PLoS ONE 16(3):Įditor: John William Apolzan, Pennington Biomedical Research Center, UNITED STATES (2021) Possible favorable lifestyle changes owing to the coronavirus disease 2019 (COVID-19) pandemic among middle-aged Japanese women: An ancillary survey of the TRF-Japan study using the original “Taberhythm” smartphone app. Despite the many negative effects of the COVID-19 pandemic, subjective feelings of happiness among middle-aged Japanese women tended to increase, which indicates that some favorable lifestyle changes that could be adopted during quarantine in the ongoing COVID-19 pandemic.Ĭitation: Azuma K, Nojiri T, Kawashima M, Hanai A, Ayaki M, Tsubota K, et al. Additionally, there was a positive association of happiness with steps per day in Period B (ρ = 0.38, p = 0.02). Moreover, daily eating duration declined in this population. We found a surprising trend during Period B toward increased happiness among women aged 30–50 years, the group most affected by stay-at-home policies that led to working from home and school closure. 3528 ± 3397 steps/day, p<0.001) however, there were large variations in physical activity among participants. 3814 ± 3529 steps/day, p<0.001), especially during the final 9 weeks in both periods (4907 ± 3908 vs. Compared with Period A, there was a sharp decline in physical activity during Period B (4642 ± 3513 vs. A total of 464 smartphone users (346 women, 35 ± 12 years old, body mass index 23.4 ± 4.5) participated in Period A (January 7 to April 28, 2019) and 622 smartphone users (533 women, 32 ± 11 years old, BMI 23.3 ± 4.0) participated in Period B (January 6 to April 26, 2020).
We aimed to compare lifestyle data before and during the first phase of the COVID-19 pandemic to objectively assess lifestyle changes during quarantine. Prior to the COVID-19 pandemic, we developed a smartphone application called “Taberhythm” to investigate eating patterns, physical activity, and subjective feelings of happiness. Many people have become physically inactive and developed irregular eating patterns, which leads to unhealthier lifestyles and aggravation of lifestyle-related diseases these in turn increase the severity of COVID-19. Coronavirus disease 2019 (COVID-19) has had a global effect on people’s lifestyles.
