The Role of Neighborhood Safety in Recovery from Mobility Limitations: Findings from a National Sample of Older Americans (1996-2008)

Psychometric properties of the Feeling of Unsafety Scale-Arabic in general population adults

Background

Feelings of unsafety, including fear of crime, uncertainty, or insecurity, can negatively impact individuals by reducing psychological well-being and worsening health. Validating a simple and cost-effective tool to assess the general feeling of unsafety in the Arabic-speaking population, primarily residing in the Middle-East and North-Africa (MENA) region where safety can be a major concern, would be highly beneficial. The study aimed to translate the Feeling of Unsafety Scale into Arabic (FUSA) and evaluate its psychometric properties, including internal reliability, sex invariance, composite reliability, and correlation with a measure of intolerance of uncertainty.

Methods

A total of 484 Arabic-speaking adults was recruited between March and April 2024. A self-administered anonymous survey was distributed through social media using a Google Forms link. We used the FACTOR software to conduct the exploratory factor analysis (EFA) of the FUSA scale and RStudio for the confirmatory factor analysis (CFA).

Results

The confirmatory factor analysis of the unidimensional model was poor; the EFA conducted on the first split subsample showed a two-factor solution, with the CFA conducted on the second split subsample showing good fit. The latter model fit indices improved even more after adding a correlation between items 2-5 due to high modification indices. The reliability of the scale was excellent as shown by the McDonald's omega and Cronbach's alpha values for the total score (ω = 0.89 and α = 0.90), Factor 1 = Feeling of outdoor unsafety (ω = 0.91 and α = 0.91) and Factor 2 = Feeling of indoor unsafety (ω = 0.83 and α = 0.83). Invariance was established between males and females. Good concurrent validity was attested by positive correlations between FUSA scores and intolerance of uncertainty dimensions.

Conclusion

The FUSA was found to be reliable, valid, and cost-effective for measuring the general feeling of unsafety in the general population. To evaluate its practical effectiveness and further enhance data on its construct validity, future studies should assess the scale in diverse contexts and among specific populations.

Neighborhood safety, fall indices, physical activity level and social participation restrictions from a population of community-dwelling older adults in Nsukka, Enugu State, Nigeria

BACKGROUND

Restriction in physical activity (PA) and social participation restriction (PR) can be heightened in the presence of fear of fall (FOF), fall experience, and perceived unsafe neighborhood, particularly among older adults. Despite the enormous benefits of social participation and physical activity, many older adults remain vulnerable to participation restriction and this probably accounts for a significant proportion of health challenges for older adults.

OBJECTIVE

This study investigated the relationship between neighborhood safety (NS), fall indices, physical activity, and social participation restriction among older adults from selected communities in Nsukka, Enugu state, Nigeria.

METHODS

This was a cross-sectional survey of 170 recruited via consecutive non-probability sampling techniques. Socio-demographic variables, co-morbidities, and fall prevalence were obtained using a self-administered questionnaire. The study instruments include the PA neighborhood environment scale - Nigeria (PANES-N), PA scale for elderly (PASE), Participation scale (PS), Modified fall efficacy scale (MFES), and Fall risk assessment tool (FRAT) and fall indices.

STATISTICAL ANALYSIS

Descriptive statistics of mean and standard deviations, frequency counts, and percentages were used to analyze the socio-demographic variables, and Inferential statistics of Spearman rank order correlation were used to determine the relationship among the neighborhood safety, fall indices, physical activity level, and participation restrictions.

RESULTS

PR has a negative relationship with NS (r = -0.19, p- 0.01), and fall efficacy (r = -0.52, p- 0.001). However, PR has a positive relationship with fall risk (r = 0.36, p = 0.001).

CONCLUSION

Participation restriction is negatively correlated with neighborhood safety, fall efficacy, and PA. The PR has a positive relationship with fall risk (FR).

Adolescent neighborhood disadvantage and memory performance in young adulthood

OBJECTIVE

Using data from the National Longitudinal Study of Adolescent to Adult Health, we estimated the average causal effect of neighborhood disadvantage in adolescence on memory performance in young adulthood. We contrasted several different ways of operationalizing a continuous measure of neighborhood disadvantage including a continuous neighborhood disadvantage score and ordinal measures.

