Coronavirus disease 2019 (COVID-19) has recently emerged as a global threat. Understanding workers’ knowledge, attitudes, and practices (KAP) regarding this new infectious disease is crucial to preventing and controlling it. This study aimed to assess KAP regarding COVID-19 during the outbreak among workers in China. The present study was part of a cross-sectional online survey study conducted based on a large labor-intensive factory, which has 180,000 workers from various Chinese provinces, from 2 February 2020 to 7 February 2020. KAP related to COVID-19 were measured by 32 items, each item was measured with an agree/disagree/unclear format, and only correct responses were given 1 point. KAP regarding COVID-19 were measured with 20 items, 6 items and 6 items, respectively. A total of 123,768 valid responses (68.8%) were included in the analysis. Generally, the levels of knowledge (mean: 16.3 out of 20 points), attitudes (mean: 4.5 out of 6 points), and practices (mean: 5.8 out of 6 points) related to COVID-19 were high. Only 36,373 respondents (29.4%) disagreed that gargling with salt water is effective in protecting against COVID-19. Moreover, older respondents had decreased levels of knowledge and practices related to COVID-19 (both P values for the trend <0.001), while better-educated respondents had increased levels of knowledge and practices related to COVID-19 (both P values for the trend <0.001). These results suggest that Chinese workers are highly aware of COVID-19, but health authorities still need to provide correct information on COVID-19 prevention and strengthen health interventions, particularly for older and less-educated workers.

Objectives To evaluate the associations of regular glucosamine use with all-cause and cause-specific mortality in a large prospective cohort. Methods This population-based prospective cohort study included 495 077 women and men (mean (sd) age, 56.6 (8.1) years) from the UK Biobank study. participants were recruited from 2006 to 2010 and were followed up through 2018. We evaluated all-cause mortality and mortality due to cardiovascular disease (cVd), cancer, respiratory and digestive disease. HRs and 95% cis for all-cause and cause-specific mortality were calculated using cox proportional hazards models with adjustment for potential confounding variables. results at baseline, 19.1% of the participants reported regular use of glucosamine supplements. during a median follow-up of 8.9 years (iQR 8.3-9.7 years), 19 882 all-cause deaths were recorded, including 3802 cVd deaths, 8090 cancer deaths, 3380 respiratory disease deaths and 1061 digestive disease deaths. in multivariable adjusted analyses, the HRs associated with glucosamine use were 0.85 (95% ci 0.82 to 0.89) for all-cause mortality, 0.82 (95% ci 0.74 to 0.90) for cVd mortality, 0.94 (95% ci 0.88 to 0.99) for cancer mortality, 0.73 (95% ci 0.66 to 0.81) for respiratory mortality and 0.74 (95% ci 0.62 to 0.90) for digestive mortality. The inverse associations of glucosamine use with all-cause mortality seemed to be somewhat stronger among current than non-current smokers (p for interaction=0.00080). Conclusions Regular glucosamine supplementation was associated with lower mortality due to all causes, cancer, cVd, respiratory and digestive diseases.on July 9, 2020 by guest.

Highlights The prevalence of anxiety and depression symptoms was 3.4% and 22.8% among workers during the COVID-19 epidemic in China. Epidemic-related factors especially having confirmed cases in the community and having confirmed friends were associated with the higher risk of anxiety and depression symptoms. Major traditional risk factors, such as general or poor health status and always drinking alcohol, were found still to be the dominant factors associating with the increased risk of anxiety and depression symptoms. Approximately 67.3% and 26.8% of workers reported demand for psychological education and interventions, respectively.
