Background: Many community and hospital based studies have found high prevalence of childhood psychiatric morbidity in the community and hospital. However, it has been noticed that few children are presented to hospital by parents with complaints related to psychological or emotional disturbances. This may be due to stigma and discrimination attached to mental illness including those of children. Aim: This part of the study set out to assess the attitudes of parents to childhood psychiatric disorders. It also set out to reveal what factors were associated with attitude and predictors of positive or negative attitude. Methodology: A cross-sectional study was carried out where parents were interviewed and the sociodemographic features of the child, parents and family were elicited. The study was carried out at Murtala Muhammad Specialist, hospital, Kano, Nigeria within a three months period. The child was assessed for psychological disorder with the Reporting Questionnaire for children. Parent’s attitude was assessed with a modified community attitude towards the mentally ill scale, (CAMI). Result: A total of two hundred and three subjects (203) were involved in the study. Most (78.3%) parents had negative attitude to childhood psychiatric disorders while only (13.8%) had positive attitude. Parents who classified a child as having a psychological component to their illness were more likely to exhibit positive than negative attitude (83.3% vs. 16.7%, X2 = 22.75, d.f = 1, p = 0.0002). Those with positive attitude were more likely to be mothers than fathers (71.4% vs. 28.6%;X2 = 4.78, d.f = 1, p = 0.04). Those with a family history of psychiatric illness were more likely to exhibit positive than negative attitude. (58.3% vs 41.7%;X2 = 18.94, d.f = 1, p = 0.0003). A child’s father being of lower social class predicted positive attitude. No variable predicted negative attitude. Conclusion: Most parents had negative attitude to psychiatric disorders in children. The study advocated health education and enlightenment programmes to enhance mental health literacy for parents so that they could develop a more positive attitude to psychiatric disorders including childhood psychiatric disorders which will lead to reduction in childhood psychiatric disorders and later adversities. 展开更多

Nowadays, creativity is the main need for continuing the life in the various aspects of society, especially education. Parenting attitude of youth fostering as an important factor can be effect on creativity, because youth are dependent to parents and they are as power recourse for youth. Youth are in interaction with parents and parents can be ready appropriate filed in home and family to efflorescence their youth’s creativity. The present study undertakes to provide a descriptive and correlative analysis on the relationship between youth fostering and student creativity. Parenting attitudes (including domination, high dependency, and negligence) and creativity (including fluency, originality, flexibility and elaboration) are taken as independent and dependent variables, respectively. To test the hypotheses, information collected from three questionnaires was analyzed: 1) multiple choice paper and pencil test for measuring Torrance creativity (1973), 2) parent attitude survey (PAS) of Drews and Teahen (1957), and 3) evaluation of students’ creativity by masters. Statistical population of the study includes all students of Urmia Medical Sciences University (209 males and 218 females) and their parents. Data analysis was performed by SPSS software using descriptive and inferential statistical methods. Results indicate no significant relationship between student creativity and parents attitude on youth fostering (r = 0.20) and parents put more emphasis on educational success than creativity. Also, female students had better performance than males in terms of creativity. 展开更多

Purpose: We aimed to examine the longitudinal associations between parents' and youth's participation in physical activity(PA).Methods-: One hundred and ninety youth cuompleted self-admitiistered questionnaires 3 times per year from 2011 to 2015, and their parents completed an interviewer-administered questionnaire during a telephone interview once in2011-2012. Data on youth's and parents' activities were classified as interdependent or coactive/imdependent.Results: Youth with one or both parents who participated in interdependent activities were more likely to maintain participation in interdependent activities(hazard ratio(HR) = 3.63: 95% confidence interval(CI) = 1.30-10.17). Youth's sustained participation in coactive/independent activities was not associated with parents' participation in coactive/independent activities(HR= 0.97; 95%CI=0.46-2.06).Conclusion: Longitudinal associations between parents' and youth's participation in PA differed across type of PA. Encouraging parents' participation in interdependent activities may promote sustained participation in interdependent activities in youth. 展开更多

Background:Determining the prevalence of doping in sport might be useful for anti-doping authorities to gauge the effectiveness of anti-doping policies implemented to prevent positive attitudes toward doping.Using questionnaires and personal interviews,previous investigations have found that the prevalence of doping might be different among different sports disciplines;however,there is no sport-specific information about the proportion of adverse and atypical findings(AAF) in samples used for doping control.The aim of the present investigation was to assess the differences in the frequency of adverse analytical and atypical findings among sports using the data made available by the World Anti-Doping Agency.Methods:The data included in this investigation were gathered from the Testing Figures Reports made available annually from 2003 to 2015 by the World Anti-Doping Agency.These Testing Figures Reports include information about the number of samples analyzed,the number of AAFs reported,and the most commonly found drugs in the urine and blood samples analyzed.A total of 1,347,213 samples were analyzed from the individual sports selected for this investigation,and 698,371 samples were analyzed for disciplines catalogued as team sports.Results:In individual sports,the highest proportions of AAF were 3.3%±1.0% in cycling,3.0%±0.6% in weightlifting,and 2.9%±0.6% in boxing.In team sports,the highest proportions of AAF were 2.2%±0.5% in ice hockey,2.0%±0.5% in rugby,and 2.0%±0.5% in basketball.Gymnastics and skating had the lowest proportions at(≤1.0%) for individual sports,and field hockey,volleyball and football had the lowest proportions for team sports(≤1.4%).Conclusion:As suggested by the analysis,the incidence of AAF was not uniform across all sports disciplines,with the different proportions pointing to an uneven use of banned substances depending on the sport.This information might be useful for increasing the strength and efficacy of anti-doping policies in those sports with the highest prevalence in the use of banned substances. 展开更多

