BUSCADOR RECOLECTA

Data were collected from healthy children (6 to 18 years old) from public schools of middle and low socioeconomic levels in different parts of Argentina, Cuba, Spain, Mexico, and Venezuela. The LMS method was applied to calculate smoothed percentiles depending on age and sex groups. Comparisons were established with references from the United States, Colombia, India, China, Australia, Kuwait, Germany, Tunisia, Greece, and Portugal.

Waist circumference constitutes an indirect measurement of central obesity in children and adolescents. The aim was to provide percentiles of WC for Hispanic-American children and adolescents, and compare them with other international references.

Data were transcribed from the archives of general anthropological forms collected by MPN between 1887 and 1924. Data were validated, filtered and finally pooled according to children age and the year of measurement. They were analysed in search of any secular trends and also in comparison with more contemporary published data from both national and international populations.

Unpublished primary data for height and sitting height were collected from historical records of schoolchildren attending summer camps organized by the Spanish National Pedagogic Museum between 1887 and 1924. This work assesses a possible secular change in proportion between lower limbs and torso (cormic index), also comparing to later studies up to the present.

Data were transcribed from the archives of general anthropological forms collected by MPN between 1900 and 1925. Data were validated, filtered and finally pooled according to children age and the year of measurement. They were analysed in search of any secular trends and also in comparison with more contemporary published data from Spanish populations.

Unpublished primary data for hand grip strength were collected from historical records of schoolchildren attending summer camps organized by the Spanish National Pedagogic Museum between 1900 and 1925. This work assesses a possible secular change in this dynamometric parameter, also comparing to later studies up to the present.
