Prevalence and Risk Factors Associated With Attention-Deficit/Hyperactivity Disorder Among US Black Individuals: A Systematic Review and Meta-analysis
Open accessAbstract
Importance: As stated in the DSM-5, it is generally reported that the prevalence of attention-deficit/hyperactivity disorder (ADHD) is lower among Black individuals compared with the general population. However, Black individuals living in countries where they are considered a minority population group (eg, in Northern America and Europe) are underrepresented in studies evaluating ADHD. Objective: To estimate the pooled prevalence of ADHD and identify associated risk factors among US Black individuals. Data Sources: This systematic review and meta-analysis identified peer-reviewed studies published until October 18, 2019, using the APA PsycInfo, MEDLINE, Embase, Cochrane CENTRAL, CINAHL, ERIC, and Education Source databases. Study Selection: Eligible trials were published in French or English, had empirical data on the prevalence of ADHD in samples or subsamples of Black people, and were conducted in countries with Black minority populations. All studies were assessed and passed quality evaluation. Data Extraction and Synthesis: The PRISMA guideline was used for extracting and reporting data. Random-effects meta-analyses were generated to estimate the prevalence of ADHD among Black individuals using the metafor package in R. Main Outcomes and Measures: Prevalence and risk factors associated with ADHD among Black individuals were identified. Results: A total of 24 independent samples and subsamples from 21 studies published between 1979 and 2020 (154 818 Black participants) were included in this systematic review and meta-analysis. All included studies were conducted in the US. Two studies were conducted assessing adults (aged 18 years or older), 8 assessing children (0-12 years), 1 assessing adolescents (aged 13-17 years), and 13 assessing both children and adolescents. The pooled prevalence of ADHD was 14.54% (95% CI, 10.64%-19.56%). In a narrative review of the studies in this analysis, some studies found risk factors associated with ADHD, such as sociodemographic characteristics (age, sex, race, and socioeconomic status), familial factors, environmental factors, and risk behaviors, but the data did not permit a moderation analysis to assess these findings in this study. Conclusions and Relevance: Contrary to what is stated in the DSM-5, the results of this systematic review and meta-analysis suggest that Black individuals are at higher risk for ADHD diagnoses than the general US population. These results highlight a need to increase ADHD assessment and monitoring among Black individuals from different social backgrounds. They also higlight the importance of establishing accurate diagnoses and culturally appropriate care.

ADHD prevalence among U.S. Black youths under 18 is 14%.
“A meta-analysis of 19 studies encompassing over 150,000 U.S. Black youths under 18 years old reported an ADHD prevalence rate of 14 percent.”

The Results report a pooled ADHD prevalence of 13.87% for 19 studies assessing Black people younger than 18, which rounds to 14%. However, the reported total of 154,818 participants covers all 21 studies, including adult samples; it does not establish that the 19-study youth analysis encompassed over 150,000 participants.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
