Model 1†1.56 (1.12 to 2.17)1.90 (1.48 to 2.44)1.87 (1.33 to 2.63)

  • *Model 1: OR and 95% CI is based on mixed-effect logistic regression with person-specific random intercept and adjustment (fixed effect) for wave, age, sex, race and parental education.

  • †Model 2: OR and 95% CI is based on mixed-effect logistic regression similar to model 1 with additional adjustment (fixed effect) for primary smoking or vaping of nicotine or cannabis, and secondhand smoking or cannabis smoking or vaping exposure.

  • ‡The OR and 95% CI for wheeze, bronchitic symptoms and shortness of breath is based on mixed-effect logistic regression models.
