The aim of this study was to measure the association between substance use disorder and demographic, social and behavioral factors in Yasuj city, located at southwest of Iran. Methods As the second phase of a previously published study, this case-control study was conducted in 2015–2016 on 362 addicted participants and 207 controls (with no history of substance use disorder). The control group was selected from male hospital visitors in Yasuj city during the same period of selection of the case group. The required information was collected via a self-administered questionnaire. Results Based on the results of multivariate analysis, significant associations were found between the number of sisters (OR = 0.82, 95%CI = 0.68 to 0.99, P = 0.04), history of smoking (ORyes/no = 19.89, 95%CI = 10.02 to 39.49, P < 0.001), leisure time activity (ORwith friends/home = 8.98, 95%CI = 3.99 to 20.19, P < 0.001) and substance use disorder.
