Description

Cardiovascular (CV) disease remains the leading cause of death in the world despite being largely preventable. Risk factors include high levels of visceral fat. Ultrasound has made it possible to measure subcutaneous adipose tissue (SCAT) and visceral adipose tissue (VAT) separately. PURPOSE: To determine the relationship between the Framingham CV risk profile, SCAT, VAT, and physical activity (PA) levels in adults. METHODS: CV risk factors were evaluated in 46 participants, ranging from 19-65 years. To determine the Framingham Score, BMI, total cholesterol, and high-density lipoprotein levels were measured and combined. A 10-cm ultrasound scan was completed by drawing the wand from the umbilicus toward the right hip. Amounts of SCAT and VAT were determined from the scan. Minutes of moderate to vigorous PA were reported from a questionnaire. Pearson Correlations determined the relationships between variables tested at an alpha level of p≤0.05. RESULTS: There were significant, moderate correlations between VAT amounts and the Framingham profile (r=0.445, p=0.002) as well as the amount of SCAT (r=0.509, p=0.00). There was significant negative moderate correlations between the number of minutes of moderate to vigorous PA reported and the Framingham profile (r=-0.440, p=0.002), the amount of VAT measured (r=-0.315, p=0.035), and the amount of SCAT measured (r=-0.301, p=0.045). CONCLUSIONS: Results demonstrated a moderate correlation between the amount of VAT present and CV risk factors, suggesting it may be a viable predictor of future CV disease. Further research is needed to strengthen the use of the VAT measurement in the assessment of CV disease.
