摘要

Background and aim: Various methods of estimating the size of hidden populations are prone to different degrees of information biases. This study aimed to assess such biases.Methods: We estimated the prevalence of risky behaviors using direct, modified network scale-up (NSU) and proxy respondent method (PRM) among college students.Results: The network sizes of the male and female students were 25.8 and 29.5. We found alcohol use was the most prevalent risky behaviors among males (PRM: 18.12%, NSU: 8.68%, direct: 13.4%) and the extra-marital sex was the most prevalent one among females (PRM: 3.47%, NSU: 0.95%, direct: 1.4%). Based on PRM, intravenous drug use (IDU) was the least prevalent behavior among college students.Conclusion: We concluded that direct and NSU methods might underestimate the results.
