Abstract
In 1982, a birth cohort study1 was initiated in Pelotas, a Southern Brazilian city with a current population of 323 000 inhabitants. It started as a perinatal survey and later became one of the largest and longest running birth cohorts in the developing world.2 With the success of this initial study, our group decided to propose a second birth cohort, to be launched 10 years later. Due to delayed funding, the new cohort could only start in 1993.3 Funding for the new cohort was obtained from the European Economic Commission, in a collaboration that included the London School of Hygiene and Tropical Medicine and the Escuela Andaluza de Salud Publica from Granada.
