Measuring maternal mortality by expressing maternal deaths per live birth, rather the original sisterhood method. The total ltr of maternal death was 9% (or about 1 in 11) and using 73 as the tfr for all the states, the average mmr in the study area was 1,271 maternal deaths per 100,000 live births, 95% ci was 1,152-1,445 maternal deaths per 100,000 live births. Household surveys: the sisterhood method (indirect and direct) sibling survival histories incorporated into household surveys provide the opportunity to capture maternal deaths in developing countries where civil registration is incomplete or non-existent.
The direct method of calculating maternal mortality presented here relies on detailed information about respondents' sisters, including the current age of all surviving sisters, the age at death of dead. Household surveys (sibling-based and sisterhood surveys, reproductive-aged mortality studies and verbal autopsies focusing on maternal death), and prospective surveillance of deaths of reproductive-aged women using community-based informants. The sisterhood method of calculating maternal mortality, which relies on surviving sisters to report on sibling mortality, is easy to use in the field and provides fast calculations of maternal mortality in settings with scarce data on vital statistics.
Where, for a given time period, md is maternal deaths, lb is live births, fpra is the person-years lived by the female population of reproductive age, and gfr is the general fertility rate expressed per 1,000 women of reproductive age. The maternal mortality rate can only be compared across sources for zambia where the savvy estimate of the maternal mortality rate is similar to that obtained using the direct sisterhood method for pregnancy-related deaths in the 2013-14 dhs and the 2010 census, and a bit lower than the estimate obtained from the 2007 dhs (although likely. This study estimated the mmr, the percentage of deaths due to maternal causes, and the lifetime risk of maternal death in three rural communities in zaria emirate, using the indirect sisterhood method. The maternal mortality ratio can be calculated by dividing recorded (or estimated) number of maternal deaths by total recorded (or estimated) number of live births in the same period and multiplying by 100,000. The sisterhood method, a community-based survey technique, was used to estimate the life time risk of a woman dying a maternal death in southern malawi.
Method: as part of a survey of 851 households, information on the number of sisters of respondents who died of pregnancy-related causes was collected and the data were used to calculate maternal mortality statistics using the sisterhood (an indirect) method. The sisterhood method is an indirect technique used to estimate maternal mortality in developing countries, where maternal deaths are often poorly registered in official statistics it has been. Nigeria using the sisterhood method reported an mmr of 1,049 maternal deaths per 100,000 live births (95% ci: 1021-1136) in zamfara state, and 1,271 maternal deaths.
The sisterhood method for estimating mmr, which involves collecting data on maternal deaths among sisters of respondents, is an ideal method for such settings because it requires a smaller number of respondents than cohort studies, and data collection is quick and relatively simple. Methods we used data from 144 countries and territories (65 with vital registration data and 79 with nationally representative survey data) to calculate the proportion of maternal deaths among deaths of females of reproductive age (pmdf) for each 5-year age group from 15-19 to 45-49 years. The objective of this study was to estimate the lifetime risk (ltr) of maternal death and the maternal mortality ratio (mmr) in jigawa state, northern nigeria using the sisterhood method. We calculated several indicators of maternal mortality: the maternal mortality rate (mmrate) which is the number of maternal deaths per 1,000 women of reproductive age, the proportion of maternal deaths among deaths of females of reproductive age (pmdf) and the maternal mortality ratio (mmratio) which is the number of maternal deaths per. Specifically, with the indirect sisterhood method, the number of households that need to be visited in order to obtain information on large numbers of women who have reached reproductive age is relatively small 58 given that questions are asked about the deaths of adult sisters, both methods actually measure pregnancy-related deaths rather.
The maternal mortality ratio is the most widely used measure of maternal deaths it measures obstetric risk (ie, the risk of dying once a woman is pregnant) it therefore omits the risk of being pregnant (ie, fertility, in a population, which is measured by the maternal mortality rate or the lifetime risk) (graham and airey, 1987. The sisterhood method for estimating the mmr is therefore an ideal method for estimating mmr in such settings as it requires a smaller number of respondents compared with vital registration and cohort studies the data collection for this method is retrospective, simple, quick, and based on information about maternal deaths among the sisters of the respondents [6, 7] the method cannot be used to assess trends, however. Source: who (1997c) the sisterhood method for estimating maternal mortality: guidance for potential users who: geneva 322 calculating mmr in indirect sisterhood method the maternal mortality ratio (mmr) is a measure of the risk of death directly related to the pregnancy once a woman has become pregnant.
The sisterhood method is a household survey to estimate maternal deaths recommended by the world health organization although maternal deaths are a major problem in developing countries, high quality data are rare yet, numbers are needed for planning in order to reduce the problem of maternal death. The sisterhood method is an indirect measurement technique of the kind frequently used for a variety of demographic parameters which has been adapted to maternal mortality it reduces sample size requirements because it obtains information by interviewing respondents about the survival of all their adult sisters. For countries with high maternal mortality and fertility rates, graham and colleagues developed an indirect sisterhood method for calculating maternal mortality indices this method is widely used in africa and asia to provide community-based maternal mortality estimates [ 13 - 15 .
The direct sisterhood method is a variant of the indirect sisterhood method, and is currently used by demographic and health surveys (dhs) while it requires larger sample sizes than its predecessor, the advantage of the direct method is the targeting of a more limited reference period for sister deaths. Questions are used to calculate the proportion of sisters dying of maternal causes, which is then used to derive a variety of indicators of maternal mortality one of the major advantages of the sisterhood method is the relatively small. Maternal mortality in kigoma is high when compared to other regions in tanzania the sisterhood method is relatively simple and convenient for estimating maternal mortality in resource-poor countries.
