A genetically informed cross‐lagged twin study of the longitudinal association between addiction‐related behaviors and obesity

Key Points

• To explore how genetic factors affect the relationship between obesity and addiction-related behaviors over time.
• Used a cross-lagged twin study design
• Analyzed the genetic influences on body mass index and loss of control eating
• Assessed longitudinal data to establish associations between behaviors over time
• Higher body mass index at a younger age linked to increased risk of loss of control eating later
• Genetic factors play a significant role in both obesity and disordered eating behaviors
