Purpose Malnutrition refers to a person's insufficient, excessive or unbalanced intake of energy or nutrients. According to WHO, in 2022, 2.5 billion adults were overweight, 890 million were obese, while 390 million were underweight. The associated health problems of obesity are more obvious and more concerned than underweight. Ultrasound has been used to measure body composition in the field of clinical nutrition,[1, 2] but the consistency of measurement varies across studies and the posture of examination is not specified. This article...
Read more Methods and materials To evaluate intra-observer and inter-observer consistency in FT measurements between two observers and to compare whether there were differences in FT for the same site across different postures, ultrasound was used to measure FT across 10 sites throughout the body in 82 participants in routine and special postures, including 45 men and 37 women. Then, body fat mass (BFM) was measured by bioelectrical impedance analysis (BlA). Additionally, fat thickness was remeasured at Site 7 (posterior upper arm) and Site 8...
Read more Results Men volunteers weighed more than women (P<0.001), with no significant difference in BMI between men and women (P=0.065), but men had lower BFM than women (P=0.005), as depicted in Table 1. [fig 1] In routine posture, FT at most sites was thicker in women than in men (P<0.001), only FT at Site 1 (intra-abdominal) was men than women (P<0.001), as depicted in Figure 2A. The intra-observer intraclass correlation coefficient (lCC) and the inter-observer lCC were 0.610 to 0.996. The FT at Site...
Read more Conclusion Ultrasound measurement of FT demonstrates good inter-observer and intra-observer consistency, with body posture being a factor influencing FT measurements. It is a better measure of local and total body fat content than BMI.
