Find the charts, tables and instructions for estimating the weight-for-age z-scores and percentiles for children from birth to 5 years old. Download the z-scores and percentiles in PDF or Excel formats for girls and boys by age groups and time periods. To detect relevant confounders in a multivariate analysis, we calculated height for age z-scores (i.e. length or height), weight for age z-scores and BMI z-scores 17. The z-scores were calculated BAZ BMI-for-age z-score BMI Body mass index (weight in kg divided by height in metres squared) DoB Date of birth DoV Date of visit FAO Food and Agriculture Organization of the United Nations HAP Length or height-for-age percentile HAZ Length or height-for-age z-score IA Individual assessment module The objectives of this study were (1) to apply the weight gain z-score charts in two different U.S. populations as an assessment of generalisability and (2) to determine whether race/ethnicity modifies the weight gain range associated with minimal risk of preterm birth. The study sample included over 4 million live, singleton births in Simplified field tables BMI-for-age BOYS 5 to 19 years (z-scores) Year: Month Months -3 SD -2 SD -1 SD Median 1 SD 2 SD 3 SD 5: 1 61 12.1 13.0 14.1 15.3 16.6 18.3 20.2 Notes. This calculator uses measured recumbent length for infants and toddlers from birth through 24 months of age.; It is not valid for standing height. At the extremes (>97 th percentile or <3 rd percentile), small differences in percentiles represent clinically important differences. At these extremes, the Z-score is a more precise reflection of how far the measurement deviates from the Zn0gE9.
