  • Notes: All regressions included the following control variables: maternal characteristics at delivery (age; education; marital status; residence county urbanicity; chronic hypertension; chronic diabetes) and parity. The American Academy of Pediatrics provides the recommended number of annual well-child visits, which decreases with age: 6 visits at age 0 to <1 year; 3 visits at age 1 to <2 years; 2 visits at age 2 to <3 years; and 1 visit annually from age 3 to 21 years. Thus, the threshold for meeting the recommended WCV receipt decreases with age, and having any WCV receipt at age 3 to <4 years is equivalent to having the recommended receipt of WCVs.

  • Abbreviations: CI, confidence interval; OR, odds ratio; PNCC, Prenatal Care Coordination; WCV, well-child visit.
