Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.

Abstract

Background: Individuals with orofacial cleft (OFC) may be at higher risk of developing psychiatric disorders(PD). We determined the risk of psychiatric diagnoses in children with OFC in Canada.

Methods: This population-based retrospective cohort study used health administrative data from the province of Ontario, Canada. Children with OFC who were born from April 1, 1994 to March 31, 2017 in Ontario were each matched to five non-OFC children based on sex, date of birth and mother’s age. We determined rate of events and time-to-event for first diagnosis of PD in children aged ≥3 years(y), and for intellectual developmental delay (IDD) from birth. Risk factors for PD and IDD were assessed using 1-way ANOVA for means, Kruskal-Wallis for medians, χ 2 test for categorical variables.

Outcomes: There were 3,051 children with OFC (matched to 15,255 controls), of whom 2,515 OFC patients had complete follow-up to the third birthday (matched to 12,575 controls). The mean age to first PD diagnosis was 8.6±4.2y for OFC patients; the cleft palate group had a higher risk (HR 1.33, 95% CI 1.18-1.49). The OFC patients had a higher risk of IDD diagnosis (HR 8.08, 95% CI 7.28-8.97, p<001), especially those with other congenital malformations (HR 4.57, 95% CI 3.95-5.28 p<0.001). Geography (place of living) was a significant risk factor for PD and IDD.

Interpretation: Children born with OFC in Ontario had a higher risk of psychiatric diagnosis and IDD compared to controls. Further research is required to better understand the cause of geographical variation and identify potential areas for intervention.
