title: [Anthropometric measures in urban child population from 6 to 12 years from the northwest of México].
abstract: BACKGROUND
  The degree of overweight-obesity varies according to the conditions of each population and depending on geographical area, race or ethnicity, socioeconomic status, and susceptibility of each individual. The aim of this study was to determine anthropometric measures in urban child population from 6 to 12 years of Ciudad Obregón, Sonora.
  
  
  METHODS
  We studied 684 schoolchildren from 6 to 12 years of age, of both genders in the urban area of Ciudad Obregón, Sonora. We measured weight, height, arm circumference (AC), waist, and body mass index (BMI). We used descriptive statistics (frequencies, percentages), and to compare the growth charts of this study vs. the reference standards (CDC and Ramos-Galván), we employed statistical inference (Student t test).
  
  
  RESULTS
  On average, weight, height, AC, BMI for age by gender were higher than the reference standards at all ages. Seventy-four boys (22 %) and 51 girls (14.5 %) were above 95th percentile. With regards to size, 42 children (12.6 %) were below the 5th percentile and 37 (10.5 %) above the 95th percentile.
  
  
  CONCLUSIONS
  Schoolchildren in the southern zone of Sonora showed a higher anthropometric pattern than the reference standards.
