A growing body of research has identified circadian-rhythm disruption as a risk factor for metabolic health. However, the underlying biological basis remains complex, and complete molecular mechanisms are unknown. There is emerging evidence from animal and human research to suggest that the expression of core circadian genes, such as circadian locomotor output cycles kaput gene (CLOCK), brain and muscle ARNT-Like 1 gene (BMAL1), period (PER), and cyptochrome (CRY), and the consequent expression of hundreds of circadian output genes are integral to the regulation of cellular metabolism.

Thus, a better understanding is needed of the behavioral, economic, and geographic factors that influence obesity risk factors such as eating behaviors. We used a discrete choice experiment to evaluate the impact of different meal attributes on meal choice and to test whether the relative importance of these attributes varied by SES and race/ethnicity.

Thus, we examined the association between smoking cessation and subsequent stroke risk and whether the association was modified by concurrent weight gain. In 2017, we analyzed data from 109,498 postmenopausal US women enrolled in the Women's Health Initiative from 1993 to 1998.

Methods: A prospective cohort study was designed among young and middle-aged US men (n = 925) and women (n = 1193). Fasting serum glucose and insulin were measured five times in 1985-2005.
