Determine the relationship between skeletal muscle mass index, fat mass measured by DEXA method with subcutaneous fat layer and body mass index in students at Thai Nguyen University of Medicine and Pharmacy. Method: cross-sectional description, including 98 students divided into 2 groups: group 1 includes 49 students living in rural areas, group 2 includes 49 students living in the city to determine the relationship between SMI, fat mass and subcutaneous fat layer and BMI. Results: Male SMI was higher than female in both subjects; Men and women in the city have higher SMI than men and women in rural areas (p<0.05). Females have higher limb fat mass and total body fat than men in both areas (p<0.05). The thickness of the subcutaneous fat layer in the arms of women in both areas is higher than that of men (p < 0.05). The subcutaneous fat layer in the thighs of rural women is higher than that of men in the same area (p<0.05). Height, weight, BMI, and subcutaneous fat are weakly to very strongly related to the mass of limb, trunk, and whole body fat. Subcutaneous fat layer inversely correlates with SMI. Conclusion: - SMI in men is higher than in women. Men and women in the city have higher SMI than men and women in rural areas. The volume of limb and whole body fat and the thickness of the subcutaneous fat layer in women are higher than in men. - Weight, BMI, and subcutaneous fat have a positive correlation with the mass of limb, trunk, and whole body fat. Subcutaneous fat has a negative correlation with SMI.
