The association of socio-economic factors with physical and mental capacity in elderly men and women

Association of housing adaptation services with the prevention of care needs level deterioration for older adults with frailty in Japan: a retrospective cohort study

BACKGROUND

Housing adaptations are aimed at minimizing the mismatch between older adults' functional limitations and their building environments. We examined the association of housing adaptations with the prevention of care needs level deterioration among older adults with frailty in Japan.

METHODS

The subjects comprised individuals who were first certified as having care support levels (defined as frail, the lowest two of seven care needs levels) under the public long-term care insurance systems between April 2015 and September 2016 from a municipality close to Tokyo. The implementation of housing adaptations was evaluated in the first six months of care support certification. Survival analysis with Cox proportional hazards model was performed to examine the association between housing adaptations and at least one care needs level deterioration, adjusting for age, sex, household income level, certified care support levels, cognitive function, instrumental activities of daily living, and the utilization of preventive care services (designed not to progress disabilities). We further examined the differences in the association of the housing adaptation amount by categorizing the subjects into the maximum cost group (USD 1,345-1,513) or not the maximum cost group (< USD 1,345). All the subjects were followed until the earliest of deterioration in care needs level, deaths, moving out of the municipality, or March 2018.

RESULTS

Among 796 older adults, 283 (35.6%) implemented housing adaptations. The incidence of care needs level deterioration was 19.3/1000 person-month of older adults who implemented housing adaptations, whereas 31.9/1000 person-month of those who did not. The adjusted hazard ratio (aHR) of care needs level deterioration was 0.69 (95% confidence interval (CI): 0.51-0.93). The aHRs were 0.51 (95% CI: 0.31-0.82) and 0.78 (95% CI: 0.57-1.07) in the maximum and not maximum cost groups, respectively.

CONCLUSIONS

Housing adaptations may prevent care needs level deterioration of older adults with frailty. Policymakers and health professionals should deliver housing adaptations for older adults at risk of increasing care needs.

Socioeconomic Status and Physical Functioning: A Longitudinal Study of Older Chinese People

Objectives

We aimed to assess the longitudinal associations of socioeconomic status and physical functioning using a large population-based survey data in China.

Method

We used four waves of the Chinese Longitudinal Healthy Longevity Survey (2002-2011). Physical functioning was assessed by activities of daily living (ADL) and instrumental activities of daily living (IADL) measures. Socioeconomic status was assessed using educational attainment, occupational status, household income, financial resources, and access to health services. Latent growth curve model combined with selection model was utilized.

Results

High education was not associated with the baseline level or the rate of change in ADL score but predicted better baseline IADL functioning. High income was related to better IADL functioning but had no effect on the rate of change in IADL. Inadequate financial resources and unavailability of health services were mainly associated with poorer ADL and IADL functioning at baseline. White-collar occupation was unrelated to the trajectory of physical functioning.

Discussion

This study provides no support either for the cumulative disadvantage or age-as-leveler theory. Improving financial status and accessibility of health care services, especially in lower social classes, may help to improve the overall level of physical functioning of the older adults.

Trajectories of limitations in activities of daily living among older adults in Mexico, 2001-2012

BACKGROUND

Trajectories of disability are an essential component to understand the burden of disability at the societal level. Longitudinal studies, compared to cross-national studies, enable a better analysis of the progression of physical limitations among the elderly. However, information on disability dynamics in developing countries is limited.

OBJECTIVES

This paper examines the changes in activities of daily living (ADLs) in an 11-yr. period in the Mexican elderly population aged 60 or older and identifies how sociodemographic variables alter these trajectories.

METHODS

The data come from the Mexican Health and Aging Study (MHAS), a national sample of adults born in 1951 or earlier, including a baseline survey in 2001 and follow-ups in 2003 and 2012.

RESULTS

The ADL score increased on average by 0.03 for every year respondents aged after 60. In contrast, the ADL score was reduced by 0.06 for every additional year of education.

CONCLUSIONS

Age, gender, and years of education were confirmed to influence the trajectories of ADL limitations. Understanding the patterns of deterioration of functional limitations will help public health policies to better serve the population.

