Cleft Lip and Palate in Newborns Diagnosed With Neonatal Abstinence Syndrome.
Academic Article
Overview
abstract
OBJECTIVE: Cleft lip and/or cleft palate (CLP) is the most common major congenital malformation of the head and neck. Previous studies suggested an association between fetal opioid exposure and CLP. This study seeks to evaluate the associations between CLP and neonatal abstinence syndrome (NAS) in the United States. STUDY DESIGN: Population-based inpatient registry analysis. SETTING: Academic medical center. SUBJECTS AND METHODS: Kids' Inpatient Database (2016) was used to identify weighted in-hospital births with diagnoses of CLP or NAS. Demographic information was obtained. RESULTS: Among 3.8 million weighted in-hospital births, prevalence rates of CLP in the NAS and non-NAS populations were 3.13 and 1.35 per 1000, respectively. The odds ratios for patients with NAS developing CLP, isolated cleft palate, isolated cleft lip, and cleft lip and palate when compared with the reference population were 2.33 (95% CI, 1.87-2.91; P < .001), 4.97 (95% CI, 3.84-6.43; P < .001), 1.01 (P = .98), and 0.80 (P = .46). Independent predictors of CLP within the NAS population included median household income for patients' zip code, race, hospital region, payment method, and maternal use of tobacco or other drugs of addiction. The binary logistic regression model accounting for possible confounding variables produced an odds ratio of 1.74 (95% CI, 1.36-2.23; P < .001) for the association between NAS and CLP. CONCLUSION: Our study found an association between NAS and CLP, specifically isolated cleft palate, suggesting that prenatal exposure to opioids may be an environmental risk factor in the development of CLP.
