Obese participants showed a higher incidence of metabolic risk compared to those of overweight, including diabetes (A1C: 97.8 vs. 93.3%), hypertension (HTN: 41.1 vs. 15.6%), anemia (low Hb: 23.0 vs. 14.0 g/dL), low LDLC (60.0 vs. 55.0%), hypothyroidism (F. T4: 83.1 vs. 82.8%), hypovitaminosis-D (Vit.D: 65.6 vs. 64.3%) and hypocreatinemia (low Cr: 42.7 vs. 24.5%) per each respective population. Here, GSTM1 is linked to anemia (phenotype).
