Children Raised with a Cat or Dog Have No Health Advantages over Their Petless Peers, Study Finds

Article excerpt

If your parents never let you have a dog or cat when you were a child, don't feel deprived. Children who grow up with such animals in their homes are not more likely to have better mental or physical health than their petless peers, according to a study published this week in the journal Anthrozoos.

That finding goes against the widely held belief -- expressed both in academic journals and in the popular press -- that pets are beneficial to children's emotional and physical development.

Some animal lovers may not like the new study's results, but they're going to find it difficult to dismiss them. Conducted by researchers at the nonprofit RAND Corporation, the study offers the most comprehensive and rigorous look at this topic to date. For, unlike earlier studies, it used advanced methods of statistical analysis to control for a variety of confounding factors other than pet ownership -- like family wealth -- that are known to be associated with healthier children.

"We could not find evidence that children from families with dogs or cats are better off either in terms of their mental wellbeing or their physical health," said Layla Parast, a study co-author and a statistician at RAND, in a released statement.

"Everyone on the research team was surprised -- we all have or grew up with dogs and cats," she added. "We had essentially assumed from our own personal experiences that there was a connection."

Study details

For the study, Parast and her colleagues analyzed data collected from about 5,200 households with children who participated in the 2003 California Health Interview Survey, the only year that the annual survey has asked participants about whether they had pets. More than 2,200 of those households reported having a dog or a cat (or both) in the house.

The researchers then compared the mental and physical health of the children (as reported by their parents or guardians) in the pet-owning homes with those in the petless ones.

The analysis revealed what earlier studies had reported -- that the children living with dogs and cats tended to have better general health. Their parents were also less likely to report that they were concerned about their children's mood, behavior or ability to learn (although children who had pets were more likely to have attention deficit hyperactivity disorder, or ADHD). …
