OBJECTIVES: to evaluate infant mortality in very low birth weight newborns from a public hospital in Rio de Janeiro, Brazil (2002-2006). METHODS: a retrospective cohort study was performed using the probabilistic linkage method to identify infant mortality. Mortality proportions were calculated according to birth weight intervals and period of death. The Kaplan-Meier method was used to estimate overall cumulative survival probability. The association between maternal schooling and survival of very low birth weight infants was evaluated by means of Cox proportional hazard models adjusted for: prenatal care, birth weight, and gestational age. RESULTS: the study included 782 very low birth weight newborns. Of these, (28.6%) died before one year of age. Neonatal mortality was 19.5%, and earlyneonatal mortality was 14.9%. Mortality was highest in the lowest weight group (71.6%). Newborns whose mothers had less than four years of schooling had 2.5 times higher risk of death than those whose mothers had eight years of schooling or more, even after adjusting for intermediate factors. CONCLUSIONS: the results showed higher mortality among very low birth weight infants. Low schooling was an independent predictor of infant death in this low-income population sample.

Almost All

About one tenth of all infant deaths occur in babies weighing less than 500 g at birth, almost all of whom die very shortly thereafter. In 1983, when the United States reported 3,638,933 live births, 4,368 of them were less than 500 g; that year there were 26,507 neonatal deaths. This means that slightly more than 0.1% of all live births contributed to 17% of neonatal mortality. Given this order of magnitude, any change in the numbers relating to these tiny babies can have a disproportionate influence on reported infant mortality and on interstate comparisons. Two questions promptly arise. How accurate and meaningful are the data regarding babies born weighing less than 500 g? What can be done to decrease the deaths in this category? Wilson et al1 call attention to how the number of very low birth weight infants reported by a state may be affected by the state's definition of a live birth.

Objective. To determine whether known maternal risk factors for low birth weight directly contribute to infant mortality among very low birth weight infants. Design. Retrospective population-based, case-control study. Setting. Four hospitals in the Oakland, California, area: one community, two private, one health maintenance organization. Participants. All live-born singleton very low birth weight (<1500 g) infants born to Oakland residents over a 3-year period. Cases were infants who died before their first birthday, identified by computerized linkage of birth and death certificates. For each case, a surviving control was selected to match for birth weight, sex, and race. Forty matched pairs were identified in total. Outcome Measures. Prevalence of maternal risk factors among cases versus controls. Results. After controlling for other factors known to influence either birth weight or infant mortality, maternal cocaine use (odds ratio [OR] = 5.43), prior infant death (OR = 27.14), and planned pregnancy (OR = 6.33) were significantly associated with the survival of very low birth weight infants. Conclusions. Some maternal risk factors for low birth weight confer a survival advantage to very low birth weight infants. Our data reveal that maternal cocaine use is independently associated with survival among this subset of infants. Prior research supports the observed relationship as well as the scientific plausibility of a cocaine-mediated survival advantage among premature infants. Our study also showed both planned pregnancy and prior infant death to be independently associated with infant survival among this subset of infants, sugesting that maternal behaviors may play a role in determining birth weight-specific mortality. These data should be systematically evaluated to better define their relationship to infant mortality.
