Size Estimation of People Who Inject Drugs and Their Geographical Distribution in Dogonbadan, Iran, During 2018: a Mapping Method

The aim of this cross-sectional study was investigation of geographical distribution and size estimation of people who inject drugs (PWIDs) in Dogonbadan, Iran, in 2018 using geographical mapping method. Data was obtained through interviewing primary and secondary key informants as well as field team observations. Population size was estimated by median in Stata software (version 14). GIS software (version 10.6.1) was used to prepare the density and distribution maps of the hotspots. We identified 52 hotspots of drug users; injection of drugs occurred in 31 of the hotspots. The prevalence of injecting drugs was 232.4 per 100,000 adults, while it was 21.9 and 441.8 among females and males, respectively. A large number of identified hotspots are not covered by harm reduction services. Increasing outreach teams, equipping of harm reduction centers, and moving them to the nearest location to hotspots are suggested.
