Demographic Surveillance System Data
Abstract
This dataset is created from harmonising longitudinal population-based demographic surveillance and repeated serological survey data collected by an Kisesa HIV open cohort Study in Mwanza, Tanzania. The data harmonisation is coordinated by the ALPHA Network which curates individual-level data on demographic surveillance, verbal autopsy interviews, serological and sexual behaviour surveys, and individually-linked data from HDSS and medical facilities.
The data from the Kisesa site in Tanzania includes two data files:
HIV incidence data data file:
This data file includes data on resident study participants aged 15-49 who have had one negative HIV test and at least one subsequent HIV test done within the study for research purposes. Data may be split into multiple observations for each person to describe time spent in different residencies, different age groups and different calendar year periods.
All timings are given as age at event, instead of the dates. Dates of birth were rounded to the 15th of the month, and all other dates were offset by the same amount and the time elapsed between the rounded dates is used as the age at event.
To enable multiple imputation of seroconversion dates we have provided the times (ages) of last negative test and first positive test.
