A Prospective Ultrasound Study of Whole Blood Metals and Incidence of Uterine Leiomyomata Open
The metal mixture was positively associated with incident UL, but the association was weak and imprecise. We observed a stronger association among vitamin D-deficient participants that was driven by cadmium and mercury. https://doi.org/10.…
Skin tone – a marker of bias known as colorism – in relation to sleep health among African American women Open
People with darker-skin tone are more likely than their lighter-skin counterparts to have less access to health-promoting resources (e.g., economic security; quality housing; favorable neighborhood environment). These adverse conditions ca…
Associations between term cesarean delivery in the first pregnancy and second‐pregnancy preterm delivery Open
Introduction Cesarean delivery has been shown to increase the risk of preterm delivery in future pregnancies. The association could be a direct result of the procedure, or because the indications that led to the cesarean delivery also incr…
Combined oral contraceptive utilization and uterine fibroid incidence: A prospective study in a cohort of African-American women Open
Published associations between combined oral contraceptive use and uterine fibroid development have lacked prospective imaging with ultrasound to distinguish between incident and prevalent fibroids. The Study of Environment, Lifestyle, and…
