[Reference values of lipid metabolism in childhood (author's transl)]
Insights
This study analyzed cholesterol and triglyceride levels in 949 children, finding no significant differences between healthy and sick groups. Age significantly impacts lipid levels in infancy, with values stabilizing later in childhood.
Area of Science:
- Pediatric lipid metabolism
- Clinical biochemistry
- Diagnostic methods in pediatrics
Context:
- Establishing pediatric reference ranges for lipid parameters is crucial for identifying metabolic disturbances.
- Previous studies have not comprehensively analyzed lipid profiles across all pediatric age groups.
- Comparing healthy children with those having chronic illnesses but normal lipid metabolism provides a robust control group.
Purpose:
- To determine age-specific reference values for cholesterol and triglycerides in children.
- To compare lipid profiles between healthy children and children with chronic illnesses but normal lipid metabolism.
- To establish the highest normal reference values for pediatric cholesterol and triglycerides.
Summary:
- Serum cholesterol and triglycerides were measured in 949 children using enzymatic methods, with lipoprotein patterns analyzed via electrophoresis.
- No significant differences in lipid values were observed between healthy pupils and sick children without lipid metabolism disturbances.
- Cholesterol and triglyceride levels showed a strong age dependency in infancy, stabilizing in later childhood, with established highest reference values.
Impact:
- Provides essential, age-specific reference ranges for pediatric cholesterol and triglycerides.
- Highlights the limited impact of non-lipid-related illnesses on pediatric lipid metabolism.
- Establishes critical upper limits for cholesterol (6.36 mmol/l) and triglycerides (1.74 mmol/l) in childhood for diagnostic purposes.
Abstract:
Sera of 949 children were analyzed for cholesterol and triglycerides by enzymatic methods and for lipoprotein pattern by electrophoresis. For the first time all ages were examined. Two independent collectives were compared: healthy pupils and sick children without disturbances of lipid metabolism. The values of these groups showed no significant difference. In infancy cholesterol and triglycerides levels heavily depend on age, while later in childhood values change little. Highest reference values are 6.36 mmol/l (= 246 mg/dl) for cholesterol and 1.74 mmol/l (= 154 mg/dl) for triglycerides.
