A comparison of health expectancies over 10 years: implications for elderly service needs in Hong Kong

Non-Communicable Diseases, Longevity, and Health Span: A Hong Kong Perspective

The health of different countries evolves in parallel with their economic development. Communicable diseases play a more prominent role in low-income countries compared with high-income countries, while non-communicable diseases (NCDs) have become dominant in developing and developed economies. This transition has been accompanied by public health efforts to prevent NCDs, resulting in improvements in total life expectancy at birth (TLE). It is recognized that health determinants are not confined to healthcare systems, but that social determinants play a key role in health inequalities. The rapid increase in life expectancy at birth has led to increasing numbers of older adults, where health inequalities are accentuated. The current UN Decade of Healthy Aging calls for a life-course approach to building intrinsic capacity, maintaining function, and avoiding dependency with age instead of avoiding mortality and morbidity. TLE in Hong Kong is one of the highest in the world as a result of public health preventive efforts and an essentially free hospital system. However, the increase in TLE has not been accompanied by the same magnitude of increase in health span, resulting in an increasing dependency burden. Geography, culture, dietary and smoking habits, physical activity, urban planning, and neighbourhood cohesion are some of the social determinants affecting TLE and also health inequalities. With population ageing, it would be appropriate to focus on the social determinants affecting health span to maintain functional independence rather than prolonging life. A whole-of-society response instead of relying solely on the adaptation of health and social care systems would be needed, together with more nuanced metrics to measure health span.

Secular trends of life expectancy and disability-free life expectancy at age 65 and associated gender and area-level socioeconomic inequalities in Hong Kong: a serial cross-sectional study between 2007 and 2020

Background

Despite Hong Kong's world leading longevity, little is known about its associated disability burden and social patterning. Hence, this study assessed the gender-specific secular trends and area-level inequalities in life expectancy (LE) and disability-free life expectancy (DFLE) at age 65 in Hong Kong.

Methods

Population structure, death records, and disability data in 2007, 2013, and 2020 were retrieved from the Census and Statistics Department to estimate LE and DFLE using the Sullivan Method. District-based sociodemographic indicators were used to compare LE and DFLE across 18 districts of Hong Kong in 2013.

Findings

Between 2007 and 2020, LE at age 65 increased by 3.7 years (from 18.3 to 22.0) in men and by 2.1 years (from 22.7 to 24.8) in women. By contrast, DFLE increased more slowly, by 1.8 years (from 14.6 to 16.3) in men and by only 0.1 year (from 16.4 to 16.5) in women, leading to a substantial increase in proportion of life spent with disability. Results from multiple linear regression using district-based data in 2013 showed a similar extent of associations of education with LE and DFLE (mean year difference: 0.81 [95% CI: 0.14, 1.48] and 0.68 [0.10, 1.27], respectively, per 10% increase in average education level), while female gender was more strongly associated with LE (4.44 [3.56, 5.31]) than with DFLE (2.00 [1.18, 2.82]).

Interpretation

Expansion of disability burden and male-female health-survival paradox hold true in Hong Kong. Unlike Western countries with a stronger socioeconomic patterning of DFLE, the extent of area-level socioeconomic inequalities in LE and DFLE appears to be more comparable in Hong Kong.

Evolutionary game and stability analysis of elderly care service quality supervision from the perspective of government governance

Objective

The performance of government functions is an important guarantee for the standardized operation of the elderly service market. The objective of this study is to explore the optimal path for the government to govern the elderly care service market.

Methods

The tripartite evolutionary game model is proposed in the paper, which composed of local governments, private elderly care institutions and the public. Furthermore, three mechanisms, i.e. dynamic penalty and static subsidy, static penalty and dynamic subsidy, dynamic penalty and dynamic subsidy, are designed. Under these different mechanisms, the stability of each subject's strategy choice is analyzed by using system dynamics simulation.

