Brief Summary

The national epidemiological survey showed that the prevalence rate of pre-diabetes was up to 35.7% in China. Previous study indicated that lifestyle intervention in people with impaired glucose tolerance could delay the onset of type 2 diabetes. However, patients with pre-diabetes do not pay enough attention to their glucose metabolism, and most of them rarely monitor their blood glucose. With the increasing use of smartphones, mobile applications (APPs) can be applied in the education and management of chronic diseases, including diabetes. Thus, the investigators will conduct a multi-centered, two-armed, open-labeled, randomized controlled trial to evaluate whether the behavioral intervention by a mobile APP can prevent the occurrence of diabetes in people with impaired glucose tolerance. The investigators hypothesize that behavioral intervention in pre-diabetes with using a mobile APP that incorporates nutrition, exercise and psychological support from trained professional doctors will:

1. 1.Reduce the risk of the onset of diabetes in people with impaired glucose tolerance.
2. 2.Increase the reversal rate of becoming normal glucose tolerance and reduce the levels of glycosylated hemoglobin in pre-diabetes.

Outcome Measures

Primary Outcomes (1)

• The risk of diabetes mellitus (DM) in patients with impaired glucose tolerance

  DM will be diagnosed by a 75g OGTT according to the World Health Organization criteria as fasting plasma glucose level 7.0 mmol/L or more, or 2-hour value 11.1 mmol/L or more. Investigators will compare the diabetes risk in the two groups to evaluate whether behavioral intervention with a mobile APP can reduce the risk of the onset of diabetes in people with impaired glucose tolerance.

Secondary Outcomes (2)

• Reversal rate of becoming normal glucose tolerance in pre-diabetes

  2 years

• Changes in glycosylated hemoglobin levels.

Behavioral intervention

EXPERIMENTAL

Participants randomized to the behavioral intervention group will be provided with a mobile APP which incorporates behavioral support including health knowledge education, mental health counseling, diet advice, exercise guidance and weight management. Meanwhile, the behavioral support will be modified by endocrinologists, dieticians, sports medicine professionals and psychologists individually based on the feedback of their performance recorded in the APP. Every three months, participants in the intervention group will be back to their research centers and be collected with information including HbA1c levels, blood pressure, heart rate tests and adverse events. Investigators conduct face-to-face health education, lifestyle guidance, mobile APP software inspection. Every one year, 75g OGTT (0min,60min, 120min points of blood glucose and insulin levels), liver and kidney function, blood lipids, glycosylated hemoglobin, urine routine and electrocardiogram will be evaluated.

Behavioral: Lifestyle intervention with APP

Control group

NO INTERVENTION

Participants randomized to the control group have regular care in their local hospitals. Every three months, participants in the intervention group will be back to their research centers and be collected with information including HbA1c levels, blood pressure, heart rate tests and adverse events. Every one year, 75g OGTT (0min,60min, 120min points of blood glucose and insulin levels), liver and kidney function, blood lipids, glycosylated hemoglobin, urine routine and electrocardiogram will be evaluated.

Interventions

Lifestyle intervention with APP BEHAVIORAL

The lifestyle intervention will be launched by an APP installed in participants' private mobile phones, including health knowledge education, mental health counseling, smart diet advice, intelligent exercise guidance, and target weight management. Nutrition recommendation is conducted according to the Chinese Dietary Guide, Chinese and International Guidelines of Gestation Diabetes Management. Exercise guidance is given based on the Guidelines for National Fitness of China, Chinese and International Guidelines of Gestation Diabetes Management. Psychological support is given by sending education articles on mental health. Participants are encouraged to update data about their diet, exercise and body weight through the APP. The face to face education class will be conducted by an obstetrician, an endocrinologist and a nutritionist together to modify the behavioral supports individually based on the feedback of their characteristics and performance recorded in the APP.