RESULTS

Neighborhood disadvantage was measured in Wave I when participants were a mean age of 15.41 years (SE: 0.12) and memory performance was measured in Wave IV when participants were a mean age of 28.24 years (SE: 0.12). We found that adolescent neighborhood disadvantage was associated with decreased memory performance in young adulthood. Notably, we observed a linear decline in word recall score among those in the less disadvantaged tail of the distribution (neighborhood disadvantage <1), a finding not observed using traditional ordinal variable classifications of disadvantage.

CONCLUSION

Experiencing neighborhood disadvantage in adolescence may have lasting impacts on cognitive health throughout the life course.

Voices of Experience: What Do Low-Income Older Adults Tell Us About Mobility, Technology, and Social Participation?

Mobility and technology can facilitate in-person and virtual social participation to help reduce social isolation, but issues exist regarding older adults' access, feasibility, and motivation to use various forms of mobility and technology. This qualitative study explores how a diverse group of low-income, urban-living older adults use mobility and technology for social participation. We conducted six focus groups (N = 48), two each in English, Spanish, and Korean at a Los Angeles senior center. Three major themes emerged from thematic analysis: using technology for mobility; links between mobility and social participation; and technology-mediated social participation. Cost, perceived safety, (dis)ability, and support from family and friends were related to mobility and technology use. This study demonstrates the range of mobility and technology uses among older adults and associated barriers. The findings can help establish a pre-COVID-19 baseline on how to make mobility and technology more accessible for older adults at risk of isolation.

Is perceived neighbourhood physical disorder associated with muscle strength in middle aged and older men and women? Findings from the US health and retirement study

BACKGROUND

Research documenting the relevance of neighbourhoods for the health of older adults has focused on global physical functioning outcomes, such as disability, rather than physiologic impairments that lead to disability. Muscle weakness is an age-related impairment and a central mechanism of disability. Evaluating neighbourhood effects on muscle weakness may offer insight into physiologic mechanisms of disability. We examined the association between perceived neighbourhood disorder and muscle strength in a nationally representative sample of US adults aged 51+.

METHODS

Among 11 277 participants (57% women; mean age: 66.6 years) in the Health and Retirement Study (2012-2014), we investigated whether self-reported neighbourhood physical disorder (1-7 scale, mean=2.61, SD=1.45); presence of vandalism/graffiti, litter, deserted houses, feeling safe walking alone) was associated with mean hand grip strength using linear regression models with sampling weights. We tested whether the association between neighbourhood disorder and grip strength differed by age and gender.

RESULTS

After adjusting for demographic characteristics, marital status, education and household wealth, residence in neighbourhoods with high perceived physical neighbourhood disorder was associated with lower muscle strength for men (β=-1.95 kg; 95% CI, 2.68 to -1.22) and to a lesser extent, for women (β=-0.64 kg, 95% CI, -1.11 to -0.19), (p for interaction <0.0001). For both men and women, associations between neighbourhood physical disorder and grip strength were more adverse among the middle aged (51-64 years) than for older (ages 65+) adults.

DISCUSSION

Perceived neighbourhood disorder was associated with lower muscle strength. Future studies should more rigorously evaluate causality and evaluate potential interventions.

Exploring Racial and Ethnic Differences in Recovery Maintenance From Mobility Limitation

Objective: This research examines whether racial and ethnic minorities experience less recovery maintenance (i.e., maintaining their recovery status 2 years later). Method: Using Waves 4-12 (1998-2014) of Health and Retirement Study (HRS), this research examines recovery maintenance among a group of older adults who have previously recovered from mobility limitation. Outcomes included newly acquired mobility limitation (reference), recovery maintenance, and death/attrition. Additional analyses examined whether recovery maintenance predicted disability onset. Results: Analyses used multinomial logistic regression to estimate the odds of recovery maintenance 2 years later. After adjusting for socioeconomic status, there were no significant differences in recovery maintenance among older White and minority adults. Recovery maintenance was a robust predictor of subsequent disability onset; there was suggestive evidence that the effect of recovery maintenance on disability onset varied by race. Discussion: This research provides evidence that the higher rates of recovery among minorities is a form of physical resilience.

Impairments in Individual Autonomous Living Tasks and Time to Self-Care Disability in Middle-Aged and Older Adults

OBJECTIVES

Impairments in specific tasks that are necessary for independent living may identify future self-care limitations, and the use of time-varying covariates can better capture the fluidity in functional capacity trajectories over time. The purpose of this study was to determine the associations between individual instrumental activities of daily living (IADL) impairments and time to activities of daily living (ADL) disability for middle-aged and older adults in the United States.

