The Griffiths III community of practitioners requested advice on the reporting of children’s development below the floor of the test, so that individual strengths and needs can be described. This paper reports the third phase of research following an earlier Scoping Review and a wider literature review. To confirm quality control, Phase 3 was conducted in a retrospective manner using the same methodology as the earlier phases but in a reverse direction. Peer reviewer comments and key elements from the Scoping Review and keywords from the publications were tabulated. Data analysis included a change of perspective to that of the child and their individual rights with respect to the literature themes already described in Phase 2. These confirmed that there is little specific guidance in the literature, but that computational advances for homogeneous populations and especially disaggregated data offer some solutions. A greater balance between broad biopsychosocial models and standardised models of assessment should be sought by practitioners together with the use of disaggregated data to highlight issues that pertain to individual subsets of results. This will ensure that the child’s right for their individual strengths and needs to be described together with a plan for management, may be met.展开更多

Therefore, this study was conducted to examine the characteristics of obesity and thinness as assessed by the body fat percentage among children with developmental disorders during certain growth periods. It was also designed to investigate those factors associated with obesity and thinness based on a lifestyle and behavioral questionnaire. The subjects included 260 children from 5 to 18 years old with developmental disorders. The results of the study showed that a decrease in thinness and increase in obesity with ageing exhibited more noticeable trends among those children with mental retardation. The factors associated with obesity in children with developmental disorders were characterized by the dietary content, eating behaviors, and food preferences particular to such children, as well as low physical activity and a family history of obesity. The results of this study suggested the importance of continuous guidance along with family participation in order to improve obesity among children with developmental disorders, while focusing on the characteristics of certain growth periods.展开更多

Methods An EyeLink II was used to record the eye-movement parameters of 32 DD children and 37 non-dyslexic children as they performed the SCWT. The independent samples t-test and repeated measures were used to analyze behavioral and eye-movement parameters. Results Compared to the control group, Chinese DD children presented lower accuracy(F = 8.488), slower response time(F = 25.306), and larger interference effect(t = 2.29); Chinese DD children also exhibited lower frequency of fixations(F = 6.069), greater numbers of saccades(F = 7.914) and fixations(F = 5.272), and shorter mean saccade distance(F = 4.03). All behavioral and eye-movement parameters differed significantly among the three tasks in the SCWT. There was significant interaction between groups and tasks in accuracy(F = 5.844), and marginally significant interaction in response time(F = 3.040). Chinese DD children tended to have lower accuracy and longer response time than the control group in the 'color-word naming' task. Conclusion Compared to non-dyslexic children, Chinese DD children are subject to a stronger interference effect. When performing the SCWT, Chinese DD children exhibit abnormal eye-movement patterns, namely shorter mean saccade distance, lower frequency of fixations, and more fixations and saccades. These abnormal eye movements may be relatively stable oculomotor patterns of DD children performing visual processing, and not influenced by impaired interference effect.展开更多

Furthermore, obese children reportedly go on to be obese in adulthood. Obesity is likely to cause lifestyle-related diseases not only in able-bodied individuals but also in disabled children. Specific cognitive behavior observed in disabled children often hinders the provision of lifestyle guidance, such as nutritional and physical exercise instructions. To prevent such situations, early identification of obesity is required to improve lifestyle habits through diet and exercise in disabled children. This study included 285 children with developmental disorders. To assess a childhood obesity index, three obesity-related parameters were compared: the degree of obesity in school health, which has been used to evaluate the health of school children in Japan;abdominal circumference, which is useful for predicting visceral fat obesity;and the waist-to-height ratio (WHtR), which reflects visceral fat and physique. The abdominal circumference was significantly dependent on age. The degree of obesity and WHtR did not show a significant association with age. WHtR was significantly associated with the degree of obesity in school health. The WHtR is easily calculated as compared to the degree of index in school health which needs rather complicated calculations depending on age and age-specific coefficients. The study findings suggest that WHtR might be an easy-to-use obesity index comparable to the degree of obesity in school health in children with developmental disorders.展开更多

Methods: We performed a secondary analysis on a prospective, observational age-matched, 1:2 case-control study of children aged 3 - 10 years who were sedated for brain MRI. AP airway diameters were determined at the level of soft palate (airway_SP) and tongue (airway_T) from midline sagittal images by a single blinded radiologist. Results: Airway diameter was evaluated in 134 controls (C) and 68 cases (D). There was no difference in the overall adverse events (D: 30% C: 32.9%;p = 0.7) as well as hypoxia (D: 10%;C: 9.3%, p = 0.9). There was no significant difference in mean airway_T (D: 10.62 ± 3.48 vs. C: 10.38 ± 3.47;p = 0.64) and airway_SP diameter (D: 4.59 ± 2.36 vs. C: 5.17 ± 3.9;p = 0.14) between the two groups. There was no significant difference in airway_T and airway_SP diameters amongst those who experienced and those who did not experience hypoxia in cases. Amongst controls however, the airway_SP was smaller in those who experienced hypoxia compared to those who did not experience hypoxia. Conclusions: There was no difference in the AP airway_T and airway_SP diameter during sedation using static MRI images in children with and without developmental disabilities. Changes in airway_SP was associated with hypoxia amongst controls in our study cohort.展开更多

