More specifically, for women, having the last child before age 25 was associated with a higher level of CRP (B = 0.239, p < .05), a higher cholesterol ratio (B = 0.136, p < .05), and higher risk of obesity (OR = 1.334, CI = [1.01, 1.77]). This evidence concerns the gene CRP and obesity due to melanocortin 4 receptor deficiency.
