ABSTRACT
Autism spectrum disorder (ASD) is a developmental disorder characterized by deficits in social interaction/communication, restricted interests, and repetitive behaviors. Recent discussions have emerged worldwide regarding the heterogeneity around presentation/etiology and comorbidities. This study aimed to determine the frequency and characteristics of comorbidities among children diagnosed with ASD in Manitoba and to evaluate differences in presentation between those with and without medical comorbidities. We conducted a retrospective chart review of >1900 electronic charts at the only publicly funded referral site for children ≤6 years requiring evaluation for ASD in Manitoba. All children aged 0-6 years diagnosed with ASD at this site between May 2016 and September 2021 were identified. χ2 and t-tests were used to compare groups. Of the total of 1858 children identified, 1452 (78.1%) were boys, 251 (13.5%) were prematurely born, and 539 (29.0%) had ≥1 medical comorbidity. Global developmental delay (GDD) was diagnosed in 428 (23.0%). The age of referral and diagnosis did not differ between groups. Comorbidities were more common among premature children (16.0% vs. 12.5%, p: 0.005) and children with comorbid GDD (34.9% vs. 18.2%, p < 0.001). Neurological comorbidities were most common (37.1%). No sex difference in the overall presence of comorbidities was found (boys = 77.1% vs. 78.5%, p: 0.518); however, girls had a higher incidence of neurological comorbidities, e.g., cerebral palsy, seizures, hypotonia (14.8% vs. 9.64%, p: 0.009), as well as genetic comorbidities (4.92% vs. 2.75%, p: 0.04). The high rates of associated neurological conditions, GDD, and prematurity add heterogeneity to this group leading to potential difficulties with prognosis and service allocation. Primary vs. secondary ASD can be a way of separating individuals based on relevant medical comorbidities.
ABSTRACT
Introduction: Recent studies highlight synergies for families receiving early childhood literacy support from their health care provider and public library, with more reading at home and higher quality book-sharing interactions. Our primary objective was to determine the percentage of Children's Hospital Winnipeg Ambulatory Clinic's patients who had ever used a public library. The clinic has a longstanding early-childhood literacy program and serves remote communities and low-income Winnipeg families. Methods: A structured survey was administered to parents or legal guardians by the first author. It explored library barriers and covariates that might affect library use. Analysis included descriptive statistics and a logistic regression model for predictors of library use. Results: Ninety-seven nearly consecutive surveys were administered, half prior to the COVID-19 pandemic. Most respondents were female, from Winnipeg, and in the two lowest neighbourhood income quintiles. Roughly half (46.4%) of children had used a library. Most respondents wanted health care providers to promote literacy and provide information about public libraries, and more supported in-clinic distribution of books. The number of children per household positively predicted library use, possibly a proxy for experience with community resources. About 2/3 of respondents believed that library fines should be abolished. Most identified other barriers, for example, inconvenient hours, distance, or concerns about COVID-19. Conclusion: Less than half of surveyed families used public libraries, citing multiple barriers, including fines. Moreover, not all health care providers can offer new books and anticipatory guidance. Clinics that promote use of public libraries may therefore represent a low-cost, stand-alone alternative.
