, improve accessibility of libraries and walkability to reduce future risks of cognitive decline.     

中国50岁及以上人群衰弱轨迹的研究

目的 识别中国≥50岁人群的衰弱轨迹，并探索相关影响因素。方法 采用WHO“全球老龄化与成人健康研究”（SAGE）中国项目第一至第三轮纵向数据，由32种变量计算衰弱指数得分，并在此基础上在组基轨迹模型中采用删失正态模型确定随时间变化的衰弱轨迹模式，采用多项式logistic回归模型研究社会经济地位和行为影响因素对衰弱轨迹的影响。结果 共纳入4 303名≥50岁且拥有3轮完整数据的调查对象进入分析，本研究识别出3条衰弱轨迹：低水平稳定轨迹（LT）、中度增加轨迹（MT）和高度增加轨迹（HT），分别占所有调查对象的75.9%，19.1%和5.0%。多项式logistic回归分析的结果显示，与LT组相比，HT组更倾向是女性（OR=1.88，95%CI：1.22~2.92）和农村居民（OR=1.87，95%CI：1.29~2.70）。在家庭人均财富方面，OR值有一个明显的梯度，较低的家庭财富更有可能归为HT组。结论 本研究识别出了3种我国≥50岁人群衰弱轨迹的进展模式，并强调了干预措施应尽可能地以那些衰弱进展快速的脆弱人群为目标。     

Neighborhood socioeconomic deprivation,perceived neighborhood factors,and cortisol responses to induced stress among healthy adults

Associations between measures of neighborhood socioeconomic deprivation and health have been identified, yet work is needed to uncover explanatory mechanisms. One hypothesized pathway is through stress, yet the few studies that have evaluated associations between characteristics of deprived neighborhoods and biomarkers of stress are mixed. This study evaluated whether objectively measured neighborhood socioeconomic deprivation and individual perceived neighborhood characteristics (i.e. social control and fear of crime) impacted cortisol responses to an induced stressor among older healthy adults. Data from Heart Scan, a sub-study of the Whitehall II cohort, were used to generate multilevel piecewise growth-curve models of cortisol trajectories after a laboratory stressor accounting for neighborhood and demographic characteristics. Neighborhood socioeconomic deprivation was significantly associated with individual perceptions of social control and fear of crime in the neighborhood while an association with blunted cortisol reactivity was only evidence among women. Social control was significantly associated with greater cortisol reactivity and mediation between neighborhood socioeconomic deprivation and cortisol reactivity was suggested among women. These findings support a gender-dependent role of neighborhood in stress process models of health.     

Quantile Regression Forests to Identify Determinants of Neighborhood Stroke Prevalence in 500 Cities in the USA: Implications for Neighborhoods with High Prevalence

Stroke exerts a massive burden on the US health and economy. Place-based evidence is increasingly recognized as a critical part of stroke management, but identifying the key determinants of neighborhood stroke prevalence and the underlying effect mechanisms is a topic that has been treated sparingly in the literature. We aim to fill in the research gaps with a study focusing on urban health. We develop and apply analytical approaches to address two challenges. First, domain expertise on drivers of neighborhood-level stroke outcomes is limited. Second, commonly used linear regression methods may provide incomplete and biased conclusions. We created a new neighborhood health data set at census tract level by pooling information from multiple sources. We developed and applied a machine learning–based quantile regression method to uncover crucial neighborhood characteristics for neighborhood stroke outcomes among vulnerable neighborhoods burdened with high prevalence of stroke. Neighborhoods with a larger share of non-Hispanic blacks, older adults, or people with insufficient sleep tended to have a higher prevalence of stroke, whereas neighborhoods with a higher socio-economic status in terms of income and education had a lower prevalence of stroke. The effects of five major determinants varied geographically and were significantly stronger among neighborhoods with high prevalence of stroke. Highly flexible machine learning identifies true drivers of neighborhood cardiovascular health outcomes from wide-ranging information in an agnostic and reproducible way. The identified major determinants and the effect mechanisms can provide important avenues for prioritizing and allocating resources to develop optimal community-level interventions for stroke prevention.     

