title: [Decreased anthropometric indicators of adiposity in school children as an indicator of the nutritional transition in Mexico].
abstract: BACKGROUND
  The aim of this paper was to estimate the adiposity trend in children from a public elementary school in Guadalajara, Mexico, between 2007 and 2011.
  
  
  METHODS
  Comparative study of two samples taken transversely in 1432 schoolchildren aged 6-12 years. Z-score of BMI and anthropometric indicators of arm adiposity (triceps skinfold, fat area and arm fat index) were calculated. Reference standards of the 2007-WHO and Frisancho were used. Analysis: Chi-square and Student t test.
  
  
  RESULTS
  Adiposity decreased significantly in children with normal weight (arm fat area Z-score -0.3 SD) overweight and obesity (arm fat area and index -0.4 and -0.3 z-scores respectively). An increase in the prevalence of subjects with normal weight and thinness and a decrease of overweight (4.6, -2.0 and -2.9 percentage points respectively) was observed. Obesity prevalence remained unchanged.
  
  
  CONCLUSIONS
  Decrease of adiposity in overweight and obese children, reduction in the prevalence of thinness and overweight and the increase in the proportion of subjects with normal weight was observed during the study period. These data probably reflect the nutritional transition in Mexico.
