Assessing Gender-Specific Population Impacts of Reducing Sugar-Sweetened Beverages and 100% Fruit Juice Intake in Childhood on Insulin Resistance, Central Fat Distribution, and Glycemic Control in Late Adolescence
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.
Claims-based target trial emulation found no clear association between continued GLP-1 receptor agonist use in early pregnancy and nonlive birth, fetal growth abnormalities, or major congenital malformations.
Revised American Heart Association statement urges a shift toward plant-based protein and flags ongoing uncertainty in fat and alcohol recommendations.
