Prevalence and behavioural associations of unintentional injuries among Chinese college students: a 50-University population-based study

Effects of functional correction training on movement patterns and physical fitness in male college students

The objective of this study is to investigate the effects of functional corrective training and static stretching on the quality of movement patterns and physical fitness in college students. The study was conducted with 30 male college students from a university in Guangzhou, China. The participants were randomly assigned to either the functional corrective training group (FCT, n = 15, age = 20.93 ± 0.85, BMI = 22.07 ± 2.33) or the static stretching group (SS, n = 13, age = 20.85 ± 0.86, BMI = 21.98 ± 1.80). Two participants from the SS group dropped out due to personal reasons, leaving 13 subjects in that group. Both groups underwent a 6-week training intervention, with sessions held twice a week. The FCT group participated in flexibility training, and/or static motor control training, and/or dynamic motor control training for 10-15 min. The SS group performed static stretching exercises targeting five specific muscles, with 30 s per side and two sets. The Functional Movement Screen (FMS), body composition, sit-and-reach, standing long jump, and pull-ups were assessed before and after the intervention. Differences in FMS outcomes were analyzed using two samples of the Mann-Whitney U test. Physical fitness outcomes were analyzed using a repeated measures analysis of variance (ANOVA) with a 2 (group) × 2 (time) design. After 6 weeks of intervention, the FCT group showed statistically significant improvements in the hurdle step (Z = -2.449, p = 0.014), inline lunge (Z = -2.000, p = 0.046), rotary stability (Z = -2.309, p = 0.021), and composite scores (Z = -3.316, p = 0.001). Comparisons between groups indicated that BMI (FCT, ES = 0.04; SS, ES = -0.11), 30-m sprint (FCT, ES = 0.12; SS, ES = 0.28), body fat percentage (BF%) (FCT, ES = -0.25; SS, ES = -0.07), and sit-and-reach (FCT, ES = 0.17; SS, ES = 0.06) were not statistically significant in both the pre- and post-tests. The effect sizes of all physical fitness indicators were greater in the FCT group than in the SS group. The FCT, consisting of two sessions per week for 6 weeks, has been proven to be effective in improving the quality of movement patterns by improved stability and advanced movements. However, the improvements in physical fitness did not reach statistical significance. FMS and FCT are generally affordable and accessible for college students. College students have the opportunity to employ the FMS tool to assess potential injury risks and address them, thereby reducing the risk of injuries.

Late bedtime, uncertainty stress among Chinese college students: impact on academic performance and self-rated health

This study aims to examine the relationship between uncertainty stress and late bedtime behaviour, and to explore their associations with self-rated health and self-reported academic performance. The participants were 11,954 students from 50 universities in China from a cross-sectional survey. College students' bedtime, sleep duration, health status, and academic performance were assessed with a self-reported questionnaire. Uncertainty stress and general life stress were also measured by standard stress questionnaires. The logistic regression models and the path analysis were applied to explore the network relationships among these variables. Late bedtime prevalence among college students was 17.2% (95% C.I. 16.5%-17.9%). Gender, grade, monthly expenditure, and sleep duration were found to be related to the prevalence of late bedtime. Uncertainty stress was more influential on late bedtime and academic performance than general life stress. Students with higher uncertainty stress were 1.41 times more likely to experience late bedtime than those with lower uncertainty stress. Late bedtime was associated with involvement in adverse outcomes including worse self-rated health status and poor academic performance. Many college students were at risk for late bedtime, and those at risk may perceive high uncertainty stress and be at risk for academic failure and health problems. These findings underscore the significance of evaluating and monitoring bedtime in college students and the importance of intervention strategies that target bedtimes and uncertainty stress in an effort to reduce associated self-rated health outcomes and improve academic performance.

Cross-sectional study of gender differences in physical activity-related injuries amongst Chinese college students majoring in rehabilitation

The main objective of the paper was to explore the potential risk factors for physical activity-related injuries (PARI) amongst college students majoring in rehabilitation and to analyse gender differences. A random whole group sampling method was used to recruit freshmen to seniors aged 15-25 years from over 90 universities in China that offer rehabilitation. The total number of people included was 6,032, of which 1,989 were male and 4,043 were female. The underlying risk factors for PARI of different genders were assessed using a structured self-management questionnaire including sociodemographic characteristics, physical activity levels, risk-taking and protective behaviors, and PARI. Totally 6,032 questionnaires were obtained for final analysis, with 792 total number of injured persons (415 males, 377 females), the sum of the cumulative frequency of injuries to injured persons is 1,607 (881 males, 726 females) and a PARI risk of 0.27 (males: 0.44, females: 0.18; p < 0.001; sum of the cumulative frequency of injuries/total number of people surveyed/year). For male and female students, participation in sports teams, having a high level of PA as well as with antisocial behavior were risk factors for developing PARI. Regarding female students, regional differences was associated with elevated odds to suffer from PARI. The prevalence rates of PARI vary between male and female students. The research subjects were university students in rehabilitation. Compared to general college students, rehabilitation students have a certain knowledge base related to injuries, which defines the specificity and research value of this subjects. This study provides guidance for reducing PARI in students in rehabilitation and may provide a basis for developing future injury prevention mechanisms for university students in general.

