Physical Activity and Social Support to Promote a Health-Promoting Lifestyle in Older Adults: An Intervention Study

The purpose of this study was to understand the effect of intervention in the form of physical activity and social support while co-exercising to promote a health-promoting lifestyle in older adults. This study openly recruited 60 healthy male older adults, all of whom wore a wrist-worn Garmin device walker. Experimental group A was monitored by a special person and walked together as a group, experimental group B walked independently outdoors, and the control group went about their daily routine as normal. All participants recorded daily steps and calorie consumption data for eight weeks. The results of the study showed that when walking together in experimental group A, the number of daily walks and calories consumed could be maintained at a high level due to the effect of group and social support. The number of daily walks in experimental group B was inconsistent due to the lack of motivation to walk on their own. The control group consumed the lowest number of calories in their daily routine. The results show that physical activity and social support have positive explanatory power for a health-promoting lifestyle. Finally, physical activity in older adults should be promoted, and social support for interaction with peers can effectively promote a healthy lifestyle and respond to the arrival of the super-aged society in advance.

Toward the development of a vibrant, super-aged society: The future of medicine and society in Japan

BACKGROUND

As Japan's population continues to age, it is estimated that the number of people aged ≥75 years will exceed 20 million by 2025. Furthermore, over the past 10 years, we have not reduced the difference between life expectancy and healthy life expectancy. Therefore, the extension of healthy life expectancy and the development of a healthy society are the most urgent issues. In terms of medical care, the changing times have inevitably led to changes in disease structures and medical demands; therefore, the medical delivery system has had to be changed to meet these demands. As dementia rapidly increases, it is important to address "frailty," a condition in which people become more vulnerable to environmental factors as they age, and there is a need to provide services to older people, particularly the old-old, that emphasize quality of life in addition to medical care. To realize a super-aged society that will remain vigorous and vibrant for many years, we need to rethink the future of Japanese medicine and healthcare, and the state of society.

CURRENT SITUATION AND PROBLEMS

Disparity between healthy life expectancy and average life expectancy in the realization of a healthy society It is a challenge to build a society with a long and healthy life expectancy through comprehensive prevention and management of lifestyle-related diseases, as well as the elucidation of the factors that explain sex differences in healthy life expectancy, based on the recognition that lifestyle-related diseases in midlife are risk factors for frailty and dementia in old age. Challenges in medical care for building a super-aged and healthy society The challenges include promoting clinical guidelines suitable for older people, including lifestyle-related disease management, promoting comprehensive research on aging (basic research, clinical research and community collaboration research), and embodying a paradigm shift from "cure-seeking medical care" to "cure- and support-seeking medical care." Furthermore, the key to the future of integrated community care is the development of a comprehensive medical care system for older people in each region and the development of the next generation of medical personnel. Dissemination of frailty prevention measures in a super-aged society The concept of frailty encompasses the meaning of multifacetedness and reversibility; therefore, a comprehensive approach is required, including the renewal of conventional prevention activities in each region, such as the nutritional status of older people, physical activity including exercise, and various opportunities for social participation and participation conditions. Challenges of an unstable diet and undernutrition in older people According to the National Health and Nutrition Examination Survey of Japan, energy and protein intakes are low in Japanese people aged ≥75 years; particularly in people aged ≥80 years, low and insufficient intake of nutrients are prominent. Undernutrition in older people is increasing and is more pronounced in women. There are multiple factors behind this, including social factors, such as living alone, eating alone, poverty and other social factors, as well as problems with access to food security. Pharmacotherapy for older people: measures against polypharmacy In addition to the problems of adverse drug events, drug interactions, duplication of effects and the presence of drugs that "require particularly careful administration," it is also necessary to take measures against polypharmacy in older people, as well as medical economic issues, such as high drug costs and large amounts of remaining drugs. Barriers to this measure include multiple medical institution visits for each disease, lack of coordination between professions, and lack of understanding by patients and families. Role of local communities in a healthy society The decline in the working-age population is also a major challenge; however, we need to make a shift to use this declining birthrate and aging population as an opportunity rather than a crisis. As we look ahead to the coming of the 100-year age of life, we rethink the creation of a comprehensive society and community, and aim to create an age-free society where everyone can play an active role and live in peace, regardless of age.

