What can we expect of health in old age?

Trends in mental health service utilisation by Australia's older population

OBJECTIVES

To examine the incidence, trends, and differences between age groups and sex in Medicare Benefits Schedule (MBS)-subsidised mental health service utilisation by older Australians over the past 10 years.

METHODS

A cross-sectional cohort study between 1 July 2009 and 30 June 2019 was conducted using publicly available MBS data for older individuals aged ≥65 years. Age- and sex-standardised yearly incidence rates of psychological therapy (MBS M06), GP mental health treatments (MBS A20), focussed psychological strategy (MBS M07), and psychiatric attendances (MBS A08) and incidence rate ratios (IRR) estimated using Poisson regression were calculated.

RESULTS

Overall, the rate of utilisation of primary care mental health services by the older population increased over the study period, with psychological therapy claims increasing the greatest from 14.4/1000 older persons in 2009/10 to 38.5/1000 in 2018/19 (IRR 1.11, 95% CI 1.09-1.13), followed by GP mental health treatments increasing from 43.7/1000 (95% CI 43.4-43.9) in 2009/10 to 81.0/1000 (95% CI 80.7-81.3) in 2018/19 (IRR 1.07/year, 95% CI 1.06-1.09). Females aged 65-74 years had the highest use of GP mental health treatments at 123.8/1000 compared to 63.6/1000 in males in 2018/2019.

CONCLUSIONS

While utilisation of mental health services by the older population in Australia has increased over the study period, it is important that policymakers and service providers continue to support access and use of these services, which may facilitate well-being and quality of life in the older population.

Impact of Social Isolation on Physical Functioning Among Older Adults: A 9-Year Longitudinal Study of a U.S.-Representative Sample

INTRODUCTION

Social isolation among older adults is associated with poor health and premature mortality, but its impact on physical functioning is not fully understood. Previous studies have typically relied on community samples, cross-sectional data, and suboptimal prospective designs. This study generates more robust evidence by investigating the longitudinal associations between social isolation and physical functioning in a large panel of older adults.

METHODS

Analyses were based on 9 waves of data (2011-2019) from a sample of adults aged ≥65 years from the U.S. National Health and Aging Trends Study (N=12,427 individuals; 54,860 person-year observations) and within-individual fixed-effect panel regression models. Analyses were conducted in 2020. Social isolation was measured using the Social Isolation Index, and physical functioning was measured through the Short Physical Performance Battery.

RESULTS

In fully adjusted fixed-effect regression models, each 1-unit increase in the Social Isolation Index resulted in an average decrease of 0.27 units in the Short Physical Performance Battery (95% CI= -0.31, -0.24). This relationship was moderated by age, with the Social Isolation Index bearing a significantly and substantially stronger influence on the Short Physical Performance Battery at older ages than at younger ages.

CONCLUSIONS

This study confirms that social isolation is associated with deficits in physical functioning among older adults in the U.S. using more robust data and methods than earlier studies. These findings highlight the importance of incorporating strategies to reduce social isolation in policies aimed at promoting successful aging.

The prevalence, trends and determinants of mental health disorders in older Australians living in permanent residential aged care: Implications for policy and quality of aged care services

OBJECTIVE

Mental health disorders are a major health concern in older people and are associated with a higher risk of disability, frailty and early mortality. This study aimed to conduct a contemporary population-based assessment of the prevalence, trends and factors associated with mental health disorders in individuals who are living in permanent residential aged care (PRAC) in Australia.

METHODS

A retrospective cross-sectional study was conducted using national data from the Registry of Senior Australians, a national cohort of older Australians who had aged care eligibility assessment and entered PRAC between 2008 and 2016. Stepwise multivariate logistic regression modeling was applied to identify factors associated with mental health disorders.

RESULTS

Of 430,862 individuals included in this study, 57.8% had at least one mental health disorder. The prevalence of depression, phobia/anxiety and psychosis were as follows: 46.2% (95% confidence interval = [46.0%, 46.3%]), 14.9% (95% confidence interval = [14.8%, 15.0%]) and 9.7% (95% confidence interval = [9.6%, 9.8%]), respectively. The likelihood of having a mental health disorder was higher for those who were (adjusted odds ratio [95% confidence interval]) relatively younger, specifically for every 10-year increment in age, the odds of having mental health disorders was 44.0% lower (0.56, [0.55, 0.56]); female (1.33 [1.32, 1.35]); having increasing numbers of physical health comorbidities, 6-10 (1.26 [1.24, 1.29]) or 11-15 (1.48 [1.45, 1.51]) or more than 15 (1.64 [1.58, 1.71]) compared to people having less than five comorbidities; having limitations related to health care tasks (1.05 [1.04, 1.07]), meals (1.04 [1.02, 1.05]) or social and community participation (1.10 [1.08, 1.12]).

CONCLUSION

The burden of mental health disorders in older Australians living in PRAC was high and individuals with these conditions tend to be younger, with several physical comorbidities and/or functional limitations. Understanding the profile of individuals with mental health disorders at entry into PRAC can be used as evidence for baseline resource allocation for this population and evaluation of future needs of mental health services.

