...and it would be interesting to know how ACEs fit in, don't you think?
Study participants included 5,502 men and women aged 30 to 79 years, in three racial groups, Black, Hispanic and White.
The researchers found that Black and Hispanic men were more likely than white men to report sleeping less than 5 hours each night (information on sleep duration was only available for men). Poorer men were also likelier to report short sleep. In fact, the authors found that being of a lower socioeconomic class was a greater driver of sleep disparities than were ethnic differences.
They also found that regularly having restless sleep in the baseline interview was associated with a 66 percent increase in the likelihood that a person would be obese five years later. Restless sleep was also associated with a person have a 50 percent greater risk for developing Type 2 diabetes or cardiovascular disease. "While we found that restless sleep was more common in people with obesity, diabetes and heart disease, our data shows that the racial difference we saw in these diseases were not likely caused by these differences in sleep, " said [Rebecca S.] Piccolo.
[Timothy] Monk explained that while the research clearly shows that there are both sleep differences and health differences that occur with race and SES," the health differences are not simply mediated by the sleep differences;" this means, he said, that "there are effects over and above the sleep ones contributing to the health differences observed."
