Compared to the general pediatric population, children with autism have higher rates of co-occurring medical and psychiatric illnesses, yet very little is known about the general health status of adults with autism. The objective of this study was to describe the frequency of psychiatric and medical conditions among a large, diverse, insured population of adults with autism in the US. Participants were adult members of Kaiser Permanente Northern California enrolled from 2008-2012. ASD cases (N=1,507) were adults with ASD diagnoses (ICD-9-CM 299.0, 299.8, 299.9) recorded in medical records on at least 2 separate occasions. Controls (N=15,070) were adults without any ASD diagnoses sampled at a 10:1 ratio and frequency matched to cases on sex and age.Adults with autism had significantly increased rates of all major psychiatric disorders including depression, anxiety, bipolar disorder, obsessive compulsive disorder, schizophrenia, and suicide attempts. Nearly all medical conditions were significantly more common in adults with autism, including immune conditions, GI and sleep disorders, seizure, obesity, dyslipidemia, hypertension, and diabetes. Rarer conditions, such as stroke and Parkinson's disease, were also significantly more common among adults with autism. Future research is needed to understand the social, health care access and biological factors underlying these observations.
We conducted a nested case-control study including 407 cases and 2075 frequency matched controls to investigate the association between maternal infections during pregnancy and risk of autism spectrum disorders (ASD). Cases, controls, and maternal infections were ascertained from Kaiser Permanente Northern California clinical databases. No overall association between diagnoses of any maternal infection during pregnancy and ASD (adjusted odds ratio [ORadj] = 1.15, 95% confidence interval [CI] 0.92 – 1.43). However, women with infections diagnosed during a hospital admission (ORadj= 1.48, 95% CI1.07 – 2.04), particularly bacterial infections (ORadj = 1.58, 95% CI 1.06 – 2.37), were at increased risk of delivering a child with ASD. Multiple infections during pregnancy were associated with ASD (ORadj = 1.36, 95% CI 1.05 – 1.78).
BACKGROUND AND OBJECTIVES:Children with autism spectrum disorder (ASD) have a variety of medical and psychiatric conditions and an increased use of health care services. There is limited information about the prevalence of psychiatric and medical conditions in adolescents and young adults with ASD. Our objective was to describe the frequency of medical and psychiatric conditions in a large population of diverse, insured transition-aged individuals with ASD.
We conducted an online survey of adult health care providers at Kaiser Permanente Northern California and semi-structured interviews with a subset of physicians. The survey assessed providers' ability to recognize autism spectrum disorder (ASD), asked them to rate their autism knowledge, comfort level in treating affected patients, and evaluated training and resource needs. 922 providers completed the survey (response rate 25.3 %), and 9 were interviewed by telephone regarding their autism training and experiences caring for patients with autism. Most providers reported lacking skills and tools to care for this adult patient population. A high proportion of adult providers were not aware that they had patients with ASD. These findings underscore the need to educate physicians caring for adults with ASD.
