ALPHA HIV Incidence and Mortality data, uMkhanyakude 2000-2016 - South Africa

Abstract
---------------------------

This dataset is created from harmonising longitudinal population-based demographic surveillance and repeated serological survey data collected by the uMkhanyakude study in South Africa. 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 Umkhanyakude site in South Africa includes two data files:

HIV incidence data
This 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 dates. Dates of birth are rounded to the 15th of the month, and all other dates are 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 the times (ages) of last negative test and first positive test have been provided.

Mortality data
This data file was created as described at https://gatesopenresearch.org/articles/1-4

摘要
---------------------------
本数据集由南非uMkhanyakude研究项目收集的纵向人口监测和重复血清学调查数据经协调整合而成。数据整合工作由ALPHA网络负责，该网络负责收集关于人口监测、口头尸检访谈、血清学和性行为调查的个体层级数据，以及来自卫生统计监测系统（HDSS）和医疗机构的相关联数据。

南非Umkhanyakude站点提供的数据包括两个数据文件：

HIV发病率数据
此文件包含居住在该研究区域、年龄在15-49岁之间、已进行一次阴性HIV检测且至少进行一次后续HIV检测的居民研究参与者的数据。为了描述不同居住地、不同年龄段和不同日历年期间的时间花费，可能将每个个体的数据拆分为多个观察值。所有时间均以事件发生时的年龄给出，而非具体日期。出生日期四舍五入至每月的15日，所有其他日期均以相同的偏移量进行调整，并使用四舍五入日期之间的时间差作为事件发生时的年龄。为了实现血清转化日期的多重插补，提供了最后一次阴性测试和第一次阳性测试的时间（年龄）。

死亡率数据
此数据文件的制作方法详述于https://gatesopenresearch.org/articles/1-4
