Objective To evaluate the misclassification resulting from the use of body mass index (BMI) cut-points defined by rounded percentiles instead of Z-scores in early childhood. Using data from the TARGet Kids primary care network we conducted a cross-sectional study among 5836 children < 6 years of age. The World Health Organization growth standards were used to calculate BMI-for-age Z-scores Additionally, it provides a command routine in Stata, which processes the z-scores of the anthropometric indices height-for-age and weight-for-height and presents the respective prevalence of the nutritional conditions. Data from two household surveys were used to demonstrate the application of AWC, which were conducted in 1992 (n = 1229) and WHO Child Growth Standards Weight-for-age BOYS 6 months to 2 years (z-scores) Months Age (completed months and years) Weight (kg) 6 7 8 9 10 11 1 2 3 4 5 6 7 8 9 10 11 Simplified field tables Weight-for-age GIRLS Birth to 13 weeks (z-scores) Weeks -3 SD -2 SD -1 SD Median 1 SD 2 SD 3 SD 0 2.0 2.4 2.8 3.2 3.7 4.2 4.8 .
