Gender Roles and Physical Function in Older Adults: Cross-Sectional Analysis of the International Mobility in Aging Study (IMIAS)

Sociodemographic Factors in Older Adults' Gait Speed Decline: A Gender Disaggregate Growth Curve Analysis of the Ibadan Longitudinal Study of Ageing

BackgroundGait speed is an important predictor of older adults' well-being. We estimated the influence of sociodemographic factors on the gait speed decline of community-dwelling older Nigerians.MethodsUsing the Ibadan Study of Ageing (2007, 2008, and 2009 cycles), we completed a gender disaggregate analysis of sociodemographic influences on participants' gait speed trajectory using mixed-design ANOVA and growth curve analysis.ResultsAt baseline, 53.2% of participants were female, 61.9% were married, with an average age of 75.5 ± 6.8 years and gait speed of 0.96 ± 0.32 m/s. Gender-specific models showed slower gait speed decline in men (β = -0.05, p < .001) compared to women (β = -0.09, p < .001). Widowhood (β = -0.07, p = .001) for women, high socioeconomic status (β = -0.01, p = .009) for men, and chronic disease burden for women (β = -0.02, p = .010) and men (β = -0.03, p = .008) were significant predictors of gait speed decline.ConclusionAddressing culture-related widowhood and women's vulnerabilities, improving health coverage, and promoting lifestyle modifications may mitigate mobility decline among older Nigerians.

Healthy aging in Vietnam: results from national representative surveys on older persons

This study constructed the Healthy Aging Index (HAI) and identified its associated factors, using two waves of nationally representative data on the Vietnamese older persons in 2019 and 2022. HAI was constructed with 22 variables reflecting various domains of healthy aging, and its measurement ranged from 0 to 100. Descriptive statistics and multivariate Tobit regressions were conducted. We found that the overall HAI scores were relatively high in 2019 and 2022 (84.05 and 83.71, respectively), indicating that the Vietnamese older persons were relatively healthy. More advanced age, being women, living with at least a child, living with a spouse, being more affluent, having higher educational level, receiving social welfare benefits, performing household chores, and utilization of healthcare services were associated with the overall HAI scores as well as each factor of HAI scores. This study also discussed policies that can be designed to enhance well-being of older persons in Vietnam, including the investment in higher educational training, lifelong learning programs for older adults, increasing pension and social welfare benefits together with enhancing healthcare delivery for vulnerable groups, and the development of an integrated care model combining health and social care.

Sociodemographic determinants of mobility decline among community-dwelling older adults: findings from the Canadian longitudinal study on ageing

BACKGROUND

Mobility is fundamental to healthy ageing and quality of life. Mobility decline has been associated with functional impairment, falls, disability, dependency, and death among older adults. We explored the sociodemographic determinants of mobility decline among community-dwelling older Canadians.

METHODS

This study was a secondary analysis of a six-year follow-up of the Canadian Longitudinal Study on Ageing (CLSA). Our analysis was based on 3882 community-dwelling older adults 65 years or older whose mobility was measured using timed-up and go (TUG) and 4-meter walk (4MWT) tests at baseline and follow-ups 1 and 2 after three- and six-year intervals, respectively. We analysed the cross-sectional and longitudinal association, main and interaction effects of the participants' sociodemographic characteristics on mobility decline using chi-square, Pearson's correlation, mixed-design repeated measures ANOVA, and bivariate and multivariate linear regression tests.

RESULTS

At baseline, 52% of the participants were female, 70.4% were married, and the average age was 68.82 ± 2.78 years. Mean TUG and 4MWT scores were 9.59 ± 1.98 s and 4.29 ± 0.95 s, respectively. There was a strong positive longitudinal correlation between TUG and 4MWT (r = 0.65 to 0.75, p < 0.001), indicating concurrent validity of 4MWT. The multivariate linear regression (for TUG) showed that older age (β = 0.088, p < 0.001), being a female (β=-0.035, p < 0.001), retired (β=-0.058, p < 0.001), Canadian born (β=-0.046, p < 0.001), non-Caucasian (β=-0.063, p < 0.001), tenant (β = 0.050, p < 0.001), having no spouse/partner (β=-0.057, p < 0.001), household income of $50,000-$99,999 (β = 0.039, p < 0.001), wealth/investment lower than $50,000 (β=-0.089, p < 0.001), lower social status (β=-0.018,p = 0.025), secondary education and below (β = 0.043, p < 0.001), and living in certain provinces compared to others, were significant predictors of a six-year mobility decline.

CONCLUSION

Our study underscored the impact of modifiable and non-modifiable sociodemographic determinants of mobility trajectory. There is a need for nuanced ageing policies that support mobility in older adults, considering sociodemographic inequalities through equitable resource distribution, including people of lower socioeconomic backgrounds.

Exercise-based interventions targeting balance and falls in people with COPD: a systematic review and meta-analysis

INTRODUCTION

This review quantifies the mean treatment effect of exercise-based interventions on balance and falls risk in people with COPD.

