Abstract: Objective
To learn about the level and the rules of neuropsychological development of infants and children aged 0 to 24 months.
Methods
The Neuropsychological Development Scale for Children Aged 0 to 6 Years was used to make development quotient(DQ) testing(gross motor, fine motor, adaptability, language and social behavior), in order to study the main risk factors that influence the neuropsychological development of infants and children.
Results
The total growth retardation rate was 2.15% in the infants and children aged 0 to 24 months. The multiple linear regression analysis showed that the following factors influenced the DQ, which included gender, premature delivery, body mass at birth, body length at birth, age(months) at physical examination and increase in body mass and body length(P<0.05). The interaction between body mass at birth and premature delivery, body mass at birth and body length at birth, age(month) at physical examination and increase in body mass, and age(month) at examination and increase in body length also had influence on DQ(P<0.05). The analysis of the influencing degree of independent variables revealed that age(month), increase in height, age (month) and height, gender and increase in body mass had greater influence on DQ.
ConclusionThe early stage nutrition in infants and children has significant influence on the development quotient. The healthcare work for children must pay great attention to the nutritional intervention at the early development in infants and children. When analyzing the factors influencing DQ, the interactions between the child's growth and development and those factors must be taken into account.
