School bus travel is associated with bullying victimization among Canadian male, but not female, middle and high school students

Bullying and coping with bullying among obese\overweight and normal weight children

This study aimed to determine the obese\overweight and normal weight children's status of encountering and coping with bullying and the correlational factors. This case-control study was conducted with 1.680 students in the second level (5th, 6th, 7th, 8th grades) from September 24, 2018 to May 31, 2019 in the Mediterranean Region in Turkey. The data were collected using a personal information form, the Traditional Peer Victimization Scale and the Coping with Bullying Scale. Data were analyzed using the Shapiro-Wilk test, Mann-Whitney U test, Binary Logistic Regression, Backward Wald Elimination, and Simple Linear and Backward Stepwise Multiple Linear Regression analyses. This study indicated that the risk of becoming victims, bullies or bully-victims increases among boys and 8th grade students. It also found that the risk of being victims and bully-victims increases among children whose father is illiterate. There was no significant difference between obese\overweight and normal weight children in terms of being victims, bullies and bully-victims. Grade level, academic performance, father's education level and awareness of reporting bullying were effective in coping with bullying among the children, while weight was not. Further studies are needed to determine different factors that affect children's coping strategies against bullying.

Active school travel is associated with fewer suicide attempts among adolescents from low-and middle-income countries

Background/Objective: This study explored the association between active school travel (AST) and suicide attempts among adolescents in low- and middle-income countries (LMICs). Method: We used the data from the Global School-based Health Survey, including 127,097 adolescents aged 13-17 years from 34 LMICs. A self-reported survey was used to collect data on AST and suicide attempts as well as some variables. Multivariable logistic regression was performed to assess the association between AST and suicide attempts. A meta-analysis with random effects was undertaken to identify the difference in the association between AST and suicide attempts. Results: Across all the adolescents, the prevalence of AST was 37% and the prevalence of suicide attempts was 11.60%. Adolescents who engaged in AST were less likely to have suicide attempts irrespective of gender. The country-wise analysis indicated a large inconsistency in the association between AST and suicide attempt across the countries. Conclusions: AST would appear to be a protective factor for reducing suicide attempts among adolescents. However, the association between AST and suicide attempts varied greatly across the countries. Future studies should confirm the association between AST and suicide attempts.

Associations between the Canadian 24 h movement guidelines and different types of bullying involvement among adolescents

BACKGROUND

The Canadian 24-Hour Movement Guidelines for Children and Youth recommend ≥60 min of physical activity per day, ≤2 h of recreational screen time per day, and 9-11 hours of sleep per night for 11-13 years old and 8-10 hours per night for 14-17 years old.

OBJECTIVE

This study examined the association between combinations of these recommendations and school bullying and cyberbullying victimization and perpetration among adolescents.

PARTICIPANTS AND SETTING

A total of 5615 Canadian students (mean age = 15.2 years) who participated in the 2017 Ontario Student Drug Use and Health Survey (OSDUHS) self-reported their physical activity, screen time, sleep duration, and their involvement in bullying.

METHODS

Logistic regression analyses were adjusted for important covariates.

RESULTS

Meeting the screen time recommendation alone was associated with lower odds of being a victim (OR: 0.64; 95 % CI: 0.46-0.88) or a bully (OR: 0.64; 95 % CI: 0.43-0.96) at school and a victim of cyberbullying (OR: 0.67; 95 % CI: 0.49-0.91). Meeting both the screen time and sleep duration recommendations was associated with lower odds of being a bully (OR: 0.51; 95 % CI: 0.30-0.88). Meeting all 3 recommendations showed stronger associations (i.e. lowest risk) with being a victim of school bullying (OR: 0.32; 95 % CI: 0.19-0.54), a bully-victim (OR: 0.25; 95 % CI: 0.08-0.78) or a victim of cyberbullying (OR: 0.37; 95 % CI: 0.17-0.84).

CONCLUSIONS

Our findings provide evidence that meeting the 24 -h movement guidelines is associated with lower odds of bullying involvement. Encouraging adherence to the 24 -h movement guidelines could be a good behavioural target to prevent involvement in both school bullying and cyberbullying.