METHODS

A structured search strategy (2000-2023) was applied to eight databases to identify studies evaluating the impact of exercise-based interventions (≥14 days in duration) on balance or falls in people with COPD. Pooled mean treatment effects (95% confidence intervals (CIs), 95% prediction intervals (PIs)) were calculated for outcomes reported in five or more studies. Inter-individual response variance and the promise of behaviour change techniques (BCTs) were explored.

RESULTS

34 studies (n=1712) were included. There were greater improvements in balance post intervention compared to controls for the Berg Balance Scale (BBS) (mean 2.51, 95% CI 0.22-4.80, 95% PI -4.60-9.63), Timed Up and Go (TUG) test (mean -1.12 s, 95% CI -1.69- -0.55 s, 95% PI -2.78-0.54 s), Single-Leg Stance (SLS) test (mean 3.25 s, 95% CI 2.72-3.77 s, 95% PI 2.64-3.86 s) and Activities-specific Balance Confidence (ABC) scale (mean 8.50%, 95% CI 2.41-14.58%, 95% PI -8.92-25.92%). Effect on falls remains unknown. Treatment effects were larger in male versus mixed-sex groups for the ABC scale and SLS test, and in balance training versus other exercise-based interventions for the BBS and TUG test. Falls history was not associated with changes in balance. Meta-analysis of individual response variance was not possible and study-level results were inconclusive. Eleven promising BCTs were identified (promise ratio ≥2).

CONCLUSION

Evidence for the effect of exercise-based interventions eliciting clinically important improvements in balance for people with COPD is weak, but targeted balance training produces the greatest benefits. Future exercise interventions may benefit from inclusion of the identified promising BCTs.

Prevalence of secondary prosthesis use in lower limb prosthesis users

PURPOSE

Prostheses designed for daily use are often inappropriate for high-level activities and/or are susceptible to water damage and mechanical failure. Secondary prostheses, such as activity-specific or back-up prostheses, are typically required to facilitate uninterrupted participation in desired life pursuits. This study estimated the prevalence of secondary prosthesis use in a large, national sample of lower limb prosthesis users (LLPUs).

METHODS

We conducted a secondary analysis of survey data from three cross-sectional studies that assessed mobility in LLPUs. Descriptive statistics were used to determine the percentage of secondary prosthesis users and percentages of LLPUs that used different type(s) of secondary prosthesis(es). Secondary prosthesis users and non-users were compared to identify differences in participant characteristics between groups.

RESULTS

Of participants in the analysis (n = 1566), most (65.8%) did not use a secondary prosthesis. The most common secondary prosthesis types were back-up (19.2%) and activity-specific prostheses (13.5%). Secondary prosthesis users differed significantly from non-users with respect to gender, race, and other characteristics.

CONCLUSIONS

Results suggest that secondary prosthesis use for most LLPUs is limited and may differ based on users' demographic and clinical characteristics. Future research should determine how LLPUs' health-related quality-of-life outcomes are affected by access to and use of secondary prostheses.Implications for RehabilitationSecondary prostheses, including activity-specific, back-up, and shower prostheses, have the potential to improve function, mobility, and participation for people who use lower limb prostheses.Most lower limb prosthesis users do not use secondary prostheses, and access to these devices may be related to users' demographic and clinical characteristics.Rehabilitation professionals play a key role in facilitating prosthesis users' access to secondary prostheses and should advocate for those who need them.

Exploring How Older Adult's Gender Role is Associated with Studied Outcomes Following an Outdoor Exercise Structure Program

This study aimed to describe the gender roles of people interested in an exercise program done on outdoor exercise structures and test if gender roles were associated with studied outcomes. Older adults aged 65+ who were not currently performing resistance training were invited to participate. Gender roles were quantified using the Bem Sex Role Inventory 30-item questionnaire (-60 [feminine] to +60 [masculine]). Outcomes included completing the 6-week intervention (Y/N) and changes in physical function (one leg stance, 30-s chair stand), strength (predicted maximal chest press and leg press, grip strength), power (knee extensor power), and overall health via the SF-36 questionnaire. Twenty-nine adults (65.5% female; median 72 years old) participated in the study, and 17 completed the intervention (58.6%). The median (interquartile) gender role score was -13.0 (-19.5 to -8.5), with no gender role difference (p = .62) between completers and non-completers. These results suggest that older adults interested in such a program portray themselves as more feminine. No association was found between gender role scores and changes in any study outcomes. In this setting, gender roles did not seem to impact the study outcomes and therefore may not need to be considered when designing an outdoor exercise structure program.

A Scoping Review of Personal, Financial, and Environmental Determinants of Mobility Among Older Adults

OBJECTIVE

To synthesize available evidence of factors comprising the personal, financial, and environmental mobility determinants and their association with older adults' self-reported and performance-based mobility outcomes.

DATA SOURCES

PubMed, EMBASE, PsychINFO, Web of Science, AgeLine, Sociological Abstract, Allied and Complementary Medicine Database, and Cumulative Index to Nursing and Allied Health Literature databases search for articles published from January 2000 to December 2021.

STUDY SECTION

Using predefined inclusion and exclusion criteria, multiple reviewers independently screened 27,293 retrieved citations from databases, of which 422 articles underwent full-text screening, and 300 articles were extracted.

