  1. Abbrevations: pseudo-R 2 pseudo R squared, is a number that indicates how well the data fit a logistic regression model
  2. NL denotes participants with a Dutch ethnicity, SNA denotes participants with a Surinamese, Netherlands Antillean or Aruban ethnicity, MENA denotes participants with a Middle Eastern or North African ethnicity (including Turkish participants), Other denotes participants from all other ethnicities
  3. Interpretation of the OR of continuous determinants: If a determinant increases with one unit, we expect to see the odds to be HPV vaccinated (i.e. received 1 or 2 doses) to increase with the specified ratio for that determinant. For example, if among the Dutch intention increases with one unit, we expect to see the odds to be HPV vaccinated to increase 5.67 times
  4. Interpretation of the OR of categorical determinants: the odds to be vaccinated are x-times higher in the non-reference categories compared to the reference category. For example, in the Dutch group if the daughter received all childhood vaccinations the odds to also become HPV vaccinated (i.e. received 1 or 2 doses) is 10.43 times higher compared to when the daughter did not receive all childhood vaccinations
  5. aThe multivariable analyses was executed by adding variables in three step: (step 1) intention, (step 2) proximal determinants, and (step 3) distal determinants. During each step backward selection was applied to reduce the number of determinants.
  6. ¥ Overall vaccination status for vaccinations taking place between 0 and 9 years old (HPV vaccination is offered at the age of 12-13 years)
