Analysis of neuropsychological development of 24 428 children aged 0-18 months in Guangzhou

Objective To explore the regularity and characteristics of neuropsychological development among children aged 0-18 months in Guangzhou. Method A total of 24 428 children aged 0 to 18 months were recruited in the Child Health Care Unit of Guangdong Women and Children Hospital, from January 1 st, 2015 to December 31 st, 2016. The Chinese Children's Development Scale developed by the Capital Pediatric Research Institute was used to evaluate the five energy areas and the total development quotient of the children.Results The detection rate of total development retardation was 1.7%. The rate of big movement was 13.9%. The rate of fine action was 9.4%. The rate of adaptive development was 12.8%. The rate of language development and social behavior was 9.7% and 7.4%, respectively. The detection rate of total development retardation and developmental retardation in each area in boys were higher than those in girls (1.9% vs. 1.5%, 15.3% vs. 14.1%, 9.6% vs. 9.4%, 13.2% vs. 12.3%, 10.1% vs. 9.2%, 7.4% vs. 7.5%) (P<0.05). The detection rate of total development retardation in children aged 2 months (3.0%), 3 months (2.3%) and 13-18 months (4.7%) was higher than that in other age groups. There were statistically significant differences in big movements, fine movements, adaptability, language development, social behavior and total development among different age groups (P<0.01). Big movement development in 2, 3 months old groups were worse than the other age groups. Fine action in 3 months old group was worse than the other age groups. Adaptive capacity development in 1, 3 months old groups were worse than the other age groups. The language skills, social skills and the total developmental in 13 to 18 months age groups were worse than the other age groups. The total development and each five areas development quotient in boys were lower than in girls (P<0.01).Conclusion The detection rate of total development retardation and retardation in each area in boys were higher than those in girls. Three months and 13 to 18 months are the important time nodes for screening growth retardation. Different months of age need to focus on different areas ofenergy training.
