What is the clinical evidence from this study?

Study design: Observational. Population: Hypercholesterolemia (n=2504). Intervention: Diagnosis and dietary intervention. Primary outcome: Changes in total cholesterol, LDL-C, HDL-C, and triglyceride levels (p=<0.05).

What question did this study set out to answer?

The Impact of Dietary Intervention on HDL and LDL Cholesterol Levels in a Pediatric Population

Q: What are the key findings of this study?

Diagnosis and dietary intervention in children with elevated cholesterol led to significant decreases in total cholesterol and LDL-C, and increases in HDL-C and triglycerides (P<0.05).

Key result

Dietary intervention in hypercholesterolemic children is linked to significantly reduced total cholesterol and LDL-C.

P<0.05
n=2,504

Why the study?

Does diagnosis and dietary intervention improve lipid profiles in children with elevated cholesterol?

Population

2504 children screened for cholesterol levels, of which 709 had elevated cholesterol levels.

Implication

Diagnosis and dietary intervention in children with elevated cholesterol led to significant improvements in total cholesterol and LDL-C levels, though safety regarding growth remains to be evaluated.

Key Points

To determine the effect of dietary intervention on cholesterol levels in a pediatric population and identify those with elevated cholesterol.
Screened 2504 children for cholesterol levels between July 1989 and April 1991.
Identified 709 children with elevated cholesterol levels over the 75th percentile.
Recorded changes in lipid fractions after dietary advice was given.
Correlated fingerstick screening method with laboratory venipuncture method.
28% of children screened had elevated cholesterol levels.
Intervention led to decreases in LDL and total cholesterol and increases in HDL and triglycerides.
70% of children had laboratory lipid measures within 10% of initial fingerstick screening results.

Does diagnosis and dietary intervention improve lipid profiles in children with elevated cholesterol?

Population

2,504 children screened for elevated cholesterol, of whom 709 with hypercholesterolemia were followed to record alterations in lipid fractions after diagnosis and dietary advice.

Exposure

Diagnosis of hypercholesterolemia and dietary intervention/advice

Outcome

Alterations in total cholesterol level and lipid fractions (LDL-C, HDL-C, triglyceride) after diagnosis and interventionsurrogate

Main Result

p-value: p=<0.05

Diagnosis and dietary intervention in children with elevated cholesterol led to significant improvements in total cholesterol and LDL-C levels, though safety regarding growth remains to be evaluated.

Limitations

Potential for growth failure due to overzealous restriction of fat and cholesterol-rich foods needs to be analyzed before definitive conclusions can be made.
Changes in lipid levels cannot be attributed to a particular intervention due to untargeted interventions
Potential for growth failure due to overzealous restriction of fat and cholesterol rich foods not analyzed

Karen White (1992) conducted an observational in Hypercholesterolemia (n=2,504). Diagnosis and dietary intervention was evaluated on Changes in total cholesterol, LDL-C, HDL-C, and triglyceride levels (p=<0.05). Diagnosis and dietary intervention in children with elevated cholesterol led to significant decreases in total cholesterol and LDL-C, and increases in HDL-C and triglycerides (P<0.05).
