Exploring Demographic and Clinical Characteristics of Racially and Ethnically Diverse Youth With Eating Disorders...

To explore the scope of diagnosed eating disorders among Medicaid-insured youth in California, and to describe the demographic characteristics of this population in a repeated annual cross-sectional study design.

California Medicaid claims data were extracted for youth aged 7 to 18 years between January 2014 and December 2016. Participants included all youth who received an eating disorder diagnosis at any point in the study period (N = 8,075). Additional analyses compared youth with eating disorders who were continuously enrolled across all 3 years (n = 4,500) to random subsamples of continuously enrolled youth diagnosed with a mood or anxiety disorder (n = 4,128), a disruptive behavior disorder (n = 4,599), or a psychotic disorder (n = 4,290).

About one-half of youth with eating disorders were Latinx (58.5%, n = 2,634) and indicated Spanish as their preferred language (48.9%, n = 2,199). About one-half (51%, n = 2,301) of eating disorder diagnoses were unspecified. Latinx ethnicity and Spanish language were significantly more frequent among youth with eating disorders than among those with other disorders (F_11.97, F_362.75, p values <.0005).

The first examination of publicly insured youth with eating disorders revealed a highly diverse group of individuals among whom Latinx youth were particularly prevalent. However, past-year national prevalence estimates suggest that most eating disorder cases were undiagnosed.

Eating disorders affect approximately 10% of the US population and lead to serious mental health and medical problems. This study used California Medicaid claims data from 2014 to 2016 to characterize the population of youth aged 7 to 18 years with diagnosed with an eating disorder (N = 8,075). The authors found the prevalence of eating disorders among youth aged 13 to 18 years was about 0.20% across all 3 years of the study, which is far below the expected prevalence and suggests that most eating disorders in youth go undiagnosed. About half of eating disorder diagnoses provided to youth with Medicaid insurance are unspecified, which may hinder receipt of appropriate treatment. Of youth with an eating disorder, about half were Latinx and reported Spanish as their preferred language. The authors also found differences in the prevalences of eating disorder diagnoses when analyzing youth by age, sex, and ethnicity. These results suggest that more standardized screening and assessment is needed to improve eating disorders detection and diagnosis, particularly for minoritized youth.