DATA EXTRACTION

The 300 articles' information, including study design, sample characteristics including sample size, mean age and sex, factors within each determinant, and their associations with mobility outcomes, were extracted.

DATA SYNTHESIS

Because of the heterogeneity of the reported associations, we followed Barnett et al's study protocol and reported associations between factors and mobility outcomes by analyses rather than by article to account for multiple associations generated in 1 article. Qualitative data were synthesized using content analysis. A total of 300 articles were included with 269 quantitative, 22 qualitative, and 9 mixed-method articles representing personal (n=80), and financial (n=1), environmental (n=98), more than 1 factor (n=121). The 278 quantitative and mixed-method articles reported 1270 analyses; 596 (46.9%) were positively and 220 (17.3%) were negatively associated with mobility outcomes among older adults. Personal (65.2%), financial (64.6%), and environmental factors (62.9%) were associated with mobility outcomes, mainly in the expected direction with few exceptions in environmental factors.

CONCLUSIONS

Gaps exist in understanding the effect of some environmental factors (eg, number and type of street connections) and the role of gender on older adults' walking outcomes. We have provided a comprehensive list of factors with each determinant, allowing the creation of core outcome set for a specific context, population, or other forms of mobility, for example, driving.

The intersection of biological sex and gender in adverse events following seasonal influenza vaccination in older adults

BACKGROUND

Women/females report more adverse events (AE) following immunization than men/males for many vaccines, including the influenza and COVID-19 vaccines. This discrepancy is often dismissed as a reporting bias, yet the relative contributions of biological sex and gender are poorly understood. We investigated the roles of sex and gender in the rate of AE following administration of the high-dose seasonal influenza vaccine to older adults (≥ 75 years) using an AE questionnaire administered 5-8 days post-vaccination. Participant sex (male or female) was determined by self-report and a gender score questionnaire was used to assign participants to one of four gender categories (feminine, masculine, androgynous, or undifferentiated). Sex steroid hormones and inflammatory cytokines were measured in plasma samples collected prior to vaccination to generate hypotheses as to the biological mechanism underpinning the AE reported.

RESULTS

A total of 423 vaccines were administered to 173 participants over four influenza seasons (2019-22) and gender data were available for 339 of these vaccinations (2020-22). At least one AE was reported following 105 vaccinations (25%), by 23 males and 82 females. The majority of AE occurred at the site of injection, were mild, and transient. The odds of experiencing an AE were 3-fold greater in females than males and decreased with age to a greater extent in females than males. The effects of gender, however, were not statistically significant, supporting a central role of biological sex in the occurrence of AE. In males, estradiol was significantly associated with IL-6 and with the probability of experiencing an AE. Both associations were absent in females, suggesting a sex-specific effect of estradiol on the occurrence of AE that supports the finding of a biological sex difference.

CONCLUSIONS

These data support a larger role for biological sex than for gender in the occurrence of AE following influenza vaccination in older adults and provide an initial investigation of hormonal mechanisms that may mediate this sex difference. This study highlights the complexities of measuring gender and the importance of assessing AE separately for males and females to better understand how vaccination strategies can be tailored to different subsets of the population.

Consideration of sex/gender in publications of quantitative health-related research: Development and application of an assessment matrix

During the last years the need to integrate sex and gender in health-related research for better and fairer science became increasingly apparent. Various guidelines and checklists were developed to encourage and support researchers in considering the entangled dimensions of sex/gender in their research. However, a tool for the assessment of sex/gender consideration and its visualization is still missing. We aim to fill this gap by introducing an assessment matrix that can be used as a flexible instrument for comprehensively evaluating the sex/gender consideration in quantitative health-related research. The matrix was developed through an iterative and open process based on the interdisciplinary expertise represented in our research team and currently published guidelines. The final matrix consists of 14 different items covering the whole research process and the publication of results. Additionally, we introduced a method to graphically display this evaluation. By developing the matrix, we aim to provide users with a tool to systematically compare sex/gender consideration qualitatively between different publications and even different fields of study. This way, the assessment matrix represents a tool to identify research gaps and a basis for future research. In the long term, the implementation of this tool to evaluate the consideration of sex/gender should contribute to more sex/gender equitable health-related research.

Prevalence of depression among elderly women in India-An intersectional analysis of the Longitudinal Ageing Study in India (LASI), 2017-2018

