Brief Summary
This study tests whether using a health app (Huawei Health) and a smart body fat scale can help overweight patients with schizophrenia or bipolar disorder lose weight and stay engaged in their health. What We're Testing:
- 1.Patients who use the app and scale for 4 months (Group 1) will lose more weight than those who use them for 2 months (Group 2).
- 2.Patients who track their weight, diet, and exercise regularly (≥3 times/week) will lose more weight than those who don't.
- 3.Seeing weight loss results may motivate patients to keep using the app and scale.

Outcome Measures
Primary Outcomes (2)
Percent weight loss
Proportion of body weight lost, assessed via smart scale synced with app. Factors distinguish those who do/don't lose weight is detected by using machine learning.
At the end of Months 1, 2, 3, and 6
Adherence to self-monitoring
Number of days per week participants complete self-weighing, dietary logging and follow up visits.
At the end of Months 1, 2, 3, and 6
Secondary Outcomes (4)
Longitudinal adherence to self-monitoringcompliance to app + scale protocol and the participants who have bad compliance is compared by percent weight loss.
At the end of Months 1, 2, 3, and 6
Weight loss by adherence level
At the end of Months 1, 2, 3, and 6
Association between adherence and weight loss
At the end of Months 1, 2, 3, and 6
Prediction of future adherence by prior weight loss
At the end of Months 1, 2, 3, and 6
Study Arms (2)
Batch 1 (Intervention from Month 3)
EXPERIMENTAL3 clinical units (clusters) receiving the combined digital and multidisciplinary intervention starting at Month 3. Each unit includes approximately 34 patients (total n=102) with schizophrenia or bipolar disorder.
Batch 2 (Intervention from Month 5)
EXPERIMENTAL3 clinical units (clusters) receiving the same intervention starting at Month 5. Each unit includes approximately 34 patients (total n=102) with schizophrenia or bipolar disorder.
Interventions
Participants receive a digital-behavioral intervention via Huawei Health App and smart scale: 1. Weekly weigh-ins (auto-synced) 2. Dietary logging (≥3x/week) with calorie-deficit targets 3. Biweekly exercise plans (150-300 min/week) 4. Weekly motivational messages Implementation: Staggered rollout: Batch 1 (Month 3-6), Batch 2 (Month 5-6). Includes 2-week training. Effectiveness monitored via app metrics and adherence. Routine care maintained.
Eligibility Criteria
You may qualify if:
- Age 18-60 years old, no gender restriction.
- According to ICD-10 to diagnose bipolar disorder or schizophrenia, the researcher judges that the patient is currently in remission, or the condition is stable and can cooperate with the research.
- Currently using at least one antipsychotic or mood stabilizer (e.g. lithium, magnesium valproate, sodium valproate, lamotrigine).
- Currently overweight or obese (body mass index ≥ 24kg/m2) and willing to use health app and smart scales to lose weight.
- The education level of primary school or above, able to understand the content of the scale, and be able to use smart phone proficiently.
- Understand and voluntarily participate in this study, and sign the informed consent form.
You may not qualify if:
- Plan to lose weight by other methods during the study period (such as dieting, inducing vomiting, taking diet pills, surgery).
- Self-reported weight loss ≥ 7% in the past 6 months.
- Weight over 150 kg.
- Other secondary obesity (such as hypothyroidism, Cushing's syndrome, hypothalamic obesity, etc.).
- Currently pregnant, lactating, \< 6 months postpartum or planning to become pregnant during the study period.
- Self-reported cardiac discomfort or chest pain during activity or at rest.
- There is a serious medical condition, and the researchers believe that there may be safety risks when participating in sports.
- Be unable to walk 30 minutes without stopping.
- There are problems that may affect compliance with the protocol (eg, end-stage disease, planning to move travel to the field, history of substance abuse, other uncontrolled or untreated medical conditions);
- Any other conditions deemed inappropriate by the investigator.
- Participants include approximately 50% with schizophrenia and 50% with bipolar disorder, distributed across all clusters.