Longitudinal profiles of neighborhood socioeconomic vulnerability influence blood pressure changes across the female midlife period

PurposeTo examine whether longitudinal exposure to neighborhood socioeconomic vulnerability influences blood pressure changes throughout midlife in a racially, ethnically, and geographically-diverse cohort of women transitioning through menopause.MethodsWe used longitudinal data on 2738 women (age 42–52 at baseline) living in six United States cities from The Study of Women's Health Across the Nation. Residential histories, systolic blood pressures (SBP), and diastolic blood pressures (DBP) were collected annually for ten years. We used longitudinal latent profile analysis to identify patterns of neighborhood socioeconomic vulnerability occurring from 1996 to 2007 in participant neighborhoods. We used linear mixed-effect models to determine if a woman's neighborhood profile throughout midlife was associated with blood pressure changes.ResultsWe identified four unique profiles of neighborhood socioeconomic vulnerability – differentiated by residential socioeconomic status, population density, and vacant housing conditions – which remained stable across time. Women residing in the most socioeconomically vulnerable neighborhoods experienced the steepest increase in annual SBP growth by 0.93 mmHg/year (95% CI: 0.65–1.21) across ten-year follow-up.ConclusionsNeighborhood socioeconomic vulnerability was significantly associated with accelerated SBP increases throughout midlife among women.     

50岁及以上人群每日静坐时间与衰弱的关联研究

目的 分析≥50岁人群中每日静坐时间与衰弱发生的关系。方法 利用WHO全球老龄化与成人健康研究中国项目第一轮基线调查,采用两水平（个体层面和社区层面）logistic回归模型按城乡进行分层分析每日静坐时间与衰弱的关系,并采用限制性立方样条曲线分析两者之间的剂量-反应关系。结果 共纳入13 175名≥50岁中老年人进行分析。城市（OR=1.22,95% CI：1.17～1.27）及农村（OR=1.11,95% CI：1.05 ～1.18）地区人群每日静坐时间与衰弱发生均显著相关。限制性立方样条曲线显示,每日静坐时间与衰弱发生存在近似线性剂量-反应关系。结论 每日静坐时间与衰弱发生显著相关,并呈近似线性关系。     

50岁及以上人群睡眠时间与衰弱的关联研究

目的 了解中老年人群睡眠时间与衰弱之间的关系。方法 利用WHO全球老龄化与成人健康研究中国项目第一轮基线调查，采用健康缺陷累计数与所考虑的40个健康相关变量的比值构建衰弱指数，采用两水平（个体层面和社区层面）logistic回归模型分析自报睡眠时间与衰弱的关系，并对年龄、性别和居住地区进行分层分析。采用限制性立方样条曲线绘制自报睡眠时间与衰弱关系的剂量-反应曲线。结果 共纳入13 175名≥50岁中老年人，在未调整任何混杂因素的情况下，相比正常睡眠时间，睡眠时间较短或者较长均显著增大衰弱发生风险（OR=2.05，95% CI：1.71～2.44；OR=1.35，95% CI：1.12～1.63），在调整了性别、年龄、居住地区、文化程度、家庭经济水平、水果蔬菜摄入状况、吸烟、饮酒和体力活动后，相比正常睡眠时间，只有睡眠时间较短与衰弱发生风险显著正相关（aOR=1.60，95% CI：1.27～2.01）。对性别、年龄和居住地区进行分层分析，结果显示，调整了性别、年龄、居住地区、文化程度、家庭经济水平、水果蔬菜摄入状况、吸烟、饮酒和体力活动后，相比正常睡眠时间，只有睡眠时间较短与衰弱发生风险显著正相关。此外，在≥65岁人群中，调整相关混杂因素后，相比正常睡眠时间，睡眠时间较短人群衰弱的发生风险增加91%（aOR=1.91，95% CI：1.46～2.49）。平均睡眠时间与衰弱发生呈近似“U”形关系。结论 睡眠时间较短可能与衰弱发生有关。     

Combined measure of neighborhood food and physical activity environments and weight-related outcomes: The CARDIA study

