Sugar-Sweetened Beverage Consumption Is Adversely Associated with Childhood Attention Deficit/Hyperactivity Disorder

Area of Science:

• Neuroscience
• Pediatrics
• Nutritional Psychiatry

Background:

• Attention deficit/hyperactivity disorder (ADHD) is a prevalent childhood neurobehavioral condition.
• Existing evidence on the impact of sugar-sweetened beverages (SSBs) on mental health, particularly ADHD, remains inconclusive.
• Previous research suggests a potential association between high SSB intake and attention problems in children.

Purpose of the Study:

• To investigate the hypothesis that SSB consumption is associated with ADHD in children.
• To determine if a dose-response relationship exists between SSB intake and ADHD diagnosis.
• To explore the correlation between SSB consumption and ADHD, controlling for various covariates.

Main Methods:

• A case-control study involving 173 children diagnosed with ADHD and 159 non-ADHD controls, aged 4-15 years.
• Data collection via questionnaires on SSB consumption, socio-demographics, lifestyle, and maternal pregnancy characteristics.
• Analysis included blood lead levels and polymorphisms of DRD4 and DAT1 genes.

Main Results:

• A significant dose-response relationship was observed between SSB consumption and ADHD.
• Children with moderate and high SSB intake had 1.36 and 3.69 increased odds of ADHD, respectively, compared to non-consumers (p for trend < 0.05).
• These findings persisted after adjusting for covariates and remained significant when excluding females.

Conclusions:

• SSB consumption shows an adverse correlation with ADHD in children.
• A clear dose-response effect indicates that higher SSB intake is associated with a greater likelihood of ADHD.
• Findings underscore the importance of dietary factors, specifically SSB intake, in the context of childhood ADHD.
