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.

Table 1: Composition of the test subjects. Abbreviations: BMI, body mass index; BF%, body fat percentage; BFM, body fat mass.
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 7 (posterior upper arm) measured in a seating posture was thicker than that in a prone posture (P<0.001), while there was no significant difference in FT at Site 8 (subscapular) between the two postures (P=0.289), as depicted in Figure 2B. There were significant differences in FT at Site 10 (posterior lower leg) among the four postures (P<0.001), the FT is the thickest in the supine posture, as depicted in Figure 2C.
Fig 2: (A) Fat thickness of men and women in the routine posture. (B) Fat thickness in the site 7 (posterior upper arm) and site 8 (sub-scapular positions). (C) Fat thickness in the site 10 (posterior lower leg). Note: ***p≤0.001 indicate there was a statistically significant difference, ns p>0.05 indicate there was not statistically significant difference.
Additionally, FT was positively correlated with skinfold thickness at Site 5 (abdominal subcutaneous fat), Site 7 (posterior upper arm) and Site 8 (subscapular)(r=0.921, 0.878, 0.882, P<0.01).