Risk and protective factors for the development of chronic diseases in a rural elderly population in Rio Grande do Sul

Objective : to verify risk and protective factors for the development of chronic diseases among elderly persons living in the rural area of Linha Senador Ramiro, in Nova Bassano, Rio Grande do Sul. Methods: a cross-sectional censitary-based study was conducted of 70 male and female subjects aged 60 years or over. The subjects were interviewed through a questionnaire and anthropometrically evaluated (weight, height and waist circumference (WC)). The risk factors considered were: smoking, excess weight, intake of saturated fat, physical inactivity and excessive alcohol consumption. The protective factors were: physical activity during leisure time, consumption of fruits and vegetables, and cancer prevention. Results: the population was composed of 70 elderly persons, with a mean age of 70.4 ± 7.8 years. A total of 65.7% of the sample were women, 57.1% considered their health "normal", 72.3% said they were not sedentary and, among women, 78.3 and 47.8% performed mammography and Pap screening, respectively. The prevalence of excess weight was 55.9% and 76.5% of individuals were at increased risk of cardiovascular and metabolic diseases, according to waist circumference. Hypertension was the most prevalent chronic disease (64.3%). The prevalence of daily consumption of vegetables and fruit was 85.7% and 68.6%, respectively; wine, 54.3%, pork fat and queijo colonial (a local cheese) 75.7%, respectively, and homemade bread 87.1%. A total of 7.1% of the population said they smoked. Conclusions: the risk factors identified were high intake of saturated fat, excess weight and a high waist circumference. The protective factors were regular consumption of fruit and vegetables, low rates of physical inactivity and smoking, regular and moderate consumption of wine and preventive examinations. Further studies can assess the true association of these factors with the occurrence of cardiovascular and cerebrovascular events.

Autopercepção de saúde em idosos residentes em um município do interior do Rio Grande do Sul

Objetivo: Avaliar a percepção de saúde de idosos residentes em um município do interior do Rio Grande do Sul. Método: Estudo quantitativo, descritivo de corte transversal, onde foi aplicado um questionário sociodemográfico e clínico, em uma população de 274 idosos no período de agosto de 2011 a setembro de 2012. Resultados: Houve predominância do sexo feminino, na faixa etária dos 60-69 anos de idade, baixa renda e escolaridade. Em relação a patologias, 77,38% relataram possuir alguma doença associada, sendo a hipertensão a mais prevalente, acometendo 56,20% dos idosos, seguida da osteoartrite com 28,10%. Relataram ser etilistas 13,14% e tabagistas, 6,57%. Quanto à prática de atividade física, 67,52% relataram realizar atividade física de forma regular. Do total de idosos entrevistados, 47,81% consideraram sua saúde boa. Conclusão: Apesar de a maioria dos idosos ter referido boa saúde, grande número deles relatou ser portador de doenças crônicas, o que reforça a ideia de que a percepção de ser doente está mais relacionada às incapacidades do que a ser portador de danos crônicos.

Understanding Perceptions of Economic Status among Centenarians

Centenarians are often concerned with outliving their accumulated resources. Yet, research consistently finds that older adults, despite low incomes, are more financially satisfied than younger adults. This “satisfaction paradox” has been attributed to psychological accommodation to poor financial circumstances and lower expectations. As a result, scholars differentiate between objective levels of need and subjective perceptions. Missing is an understanding of whether feeling economically secure is associated with physical, mental, and/or psychological well-being and whether it varies by institutionalization status. This study examined data from 152 centenarians who participated in the first wave of the Iowa Centenarian Study. Analyses examined six perceived economic status variables (sufficiency of financial resources, ability to meet expenses, finances compared to others, meeting needs, ability to purchase extras, and having enough money for the future) and measures derived from activities of daily living, the Short Portable Mental Status Questionnaire (Pfeiffer, 1975) and the Geriatric Depression Scale (Yesavage, Brink, Rose, Lum, Huang, Adey, et al., 1983). Findings indicated that most centenarians do not feel able to handle their finances, yet believe that they are doing relatively well financially. Perceived economic status was positively associated with ability to complete daily living activities, cognitive ability, and psychological well-being with results differing by institutional status. In the end, we agree with other scholars that these relationships are rarely simple and require future exploration.

