Increased exercise is associated with reduced insulin resistance and cardiovascular risk factors in individuals with newly diagnosed diabetes

Abstract

Objective To identify the relationship between physical activity,insulin resistance and cardiovascular risk in individuals with different glucose tolerance status and to provide evidence for exercise intervention in people with different glucose tolerance status. Methods A total of 691 patients with different glucose metabolism status were recruited as subjects of the research. Spearman correlation analysis was used to study the relationship between exercise frequency and insulin resistance, insulin sensitivity, neck circumference (NC) and neck circumference height ratio (NHtR) in the subjects with different glucose metabolism status, the relationship between NC and insulin resistance and insulin sensitivity in different glucose metabolism groups. Results 171(62.9%) Subjects with diabetes were intervened by exercised every day. Spearman correlation analysis showed the correlation between exercise frequency and tri-glyceride triglyceride-glucose index (TyG index) (r=-0.120, P＜0.05) and NC (r=-0.168, P＜0.05) were negatively correlated. In subjects with diabetes, NC was positively correlated with triglycerides(TG) (r=-0.100, P＜0.05), homeostasis model assessment of insulin resistance(HOMA-R) (r=-0.163, P＜0.05), total cholesterol/high-density lipoprotein(TC/HDL-C)(r=-0.214, P＜0.05) and TyG index (r=-0.156, P＜0.05). Conclusions Increased frequency of exercise is associated with reduced NC, improved insulin resistance, and cardiovascular risk factors in subjects of our team with newly diagnosed diabetes. Exercise has no significant effect on insulin resistance of subjects with normal glucose tolerance and pre-diabetes.
