Children's Health: Lead exposure linked to ADHD in kids ♦ Light exposure and kids' weight: Is there a link? ♦ Interaction during reading is key to language development

Lead exposure linked to ADHD in kids with genetic mutation Exposure to small amounts of lead may contribute to ADHD symptoms in children who have a particular gene mutation, according to new research. The scientists do not purport that lead is the only cause of ADHD symptoms, nor does the research indicate that lead exposure will guarantee an ADHD diagnosis; rather, the study demonstrates that environmental pollutants, such as lead, do play a role in the explanation of ADHD.
Light exposure and kids' weight: Is there a link? Light exposure plays a role in the weight of preschool children, a world-first study reveals. The researchers studied children aged three to five, from six childcare centers, measuring the children's sleep, activity and light exposure for a two week period, along with height and weight to calculate their BMI, then followed up 12-months later.
One in four kids sexually harassed by friends online It's not just strangers who target children online. Kids' own friends are sexually harassing them over the Internet, finds new research. Girls, and kids with low self-control, were more likely to be sexually harassed online. But the biggest surprise was the finding that 24 percent of study participants were sexually harassed over the Internet
Interaction during reading is key to language development A new study finds babies make more speech-like sounds during reading than when playing with puppets or toys -- and mothers are more responsive to these types of sounds while reading to their child than during the other activities.
