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.

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.

Press Release: Women who could use mHealth consultation services during the perinatal period had a two-third lower risk of postpartum depression (Doctoral Student Arakawa)

Mr. Arakawa, a Ph.D. candidate at the University of Tokyo (Special research student at Kyoto University), Prof. Kondo, and colleagues published the article investigating the effectiveness of mHealth consultation services for preventing postpartum depression.

This study included pregnant women living in Yokohama city. It revealed that women who were provided mHealth consultation services, in which women could consult about their concerns related to pregnancy and childcare with obstetrician-gynecologists, pediatricians, and midwives through their mobile phone during the pregnancy and postpartum periods, had a two-third lower risk of postpartum depression compared with women who were not provided them. This result indicates that removing physical and psychological access barriers to healthcare is critical to improving mental health for perinatal women.

This study was published in BMC Medicine, the flagship journal of the BMC series.
