Compared with women whose sleep duration didn't change, those with either increases or decreases of 2 or more hours had higher body mass indexes (BMIs), less physical activity, and poorer diet quality. They were also more likely to snore, to smoke, to take antidepressants, and to have hypertension, hypercholesterolemia, and a family history of diabetes. More of them had also performed shift work for 5 or more years.