Regional Internet Access and Mental Stress Among University Students: A Representative Nationwide Study of China

Background

The Internet changed the lives of average citizens in the early part of the twenty-first century, and it has now become an essential part of daily life. Many studies reported that accessibility of Internet use is associated with mental health. However, previous studies examining this association were confined to local and community subpopulations and limited at the individual level, which increases the potential bias from the selection effect at a different level. Regional variables would be a stable estimate of people's socioeconomic and cultural environments and how these variables affect mental health needed to be studied. The objective of this study was to evaluate the association between regional Internet access, and mental stress among university students.

Methods

Participants were 11,954 students, who were identified through a multistage survey sampling process conducted in 50 Chinese universities. Regional Internet access was retrieved from a national database, and mental stress was measured using the Perceived Stress Scale (Chinese Version) (CPSS). Both unadjusted and adjusted methods were considered in the analyses.

Results

More than one-third 36.9% (95% CI: 24.4–49.5%) of university students in this study suffered from severe mental stress (SMR). The multilevel logistic regression model found that university students studied in low-level universities had 2.52 (95% C.I. 1.17 to 6.37) times the prevalence of SMR than those in high-level universities. Compared with small cities, students in a large city had a lower prevalence of SMR (OR 0.25; 95%C.I. 0.06 to 0.77). Most importantly, regional Internet access was negatively associated with students' SMR (OR 0.25; 95%C.I. 0.08 to 0.76).

Conclusions

This study indicated that regional Internet access and other environmental factors including city size and type of universities contribute to students' mental health. The findings underscore that efforts to control excessive mental stress among students in China should pay greater attention to environmental determinants of stress and particularly to improve internet access.

Patterns of six behaviors and psychosomatic symptoms in adolescents: A six-province study in China

BACKGROUND

Psychosomatic symptoms are often related with behaviors. However, the association between different behaviors and their latent patterns and psychosomatic health status is unclear. Current study aimed to identify the patterns of six behaviors and explore the association between different patterns and psychosomatic symptoms in a school-based sample of Chinese adolescents.

METHODS

From November 2015 to January 2016, the study enrolled 22,628 students from six cities in China (15.36 ± 1.79 years). Six behaviors [unintentional injury (UI), non-suicidal self-injury (NSSI), suicidal behaviors (SB), drinking, smoking, screen time (ST)] and psychosomatic symptoms (psychological and physical symptoms) were measured by self-report validated questionnaires.

RESULTS

Six behaviors were all related to psychosomatic symptoms, among which SB was the strongest. Four patterns of behaviors were be identified as follows: low-risk pattern (64.0%), substance use pattern (4.5%), injury pattern (28.8%) and high-risk pattern (2.7%). Logistic regression analysis of psychological symptoms indicated that compared with low-risk pattern, high-risk pattern had the highest risk, followed by injury pattern, substance use pattern showed the lowest risk. Compared with low-risk pattern, the results of physical symptoms suggested the degree of risk was high-risk pattern, injury pattern and substance use pattern, respectively.

LIMITATIONS

Cross-sectional data were used in the study that could not evaluate causal relationships between six behaviors and psychosomatic symptoms.

CONCLUSIONS

Six behaviors and their latent patterns are related to psychosomatic symptoms among Chinese adolescents differently, so different intervention and prevention protocol need to be taken for different patterns of adolescents.

Behavioral and psychosocial correlates of road traffic injuries: evidence from a nationwide study on Chinese undergraduates

Objective: The purpose of this study was to investigate the prevalence and behavioral and psychosocial correlates of road traffic injuries (RTIs) among Chinese university students.Methods: A cross-sectional survey was conducted among fifty universities in China, using a multi-stage sampling methodology. The participants were asked to report their RTIs in the past year. The chi-square test and binary logistic regression analysis were utilized to identify factors associated with RTIs, including specific types of RTIs.Results: Among the 11,770 participants, a total of 1,482 university students reported at least one RTI yielding an overall weighted injury prevalence of 12.96% over the past year. Estimated weighted prevalence by type was 6.10%, 5.94%, 5.12%, and 5.35% for automobile (car, truck, or bus), bicycle, motorcycle, and pedestrian injuries, respectively. Logistic regression analysis found that students who studied at low-level universities, smoked cigarettes, drank alcohol, slept less than 7 hours, went to bed after 12:00 am, or students with psychological distress were more likely to experience overall and four types of RTIs. Students who studied in the eastern universities had a higher likelihood of automobile injury, motorcycle injury and pedestrian injury than those who studied in western universities.Conclusions: Several critical factors associated with RTIs were identified. These findings have implications for the design and implementation of RTI prevention and interventions programs targeted at university students.