Engagement in healthy lifestyle behaviors likely reflects access to a diverse and synergistic set of food and physical activity resources, yet most research examines discrete characteristics. We characterized neighborhoods with respect to their composition of features, and quantified associations with diet, physical activity (PA), body mass index (BMI), and insulin resistance (IR) in a longitudinal biracial cohort (n=4143; aged 25–37; 1992–2006). We used latent class analysis to derive population-density-specific (<vs.≥1750 people per sq km) clusters of neighborhood indicators: road connectivity, parks and PA facilities, and food stores/restaurants. In lower population density areas, a latent class with higher food and PA resource diversity (relative to other clusters) was significantly associated with higher diet quality. In higher population density areas, a cluster with relatively more natural food/specialty stores; fewer convenience stores; and more PA resources was associated with higher diet quality. Neighborhood clusters were inconsistently associated with BMI and IR, and not associated with fast food consumption, walking, biking, or running.     

Examine the associations between perceived neighborhood conditions,physical activity,and mental health during the COVID-19 pandemic

This study examined how neighborhood conditions changed and how neighborhood conditions were associated with physical activity and mental health during the COVID-19 pandemic among Americans. The major outcomes were stratified by the neighborhood's poverty and regression models were used to assess the associations between neighborhood conditions and their change during the pandemic and the outcomes of physical activity and mental health. The results show that low-poverty neighborhoods had more health-promoting neighborhood conditions before the outbreak and more positive changes during the outbreak. Health-promoting neighborhood conditions were associated with higher physical activity and moderate physical activity and lack of negative neighborhood conditions such as crime/violence and traffic were associated with a lower risk of mental health problems including loneliness, depression, and anxiety. Mental health problems were also significantly associated with the COVID-19 infection and death and household income level. Our findings suggest that it is plausible that the disparities of physical activity and mental health by neighborhood exacerbate due to the pandemic and people who living in socioeconomically disadvantaged neighborhoods bear increasingly disproportionate burden.     

Prevalence and Incidence of Frailty Among Community-dwelling Older Adults in Slovenia

IntroductionFrailty is recognized as one of the most important global health challenges as the population is aging. The aim of this study was to evaluate prevalence and incidence of frailty, and associated factors, among the population of older adults in Slovenia compared to other European countries.MethodsThe prevalence and 4-year incidence of frailty among older adults (≥65 years) were evaluated using data from the Survey of Health, Ageing and Retirement in Europe (SHARE). Frailty was defined by the SHARE operationalization of Frailty phenotype. Multiple logistic regression model was used to explore factors associated with frailty.ResultsAge-standardized prevalence (95% CI) of frailty and pre-frailty in Slovenia were 14.9% (13.3-16.5) and 42.5% (39.8-45.2), respectively. Factors (OR, 95% CI) associated with increased frailty in Slovenia included age (7584 years: 5.03 (3.08-8.22); ≥85 years 21.7 (10.6-44.7) vs. 65-74 years), self-rated health (fair: 4.58 (2.75-7.61), poor: 54.6 (28.1-105.9) vs. excellent/very good/good), number of chronic diseases (1.20 (1.03-1.40)), and polypharmacy (yes: 3.25 (1.93-5.48) vs. no). Female gender and lower education were significantly associated with pre-frailty, but not frailty, in the adjusted model. Independently of these characteristics, age-standardized prevalence of frailty varied among geographical regions. Age-standardized 4-year incidence of frailty and pre-frailty in Slovenia were 6.6% (3.0-10.1) and 40.2% (32.7-47.6), respectively.ConclusionAmong the Slovenian population of older adults aged 65 years and older, the age-standardized prevalence of frailty is 15% and 4-year incidence of frailty is 7%. Regional differences in Slovenia show the lowest prevalence in central Slovenian regions and the highest in northeastern Slovenian regions.     

