Provision of Medical Big Data for Osaka Metropolitan University Analysis ofthe Relationship between Outings During the Pandemicand Lifestyle Disease Medical Expenses
Japan System Techniques Co., Ltd. (JAST) is supplying medical big data for the purpose of supporting data analysis performed
by a research group led by Senior Lecturer Haruka Kato and Professor Atsushi Takizawa of the Graduate School of Human
Life and Ecology at Osaka Metropolitan University. This research project is conducted as part of an agreement for cooperation
between JAST and the Graduate School of Human Life and Ecology, Osaka Metropolitan University.

Summary of the Research ProjectAt the Graduate School of Human Life and Ecology at Osaka Metropolitan University, a research group led by Haruka Katoand Atsushi Takizawa performed an analysis to determine the relationship between the activities of residents of large cities
using specific categories of transportation and medical expenses for treating lifestyle diseases. Data during the coronavirus
pandemic between April 2020 and September 2021 were used for this research. Analysis revealed that, using January 13, 2020as the pre-pandemic basis value (100%), outings by foot exceeding the 70% level resulted in lower lifestyle disease medical
expenses in all prefectures of Japan. Furthermore, when outings by automobile exceeded the 80% level in all areas of Japanother than metropolitan areas, expenses for treating lifestyle diseases increased. Overall, this research demonstrated theexistence of a relationship between the methods people used for outings and the change in lifestyle disease medical expenses.
This information will serve as a guideline for the types of outings and transportation that should be used during a pandemic tolower expenses for treating lifestyle diseases.
For this research project, JAST supplied JAST medical data sets (note 1) as part of the agreement for mutual cooperation
between JAST and Osaka Metropolitan University.
The results of this research were explained in an article in the November 25, 2023 issue of an International academic journal
called the Journal of Transport & Health.

NEWS RELEASE

The World Health Organization has declared the end of the global healthemergency that was caused by the COVID-19 pandemic. Currently, work
is under way to assess measures that were used to prevent the spread ofinfections during the pandemic. In particular, this work requires
interdisciplinary research using the comprehensive knowledge that is oneof the strengths of Osaka Metropolitan University. I hope that the resultsof this research will be used as basic data for determining ways to combat
future pandemics.

Haruka Kato, Senior Lecturer◼

Background of the Research Project

Restrictions that prevented people from going out during the pandemic had the benefits of holding down the number of
infections and maintaining sufficient capacity for hospital care. However, there were reports of many health problems causedby these restrictions. Lifestyle diseases were the greatest threat to living a long and healthy life even before the pandemic
started. Furthermore, as a significant percentage of total healthcare expenditures in Japan, expenses for treating lifestylediseases have become a serious social problem.
