The impact of cardiovascular risk factors on cognition in Hispanics and non-Hispanic whites

Pearson correlations and percent variance explained (R²) between Digit Span Backward raw scores and BMI per ethnic group. Among Hispanics, higher BMI was associated with lower Digit Span Backward scores, (r(60) = −0.34, P < 0.01). BMI was not associated with scores among non-Hispanic whites (r(62) = .17, n.s.). Hispanics are represented by open dots and a solid line. Non-Hispanic whites are represented by shaded diamonds and a dashed line.
