16 Aug 2013 --- Americans buy more soft drinks per capita than people in any other country. These drinks are consumed by individuals of all ages, including very young children. Although soft drink consumption is associated with aggression, depression, and suicidal thoughts in adolescents, the relationship had not been evaluated in younger children. A new study by researchers at Columbia University's Mailman School of Public Health, University of Vermont, and Harvard School of Public Health in The Journal of Pediatrics finds that aggression, attention problems, and withdrawal behavior are all associated with soft drink consumption in young children.
