[The lipid status, insulinemia and fat mass in 40 children with essential obesity]
Insights
Childhood obesity is linked to higher cholesterol and insulin levels, increasing cardiovascular risk. However, simple skinfold measurements may not accurately predict these risks in obese children.
Area of Science:
- Pediatric Endocrinology
- Cardiovascular Health
- Body Composition Analysis
Context:
- Childhood obesity is a growing public health concern with potential long-term cardiovascular implications.
- Obese children often exhibit dyslipidemia and hyperinsulinemia, risk factors for atherosclerosis.
- Accurate assessment of body composition is crucial for identifying at-risk individuals.
Purpose:
- To evaluate the correlation between body composition, serum lipids, and insulin levels in obese children.
- To investigate the utility of skinfold measurements in assessing metabolic risk factors in pediatric obesity.
Summary:
- Forty obese children (aged 6-14 years) underwent assessment of plasma insulin, serum lipids, and body composition via skinfold measurements.
- No significant correlation was found between insulin, lipids, and overall fat mass percentage.
- The study suggests that skinfold measurements alone may not differentiate between subcutaneous and intra-abdominal fat, limiting their ability to predict metabolic risks associated with abdominal obesity.
Impact:
- Highlights the limitations of simple anthropometric measures like skinfold thickness in assessing cardiovascular risk in obese children.
- Underscores the importance of differentiating fat distribution (e.g., abdominal vs. general obesity) for accurate risk stratification.
- Suggests that more sophisticated methods may be needed to accurately identify metabolic risks in pediatric obesity, guiding targeted interventions.
Abstract:
Obesity is usually defined on the basis of body composition measurements. Body composition can be assessed using elaborate methods or anthropometry. Obese children are characterized by increased serum total cholesterol and triglycerides, reduced high-density-lipoprotein(HDL)-cholesterol concentrations, and hyperinsulinemia. Such a metabolic profile may create favorable conditions for atherogenesis and cardiovascular disease later in life. In fourty obese children aged 6-14 years were evaluated plasma insulin after OGTT, serum lipids and body composition. The correlation analysis between insulin, lipids and fat mass (%), based on skinfold measurements was not significative. These results are possible because with skinfold measurements are not separated the subcutaneous and intraabdominal compartments; infarct, only abdominal obesity is associated with the increased risk factors (hyperinsulinemia, hyperlipidemia, ecc.).
