  7. ZSTATAGE [XLS - 188 KB] ZSTATAGE [CSV - 98 KB]    
    Stature-for-age charts, 2 to 20 years, selected stature z-scores in centimeters, by sex and age
  8. ZBMIAGE [XLS - 188 KB] ZBMIAGE [CSV - 98 KB]    
    BMI-for-age charts, 2 to 20 years, selected BMI (kilograms/meters squared) z-scores, by sex and age

These files contain the z-scores values for the z-scores of –2, -1.5, -1, -0.5, 0, 0.5, 1, 1.5, and 2 by sex (1=male; 2=female) and half month of age. For example, 1.5 months represents 1.25-1.75 months. The only exception is birth, which represents the point at birth.