Epidemiological transition in India shows a shift in disease burden from youth to the elderly. As Life Expectancy increases, a greater burden is placed on the state, society, and families in India. Mental health disorders are insidious, debilitating Non-Communicable Diseases (NCDs) that afflict people, their families, and generations down the line. Globally, depression is the leading cause of mental health-related disability. It is estimated that mental illness contributes to 4.7% of Disability Adjusted Life Years (DALYs) in India. It is predicted that by 2026, the elderly's sex ratio will increase to 1,060 feminizing ageing. Research has shown that elderly women in developed countries like the United States are more prone to depression. Chronic morbidities are more common in women than in men, and they may suffer from poor vision, depression, impaired physical performance, and elder abuse. Mostly widowed, economically dependent, lacking proper food and clothing, fearing the future, and lacking proper care, they have difficulty coping with these health problems. There are surprisingly few studies on elderly female depression. Therefore, we want to hypothesize the prevalence of depression among women in different regions and demographic groups in India, and what factors may contribute to these differences. Using intersectional analysis with the data from Wave 1 (2017-2018) of the (Longitudinal Ageing Study in India) LASI (N = 16,737) we were able to explore the intersecting patterns between different variables and how people are positioned simultaneously and position themselves in different multiple categories based on the type of place of residence, age and level of education. Through the study we further aim to determine the prevalence of depression among elderly female in the age group of 60 in different states using the Chloropleth map. The findings of the study highlight the significance of the place of residence in the development of depression among elderly women, with the rural area being associated with a higher prevalence of depression compared to urban area. When compared to people with higher literacy, those with low literacy were significantly associated with depression. State-wise, there is a huge difference between the prevalence of elderly women depression in rural and urban areas. The study highlights the vulnerability of elderly women to depression. It is possible for the government to develop programs that address the needs of elderly women, both in urban and rural areas, to reduce depression. Multi-factor approaches to mental health, which consider age, literacy, and location, are essential. Programs targeting specific populations can be developed to address depression's root causes..

Gender-Specific Associations between Late-Life Disability and Socioeconomic Status: Findings from the International Mobility and Aging Study (IMIAS)

Disability is a dynamic process and can be influenced by a sociocultural environment. This study aimed to determine whether the associations between socioeconomic status and late-life disability differ by gender in a multi-sociocultural sample from different countries. A cross-sectional study was developed with 1362 older adults from The International Mobility in Aging Study. Late-life disability was measured through the disability component of the Late-Life Function Disability Instrument. Level of education, income sufficiency and lifelong occupation were used as indicators of SES. The results indicated that a low education level β = -3.11 [95% CI -4.70; -1.53] and manual occupation β = -1.79 [95% -3.40; -0.18] were associated with frequency decrease for men, while insufficient income β = -3.55 [95% CI -5.57; -1.52] and manual occupation β = -2.25 [95% CI -3.89; -0.61] played a negative role in frequency for women. For both men β = -2.39 [95% -4.68; -0.10] and women β = -3.39 [95% -5.77; -1.02], insufficient income was the only factor associated with greater perceived limitation during life tasks. This study suggested that men and women had different late-life disability experiences. For men, occupation and education were associated with a decrease in the frequency of participation, while for women this was associated with income and occupation. Income was associated with perceived limitation during daily life tasks for both genders.

Gender Differences in Disease, Function, and Behavioral Symptoms in Residents with Dementia

The purpose of this study was to consider gender differences in depressive symptoms, agitation, resistiveness to care, physical function, and use of psychotropic medications in older adults with moderate to severe dementia in nursing homes. Sixty-seven nursing homes and 889 residents from two states were included. The majority of the participants were female (n = 640, 72%) and White (n = 618, 70%) with a mean age of 86.58 years (SD = 10.31). Differences by gender with regard to age, physical function, depressive symptoms, agitation/aggression, and resistiveness to care were tested using multivariate analysis of variance. Older females with moderate to severe dementia present with more depressive symptoms (anxiety, sadness, and somatic complaints) than males. Males present with more aggressive behavior and are more likely to receive anticonvulsants. Caregivers should focus on preventing and managing depressive symptoms including anxiety, sadness, and somatic complaints among older females and aggressive behavior in older males with dementia.

Is being gender nonconforming distressing? It depends where you live: gender equality across 15 nations predicts how much gender nonconformity is related to self-esteem

BACKGROUND

Individuals exhibiting gender nonconforming behaviors experience low self-esteem and a number of other mental health conditions, including elevated suicide risk. Most of the relevant evidence is confined to US studies, however. Adopting a cross-national approach, we examined the pervasiveness of the psychological burden associated with gender nonconformity. Because self-esteem is sensitive to the fulfillment of societal expectations for gender conformity, we reasoned that the relationship between gender conformity and self-esteem ought to decrease as societies become less restrictive in their gender norms.

METHODS

To test this proposition, we conducted two studies including 18 national samples from 15 countries varying in gender equality. Participants responded to an online survey that included measures of gender conformity and self-esteem (N = 4486).

RESULTS

Using multilevel analyses and meta-analytic statistics over the samples of both studies, we found that as gender equality increased, the association between gender conformity and self-esteem decreased.

CONCLUSIONS

The results suggest that rather than being inherently noxious, gender non-conformity becomes detrimental to self-esteem when it clashes with restrictive gender role norms that are enacted by the macrosocial context. We suggest that previous findings on psychological problems related to gender nonconformity be considered within a broader macrosocial context that may constrain people's freedom to move against gender role norms.

