Childhood as a value and a problem in the campaigns for health at the beginning of the twentieth century in Spain

: The paper explores how, through a process that began in the last decades of the nineteenth century and continued during the first part of the present century, especially in the 1920's infancy and infant health were regarded as objects of great value and as a social problem. The child's body was studied and analyzed by doctors, a situation that had important repercussions in other spheres of social life. Children were considered to have a series of characteristics which formed, as a whole, an ideal model within the family and home setting. Care, protection and intervention are the three components underlying the sanitary reform process that supported the health and welfare of children in Spain during this period.