The disablement process: Factors associated with progression of disability and recovery in French elderly people

PURPOSE

To study the factors associated with progression, recovery and death from different grades of disability in elderly people.

METHOD

The sample included 3198 participants of the PAQUID ('Personnes Agées QUID') cohort, aged 65 and over and community-dwellers at baseline. Subjects were re-interviewed 1, 3, 5, 8 and 10 years after baseline. A five-state Markov model was used to estimate transition intensities between four grades of disability and toward death. We used a hierarchic scale of disability, which combines basic and instrumental activities of daily living and mobility. Several explanatory variables were investigated: medical, personal and environmental factors.

RESULTS

The factors associated with progression and/or no recovery of disability were cardiovascular diseases, stroke and diabetes, low cognition, visual impairment and dyspnoea (for pathologies and impairments), older age, female gender, low educational level (for risk factors), depression (for intra-individual factor) and being married, recent hospitalization and number of drugs (for extra-individual factors). Older age, male gender, tobacco consumption and living in an urban area were associated with mortality.

CONCLUSIONS

These findings confirm the independent contribution of each group of variables in the disablement process and stress their different impact on progression of disability or on recovery from different grades of disability.

Extent of social inequalities in disability in the elderly: results from a population-based study of British men

PURPOSE

Little is known about social inequalities in disability in the elderly. We examined the extent and determinants of socioeconomic inequalities in disability and functional limitation in elderly men in Britain.

METHODS

Disability was ascertained as problems with activities of daily living (ADLs) and instrumental ADL in a socioeconomically representative sample of 3,981 men from 24 British towns who were between 63 to 82 years of age in 2003. We also examined functional limitation. Measures of socioeconomic position were social class, age at leaving full-time education, and car and house ownership.

RESULTS

Men in lower social classes had greater risks of both ADL and instrumental ADL disability and functional limitation compared with higher social classes; odds ratios (95% CI) for social class V compared with I were 3.13 (1.64-5.97), 2.87 (1.49-5.51), and 2.65 (1.31-5.35), respectively. Behavioral risk factors (smoking, body mass index, physical activity) and particularly co-morbidity attenuated these differences; together, they reduced relative risks to 1.11 (0.49-2.51), 1.01 (0.45-2.25), and 1.05 (0.46-2.42). Age at leaving full-time education had no relation to functional limitations after taking social class into account. Men who were not house or car owners had greater odds of functional limitation and ADL disability compared with house or car owners, independent of behavioural risk factors, comorbidities and social class.

CONCLUSION

Strong socioeconomic inequalities in disability exist in the elderly, which were considerably explained by behavioral factors and comorbidity. Policy efforts are needed to reduce the social disparities in disability in the elderly.

Variation in biological status among Polish males and underlying socio-economic factors

The main purpose of this study was to evaluate the socio-economic and lifestyle factors associated with biological status of Polish men. Data were collected during a cross-sectional survey carried out in Poznań and several localities in Western Poland, between 2000 and 2002. The sample consisted of 2509 men ranging from 30 to 90 years of age. Biological status was expressed in terms of functional-biological age (BA) computed as a composite z-score of 11 biomarkers according to the method proposed by Borkan and Norris [1980a], and physiological reserve index (PR) developed by Goffauxet al.[2005]. The average biological age profiles (BAP) were compared in several subgroups of participants. The subgroups were categorized based on demographic, socio-economic and lifestyle characteristics. It was found that values of systolic and diastolic blood pressure, BMI, physical and emotional aging indicators and perceived satisfaction with life were significantly associated with most of the study factors, except for smoking habit and education level. The multivariate logistic regression models revealed that two factors, financial situation and physical activity, were significantly associated with the physiological reserve index estimation. The study confirmed the role of the socio-economic and lifestyle factors likely to play in men's biological status and aging rates.

Educational differences in mobility: the contribution of physical workload, obesity, smoking and chronic conditions

BACKGROUND

In earlier studies, determinants of socioeconomic gradient in mobility have not been measured comprehensively.

