Press Release: Older Adults Engaged in Social Participation Are More Likely to Maintain Independence Until the End of Life (Co-researcher: Takayuki Ueno)

A research group led by Takayuki Ueno, a researcher at the Tokyo Metropolitan Institute for Gerontology, and Professor Naoki Kondo of our lab had previously identified five patterns of physical function decline during the last three years of life: “maintained independence until death,” “rapid decline,” “gradual decline,” “moderate maintenance,” and “severe maintenance.” In this study, the group revealed that older adults who participated in social activities at least once a month in 2010 were more likely to follow the “maintained independence” trajectory compared to those who did not engage in social activities.
The findings of this study offer valuable insights into extending healthy life expectancy and improving the quality of life (QOL) for older adults. These results underscore the necessity of promoting social participation in future older adult care policies.

Paper publication: Discovering daily life needs of older public assistance recipient subgroups (Assistant Professor Ueno)

Health disparities have become a major social issue in Japan. To reduce health disparities, it is necessary to shift from individual-level to societal-level interventions. Since 2021, health management support programs for public assistance recipients have been mandated in welfare offices. Assistant Professor Keiko Ueno and her colleagues focused on older public assistance recipients, particularly those in need of health and daily life support, and identified the daily life needs of older public assistance recipient subgroups.

In 2021, we conducted interviews with four caseworkers from the welfare offices in two districts. The results of our previous quantitative study, which identified five subgroups of older public assistance recipients by sex, were presented to caseworkers. They were asked about their daily life needs in each subgroup. The interview results revealed the following five daily life needs among the subgroups of older public assistance recipients: (1) housing, (2) financial,(3) welfare service utilization, (4) medical, and (5) no specific daily life needs. These findings indicate that appropriate support interventions are necessary for each subgroup of older public assistance recipients. Future studies are warranted to conduct interviews with professionals from other fields (such as public health nurses and social workers) to further understand the daily life needs of the subgroups of older public assistance recipients.

Press Release: Living Arrangement Status and Treatment Effectiveness of Cardiovascular Prevention – (Medical Student Kanta Kiyohara)

Medical student Kanta Kiyohara, Associate Professor Kosuke Inoue, Professor Taku Iwami, and Professor Naoki Kondo published a study using data from a large-scale randomized controlled trial to reveal that the effectiveness of intensive glycemic and blood pressure control among patients with diabetes varies by living arrangement status (living alone or not).

This research, published in the Journal of the American Heart Association (JAHA) on June 27, 2024, highlights the need to consider living arrangements, particularly living alone, as a critical social determinant of cardiovascular health that can modify the effectiveness of cardiovascular prevention among individuals with diabetes.

Press release: 3.8 times the risk of depression when moving to temporary housing; however, those who changed their participation in group activities upon moving had a 40% reduction in the risk (Visiting Researcher Matsuoka)

A research group led by Yoko Matsuoka (Chiba University, Center for Preventive Medical Sciences) and Professor Naoki Kondo analyzed the effect of post-disaster relocation on mental health and the factors explaining this effect among the affected older adults of the 2016 Kumamoto earthquake.

Post-disaster relocation is a risk factor for worsening mental health, but the mechanism has not been elucidated. Therefore, we analyzed the effect of relocation on mental health by housing type and what factors explain this effect. We included 828 older adults aged 65 years or older who participated in the 2013 survey before the earthquake and seven months later in the 2016 survey in Mifune Town, Kumamoto Prefecture, which was affected by the April 2016 Kumamoto earthquake. Focusing on participation in group activities, the risk of depression due to relocation to temporary housing was 3.8 times higher for those who had no change before and after the earthquake, but this risk was reduced by 40% for those who had a change in group participation. After the 2016 Kumamoto earthquake, temporary housing facilities were relocated based on lessons learned from past earthquakes and tsunami disasters, including group relocation policies, the establishment of meeting places in proximity, and visitation activities by support centers. There, residents were able to change their involvement in group activities and optimize their connections, which may have led to a reduction in relocation stress.

The paper was published in BMC Public Health in the online edition on October 11, 2023.

Paper Publication: Development and validation of Healthy Ageing indicator proposed by the United Nations (PhD student, Marisa Nishio)

Marisa Nishio, PhD student, announces the publication of a research paper concerning the validity of the concept of Healthy Ageing proposed by the United Nations.

The United Nations has designated the period from 2021 to 2030 as the “Decade of Healthy Ageing,” encouraging countries worldwide to monitor the progress of Healthy Ageing using Functional Ability as an indicator (Functional Ability refers to the combination of an individual’s physical and mental abilities and the supportive environment enabling them to utilize these abilities). However, the measurement for Functional Ability and its conceptual validity have not been extensively studied, making the implementation of monitoring efforts challenging.

This research utilized data from approximately 35,000 older individuals residing in Japan to develop a measurement for Functional Ability and assess its validities. 

Her study confirmed the empirical validity of Functional Ability. To promote the global dissemination and monitoring of Healthy Ageing, further research validating the concept of Functional Ability using data from other countries is essential.

This study was published in “Age and Ageing,” a journal by Oxford University Press.

Paper publication: Paramedics require more than 30 minutes of activity at the scene in older patients, female patients, fire accidents, natural disasters, motor vehicle accidents, assaults, self-injuries, number of hospital inquiries ≥ 4, and the COVID-19 pandemic among ambulance users with minor diseases or injuries (Assistant Professor Ueno)

Prolonged activity time of paramedics at the scene is a major global problem in the emergency medical system (EMS). Assistant Professor Keiko Ueno conducted collaborative research with Hiroshima University, utilizing data from the ambulance transportation and request call records databases of the Higashihiroshima Fire Department over a period of seven years. They revealed that paramedics required more than 30 minutes of activity at the scene in older patients, female patients, fire accidents, natural disasters, motor vehicle accidents, assaults, self-injuries, number of hospital inquiries ≥ 4, and the COVID-19 pandemic among ambulance users with minor diseases or injuries. We need to reconsider how to intervene with potentially modifiable factors, such as EMS personnel performance, the impact of the presence of allied services, hospital patient acceptance systems, and cooperation between general emergency and psychiatric hospitals to improve community EMS.

Press release: Depressive symptoms, suicide ideation and attempts are about twice as common among those who perceive community gender norms as restrictive (Collaborator Kanamori)

A research group led by Mariko Kanamori (Kyoto University Institute for the Future of Human and Society) and Professor Naoki Kondo reported the impact of perceived community gender norms, such as “You are a man/woman, you shouldn’t/shouldn’t do XXX”, on the mental health of older people.

Men who perceived the gender norms of the community they lived in as restrictive were 1.9 times more likely to have depressive symptoms, 2.0 times more likely to have suicidal thoughts and 2.2 times more likely to have attempted suicide. Similarly, women were 1.8 times more likely to have depressive symptoms, 2.1 times more likely to have suicidal thoughts and 2.6 times more likely to have attempted suicide.

The results of this study suggest that those who perceive the atmosphere in their community as being rigid about gender roles and think that it does not allow for diversity are less likely to seek help in times of need, which in turn has a negative impact on their mental health.

The paper was published in International Psychogeriatrics, a leading journal in the field of gerontology and psychology, in the First View online edition on November 6, 2023.
