Different effects of living high - training low and living low - training low on insulin sensitivity and cytokine secretion in obese children

摘要

Objective: To explore the different effects of living high - training low and living low - training low on insulin sensitivity and cytokine secretion in obese children. Methods: A total of 218 obese children who were treated in this hospital between September 2015 and February 2018 were selected and randomly divided into the living high - training low group (n=109) and living low - training low group (n=109). Living high - training low group received living high- training low intervention, living low - training low group received living low - training low intervention, and the intervention of both groups lasted for 4 weeks. The differences in serum levels of insulin sensitivity-related indexes as well as the contents of appetite-related hormones and adipocytokines were compared between the two groups of children before intervention and after 4 weeks of intervention. Results: Before intervention, the levels of insulin sensitivity-related indexes as well as the contents of appetite-related hormones and adipocytokines in serum were not significantly different between the two groups of obese children. After 4 weeks of intervention, serum insulin sensitivity-related indexes ISI, FPIR and GDR levels of living high-training low group were higher than those of living low - training low group; appetite-related hormones CCK and PYY3-36 contents were higher than those of living low - training low group whereas Ghrelin content was lower than that of living low - training low group;adipocytokines omentin-1 and APN contents were higher than those of living low - training low group whereas chemerin and LEP contents were lower than those of living low - training low group. Conclusion: Compared with traditional living low - training low intervention, living high - training low intervention is more effective in improving the insulin sensitivity and balance the secretion of appetite-related hormones and adipocytokines in obese children.
