2.3. Independent variables

Data on home neighborhood built environment, bedroom electronic presence, parental rules, and demographics were collected with the BEAP Study questionnaire. Built environment, bedroom electronic presence, and parental rules were assessed with 14 questions (Table 1). All questions elicited yes/no responses, with the exception of the following question: “What type of building is your home/your child's home?” For this question, participants were required to mark “detached single family home”; “townhouse”; “condominium or apartment building” or “other”. Both child and parent demographics were assessed with questions on age, gender, race, ethnicity and origin of birth.
