JUSTIFICATION The need to revise Indian Academy of Pediatrics (IAP) growth charts for 5- to 18-year-old Indian children and adolescents was felt as India is in nutrition transition and previous IAP charts are based on data which are over two decades old. PROCESS The Growth Chart Committee was formed by IAP in January 2014 to design revised growth charts. Consultative meeting was held in Novem...
Customized birth weight charts that incorporate maternal characteristics are now being adopted into clinical practice. However, there is controversy surrounding the value of these charts in the prediction of growth and perinatal outcomes. The objective of this study was to assess the use of customized charts in predicting growth, defined by body fat percentage, and perinatal morbidity. A total ...
Suppose that a target function f0 : R → R is monotonic, namely, weakly increasing, and an original estimate f̂ of the target function is available, which is not weakly increasing. Many common estimation methods used in statistics produce such estimates f̂ . We show that these estimates can always be improved with no harm using rearrangement techniques: The rearrangement methods, univariate and mu...
We give methods for the construction of designs for regression models, when the purpose of the investigation is the estimation of the conditional quantile function, and the estimation method is quantile regression. The designs are robust against misspecified response functions, and against unanticipated heteroscedasticity. The methods are illustrated by example, and in a case study in which the...
Growth reference charts are among the most sensitive and valuable tools for assessing the health and development of children. A questionnaire survey was answered by 16 of the 21 ministries of health in the Eastern Mediterranean Region countries (EMR) about their use of growth charts for children under 5 years. Most of the countries (13/16) used the NCHS/WHO charts and weight-for-age was the mos...
Human growth is both a target seeking process regulated by genes and environment, and a highly dynamic process that even under similar social and economic circumstances varies considerably both in amplitude (being short or tall) and tempo (maturing fast or slow). This has led to vivid discussions about which growth chart is the right chart to use. In contrast to wide-spread opinions emphasizing...
