Study Overview
Brief Summary
In the past three decades, obesity has emerged insurmountably, not only in affluent nations but also in many low- and middle-income countries worldwide. It has been linked to various non-communicable diseases, including hypertension, coronary heart disease, diabetes mellitus, dyslipidemia, stroke, colorectal cancer, and many other chronic conditions, such as musculoskeletal disorders, putting tremendous pressure on healthcare systems and the socio-economy. The Asia and Pacific region harbors the highest absolute number of people with overweight and obese, amounting to approximately 1 billion. In Southeast Asia, the prevalence of overweight and obesity increased by almost 40% between 1990 and 2013. Although Vietnam has the lowest percentage of obese adults in the region (about 3.6%), we experienced a 38% increase in the number of obese people between 2010-2014, much higher than that in the University Kingdom and the United States (10% and 8% correspondingly). However, the problem is underestimated by not only healthcare professionals but also patients with obesity. These alarms underscore the necessity of implementing a comprehensive assessment and more focused and practical strategies for addressing obesity in Vietnam, where data has been limited. Therefore, our research has two arms: (1) characterization of patients with obesity to identify those at the highest risks for obesity complications, and (2) understating the attitudes and perceptions of people living with obesity to gain insights into the psychological factors associated with obesity. This research will be a foundation for further research on obesity in Vietnam and Southeast Asia.
Detailed Description
All Vietnamese, aged 18-65, diagnosed with obesity defined by BMI ≥ 25 kg/m2 as per Asia-Pacific Guidelines for Obesity, present at University Medical Center Ho Chi Minh City and My Duc General Hospital outpatient clinics, will be enrolled to the study. The patients will have:
- Standard anthropometric data will be done, using a professional medical HM200P Portable Height Stadiometer and a standardised ISO (International Organization for Standardization) 9001:2015 weight scale, by professional and experienced physicians according to standard study protocol: Weight, height, waist and hip circumference, waist to hip ratio, BMI calculated, followed by World Health Organization guidelines for Asian people.
- Blood pressure measure.
- Fat mass measured by the Tanita MC-780 MA (Serial: 17050004).
- Blood tests: fasting plasma glucose, cholesterol, HDL-C, LDL-C, and triglyceride.
- Mood disorder screening by answering a Patient Health Questionnaire-9.

Outcomes
Primary Outcomes
Hip circumference
Time Frame: At baseline
To be measured around the widest portion of the buttocks.
Blood pressure
Time Frame: At baseline
Systolic and diastolic pressure measurements will be taken using a standardized sphygmomanometer.
Height measurement
Time Frame: At baseline
Using a professional medical HM200P Portable Height Stadiometer
Total cholesterol
Time Frame: At baseline
Total cholesterol (mmol/L) concentrations in serum
Weight measurement
Time Frame: At baseline
Using standardized weight scale (ISO 9001:2015)
HDL cholesterol
Time Frame: At baseline
HDL cholesterol (mmol/L) concentrations in serum
LDL cholesterol
Time Frame: At baseline
LDL cholesterol (mmol/L) concentrations in serum
Risk of depression score
Time Frame: At baseline
Risk of depression will be assessed using PHQ-9 (Patient Health Questionnaire-9). It is scored on a 27-point scale. Those with a PHQ-9 score less than five is considered at no risk of depression, and those with a PHQ-9 score equal to or more than 5 are at risk of depression.
Waist circumference
Time Frame: At baseline
To be measured at the approximate midpoint between the lower margin of the last palpable rib and the top of the iliac crest
Body Mass Index
Time Frame: At baseline
Weight in kilograms divided by height in meters squared
Fasting plasma glucose
Time Frame: At baseline
Fasting plasma glucose (mmol/L) concentrations in serum
Triglycerides
Time Frame: At baseline
Triglycerides (mmol/L) concentrations in serum
Body composition change
Time Frame: At baseline
Body fat mass (% BFM), body fat percentage (%BF), muscle mass, skeletal muscle mass (% SMM) and visceral fat rating will be evaluated to assess body composition change. Measurements will be assessed using a Electrical bioimpedance (BIA)
Secondary Outcomes
- The relationship between the severity of obesity to body composition(At baseline)
- The relationship between the severity of obesity to anthropometric parameters(At baseline)
- The relationship between the severity of obesity to biochemical parameters(At baseline)
- The relationship between the severity of obesity to risk of depression(At baseline)