CONTENTS OF THE PROPOSAL

In this report, we have put together a vision for the future of an aging Japanese society from a broader perspective of how the environment and local communities should be, rather than simply from the perspective of individual health. We aim to convey this proposal to the Ministry of Health, Labor and Welfare, the Ministry of Education, Culture, Sports, Science and Technology, the Cabinet Office, and various professional organizations. The paradigm shift from "cure-seeking medical care" to "cure- and support-seeking medical care" should be promoted for the development of a healthy society While further promoting pre-emptive medical care in the medical care for older people, the development of multidisciplinary medical guidelines appropriate for older people should be promoted at the same time. In addition, we should promote basic aging research, clinical research (including the long-term care field) and transitional research that cover regional areas. Furthermore, while promoting the paradigm shift from "cure-seeking medical care" to "cure- and support-seeking medical care," the development of various comprehensive medical treatment systems for older people and the strengthening of integrated community care systems should be promoted. Development of the next generation of medical personnel to comprehensively deal with geriatric care, including training geriatric specialists, should be promoted As the number of older people with multimorbidities and frailty rapidly increases in the future, we should promote the development of the next generation of medical personnel who can comprehensively handle medical care for older people, including training leading geriatricians in cooperation with multiple professions in the integrated community care system to provide sufficient medical care. Countermeasures for frailty in older people should be promoted from medical and community planning perspectives To address frailty, which requires comprehensive evaluation and intervention, the three pillars of frailty prevention (nutrition, exercise and social participation) should be incorporated and addressed as part of community development within each municipality, taking into account local characteristics. In particular, it is necessary to revise the way of thinking about nutrition management in older people and the guidelines of the societies in the field. In addition, it is important to strengthen industry-academia-government-private partnerships in each region, taking into account not only medical issues, but also social factors, and encourage the development of momentum in the entire region regarding measures against undernutrition in older people. Polypharmacy measures should be promoted in pharmacotherapy for older people It is necessary to promote cooperation between physicians and pharmacists, establish other multiprofessional cooperation systems, and develop medical and long-term care insurance systems to support this. It is also essential to change the public's mindset, and awareness-raising activities at all levels are required, including the enhancement of educational materials for medical caregivers and the general public. In addition, the economic impact of healthcare using big data should be timely clarified. Innovation in medical and urban planning perspectives should be promoted In the future, it will be necessary to modify and update multidisciplinary approaches such as social participation (e.g. participation in a salon) with a view to innovation in both medical care and community development, especially on the idea of a symbiotic community. In addition, industry-academia-government-private partnership is necessary, including all aforementioned, such as places where people can play an active role in the rest of their lives (such as employment), promotion of human connections, promotion of technology to support older people and support for daily life.

The community-based integrated care system in Japan: Health care and nursing care challenges posed by super-aged society

Japan is experiencing unprecedented aging of its population. People age 65 years or older accounted for 28.1% of the total population in 2018, and that proportion is expected to reach 33.3% in 2036 and 38.4% in 2065. In 2017, the average life expectancy in Japan was 81.09 years for men and 87.26 years for women. By 2065, it is expected to reach 84.95 years for men and 91.35 years for women. Population aging affects health and long-term care systems. The government proposed the establishment of "a community-based integrated care system" by 2025 with the purpose of comprehensively ensuring the provision of health care, nursing care, preventive care, housing, and livelihood support. This will require health care and nursing care professionals who are capable of fully understanding the physical and mental characteristics of elderly people and the fostering of organic collaboration with others professionals in the community-based integrated care system. A department of gerontology or geriatric medicine is desired to be established in each medical school to teach students medicine and efficient medical care, to conduct research, and to develop personnel to facilitate this paradigm shift. In 2018, there were 263 colleges of nursing with an admissions capacity of 23,667. In Japan, Certified Nurse Specialists can specialize in 13 areas as of December 2016. The number of Certified Nurse Specialists increased to 2,279 as of December 2018. One hundred and forty-four of those specialists specialized in Gerontological Nursing while 53 specialized in Home Care Nursing. The number of nurses specializing in Gerontological Nursing and Home Care Nursing is desired to be increased in order to implement and improve community-based comprehensive care.

Progression of hearing loss and choice of hearing aids by patients in their 60s, 70s, and 80s and older: experience in the Japanese super-aged era

Background: Demographic data of patients with sensorineural hearing loss (SNHL) in super-aged societies are still limited.Aims/objectives: To report audiometric statistics of SNHL and hearing aid (HA) use in patients in their 60s, 70s, and 80s and older during the super-aged era.Material and methods: Medical charts and audiograms of 2064 older patients with SNHL who visited a Japanese University Hospital in 2007-2018 were retrospectively reviewed. Among 270 patients referred to the HA service unit (HASU), the percentage of final decisions to continue using HAs was calculated.Results: The average pure tone thresholds on initial visit to the clinic were 56.9, 60.6, 69.4, and 82.4 dB HL in patients in their 60s, 70s, 80s, and 90s, respectively. The rates of progression were 0.25, 0.87, 1.19, and 1.37 dB/year in patients in their 50s, 60s, 70s, and 80s, respectively. The percentage of patients in HASU who chose to use HAs did not differ among the 60s (59.3%), 70s (51.2%), and 80s and older (58.2%).Conclusions and significance: The clinical picture of patients with SNHL in their 70s and 80s differs because progression accelerates exponentially through these ages. HAs can be recommended to older adult patients in all the age groups.

