Acute injury or illness related to the inhalation of vaping aerosols among children and adolescents across Canada: A cross-sectional survey of Canadian paediatricians.

Background
Vaping prevalence rates have increased among Canadian youth. Evidence suggests that vaping poses signiﬁcant health risks to children and adolescents.


Objectives
The objectives of the study were to investigate epidemiological characteristics of acute injury/illness cases due to the inhalation of vaping aerosols among children and adolescents across Canada and to explore factors contributing to severe cases.


Methods
Data from the 2019 Canadian Paediatric Surveillance Program cross-sectional survey on vaping-related injury/illness were used. Analyses focused on injury/illness cases (n=71) among children and adolescents aged 0 to 17 years who presented to participating paediatricians for a harm related to the inhalation of vaping aerosols. We conducted descriptive analyses and performed logistic regression to explore associations between severe presentations requiring hospitalization or intensive care unit (ICU) admission and selected case characteristics.


Results
Of the 71 reported injury/illness cases related to inhalation of vaping aerosols, 56% of patients were male, and 68% were aged 15 to 17 years. Nicotine vaping was reported in 42% of cases, and cannabis vaping in 24%. Fifty-four per cent presented with respiratory distress, 18% with symptoms of nicotine toxicity, and 41% required hospitalization and/or admission to the ICU. Cases presenting with respiratory distress were more likely to be hospitalized/admitted to the ICU (odds ratio [OR]=5.37, 95% confidence interval [CI]:1.76 to 16.39).


Conclusions
The inhalation of vaping aerosols among children and adolescents may contribute to acute injury/illness. Clear associations between study variables and severe cases could not be established due to a small sample size. Additional research is needed to determine predictors and preventable risk factors of severe vaping-related injuries.
