ALPHA HIV Incidence and Mortality Data, Manicaland 1995-2016 - Zimbabwe

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

The Manicaland dataset is created from harmonising longitudinal population-based demographic surveillance and repeated serological survey data collected by an Open Population Cohort Study in Manicaland, Zimbabwe. 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 Manicaland site in Zimbabwe is provided in 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 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 the times (ages) of last negative test and first positive test have been provided
Mortality data:
This data file was created as described here https://gatesopenresearch.org/articles/1-4

摘要
---------------------------
曼尼卡兰数据集源自于对津巴布韦曼尼卡兰地区开放人群队列研究中纵向人口普查与反复进行的血清学调查数据的整合。该数据整合工作由ALPHA网络协调进行，该网络负责整理关于人口普查、口头尸检访谈、血清学及性行为调查的个体级数据，以及来自健康与人口数据系统（HDSS）和医疗机构的相关个体链接数据。

津巴布韦曼尼卡兰站点提供的数据包含两个数据文件：

HIV发病率数据：
此文件包含居住在研究区域、年龄在15至49岁之间、曾经接受过一次阴性HIV检测且在研究期间至少进行过一次后续HIV检测的参与者数据。针对每位个体，数据可能被拆分为多个观察值，以描述其在不同居住地、不同年龄段以及不同日历年期间所花费的时间。所有时间均以事件发生时的年龄给出，而非日期。出生日期四舍五入至每月的15日，所有其他日期均按相同方式调整，且使用四舍五入日期之间的时间差作为事件发生时的年龄。
为便于进行血清转化日期的多重插补，提供了最后一次阴性检测和第一次阳性检测的时间（年龄）。