AIM

To assess the contribution of chronic morbidity, obesity, smoking and physical workload to inequalities in mobility.

METHODS

This was a cross-sectional study on 2572 persons (76% of a nationally representative sample of the Finnish population aged > or = 55 years). Mobility limitations were measured by self-reports and performance rates.

RESULTS

According to a wide array of self-reported and test-based indicators, persons with a lower level of education showed more mobility limitations than those with a higher level. The age-adjusted ORs for limitations in stair climbing were threefold in the lowest-educational category compared with the highest one (OR 3.3 in men and 2.9 in women for self-reported limitations, and 3.5 in men and 2.2 in women for test-based limitations). When obesity, smoking, work-related physical loading and clinically diagnosed chronic diseases were simultaneously accounted for, the educational differences in stair-climbing limitations vanished or were greatly diminished. In women, obesity contributed most to the differences, followed by a history of physically strenuous work, knee and hip osteoarthritis and cardiovascular diseases. In men, diabetes, work-related physical loading, musculoskeletal diseases, obesity and smoking contributed substantially to the inequalities.

CONCLUSIONS

Great educational inequalities exist in various measures of mobility. Common chronic diseases, obesity, smoking and workload appeared to be the main pathways from low education to mobility limitations. General health promotion using methods that also yield good results in the lowest-educational groups is thus a good strategy to reduce the disparities in mobility.

Influência dos fatores biopsicossociais sobre a capacidade funcional de idosos residentes no nordestes do Brasil

OBJETIVO: Analisar a influência dos fatores sociodemográficos, de saúde física e neuropsiquiátricos sobre a capacidade funcional de idosos residentes no município de Santa Cruz, Rio Grande do Norte, Brasil. MÉTODOS: Desenvolveu-se um estudo transversal, no qual uma amostra representativa de 310 idosos residentes na zona urbana da cidade de Santa Cruz-RN foi entrevistada, a partir da utilização de um questionário que continha informações sobre perfil sociodemográfico, condições de saúde física, função cognitiva e sintomatologia depressiva, além dos Índices de Katz e Lawton, que mediram as atividades básicas (ABVD's) e instrumentais (AIVD's) da vida diária. A análise estatística foi feita mediante análise bivariada (Qui-quadrado de Pearson), seguida de regressão logística binária na análise multivariada, com a respectiva odds ratio (OR), considerando nível de significância p< 0,05 e intervalo de confiança (IC) de 95%. RESULTADOS: Para o Índice de Katz teve-se que 86,9% eram independentes e no Índice de Lawton apenas 47,4%. Na análise multivariada houve associação com as ABVDs a idade (OR= 1,06) e má percepção de saúde (OR= 3,64). Nas AIVD's houve associação com a idade (OR= 1,18), sexo feminino (OR= 4,30), analfabetismo (OR= 3,78), estado civil (OR= 2,14), sintomatologia depressiva (OR= 4,54) e a má percepção de saúde (OR= 4,47). CONCLUSÃO: As variáveis associadas à incapacidade funcional revelam uma complexa relação entre o estado de saúde dos idosos e possíveis fatores de risco de declínio físico.

Feeling hindered by health problems and functional capacity at 60 years and above

It is common to use activities of daily living (ADL) rating scales to identify the impact of health problems such as diseases, impaired eyesight or hearing on daily life. However, for various reasons people with health problems might feel hindered in daily life before limitations in ability to perform ADL have occurred. In addition, there is sparse knowledge of what makes people feel hindered by health problems in relation to their ADL capacity. The aim was to investigate feeling hindered by health problems among 1297 people aged 60-89 living at home in relation to ADL capacity, health problems, life satisfaction, self-esteem, and social and financial resources, using a self-reported questionnaire, including questions from Older Americans' Resources and Services schedule (OARS), Rosenberg's self-esteem and Life Satisfaction Index Z (LSIZ). People feeling greatly hindered by health problems rarely had anyone who could help when they needed support, had lower life satisfaction and self-esteem than those not feeling hindered. Feeling hindered by health problems appeared to take on a different meaning depending on ADL capacity, knowledge that seems essential to include when accomplishing health promotion and rehabilitation interventions, especially at the early stages of reduced ADL capacity.