Sex-Specific Differences in Lower Body Fat Distribution and Association with Physical Performance among Healthy Community-Dwelling Older Adults: A Pilot Study

This study aims to examine sex-specific differences in body composition and lower extremity fat distribution and their association with physical performance among healthy older adults. The pilot study comprises 40 subjects (20 men and 20 women) matched by age and body mass index. The participants undergo dual-energy X-ray absorptiometry, magnetic resonance imaging, and proton magnetic resonance spectroscopy (¹H-MRS) to assess body composition and lower extremity fat distribution. ¹H-MRS is used to measure the extramyocellular lipid (EMCL) and intramyocellular lipid (IMCL) contents of the lower leg muscles (soleus and tibialis anterior) at the maximum circumference of the calf after overnight fasting. The tibialis anterior IMCL, as assessed by ¹H-MRS, is negatively associated with the five-times sit-to-stand test scores (r_s = 0.518, p = 0.023) in men, while the soleus IMCL content is negatively associated with the timed up-and-go test scores (r_s = 0.472, p = 0.048) in women. However, the soleus EMCL content is positively associated with the five-times sit-to-stand test scores (r_s = −0.488, p = 0.040) in women, but this association is not statistically significant in men. This study shows an inverse correlation between IMCL content and physical performance in healthy older individuals and lower leg muscle-specific IMCL based on sex differences. Furthermore, our results suggest that greater EMCL content in the soleus and calf subcutaneous fat might affect physical performance positively in women but not men.

Fatores associados à limitação da mobilidade funcional em idosos do Município de São Paulo, Brasil: análise comparativa ao longo de 15 anos

Este estudo teve como objetivo analisar a prevalência de limitação na mobilidade funcional autorreferida e os fatores associados no período entre os anos 2000 e 2015, em idosos residentes no Município de São Paulo, Brasil. Para as presentes análises foram utilizados os dados das quatro ondas (2000, 2006, 2010 e 2015) do Estudo Saúde, Bem Estar e Envelhecimento (SABE). Foram conduzidos modelos de regressão para analisar as características demográficas, socioeconômicas, comportamentais e relativas à saúde dos indivíduos associadas à limitação da mobilidade em cada onda do estudo, e análise multinível para a comparação entre as quatro ondas. Os resultados indicaram aumento nas prevalências de limitações na mobilidade autorreferida, mais evidente no ano de 2006. Foi observado, ainda, associação com condições crônicas de saúde, como a história de AVC (RP = 1,43; IC95%: 1,29; 1,58, em 2000), a presença de doenças osteoarticulares (RP = 1,35; IC95%: 1,23; 1,49, em 2015), e a queixa de “dor nas costas” (RP = 1,33; IC95%: 1,22; 1,45, em 2006), bem como com aspectos socioeconômicos, como a renda insuficiente (RP = 1,17; IC95%: 1,07; 1,28, em 2010). Em um contexto de envelhecimento populacional acelerado, esses resultados trazem informações relevantes para a promoção de políticas públicas voltadas à prevenção de declínio da mobilidade em pessoas idosas.

Gender roles and intimate partner violence among female university students in Spain: A cross-sectional study

BACKGROUND

Traditional gender roles (GRs) have a considerable influence on relationships among couples. These can lead to negative health effects in women; however, their impact on intimate partner violence (IPV) has been less explored, especially among younger women.

OBJECTIVE

To explore the association between traditional GRs and several indicators of IPV on a sample of Spanish female university students involved in heterosexual dating relationships.

METHODS

A cross-sectional study involving female university students (n = 1,005) pursuing ten degrees (four Health Science degrees and six Social Sciences degrees). Data were collected using two validated scales: 1) the Questionnaire on the Gender Determinants of Contraception (COGANT), used to examine four traditional GRs (submissive, blind, and passive attitudes of female students, and male dominance), and 2) the Dating Violence Questionnaire-R (DVQ-R) scale, used to measure five types of IPV-behaviors (coercion, detachment, humiliation, sexual violence, and physical violence), perceived fear, entrapment, and abuse. Logistic and linear regressions were conducted to study the association between GR and a series of IPV indicators in dating relationships.

RESULTS

Traditional GRs were highly prevalent (57.0% submissive, 52.0% blind attitude, 75.7% passive, and 31.7% identified their boyfriend as being dominant). Up to 66.3% experienced some type of violent behavior. All GRs were significantly associated with IPV indicators. A submissive attitude in female students was the GR that was most strongly associated to total IPV-behavior (adjusted odd ratio [OR] = 3.18; 95% confidence interval [CI]: 2.29-4.42), followed by male dominance (OR = 2.79: 95% CI:1.71: 4.54). Both GRs were also highly associated with perceived fear, entrapment, and abuse.

CONCLUSIONS

A high presence of traditional GRs was found in the relationships held by female university students, which was significantly associated with IPV indicators. Universities must adopt policies for gender equality and raise awareness on dating violence.

