Secular Changes of Adiposity in Czech Children Aged from 3 to 6 Years: Latent Obesity in Preschool Age.

BMI, skinfold thickness, and circumferential measures were assessed in groups of normal healthy Czech boys ( = 1764) and girls ( = 1762) 3-6 years of age in the late 1950s and 1960s (sample C), in the 1990s (sample B), and in 2014-2016 (sample A). During these decades BMI has not changed significantly, and in selected groups (boys 3, 5, and 6, girls 3 and 6 years) it was most recently found to be significantly lower ( ≤ 0.05).