Spatial Equity in Facilities Providing Low- or No-Fee Screening Mammography in Chicago Neighborhoods

Recent research suggests living in an economically disadvantaged neighborhood is associated with decreased likelihood of undergoing mammography and increased risk of late-stage breast cancer diagnosis. Long distances and travel times to facilities offering low- or no-fee mammography may be important barriers to adherence to mammography screening recommendations for women living in economically disadvantaged urban neighborhoods, in which African–Americans are disproportionately represented. The purpose of this study was to examine whether the spatial distribution of facilities providing low- or no-fee screening mammography in Chicago, Illinois, is equitable on the basis of neighborhood socioeconomic and racial characteristics. We found that distance and travel times via automobile and public transportation to facilities generally decrease as neighborhood poverty increases. However, we also found that the strength of the association between neighborhood poverty level and two of the spatial accessibility measures—distance and public transportation travel time—is less strong in African–American neighborhoods. Among neighborhoods with the greatest need for facilities (i.e., neighborhoods with the highest proportions of residents in poverty), African–American neighborhoods have longer travel distances and public transportation travel times than neighborhoods with proportionately fewer African–American residents. Thus, it appears that the spatial accessibility of low- and no-fee mammography services is inequitable in Chicago. In view of persistent social disparities in health such as breast cancer outcomes, these findings suggest it is important for researchers to examine the spatial distribution of health resources by both the socioeconomic and racial characteristics of urban neighborhoods.

Is Neighborhood Green Space Associated With Less Frailty? Evidence From the Mr. and Ms. Os (Hong Kong) Study

Objectives

To examine whether neighborhood green space was related to frailty risk longitudinally and to examine the relative contributions of green space, physical activity, and individual health conditions to the frailty transitions.

Perceived and objective neighborhood environment attributes and health related quality of life among the elderly in Bogotá, Colombia

This study examines associations between neighborhood environment attributes and health related quality of life (HRQOL) and self-rated health (SRH) among older adults (60 years and over) in Bogotá, Colombia. Perceived and objective neighborhood environmental characteristics were assessed in a cross sectional multilevel design with 1966 older adults within 50 neighborhoods. Outcome variables included HRQOL (physical and mental dimensions) and SRH measured with the Spanish version of the Short Form 8 (SF-8). Independent variables included perceived and objective neighborhood characteristics as well as self-reported levels of walking. Hierarchical linear and logistic regression models were used for the analysis. Among perceived neighborhood characteristics, safety from traffic was positively associated with both HRQOL dimensions and SRH. Having safe parks was positively associated with the mental dimension of HRQOL and with SRH. Street noise was negatively associated with both HRQOL dimensions. Regarding objective neighborhood characteristics, residing in areas with more than eight percent of land covered by public parks was positively associated with SRH. Objective and perceived neighborhood characteristics could provide insight into potential interventions among older adults from rapidly urbanizing settings in Latin America.     

Disability and the built environment: an investigation of community and neighborhood land uses and participation for physically impaired adults

PurposeThere is a need for empirical support of the association between the built environment and disability-related outcomes. This study explores the associations between community and neighborhood land uses and community participation among adults with acquired physical disability.MethodsCross-sectional data from 508 community-living chronically disabled adults in New Jersey were obtained from among participants in national Spinal Cord Injury Model Systems database. Participants' residential addresses were geocoded to link individual survey data with Geographic Information Systems data on land use and destinations. The influence of residential density, land use mix, destination counts, and open space on four domains of participation were modeled at two geographic scales—the neighborhood (i.e., half mile buffer) and community (i.e., five mile) using multivariate logistic regression. All analyses were adjusted for demographic- and impairment-related differences.ResultsLiving in communities with greater land use mix and more destinations was associated with a decreased likelihood of reporting optimum social and physical activity. Conversely, living in neighborhoods with large portions of open space was positively associated with the likelihood of reporting full physical, occupational, and social participation.ConclusionsThese findings suggest that the overall living conditions of the built environment may be relevant to social inclusion for persons with physical disabilities.     

Neighborhood Environment and Body Mass Index Trajectories From Adolescence to Adulthood

Objectives

To investigate whether neighborhood conditions during adolescence are associated with body mass index (BMI) extending into young adulthood.

Methods

Latent growth curve modeling was used to examine BMI over three waves (1996, 2001, and 2008) of the National Longitudinal Study of Adolescent Health (n = 9,115).