Testing the effectiveness of community-engaged citizen science to promote physical activity, foster healthier neighborhood environments, and advance health equity in vulnerable communities: The Steps for Change randomized controlled trial design and methods

While low-income midlife and older adults are disproportionately affected by non-communicable diseases that can be alleviated by regular physical activity, few physical activity programs have been developed specifically with their needs in mind. Those programs that are available typically do not address the recognized local environmental factors that can impact physical activity. The specific aim of the Steps for Change cluster-randomized controlled trial is to compare systematically the initial (one-year) and sustained (two-year) multi-level impacts of an evidence-based person-level physical activity intervention (Active Living Every Day [ALED] and age-relevant health education information), versus the ALED program in combination with a novel neighborhood-level citizen science intervention called Our Voice. The study sample (N = 300) consists of insufficiently active adults ages 40 years and over living in or around affordable senior public housing settings. Major study assessments occur at baseline, 12, and 24 months. The primary outcome is 12-month change in walking, and secondary outcomes include other forms of physical activity, assessed via validated self-report measures supported by accelerometry, and physical function and well-being variables. Additional intervention impacts are assessed at 24 months. Potential mediators and moderators of intervention success will be explored to better determine which subgroups do best with which type of intervention. Here we present the study design and methods, including recruitment strategies and yields. TRIAL REGISTRATION: clinicaltrial.gov Identifier = NCT03041415.

Life Experiences of Older Men Living Alone With Depression

As the percentage of older adults living alone increases, social interest has been drawn to this physically, financially, and socially vulnerable group. The purpose of the current study was to gain a deeper understanding of the life experiences of older men with depression who live alone. Eight community-dwelling men aged ≥65 years who lived alone in Korea and had depression were enrolled in this study. Data were collected via individual in-depth interviews and analyzed using thematic analysis. Four themes emerged from analysis: Life Trapped in the Traditional Masculine Ideology, Weakening Mind and Body, Lost and Helpless, and Beginning of Communication With the World. Results of this study will be helpful in developing more effective depression intervention programs for older men living alone by increasing community health care professionals' understanding and sensitivity.

The sex difference in gait speed among older adults: how do sociodemographic, lifestyle, social and health determinants contribute?

Background

This study explores whether a sex difference in sensitivity to (strength of the association) and/or in exposure to (prevalence) determinants of gait speed contributes to the observed lower gait speed among older women compared to men.

Methods

Data from the Longitudinal Aging Study Amsterdam (LASA) were used. In total 2407 men and women aged 55–81 years were included, with baseline measurements in 1992/2002 and follow-up measurements every 3–4 years for 15/25 years. Multivariable mixed model analysis was used to investigate sex differences in sensitivity (interaction term with sex) and in exposure to (change of the sex difference when adjusted) socio-demographic, lifestyle, social and health determinants of gait speed.

Results

Women had a 0.054 m/s (95 % CI: 0.076 − 0.033, adjusted for height and age) lower mean gait speed compared to men. In general, men and women had similar determinants of gait speed. However, higher BMI and lower physical activity were more strongly associated with lower gait speed in women compared to men (i.e. higher sensitivity). More often having a lower educational level, living alone and having more chronic diseases, pain and depressive symptoms among women compared to men also contributed to observed lower gait speed in women (i.e. higher exposure). In contrast, men more often being a smoker, having a lower physical activity and a smaller personal network size compared to women contributed to a lower gait speed among men (i.e. higher exposure).

Conclusions

Both a higher sensitivity and higher exposure to determinants of gait speed among women compared to men contributes to the observed lower gait speed among older women. The identified (modifiable) contributing factors should be taken into account when developing prevention and/or treatment strategies aimed to enhance healthy physical aging. This might require a sex-specific approach in both research and clinical practice, which is currently often lacking.

Falls and life-space mobility: longitudinal analysis from The International Mobility in Aging Study

OBJECTIVES

To investigate a 4-year longitudinal relationship between falls, recurrent falls, and injurious falls, according to different levels of life-space mobility (LSM).

METHODS

Longitudinal analysis of an international cohort study. The participants were older adults from the International Mobility in Aging Study (IMIAS) aged between 65 and 74 years at baseline. Three waves of data (2012, 2014, 2016) were used. Fall history during the past year was recorded. Recurrent fallers were identified as those who fell at least twice and injurious fallers as participants who required medical attention. LSM measurements included Total Life-Space (LS-C), Maximal Life-Space (LS-M), Assisted Life-Space (LS-A), Independent Life-Space (LS-I) and Restricted Life-space (LS-ID) scores. Generalized estimation equation (GEE) models were used to determine whether life-space mobility measures and their change over time differed between recurrence of falls and injurious falls.

RESULTS

At baseline, the prevalence of falls in the last year was 28%. 11.8% reported recurrent falls and 2.6% had serious injurious falls in the last year preceding the assessments. Recurrent fallers were more likely to be female, with insufficient income and, with comorbidities. GEE models showed that life-space mobility was lower among those with recurrent falls or serious injurious falls compared to those who never fell, but the rate of change did not differ over the 4-year follow-up except for the LS-A and LS-I scores, where some improvements were observed over time.

CONCLUSIONS AND IMPLICATIONS

Falls were independently associated with a decrease in LSM over 4 years. Targeting older adults with recurrent and injurious falls with appropriate interventions may improve community mobility and social participation.

Physical performance and activity among older adults visiting primary healthcare centres in Riyadh

Objective

To assess physical performance (PP) and physical activity (PA) among older adults visiting primary healthcare centres (PHCCs) in Riyadh.

