Overweight or Obesity
Conditions
Brief summary
This study applied digital technology to a comprehensive lifestyle intervention strategy to design a digital behavioural intervention programme suitable for weight reduction in overweight obese infertile patients in China, and assessed its intervention effect through a randomised controlled trial.The main questions it aims to answer are: 1\) Design and implement a digital behavioural weight loss intervention programme; 2) Evaluate the impact of digital behavioural interventions on weight loss outcomes and health outcomes. Participants will be randomly assigned to a control group and an intervention group. The control group will receive only routine health education and the intervention group will receive an 8-week digital behavioural intervention. At the end of the intervention, the follow-up period will be one year for reproductive outcomes.
Interventions
The intervention team provides lifestyle guidance to the subjects according to the behavioural intervention programme, and the subjects record information on diet, exercise and weight on the platform on a daily basis. Subjects are required to learn relevant health education knowledge on the platform by themselves, and they can also exchange experience in the group and receive motivational counselling from the instructors.
