In the survey, which took place in 2010 and 2011, about 22 percent of women said they feltworried, nervous, or anxious daily or weekly, compared to 16 percent of men.

In general, these feelings were more common in young and middle-age adults than older people. Previous studies have found older adults are generally happier and less stressed than younger people.

In the new study, participants were asked “How often do you feel worried, nervous, or anxious? Would you say daily, weekly, monthly, a few times a year, or never?”

For men, 17 percent of those ages 18 to 44, and 18 percent of those between 45 and 64 reported daily or weekly worry, nervousness or anxiety. About 23 percent of women ages 18 to 64 said the same.
