PURPOSE: To examine the impact of the COVID-19 pandemic lockdown on body mass index (BMI) and physical fitness (PF) among university students in China. METHODS: A total of 5,164 participants (male: 3,604, 69.8%) aged 18.4 ± 0.6 years from three Chinese universities were included in this study. These students were required to undergo BMI and PF tests by their universities annually. Two cohorts of students (the 1st cohort from Oct. 2018 to Oct. 2019, n = 2614; the 2nd cohort from Oct. 2019 to Oct. 2020, n = 2550) were compared, and 1-year changes in BMI and PFs of the 1st cohort (with no pandemic lockdown exposure: NoPL) and the 2nd cohort (with COVID-19 pandemic lockdown exposure: CoPL) were examined in this study. The changes in BMI and PFs were calculated by subtracting the data at baseline from the data at follow-up. Increase in BMI (the upper 25% of the distribution of the BMI change) and decrease in PFs (the lower 25% of the distribution of PFs changes) were the outcome variables. Odds ratios and 95% confidence intervals (95% CIs) for changes in BMI and PFs including vital capacity, 50-meter sprint, sit and reach, standing long jump, pull-ups (only for males) / timed sit-ups (only for females), and 1,000-meter run (only for males) / 800-meter run (only for females) were calculated using logistic regression models after adjustment for age and all other pre-measurement items. RESULTS: Comparing with the NoPL, the odds ratios (95% CIs) for increase in BMI, and decrease in PFs including vital capacity, 50-meter sprint, sit and reach, standing long jump, pull-ups, and 1,000-meter run were 1.68 (1.44-1.97), 1.03 (0.87-1.22), 3.99 (3.34-4.77), 0.74 (0.63-0.87), 1.13 (0.97-1.32), 2.94 (2.48-3.46), and 1.52 (1.30-1.77), respectively for males in the CoPL. Corresponding results in females for increase in BMI and decrease in PFs were 0.30 (0.23-0.39), 1.06 (0.82-1.36), 2.51 (1.97-3.21), 0.38 (0.29-0.49), 0.99 (0.78-1.26), 1.43 (1.13-1.81), and 2.06 (1.63-2.60). CONCLUSIONS: This study showed that there was a significant impact of the COVID-19 pandemic lockdown on BMI, explosive power, flexibility, muscular strength, aerobic fitness in both males and females. These findings may contribute to the development of targeted intervention strategies for weight loss and PF promotion during the lockdown caused by the public health emergency. 

Impact Of The Covid-19 Pandemic Lockdown On Body Mass Index And Physical Fitness Among Chinese University Students

Sports have aspects of "playing," "watching," and "supporting," and most of the studies reported to date on people's health and well-being have identified the health value of "playing" sports. However, limited data are available on the value of sports fans. PURPOSE: This study evaluates the value of sports fans in terms of subjective happiness by assessing the differences between people who are fans of a specific sport, sports team, or athlete and those who are not fans of the same sport. METHODS: This study was conducted using an internet survey targeting people residing in Japan. Participants were 3,077 people consisting of 1,557 women and 1,520 men. Sports fans and subjective happiness, and demographic characteristics of the study participants such as sex, age, occupation, area of residence, marital status, household income, educational background, and the number of persons living together were collected via a self-administered questionnaire. In addition, a questionnaire was used to determine on a 4-point scale whether participants were fans of a sport, sports team, or athlete. Subjective happiness was assessed using the Japanese version of the Subjective Happiness Scale and converted to a binary value using the median. A logistic regression model was used to assess the relationship between sports fans and subjective happiness. Multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated after adjusting for confounding factors. RESULTS: Using the "No, I am not a fan of any sports" group as reference, the age-sex-adjusted ORs and 95% CIs were 1.29 (1.08 − 1.55) for the "I am a fan of sports, but not enthusiastically" group, 1.34 (1.05 − 1.70) for the "I am a somewhat enthusiastic sports fan" group, and 1.86 (1.44 − 2.41) for the "I am an enthusiastic sports fan" group, respectively (p for trend <0.001). After adjustment for additional confounding factors, multivariable-adjusted ORs and 95% CIs were 1.21 (1.00 − 1.46), 1.24 (0.97 − 1.60), and 1.73 (1.32 − 2.27), respectively (p for trend <0.001). CONCLUSIONS: This cross-sectional study showed that men and women living in Japan who reported a high level of sports enthusiasm have higher levels of subjective happiness.
