Serum cholesterol, triglyceride, VLDL-c, LDL-c, and HDL-c levels in healthy children

Area of Science:

• Pediatric lipidology
• Clinical biochemistry
• Diagnostic reference values

Background:

• Accurate reference ranges for serum lipids in children are crucial for diagnosing dyslipidemias.
• Existing data may not cover the full pediatric age spectrum or specific lipid fractions comprehensively.

Purpose of the Study:

• To determine and establish normal reference values for serum cholesterol, triglyceride, VLDL-C, LDL-C, and HDL-C in healthy children aged 0-15 years.
• To provide essential data for diagnostic testing and clinical interpretation in pediatric lipid disorders.

Main Methods:

• A cross-sectional study involving 420 healthy children (209 males, 211 females) aged 0-15 years.
• Participants were categorized into four age groups: 0-12 months, 13 months-6 years, 7-11 years, and 12-15 years.
• Serum levels of total cholesterol, triglycerides, VLDL-C, LDL-C, and HDL-C were measured and analyzed.

Main Results:

• Mean serum lipid levels varied across age groups, with significant increases in cholesterol, HDL-C, and LDL-C observed in older children.
• No statistically significant differences in serum lipid levels were found between males and females across all age groups.
• Specific mean values for each lipid fraction were documented for the four age cohorts.

Conclusions:

• This study provides age-specific reference values for key serum lipids in healthy children.
• The findings highlight the influence of age on pediatric lipid profiles and confirm the absence of sex-based differences.
• These established values can aid clinicians in the accurate diagnosis and management of lipid abnormalities in pediatric populations.
