[Analysis of Related Factors Affecting the Nosopoiesis of Childhood Acute Leukemia].

Objective: To analyze the related factors affecting the nosopoiesis of childhood acute leukemia from the perspective of indoor environmental exposure, behavior and lifestyle.
Methods: The clinical data of 64 children with acute leukemia were retrospectively analyzed, and 50 healthy children were selected as the control group during the same period. The basic data of children, indoor environment, behavior and lifestyle of parents in 2 groups were recorded. Univariate and multivariate logistic regression analysis were used to analyze the related factors affecting the incidence of childhood acute leukemia, and the OR (95%CI) value was calculated.
Results: The unvariate analysis showed that the daily wine-drinking rate of father and pesticide use rate in acute leukemia group were significantly higher than those in control group (P<0.05). Multivariate Logistic regression analysis showed that indoor ventilation during summer sleep of children (OR=0.35, 95%CI: 0.14-0.88) and contact with other children before 3 years old (OR=0.34, 95%CI: 0.18-0.65) were protective factors for provention of childhood acute leukemia (P<0.05). Mothers had a history of exposure to chemical substances (OR=3.68, 95%CI: 1.64-8.27), and children had a history of exposure to chemical substances (OR=3.84, 95%CI: 1.64-9.01), family had internal decoration history after child birth (OR = 1.38, 95%CI: 1.05-1.81) and family uses of pesticides (OR=2.17, 95%CI: 1.08-4.36), all these factors were independent risk factors for acute leukemia (P<0.05).
Conclusion: Indoor environmental exposure, behavior and lifestyle of children and parents may be closely related with the nosopoiesis of childhood acute leukemia.
