| dc.description.abstract | A whole range of techniques have been developed for estimating infant and child mortality from the information routinely recorded in maternity registers on age and reproductive history of delivering mothers. Among them, the best-known and most widely applied indirect technique was developed by William Brass. Using the baseline nformation from a birth cohort (Generation XXI assembled in the period 2005-2006 in the metropolitan area of Porto, North of Portugal, we addressed in this paper the following objectives: (1) to estimate the child mortality rates based on information about previous births and their survivorship among women recruited for this birth cohort; (2) to compare these indirect estimates with direct values retrieved from Portuguese vital statistics; (3) to analyse the potential of this birth cohort to generate plausible estimates of lifetable indicators. We retrieved data on mother’s age, previous live births prior to the current one, and number of surviving and deceased children from a group of multiparous women (n=3521). The data was divided into seven 5-year groups by maternal age and survival and death probabilities were computed for each group. Through the Brass method,we obtained estimates of probability of dying before attaining certain exact childhood ages, q(x), by using the multipliers k(i) as proposed by Palloni-Heligman. Then, a logit life-table system was used to derive lifetable indicators. Accordingly, probabilities of dying between birth and 2,3, 5 and 10 years were respectively: 4.0; 5.7; 7.3 and 9.6 per 1,000 children ever born, which were alocatted in time-period. These indirect estimates compared with the direct ones obtained from Portuguese vital statistics revealed that they were very similar. The life expectancy at birth was 77.6 years for both sexes, and the implied infant mortality was 4.0 per 1000 live births for Grand Porto during the period 2005-2006. The use of indirect method to analyze the potential of the Generation XXI cohort data in provide relevant information on reproductive issues, not available in the vital statistics, seems to be an important and effective tool, and promissory for analyzing the follow-up studies of this cohort held in 2009 and 2012. | por |
