Face: Buccal region: In a vertical line 1cm posterior to the modiolus (Figure 1 and 4)
Premasseteric Region: In a vertical line 1 cm anterior to the angle of the mandible (Figure 1 and 4)
Neck: Lateral neck: In a vertical line 5 cm inferior to the midline of the mandible (Figure 1) Arms: Posterior medial third of the arm in the midline (when viewed from posterior) (Figure 2 and 5)
Abdomen: Lateral Abdomen: At the level of the umbilicus in the mid-clavicular line (Figure 2 and 6)
Buttock: Gluteal region: 3 cm superior to the infra-gluteal sulcus in the middle of the buttock (Figure 2 and 7)
Thighs: Anterior thigh: Anterior lower third of the thigh, 5 cm superior to the superior border of the patella in the midline of the thigh (when viewed from anterior) (Figure 2 and 8)
Medial thigh: Medial upper third of the thigh in the midline of the thigh (when viewed from medial) (Figure 2 and 9) Posterior thigh: Posterior upper third of the thigh in the midline of the leg (when viewed from posterior) (Figure 2 and 10) All measurements were performed bilaterally. The thickness of the superficial fatty layer was measured at all given areas of interest.
Statistical Analyses
Differences between values obtained in males versus females were calculated using independent Student’s t-tests. Correlations between age, gender, and BMI and the measured distances/ thicknesses were calculated using Pearson’s correlation coefficient (rp) using bivariate correlations. To identify the influence of age, gender, or BMI, multifactorial linear regression models were calculated, and the R-squared value was used to determine the global fit of the statistical model. All analyses were performed using SPSS Statistics 23 (IBM, Armonk, NY) and results were considered significant at a probability level of ≤ 0.05.
