NEW YORK (Reuters Life!) - In good news for parents of children who talk late, an Australian study shows that a slow start on language is unlikely to have lingering effects on the children's mental health.

Andrew Whitehouse and colleagues at the University of Western Australia, followed late talkers into their teens in an unusual long-term study and found that they were no more likely to be shy, depressed or aggressive than their peers as they great up.

"Expressive vocabulary delay at the age of 2 years is not in itself a risk factor for later behavioral and emotional disturbances," the group wrote in Pediatrics.

That means a "wait-and-see" approach may be just fine for toddlers with a language lag, as long as they develop typically in other areas.

Between 7 to 18 percent of children have language delays at two years, although most catch up by the time they start school. Some research has suggested that these toddlers may face psychological problems, but whether that matters later on has been unclear.

The study followed more than 1,400 two-year-olds whose parents had filled out a language development survey asking about the words their child would use spontaneously. A two-year-old typically says a few hundred words, but there is a lot of variation.

About one of every 10 two-year-olds in the study was a late talker, scoring in the lowest 15 percent on a list of 310 common words.

The late-talking toddlers also appeared to have more psychological problems, according to questions on a child behavior checklist that parents answered.

For instance, 13 percent of the late talkers had "internalizing" behavior -- such as being shy, sad or underactive -- compared to 8 percent of their peers who were "faster" talkers.   Continued...