Methods

In this cross-sectional study, men and women (n = 74) aged ≥60 years were recruited from five PHCCs across Riyadh, Saudi Arabia, between 19 February and 6 August 2017. The Timed Up & Go test was used to assess PP. Self-reported PA was assessed using the Physical Activity Scale for the Elderly. Means and standard deviations were used to describe PP and PA scores across genders. A two-tailed independent samples t-test was used to estimate mean differences (MD) and 95% confidence intervals (CI) between genders.

Results

Men scored significantly lower than women on PP (MD: 2.11, 95% CI: 0.59 to 3.64) and PA (MD: −46.1, 95% CI: −80.96 to −11.25). Significant gender differences were observed for leisure time activities (MD: 17.35, 95% CI: 3.29 to 31.40), light household activities (MD: –10.86, 95% CI: –16.19 to –5.53) and heavy household activities (MD: –6.48, 95% CI: –11.73 to –1.23).

Conclusions

Men show significantly lower PP and PA than women. There are gender differences in leisure time activities and in light and heavy household activities.

Giving Voice to the Environment as the Silent Partner in Aging: Examining the Moderating Roles of Gender and Family Structure in Older Adult Wellbeing

Gerontological scholarship has long seen the environment to be a silent partner in aging. Environmental Gerontology, an established approach in Social Gerontology, has shown how the everyday lives of older adults are deeply entangled in socio-spatial environments. Adopting an Environmental Gerontology approach, we explore social and cultural dimensions of the association between out-of-home mobility and wellbeing among older adults in a north western city of India. This was established by combining high resolution time-space data collected using GPS receivers, questionnaire data and time diaries. Following a multi-staged analytical strategy, we first examine the correlation between out-of-home mobility and wellbeing using bivariate correlation. Second, we introduce gender and family structure into regression models as moderating variables to improve the models' explanatory power. Finally, we use our results to reinterpret the Ecological Press Model of Aging to include familial structure as a factor that moderates environmental stress. Findings emphasize the central role that social constructs play in the long-established relationship between the environment and the wellbeing of older adults.

Understanding the Meaning of Conformity to Feminine Norms in Lifestyle Habits and Health: A Cluster Analysis

Background: Gender roles impact different spheres of life and lead women to behavioral patterns and lifestyle habits associated with femininity, generating important differences between men and women in health. The present study analyzed relationships between conformity to the feminine norms and different lifestyle indicators: Educational level, marital status, alcohol consumption, tobacco consumption, sleeping hours, social support, and physical activity. Additionally, cluster analysis was developed in order to identify different patterns of gender role conformity. Methods: The sample was made up of 347 women age 18-70 from Spain. Data collection was conducted during 2014. Results: Multiple logistic regression analyses produced odds ratios showing that women with lower feminine role conformity were more likely to use tobacco and alcohol, but less likely to share their lives with someone. Cluster analysis found four different profiles of gender role conformity related to different patterns of alcohol consumption and marital status. Conclusions: Conformity to feminine norms was associated with basic affective conditions such as sharing life with others and with alcohol and tobacco consumption, but not with physical activity, social support, and sleep duration. Whereas tobacco and alcohol use have important health implications, public health systems should pay attention to gender-related variables in order to design and implement specific prevention programs.

Gender Differences in Function, Physical Activity, Falls, Medication Use, and Life Satisfaction Among Residents in Assisted Living Settings

The purpose of the current study was to test for gender differences among residents living in assisted living settings. This was a secondary data analysis using data from the first 64 facilities participating in the ongoing Function Focused Care for Assisted Living study using the Evidence Integration Triangle (FFC-AL-EIT). A total of 593 residents were recruited. Differences by gender with regard to function, physical activity, falls, total number of medications, and satisfaction with assisted living were tested using multivariate analysis of variance. There were 166 (28%) men and 427 (72%) women with a mean age of 88 (SD = 7.5 years). Participants had five (SD = 2) comorbidities and took on average 6.88 medications (SD = 3.47). Participants had moderate functional impairment with a mean of 64.13 (SD = 19.09) on the Barthel Index and engaged in 43.8 (SD = 76.12) minutes daily of moderate level physical activity. Women reported higher satisfaction with activities (4.32 [SD = 1.14]) than men (3.85 [SD = 1.51]), and women received more medications than men (7.09 [SD = 3.51] vs. 6.34 [SD = 3.31]). Current study findings suggest that deprescribing may be particularly important for women versus men and focusing on expanding activity options to include those preferred by men should be considered in assisted living settings.

The relationship between gender roles and self-rated health: A perspective from an international study

OBJECTIVES

To examine the relationship between gender roles and self-rated health in older men and women from different contexts.

METHODS

2002 community-dwelling older adults from the International Mobility in Aging Study were recruited from 5 research sites. Gender role was measured with the 12-item Bem Sex Role Inventory, which categorized study participants into four gender roles: Masculine, Feminine, Androgynous, and Undifferentiated. Self-rated health was collapsed into a dichotomous variable (Very Good/Good and Fair/Poor/Very Poor). Prevalence risk ratios (PRR) of self-rated health relative to gender roles were estimated with Poisson regression models adjusted for all relevant confounders.

