Cell phone use and behavioural problems in young children

This dataset consisted of 28Ã¢â‚¬Ë†745 children with completed Age-7 Questionnaires to December 2008. Results The highest OR for behavioural problems were for children who had both prenatal and postnatal exposure to cell phones compared with children not exposed during either time period. The adjusted effect estimate was 1.5 (95% CI 1.4 to 1.7). Conclusions The findings of a previous publication were replicated in this separate group of participants demonstrating that cell phone use was associated with behavioural problems at age 7
