In addition, the clearly observed educational inequalities in CRP among women (model 1, OR: 0.66 (0.55-0.79)) seem to be largely explained by obesity-related measures (model 3, OR: 0.78 (0.64-0.93)), and are in line with previous studies suggesting large SEP inequalities in obesity among Russian women [41]. The gene discussed is CRP; the disease is obesity due to melanocortin 4 receptor deficiency.
