Objective:

To estimate sex-specific effects of limiting sugar-sweetened beverages (SSBs) and 100% fruit juice intake throughout childhood on insulin resistance, central adiposity, and glycemic outcomes in late adolescence, focusing on hypothetical interventions.

Key Findings:
  • Limiting SSBs to 1 serving weekly could reduce HOMA-IR by 0.28 units in males (95% CI, −0.61 to 0.02).
  • In males, waist circumference could decrease by 1.91 cm (95% CI, −3.79 to −0.05) and truncal fat mass by 0.64 kg (95% CI, −1.33 to 0.05).
  • Fasting glucose could decrease by 1.02 mg/dL in males with limited SSB intake (95% CI, −2.40 to 0.35).
  • Effect estimates for females were near zero and less precise.
  • Effects of limiting 100% fruit juice were small and imprecise in both sexes.
Interpretation:

Limiting SSB intake in childhood may have modest benefits on insulin resistance and central adiposity in males, while effects in females are negligible.

Limitations:
  • Study population consisted of low consumers of SSBs, limiting generalizability.
  • Observational data may not fully capture causal relationships.
  • Effect estimates for fruit juice were imprecise, indicating uncertainty.
  • Potential biases in self-reported data may affect the accuracy of beverage intake.
Conclusion:

Reducing SSB intake in childhood may yield small improvements in metabolic health outcomes in adolescent males, highlighting the need for targeted interventions for both sexes.
