Abstract: Child labour remains a widespread problem in the world today. It is evident that, though the child laborers work at various health hazardous situations but they have very little access to primary health care and the overall health condition and nutritional status are very low. This study aims at investigating the factors that influences the health complications of the child laborers during research. For this the primary data were collected using purposive sampling technique by scheduled questionnaire from some selected areas of Rangpur district, Bangladesh. Some statistical techniques like percentage distribution,χ 2 test and logistic regression method have been applied in this study. The percentage distribution represents the overall socio-economic, demographic and health related characteristics of the child laborers. The χ 2 test shows the degree of significance of the association between health complications and some selected explanatory variables. The logistic regression analysis shows that working hour per day, place of work and age at the time of entrance to work appeared to be the most significant factors in determining the likelihood of facing health complications during research.
