Study: U.S. women more likely than men to say they feel worried

(CNN) -- U.S. women are more likely than men to say they feel worried, nervous or anxious.

That's according to a survey from the Centers for Disease Control and Prevention.

The survey was conducted in 2010 and 2011.

22% of women said they felt worried, nervous, or anxious daily or weekly, compared to 16% of men.

According to the study, younger and middle-age men and women felt those feelings the most.

Older adults were a little happier and less stressed.

Among those age 75 and older, 16% of women often felt worried, nervous or anxious, compared with 11% of men.

The study is published in the CDC's Morbidity and Mortality Weekly Report.