RESULTS

After complete adjustment, feminine (PRR 1.22 (95 % CI 1.01-1.49)) and undifferentiated (PRR 1.25 (95 % CI 1.05-1.50)) gender roles were associated with poorer relative self-rated health.

DISCUSSION

Gender roles confer independent risks and benefits for self-rated health in older adults.

Gender norms and health: insights from global survey data

Despite global commitments to achieving gender equality and improving health and wellbeing for all, quantitative data and methods to precisely estimate the effect of gender norms on health inequities are underdeveloped. Nonetheless, existing global, national, and subnational data provide some key opportunities for testing associations between gender norms and health. Using innovative approaches to analysing proxies for gender norms, we generated evidence that gender norms impact the health of women and men across life stages, health sectors, and world regions. Six case studies showed that: (1) gender norms are complex and can intersect with other social factors to impact health over the life course; (2) early gender-normative influences by parents and peers can have multiple and differing health consequences for girls and boys; (3) non-conformity with, and transgression of, gender norms can be harmful to health, particularly when they trigger negative sanctions; and (4) the impact of gender norms on health can be context-specific, demanding care when designing effective gender-transformative health policies and programmes. Limitations of survey-based data are described that resulted in missed opportunities for investigating certain populations and domains. Recommendations for optimising and advancing research on the health impacts of gender norms are made.

The Intersection of Physical Function, Cognitive Performance, Aging, and Multiple Sclerosis: A Cross-sectional Comparative Study

OBJECTIVE

To examine the associations between physical function (walking speed and endurance and functional mobility) and cognitive function (information processing speed and verbal memory) in older adults with multiple sclerosis (MS) and healthy controls.

BACKGROUND

Older adults with MS have worse physical and cognitive function than older adults without MS and young and middle-aged adults with MS. To date, little is known about the associations between, or coupling of, physical and cognitive function outcomes in older adults with MS.

METHODS

We administered physical and cognitive function measures to 40 older adults with MS and 40 demographically matched healthy controls. Pearson product moment correlations were used to examine bivariate linear relationships in the overall sample and in the subsamples of (a) older adults with MS and (b) healthy controls. Linear regression analyses were used to examine the independent associations between demographic characteristics and physical and cognitive function variables in the two subsamples.

RESULTS

In the overall sample, all physical function variables were significantly correlated with cognitive function, as measured by information processing speed, and these correlations were mainly due to the subsample of older adults with MS. The linear regression analyses further indicated that information processing speed and years of education consistently explained variance in all physical function variables, beyond the influence of demographic variables, in older adults with MS.

CONCLUSIONS

Physical function and information processing speed are strongly correlated in older adults with MS. Future research should examine underlying neurobehavioral mechanisms associated with physical and cognitive function as well as behavioral strategies for jointly improving these functions in older adults with MS.

Urinary Incontinence Is Associated With Physical Performance Decline in Community-Dwelling Older Women: Results From the International Mobility in Aging Study

Objective: The objective of this study is to evaluate the influence of urinary incontinence (UI) on physical performance. Method: In prospective analyses from the International Mobility in Aging Study (IMIAS), 915 women (65-74 years) from Canada, Colombia, Albania, and Brazil were evaluated in relation to self-reported UI (past week) and physical performance (Short Physical Performance Battery [SPPB]), with reevaluation after 2 years. Linear mixed models examined the influence of UI on SPPB, adjusted by covariates (age, study site, education, income sufficiency, body mass index [BMI] and parity). Results: Women reporting some UI presented lower SPPB mean (β = -0.41, p = .009) and a greater reduction (β = -0.53, p = .001) over 2 years than those reporting no UI. Discussion: Compared with no reported UI, some UI was associated with worse and more pronounced declines in physical performance over 2 years. This study highlights the importance of practices to reduce UI to contribute to healthier aging.

Health Behaviors and Chronic Conditions Mediate the Protective Effects of Masculinity for Physical Performance in Older Adults

OBJECTIVE

We estimated the 2-year incidence of poor physical performance according to gender roles and examined mediating pathways related to health behaviors and chronic conditions.

METHOD

Data are from the International Mobility in Aging Study ( n = 1,676). The Bem Sex Role Inventory was used to classify participants into four gender roles as "masculine," "feminine," "androgynous," and "undifferentiated."

RESULTS

We found a higher incidence of poor physical performance among participants endorsing the feminine (adjusted incidence rate ratio [IRR] = 2.36, 95% confidence interval (CI) = [1.55, 3.60]) or the undifferentiated role (adjusted IRR = 2.19, 95% CI = [1.45, 3.30]) compared with the androgynous role. Smoking, physical activity, the number of chronic conditions, high body mass index, and depression were mediators of this association but not alcohol consumption.

DISCUSSION

This study provides evidence that gender roles are independently associated with physical performance. Health behaviors and chronic conditions are mediators of the relationship between gender roles and lower extremity physical function.
