[Analysis of neuropsychological development characteristics and influencing factors in children with speech sound disorder].

Exploring the neuropsychological developmental characteristics and influencing factors of children with speech disorder. A case-control study was conducted. A total of 395 children diagnosed with speech disorders were selected as speech sound disorder (SSD) group from January 2019 to September 2021 in the speech-speech outpatient department of the Children's Hospital Affiliated to Capital Institute of Pediatrics, and 1 179 healthy children who underwent physical examination in the health department during the same period were selected as the control group. All the children were examined by the "Children's Neuropsychological Behavior Scale 2016 Edition" (Children's Mind Scale 2016 edition). Independent sample test was used to compare the developmental levels of the two groups of children, including total developmental quotient, gross motor, fine motor, adaptive ability, language and social behavior ability. The influential factors of children's speech disorders were analyzed by univariate Chi-square analysis and multivariate logistic regression. There were 395 SSD children, including 296 males and 99 females, 4≤ age ≤6, (4.71±0.76) years. There were 1 179 children in the control group, including 864 males and 315 females, 4≤ age ≤6, (4.64±0.78) years. The mean value of total developmental factors in SSD group was lower than that in control group [(86.45±11.57)/(91.24±8.0), =-7.78, <0.01], and the mean values of total developmental markers in both boys and girls in SSD group were lower than those in control group [(86.00±11.40)/(90.78±7.86), =-6.70, <0.01; (87.82±12.03)/(92.87±8.49), =-3.88, <0.01]. The mean values of gross motor, fine motor, adaptive ability, language ability and social behavior in SSD group were lower than those in control group [(89.76±12.47)/(92.01±10.69), =-3.21, <0.01; (80.62±13.64)/(84.49±11.55), =-5.06, <0.01; (87.92±15.25)/(92.98±12.06), =-6.00, <0.01; (86.48±16.30)/(94.55±12.08), =-9.04, <0.01; (87.02±15.18)/(92.63±12.57), =-6.62, <0.01]; The mean value of fine motor in boys was lower than that in girls in SSD group [(79.80±13.42)/(83.08±14.05), =-2.08, <0.05]. Independent mealtimes. 2 years old (=1.527, 95%: 1.180-1.977, =0.001), delay in adding supplemental food (=1.510, 95%: 1.123-2.029, =0.006), dialect in the home language environment (=1.351, 95%: 1.060-1.723, =0.015) were risk factors for children with speech disorders. Children with speech disorders are more common in boys. The overall development level of SSD children is lower than that of normal children, and the fine motor of SSD boys is lower than that of girls. The incidence of children's speech disorders is related to the addition time of supplementary food, independent meal time and family language environment.
