About

This RCT study will evaluate the effect of a lifestyle intervention on overweight or obese patients with type 2 diabetes mellitus. The primary hypothesis is that the mHealth-based intensive lifestyle intervention is sufficient to achieve weight loss and maintain glycated hemoglobin control.

Full description

Diabetes mellitus is a chronic systemic metabolic disease caused by the long-term interaction of genetic factors and environmental factors. It is characterized by an increase in plasma glucose levels and is mainly due to metabolic disorders in glucose, fat, and protein caused by insufficient insulin secretion and/or dysfunction in the body, which affects normal physiological activities. As of 2019, 463 million people are suffering from diabetes in the world, of which 90% to 95% have type 2 diabetes mellitus (T2DM), with an average of 1 patient in every 11 adults (aged 20-79). The number of patients with T2DM will jump to 700 million by 2045. There is a close relationship between T2DM and overweight and obesity. The prevalence of diabetes in overweight and obese people in China was 12.8% and 18.5%, respectively. Among T2DM patients, the proportions of overweight and obesity were 41% and 24.3%, respectively.The two kinds of diseases share a common key pathophysiological mechanism, which will have a devastating long-term impact on patients' health and bring serious disease and economic burden to the family. Given the various harms, it is urgent to carry out relevant intervention research and formulate effective intervention strategies. With the development of artificial intelligence technology, the combination of mHealth and multidisciplinary lifestyle intervention may become an efficient and easy-to-popularize management mode for the prevention and treatment of T2DM with obesity.

Given the relative lack of high-quality interventions for T2DM overweight/obesity, the investigators designed a randomized controlled trial to assess the effectiveness of a multicomponent intervention in Ningbo First Hospital. This study plans to adopt the online and offline combination method based on mHealth technology to carry out lifestyle intervention aimed at formulating a set of feasible and effective intervention strategies.

The study aims to identify: 1) whether the mHealth-based intensive lifestyle intervention will be effective for weight and glycated hemoglobin management to reverse or slow down the disease process among T2DM patients with overweight/obesity; 2) whether the intervention will be beneficial for improving biochemical indicators, body composition indicators, and exercise capacity among T2DM patients with overweight/obesity.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

120 participants in 2 patient groups

lifestyle intervention

Experimental group

Description:

1. Weight monitoring: Participants are required to record the weighting data in the WeChat official account at least once a week to lose 5% or more of their initial body weight in 3 months. 2. Goals record: At baseline, the participants need to complete a behavioral goals questionnaire. All these behaviors are then ranked for each participant based on an algorithm that determines the participants'self-reported necessity, self-efficacy, and estimated caloric deficit from performing that behavior. The top six goals are assigned to each participant with two for every 4-week cycle. 3. Exercise: The form is the combination of aerobic exercise (3d/w) and resistance exercise(2d/w). Each participant will be equipped with a Huami watch as a means of monitoring. 4. Health education: Participants are provided with T2DM-related knowledge. They can also contact the endocrinologist online and offline.

Treatment:

Behavioral: lifestyle intervention

usual-care control

No Intervention group

Description:

Participants assigned to the control group will receive routine medical care and diabetes education, and be treated with hypoglycemic drugs under the guidance of endocrinologists according to the patient's condition and clinical treatment standards throughout their participation in the trial. After finishing the study, they will be offered healthy management as the participants in the multi-component lifestyle intervention group.
