Controversias en la elección de curvas de crecimiento para evaluar los recién nacidos colombianos

The growth curves allow us to compare the growth pattern of each child with that which is considered appropriate for their age group. In newborns, correct classification of weight growth makes it possible to treat and prevent infant morbidity and mortality associated with growth deviations on time. Currently, there are multiple types of curves (standardized, local or international reference, personalized), and it is not sure which best evaluates newborns' growth. The evidence indicates that the growth pattern of each country or region must be known before adopting any curve. In Colombia, few studies on local curves and international curves have been adopted without having validated them for our population. It is essential to generate local curves and knowing the necessary steps to adopt an international curve because: 1) International curves can lead to classification errors due to representativeness problems. 2) Consequently, it is necessary to know the local growth pattern to know if the international curve fits our population. Finally, 3) If it is mandatory to adopt a growth curve, it is essential to evaluate the methodology used for its creation, to compare the growth patterns of the selected curve and the local curve, and to know the clinical context in which the curve will be applied. These aspects will make it possible to choose a suitable instrument to take correct preventive or therapeutic measures
