    Abstract

    Magu Demographic Surveillance System

    The TAZAMA DSS study was set up in 1994 as part of a Tanzania - Netherlands collaboration to provide a framework for interventions to combat the spread of HIV, and was then known as TANESA. The original focus was on measuring the effects of prevention activities. Since 2005 the project has broadened its focus to include provision of a frame for studies involving HIV treatment and care.

    The demographic surveillance system collects information on births and deaths and movements in and out of the households. It helps to understand the population dynamics in the study area including fertility, mortality and migration patterns. It provides information on the structure of families that live together. The demographic surveillance system study is also used to identify people who are eligible to participate in the serological-surveys (the right age group, and continuously resident rather than just visiting). It provides the data for calculating the denominators for demographic rates.

    The objectives of the Magu DSS
    · To measure child and adult mortality and fertility in the general population,
    · To lay a reliable foundation for HIV epidemiological surveys by registering people's mobility and mortality
    · To assess the leading causes of death through verbal autopsy
    · To assess the potential changes in family structure due to the adult mortality (e.g. orphan hood)
    · To provide Vital Data to the Ward and District authorities for planning purposes.

    Verbal Autopsy
    In the Magu DSS, Verbal autopsy work started in 1994 just after the DSS's baseline census. VA interviews are carried out after every round of the DSS. The available data are for verbal autopsies corresponding to the DSS rounds done till 2010. Three questionnaires are used; one for neonates 0-28 days, one for children aged 29 days-14years and the one for adults 15 years and over.

    Data Collection Notes

    Enumerators were trained initially and then refresher trainings conducted prior to each surveillance round.

    Data processing

    Data Editing

    Data editing took place at different stages of the data processing. On data entry, data consistency and plausibility were checked against set validation rules at database level. For errors identified, the questionnaire was referred back to the field for revisit and correction. For data that could be corrected on consulting the data scientists were done internally.
