Abstract
Screening only those with a positive family history misses many children with hypercholesterolemia. This study investigated whether sensitivity improved by adding obesity as a criterion when screening children for cholesterol. During a two-year period screenings were conducted on 506 inner-city subjects aged 5-19. Demographic, clinical, and dietary information was also recorded. Mean age of participants was 11 ± 4 years; 52 percent were female, 53 percent black, 39 percent Hispanic, and 8 percent other. Mean cholesterol level was 4.14 mmol/l (160 mg/dl). In multivariate analysis obesity was an independent risk factor for hypercholesterolemia, F = 23.14, p < 0.001. The sensitivity of obesity as a screening tool for hypercholesterolemia was better than that for positive family history (42 vs. 24 percent, respectively). Combining the two improved the sensitivity to 49 percent. The authors recommend expanding the indications for screening children to include obesity, in addition to positive family history of hypercholesterolemia or premature cardiovascular disease.
