Brief Summary

INMA - INfancia y Medio Ambiente \[Environment and Childhood\] Project is a research network of several Spanish groups that created a project with the aim to study the paper of the more relevant environmental pollutants in the air, water and diet during the pregnancy and beginning of life, and their effects in the growth and development.

The INMA Project is based on the experience acquired by groups that studied several cohorts with different objectives: the cohort of Riera d'Ebre (n=102), an area with high levels of organochlorine compounds and mercury, evaluated the relationship between these exposures and the neurological development of the children; the cohort of Menorca (n=492), studied the relationship between the early exposure to irritating of the air and allergens with the development of allergy and asthma; and the cohort of Granada (n=668), that studied the incidence of reproductive disorders in men in relation to the exposure to endocrine disruptors.

Based on the experience of these previous cohorts, other 4 new cohorts were designed to evaluate the impact of environmental exposures in children's health: Valencia (n=787), Sabadell (n=622), Asturias (n=485) and Gipuzkoa (n=612), that followed the same protocol. The population of the study are pregnant women of the general population who lived in each area of study (Ribera d' Ebre, Menorca, Granada, Valencia, Sabadell, Asturias, and Gipuzkoa and their children. Each cohort had different periods and types from recruitment. In the cohorts of Ribera d'Ebre and Granada, the mothers were recruited during the admission to the hospital at the moment of the childbirth. In Ribera d'Ebre, the recruitment was between March 1997 and December 1999, whereas in Granada it was between October 2000 and July 2002. In Menorca, all the eligible women who went to the prenatal visit in some of the sanitary centres of the island (private or public) were invited to participate in the study, and the recruitment lasted a year starting in July 1997. In the 4 new cohorts the recruitment took place during the first prenatal visit (between weeks 10 and 13 of gestation) in the public hospital of reference or in the health centre of the area. The periods of recruitment went from February 2004 to June 2005 in Valencia, from July 2004 to July 2006 and May 2007 to July 2007 (there was an additional round of recruitment) in Sabadell, from May 2004 to June 2007 in Asturias, and from April 2006 to January 2008 in Gipuzkoa.
