[Growth and nutritional status in a probabilistic sample of schoolchildren from Rio de Janeiro, 1999].

Growth and nutritional status were assessed in a probabilistic sample of public schoolchildren (1,705 girls and 1,682 boys) in the city of Rio de Janeiro in 1999. Nutritional status of the under-10-year group was assessed by z < -2 (undernutrition) for body mass for height and height for age and by z > +2 for body mass for height (overweight). For children over 10, the 5th and 85th percentiles of body mass index for age were used to assess underweight and overweight, respectively.
