Prematurity, birth weight, and access to a medical home among school-aged children in the US: A cross-sectional survey

Introduction Prematurity and low birth weight (LBW) are associated with higher health care needs and higher health care utilization in the first few years of life. The aim of this cross-sectional study was to determine how prematurity and LBW were correlated with access to a medical home later in childhood, at ages 6–17 years. Methods Data were analyzed from the 2016–2018 National Survey of Children's Health. Non-institutionalized US children 6–17 years of age who had been born preterm were classified as very low birth weight (VLBW, <1500 g), LBW (1500–2500 g), and normal weight (NBW, >2500 g). Term-born NBW children were included as a reference group. Medical home access was determined according to caregiver report. Results The analysis included 64,597 infants (preterm VLBW n  =  737; preterm LBW n  =  2869; preterm NBW n  =  3942; and term NBW n  =  57,049). Based on this sample, 44% of children ages 6–17 years were estimated to receive care meeting the criteria of a medical home. On multivariable analysis, none of the preterm groups had higher likelihood of receiving care in a medical home compared to children born at term and NBW (odds ratios ranging from 0.75 to 0.95). Conclusions School-aged children born preterm and LBW were equally or less likely to receive care meeting the criteria of a medical home than children born at term and NBW. Although prematurity and LBW are associated with increased health care use early in the life course, this does not appear sufficient to help children establish and maintain access to a medical home.
