The reliability of sexual partnership histories: implications for the measurement of partnership concurrency during surveys.
OBJECTIVES To measure the reliability of sexual partnership histories collected during survey interviews and to assess the impact of measurement error on survey estimates of partnership concurrency. METHODS We used sociocentric data collected on Likoma Island (Malawi). Up to five of the respondents' most recent sexual partners were identified in population rosters. We assessed interpartner ag...
متن کاملShort-term Mobility and Increased Partnership Concurrency among Men in Zimbabwe
BACKGROUND Migration has long been understood as an underlying factor for HIV transmission, and sexual partner concurrency has been increasingly studied as an important component of HIV transmission dynamics. However, less work has examined the role of short-term mobility in sexual partner concurrency using a network approach. Short-term mobility may be a risk for HIV for the migrant's partner ...
متن کاملCoital frequency and condom use in monogamous and concurrent sexual relationships in Cape Town, South Africa
INTRODUCTION A decreased frequency of unprotected sex during episodes of concurrent relationships may dramatically reduce the role of concurrency in accelerating the spread of HIV. Such a decrease could be the result of coital dilution - the reduction in per-partner coital frequency from additional partners - and/or increased condom use during concurrency. To study the effect of concurrency on ...
متن کاملAnalysis and simulation of a stochastic, discrete-individual model of STD transmission with partnership concurrency.
Deterministic differential equation models indicate that partnership concurrency and non-homogeneous mixing patterns play an important role in the spread of sexually transmitted infections. Stochastic discrete-individual simulation studies arrive at similar conclusions, but from a very different modeling perspective. This paper presents a stochastic discrete-individual infection model that help...
متن کاملTiming Is Everything: International Variations in Historical Sexual Partnership Concurrency and HIV Prevalence
BACKGROUND Higher prevalence of concurrent partnerships is one hypothesis for the severity of the HIV epidemic in the countries of Southern Africa. But measures of the prevalence of concurrency alone do not adequately capture the impact concurrency will have on transmission dynamics. The importance of overlap duration and coital exposure are examined here. METHODOLOGY/PRINCIPAL FINDINGS We co...
