Why the study?

Does black race increase the risk of cerebral infarction compared to white race after adjusting for stroke risk factors?

Key Points

To determine whether Black adults experience an increased risk of cerebral infarction compared to White adults after adjusting for stroke risk factors and sociodemographic variables.
Prospective cohort study analyzing 8,203 White and 1,362 Black participants from the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study over a 13-year period.
Tracked incident cerebral infarction events (538 in Whites, 122 in Blacks) and adjusted for age, sex, education, heart disease history, diabetes, systolic blood pressure, hypertension treatment, Quetelet index, and serum hemoglobin and magnesium levels.
The racial disparity in cerebral infarction risk significantly differed by age (P = .007 for race-age interaction), with unadjusted relative risk elevated in Black adults aged 35 to 44 years (RR 2.62; 95% CI, 1.23 to 5.57) but not in those older than 64 years (RR 1.14; 95% CI, 0.90 to 1.46).
Multivariable adjustment attenuated the relative risk of cerebral infarction to 2.07 (95% CI, 0.97 to 4.42) among younger Black adults and to 0.82 (95% CI, 0.29 to 2.33) in older Black adults.

Structured PICO

Does black race increase the risk of cerebral infarction compared to white race after adjusting for stroke risk factors?

Population

9,565 participants (8,203 whites and 1,362 blacks) from the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study

Intervention

Black race (observational exposure)

Comparator

White race

Outcome

Cerebral infarction over 13-year follow-uphard clinical

The increased risk of cerebral infarction in Black individuals is largely explained by a higher prevalence of stroke risk factors, though younger Black individuals may retain a residual increased risk.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Supports risk factor focus in young blacks; leaves open residual disparity for further study.
