An effect evaluation on the model of integrated drowning interventions for the floating children in Ningbo City / 预防医学

ABSTRACT

Objective This study aimed to evaluate the model of integrated drowning interventions for the floating children in Ningbo City.Methods A two -year program of integrated drowning intervention had been carried out in Ningbo City since 2013,and the floating children in Jiangbei District and Yinzhou District were selected as the experiment and control group respectively.Baseline and final survey was all conducted in these two groups.A total of 7 736 and 7730 students from 1 st -9 th grade in the Migrant Workers'Children Schools were recruited by multi -stage random sampling and surveyed by the self -reported questionnaires in these two surveys respectively.The unconditional logistic regression model was adopted mainly for the multivariate analysis.Results The incidence rate of non -fatal drowning for the floating children in the experiment group after intervention was 4.45%,being significantly lower than 13.12% before intervention (χ2 =188.293,P <0.001).While the incidence rate of non -fatal drowning in the control group after intervention was 7.47%, having no significant difference with 6.90% before intervention (χ2 =0.896,P =0.344).And the probability of non -fatal drowning for the intervention group was 0.762 time of the control group.Conclusion The model of integrated drowning interventions,based on the ecological approach and initiated by Ningbo,was proven to be effective and worth popularizing.
