GH levels showed an inverse correlation with the features of the metabolic syndrome [waist circumference (r = –0.222, P<0.001), systolic blood pressure (r = –0.108, P<0.001), diastolic blood pressure (r = –0.077, P<0.001), triglycerides (r = –0.151, P<0.001), fasting blood glucose (r = –0.028, P<0.018) and HDL-C (r = 0.164, P<0.001)] (Table 2). Here, GH1 is linked to metabolic syndrome.
