Short-term effects of lifestyle intervention in the reversion to normoglycemia in people with prediabetes

Aims: To evaluate the short-term effect of lifestyle intervention in people with prediabetes. Methods: A stratified multistage sampling method was used in the recruitment of residents of the Jiangsu Province, China in 2017, who had no previous diagnosis of diabetes. Physical examination and laboratory tests were performed, and questionnaires were completed. Those with a prediabetes diagnosis at baseline were included in the cohort and participants were randomized to the intervention group or the control group. The intervention group received a lifestyle intervention strategy, which included exercise, diet and peer educations. The control group received general health education. Participants were followed up in 2018. Results: A total of 2005 individuals were included in the analysis. At follow-up, there were 516 (36.7%) individuals in the intervention group and 207 (34.5%) individuals in the control group with normal blood glucose levels. The decline in waist circumference and fasting plasma glucose levels was significantly higher in the intervention group than in the control group. This was still observed after adjusting for variables (odds ratio 1.32, P = 0.02). Females or younger individuals who had lower body mass index and plasma glucose levels at baseline were more likely to reverse to normoglycemia at follow-up. Conclusions: Compared with a strategy of general health education, a lifestyle intervention strategy could reverse glucose levels to normoglycemia in individuals with prediabetes.
