“…[ 3 4 ] It is worth indicating that we have recently completed the analysis of national data to establish not only the percentile but also Z score-based growth reference for Saudi children and adolescents. [ 5 ] Second, we note that the colleague agrees with our recommendation on the need for prospective study on this subject. Third, it is well-known that genetic influences on growth are always possible not only in Crohn's disease but also in general.…”

“…The Z-score indicates how many standard deviations any value is from the mean. 25 In contrast with a previous research done on 2002, also based on local data, presented the anthropometric parameters using the percentile method 18, our study is the rst tool in Egypt to use LMS and Z score growth parameters method that provide more accuracy than percentiles that were used before. When compared with this study in Egypt, the previous study was done only on one governorate of Egypt and was based on percentile, but our report was done in many governorates that were representative to Egypt and based on LMS and Z score method that is more accurate.…”

Abstract Background:Growth charts are an important method for evaluating a child's health, growth and nutritional status.Objective:To establish Lambda – Mu- Sigma (LMS) and Z score references for assessment of growth and nutritional status in Egyptian school children and adolescents.Methods:A total of 34,822 Egyptian school children and adolescents from 5 to 19 years were enrolled in a cross sectional randomized study from December 2017 to November 2019 to create LMS and Z score references for weight, height and body mass index (BMI) corresponding to ages. They were selected from different districts in Egypt. Apparent Healthy children with good nutritional history and not suffering from any chronic diseases were included in the study.Results:Egyptian children of both sexes (54.3% boys and 45.7 % girls) from 5 to 19 years old were studied. Then LMS and Z scores for weight for age, height for age, BMI for age of both sexes were represented in detailed tables and graphs. There was no statistically significant difference between the Egyptian Z score charts and the reference values of WHO for weight, height and BMI corresponding to age (P>0.05).Conclusion: This is the first national reference for growth and nutritional assessment using LMS and Z score charts in Egyptian school children and adolescents, this tool is essential for healthcare and research.Key words: Adolescent - Egyptian Z score -Growth parameters- Nutritional status-School children

“…z-scores correspond exactly to the percentiles, e.g., zscores of − 1.881, − 1.645, − 1.282, − 0.674, 0, 0.674, 1.036, 1.282, 1.645, and 1.881 correspond to the 3rd, 5th, 10th, 25th, 50th, 75th, 85th, 90th, 95th, and 97 th percentiles, respectively [19]. The goodness of fit of all models was assessed using the worm plot and Q test [6,18,19]. We have estimated the 3rd, 5th, 15th, 50th, 85th, 90th, 95th, and 97th percentiles for height-for-age, weight-forage, and BMI-for-age.…”

“…We supposed that data could be corrected for skewness by using an appropriate power transformation (L), and the distribution was summarized by the median (M) and generalized coefficient of variation (S). The LMS method is used to model the data, smooth the parameters (L, M, and S), and then estimate the smoothed percentiles from the model parameters [6,18,19]. The model parameters were estimated based on the method of maximum penalized likelihood.…”

Background: There are no national reference charts in Iran for children aged under five. This study aimed to develop representative growth reference charts of height, weight, and BMI for children aged 2-5 years in Isfahan, Iran, and to compare them with the WHO reference curves. Results: This population-based study has a combination of longitudinal and cross-sectional design. It included 1325 and 761 healthy children, who were born between 2002 and 2015 in Isfahan, central Iran, in longitudinal and crosssectional phases. Expert health care providers measured the height and weight of children in health centers. The lambda-mu-sigma method was used to construct the age-and sex-specific growth charts of anthropometric measures. The study sample comprised 1029 boys and 1057 girls. The centiles of height, weight, and BMI of boys were higher than that of girls in all age groups. The weight patterns of studied children were close to those of the WHO references in the lower percentiles. However, our study children, especially girls, were lighter compared with WHO standards based on the middle and upper percentiles of the weight distribution. Compared with WHO standards, boys of our study were taller especially at older ages. The percentiles of the BMI for our study samples were considerably lower than WHO standards. Conclusion: There are differences between our local growth charts for weight, height, and BMI with WHO standards. The local growth standards could be more precise for assessing growth problems in local and national settings. Due to notable differences between our results with WHO standards, future studies are warranted for constructing nationwide growth charts.
