SUMMARY OBJECTIVE: This study aimed to investigate the suboptimal health status or subhealth status and their relationship with mental health and smartphone addiction among Chinese medical students. METHODS: A cross-sectional survey was conducted at Wannan Medical College of China in Wuhu. RESULTS: A total of 2,741 students were surveyed in October 2020. Of 2,741 Chinese medical students who completed the survey, 904 (33%) participants reported to have had subhealth status. Anxiety status (p<0.001), depression status (p<0.001), and smartphone addiction status (p<0.001) have strong association with subhealth status. CONCLUSION: This survey shows that the detection rate of subhealth status in Chinese medical students was 33%. Anxiety, depression, and smartphone addiction students had a higher detection rate of subhealth status. The anxiety, depression, and smartphone addiction of Chinese medical students are associated with subhealth status.

SUMMARY OBJECTIVE: This study aimed to assess the attitudes of Chinese residents toward COVID-19 vaccines and explore the potential drivers for Chinese residents' vaccine hesitancy. METHODS: A cross-sectional survey was conducted from February 16 to March 16, 2021, by administering an online questionnaire to the Chinese residents. RESULTS: Of 5240 residents who completed the survey, 464 (8.9%) participants reported to have had one shot, and 348 (6.6%) reported to have had 2 shots. At the time the questionnaire was administered, 2298 (43.9%) participants reported they wanted to get vaccinated, while 2255 (43.0%) declared that they still did not know, and 687 (13.1%) respondents declared vaccine refusal. Overall, 2255 (43%) participants were categorized as vaccine hesitancy. Female participants (p=0.000), <20 years old (p=0.000), have low risk of COVID-19 (p=0.000) infection and strong associations of vaccine hesitancy. eHealth literacy was a protective factor. CONCLUSIONS: The results of this study show high rates of vaccine hesitancy in China. This could pose a serious threat to the preventive measures that aimed at controlling COVID-19 spread in the country. The government and different media platforms should encourage the dissemination of correct information about vaccines, the communities and medical staff to improve residents' knowledge about vaccines, and strive to improve residents' electronic health literacy.

RESUMO OBJETIVO O objetivo do nosso estudo foi confirmar a relação entre o exercício de baixa intensidade e o estado de saúde física e mental entre estudantes universitários na China. MÉTODOS Estudo transversal com base na escola foi realizado neste estudo. O estado de saúde física e mental foi medido recorrendo-se a questionários gerais de saúde (GHQ12); exercícios de baixa intensidade foram coletados por questionários de autorrelato. RESULTADOS Os resultados revelaram que a pontuação do GHQ12 foi inversamente associada com maior frequência de exercícios de baixa intensidade (r=–0,38, p=0,001). CONCLUSÕES Nosso estudo sugeriu que o exercício de baixa intensidade pode ser um meio adequado para melhorar o estado físico e mental dos estudantes universitários. O departamento relacionado à escola deve tomar alguma medida para forçar os alunos a participar da atividade física.

SUMMARY OBJECTIVE The purpose of our study was to confirm the relationship between low-intensity exercise and physical and mental health status among college students in China. METHODS This was a school-based cross-sectional study. The physical and mental health status was measured using a 12-item general health questionnaire(GHQ12) and low-intensity exercise was recorded by a self-reporting questionnaire. RESULTS The results revealed that the score of the GHQ12 was inversely associated with a higher frequency of low-intensity exercise (r=-0.38,p=0.001). CONCLUSIONS Our study suggests that low-intensity exercise may be a proper mean for improving the physical and mental health status of college students. School departments should take measures to push students to take part in physical activity.
