title: [Secular trends of body adipose tissue in prepubertal children].
abstract: OBJECTIVE
  To determine whether there is a significant difference between anthropometric measurements of prepubertal children and the measurements of another sample with similar characteristics, studied fifteen years ago.
  
  
  METHODS
  We studied 859 children, 453 males and 406 females, from the age of 5.0 to 10.0 years. Weight, height, arm circumference and skinfold thicknesses in the biceps, triceps, subscapular and suprailiac were determined. Body mass index, body density, total fat and percentage fat were calculated and their values compared with those obtained 15 years ago in 1,617 children with similar characteristics. Difference between means were calculated with Student's single-sample t-test.
  
  
  RESULTS
  Weight increased in all the ages, with significant differences in males at 7, 8 and 9 years (p<0.001) and in females after the age of 6 years (p< 0.05). Height significantly increased at all ages and in both sexes, except in females at the age of 5 years. Body mass index increased only at the ages of 8 and 9 years in males (p<0.01). Skinfold thicknesses significantly increased in both sexes and at all ages (p<0.05). Body density decreased (p<0.01) and body fat increased, both in kilograms and in percentage (p<0.01).
  
  
  CONCLUSIONS
  During the 15 years studied, height and weight increased significantly. Body mass index did not increase significantly, whereas body fat (skinfold thicknesses and fat compartment) significantly increased.
