Among maternal characteristics, it is observed that IL-6 has a positive correlation with previous exposure to malaria (Pearson, r = 0.21; P = 0.001) and with parasitemia (r = 0.45; P < 0.001), and a negative correlation with maternal weight gain (r = -0.14; P = 0.050); IL-8 also has a positive correlation with parasitemia (r = 0.32; P = 0.002). The gene discussed is IL6; the disease is parasitic infectious disease.
