Drug addiction of street children is an important issue for studying the social and health status of a country. The prevalence of drug addiction is mainly seen in the urban areas of Bangladesh like Dhaka City, the capital of Bangladesh than that of the rural areas. So, it is imperative to know the
factors which are influencing the drug addiction among street children of Dhaka city in Bangladesh for the greater interest of the policy makers as well as planner of Government and Non-Government Organizations (NGOs). Data were collected from 1108 street children in different places of Dhaka City using a comprehensive questionnaire. χ2-test was used to determine the association of drug addiction among the various background characteristics of the street children. In this study, logistic regression model was also used to identify the determinants of drug addiction among the street children. The analysis found that the street working children (OR=0.465, CI: 0.222-0.977) and children from street families (OR=0.352, CI: 0.105-1.179) were less likely drug addicted than street living children. The drug addiction of street children interviewed at railway station/bus stand/launch terminal (OR=0.044, CI: 0.018-0.111), kachabazar (OR=0.027, CI: 0.008-0.086) and park/institution (OR=0.046, CI: 0.014-0.156) respectively was less likely than the street children interviewed at mazar. The street children born in urban area (OR=1.663, CI: 0.942-2.934) were more likely drug addicted than the street children born in rural area. Smoker street children (OR=13.167, CI: 6.881-25.196) were more probable drug addicted than non-smoker street children. Government of Bangladesh and NGOs should take necessary steps to keep the street children away from the vulnerable places like mazar, railway station/bus stand/launch terminal etc. and arrange institutional care for them especially those who born in urban areas. As almost all drug addicted street children are smoker, so the policy maker should take proper measures to reduce the smoking practices of street children.
