Birth weights and lengths were converted to weight-for-age (WAZ) and length-for-age (LAZ) z-scores using Intergrowth-21st software. Linear regression was used to compare mean z-scores adjusting for maternal and pregnancy characteristics. Among 888 infants, 49% (n = 431) were HEU and 51% (n = 457) HU. Diagnosis of growth faltering should be confirmed using a calculated z score for children with weight, weight for length, or body mass index less than the 5th percentile or if any of these For girls, the differences between the two sets of curves are 0.3 cm or 0.4 cm through the full range of z-scores. For weight-for-age, where differences between the 1977 reference and the WHO standards at 5 years were considerable, the reconstruction substantially reduced differences in the final curves.

Learn more about the Data from a Hong Kong Chinese birth cohort of ∼7500 children showed that although weight for age was close to the 50th percentile of WHO growth standards for both boys (mean z score: 0.00) and girls (0.04) at age 3 years, participants were shorter, with height z scores of −0.34 and −0.38 for boys and girls, respectively . The authors 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 Z-score scale is linear - therefore a fixed interval of Z-scores has a fixed height difference in cm, or weight difference in kg, for all children of the same age. Z-scores are sex-independent - allows evaluation of children's growth status by combining sex and age groups. Z-scores allow statistical calculations - such as means, standard In both cohorts, we observed adjusted estimates of association with adolescent FMI (Figure 1A), BMI z score, sum of SS and TR skinfolds, WC (eTables 4-7 in the Supplement), HOMA-IR value (Figure 1B), metabolic risk z score (Figure 1C), and odds of obesity (Figure 1D) during early adolescence that were generally higher with increasing age (from There are differences in the prevalence of growth indicators when using the WHO growth charts compared to the CDC growth charts. A comparison of low length-for-age, weight-for-age and weight-for-length, and high weight-for-length in US children among infants and children up to 24 months of age using the 2006 WHO growth standard charts and the 2000 CDC growth reference charts (comparing the 2.3 5 • hc: to specify the name of a numeric variable containing the head circumference information, which must be in centimeters. Users must code any missing values as no entry , in which case the head circumference-for-age z-scores are not calculated. If the survey does not have this variable for hc, users must create one and assign all its values to missing. OT3iF.
