Psychological Distress Less Common Among Parents
It may be hard to believe, but a new U.S. study says parents are less likely to suffer serious psychological distress than non-parents.
Researchers at RTI International in North Carolina analyzed data on more than 33,000 American adults, ages 18 to 49, who took part in the 2002 National Survey on Drug Use and Health. They found that nine percent of parents had experienced serious psychological distress in the past year, compared to 12 percent of non-parents, ABC News reported.
Of all the adults, younger women with lower incomes were most likely to experience serious psychological distress, the study found.
In explaining the difference between parents and non-parents, the researchers said parents with a strong social support network of family and friends may recover more quickly from psychological problems, ABC News reported.

Treadmills Help Down Syndrome Babies Walk Earlier
Compared to traditional therapies, treadmills can help infants with Down syndrome learn to walk months earlier, says a University of Michigan study published in the October issue of the journal Physical Therapy.
The study included 30 babies with Down syndrome who were walked on a treadmill for eight minutes a day, five days a week, Agence France-Presse reported. As a result, the babies learned to walk four to five months earlier than usual 24 to 28 months it takes using traditional physical therapy alone.
Helping babies with Down syndrome learn to walk earlier can boost their motor skills, social skills, perception and spatial cognition, explained study author Dale Ulrich of the university's division of kineisiology.
"The key is if we can get them to walk earlier and better, then they can explore their environment earlier and when you start to explore, you learn about the world around you," Ulrich told AFP. "Walking is a critical factor in development in every other domain."