Results

The introduction of dynamic mechanisms can compensate for the inability of static mechanisms to bring the system to a steady state. The dynamic penalty and dynamic subsidy mechanism allows the system to evolve to the desired point of stability. The self-discipline behavior of private elderly care institutions is positively correlated with penalties and reputation gains-losses, negatively correlated with subsidies, and not correlated with supervision rewards. Excessive subsidies will promote the collusion of private elderly institutions.

Conclusion

Only when the local government adopts the dynamic penalty and dynamic subsidy mechanism will private elderly care institutions choose to operate in a fully self-disciplined manner. Reasonable adjustments of penalties, reputation gains-losses and subsidies can not only further optimize the dynamic penalty and dynamic subsidy mechanism, but also help to achieve diversified regulatory objectives of the government. This study would provide a reference for local governments seeking to develop effective regulatory policies for the elderly service market.

Healthy Ageing Should Be a Key Component of Ageing in Place: Case Study from Hong Kong

As part of a knowledge-transfer project consisting of a series of three talks on the topic of healthy ageing and ageing in place, we explored what participants (older adults, students, the general public, as well as professionals in architecture, urban planning and property management) consider to be key requirements for ageing in place and healthy ageing. Feedback is captured using survey questionnaires and a post-talk discussion group. Safety, a comfortable and spacious environment, age-friendly facilities and meeting the needs of older adults, the availability of caring support and home maintenance services were the most frequently mentioned desirable features of ageing in place. Future models for different types of support for ageing in place may be explored by management companies working with the residents themselves, to develop a sustainable business model.

Mitigating inequalities in community care needs of older adults with dementia: a qualitative case study of an integrated model of community care operated under the proportionate universalism principle

Background

Population ageing and community care on older adults, as well as the marked social inequalities in health, have received growing concern by the government and the community. This study evaluated the medico-social integrated day care model of the Cadenza Hub for older adults with dementia. We also examined whether services subsidized by the publicly funded graded financial support of the Community Care Service Voucher for the Elderly (CCSV) could mitigate social inequalities in community care needs, from the perspective of the caregivers.

Methods

In this qualitative case study, we adopted purposeful sampling strategy to recruit 14 caregivers of active day care service users with dementia, with different socioeconomic background and duration of service use, for face-to-face semi-structured in-depth interviews between June and August 2021. The transcribed data were closely read to capture key themes using thematic analyses.

Results

Caregivers faced tremendous caregiving burden in the absence of community care support and struggled in choosing care services. Most informants benefited from the day care service, whereas the financial support of CCSV was crucial to ensure equitable access to community care. Non-governmental organizations and social workers were the key to bridging the information gap.

Conclusion

The integrated day care of the Cadenza Hub appeared to have addressed the unmet needs of older adults with dementia and their caregivers, including the socioeconomically disadvantaged with the CCSV support. The community care service delivery model might be applicable to address other health inequalities problems.

Trends over two decades in life expectancy with complex health problems among older Swedes: implications for the provision of integrated health care and social care

BACKGROUND

Due to population aging, it is essential to examine to what extent rises in life expectancy (LE) consist of healthy or unhealthy years. Most health expectancy studies have been based on single health measures and have shown divergent trends. We used a multi-domain indicator, complex health problems (CHP), indicative of the need for integrated medical and social care, to investigate how LE with and without CHP developed in Sweden between 1992 and 2011. We also addressed whether individuals with CHP more commonly lived in the community in 2011 compared to earlier years.

METHODS

CHP were defined as having severe problems in at least two of three health domains related to the need for medical and/or social care: symptoms/diseases, cognition/communication, and mobility. The Swedish Panel Study of Living Conditions of the Oldest Old (SWEOLD), a nationally representative survey of the Swedish population aged ≥ 77 years with waves in 1992, 2002 and 2011 (n≈2000), was used to estimate the prevalence of CHP. Age- and gender-specific death rates were obtained from the Human Mortality Database. The Sullivan method was deployed to calculate the remaining life expectancy with and without CHP. The estimates were decomposed to calculate the contribution of changes from morbidity and mortality to the overall trends in LE without CHP.

