Comparative Study[Risk factors for low birth weight and intrauterine growth retardation in Santiago, Chile].
An epidemiologic case-control study to ascertain the determinants of low birthweight was carried out in Santiago, Chile, from January to December 1989. The cases were defined as livebirths < 2500 g. The controls were livebirths > or = 2500 g of birthweight. ⋯ Only nutritional factors were related to LBW in preterm group. Women who delivered a LBW or IUGR infant were more likely to have fewer pregnancies, a history of previous LBW, lower prepregnancy weight and lower gestational weight gain. ICP was associated with an elevated risk of LBW that was independent of gestational age.

Diverse indicators were used to examine medical research in Chile. According to participation in Fondecyt projects, it was concluded that 420 persons were involved in medical sciences research and that 41.9% of them had no postgraduate title. During the eighties, there was a clear aging of the community dedicated to medical research. ⋯ The University of Chile published the greatest number of articles, followed by the Catholic University and, with a remarkable lower amount, other Universities. The impact of the published articles in Clinical Medicine and Biomedical Sciences was calculated from the citations that they generated from 1986 to 1988. Likewise, the articles registered in 1985 with the higher citation indexes were identified.
