To determine the effect of obesity in children on CCL2 levels, the lean and obese CCL2 groups were compared, and there was a statistically significant difference in CCL2 levels between lean and obese children when analyzed as a group (150.4 ± 61.85 pg/ml versus 112.7 ± 38 pg/ml) with a main effect for the OW-LF group (F (3,32) = 3.2, p = 0.034) when compared to L-LF group (Figure 1). The gene discussed is CCL2; the disease is obesity due to melanocortin 4 receptor deficiency.