RESULTS

Between 1992 and 2011, both total LE (+ 1.69 years [95% CI 1.56;1.83] and LE without CHP (+ 0.84 years [-0,87;2.55]) at age 77 increased for men, whereas LE at age 77 increased for women (+ 1.33 [1.21;1.47]) but not LE without CHP (-0.06 years [-1.39;1.26]). When decomposing the trend, we found that the increase in LE with CHP was mainly driven by an increase in the prevalence of CHP. Among individuals with CHP the proportion residing in care homes was lower in 2011 (37%) compared to 2002 (58%) and 1992 (53%).

CONCLUSIONS

The findings, that an increasing number of older people are expected to live more years with CHP, and increasingly live in the community, point towards a challenge for individuals and families, as well as for society in financing and organizing coordinated and coherent medical and social services.

Age and Ageing journal 50th anniversary commentary seriesHealthcare for older people in Asia

Populations in Asian developed economies are rapidly ageing, such that, currently, Hong Kong and Japan have the longest life expectancy at birth for both men and women. However, extended lifespan is not necessarily accompanied by prolongation of health span, such that there is increasing prevalence of frailty and dependency, which translates into increase in complex health and social needs as well as increase in absolute numbers of older adults that require such needs. Consideration of social determinants of healthy ageing would be important in the design of equitable health and social care systems. There is a trend towards development of integrated medical social care in the community in Asian countries. Long-term care insurance and also philanthropic support play a role in the financing of such care models.

Factors Affecting Trends in Societal Indicators of Ageing Well in Hong Kong: Policies, Politics and Pandemics

OBJECTIVES

To document the trend in a quality of life indicator for the older Hong Kong population as an assessment of the impact of age friendly city policies, political conflicts and the covid-19 pandemic.

DESIGN

Random telephone survey and collection of government data over four years (2017-2020).

SETTING

Community living older people.

PARTICIPANTS

People aged 50 years and over.

MEASUREMENTS

The Hong Kong Quality of Life Index covering four domains of in income security, health status, capability and enabling environment.

RESULTS

From 2017-9, improvements were seen in various domains in parallel with the adoption of the World Health Organization's Age Friendly City concept by government policy together with a territory wide initiative supported by a major philanthropic organization. However scores of all domains dropped markedly as a result of political conflicts as well as the onset of the pandemic.

CONCLUSION

The documentation of the trend in HKEQOL shows that while it may be used as a macro indicator that is able to reflect policies affecting the well-being of older people, it is also able to reflect the impact of societal unrest and pandemics, and that the latter may override the effect of existing ageing policies. It also follows that during social unrest and pandemics, specific policies targeting older people may be needed to maintain well-being.

Does the Abbreviated Mental Test Accurately Predict Cognitive Impairment in Thai Older Adults? A Retrospective Study

The Abbreviated Mental Test is a screening tool for cognitive impairment in older adults now used in Thailand's annual national cognitive assessment required for all community-dwelling older adults in Thailand, however its validity has not been established for this purpose. This retrospective study evaluated the results of this abbreviated test as well as the Mini Mental State Examination, in a sample of older adults who participated in the national cognitive assessment in 2018 in Udon Thani Province, Thailand. Of the 174,227 cases, 1518 cases had scores on both tests. The Mini-Mental State Examination is performed on a select group of individuals who scored low on the initial and briefer test. Results indicated that the proportion of cognitive impairment as defined by the Abbreviated Mental Test (87.7%) was five times higher than indicated by the more rigorous Mini-Mental State Examination (16.3%). At the AMT standard cut point of 8 out of a total possible score of 10 for the presence of cognitive impairment, sensitivity was low (12.8%) but specificity was high (90.3%), while the optimal cut-point of 5 on the Receiver Operating Characteristic Curve errs on the side of being highly sensitive but not specific enough to screen for cognitive impairment. Additionally, one item on the AMT was answered incorrectly by 95% of responders. Although brief and easy to administer, the AMT may be a suboptimal choice for screening for cognitive impairment. When administered by volunteer health workers, the AMT may also possess limited reliability and validity. Cognitive screening administered by nurses should be considered to help detect cognitive impairment older adults dwelling in the community.

