National HIV prevalence estimates for sub-Saharan Africa: controlling selection bias with Heckman-type selection models
OBJECTIVES Population-based HIV testing surveys have become central to deriving estimates of national HIV prevalence in sub-Saharan Africa. However, limited participation in these surveys can lead to selection bias. We control for selection bias in national HIV prevalence estimates using a novel approach, which unlike conventional imputation can account for selection on unobserved factors. ME...
متن کاملEvaluation of geospatial methods to generate subnational HIV prevalence estimates for local level planning
OBJECTIVE There is evidence of substantial subnational variation in the HIV epidemic. However, robust spatial HIV data are often only available at high levels of geographic aggregation and not at the finer resolution needed for decision making. Therefore, spatial analysis methods that leverage available data to provide local estimates of HIV prevalence may be useful. Such methods exist but have...
متن کاملBayesian melding for estimating uncertainty in national HIV prevalence estimates
OBJECTIVE To construct confidence intervals for HIV prevalence in countries with generalised epidemics. METHODS In the Bayesian melding approach, a sample of country-specific epidemic curves describing HIV prevalence over time is derived based on time series of antenatal clinic prevalence data and general information on the parameters that describe the HIV epidemic. The prevalence trends at a...
متن کاملThe most severe HIV epidemic in Europe: Ukraine’s national HIV prevalence estimates for 2007
OBJECTIVE To revise the national HIV estimates and quantify the magnitude of the HIV epidemic in Ukraine at the end of 2007. DESIGN Internationally recommended methods-the Workbook and Spectrum-were employed to generate the estimates. This enables comparison of results with other countries using the same methodology. METHODS Estimation of the size of most at-risk populations nationally was ...
متن کاملAN ESTIMATION OF CLINICAL HYPERTHYROIDISM PREVALENCE IN THE NATIONAL AND SUB-NATIONAL LEVELS IN IRAN USING CLAIMS DATA
Background: The aim of this study was to estimate the prevalence of clinical hyperthyroidism at the national and sub-national levels using the claims data. Methods: National anti-thyroid medications (methimazole and propylthiouracil) sales data in 2014 were extracted from pharmaceutical sales data that were reported by Iran's Food and Drug Administration (FDA). By using prescriptions data of S...
