The Role of Bedtime Procrastination, Rumination, Loneliness, and Positive Body Image in Predicting Sleep Quality Among University Students: A Sex-Specific Analysis.

Objective: This study aimed to analyze the impact of bedtime procrastination, rumination, loneliness, and positive body image on university students' sleep quality, and to explore potential mediating pathways and sex differences.

Methods: A total of 674 students from a university in southern China were recruited. Assessments of participants' body measurements were conducted, followed by the completion of a general information questionnaire, Pittsburgh Sleep Quality Index, Bedtime Procrastination Scale, Body Appreciation Scale, Body Image-Acceptance and Action Questionnaire, Ruminative Responses Scale, and University of Loneliness Scale.

Exploring exercise, emotional eating, and body dissatisfaction in depression risk: Using structural equation modeling.

In order to fill the relevant research gap on the influence of body dissatisfaction on depression in Chinese college students, we used structural equation modeling to explore the relationships between physical activity, body dissatisfaction, eating behavior, and depression. Participants were 1,714 undergraduate students in Southern China. Exercise served as a significant mediator between body mass index and depression, as well as between body dissatisfaction and emotional eating, accounting for 30% and 19.

Numerical Simulation of Blood Flow in Nutcracker Syndrome: Acquisition of Hemodynamic Parameters and Clinical Application.

Adopting noninvasive techniques to provide more precise parameters related to the clinical diagnosis and treatment of nutcracker syndrome is currently the focus of research on nutcracker syndrome. However, due to individual differences in patients and limitations in monitoring techniques, there is an urgent need for a new method to obtain more accurate parameters. This work is based on imaging data from two patients with nutcracker syndrome and numerically simulates the blood flow process in the left renal vein, revealing different clinical symptoms caused by changes in flow velocity, pressure, and wall shear stress.

Exploring the relations between body dissatisfaction, rumination, physical activity, and restrained eating: a latent moderated structural equation approach.

Background: Previous studies have shown that body dissatisfaction is closely related to restrained eating, however, the specific mechanisms and conditions of body dissatisfaction need to be further explored. Therefore, this study aims to explore the mediating and moderating variables influencing the relations between body dissatisfaction and restrained eating, providing recommendations for the prevention of restrained eating among university students.

Methods: Participants comprised 1213 university students who completed the Negative Physical Self Scale, Ruminative Responses Scale, Restrained Eating Scale, and Physical Activity Scale.

Mediating role of exercise in the relationship between body dissatisfaction and overeating using structural equation modeling.

Background: With the rapid development of society, teenagers have more access to individuals with perfect bodies and are becoming more concerned about their body image. Currently, few studies assess body image and eating disorders comprehensively in China. Given the seriousness of these issues, there is an urgent need to understand the current state of body image and eating behaviors among Chinese people and formulate preventive strategies.

Spatiotemporal distribution characteristics and influencing factors of the rate of cardiovascular hospitalization in Ganzhou city of China.

Aims: The objective of this study was to analyze hospitalization rates for cardiovascular diseases (CVD) in Ganzhou City, Jiangxi Province of China from 2015 to 2020 and to uncover the spatiotemporal distribution characteristics and influencing factors, and thus to provide reference for the prevention and control of CVD and public health resources planning.

Methods: The hospitalization data for CVDs from 2016 to 2020 was obtained from the First Affiliated Hospital of Gannan Medical University, and ArcGIS 10.8, SaTScan 9.
