Compared with patients who had poor glycemic control (HbA1c≥7%), those with good control (HbA1c<7%) were younger (P = 0.001), had shorter duration of DM (P <0.001), lower waist-hip ratio (P <0.001), higher level of education (P = 0.023), more physical activity (p<0.001) and good adherence to diet (P<0.001).
