q3 i? 31% of the excess poor SCF in women in the highest compared to the lowest quartile of daily racism was attributable to depression (CES-D ≥16), and 41% was attributable to moderate or severe insomnia (ISI ≥15). → Coogan P 2020 q3 i? For institutional racism, 23% of excess poor SCF was attributable to depression and 43% to insomnia. → Coogan P 2020

Mediation analysis using the difference method with the %Mediate macro in the BWHS cohort. The proportion of excess poor SCF attributable to depression was "31% (95% CI 23% to 39%)" and to insomnia "41% (95% CI 33% to 50%)". For institutional racism, the proportions were 23% and 43% respectively. No standardized effect size is printed for the mediation proportions, so impact is null.

"The proportion of excess poor SCF in women in the highest compared to the lowest quartile of daily racism attributable to depression (CES‐D ≥16) was 31% (95% CI 23% to 39%). The equivalent proportion of poor SCF attributable to moderate or severe insomnia (ISI ≥15) was 41% (95% CI 33% to 50%)"
