Children Glued to Phones More Likely to Become High-Strung, Depressed Teens

 Study Finds - In case you needed another reason to hold off on buying your child a phone, research shows a troubling connection between childhood screen habits and teenage mental well-being. The eight-year study, which tracked children from elementary school into adolescence, found that kids who racked up more screen time—especially on mobile devices—showed higher levels of stress and depressive symptoms as teenagers.

The study adds to the large body of research that should make parents think twice about unlimited device access, especially as more children experience mental health struggles at an early age. Between one-quarter and one-third of adolescents worldwide experience mental health problems, with symptoms typically first appearing during the teenage years. Researchers now have more concrete evidence about lifestyle factors that might help prevent psychological distress before it takes root.

Study authors used data from the Physical Activity and Nutrition in Children (PANIC) study, which followed 187 Finnish children over eight years, from ages 6-9 into their mid-teens. Researchers regularly checked in on their physical activity, screen time, sleep patterns, and eating habits. When these children reached adolescence (average age 15.8), the researchers assessed their mental health using standardized measures of stress and depression.
