RESUMEN
Objective:To explore the relationship between executive function and gait in cases of mild amnestic cognitive impairment (aMCI).Methods:Twenty aMCI hospital patients formed an observation group, while 20 healthy counterparts were the control group. Both groups underwent the Tinetti test, followed by the " normal walking" single-task test and the " normal walking + Go/No-go" dual-task test. The pace, step width, stride length, Go/No-go task response time and accuracy rate were recorded.Results:In the single-task test, there was no significant difference in pace or stride width between the two groups, but the average stride length of the observation group (1.11±0.04)cm was significantly shorter than that of the control group. However, in the dual-task test, the average pace time (0.96±0.08)sec and stride length (1.02±0.06)cm of the observation group were significantly smaller than the control group′s averages, while their step width (0.11±0.02)cm was significantly wider. There was no significant difference between the two groups in the response time in a single (Go/No-go) task, but in the dual-task test, the observation group′s average time was significantly longer than the control group′s and the accuracy was significantly poorer. Both the error rate and the non-response rate were significantly higher than among the control group.Conclusions:Mild amnestic cognitive impairment reduces stride length and pace when walking and impairs executive function.
RESUMEN
Objective To investigate the role of different parenting styles plays in conduct problems of 3-years-old preschool children.Methods Participants were from 148 preschools in Longhua Shenzhen,China.A structured questionnaire covering family demographic characteristics,Conners' Parent Symptom Questionnaire and Egna Minnen Betraffande Uppfostran-Parents (EMBU-P) were conducted among primary caregivers of each child.There were 9289 valid participants in the analysis and logistic regression was used to assess the relationship between three dimensions of parenting (rejection,emotional warmth and control/overprotection) and conduct problems.Results After allowing for certain confounders,parental rejection (OR =1.17,P＜0.01) and control/overprotection (OR =1.03,P＜0.01) was positively associated with conduct problems and emotional warmth was negatively related to conduct problems (OR=0.98,P＜0.01).Stratified analysis showed a significant relationship between conduct problems and both parents' rejection (OR father=1.16,P＜0.01;OR motber=1.17,P＜0.01),father's emotional warmth (OR=0.96,P＜0.01) and mother's control/overprotection (OR=1.04,P＜0.01).This relationship did not vary between boys and girls and between single and not single children.Conclusion Influence of parenting should be taken into consideration in the prevention and intervention of conduct problems.
RESUMEN
Objective To explore the interaction between passive smoking and folic acid supplement during pregnancy on children autism spectrum disorder (ASD) behaviors.Methods Children aged about 3 years were enrolled at kindergarten entrance in Longhua district of Shenzhen in 2014.Self-administered questionnaires were completed by their primary caregivers and the information about children' s age,gender,history of preterm birth and low birth weight,parents' education level,parents' reproductive age and family income were collected.The children ASD behaviors were assessed with Autism Behavior Checklist (ABC).According to the cut point of ABC,the children were divided into normal group with score less than 31,sub-clinical group with score ranging from 31 to 61 and suspect clinical group with score no less than 62.After controlling for potential confounders,multivariate logistic regression analysis was performed to evaluate the main effects and the interaction between passive smoking and folic acid supplement during pregnancy on children ASD behaviors.Results Maternal passive smoking during pregnancy was significantly associated with children ASD behaviors (sub-clinical group:OR=1.48;suspect clinical group:OR=2.85),and maternal folic acid supplement during pregnancy was not related to children ASD behaviors (sub-clinical group:OR=1.04;suspect clinical group:OR=0.75).Stratified analysis showed that folic acid supplement during pregnancy was negatively associated with children ASD behaviors (suspect clinical group:OR=0.30) among children without mothers' passive smoking during pregnancy,and that mothers' passive smoking during pregnancy was positively associated with children ASD behaviors (sub-clinical group:OR=1.52;suspect clinical group:OR=4.45) among the children whose mothers had folic acid supplement during pregnancy.Furthermore,an interaction effect on children ASD behaviors was found between passive smoking and folic acid supplement during pregnancy (suspect clinical group:OR=5.30).Conclusion Passive smoking and folic acid supplement during pregnancy were related to children ASD behaviors and had an interaction on children ASD behaviors.