DESIGN

Longitudinal panel.

SETTING

Detailed interviews that included physical, biological, and psychosocial measures were completed in person. The core interview was typically completed over the telephone.

PARTICIPANTS

A nationally representative sample of 15,336 adults aged at least 50 years from the 2006 wave of the Health and Retirement Study was followed for 8 years.

MEASURES

Ability to perform IADL and ADL were self-reported at each wave. Separate covariate-adjusted Cox models were used to examine the time-varying associations between individual IADL impairments and time to ADL disability.

RESULTS

The presence of each IADL impairment was associated with a higher hazard ratio for an ADL disability for the following functions: 2.52 [95% confidence interval (CI) 2.35, 2.70] for grocery shopping, 1.91 (CI 1.77, 2.06) for preparing hot meals, 1.55 (CI 1.37, 1.76) for taking medications, 1.48 (CI 1.36, 1.61) for managing money, 1.41 (CI 1.27, 1.57) for using a telephone, and 1.38 (CI 1.29, 1.48) for using a map.

CONCLUSIONS/IMPLICATIONS

Our findings provide insights into the disabling process by revealing how impairments in each IADL are differentially associated with time to ADL disability. Interventions aiming to retain function during aging should be informed by fluctuations in IADL performance and how specific IADL impairments may exacerbate functional capacity declines more so than others.

"Taking a Turn for the Better": Does Self-reported Recovery From Walking Limitation Improve Disability and Mortality Outcomes?

Objectives

Recovery from self-reported walking limitation may be a turning point in an individual's health trajectory and may lead to better physical and mental health in the future. This research examines whether recovery from walking limitation is associated with onset of mobility disability, activities of daily living (ADLs) disability, or mortality among a national sample of older Americans.

Data and Methods

Using Waves 4 through 11 (1998-2012) of the Health and Retirement Study (HRS), discrete-time event history models (N = 12,579 person-intervals) with multiple competing events were estimated using multinomial logistic regression. The risk group was defined as respondents with walking limitation, but free of disability. A lagged measure of recovery was created using 2 adjacent waves, and disability and mortality outcomes were assessed in the subsequent wave (i.e., 2 years later).

Results

Recovery from walking limitation (i.e., difficulty walking one or several blocks) was associated with lower odds of mobility disability (i.e., difficulty walking across the room) onset, ADL with mobility disability onset, ADL without mobility disability onset, and mortality. Recovery from walking limitation was not only predictive of mobility-related outcomes, but also nonmobility-related ADLs and mortality-suggesting that the predictive capacity of recovery extends to multiple physical health outcomes.

Discussion

This research suggests that self-reported recovery from walking limitation may be a turning point in the disabling process and signals a meaningful change in an older adult's functional health trajectory.

Muscle Weakness and Physical Disability in Older Americans: Longitudinal Findings from the U.S. Health and Retirement Study

IMPORTANCE

Muscle weakness is an important indicator of disability, chronic disease and mortality. While we recently proposed sex/race specific grip strength cutpoints for clinical muscle weakness in a diverse, nationally representative sample of older Americans, the extent to which these cutpoints predict physical disability remains unknown.

OBJECTIVE

To examine whether sex/race specific muscle weakness cutpoints predict physical disability status in a nationally representative sample of Americans age 65+.

DESIGN

We used data from the 2006-2010 Health and Retirement Study. Fully-adjusted, weighted multinomial logistic regression models were used to quantify the odds of experiencing the onset, progression or persistence of disability in activities of daily living (ADL) among weak versus non-weak individuals over a 2-year period.

SETTING

General community, nationally representative sample of older Americans.

PARTICIPANTS

Population-based, community dwelling sample of older American adults aged 65-years+; 57 percent were women, 91% were White and the mean age was 75 years. Main Outcome(s) and Measure(s): The primary outcome of interest was disability dynamics, defined by changes in ADL status across at 2- year period. The primary exposure was clinical muscle weakness as defined by previously identified cutpoints. Hypotheses were formulated before analyses were conducted.

RESULTS

In this nationally representative sample (n= 8,725), 44% of individuals were classified as weak at baseline. At follow-up, 55% remained independent with no change in their ADL status, 11% had an onset of disability and 4% progressed in their disability status. The odds of experiencing an onset of ADL disability was 54% higher among weak individuals compared those who were not weak at baseline (OR= 1.54, 95% CI= 1.54, 1.5, p<.0001); the odds of experiencing a progression in physical disability status was 2.16 times higher among those who were weak at baseline compared to non-weak individuals (OR= 2.16, 95% CI= 2.15, 2.16, p<.0001).

