Abstract

AGUILAR VALDES, Juan et al. Factores de riesgo asociados con el bajo peso al nacer: Municipio Boyeros, 1994-1995. Rev Cubana Hig Epidemiol [online]. 1999, vol.37, n.3, pp.122-126. ISSN 1561-3003.

A cohort analytic retrospective study was conducted so as to identify those risk factors associated with low birth weight (LBW) in the municipality of Boyeros from 1994 to 1995. 4 461 pregnant women were studied. 426 of them had children with LBW. The relative risk and the chi square test were used to know the magnitude and statistical significance of the association between the independent variables and the dependent variable. The percentage of risk attributable to the risk factor was also determined. Cervical uterine alterations, anemia in the third trimester and vaginal sepsis were the risk factors most associated with LBW and the ones that produced a greater impact on the reduction of the health problem. Being a smoker or an adolescent was also a risk factor; however, the number of deliveries or previous induced abortions and the low educational level of the mothers were not considered as risk factors.

Keywords : INFANT, LOW BIRTH WEIGHT; RISK FACTORS; ATTRIBUTABLE RISK; RELATIVE RISK (PUBLIC HEALTH).
