简要总结
This randomized control trial aims to evaluate the effectiveness of a culturally and linguistically adapted nutrition education and physical exercise program on lifestyle (diet and exercise), metabolic parameters, and fat content and distribution of people of Pakistani origin with obesity residing in the North Metropolitan health area of Barcelona. The betterment of the mentioned parameters is expected to be greater in individuals from the intervention group who will receive a total of 12 sessions of nutrition education and physical exercise compared to the control group who will participate in only 4 sessions.
详细描述
This study aims to assess the impact of a culturally and linguistically adapted nutrition education and physical exercise program on the acquisition of heart-healthy habits (diet and exercise), various metabolic parameters (including glycemic and lipid markers), and the content and distribution of ectopic fat in individuals of Pakistani origin with obesity residing in the North Metropolitan Health Area of Barcelona.
A 6-week intensive randomized controlled trial (RCT) will be implemented with a total of 60 participants. Baseline data will be collected using both quantitative and qualitative methods by a multidisciplinary team of nutrition and nursing professionals. Quantitative methods will be employed to gather data on sociodemographic characteristics, health status, quality of life, clinical variables, body composition, eating habits, nutrition knowledge and skills, and physical activity. Qualitative methods will be used to adapt the intervention to the cultural and practical needs of participants and to explore variables such as eating habits and nutrition-related skills in greater depth.
Study data will be collected and managed using REDCap (Research Electronic Data Capture) tools hosted at Germans Trias i Pujol University Hospital.
Following baseline assessments, participants will be randomized into intervention (n=30) and control (n=30) groups using simple random assignment via a table of random numbers. The randomization sequence will be concealed in sealed, opaque envelopes labeled with participant codes.
The intervention group will receive one weekly theoretical-practical nutrition education session conducted in Urdu and one Nordic walking-based physical activity session per week, over a period of 6 weeks (totaling 6 nutrition sessions and 6 physical activity sessions). Nutrition education sessions will be conducted in the therapeutic kitchen of Germans Trias i Pujol University Hospital. Physical activity sessions will take place in public green spaces near participants' residential areas.

Control
Usual care
干预措施: Usual Care Group (Behavioral)
结局指标
主要结局
Gamma-glutamyl transferase (GGT)(UI/L)
时间窗: Baseline, 3 months, 6 months
GGT will be measured using enzymatic colorimetric methods.
Total cholesterol (mg/dL)
时间窗: Baseline, 3 months, 6 months
Total cholesterol will be measured using enzymatic colorimetric methods.
LDL cholesterol (mg/dL)
时间窗: Baseline, 3 months, 6 months
LDL-C will be measured directly via homogenous enzymatic assay.
HDL cholesterol (mg/dL)
时间窗: Baseline, 3 months, 6 months
HDL-C will be measured directly via homogenous enzymatic assay.
Adherence to Mediterranean Diet using modified MEDAS questionnaire
时间窗: Baseline, 3 months, 6 months
Adherence to the Mediterranean Diet will be assessed using a modified version of the 14-item Mediterranean Diet Adherence Screener (MEDAS), excluding the alcohol intake item (13 items total). Scores range from 0 to 13, with higher scores indicating better adherence. A score \< 9 indicates low adherence; ≥ 9 indicates good adherence.. Unit of measure: score 0-13
Nutrient intake measured by 24-hour Dietary Recall
时间窗: Baseline, 3 months, 6 months
Nutrient and food group intake will be assessed using a structured 24-hour Dietary Recall (24HR), administered by trained staff. Data will be analyzed using nutritional analysis software to estimate daily intake. Unit of measure: grams, Kcal
Fat mass and total body mass measured by bioimpedance analysis
时间窗: Baseline, 3 months and 6 months
Body fat mass and total body mass will be quantified using bioimpedanciometry
Thickness of superficial and pre-peritoneal fat (mm) measured by ultrasound of the rectus abdominis
时间窗: Baseline, 3 months, and 6 months
Subcutaneous and pre-peritoneal fat thickness will be assessed using ultrasound imaging of the rectus abdominis muscle.
Quadriceps muscle thickness (mm) measured by ultrasound
时间窗: Baseline, 3 months, and 6 months
Muscle mass will be evaluated through ultrasound measurements of the quadriceps muscl
Body Mass Index (BMI) in kg/m²
时间窗: Baseline, 3 months, and 6 months
BMI will be calculated as weight in kilograms divided by height in meters squared (BMI = kg/m²). Weight will be measured using a calibrated digital scale, and height will be measured with a portable stadiometer.
Waist circumference (cm)
时间窗: Baseline, 3 months, and 6 months
Waist circumference will be measured at the midpoint between the lowest rib and the iliac crest using non-stretchable tape, recorded to the nearest 0.1 cm with the participant standing.
Physical exercise
时间窗: Baseline, 3 months and 6 months
The information related to the physical exercise will be gathered through the validated Urdu version of the International Physical Activity Questionnaire (IPAQ). Results will be reported as a continuous variable (MET minutes a week). Furthermore, participants from both the control and the intervention group will be provided with a smartwatch that will register their daily physical activity. The results will be presented in total minutes of intense and moderate physical activity per week.
Health-related quality of life
时间窗: Baseline, 3 months and 6 months
Perceived physical and mental health will be assessed using the 12-Item Short Form Survey (SF-12).

The total score range is 12-47 (higher scores mean a worse outcome).
