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
aggression1, depression, and suicidal thoughts in adolescents, the relationship had not been evaluated in younger children. A new study scheduled for publication in The Journal of Pediatrics finds that aggression, attention problems, and
withdrawal2 behavior are all associated with soft drink consumption in young children. Shakira Suglia, ScD, and colleagues from Columbia University's Mailman School of Public Health, University of Vermont, and Harvard School of Public Health assessed approximately 3,000 5-year-old children
enrolled3 in the Fragile Families and Child Wellbeing Study, a
prospective4 birth cohort that follows mother-child pairs from 20 large U.S. cities. Mothers reported their child's soft drink consumption and completed the Child Behavior Checklist based on their child's behavior during the previous two months. The researchers found that 43% of the children consumed at least 1 serving of soft drinks per day, and 4% consumed 4 or more.
Aggression, withdrawal, and attention problems were associated with
soda5 consumption. Even after adjusting for
sociodemographic(社会人口的) factors,
maternal6 depression, intimate partner violence, and
paternal7 incarceration8, any soft drink consumption was associated with increased aggressive behavior. Children who drank 4 or more soft drinks per day were more than twice as likely to destroy things belonging to others, get into fights, and
physically9 attack people.
According to Dr. Suglia, "We found that the child's aggressive behavior score increased with every increase in soft drinks servings per day." Although this study cannot identify the exact nature of the association between soft drink consumption and problem behaviors, limiting or eliminating a child's soft drink consumption may reduce behavioral problems.
