New York: Children who have trouble sleeping tend to do worse in school than their peers who get a good night`s sleep, a new study suggests.Researchers in Brazil looked at children age seven to 10 who attended Sao Paulo public schools. They found kids with symptoms of sleep disorders or sleep breathing disorders earned lower grades than those without problems sleeping, on average.Thirteen percent of children with difficulty sleeping had failing grades in Portuguese, compared to nine percent of those without sleep problems. Likewise, 25 percent of kids with disrupted sleep had failing math grades, versus eight percent of children without trouble sleeping."Because (symptoms of sleep disorders) and particularly (sleep breathing disorders) are highly prevalent, we suggest that all health professionals and educators become aware of this striking effect and take appropriate actions to solve or mitigate what could very well constitute a public health issue," researchers led by Luciane Bizari Coin de Carvalho from the Universidade Federal de Sao Paulo wrote.
