OBJECTIVES: To investigate the neurodevelopmental characteristics of children with autism spectrum disorder (ASD), analyze the correlation between neurodevelopmental indicators and cerebral blood flow (CBF), and explore the potential mechanisms of neurodevelopment in ASD children. METHODS: A retrospective study was conducted on 145 children aged 2-6 years with newly-diagnosed ASD. Scores from the Gesell Developmental Diagnosis Scale and the Autism Behavior Checklist (ABC) and CBF results were collected to compare gender differences in the development of children with ASD and analyze the correlation between CBF and neurodevelopmental indicators. RESULTS: Fine motor and personal-social development quotient in boys with ASD were lower than those in girls with ASD (P<0.05). Gross motor development quotient in ASD children was negatively correlated with CBF in the left frontal lobe (r=-0.200, P=0.016), right frontal lobe (r=-0.279, P=0.001), left parietal lobe (r=-0.208, P=0.012), and right parietal lobe (r=-0.187, P=0.025). The total ABC score was positively correlated with CBF in the left amygdala (r=0.295, P<0.001). CONCLUSIONS: Early intervention training should pay attention to gender and developmental structural characteristics for precise intervention in ASD children. CBF has the potential to become a biological marker for assessing the severity of ASD.

[Parenting skills situation and need assessment among parents of primary school pupils].

OBJECTIVE: To investigate parenting skills and need among parents of primary school pupils and to explore influencing factors. METHODS: A total of 1 394 parents of rural and urban primary school pupils were recruited by multistage stratified random clustered sampling method. They were asked to complete a self-report questionnaire regarding demographic and socioeconomic backgrounds, parenting scale, parenting need assessment, parent-to-child interaction attitudes, social support, physical/mental maltreatment experiences in childhood and so forth. RESULTS: Apart from TV/film/broadcasting, rural parents' utilization of other parenting deliveries was less than that of urban parents. Urban and rural parents both had high needs for parenting skills. Parents' physical/mental maltreatment experiences in childhood were risk factors for dysfunctional parenting. Positive parent-to-child interaction attitudes and high social support were protective factors against dysfunctional parenting. Mothers, parents of boys, middle/low family incomes, and parents with positive parent-to-child interaction attitudes had higher demands for parenting skills. CONCLUSION: We should make full use of mass media, interpersonal communication to meet the needs of parenting for parents, especially rural parents. More attention should be paid to parents with childhood maltreatment experiences, low social support and less positive parent-to-child interaction attitudes.

[Investigation on dietary nutrients among rural stranded children of 2-7 year olds in china].

OBJECTIVE: To understand the dietary nutrients among rural stranded children. METHODS: 2551 children aged 2 to 7, including 1278 stranded children in the rural areas and another 127 children served as controls were selected, using multistage stratified cluster random sampling. Dietary survey was performed with three-day weighing dietary method and questionnaire on food intake. Data on diet were analyzed and evaluated by the Dietary Reference Intakes (DRIs) recommend by Chinese Nutrition Society, to evaluate the levels on energy and nutrient intake among stranded children in the rural areas. RESULTS: The dietary pattern among rural stranded children mainly consisted of grains and vegetables, but the intakes of animal products, fruits, and snacks were significantly less than in the control group. The intakes of three major energy-producing nutrients were below the recommend nutrient intake. Minerals as calcium, zinc, selenium, kalium and vitamins as vitamin A, B1, B2 were insufficient. Most of the rural stranded children took nutrients insufficiently, with 50% lack of adequate energy and 80% of protein, 90% of minerals (calcium, zinc etc.) and vitamins (vitamin BI and vitamin B2 etc.). Sources from high quality protein was insufficient, only consisting 35% of the total protein, but overabundant (over 64%) from the plants. The intake of plant-sources iron was overabundant, accounted for 87%. CONCLUSION: The dietary pattern was unsatisfactory with insufficient intake of energy-sources proteins and some nutrients. The sources of energy, protein, and iron were mostly obtained from underbalanced foods. It is necessary to improve the dietary nutrients status among rural stranded children aged 2-7 years.