Results

Parental perceptions of neighborhood disorder and neighborhood structural disadvantage were positively associated with BMI at baseline. Although parental perceptions of disorder were not associated with the rate of change in BMI over time, neighborhood structural disadvantage was positively associated with the slope of BMI. Adolescents who lived in more disadvantaged neighborhoods not only had higher BMI at the beginning of the study, but they also gained weight at a faster rate than those who lived in more advantaged neighborhoods at the first wave of data collection. The data also revealed notable gender, racial, and ethnic subgroup variations in the relationship between neighborhood context and BMI.

Conclusion

The neighborhood environment during the critical period of adolescence appears to have a long-term effect on BMI in adulthood. Policy interventions focusing on the neighborhood environment may have far-reaching effects on adult health.     

Long Sleep Duration Is Associated With Higher Mortality in Older People Independent of Frailty: A 5-Year Cohort Study

ObjectivesAlthough general adult population studies show a U-shaped association between sleep duration and mortality, prolonged rather than short sleep duration was more consistently associated with higher mortality in older populations. Failing health or frailty is a possible mechanism. Thus, we examined the relationship among sleep duration, frailty status, and mortality in an elderly cohort.MethodsA total of 3427 community-living adults 65 years or older were examined for general health, mood, subjective sleep measures (insomnia, napping, sleep apnea, nighttime sleep duration, sleep medications), frailty, and 5-year mortality.ResultsAfter 5 years, 12.9% of men and 4.5% of women had died. Mean nighttime sleep duration was 7.3 hours. Proportion of participants who slept 10 or more hours increased with increasing frailty. Age-adjusted hazard ratio (HR) for 5-year mortality of long nighttime sleep (≥10 hours) was 2.10 (95% confidence interval [CI] 1.33–3.33) in men, and 2.70 (95% CI 0.98–7.46) in women. The HR in men was attenuated (HR 1.75; 95% CI 1.09–2.81) after adjustment for frailty and other covariates, whereas that of women strengthened (HR 2.88; 95% CI 1.01–8.18). Mortality increased sharply with nighttime sleep of 10 hours or more. Nighttime sleep of 10 or more hours (HR 1.75, men; HR 2.88, women) and frailty (HR 2.43, men; HR 2.08, P = .08 in women) were independently associated with 5-year mortality after full adjustment for covariates.ConclusionFrailty and long nighttime sleep duration of 10 or more hours were independently associated with 5-year mortality in older adults.     

The Resilience and the Subsequent Hospitalization of Older People with Different Frailty Status: A Prospective Cohort Study

ObjectiveTo evaluate the difference in resilience across frailty status by measuring the impact of unplanned hospitalization across people with different frailty condition on (1) 2-year changes in lean mass, physical performance, and quality of life, and (2) subsequent hospitalization.DesignA prospective cohort study.Setting and ParticipantsThree thousand seventeen older people (73.7 ± 4.9 years) were recruited from the community in Hong Kong.MethodsFrailty status was defined using the Cardiovascular Health Study scale at baseline. Unplanned hospitalization between the 2 visits was obtained from the Hong Kong Hospital Authority. The interaction of frailty and hospitalization status on the 2-year changes in lean mass, physical performance, and quality of life were examined using 2-way analysis of covariance. Risk of subsequent hospitalization was estimated using Poisson regression. The effect of prolonged hospitalization, which was defined as 6 or more total hospitalized days, was also examined.ResultsUpon unplanned hospitalization, frail older people had significantly augmented decline than prefrail and robust people in appendicular skeletal mass (?0.44 ± 0.08 kg), height-adjusted appendicular skeletal mas (?0.13 ± 0.03 kg/m²), 5-time chair-stand (4.79 ± 0.60 s), and mental health (?3.72 ± 0.88). The reduction increased with the length of hospitalization. Unplanned hospitalization conferred an augmented risk of subsequent hospitalization for those who were prefrail and frail (IRR = 1.44, 95% confidence interval = 1.30-1.59 and IRR = 1.69, 95% confidence interval = 1.45-1.97, respectively).Conclusions and ImplicationsThe resilience of older people varies according to their frailty status, and the poor resilience may translate to a higher chance of having subsequent hospitalization for prefrail and frail people. These findings emphasized the importance of having the frailty screening in making posthospitalization plans for older people depending on their frailty status and encouraging prefrail and frail older people to build up their resilience.