Future trends in the prevalence of severe activity limitations among older adults in Europe: a cross-national population study using EU-SILC

OBJECTIVE

To project the proportion of population 65+ years with severe long-term activity limitations from 2017 to 2047.

DESIGN

Large population study.

SETTING

Population living in private households of the European Union (EU) and neighbouring countries.

PARTICIPANTS

Participants from the EU Statistics on Income and Living Conditions aged 55 years and older and living in one of 26 EU and neighbouring countries, who answered the health section of the questionnaire.

OUTCOME MEASURES

Prevalence of severe long-term activity limitations of particular subpopulations (ie, 55+, 65+, 75+ and 85+ years) by sex and country.

RESULTS

We find a huge variation in the prevalence of self-reported severe long-term limitations across Europe for both sexes. However, in 2017, about 20% of the female population aged 65 years and above and about 16% of their male counterparts are expected to report severe long-term activity limitations after accounting for differences in reporting. Accounting for cultural differences in reporting, we expect that European countries will have about 21% (decile 1: 19.5%; decile 9: 22.9%) of female and about 16.8% (decile 1: 15.4%; decile 9: 18.1%) of male 65+ years population with severe long-term activity limitations by 2047.

CONCLUSIONS

Overall, despite the expected increase of life expectancy in European countries, our results suggest almost constant shares of older adults with severe long-term activity limitations within the next 30 years.

Is it better to be happy or not depressed? Depression mediates the effect of psychological well-being on adverse health outcomes in older adults

OBJECTIVES

To examine the relationship between psychological well-being and depression in older adults and the relative contribution these psychological factors have on risk of functional disability, frailty, and mortality.

METHODS

This is a secondary analysis of 1668 community-dwelling older adults without dementia who participated in the second wave of the Canadian Study of Health and Aging. Baseline assessments of psychological well-being (Ryff scale) and depression (Geriatric Depression Scale; GDS) were collected. At 5-year follow-up, mortality data were collected; frailty and disability in activities of daily living were evaluated using the frailty index (FI) and the Lawton-Brody scale, respectively.

RESULTS

Area under the receiver-operating characteristic curve indicated that GDS and Ryff scores were able to independently discriminate whether individuals were considered frail (C = 0.66; C = 0.59, respectively), had limitations in basic (C = 0.64; C = 0.57, respectively) or instrumental (C = 0.70; C = 0.57, respectively) activities of daily living, or had died (C = 0.63; C = 0.57) at follow-up (all P < 0.01). Regression models in which the Ryff and GDS were included in the same model demonstrated that the GDS significantly predicted frailty, disability, and mortality, whereas the Ryff effect was not significant. Mediation analysis determined that the effect of psychological well-being on adverse outcomes was fully mediated by depression.

CONCLUSIONS

Our results suggest that although both depression and psychological well-being appear to modulate risk for adverse physical health outcomes, depression mediates this relationship. Detecting and treating depressive symptoms should be of high priority in older patients to mitigate risk of future physical health adversities including mortality.

Changes in the Lethality of Frailty Over 30 Years: Evidence From Two Cohorts of 70-Year-Olds in Gothenburg Sweden

Background

With aging, health deficits accumulate: people with few deficits for their age are fit, and those with more are frail. Despite recent reports of improved health in old age, how deficit accumulation is changing is not clear. Our objectives were to evaluate changes over 30 years in the degree of deficit accumulation and in the relationship between frailty and mortality in older adults.

Methods

We analyzed data from two population based, prospective longitudinal cohorts, assembled in 1971-1972 and 2000-2001, respectively. Residents of Gothenburg Sweden, systematically drawn from the Swedish population registry. The 1901-1902 cohort (N = 973) had a response rate of 84.8%; the 1930 cohort (N = 500) had a response rate of 65.1%. A frailty index using 36 deficits was calculated using data from physical examinations, assessments of physical activity, daily, sensory and social function, and laboratory tests. We evaluated mortality over 12.5 years in relation to the frailty index.

Results

Mean frailty levels were the same (x¯ = 0.20, p = .37) in the 1901-1902 cohort as in the 1930 cohort. Although the frailty index was linked to the risk of death in both cohorts, the hazards ratio decreased from 1.67 per 0.1 increment in the frailty index for the first cohort to 1.32 for the second cohort (interaction term p = .005).

Discussion

Although frailty was as common at age 70 as before, its lethality appears to be less. Just why this is so should be explored further.

[Organization of out-patient psychiatric care in dementia and cognitive impairment in aged. Part II: Clinical and economic efficacy of memory clinics and Alzheimer's disease centers]

The part II of the review is focused on a history of developing of memory clinics and Alzheimer's disease centers as well as on the indices of their activity in various countries and in Russia. Approaches to the evaluation of clinical and economic efficacy of new technologies of organization of care and a role of the national programs in solving of the problem of old age dementias were considered.
