Racial and Ethnic Differences in Behavioral Problems and Medication Use Among Children With Autism Spectrum Disorders

Prevalence of ADHD among Black Youth Compared to White, Latino and Asian Youth: A Meta-Analysis

OBJECTIVE

To systematically review the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) among Black children and adolescents compared to White, Latino and Asian children and adolescents.

METHOD

Peer-reviewed articles were identified in seven databases and included if they reported prevalence of ADHD among Black children and adolescents living in a minority context and compared rates to at least one of White, Latino or Asian samples. A total of 7050 articles were retrieved and 155 articles were subjected to full evaluation. Twenty-three studies representing 26 independent samples were included.

RESULTS

The pooled sample size was n = 218,445 (k = 26), n = 835,505 (k = 25), n = 493,417 (k = 24), and n = 66,413 (k = 7) of Black, White, Latino, and Asian participants, respectively. Pooled prevalence rate of ADHD was 15.9% (95%CI 11.6% - 20.7%) among Black children and adolescents, 16.6% (95%CI 11.6% - 22.2%) among Whites, 10.1% (95%CI 6.9% - 13.8%) among Latinos and 12.4% (95%CI 1.4% - 31.8%) among Asians. There was no significant difference in prevalence between ethnic groups, whereas both Black and White children and adolescents had marginally statistically significant higher prevalence than Asians. The results of a meta-regression analysis showed no moderating effects of the type of sample and the year of publication of studies. A significant publication bias was observed, suggesting that other moderators were not identified in the present systematic review.

CONCLUSION

In contrast to the assertion in the DSM-5 that clinical identification among Black children and adolescents is lower than among White children and adolescents, the present meta-analysis suggests similar rates of ADHD among these two groups. The importance of considering cultural appropriateness of assessment tools and processes is emphasized.

Pediatric and psychiatric models of autism care in Mexico: Differences in diagnostic tools and prescribed interventions

Low- and middle-income countries face heterogeneity in the way clinicians' approach Autism Spectrum Disorder (ASD) diagnosis and treatment. The current study analyzes the diagnostic tools, laboratory tests, pharmacological and psychosocial interventions received by patients during the steps to diagnosis and treatment of two specialized care centers. Researchers interviewed families with a child with ASD receiving services at either a child psychiatric or a pediatric hospital. Of the total sample, 47% reported clinicians not using a diagnostic tool, 20% reported not receiving any psychosocial intervention, and 88% reported receiving a pharmacological prescription. Patients at the pediatric hospital were more likely to receive interventions with some components of Applied Behavioral Analysis, Early Start Denver Model, Treatment and Education of Autistic and Related Communication Handicapped Children, and Sensory integration therapy; while patients at the psychiatric hospital were more likely to undergo learning, daily living skills, and socialization therapies. Patients at the psychiatric hospital received significantly more requests to obtain auditory and vision tests whilst genetic testing and imaging were more common in the pediatric hospital. The range and variability in terms of diagnostic tools, laboratory tests, and treatment options observed for both sites reflect a lack of consensus. Recommendations to improve ASD diagnostic and treatment in Mexico are given.

Racial/Ethnic Differences in Psychiatric and Medical Diagnoses Among Autistic Adults

Background

Racial/ethnic disparities in access to diagnostic services are pervasive for autistic children. However, a few studies have examined racial/ethnic health disparities among autistic adults, who commonly experience higher rates of health conditions than non-autistic adults. We aimed at examining the intersection of autism and race/ethnicity in association with psychiatric and medical diagnoses.

Methods

The study population included adult members of Kaiser Permanente Northern California enrolled from 2008 to 2012. We ascertained 1507 adults who had an autism diagnosis documented in their electronic medical records. We sampled a matched control group of adults without an autism diagnosis (N = 15,070) at a 10:1 ratio. Our sample was 46% White, 17% Hispanic, 16% Asian, 7% Black, and 14% other race/ethnicity. We compared health diagnoses (a) between autistic and non-autistic adults within strata of race/ethnicity and (b) across race/ethnicity within strata of autistic and non-autistic adults. Lastly, we examined the interaction between autism and race/ethnicity on both multiplicative and additive scales.

