Long-term Effect of Moderate and Vigorous Exercise on Incident Diabetes in Obese Subjects

Completed

• Conditions: Obesity, Abdominal; Type 2 Diabetes

• Registration Number: NCT05346250
• Lead Sponsor: Shanghai Zhongshan Hospital

Brief Summary

Our previous randomized controlled trial has recruited 220 subjects with central obesity and allocated the subjects to the non-exercise control, moderate exercise and vigorous exercise groups. The purpose of our previous study was to investigate the effect of moderate and vigorous exercise on improvement of fatty liver. Those subjects will be followed up for incident diabetes at 2 year and 10 year since randomization. The subjects will be invited to participate in on-site visit at 2 and 10 year. Questionaire forms will be collected and fasting plasma glucose level and HbA1c were measured. The history of diabetes and anti-diabetic medication will be recorded. The incident diabetes will be evaluated.

Detailed Description

Our previous randomized controlled trial has recruited 220 subject with central obesity and NAFLD. Those subjects were allocated into non-exercise control, moderate exercise and vigorous exercise groups, who received lifestyle education alone, moderate intensity exercise and vigorous intensity exercise, respectively. The exercise intervention lasted one year. Those three group subjects will be followed up and evaluated for incident diabetes at 2 year and 10 year since randomization. All the subjects will be invited to participate in on-site visit at 2 and 10 year. Questionaire forms will be collected and fasting plasma glucose level and HbA1c were measured. The history of diabetes and anti-diabetic medication will be recorded. The incident diabetes will be evaluated.