[Role of Visiting Nursing Care in Japanese Home Healthcare]

Taiwan's rapidly aging society is expected to make it a super-aged society in 2026. By 2060, people aged 65 or older will account for 40% of the population, a ratio that will approximate that in Japan. In Japan, the elderly population was 27.3% in 2016. By 2025, when the baby-boomers become 75 years old in Japan, issues of long-term care and end-of-life care will be more important and challenging. Since 1976, more Japanese have died in hospital settings than in home settings. Although the percentage of people dying at home increased slightly to 12.7% in 2016, after the recent introduction and promotion of home healthcare, Japan will face a significant challenge to deal with the healthcare 'tsunami' of high natural death rates, which is expected to impose a heavy death burdened on society by 2040, when the death rate is expected to reach 1,670,000/year. Therefore, the Japanese authorities have begun to promote the Community-based Integrated Care System, in which home healthcare and visiting nursing play crucial roles. This article summarizes the historical trend and current situation of visiting nursing in Japan. Japan uses a hybrid payment system for visiting nursing that is financially supported both through private medical insurance policies and Kaigo insurance (Japanese long-term care insurance). The total of 8613 visiting nursing stations that were active in community settings in 2016 cooperated with 14,000 support clinics for home healthcare and cared for 570,000 patients in home settings. We believe that visiting nursing will play an important role in home healthcare in Taiwan in the future.

Japan as the front-runner of super-aged societies: Perspectives from medicine and medical care in Japan

BACKGROUND

The demographic structure of a country changes dramatically with increasing trends toward general population aging and declining birth rates. In Japan, the percentage of the elderly population (aged ≥65 years) reached 25% in 2013; it is expected to exceed 30% in 2025 and reach 39.9% in 2060. The national total population has been decreasing steadily since its peak reached in 2008, and it is expected to fall to the order of 80 million in 2060. Of the total population, those aged ≥75 years accounted for 12.3% as of 2013, and this is expected to reach 26.9% in 2060. As the demographic structure changes, the disease structure changes, and therefore the medical care demand changes. To accommodate the medical care demand changes, it is necessary to secure a system for providing medical care. Japan has thus far attained remarkable achievements in medical care, seeking a better prognosis for survival; however, its medical care demand is anticipated to change both qualitatively and quantitatively. As diseases in the elderly, particularly in the old-old population, are often intractable, conventional medical care must be upgraded to one suitable for an aged society. What is required to this end is a shift from "cure-seeking medical care" focusing on disease treatment on an organ-specific basis to "cure and support-seeking medical care" with treatments reprioritized to maximize the quality of life (QOL) for the patient, or a change from "hospital-centered medical care" to "community-oriented medical care" in correlation with nursing care and welfare.