Results

Autistic adults were more likely to be diagnosed with most medical and psychiatric conditions compared with their non-autistic counterparts of the same race/ethnicity. Among autistic adults, Black, Hispanic, and Asian adults were less likely to be diagnosed with psychiatric conditions and Black and Hispanic autistic adults were more likely to be diagnosed with obesity than their White counterparts. In interaction models, we found that adults who were Black and autistic were disproportionately less likely to be diagnosed with psychiatric conditions and autoimmune disease and more likely to be diagnosed with hypertension than expected.

Conclusion

Health vulnerabilities may be compounded at the intersection of autism and race/ethnicity. Future research should continue to apply an intersectional lens toward understanding and addressing these disparities. Our findings likely underestimate the health disparities that exist in uninsured autistic adults and those living in other parts of the United States.

Autism presentation in female and Black populations: Examining the roles of identity, theory, and systemic inequalities

LAY ABSTRACT

Although the prevalence of autism has been rising in recent years, disparities in diagnosis still remain. Female and Black populations in the United States are diagnosed later, are more likely to have an intellectual disability, and are excluded from research as well as services designed for autistic individuals. Autistic Black girls are effectively invisible in the current scientific literature. Intersectional theory, which looks at a person as a whole, examines models that are inclusive toward diverse gender, ability, and racial/ethnic backgrounds. This theory may be a useful approach to clinical and research work with autism so that practitioners may be most effective for the whole population of autistic people. The authors recommend research focusing on inclusion of autistic populations with intellectual disability and research studies that include evaluations as part of the procedure. Clinically, the authors recommend a focus on screening all young children for autism and improving provider knowledge in working with diverse autistic populations.

Factors associated with use of medication for behavioral challenges in adults with intellectual and developmental disability

BACKGROUND/AIMS

Persons with intellectual or developmental disabilities and who exhibit challenging behaviors are often prescribed medication to control behavior. Little is known about the environmental factors that may be associated with taking these medications.

METHODS AND OUTCOMES

This study examined the association between individual and intermediate or environmental factors and the documented use of medication for clients with intellectual or developmental disabilities (IDD) who exhibit challenging behavior, using the 2014-15 National Core Indicators Adult Consumer Survey dataset.

RESULTS AND CONCLUSIONS

Individual-level variables associated with a higher likelihood of taking medication for persons with IDD exhibiting challenging behaviors included being of younger age, male gender, having moderate or severe intellectual disability, being ambulatory, communicating verbally, having a behavioral plan, requiring support for behavioral challenges, and having a history of mental illness. Environment-level variables included infrequently eating out and having less everyday choice. This study found that restrictions in opportunities to make choices in their life was associated with a greater likelihood of being on a medication for persons with IDD who exhibit challenging behavior. Living in group home settings also increased the likelihood of medication use. A limitation of the study is a lack of information on why medications were prescribed and whether they were intended to treat the challenging behavior.

IMPLICATIONS

This work has important implications for health providers, as addressing malleable social factors may provide an avenue for reducing challenging behaviors without the need for medication.

Clinical Profiles of Black and White Children Referred for Autism Diagnosis

Black children with autism are diagnosed at an older age. Whether or not late detection is paralleled by differing clinical presentation is not known. We evaluated symptom profiles of 245 Black and 488 sex- and age-matched White non-Hispanic participants (82.8% male; mean age: 4.2 years) referred for ASD diagnosis. Both groups showed similar overall levels of autistic symptoms. Black children had significantly but slightly lower scores on cognitive tests and on the Vineland communication domain than White children. Groups were comparable on internalizing and externalizing co-occurring problems. Given the largely similar clinical profiles, clinical differences in initial presentation may not be a primary reason for Black/White disparities in diagnostic and services use. Limitations of a cross-sectional referred sample are acknowledged.
