Professor Saeda Ochi of the Jikei University School of Medicine and others conducted joint research with the Research Institute of Economy, Trade and Industry to investigate how the weight and exercise habits of Japanese people changed due to the corona crisis, and found that they were polarized. .
According to the Jikei University School of Medicine, the research group conducted an online questionnaire on about 1 men and women registered as monitors with NTT Communications, who were selected to match the distribution of all Japanese people by age, gender, and place of residence. We asked about the number of days of exercise per week.
As a result, during the period from October 3 to October 5, which corresponds to the third to fifth waves of the new coronavirus, the number of people whose exercise habits decreased significantly increased, even though the average number of days of exercise habits increased. Was.Although the average value of BMI (Body Mass Index), an international index that indicates the degree of obesity, increased only slightly, the standard deviation, which indicates the variation in values, expanded.The research group analyzed that the polarization of exercise habits and body weight occurred.
An analysis was conducted assuming that there are groups that are particularly susceptible to the effects of the corona virus, and it was found that elderly women and men with a history of COVID-XNUMX infection were at a higher risk of losing exercise habits and gaining weight, while middle-aged men were at a higher risk of weight gain. Became.On the other hand, people who had exercise habits before the corona disaster tended to increase the number of days of exercise even during the epidemic.
