ABSTRACT
Objective To evaluate the knowledge, behavior and psychological status regarding COVID-19 epidemic in elementary and secondary school teachers, and to provide a reference for disease prevention and control at schools as well as for preparation of school returning. Methods A survey in 2 338 teachers was conducted using self-designed questionnaires about COVID-19. Results The overall awareness rate of COVID-19 knowledge was 88.79%, knowledge score was 10.65±1.09, and the school health teachers had higher score than other school staff (F＝23.87, P=0.000 1).Respondents with IP address in Hubei had higher score than those in Jiangsu, Zhejiang and Shanghai(F＝10.69, P=0.014).The top three knowledge resources were news apps (Toutiao, Tencent) (87.25%), WeChat (78.06%) and telecast (74.94%).The overall healthy behavior score was 43.59±3.12, and school doctors again had higher score than other school staff (F=11.48, P=0.02).Respondents with IP address in Hubei had higher score than those in Jiangsu, Zhejiang and Shanghai (F=17.08, P=0.000 7). During the epidemic, 100% respondents wore masks when taking public transportation, the highest rate of wearing masks, while 90.93% wore masks at family and friends gathering, the lowest rate of wearing masks.The top three types of masks being used were disposable medical masks (89.14%), surgical masks (43.63%) and N95 medical protective masks (34.09%).The highest rate of hand washing behavior was 99.83% for washing hands after going to toilet, while the lowest was 75.92% for washing hands after touching hair, ears and nose.The highest rate of other healthy behaviors was 94.14% for reducing family and friend gatherings, while the lowest was 71.60% for covering mouth and nose when sneezing or coughing. The correlation between health behavior and knowledge was statistically significant (r=0.081, P < 0.001).Correlation analysis showed that the degree of concern was related to the degree of teaching influence (r=0.768, P=0.0002), and the degree of anxiety was related to the degree of teaching influence (r=0.175, P < 0.001), while there was no correlation between the degree of concern and the degree of anxiety. Conclusion Elementary and secondary school teachers generally have high score in the COVID-19 knowledge test, and behaved well in wearing masks.Hand hygiene education should be further improved.There are concerns about the impact of COVID-19 epidemic on teaching.
ABSTRACT
Objective To investigate the impact of early health status on the risk of developing child overweight and obesity so as to provide evidences for preventive measures against child overweight and obesity.Methods Three schools were randomly selected from primary schools in Shanghai, and another three schools were randomly selected from 9-year schools in Shanghai.Retrospective surveys were conducted for 1 511 pupils selected from all the Grade One and Grade Two students of the above selected schools, the univariate and multivariate logistic regression analyses were used to analyze the early risk factors for child overweight and obesity.Results The results of univariate logistic regression analyses showed that for the children with relatively high birth weights, asthma, allergic constitution, histories of chronic diseases, relatively good appetite, relatively high ages that had been notified of their overweight and obesity, the detection rate of overweight and obesity was higher (P<0.05).The results of multivariate logistic regression analyses showed that birth weights(OR=2.699, 95%CI=1.097~6.644), allergic constitution(OR=1.498, 95%CI=1.044~2.149), histories of chronic diseases(OR=2.486, 95%CI=1.327~4.659) and appetite(OR=22.011, 95%CI=8.861~54.673) were the risk factors influencing child overweight and obesity (P<0.05).Conclusion Attention still needs to be paid to the body mass control of the children with relatively high birth weights, allergic constitution and histories of chronic diseases.Scientific and reasonable feeding at early stages as well as cultivating good eating and drinking habits may help prevent and control child overweight and obesity.
