Background: Although a mobile nursing application has began to adopt in nursing, few studies have focused on nurses’ behavioral intention of it. The objective of this study is to gain insight into the behavioral intention of nurses, i.e. chinese nurses of the future, to use a mobile nursing application. This study adopted an extension of the Unified Theory of Acceptance and Use of Technology to examine Chinese nurses’ acceptance of a mobile nursing application. Methods: A total of 1207 nurses participated in the cross-sectional survey. The majority of nurses were female (96.2%). The mean age of the participants was 34.18 (SD 7.39). The hypothesized relationships were tested using AMOS structural equation model. Results: All constructs exhibited an acceptable level of reliability and validity with Cα and CR > 0.7 and AVE > 0.5. An extension of the Unified Theory of Acceptance and Use of Technology Model had good explanatory power for nurses’ behavioral intention of a mobile nursing application. Although effort expectancy and perceived risks had a surprisingly insignificant effect on nurses’ behavioral intention to use a mobile nursing application, performance expectancy, social influence, facilitating conditions, self-efficacy, and perceived incentives demonstrated significant influence with β = .259, p < .001, β = .296, p < .001, β = .063, p = .037, β = .344, p < .001, β = .091, p = .001, respectively. Conclusion: With 70.2% of the variance in behavioral intention to use a mobile nursing app explained by this model, it could be helpful for potential adopters, and further investigation should test the actual usage behavior for a mobile nursing app and investigate the related factors.

Background: The utilization of short videos by individuals often leads to the emergence of information exchange behavior. Previous studies have shown that certain students with psychological disorders exhibit addictive tendencies towards short video-related software. Therefore, it is essential to address the psychology and behavior of college students with psychological disorders while engaging with short videos. This study aims to explore the mechanism of short video information interaction behavior among college students with psychological disorders. Methods: We conducted semi-structured interviews with 30 college students afflicted by psychological disorders in a prefecture-level city in Henan Province, China from September to December 2022. Based on the Grounded theory, we encoded 30 text materials across three levels to explore the mechanism of short video information interaction behavior among college students with psychological disorders, and subsequently build a model framework. Results: The findings of this study suggest that college students with psychological disorders exhibit negative cognition tendencies that can lead to strongly negative emotions, excacerbated by a lack of social support. These adverse factors collectively drive the consumption of short video content in this demographic, providing a virtual environment where they can fulfill their unmet social needs. Therefore, the mechanism governing short video messages interaction among college students with psychological disorders encompasses negative cognitive tendencies, negative emotions, lack of social support, post-video-watching behaviors, and the gratification of social needs within the confines of a virtual environment. Conclusions: This study comprehensively analyzes the motivation and complexity of college students with psychological disorders in short video interaction. Although short videos provide this group with some ways of self-expression and emotional support, they still have a negative impact on their physical and mental health. The short video interaction of college students with psychological disorders is affected by many factors, including their negative cognitive tendencies, negative emotions, lack of social support, post-video-watching behaviors, and the gratification of social needs within the confines of a virtual environment. These findings deepened our understanding to the mechanism of short video information interaction behavior among college students with psychological disorders, also provided us with guidance on facilitating the proper use of short video and maintaining the mental health. In future researches, researchers can discuss more about intervention measures to help this demographic cope with the challenges from short video interaction.

With the popularity of the internet, short videos have become an indispensable tool to obtain health information. However, avoiding health disinformation owing to the openness of the Internet is difficult for users. Disinformation may endanger the health and lives of users. With a focus on the process of identifying short videos' health disinformation and the factors affecting the accuracy of identification, this study aimed to investigate the identification methods, coping strategies, and the impact of short videos’ health disinformation on undergraduate nursing students. The findings will provide guidance to users on obtaining high-quality and healthy information, in addition to reducing health risks. Semi-structured in-depth interviews were conducted with 22 undergraduate nursing students in October 2022, and data were collected for collation and content analyses. The techniques used to identify short videos that include health disinformation as well as how undergraduate nursing students perceived these videos' features are among the study's findings. The failure factors in identification, coping paths, and adverse impacts of short videos on health disinformation were analyzed. The platform, the material itself, and the students' individual characteristics all have an impact on their identifying behavior. Medical students continue to face many obstacles in identifying and responding to health disinformation through short videos. Preventing and stopping health disinformation not only requires individual efforts to improve health literacy and maintain rational thinking, it also requires the joint efforts of short video producers, relevant departments, and platforms.

