The cases were children with ALL and children with malignancies other than ALL as the control. The study included 55 people in each case and control group. Data were obtained from medical records and questionnaires. Result: Influencing factors of childhood ALL are paternal age <25 years old (OR=3; 95% CI=0,96–9,3), two types of hydrocarbon products (OR=0,23, 95% CI=0,065–0,8) and none (OR=3,33, 95% CI=1,33–8,30) maternal exposure of hydrocarbons, preconception exposure (OR=0,3; 95% CI=0,12–0,74), and none (OR=3,5; 95% CI=1,41–8,67) maternal period exposure to hydrocarbons. BW, cigarette exposure, and insecticides exposure are not the influencing factors. Using the multivariate analysis, no factors was found to be the most influential.
