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.

Objectives
To evaluate the associations of habitual fish oil supplementation with cardiovascular disease (CVD) and mortality in a large prospective cohort.
Design
Population based, prospective cohort study.
Setting
UK Biobank.
Participants
A total of 427 678 men and women aged between 40 and 69 who had no CVD or cancer at baseline were enrolled between 2006 and 2010 and followed up to the end of 2018.
Main exposure
All participants answered questions on the habitual use of supplements, including fish oil.
Main outcome measures
All cause mortality, CVD mortality, and CVD events.
Results
At baseline, 133 438 (31.2%) of the 427 678 participants reported habitual use of fish oil supplements. The multivariable adjusted hazard ratios for habitual users of fish oil versus non-users were 0.87 (95% confidence interval 0.83 to 0.90) for all cause mortality, 0.84 (0.78 to 0.91) for CVD mortality, and 0.93 (0.90 to 0.96) for incident CVD events. For CVD events, the association seemed to be stronger among those with prevalent hypertension (P for interaction=0.005).
Conclusions
Habitual use of fish oil seems to be associated with a lower risk of all cause and CVD mortality and to provide a marginal benefit against CVD events among the general population.
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.
AbstractContextThe patterns of associations between glycated Hb (HbA1c) and mortality are still unclear.ObjectiveTo explore the extent to which ranges of HbA1c levels are associated with the risk of mortality among participants with and without diabetes.Design, Setting, and PatientsThis was a nationwide, community-based prospective cohort study. Included were 15,869 participants (median age 64 years) of the Health and Retirement Study, with available HbA1c data and without a history of cancer. Cox proportional hazards regression models were used to estimate hazard ratios with 95% CIs for mortality.ResultsA total of 2133 participants died during a median follow-up of 5.8 years. In participants with diabetes, those with an HbA1c level of 6.5% were at the lowest risk of all-cause mortality. When HbA1c level was <5.6% or >7.4%, the increased all-cause mortality risk became statistically significant as compared with an HbA1c level of 6.5%. As for participants without diabetes, those with an HbA1c level of 5.4% were at the lowest risk of all-cause mortality. When the HbA1c level was <5.0%, the increased all-cause mortality risk became statistically significant as compared with an HbA1c level of 5.4%. However, we did not observe a statistically significant elevated risk of all-cause mortality above an HbA1c level of 5.4%.ConclusionsA U-shaped and reverse J-shaped association for all-cause mortality was found among participants with and without diabetes. The corresponding optimal ranges for overall survival are predicted to be 5.6% and 7.4% and 5.0% and 6.5%, respectively.
