(Reuters Health) – Nearly half of all young women in a small U.S. study said they were poor sleepers, and those who drank sugary coffee beverages and energy drinks tended to have the worst sleep quality.
“Young adulthood is a time of intense change that influences health behaviors,” said Deborah Rohm Young, director of behavioral research at Kaiser Permanente Southern California in Pasadena. “We were specifically interested in sleep quality because not much research has been conducted on sleep and other health behaviors in young adults.”
To explore this question, the researchers analyzed responses from 462 women who had participated in a long-term study as teenagers, beginning in 2006.
In 2015, the women answered a sleep quality questionnaire to rate their sleep duration, how often they wake up during the night, how long they take to fall asleep and any use of sleep medications. Sleep quality scores were calculated based on seven aspects of sleep.
