ARTnet is an anonymous cross-sectional web-based survey conducted from 2017 to 2019 of HIV-related risk behaviors, testing, and use of prevention services among men who have sex with men (MSM) in the United States. It recruited MSM who have completed the American Men’s Internet Survey (AMIS) study, and therefore, the dataset contains variables merged from that study as well. Full access to the dataset from ARTnet will allow the researchers to conduct analyses and disseminate results using the data.
For further details on the ARTnet Study, you can read the descriptive paper "Egocentric Sexual Networks of Men Who Have Sex with Men in the United States: Results from the ARTnet Study" by Weiss et al. in Epidemics. See the ARTnet Scientific Publications section below for further details.
Access to the data requires a Memorandum of Understanding (MOU) that outlines the personnel analyzing the data and purposes of the data analyses. This dataset may not be shared without the consent of the ARTnet Study PI (Samuel Jenness, Emory University) as outlined in an MOU. Please contact the PI by email (mailto:samuel.m.jenness@emory.edu) to request access. A template MOU will be sent; after review access to the ARTnet dataset will be provided via Github.
The ARTnet package depends on the ARTnetData package, which contains the limited use public dataset. Because of the restrictions of the dataset, the ARTnetData package must be installed separately, to fully utilize the ARTnet package, using the following directions.
A set of built-in analyses are available within the package as well to experiment before gaining access to the full data-set. See below.
The suggested method for accessing the dataset is to directly install the ARTnetData package in R, using the remotes package. First, because this repository is private, installing this package requires a Github Personal Access Token.
You can use the usethis package to create a new PAT for use in R, like this:
usethis::create_github_token()Copy the PAT, and then put it in your .Renviron file as a system variable called GITHUB_PAT. You can open your .Renviron like this:
usethis::edit_r_environ()Your .Renviron file should contain a line like this, but with your own unique PAT on the right-hand side.
GITHUB_PAT=XXXXXXNote that there are other potentially more sophisticated and secure ways to manage your Github PAT, as detailed in the usethis vignette.
After creating a PAT, restart R/Rstudio and use the remotes package to install ARTnetData.
remotes::install_github("EpiModel/ARTnetData")This R package comes with two included datasets, a wide-form dataset (rows = study participants) and a long-form dataset (rows = partnerships, with multiple rows per unique study participant). The suggested method for accessing the dataset is to directly install the ARTnetData package in R, using the remotes package as follows:
library("ARTnetData")
d <- ARTnet.wide
l <- ARTnet.longThe built-in dataset names for the two datasets are ARTnet.wide and ARTnet.long, and they are "lazy loaded" into global memory when the ARTnetData package is loaded. To use or modify the datasets, you might start by assigning those datasets short-hand names. Then any R operations may be performed.
str(d)
str(l)The ARTnet package contains standardized scripts to analyze the ARTnet data for the purposes of parameterizing the epidemic modeling with EpiModel and EpiModelHIV. There are three primary functions, detailed below, that conduct statistical analysis of the data for a specific target population of MSM defined by geography, age, and race/ethnicity. Users may also conduct analyses of the ARTnet dataset without the ARTnet package, but this package automates several standard analyses needed for many epidemic modeling projects.
The ARTnet package may be installed with the remotes package:
remotes::install_github("EpiModel/ARTnet", build_vignettes = TRUE)Some of the example uses are then as follows:
# 1. Epistats: Specify geographic features, as well as race stratification
# and total age range
epistats <- build_epistats(geog.lvl = "city",
geog.cat = "Atlanta",
race = TRUE, age.limits = c(30, 50),
age.breaks = c(35, 45))
# 2. Netparams: Specify age categories if needed, or let ARTnet determine
age categories by number of categories desired
netparams <- build_netparams(epistats = epistats, smooth.main.dur = TRUE)
# 3. Netstats: Finalize network setup
netstats <- build_netstats(epistats, netparams, expect.mort = 0.0005,
network.size = 1000, edges.avg = TRUE)More details of which may be found in the package vignette:
vignette(package = "ARTnet")For EpiModelHIV models, the epistats and netstats object are required. To
experiment with it without access to ARTnetData, ARTnet provides an example
for each. They are the result of the following calls:
epistats <- build_epistats(
geog.lvl = "city",
geog.cat = "Atlanta",
init.hiv.prev = c(0.33, 0.137, 0.084),
race = TRUE,
time.unit = 7
)
netparams <- build_netparams(
epistats = epistats,
smooth.main.dur = TRUE
)
netstats <- build_netstats(
epistats,
netparams,
expect.mort = 0.000478213,
network.size = 1e3
)They can be accessed copied locally with:
file.copy(
system.file("netstats-example.rds", package = "ARTnet"),
"netstats.rds"
)
file.copy(
system.file("epistats-example.rds", package = "ARTnet"),
"epistats.rds"
