Objective To explore the influencing factors for children with language development delay,in order to provide reference for preventing language development delay. Methods A case-control study was conducted on 248 children aged 1 to 6 years by questionnaire survey from October 2016 to June 2017,including 124 cases with language development delay and 124 normal control. The correlations between social demographic data,family environment,birth status,behavior and language development were analyzed.The S-S linguistic retardation assessment was adopted. Results Seven risk factors for language development in children were identified by Logistic stepwise regression analysis,including skip-generation raising(OR=3.391,95% CI:1.654-6.951),maternal education under senior high school(OR=5.186,95% CI:2.245-11.981),teaching with audio electronic toys or reading(OR=2.070,95% CI:1.122-3.817),screen time over 1 h/d(watching TV OR=2.305,95% CI:1.245-4.267;mobile phone and IPAD OR=3.246,95%CI:1.277-8.248),high-risk factors at birth(OR=2.253,95% CI:1.084-4.680) and during pregnancy(OR=2.575,95% CI:1.129-5.873). Conclusions The influence of family environment,rearing pattern and being exposed to electronic screen on children's language development should not be ignored.Avoiding risk factors and providing favorable language environment and scientific parenting views may help to prevent language delay in children.
