Abstract: Objective To analyze the developmental problems of 0~6 years old children by Gesell development scale assessment, analyze the distribution of developmental lag in children of different months and genders, and provide evidence for early effective intervention. Methods A total of 409 children with developmental problems aged 0 to 6 years old screened by Fangshan District Community Health Service Center from 2019 to 2023 were calculated using the Software for Evaluation of Developmental Diagnosis for children aged 0 to 6 years old, published in March 2009 by Beijing Maternal and Child Health Hospital. The content of the test included five areas of adaptability, gross motor, fine motor, language and personal-social ability, and the developmental lag of each area was analyzed statistically. Results Children of 3 to 11 months of age, 12 to 23 months of age, 24 to 35 months of age, 36 to 72 months of age had higher rates of adaptive and personal-social developmental lag than normal, fine motor and gross motor lag than normal, and language lag was lower than normal, with statistical significance (P<0.05). The fine motor development of boys aged 12 to 23 months and 36 to 72 months was inferior, and the individual-social development of boys aged 24 to 35 months and 36 to 72 months was higher than that of girls. The fine motor development lag of girls aged 24 to 35 months was higher than that of boys, and the difference was statistically significant (P<0.05). The proportion of gross motor, fine motor and personal-social developmental retardation at 3 to 11 months, 12 to 23 months, 24 to 35 months and 36 to 72 months was higher than that of moderate or above. The proportion of moderate and above retarded language development increased with age, and was higher than that of mild language development at 36 to 72 months. Conclusion Children aged 3 to 11 months have higher than normal rates of adaptive, individual-social, fine motor and gross motor retardation, but lower than normal rates of language retardation. With age, fine motor and gross motor delay decrease and speech delay increases. In terms of sex, boys lag behind in fine motor development at 12 to 23 months and 36 to 72 months and girls lag behind in personal-social development at 24 to 35 months and 36 to 72 months. Girls lag behind in fine motor development at 24 to 35 months than boys. The degree of developmental lag: mild developmental delay was more than moderate or above in all age groups, and the language development delay increased with age, and the proportion of moderate or above in 36~72 months increased significantly.
