ABSTRACT
Objective@#To explore the relationship between maternal emotional symptoms and emotional and behavioral problems (EBPs) of preschool offspring, and to provide reference for prevention and intervention of emotional and behavior problems in preschool children.@*Methods@#A total of 4 100 preschool children aged 3-6 in Fuyang City were enrolled by stratified cluster sampling method in June 2021. The Strengths and Difficulties Questionnaire (SDQ) and Depression Anxiety and Stress Scale (DASS-21) were used to investigate preschool children s EBPs and maternal emotional symptoms, respectively.@*Results@#The detection rates of preschool children s emotional symptoms, conduct problems, hyperactivity, peer interaction problems, prosocial behavior and difficulty scores were 15.7%, 17.4%, 20.0%, 32.3%, 15.1% and 15.8%, respectively. The detection rates of mother s depression, anxiety and stress symptoms were 7.9%, 12.7% and 4.8%, respectively. Multivariate Logistic regression analysis showed that, compared with children of mothers with no depression, anxiety and stress symptoms, offspring of mothers reported depression, anxiety and stress symptoms had significantly higher risks of emotional symptoms, conduct problems, hyperactivity, peer problems and total difficulties ( OR=1.76-6.35, P <0.01). Maternal emotional symptoms had the most significant effect on children s emotional symptoms, and there was no significant correlation between maternal stress symptoms and children s prosocial behavior ( OR=1.40, P >0.05). There was no significant gender difference in the relationship between maternal emotional symptoms and children s emotional and behavioral problems ( ROR=0.73-1.07, P >0.05). For only children whose mothers reported stress symptoms showed a higher risk of emotional and behavior problems than non singleton children ( ROR=2.03, P <0.05).@*Conclusion@#Maternal emotional symptoms are related to preschool children s emotional and behavioral problems. Early identification and intervention of mother s negative emotional symptoms, are beneficial to the prevention of preschool children s emotional and behavioral problems.
ABSTRACT
BACKGROUND:Human has a high level heritability in physical performance. With the development of technology and test method in molecular biology, the researchers of sport science are concerned with the influence of gene variation on the elite athlete performance. They begin to know the important value of gene on predicting the physical performance. OBJECTIVE:To review the research results in the field of gene polymorphisms and elite athlete performance and to expatiate the problems in these researches, thereby offering some proposals. METHODS:A computer-based online research of PubMed and CNKI databases was performed to col ect articles published from 1998 to 2013 with the key words“elite athlete performance, gene polymorphisms, endurance, power, training response”in Chinese and English. There were 150 articles after the initial survey. A total of 80 articles were included according inclusion and exclusion criteria. RESULTS AND CONCLUSION:The researches of this field are mainly focused on the three aspects:elite endurance performance, elite power performance, and training response, which are associated with gene polymorphisms. The main genes related to elite endurance performance are ACE, mtDNA, PPAR, ADR, GNB3, NRF2, etc. The main genes related to elite power performance are ACTN3, ACE, GDF-8, IL-6, HIF-1, etc. The main genes related to training response are HBB, TFAM, NRF2, AR, FECH, etc. Several gaps in the current researches have been identified including smal sample size of most athletic cohorts, lack of corroboration with replication cohorts of different ethnic backgrounds. The numerous research findings can be applied to the gene selection of athletes by creating some kinds of algorithms and models.
