Women with history of weight cycling have increased rates of sleep problems Women with a history of weight cycling - losing and regaining 10 pounds or more, even once - have increased rates of insomnia and other sleep problems, reports a study in The Journal of Cardiovascular Nursing, official journal of the Preventive Cardiovascular Nurses Association. The journal is published in the Lippincott portfolio by Wolters Kluwer. "History of weight cycling was prospectively associated with several measures of poor sleep, including short sleep duration, worse sleep quality, greater insomnia, greater sleep disturbances, and greater daytime dysfunction among diverse US women across various life stages," according to the new research by Brooke Aggarwal, EdD, MS, FAHA, of Columbia University Vagelos College of Physicians and Surgeons, New York, and colleagues.
