“…Therefore, accessibility to food in South Korea was not as difficult as it was in other countries during the COVID-19 pandemic. In fact, a nationwide cross-sectional study of Korean adolescents in 2020 reported that the consumption of fast food and carbonated drinks decreased during the pandemic ( 29 ). In addition, the proportion of individuals eating breakfast and home-cooked food increased, thus improving unhealthy dietary habits.…”

BackgroundThis study aimed to examine changes in obesity rates and obesity-related factors during the COVID-19 pandemic compared to a previous period.MethodsAn ecological time-series study was designed using the Korean National Health and Nutritional Examination Survey (KNHANES) database from 2014 to 2020. The expected values of obesity rate, physical activity rate, and nutrient intake for 2020 were estimated. The differences between the predicted and actual values for 2020 were also examined. In addition, a multiple logistic regression model was used to examine the changes in obesity and physical activity rates in 2020 compared to 2019.ResultsThe actual obesity rates in 2020 were higher, and the walking and aerobic physical activity rates were lower than the predicted values for the same year. However, the actual resistance training rates in 2020 were higher and the total energy intake was lower than the predicted values for 2020. In the multiple logistic regression model, the odds ratios for obesity, aerobic physical activity, and walking among men in 2020 were 1.29 (95% CI: 1.08 to 1.55), 0.86 (0.74 to 1.01), and 0.84 (0.73 to 0.97), respectively, compared to those in 2019. However, there were no significant differences between the values for women in 2020 and 2019.ConclusionsThis study suggests that the male obesity rate in Korea has significantly increased during the COVID-19 epidemic, mainly due to a decrease in physical activity.

“…On a global level, the COVID-19 home confinement had a negative effect on all physical activity intensity levels from vigorous to low, while daily sitting time increased from five to eight hours per day [ 19 ]. Kim et al reported that the frequency of aerobic exercise was lower, while the frequency of anaerobic exercise was higher during the COVID-19 pandemic in Korea [ 34 ]. This observation is presumably transferable to our own results on the increased use of online tutorials that potentially integrate aspects of anaerobic high-intensity functional or high-intensity interval training to time effectiveness and resource-saving improved fitness [ 35 ].…”

The COVID-19 pandemic has dramatically impacted human lifestyles across the world. Lockdowns and home confinement decreased prior opportunities for everyday physical activity. To retrospectively assess how the Austrian population coped with these aspects of the crisis, we conducted a cross-sectional online survey from March to September 2021 using a structured questionnaire in German. In total, 1214 participants (56.9% females, mean age 37.0 years) living across Austria shared self-reported information on sociodemographic characteristics, indoor and outdoor physical activity, reasons for being outdoors, and life satisfaction before and after the emergence of the virus. As a result, overall indoor physical activity significantly decreased in a before–during COVID-19 crisis comparison, although exercising at home with online instructions increased by about 63%. Exercising outdoors increased overall, specifically in periurban forests and rural areas, both by about 9%. Life satisfaction decreased significantly by 19.7% (p < 0.001). Outdoor public places and natural environments gained importance due to restrictions affecting access to sport facilities. Further research is needed to evaluate benefits and therapeutic values of outdoor nature for physical and mental health in times of a global pandemic to maintain resilient societies, as it might impact future active living and life satisfaction.

“…Screen time duration and consumption of discretionary foods (e.g., cakes and candy) increased [ 9 , 10 , 11 , 12 ], physical activity decreased [ 10 , 13 , 14 ], and bedtimes and wake-up times shifted to later [ 15 , 16 ]. Sugar-sweetened beverage (SSB) intake [ 9 , 10 , 17 ] and sleep duration [ 10 , 15 , 18 ] also changed, although the direction of change was not consistent across studies. Among United States (U.S.) children, one study mirrored these findings.…”

This longitudinal study compared children’s health behaviors before the COVID-19 pandemic versus during the pandemic. This analysis examined the association between individual-level characteristics and health behavior change. Four prospective cohort studies in the Environmental influences on Child Health Outcomes (ECHO) Program contributed data. Children aged 4–12 years and their caregivers were recruited in California, Colorado, North Dakota, and New Hampshire. Dietary intake, physical activity, screen time, and sleep duration were assessed with questionnaires pre-pandemic and during the pandemic. The final sample included 347 children: 47% female and 62% non-Hispanic White. Compared with pre-pandemic, weekday screen time duration was higher during the pandemic (3.0 vs. 4.5 h, p < 0.001). Unadjusted increases in screen time duration differed by race and ethnicity: 1.3 h/day for non-Hispanic White children, 2.3 h/day for Hispanic children, and 5.3 h/day for non-Hispanic Black children. Overall, no changes occurred in sugar-sweetened beverage (SSB) intake (p = 0.26), discretionary food intake (p = 0.93), and physical activity (p = 0.15). Sleep duration increased by 30 min among children who did not meet sleep recommendations pre-pandemic. Child sex and maternal education level were not associated with health behavior change. The pandemic may have exacerbated disparities in some health behaviors. Families may need support to re-establish healthy routines.
