In the context of the novel Coronavirus outbreak and China’s official policy of free vaccination against COVID-19 for all, medical students’ attitudes and knowledge toward vaccines can influence public acceptance to some extent, however, the large base of non-medical students cannot be ignored. We aimed to investigate the knowledge, attitude, and willingness toward the COVID-19 vaccine among medical and non-medical students. Online surveys were completed by 652 medical students and 590 non-medical students to compare differences in knowledge and attitude of COVID-19 vaccine and vaccination willingness from three universities in the Zhejiang Province. The awareness rate of the vaccine among medical students (65.3%) was higher than that of non-medical students (53.6%). The approval rate of medical students for the safety and efficacy of the COVID-19 vaccine was higher than that of non-medical students. 81.8% of university students were willing to be vaccinated against COVID-19; Multiple stepwise regression analyses showed that lower class grades, rural students’ origin, COVID-19 vaccine attitude and higher cognition level of health self-management influenced the acceptance of COVID-19 vaccination among medical students. However, urban origin, COVID-19 vaccine attitude were the factors hindering non-medical students’ vaccination against COVID-19. The knowledge, attitude and willingness toward the COVID-19 vaccine on medical and non-medical students had different characteristics. Moreover, health self-management was associated with COVID-19 vaccination willingness. Staff involved in the university should pay more attention to the self-managementability of students, send out accurate and transparent information to enhance their cognitive level, further improving the students’ willingness to receive the COVID-19 vaccine.

The prevalence of and risk factors for uncertainty stress among residents during the COVID-19 pandemic remain unclear. An online cross-sectional survey was conducted to explore and identify the risk factors for high perceived uncertainty stress among the general public in China during the COVID-19 outbreak. Information about the respondents' socioeconomic characteristics, knowledge of and attitudes towards COVID-19, perceived uncertainty stress, social capital, anxiety, and depressive symptoms was collected and analysed. Among the 1205 respondents, 45.3% (546) reported a high level of uncertainty stress. Multiple linear regression analysis indicated that anxiety (β=3.871,P<0.001) and depression symptoms (β=2.458, P<0.001), family residence (in towns or rural areas) (β=0.947, P<0.001), lack of support for local epidemic control strategies (β=1.253, P<0.001), worry about the pandemic (β=1.191, P<0.001), and symptoms of weakness among family members (β=1.525, P=0.002) were positively associated with perceived uncertainty stress. Cognitive social capital (β=-0.883, P<0.001) and social networks (β=-0.726, P<0.001) were negatively, but social participation (β=0.714, P<0.001) was positively associated with perceived uncertainty stress. Our findings identify factors associated with a higher level of uncertainty stress and should be helpful in the consideration of effective policies and interventions for uncertainty stress during the initial phases of public health emergencies.

Background: An organ donation coordinator plays an important role in the process of organ donation and transplant. Therefore, investigating and analyzing the current situation in organ donation and examining the correlation between professional identity and psychological resilience of human organ donation coordinator, provides a reference for promoting stable development of organ donation.Methods: A total of 48 coordinators of organ donation in Zhejiang Province were recruited for the study by using the method of convenience sampling. The psychological resilience scale and professional identity questionnaire were used to collect data.Results: The results revealed that the total average score of the professional identity of organ donation coordinators was 34.92 ± 8.57. Compared with the median professional identity score of 34.50, the professional identity of the coordinator in this survey was at a moderate level. The total average score of psychological resilience was 64.44 ± 11.91. There was a significant positive correlation between the professional identity of the coordinator and the total score of psychological resilience (r = 0.641, P &lt; 0.01).Conclusion: The professional identity and psychological resilience of the coordinators in Zhejiang Province were found to be in the middle level and the higher the psychological resilience score, the stronger the professional identity of the coordinators. It is important to improve the level of psychological resilience among organ donation coordinators to enhance their professional identity.

Abstract-In recent years, with the rapid development of national economy, people are improving their living standards day by day and paying growing attention to food safety. Food cannot be separated from packaging, and security problems caused by food packaging are increasingly serious. As child is a special vulnerable group among consumers, food safety problems concerning with them even could not be ignored. For the past few years, infant food security incidents have been frequently exposed, leaving painful tragedies for children, families and the society, and food packaging problems have become an "invisible killer" that infringes the physical and mental health and safety of children. This article conducts a detailed analysis to the current security status of food packaging materials of infant food in China, which are illustrated from three aspects: the inherent safety problems of food packaging materials of infant food, security issues brought by lack of standardization of packaging material production, and safety problems due to incompletion of the detection system and related laws for packaging materials. This text also suggests strategies for the security problems of infant food packaging materials, and makes prospects for its future development. (Abstract)

Grandparenting is known to impact psychological health in older people. However, the extent to which the effect is altered by migration‐related and sociodemographic determinants is less clear. Therefore, we conducted this cross‐sectional study to investigate whether the association between grandparenting and psychological distress differs between rural–urban migrants and local older adults from May to September 2019. A total of 373 rural–urban migrants and 602 local older adults involved in grandparenting in Hangzhou completed measurements assessing sociodemographic characteristics, childcare burden and psychological distress. In total, 22.2% of the grandparents reported psychological distress. Rural–urban migrant grandparents had a lower socioeconomic status (SES), a higher childcare burden (23.6 ± 9.2 vs. 20.7 ± 9.5, p < 0.001) and higher levels of psychological distress (29.8% vs. 17.4%, p < 0.001) than local grandparents. Childcare burden and pressure from adult children were the most significant predictors for psychological distress in both groups (ps < 0.05). Psychological distress was also significantly associated with self‐rated health status (β = −0.276, p = 0.033) and willingness to participate in grandparenting (β = −0.659, p = 0.024) in migrant grandparents but associated with female gender (β = 0.346, p = 0.022), caring for children at night (β = 0.424, p = 0.011), conflict with adult children (β = 0.432, p < 0.001) and annual income (β = −0.237, p < 0.001) in local grandparents. Migrant status showed a statistically significant moderating effect between childcare burden and psychological distress. These results may be of assistance in comprehensively understanding the social determinants of mental health of grandparents involved in grandparenting.
