Cycling has proven to be an important strategy in decreasing the risk of non-communicable diseases. This study aimed to discover barriers and enabling factors influencing satisfaction and safety perceptions towards the use of bicycle roads in the Seoul metropolitan area, South Korea. A cross-sectional survey of 190 youth and adult individuals was conducted. Sex, age, purpose of bicycle use, perceived safety, availability of facilities, road gradient, road width, and traffic on the bicycle road were associated with cycling regularity. Multivariate regression analysis showed that the sufficiency of bicycle parking space, moderate slope, and enough bicycle signs were significant enabling factors for satisfaction with the use of bicycle roads. Narrow bicycle roads were found to be a barrier to satisfaction with the use of bicycle roads. Moderate slope, enough bicycle signs, and enough maintenance facilities around bike roads were found to be enabling factors in the perceived safety of the use of bicycle roads, whereas traffic on the side of the bicycle road was found to be a barrier to perceived safety. Based on these findings, we conclude that healthy cities should promote cycling behavior encouraging enabling factors and initiating attempts to improve the factors that act as barriers through urban planning.

This study aimed to evaluate the effectiveness of a school-based mental health education program in preventing adolescent suicide attempts in an impoverished urban area in Peru, as part of an Official Development Assistance project by the Korea International Cooperation Agency. The PRECEDE-PROCEED model informed the effectiveness study. In this intervention, the participants were first to fifth grade students in public secondary schools. The pre-post intervention survey was conducted with a stratified random sampling method. A sample of 768 and 738 students in experimental and control groups was analyzed comparatively, using chi-squared tests and logistic regression. This study found that the program had a positive effect on adolescent mental health-related risk behaviors and suicide attempts in the experimental group compared to the control group. Thus, the intervention may have helped prevent the increase in mental health-related risk behaviors and suicide attempts. Further, parental affection, when included in the intervention, had a significant effect on suicide attempts. As such, the involvement of parental affection in the intervention might be effective in preventing suicide attempts. To enhance the effectiveness of interventions aiming to prevent adolescent suicide, the participation and attention of parents, as well as adolescents, must be encouraged. Further, to maintain the effectiveness of the intervention and expand coverage to other schools in the neighborhood, a strategy for project sustainability is needed, particularly with regards to capacity-building in schools and communities.

Witnessing inter-parental violence and bullying victimization is common for many children and adolescents. This study examines the role of witnessing inter-parental violence and bullying victimization in involvement in physical fighting among Peruvian adolescents. A cross-sectional study was conducted among 1,368 randomly selected adolescents in 2015. We conducted logistic regression analyses to obtain crude and adjusted odds ratios with 95% confidence intervals for involvement in fighting among male and female adolescents. Among all adolescents, 35.8% had been involved in fighting in the last 12 months, 32.9% had been victim of verbal bullying and 37.9% had been the victim of physical bullying. Additionally, 39.2% and 27.8% of adolescents witnessed violence against their mother and father, respectively, at least once in their lives. Multivariate logistic regression analyses found that late adolescence, participation in economic activities, being the victim of verbal bullying, stress, and witnessing violence against the father among male adolescents, and self-rated academic performance and being the victim of physical or verbal bullying among female adolescents were associated with higher odds of being involved in fighting. Verbal bullying victimization and witnessing violence against the father in males and bullying victimization in females were associated with greater odds of adolescents being involved in fighting. Creating a non-violent environment at both home and school would be an effective strategy for reducing fighting among the adolescent population.