Trends and educational disparities in functional capacity among people aged 65-84 years

BACKGROUND

This study examined 10 year trends in functional capacity by gender, age, and education among elderly Finns aged 65-84 years, focusing on difficulties in basic activities of daily living (BADL). Educational disparities and their trends in the prevalence of these difficulties were also assessed.

METHODS

Data were derived from nationally representative monitoring surveys conducted biennially from 1993 to 2003 by the National Public Health Institute (KTL). A total of 5740 men and 5746 women were included in the study (response rate 80%). Activities of daily living (ADL) measures were used to assess levels of functional capacity. Education was divided into two groups: low (0-8 years) and high (9+ years). Age-adjusted trends and logistic regression analyses were computed.

RESULTS

A clear downward trend in BADL difficulties was observed in all age groups in both genders. 80-84 year olds had clearly poorer functional ability than 65-69 year olds, even when adjusted for chronic diseases. Despite the overall improvement in functional capacity in both educational groups, low educational status persistently predicted poorer functional capacity. When chronic diseases and survey period were controlled for, the educational disparities attenuated slightly but remained significant.

CONCLUSIONS

The number of Finnish elderly with BADL difficulties has declined markedly over the past 10 years. However, persistent educational disparities continue to present a challenge to public health initiatives for reducing inequalities in health.

Prevalência e fatores associados à sintomatologia depressiva em idosos residentes no Nordeste do Brasil

OBJETIVO: Analisar a influência de fatores sociodemográficos, de saúde física, capacidade funcional e função cognitiva sobre a sintomatologia depressiva de idosos do município de Santa Cruz, no Rio Grande do Norte. MÉTODOS: Estudo com delineamento transversal de base populacional, incluindo 310 idosos, acima de 60 anos, residentes na zona urbana da cidade, nos quais se aplicou a Escala de Depressão Geriátrica (GDS-15).Aanálise estatística foi realizada com nível de significância p = 0,05, com cálculo da respectiva odds ratio (OR) na regressão logística binária. RESULTADOS: Encontrou-se uma prevalência de 25,5% de sujeitos considerados casos de depressão, nos quais, a partir de análise multivariada, verificou-se associação significativa com idade acima de 75 anos (p = 0,046), analfabetismo (p = 0,037), má percepção de saúde (p < 0,001) e dependência para atividades instrumentais da vida diária (AIVD) (p = 0,001). CONCLUSÕES: As variáveis idade acima de 75 anos, analfabetismo, má percepção de saúde e dependência para AIVD estiveram associadas de forma independente à presença de sintomatologia depressiva nos idosos da nossa população. Os autores discutem que a identificação de fatores que influenciam o surgimento de sintomas depressivos em idosos constitui passo fundamental para o planejamento das ações que visem reduzir os efeitos dessa enfermidade na qualidade de vida dessas pessoas.

Oral infections as predictors of mortality

OBJECTIVE

Oral infections may increase the levels of cytokines in the blood which, in turn, are associated with early mortality in the elderly. We investigated the possible association between oral infections and mortality.

DESIGN

Prospective cohort study over a 5-year follow-up.

SETTING

Research laboratory.

PARTICIPANTS

A cohort born in 1910 (n = 94) was examined in the year 1995. Five years later mortality data were obtained from the population register for 49 deceased subjects.

MAIN OUTCOME MEASURES

Urgent need of dental treatment, lifetime, erythrocyte sedimentation rate (ESR).

RESULTS

The multivariate analysis adjusted for general health and lifestyle factors showed that the risk for death of subjects in urgent need of dental treatments was 3.9 times higher than that of the other subjects. Among men ESR correlated significantly with urgent need of dental treatment.

CONCLUSIONS

Oral infections among frail elderly people may be a sign of early mortality.

