    Excessive weight gain in childhood is a significant risk factor for metabolic dysfunction-associated steatotic liver disease (MASLD).

  • 2

    The study aimed to identify the age at which adiposity impacts liver health, specifically through alanine aminotransferase (ALT) levels at age 8.

  • 3

    Conditional weight, which adjusts for height and previous weight, is a more accurate measure of adiposity related to health risks than BMI.

  • 4

    The study analyzed data from 1322 children, assessing birth weight and annual conditional weight in relation to ALT concentrations.

    Findings from this research could inform interventions for preventing MASLD by identifying critical periods for weight management in children.