Purpose: To determine the prevalence, socio-demographic profile, aetiologies, and the clinical presentation of developmental delay in children less than 6-year-old at the child neurology unit in a university-affiliated hospital in Yaounde. Materials and methods: It was a crosssectional descriptive study carried out in Yaounde Gynaeco-Obstetric and Paediatric Hospital (Cameroon) from August to December 2012. Children aged between 5 - 72 months with a developmental quotient less than 70 were enrolled. Developmental delay (DD) was diagnosed and classified using the Denver developmental screening test (DDST). Data concerning the child (age, gender, severity of DD), the mother (age, age at conception, educational level, marital status), history of pregnancy and delivery, perinatal and postnatal events, results of para-clinical explorations (EEG, CT-scan, genetic tests), the severity of DD and the probable or demonstrate cause of DD were recorded on a standardized questionnaire. The chisquare test was used to compare variables. Results: During the study period, 2171 children aged 5 - 72 months consulted the paediatric department of the hospital, 296 were examined at the child neurology unit of which 153 had a developmental quotient less than 70, giving a hospital prevalence of 7.0% and a prevalence of 51.7% at the child neurology unit. The mean age was 26.6 ± 18.0 months and there were 56% males. The main reason for consulting was tonus disorder (43.8%) and the developmental area of parental concern was the motor domain (90.2%). Regarding the clinical presentation, 75.2% of our population were children with cerebral palsy. DD was severe, mild, moderate and profound respectively in 14.2%, 13.5%, 12.2%, and 11.1%. Gross DD represented 90.2% of all DD children. The causes of DD were hypoxic-ischemic encephalopathy (41.8%), epilepsy (13.7%), sequelae of meningitis (6.5%), sequelae of kernicterus (6.5%), and infectious embryofoetopathies (5.2%). Conclusion: Developmental delay is frequent in paediatric neurology, with perinatal disorders being the leading aetiologies in Cameroon. Prevention of perinatal hypoxic-ischemic encephalopathy risk factors needs to be reinforced.展开更多

文摘Objective: Our study objective was to compare the anteroposterior (AP) oropharyngeal airway diameter measured using static MRI images in children with and without developmental disabilities during sedation. Methods: We performed a secondary analysis on a prospective, observational age-matched, 1:2 case-control study of children aged 3 - 10 years who were sedated for brain MRI. AP airway diameters were determined at the level of soft palate (airway_SP) and tongue (airway_T) from midline sagittal images by a single blinded radiologist. Results: Airway diameter was evaluated in 134 controls (C) and 68 cases (D). There was no difference in the overall adverse events (D: 30% C: 32.9%;p = 0.7) as well as hypoxia (D: 10%;C: 9.3%, p = 0.9). There was no significant difference in mean airway_T (D: 10.62 ± 3.48 vs. C: 10.38 ± 3.47;p = 0.64) and airway_SP diameter (D: 4.59 ± 2.36 vs. C: 5.17 ± 3.9;p = 0.14) between the two groups. There was no significant difference in airway_T and airway_SP diameters amongst those who experienced and those who did not experience hypoxia in cases. Amongst controls however, the airway_SP was smaller in those who experienced hypoxia compared to those who did not experience hypoxia. Conclusions: There was no difference in the AP airway_T and airway_SP diameter during sedation using static MRI images in children with and without developmental disabilities. Changes in airway_SP was associated with hypoxia amongst controls in our study cohort.

Conclusion: Developmental delay is frequent in paediatric neurology, with perinatal disorders being the leading aetiologies in Cameroon. Prevention of perinatal hypoxic-ischemic encephalopathy risk factors needs to be reinforced.

文摘Does enrolling children aged 0-3 in early childhood education(ECE)classes continuously empower their learning and development after entering kindergarten?Based on the tracking survey data of 664 children aged 3-6 in 2017 and 367 children aged 3-6 in 2018,this study uses Propensity Score Matching to analyze this issue.The findings reveal that children’s family socioeconomic status is a key factor influencing their participation in ECE classes.The baseline data show that participation in ECE classes does not significantly improve children’s learning and development.However,the follow-up data show that participation in ECE classes plays a significant negative role in motor development for children moving to their second year of kindergarten,but subsequently plays a positive role in language development,health,and safety for those entering their third year of kindergarten.Overall,participation in ECE classes plays no continuous positive role in children’s learning and development after they enter kindergarten.Based on these findings,it is suggested that parents should respect the natural laws of child development instead of blindly following the trend of attending ECE classes,and high-quality parental companionship is crucial.The Chinese government is supposed to implement policies such as“double reduction”to regulate ECE institutions that fail to operate in good faith.
