Abstract
Objectives: Around the aim of gaining knowledge on the secular trends in nutritional status of the Spanish population, we found a collection of historical records compiled by La Institución Libre de Enseñanza and their alumni association along 47 years. These data had been collected from boys and girls attending summer camps, with a policy of improving health of children with unfavorable socioeconomic conditions. The objective is to extract all possible information about growth changes, and eventually any interpretation related to status of the originating families.
Materials and methods: Primary data were collected from both unpublished manuscripts containing the original records and publications of the organizing institutions. They had been gathered from 86 summer camps in Spain from 1887 to 1934. In these camps, detailed anthropometric data were collected from every attendee, including body height and weight. The sample population amounts to 1,791 boys and 1,281 girls, between 7 and 16 years of age.
Results: Body height and weight, pooled by camp year, age and sex, displayed variable secular increases. A similar observation appears for the body mass index (BMI). As a complement, a comparison was done to contemporary published references from both Spanish and international studies.
Discussion: Height, weight, and BMI from the camps may be judged as retardation of growth and malnutrition by modern standards but it is not the case when coetaneous references are considered: no overall significant differences were found with respect to several publications from Spanish and European populations.
