Multivariable (adjusted) results control for child sex, age, USC, health insurance, well-child checkup, number of siblings (ages 8–17 years), respondent’s relationship to the index child, parent sex, age, race/ethnicity, primary language, acculturation, marital status, educational attainment, family income, and US region of residence.
Predefined NHIS poverty thresholds are based on the weighted average federal poverty thresholds (US Census Bureau) for the previous calendar year, as the reference period for income questions in the NHIS is the previous calendar year.
FPL indicates federal poverty level; HPV, human papillomavirus; US, United States; USC, usual source of care; OR, (unadjusted) odds ratio; AOR, adjusted odds ratio; CI, confidence interval.