A research agenda for ageing in China in the 21st century (2nd edition): Focusing on basic and translational research, long-term care, policy and social networks

One of the key issues facing public healthcare is the global trend of an increasingly ageing society which continues to present policy makers and caregivers with formidable healthcare and socio-economic challenges. Ageing is the primary contributor to a broad spectrum of chronic disorders all associated with a lower quality of life in the elderly. In 2019, the Chinese population constituted 18 % of the world population, with 164.5 million Chinese citizens aged 65 and above (65+), and 26 million aged 80 or above (80+). China has become an ageing society, and as it continues to age it will continue to exacerbate the burden borne by current family and public healthcare systems. Major healthcare challenges involved with caring for the elderly in China include the management of chronic non-communicable diseases (CNCDs), physical frailty, neurodegenerative diseases, cardiovascular diseases, with emerging challenges such as providing sufficient dental care, combating the rising prevalence of sexually transmitted diseases among nursing home communities, providing support for increased incidences of immune diseases, and the growing necessity to provide palliative care for the elderly. At the governmental level, it is necessary to make long-term strategic plans to respond to the pressures of an ageing society, especially to establish a nationwide, affordable, annual health check system to facilitate early diagnosis and provide access to affordable treatments. China has begun work on several activities to address these issues including the recent completion of the of the Ten-year Health-Care Reform project, the implementation of the Healthy China 2030 Action Plan, and the opening of the National Clinical Research Center for Geriatric Disorders. There are also societal challenges, namely the shift from an extended family system in which the younger provide home care for their elderly family members, to the current trend in which young people are increasingly migrating towards major cities for work, increasing reliance on nursing homes to compensate, especially following the outcomes of the 'one child policy' and the 'empty-nest elderly' phenomenon. At the individual level, it is important to provide avenues for people to seek and improve their own knowledge of health and disease, to encourage them to seek medical check-ups to prevent/manage illness, and to find ways to promote modifiable health-related behaviors (social activity, exercise, healthy diets, reasonable diet supplements) to enable healthier, happier, longer, and more productive lives in the elderly. Finally, at the technological or treatment level, there is a focus on modern technologies to counteract the negative effects of ageing. Researchers are striving to produce drugs that can mimic the effects of 'exercising more, eating less', while other anti-ageing molecules from molecular gerontologists could help to improve 'healthspan' in the elderly. Machine learning, 'Big Data', and other novel technologies can also be used to monitor disease patterns at the population level and may be used to inform policy design in the future. Collectively, synergies across disciplines on policies, geriatric care, drug development, personal awareness, the use of big data, machine learning and personalized medicine will transform China into a country that enables the most for its elderly, maximizing and celebrating their longevity in the coming decades. This is the 2nd edition of the review paper (Fang EF et al., Ageing Re. Rev. 2015).

Are We Living Longer and Healthier?

Objective: To examine whether we live healthier as we live longer in Hong Kong, which has one of the highest life expectancies in the world. Methods: Sullivan's method was used to evaluate the chronic disease-free life expectancy (CDFLE), life expectancy in good self-perceived health (GPHLE), and impairment-free life expectancy (IFLE) among population aged 50 years and older in Hong Kong in 2007-2016. Results: In spite of the marked improvement in life expectancy in Hong Kong, the increase in GPHLE was much smaller, while CDFLE and IFLE even declined for both genders. The situation was more severe among older population. Discussion: People in Hong Kong live longer but with worsening health. The expansion of chronic diseases, self-perceived poor health, and impairments among older adults calls for more fiscal investments, government attention, and public health policies.
