Study Highlights for December 2010: Archives of Pediatrics & Adolescent Medicine

 

Papers from Archives of Pediatrics & Adolescent Medicine for release December 6 include:

    * Children who attend large group child care facilities before age 2½ appear to develop more respiratory and ear infections at that age, but fewer such illnesses during elementary school years

    * Only about one-fourth of children participating in organized sports—such as baseball, softball or soccer—receive the government-recommended amount of physical activity during team practices

    * Dating violence among adolescents is common and those who physically assault dating partners are also likely to have perpetrated violence involving siblings and peers

    * Infants who are exposed to more television or other forms of media at age 6 months may have lower levels of cognitive and language development at age 14 months, according to a study of 259 mother-infant pairs

    * Exposure to secondhand smoke—as measured by blood levels of cotinine, a biochemical marker of nicotine exposure—appears to be associated with poorer mental health among children (average age 8.3), according to a study of 901 non-smoking children

    * Walking or biking to school appears to be associated with improved cognitive performance among teen girls, according to an assessment of 1,700 adolescents age 13 to 18
