Objective To explore the effect of early home nurture environment on children's developmental quotients(DQ) and social emotional development,and provide basis for children's early development promotion. Methods The "Child Home Nurture Environment Questionnaire" was performed at 3 months and 12 months with 188 infant-toddlers randomly sampled from Jinan city,and the "12~36 month Infant-toddler Social and Emotional Assessment Scale" and the "Children's Diagnostic Development Scale" were carried out at 2 years old.The relationship between home nurture environments and development level and social emotional development were analyzed. Results There were significantly positive correlations between perception/cognition,interpersonal interaction/feeding factors,total score of child nurture environment at 3 months,also language/cognition at 12 months and DQ as well as most function domains except gross motor at 2 years old;There were significantly positive correlations between social adaptation/self-care factors at 12 months and language development at 2 years old;And there were negative correlation between the total score of home nurture environment at 3 months and the externalizing,internalizing and deregulation domains at 2 years old.The social adaptation/self-care,neglect/punishment factors,total score of home nurture environment at 12 months had significantly negative correlation with externalizing,deregulation domains,and all factors of home nurture environment had significantly positive correlation with competence domains. Conclusions Early home nurture environment has direct effects on children's early development and the social emotional development.Children's early development and the social emotional development should be promoted by improving home nurture environment as early as possible.
