Growth in Children with a Cleft Lip and/or Palate in 8 US Hospitals: A Retrospective Cohort Study

OBJECTIVES: To evaluate growth patterns in US children with cleft overall and by cleft lip (CL), CL and palate (CLP), and cleft palate (CP) across US children's hospitals from 0 to 18 mo of age. DESIGN: We conducted a retrospective cohort study leveraging medical records from 2009 to 2022 in children with a cleft seen at 8 US children's hospitals. PARTICIPANTS: Individuals with a cleft seen at a PEDSnet consortium hospital. EXPOSURE: We examined growth over time, by cleft type, and across hospitals. MAIN OUTCOMES: We used electronic health data to generate weight-for-age z scores (WAZ) and length-for-age z scores (LAZ), as well as underweight (WAZ <-2) and stunting (LAZ <-2). We tracked longitudinal growth using generalized linear mixed models to estimate mean WAZ and LAZ from 0 to 18 mo of age. We compared the prevalence of underweight and stunting against World Health Organization growth standards. RESULTS: Our sample included 10,223 children: 19.1% with CL, 31.7% with CLP, and 49.2% with CP. WAZ and LAZ trajectories showed a fast rate of decline in the first 4 mo of life (P < 0.001). Between 6 and 12 mo and between 12 and 18 mo, WAZ showed a significant nonlinear increase in growth (P < 0.01) while LAZ remained unchanged (P > 0.05). All children had a higher prevalence of underweight and stunting relative to World Health Organization growth standards. Underweight and stunting were highest among those with CP, followed by CLP and then CL, and varied across hospitals. CONCLUSIONS: Growth trajectories were slower in the first 4 mo of life, followed by rapid catch-up in weight to 12 mo of age. Children with cleft had a high prevalence of underweight and stunting at all ages. Variability across hospitals suggests that care patterns may affect growth. Close growth monitoring in the first 4 mo in children with cleft may be warranted.Knowledge Transfer Statement:US children with a cleft of the lip and/or palate have substantial growth deficits that vary by cleft type, comorbidities, and across hospitals, particularly in the first 4 mo of life.