The association between abdominal obesity and pulmonary function trajectories among patients with COPD remain to be unclear. This study aimed to explore the association between abdominal obesity and pulmonary function trajectories among patients with COPD. Data were collected from the China Health and Retirement Longitudinal Study, which was a nationally representative investigation. The pulmonary function indicator was peak expiratory flow (PEF). Abdominal obesity was assessed using waist circumference, which was categorized into two groups: < 90/85 cm and ≥ 90/85 cm, in men/women. Latent class growth analysis was used to identify distinct pulmonary function trajectories. The logistic regression was used to assess the association between abdominal obesity and pulmonary function trajectories. Finally, a total of 775 patients with COPD aged 45 years and older were included, and 301 participants (38.84%) were abdominal obesity. The mean PEF value showed a decreasing trend, with respective average values of 205.84 L/min (SD = 104.16), 199.99 L/min (SD = 99.52), and 196.06 L/min (SD = 86.74) in 2011, 2013 and 2015. Two PEF trajectories were identified: “above average-high descending” trajectory (n = 187, 24.13%) and “low-maintenance” trajectory (n = 588, 75.74%). Unadjusted and adjusted analysis showed that baseline higher waist circumference was associated with “low-maintenance” trajectory. A negative association between abdominal obesity and pulmonary function trajectories was observed among patients with COPD. This suggests that increased abdominal fat may accelerate the decline of pulmonary function over time. These findings provide evidence for designing targeted programs to improve pulmonary function, particularly for patients with COPD of abdominal obesity.

Background: Few quantitative studies have explored the associations between nut consumption and better health outcomes among a national cohort of community-dwelling older Chinese people. Given the need for more evidence to support the health benefits of nuts among Chinese people, we investigated whether nut consumption was associated with subsequent 10-year mortality.Methods: We analyzed data from the Chinese Longitudinal Healthy Longevity Survey. The data on nut consumption at baseline were collected using a questionnaire through face-to-face interviews. The vital status and date of death were ascertained by a close family member or village doctor of the deceased participant during the follow-up survey. Cox analyses were performed to explore the association between nut consumption and mortality. Subgroup analyses by age group (<80 or ≥80 years), sex (male/female), activities of daily living (impaired or normal), and physical exercise (yes or no) were performed to assess whether the association between nut consumption and mortality differed across different populations.Results: The median survival time was 1,302 days for the 11,915 participants with complete information of survival time and nut consumption. The association between nut consumption and mortality was significant after the adjusting for significant factors in the univariate Cox analyses. The hazard ratios were lower in male participants, those who were <80 years old, and those who did not engage in physical exercise at baseline. The association between nut consumption and mortality was not significant among participants with normal activities of daily living.Conclusion: The association between nut consumption and mortality was not significant among participants who had normal activities of daily living but was significant among participants who had impaired activities of daily living. Including nuts in the diets cloud help to extend the lifespan in older Chinese people, especially those with impaired activities of daily living.

Background:The rapid expansion of social media has given rise to a myriad of challenges among college students facing psychological distress. An abundance of fragmented and repetitive information, often referred to as information overload, inundates users on social media platforms. This inundation presents significant hurdles for college students experiencing psychological distress when acquiring and processing information. This study investigates the associative mechanisms between information overload in the context of social media and information avoidance behaviors among college students experiencing psychological distress.Methods:From May to November 2023, semi-structured interviews were conducted with 30 college students experiencing psychological distress in a prefecture-level city in Henan Province, China, to collect textual data. Grounded theory was employed to conduct three-level coding of the 30 sets of textual data. Special emphasis was placed on analyzing the process of perceiving social media information overload. Subsequently, this analysis served as the foundation for constructing a factor model influencing information avoidance behaviors among college students experiencing psychological distress.Results:The study findings indicate that, within the context of social media, college students experiencing psychological distress are prone to prolonged exposure to information overload, leading to the development of negative emotions such as anxiety and fatigue, subsequently resulting in dissatisfaction with social media. In order to alleviate these negative emotions, they employ information avoidance strategies. These strategies evolve from initially skipping or skimming information to eventually directly avoiding or even discontinuing the use of specific social media platforms. This process is not only closely linked to negative emotions but is also influenced by negative cognitive tendencies. Coupled with the role of virtual social satisfaction and social scarcity, it easily triggers social comparisons and the fear of missing out, resulting in a cyclic impact.Conclusions:Within the context of social media, information overload and information avoidance behaviors among college students experiencing psychological distress are subject to a cyclic influence stemming from negative emotions, negative cognitive tendencies, virtual social satisfaction and social scarcity, social comparisons, and the fear of missing out. This study explores the mechanisms underlying the impact of information overload and information avoidance behaviors among college students experiencing psychological distress within the context of social media. It offers valuable insights for the prevention and intervention of psychological crises among college students.
