Objective To understand the trends and characteristics of injuries among preschool children in a community of Shanghai,and to evaluate the effectiveness of community-based injury prevention and intervention.Methods Data on injuries among preschool children from 9 kindergartens of a community in Shanghai in 2011,2014 and 2016 were obtained from questionnaire survey to analyze injury incidence rates,trends and the characteristics.Results The overall-and boy-specific injury prevalence was 12.4%,8.6%,and 7.4% and boys'injury incidence rates 14.4%,9.1%,and 6.2%,in 2011,2014 and 2016,respectively.However,no similar trend was found among girls (10.6%,8.1%,and 8.8%,respectively).Compared with 2011,the overall injury risks of 2014 and 2016 decreased(OR=0.603,95%CI=0.471-0.772;OR=0.556,95%CI=0.430-0.71),and boys' injury risks decreased(OR=0.517,95%CI=0.368-0.726;OR=0.380,95%CI=0.261-0.554).Most of the injuries occurred in the afternoon and evening.Girls' injury incidence rate in the afternoon was 2.18%,2.41% and 2.92% respectively,and increased by year.Injuries occurred mainly at home.Injury occurred at home among boys was 5.17%,3.16% and 2.09% respectively,and was 2.45%,3.01% and 3.40% for girls.The top two types of injury were falling and colliding.Conclusion Community-based injury prevention and intervention decrease preschool child injury.A general declining trend is found in overall injury prevalence with significant gender differences.Safety education towards guardians should be improved,especially among girls.
