Biobehavioral survey using time location sampling among female sex workers living in Ghana in 2020 [PDF]

Frontiers in Public Health
BackgroundThe HIV epidemic in Ghana is characterized as a mix of a low-level generalized epidemic with significant contributions from transmission among female sex workers (FSW) and their clients.

Improving Underestimation of HIV Prevalence in Surveys Using Time-Location Sampling. [PDF]

J Urban Health, 2021
We sought to find a method that improves HIV estimates obtained through time-location sampling (TLS) used to recruit most-at-risk populations (MARPs). The calibration on residuals (CARES) method attributes weights to TLS sampled individuals depending on the percentile to which their logistic regression residues belong.

Statistical methods for the analysis of time-location sampling data. [PDF]

J Urban Health, 2012
Time-location sampling (TLS) is useful for collecting information on a hard-to-reach population (such as men who have sex with men [MSM]) by sampling locations where persons of interest can be found, and then sampling those who attend. These studies have typically been analyzed as a simple random sample (SRS) from the population of interest.

Prevalence and associated risk factors of HIV infections in a representative transgender and non-binary population in Flanders and Brussels (Belgium): Protocol for a community-based, cross-sectional study using time-location sampling. [PDF]

PLoS One, 2022
Introduction HIV prevalence and sexual risk have been estimated very high for transgender people. However, the limited sampling and data collection methods used in current research on transgender people potentially led to overrepresentation and generalisation of people at risk for HIV.

Reaching men who have sex with men: a comparison of respondent-driven sampling and time-location sampling in Guatemala City. [PDF]

AIDS Behav, 2013
We present a comparison of respondent-driven sampling (RDS) and time-location sampling (TLS) for behavioral surveillance studies among men who have sex with men (MSM). In 2010, we conducted two simultaneous studies using TLS (N = 609) and RDS (N = 507) in Guatemala city.

Time location sampling in men who have sex with men in the HIV context: the importance of taking into account sampling weights and frequency of venue attendance. [PDF]

Epidemiol Infect, 2018
AbstractSex between men is the most frequent mode of HIV transmission in industrialised countries. Monitoring risk behaviours among men who have sex with men (MSM) is crucial, especially to understand the drivers of the epidemic. A cross-sectional survey (PREVAGAY), based on time-location sampling, was conducted in 2015 among MSM attending gay venues ...

Reaching black men who have sex with men: a comparison between respondent-driven sampling and time-location sampling. [PDF]

Sex Transm Infect, 2012
ObjectivesThe authors explored whether respondent-driven sampling (RDS) can generate a more diverse sample of black men who have sex with men (MSM) than time-location sampling (TLS) by comparing sample characteristics accrued by each method in two independent studies.MethodsThe first study exclusively recruited black MSM through RDS (N=256), while the ...