CURRENT SITUATION AND PROBLEMS

(1)  Necessity for a paradigm shift to "cure-and-support seeking medical care" In addition to the process of aging with functional deterioration of multiple organs, the elderly often suffer from systemically disordering diseases, such as lifestyle-related diseases, as well as geriatric syndrome and daily activity dysfunction; therefore, integrated and comprehensive medical care is required. In addition, with regard to diseases in the elderly, not only their acute stage, but also their chronic and intermediate stages must be emphasized in their treatment. Aiming to achieve a complete cure of disease by exploring the cause and implementing radical treatment, the conventional medical care model is difficult to apply to the medical care of the elderly; medical care suitable for the elderly is required. (2)  Spread of home-based care and the necessity for human resources development Many elderly people want to continue to live in their house and their community where they have been living for a long time, even with disease. There are increasing needs for QOL-emphasizing home-based care for patients in the intermediate stage after completion of acute stage treatment, or for end-of-life care. Hence, there is a demand for a shift to "community-oriented medical care" for providing comprehensive care supported with medical and nursing resources available in the community. As the percentage of the elderly population (aged ≥65 years) and the availability of medical care resources vary considerably among different regions, it is important that specialists in the fields of public health, medical care, nursing care, and welfare work on establishing a collaborative system suitable for the local characteristics of each region by making the best use of their own specialties. (3)  Necessity for establishing a department of gerontology or geriatric medicine at each medical school In line with the increasing number of elderly people, it is necessary to upgrade the systems for educating and nurturing physicians engaged in healthcare and nursing care for the elderly. It is also necessary to develop the organic cooperation with other medical and nursing care professionals, such as registered nurses and care workers. At present, just approximately 30% of medical schools in Japan have a department specializing in medical care for the elderly and relevant medical education; there is an urgent need to improve the situation, as the majority of universities do not provide any such education. (4)  Necessity for establishing a medical center for promoting medical care provider collaboration, multidisciplinary training and a means to increase public awareness In the medical care for the elderly, comprehensive care must be provided from the viewpoints of both healthcare and nursing care; to improve the quality of such care services, multidisciplinary collaboration and team-based medicine are indispensable. Therefore, physicians, nurses, therapists, pharmacists, dieticians, care managers, and other health care professionals who have thorough knowledge about medical care for the elderly are of utmost necessity. In reality, however, the collaboration of these health care professionals is unsatisfactory, and the degree of understanding of team-based medicine by each medical professional is low. Therefore, as in the case of the establishment of cancer centers within individual regions to promote medical care for cancer, there is a demand to nurture professionals engaged in medical care for the elderly, and to establish a core facility for the promotion of multidisciplinary collaboration and team-based medicine for each region. (5)  Do the people understand the paradigm shift? Currently, not only healthcare professionals, but also many citizens seek "cure-seeking medical care" aiming at a restoration of organ function; however, surveys of the elderly often show that they want to restore independent daily activity, rather than to achieve a "cure." In contrast, in the actual medical care setting, contradictory situations prevail in which the public awareness of the shift to "cure-and-support seeking medical care" is unsatisfactory, including the fact that the majority of recipients of tertiary emergency care are elderly patients.

CONTENTS OF THE PROPOSAL

The Science Council of Japan has the task to propose future visions for the Japanese aging society not only from the viewpoint of the health of each individual, but also from a broader perspective, taking into account the relationship between humans and society. Various issues related to general population aging are posing serious problems, which require prompt resolution. Although we made a number of proposals at the 21st Subcommittee for Aging, the situation has not changed satisfactorily. Accordingly, the present proposals on specific solutions were designed. (1)  In a super-aged society, a paradigm shift to "cure-and-support seeking medical care" should be implemented A super-aged society will consist of an unprecedented demographic structure in which the percentage of only those people aged ≥75 years will increase in the entire population. Therefore, there is an urgent need to prepare for increasing populations of persons in need of long-term care and those who are likely to become in need of long-term care. Given the consideration that "patients are not merely sick persons, but rather living persons," a paradigm shift from conventional "cure-seeking medical care" to "cure and support-seeking medical care" must be implemented. (2)  Facilitate a paradigm shift to community-oriented medical care, and promote the activity of female physicians in the medical care for the elderly A paradigm shift should be promptly facilitated by reorganizing hospital functions and establishing a community comprehensive care system for home-based care to promote the participation of the elderly by themselves in care-supporting society. To further promote the collaboration of medical care and welfare, not only persons in charge of actual regional settings, but also university schools of medicine and regional core medical institutions experienced in medical care for the elderly should take the initiative to promote home-based care and facilitate a paradigm shift to community-oriented medical care. In addition, programs should also be developed to re-educate female physicians who became housewives in order to nurture them to become facilitators of geriatric medicine. (3)  Physicians who are required at local medical facilities must be nurtured through the establishment of a department of gerontology or geriatric medicine at each medical school To facilitate efficient medical care services, medical education and research, and human resources development in support of expected paradigm shifts, it is considered that a department of gerontology or geriatric medicine should be established at each medical school. Furthermore, it is necessary to allocate dedicated teachers of medical care for the elderly to all medical schools, as well as to upgrade practice-participatory drills and to collaborate with a broad range of entities, including local medical institutions, and welfare and nursing care facilities. Efforts must be made to nurture locally wanted physicians through specific efforts concerning team-based medicine. (4)  Promote the establishment of centers for geriatrics and gerontology (provisional name) for medical care collaboration, multidisciplinary training, and a means to increase public awareness To promote the uniform accessibility of expertise on efficient medical care that is best suited for a super-aged society, it is necessary to build a post-graduation educational system under the initiatives of the Japan Geriatrics Society and the National Center for Geriatrics and Gerontology across the nation in cooperation with regional medical schools and the Japan Medical Association. Furthermore, at least one hospital serving as a center for geriatrics and gerontology should be established in each regional block (Hokkaido, Tohoku, Koshinetsu, Hokuriku/Tokai, Kinki, Chushikoku and Kyushu/Okinawa) by making the best use of existing hospitals. By establishing these centers, uniform accessibility for the quality of medical care for the elderly in each region is expected. (ABSTRACT TRUNCATED).
