Brief summary
The research employs a quasi-experimental design, aiming to enroll 24 hospitalized patients with schizophrenia from 2hospitals in the central region, guided by G Power calculations. Participants will be carefully matched based on gender, age (within 5 years), and the same hospital. They will be divided into two groups using a single-masked randomized allocation method. The experimental group (psyllium husk group) will consume 10 grams of psyllium husk daily, split into two doses, taken about an hour before meals. The control group will receive standard treatment. The intervention will last for 12 weeks. Inclusion criteria involve a schizophrenia diagnosis as per DSM-V criteria, age between 20 and 65 years, and a body mass index (BMI) of 24 kg/m² or higher, or meeting more than three indicators of metabolic syndrome. Exclusion criteria include medications for glucose, blood pressure, or lipid levels reduction, significant comorbidities like cardiovascular diseases or cancer, a history of neurogenic bowel obstruction or post-weight loss surgery, and patients with severe psychiatric symptoms impeding cooperation. Each patient will undergo measurements for weight, waist circumference, body mass index, and blood biochemical analysis, encompassing fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and glycated hemoglobin (HbA1c) before the intervention and after 12 weeks.
Detailed description
The study adopts a quasi-experimental research design and plans to include 24 hospitalized patients with schizophrenia from 2 hospitals in the central region, based on G Power calculations. This study will be matched based on gender, age (within 10 years), and the same hospital.The participants will be divided into two groups using a single-masked randomized allocation method. The experimental group (psyllium husk group) will consume 10 grams of psyllium husk daily, divided into two doses, and taken approximately one hour before meals. The control group will receive standard treatment, and the intervention will last for 12 weeks. Inclusion criteria are: 1. Diagnosis of schizophrenia based on DSM-V criteria; 2. Age between 20 and 65 years old; 3. Body mass index (BMI) of 24 kg/m² or higher or those who meet more than three indicators of metabolic syndrome. Exclusion criteria are medications for lowering blood glucose, blood pressure, or lipid levels, significant comorbidities such as cardiovascular diseases or cancer, history of neurogenic bowel obstruction or post-weight loss surgery, and patients with prominent psychiatric symptoms who cannot cooperate. Each patient will undergo measurements of weight, waist circumference, body mass index, and blood biochemical analysis data, including fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and glycated hemoglobin (HbA1c) before the intervention and after 12 weeks

Intervention model description
. This study will be matched based on gender, age (within 10 years), and the same hospital.The participants will be divided into two groups using a single-masked randomized allocation method. The experimental group (psyllium husk group) will consume 10 grams of psyllium husk daily, divided into two doses, and taken approximately one hour before meals. The control group will receive standard treatment, and the intervention will last for 12 weeks. Inclusion criteria are: 1. Diagnosis of schizophrenia based on DSM-V criteria; 2. Age between 20 and 65 years old; 3. Body mass index (BMI) of 24 kg/m² or higher or those who meet more than three indicators of metabolic syndrome. Exclusion criteria are medications for lowering blood glucose, blood pressure, or lipid levels, significant comorbidities such as cardiovascular diseases or cancer, history of neurogenic bowel obstruction or post-weight loss surgery, and patients with prominent psychiatric symptoms who cannot cooperate.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Body Weight in Kilograms | At baseline (week 0) and at weeks 6 and 12 of the study. | Measure body weight in the morning after waking up, with participants wearing light clothing and no shoes. |
| Waist Circumference in cm | At baseline (week 0) and at weeks 6 and 12 of the study. | Waist circumference will be measured to evaluate the impact of psyllium husk intervention on abdominal fat distribution in patients with schizophrenia. Measurements will be conducted using a flexible, non-stretchable measuring tape, positioned horizontally around the abdomen at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest. Participants will stand upright, with feet close together, arms at their sides, and abdomen relaxed during the measurement. The values will be recorded in centimeters (cm). The experimental group will consume 10 grams of psyllium husk daily, while the control group will receive standard treatment. Changes in waist circumference will be analyzed within and between groups. |
| Body Mass Index (BMI) in (kg/m²) | At baseline (week 0) and at weeks 6 and 12 of the study. | Body mass index (BMI) will be calculated to evaluate the impact of psyllium husk intervention on overall body composition in patients with schizophrenia. BMI is expressed in kilograms per square meter (kg/m²) and will be calculated using the formula: weight (kg) divided by height squared (m²). Weight will be measured with a calibrated digital scale, ensuring participants wear light clothing and no shoes. Height will be measured using a wall-mounted stadiometer, with participants standing barefoot, heels together, arms at their sides, and head positioned in the Frankfurt horizontal plane. These measurements will be used to calculate BMI, which will be recorded and analyzed for changes within and between groups. |