The impact of socio-economic factors on functional status decline among community-dwelling older adults in China

The purpose of this paper is to examine the impact of baseline socio-economic factors on functional status decline over a period of 3 years among a sample of Chinese older men and women, using the China Health and Nutrition Surveys of 1997 and 2000. In addition, the study tries to determine whether risk differentials by these socio-economic factors can be explained by other demographic, health-related and nutritional risk factors. The eligible study population was defined as women and men aged 55 years and over who at baseline were free from any form of disablement in activities of daily living (ADLs) or instrumental activities of daily living (IADL) tasks. Among subjects with complete data at followed-up (N = 976), the overall incidence proportions of any functional status decline, IADL only and ADL declines were 25.8%, 18.9% and 6.9%, respectively. Our study found that education is strongly and inversely associated with incidence of combined functional status decline and IADL only but not with the onset of ADL disability. Similarly, household income per capita was inversely associated with functional status decline and IADL disability incidence, with a clear dose-response relationship, even after adjustment for age and gender. However, multivariate analysis demonstrated that the latter association was highly confounded by other demographic factors, especially urban-rural area of residence. Using a combined measure of socio-economic status that includes years of education and household income per capita, the age and gender-adjusted odds ratio for functional status decline and belonging to lower SES class as compared to middle, upper middle and upper classes was 3.82 (95% CI: 2.15, 6.77) and 2.77 (95% CI: 1.52, 5.03) after further adjustment for urban-rural area of residence and living arrangements. Hence, there are wide socio-economic disparities in the functional health of older adults in China, although such disparities are more seen for IADL decline and are almost exclusively attributed to differentials in educational attainment. Finally, nutritional and health-related risk factors do not seem to act as intermediate factors in this association and hence further research should try to uncover other mechanisms by which SES affects changes in functional health among older adults in China.

Changes in dental status over 10 years in 80-year-old people: a prospective cohort study

OBJECTIVES

The aim of the present study was to follow-up the condition of the teeth over a sufficiently long period.

METHODS

Dental examinations were a part of a multidisciplinary 10-year cohort study on the elderly. These examinations were made in 1990 (n = 226), 1995 (n = 90) and 2000 (n = 65) for the entire population born in 1910 and living in Jyväskylä, Finland. The subjects were divided into two categories, dentate (one tooth or more) and edentulous.

RESULTS

The results showed that men had more intact teeth and lower DMF scores than women, but the differences diminished during the follow-up period. The number of remaining and filled teeth of those women who took part in all three phases of the present study was higher than that of those who died during the follow-up. In men the DMF scores showed the opposite trend. The most significant deterioration during the 10-year follow-up was found in the number of teeth and DMF scores in men and in the number of remaining and filled teeth in women.

CONCLUSION

Among men, in particular, significant changes in oral health status could be seen even between 80 and 90 years of age. Hence, regardless of advanced age, a subject should be motivated by the oral health care team to seek regular dental treatment.

Association of quality of life in old age in Britain with socioeconomic position: baseline data from a randomised controlled trial

STUDY OBJECTIVE

To identify socioeconomic differentials in quality of life among older people and their explanatory factors.

DESIGN

Baseline data from a cluster randomised controlled trial of the assessment and management of older people in primary care. Outcome measures were being in the worst quintile of scores for, respectively, the Philadelphia geriatric morale scale and four dimensions of functioning from the sickness impact profile (home management, mobility, self care, and social interaction).

SETTING

23 general practices in Britain.

PARTICIPANTS

People aged 75 years and over on GP registers at the time of recruitment, excluding those in nursing homes or terminally ill. Of 9547 people eligible, 90% provided full information on quality of life and 6298 also did a brief assessment.

RESULTS

The excess risk of poor quality of life for independent people renting rather than owning their home ranged from 27% for morale (95% CI 9% to 48%) to 62% for self care (95% CI 35% to 94%). Self reported health problems plus smoking and alcohol consumption accounted for half or more of the excess, depending on the outcome. Having a low socioeconomic position in middle age as well as in old age exacerbated the risks of poor outcomes. Among people living with someone other than spouse the excess risk from renting ranged from 24% (95% CI -10% to 70%) for poor home management to 93% (95% CI 30% to 180%) for poor morale.

CONCLUSIONS

Older people retain the legacy of past socioeconomic position and are subject to current socioeconomic influences.
