Background: The effect of long-term exposure to air pollution on the development of chronic obstructive pulmonary disease (COPD) is still controversial, and the role of the interactions of air pollution with genetic risk and lifestyle in COPD risk is unclear. Methods: We included 452762 participants derived from the UK Biobank. Annual concentrations of air pollutions, including particle matter (PM2.5, PM10), nitrogen oxides (NOx), and nitrogen dioxide (NO2), were assessed using land-use regression model.
Cyberbullying is associated with increased risk of suicidal and self-harm behaviors in children and adolescents. However, no review to date has explored factors that exacerbate and mitigate this relationship. This systematic review concerns research on factors that influence the impact of cyberbullying on suicidal and self-harm behaviors. Four bibliographic databases were explored and references in included articles were searched. We identified 727 articles and retained 66 that met inclusion criteria.