Background: One efficient way to increase physical activity is through sport participation because participation in sport activities inherently includes many enjoyable aspects, such as social interaction, competition, personal challenge, and goal achievement. The main purpose of this study was to investigate the longitudinal effect of parental support during adolescence on the trajectory of sport participation from adolescence through young adulthood.Methods: The data used in this study came from the National Longitudinal Study of Adolescent to Adult Health(Add Health). It is a 4-wave longitudinal study that followed up a nationally representative sample of middle and high school students in the US. A series of multilevel logistic regression models were used to examine the effect of parental support at Wave 1 on the trajectory of sport participation from Wave 1 to Wave 4.Results: The effect of parental support during adolescence on participants' sport participation lasted until they become young adults(Wave 3)(p < 0.001). Among the male participants, parental support at Wave 1 was a significant predictor for sport participation at Waves 1, 2, and 3(p < 0.001). However, a significant effect of parental support at Wave 1 on sport participation in early young adulthood(Wave 3) becomes insignificant when adjusting for self-esteem and depression. Among the female participants, parental support at Wave 1 was a significant predictor for sport participation at Waves 1, 2, and 3(p < 0.01) even after depression and self-esteem were introduced into the model. That is to say, unlike male participants, parental support during adolescence has an independent effect on sport participation from adolescence(Wave 1) through early young adulthood(Wave 3) over and above the effects of depression and self-esteem in female participants.Conclusion: The results of this study contributed to the literature by providing important information on the longitudinal effect of parental support during adolescence on the trajectory of sport participation from adolescence through young adulthood using a nationally representative sample of participants transitioning from adolescence to young adulthood. 展开更多

Background:There is an increasing trend on the practices of parental self-medication with antibiotics(PSMA)around world,accelerating the antibiotic abuse.This study aims to examine the nationality differences in the practices of PSMA and knowledge,attitudes and practices(KAP)toward antibiotic use,and understand the practices of PSMA among parents of various nationalities in China.Methods:A cross-sectional study based on a structured questionnaire survey was conducted in Xi’an,Shaanxi Province,China,from September 2018 to October 2018.A total of 299 respondents participated in.The practices of PSMA(a dichotomous variable)and KAP toward antibiotic use(a continuous variable)served as dependent variables.Participant’s nationality was regarded as the independent variable.Binary logistic regression and ordinary least square regression were employed to examine the association between parent’s nationality and the practices of PSMA,and KAP toward antibiotic use,respectively.Results:121(40.88%)Chinese,100(33.76%)other Asians and 75(25.34%)Occidentals were included in final analysis,with a sample size of 296.Chinese were more likely to practice PSMA(OR=7.070;95%CI 1.315,38.01),with worse knowledge(Coef.=−0.549;95%CI−1.021,−0.078),attitudes(Coef.=−3.069;95%CI−4.182,−1.956)and practices(Coef.=−1.976;95%CI−3.162,−0.790)toward antibiotic use,compared to their Occidental counterparts.The main reasons for the practices of PSMA were enough previous medication experience(80.49%)and same ailments with no need to see a doctor(39.02%),with common symptoms such as fever(60.98%)and cough(58.54%).Purchasing antibiotics at pharmacies(92.08%)and using leftover antibiotics(26.83%)were usual approaches.Conclusions:The study highlights the gaps in the practices of PSMA and KAP toward antibiotic use among parents of different nationalities.The access to obtain antibiotics from pharmacies reflects the pharmacists’unaware of laws on prescription of antibiotics,fierce competition in the pharmacy market,and the government’s lax supervision in China.It suggests the need to improve pharmacists’training,enforce current legislations on pharmacy market regarding the sale of antibiotics,and provide practical and effective educational interventions for residents about antibiotic use. 展开更多

Purpose: The objective of this study was to examine the associations between parental support for physical activity(PA) and levels of moderate-to-vigorous physical activity(MVPA) among Chinese school children.Methods: Study participants were 81,857 school-aged children(aged 9–17 years; mean age = 13 years; 49.0% boys) and their parents or guardians who took part in the 2016 Physical Activity and Fitness in China—The Youth Study project. The independent variables included various forms of parental support for PA ascertained through a survey completed by parents or guardians. The dependent variable was the children's average MVPA in minutes per day by self-report. Structure equation modeling was used to examine the associations between parental support for PA and children's MVPA minutes.Results: The overall mean for MVPA participation time for the child participants was 48.82 ± 28.71 min/day. Significant associations between various forms of parental support and MVPA among children were found. Parental encouragement, accompanying, financial support, involvement,and role modeling for PA were positively associated with a high level of student MVPA participation. Parental PA knowledge-sharing was not associated with MVPA. The patterns of the associations were similar across sex, residence locale(i.e., urban and rural), and school grades(primary,junior middle, and junior high schools).Conclusion: Findings from this study suggest that, among Chinese school children, parental support for PA is important in promoting and facilitating children's participation in MVPA. 展开更多
