ABSTRACT

BACKGROUND@#The 2019 novel coronavirus disease (COVID-19) has had a massive impact on public health, resulting in sudden dietary and behavioral habit changes. Frontline epidemic prevention workers play a pivotal role against COVID-19. They must face high-risk infection conditions, insufficient anti-epidemic material supplies, mental pressure, and so on. COVID-19 seriously affects their dietary and behavioral habits, and poor habits make them more susceptible to COVID-19. However, their baseline dietary and behavioral habits before COVID-19 and their willingness to change these habits after the outbreak of COVID-19 remain unclear for these workers in China. This study aimed to explore the baseline dietary and behavioral habits of frontline workers and their willingness to change these habits after the outbreak of the epidemic; in addition, susceptible subgroups were identified by stratified analyses as targets of protective measures to keep them from being infected with COVID-19.@*METHODS@#A cross-sectional study was conducted through an online questionnaire using a sample of 22,459 valid individuals living in China, including 9402 frontline epidemic prevention workers.@*RESULTS@#Before COVID-19, 23.9% of the frontline epidemic prevention workers reported a high-salt diet, 46.9% of them reported a high frequency of fried foods intake, and 50.9% of them smoked cigarettes. After the outbreak of COVID-19, 34.6% of them expressed a willingness to reduce salt intake, and 43.7% of them wanted to reduce the frequency of pickled vegetables intake. A total of 37.9% of them expressed a willingness to decrease or quit smoking, and 44.5% of them wanted to increase sleep duration. Significant differences in the baseline dietary and behavioral habits and the willingness to change their habits were observed between frontline epidemic prevention workers and other participants. Among the frontline epidemic prevention workers with poor dietary and behavioral habits before COVID-19, frontline epidemic prevention experience was a promoting factor for adopting worse dietary and behavioral habits, including those in the high-salt intake subgroup (OR, 2.824; 95% CI, 2.341-3.405) and the 11-20 cigarettes/day subgroup (OR, 2.067; 95% CI, 1.359-3.143).@*CONCLUSIONS@#The dietary and behavioral habits of frontline epidemic prevention workers were worse than that those of other participants before COVID-19. They had a greater willingness to adopt healthy dietary and behavioral habits after experiencing the outbreak of COVID-19. However, frontline epidemic prevention workers with poor dietary and behavioral habits before COVID-19 continued in engage in these poor habits. Dietary and behavioral intervention policies should be drafted to protect their health, especially frontline epidemic prevention workers with poor habits at baseline.

ABSTRACT

Objective To investigate the changes of nuclear factor-κB (NF-κB),tumor necrosis factor-α(TNF-α),and cell apoptosis of cerebral ischemia-reperfusion injury and the influence of brain-derived neutrophic factor(BDNF) on these parameters in rats.Methods Eighty-four male Sprague-Dawley (SD) rats were randomly divided into two groups:BDNF (n =42) and control (n =42) groups.The BDNF group was induced using the improved Zea-longa method and were received abdominal injections of BDNF (0.5 μg/μl) immediately after injury.The control group was received abdominal injections with the same dose sodium chloride injection immediately after injury and repeated one time everyday until the rats was killed.Each group was divided into seven subgroups by sacrificed time after injury,including subgroups 1 h,3 h,6 h,12 h,24 h,3 d,and 7 d; each subgroup got 6 rats.Each subgroup were randomly selected three rats after being killed.The expressions of NF-κB and TNF-α of rats contusion peri tissues brain tissue were detected by immunohistochemical methods.Terminal deoxynucleotidyl transferase (TUNEL) method was used to observe the peri cell apoptosis after brain contusion.Results The expressions of NF-κB and TNF-α in BDNF group was significantly decreased relative to the control group (P < 0.05),with a significant positive correlation between two parameters in two groups (P < 0.001).The number of apoptotic cells was significantly decreased in the BDNF group relative to control group (P < 0.05).Conclusions Brain-derived neutrophic factor probably relieves inflammation response,reduces the change of secondary brain injury after traumatic brain injury,and decreases neural cell apoptosis,and finally provides protection of neurocytes.
