Abstract

It is worth paying attention to the level of worry and fear of students during the normalization of the epidemic. We conducted the cross-sectional study that included 182,991 high school students using an online survey to assess worry and fear levels and its influencing factors in three cities in Henan Province, China, from May 21 to May 27, 2021. Worry and fear levels were measured using a five-item Likert-type scale. Multinomial logistic regression was used to analyze the risk factors. Approximately 65.42% of students reported being high worry about the coronavirus disease 2019 (COVID-19) epidemic, and about 41.44% of students reported being high fear about the COVID-19 epidemic. In addition, compared with female, male had lower odds of suffering from a high worry, and compared with senior high school students, junior high school students were more likely to suffer from a high worry. Students lived in rural had highest odds increased likelihood of high worry. Similar results in fear levels. During the normalization period of the COVID-19 epidemic, many students have high levels of worry and fear. This study has implications for potential influencers of worry and fear levels in follow-up work.

Abstract

Mobile food ordering apps (MFOAs) have become increasingly prevalent in the food service industry. This study investigated the links between intensity of MFOA use, restaurant performance, and customer satisfaction in dine-in restaurants using real transaction data and crowdsourced reviews. Our distinctive datasets stem from a renowned chain of restaurants in China as well as from Da Zhong Dian Ping (referred to as the Chinese equivalent of Yelp), spanning the years 2018 to 2021. Using a high-dimensional fixed effects model, we found that the intensive use of MFOA is positively correlated with an increase in restaurant dine-in revenue through higher table turnovers. However, MFOA is negatively correlated with dine-in restaurant consumer satisfaction, which was associated with lack of adequate, favorable, and high-quality comments. We also conducted several heterogeneity analyses to investigate how selected restaurant characteristics may moderate these effects. Thus, our study provides valuable theoretical insights and practical implications for academia and food service practitioners. [ABSTRACT FROM AUTHOR]

Abstract

Background: Evidence for the relationship between individual and combined volatile organic compounds (VOCs) and cardiovascular disease (CVD) is limited. Besides, the mediating role of biological aging (BA) has not been studied. Therefore, this study aimed to examine the association between VOCs and CVD risk and to explore the mediating effects of BA. Methods: Logistic regression models were used to investigate the relationships of metabolites of volatile organic compounds (mVOCs) and BA with CVD. In addition, weighted quantile sum (WQS) regression, adaptive elastic networks, and Environmental Risk Score (AENET-ERS) were utilized to assess overall associations of mixed VOCs co-exposure with CVD. Mediation analyses were used to identify potential mediating effects of BA. Results: In the single-pollutant model, CYMA was shown to be associated with an increased risk of CVD. Additionally, we identified significantly positive associations between the WQS index and CVD (odds ratio (OR) = 1.292, 95% confidence interval (CI): 1.006, 1.660), and DHBMA had the greatest contribution for CVD (0.246). Furthermore, the AENET-ERS results showed that 8 mVOCs were significantly associated with CVD, and ERS was related to an elevated risk of CVD (OR = 1.538, 95%CI: 1.255, 1.884). Three BA indicators mediated the association of the mVOCs mixture with CVD, with mediating effect proportions of 11.32%, 34.34%, and 7.92%, respectively. Conclusion: The risk of CVD was found to increase with both individual and combined exposure to VOCs. BA mediates the positive effects of VOCs on CVD, suggesting that this pathway may be one of the mechanisms of CVD. Highlights: Individual and mixed exposure to VOCs were associated with elevated CVD risk. DHBMA dominates mixtures of mVOCs for increased CVD risk. BA mediates the effect of VOCs mixture exposure on CVD. [ABSTRACT FROM AUTHOR]
