Sweeteners and Genetics Linked to Early Puberty Risk

TOPLINE:

Sweetener intake, including aspartame and sucralose, was associated with an increased risk for early puberty in children, particularly in those who were genetically predisposed. Sex-specific effects were noted, with sucralose showing a stronger association with early puberty in boys and glycyrrhizin, sucralose, and other sugars in girls.

METHODOLOGY:

  • The prevalence of central precocious puberty, characterized by the early onset of secondary sexual characteristics, is increasing, highlighting the need for research into its causes and prevention strategies.
  • Researchers analyzed a cohort of 1407 children from the Taiwan Pubertal Longitudinal Study to assess the effect of sweetener intake and genetic predisposition on the risk for central precocious puberty.
  • Sweetener intake was evaluated using validated questionnaires and urinary biomarkers.
  • Genetic predisposition was quantified using polygenic risk scores derived from 19 single-nucleotide polymorphisms related to central precocious puberty.
  • Central precocious puberty was diagnosed using clinical, hormonal, and imaging criteria.

TAKEAWAY:

  • Central precocious puberty was diagnosed in 481 children.
  • Aspartame, glycyrrhizin, sucralose, and added sugars showed a significant association with an increased risk for central precocious puberty, especially in children with a genetic predisposition.
  • The consumption of these sweeteners showed a dose-dependent relationship, with a higher intake increasing the risk for central precocious puberty. No significant interaction effects were found between genetic predisposition and sweetener intake.
  • Sex-specific effects were noted; the consumption of sucralose was associated with a higher risk for central precocious puberty in boys, and the consumption of sucralose, glycyrrhizin, and added sugars was associated with a higher risk in girls.

IN PRACTICE:

“The findings indicate that sweetener consumption and genetic predisposition are independently associated with CPP [central precocious puberty] risk. Integrating genetic and dietary assessments could guide prevention strategies for children at heightened risk, mitigating the long-term health impacts of early puberty,” the authors of the study wrote.

“The findings are directly relevant to families, pediatricians, and public health authorities,” the lead author said in a press release. “They suggest that screening for genetic risk and moderating sweetener intake could help prevent early puberty and its long-term health consequences. This could lead to new dietary guidelines or risk-assessment tools for children, supporting healthier development.”

The study was led by Yang-Ching Chen, MD, PhD, Taipei Municipal Wan Fang Hospital and Taipei Medical University, Taipei, Taiwan. It was presented at ENDO 2025: The Endocrine Society Annual Meeting in San Francisco.
