    Summary

    Cholesterol levels in children change during puberty. Boys experience significant decreases in HDL cholesterol and increases in cholesterol ratios post-puberty, unlike girls.

    Area of Science:

    • Pediatric Endocrinology
    • Lipid Metabolism
    • Cardiovascular Health

    Context:

    • Understanding lipid profile changes during childhood and adolescence is crucial for assessing cardiovascular risk.
    • Prepubertal and pubertal lipid concentrations exhibit sex-specific patterns that evolve with developmental stages.

    Purpose:

    • To investigate the sex-specific changes in lipid profiles, including total cholesterol, HDL cholesterol, LDL + VLDL cholesterol, and their ratios, from prepuberty through completed puberty.

    Summary:

    • In prepubertal children, lipid profiles are similar between sexes, with slight variations in ratios. During puberty, boys show a more pronounced decrease in total cholesterol and a significant drop in HDL cholesterol, while girls maintain stable HDL levels.
    • Post-puberty, boys exhibit significantly increased total cholesterol/HDL cholesterol and total cholesterol/LDL + VLDL cholesterol ratios compared to prepubertal levels, whereas girls show no significant changes in these ratios. Triglyceride levels increase significantly in boys during puberty.

    Impact:

    • These findings highlight critical sex-differentiated shifts in lipid metabolism during adolescence.
    • Provides essential data for monitoring pediatric lipid health and identifying potential long-term cardiovascular risks.
    • Informs clinical guidelines for managing dyslipidemia in children and adolescents.
