THE SISTERHOOD METHOD OF ESTIMATING MATERNAL MORTALITY - THE MATLAB EXPERIENCE

This study reports the results of a test of validation of the sisterho od method of measuring the level of maternal mortality using data from a Demographic Surveillance System (DSS) operating since 1966 in Matla b, Bangladesh. The records of maternal deaths that occurred during 197 6-90 in the Matlab DSS area were used. One of the deceased woman's sur viving brothers or sisters, aged 15 or older and born to the same moth er, was asked if the deceased sister had died of maternity-related cau ses. Of the 384 maternal deaths for which siblings were interviewed, 3 05 deaths were correctly reported, 16 deaths were underreported, and t he remaining 63 were misreported as nonmaternal deaths. Information on maternity-related deaths obtained in a sisterhood survey conducted in the Matlab DSS area was compared with the information recorded in the DSS. Results suggest that in places similar to Matlab, the sisterhood method can be used to provide an indication of the level of maternal mortality if no other data exist, though the method will produce negat ive bias in maternal mortality estimates.
