Perceived discrimination and cardiovascular risk factors in mid-life women: results from Project Viva, a longitudinal cohort in the USA.

In adjusted models, a 10-point increment in total WEDS score was associated with a higher risk of obesity (RR=1.40, 95% CI 1.10 to 1.79), higher mean BMI (β=1.62 kg/m 2 , 95% CI 0.50 to 2.74), shorter mean nightly sleep duration (β=−0.23 hours, 95% CI −0.41 to –0.06) and higher PROMIS sleep-related impairment t-score (β=2.28, 95% CI 0.95 to 3.61); the associations with nightly sleep duration <7 hours (RR=1.13, 95% CI 0.99 to 1.29) and higher sleep disturbance t-score (β=0.99, 95% CI −0.01 to 1.99) were marginally significant ( figure 1 , table 2 , table 3 ).
