Brei C, et al. - Researchers, for the first time, presented longitudinal ultrasound data on abdominal body fat for preschool age children. For this investigation, sonographic measurements were annually taken to evaluate the development of fat compartments in 2 to 5-year-old children. For skinfold thickness (SFT) measurements, the strongest correlations for subcutaneous fat area were consistently observed. According to the findings, preperitoneal fat area displayed rather weak to moderate associations, with greater correlation coefficients for SFT measurements vs waist circumference. A differential development of fat compartments, depending on children’s age and sex with SFT measurements as the best predictor for both fat depots was seen in the results.
