Abstract: Objective To discuss the impact of different markers on the estimation of MSM using the capture-recapture method.Methods From March to July 2013,MSM were captured from the their related network to estimate the site of this population,under the capture-recapture method.Two different markers were set in the process of first ‘capture'.Results The estimated numbers of MSM in Beijing were 239 258 (95％CI:48 932-429 584) and 115 731 (95％CI:78 153-153 309) when using the two markers under capture-recapture method.Conclusion The estimated size of MSM population varied greatly under different markers which called for the right selection on markers when using the capture-recapture method to estimate the size of specific population.