CONCLUSIONS

This is the first study to use grip strength weakness cut-points to identify those who may be at greatest risk for experiencing physical disability in later life. Results underscore the importance of using population-specific cutpoints for clinical weakness in order to identify individuals at greatest risk for adverse health outcomes.

Neighborhood safety factors associated with older adults' health-related outcomes: A systematic literature review

RATIONALE

Neighborhood safety is important for older adults' health and wellbeing, but there has not been a synthesis in the literature of what is currently known about this construct.

OBJECTIVES

This systematic literature review, following the PRISMA guidelines, focuses on identifying neighborhood safety factors associated with health-related outcomes and behaviors of older adults in the U.S.

METHODS

A search was conducted in 2014 via Academic Search Complete, CINAHL, Embase, MEDLINE, SportDis, and Transportation Databases. Based on our inclusion and exclusion criteria, we identified thirty-two articles for review.

RESULTS

Sixteen studies examined health outcomes such as health status, mental health, physical function, morbidity/mortality, and obesity; the other sixteen studies focused on health behaviors, such as physical activity and walking. Four domains of neighborhood safety were identified: overall/general neighborhood safety; crime-related safety; traffic-related safety; and proxies for safety (e.g., vandalism, graffiti). Overall/general neighborhood safety appeared most relevant to mental health and physical function. Traffic-related safety was most pertinent to physical activity, while crime-related safety was more consistently associated with mental health and walking. While all safety variables were significantly associated with mental health, no significant associations were found for obesity. We also found that specific measures or constructs of safety were not applied consistently across the examined studies, making it difficult to compare the results.

CONCLUSION

This review identified several important gaps in the existing studies dealing with neighborhood safety-health relationships among older adults. Further studies are needed that examine the different roles of multidimensional neighborhood safety in promoting the community health, not only in the U.S., but globally.

Community and social participation among adults with mobility impairments: A mixed methods study

BACKGROUND

Community and social participation is a complex phenomenon that is influenced by personal and environmental factors and is linked to a good quality of life and well-being. Individuals with mobility impairments are at risk of experiencing limitations in participating in community activities due to a wide range of factors.

OBJECTIVE

To understand community participation as defined by adults with mobility impairments and to examine relationships among factors that influence community participation.

METHODS

A mixed-methods study design was used. In-depth interviews of 13 adults with mobility impairments were conducted and themes related to community participation were identified. Data from the Americans' Changing Lives Survey were used to construct variables that mimic the themes from the qualitative phase and structural equation modeling was used to examine the relationships among those variables including community participation.

RESULTS

Individuals with mobility impairments identified health and function, neighborhood factors and self-efficacy as possible factors influencing participation in community activities. Findings from the SEM suggest a strong causal pathway between health and function and community and social participation. Neighborhood factors and health and function had a significant impact on self-efficacy, and a possible indirect effect through self-efficacy on community and social participation.

CONCLUSIONS

Our study provides new empirical evidence that health and function have a significant impact on community and social participation. Our quantitative findings did not support the direct influence of neighborhood factors in community and social participation, yet these factors may have an indirect role by influencing the self-efficacy of individuals with mobility impairments.

Does Neighborhood Disorder Predict Recovery From Mobility Limitation? Findings From the Health and Retirement Study

OBJECTIVE

This research explores whether perceptions of physical neighborhood disorder predict recovery from mobility limitation over a 2-year period and examines whether psychosocial factors (i.e., depressive symptomology and mastery) and physical activity are salient mediators.

METHOD

Using data from the Health and Retirement Study (HRS): Participant Lifestyle Questionnaire (2008-2010), odds ratio estimates of recovery were ascertained using binary logistic regression, and post hoc Sobel tests were conducted to formally assess mediation.

RESULTS

Net of demographic characteristics and socioeconomic status, increased neighborhood disorder was associated with lower odds of recovery. However, both psychosocial indicators and physical activity were significant individual partial mediators, which suggest neighborhood disorder influences recovery from physical impairment via psychosocial processes and barriers to physical activity.

DISCUSSION

Reducing neighborhood disorder may enhance older residents' psychosocial well-being and improve participation in physical activity, thus increasing recovery from mobility limitation and preventing subsequent disability.
