ABSTRACT

Child growth curves construction is a tiresome and time consuming process that has been done manually till now in our country. A review of methods for adjusting growth curve was carried out in order to automate this process. Techniques and procedures adopted by the World Health Organization (WHO) for the construction of child growth standards were applied to adjust waist circumference curve for boys from 8 to 19 years old. The methods recommended by WHO rest in the use of the computational package GAMLSS, which was developed in R, free and open source software for statistical computing.
