This article reviews recent research evidence, largely from systematic reviews, on a number of aspects of childhood obesity: its definition and prevalence; consequences; causes and prevention. The basis of the body mass index (BMI) as a means of defining obesity in children and adolescents is discussed: a high BMI for age constitutes obesity. In recent years the prevalence of obesity has increased dramatically across most of the world, and in the UK obesity prevalence is high and continuing to increase. Despite a widespread perception that obesity in childhood or adolescence is a cosmetic issue, the research evidence shows that it does matter to physical and psychological health and that there are adverse health risks for both the obese child and the adult who was obese as a child. Few interventions aimed at preventing or treating childhood obesity have been successful. There is an urgent need for more research on better strategies that will enable children and adolescents to make long‐term changes to their dietary and physical activity behaviour in order to prevent obesity. 相似文献

The present study was designed to test the effectiveness of using a biographical inventory as an alternative to a traditional personality inventory in measuring the five factor model of personality. A combination of empirical and rational strategies were incorporated in the development and scoring of the biodata items. All (N = 383) participants completed the newly developed Biodata Inventory and the NEO-Five Factor Inventory. Confirmatory factor analysis was performed to examine the goodness of fit of the five factor structure from the respondents’ data. All participants completed a letter cancellation task, reported grade point averages, and SAT scores. Predictive validity was assessed for both instruments’ scores. Results indicate that the five factor model fit the data from the biodata and personality inventories. Predictive validities of both inventories’ scores were consistent with many other research results. The relationship of the Conscientiousness biodata scores to grade point average and task completion performance were statistically significant. 相似文献

AbstractIn this article the interest is on finding the fiducial distribution of the parameter, when the probability distribution belongs to the power series family, as in Johnson et al. (1992). Recently in Nájera and O’Reilly (2017) an argument is given to obtain a unique fiducial in the Bernoulli case. An attempt is made here to define some sort of invariance in a power series distribution so that, as was done in the Bernoulli case, one may find a unique invariant fiducial for the parameter. The Bernoulli case is reviewed in detail and the Poisson and negative binomial cases are addressed. 相似文献

For testing the fit of a discrete distribution, use of the probability generating function and its empirical counterpart has been suggested in Koeherlakota and Kocherlakota (1986). In the present paper, a particular functional of the corresponding empirical probability generating function process is proposed as a measure to test the discrepancy between the evidence and the hypothesis. The asymptotic behavior of the empirical probability generating function when a parameter is estimated is obtained, The study is exemplified for the Poisson case only but the procedure can be extended to other discrete distributions. 相似文献

A need for modeling abnormal behavior on a comprehensive, systematic basis exists. Computer modeling and simulation tools offer especially good opportunities to establish such a program of studies. Issues concern deciding which modeling tools to use, how to relate models to behavioral data, what level of modeling to employ, and how to articulate theory to facilitate such modeling. Four levels or types of modeling, two qualitative and two quantitative, are identified. Their properties are examined and interrelated to include illustrative applications to the study of abnormal behavior, with an emphasis on schizophrenia. 相似文献

The symptom of Anorexia Nervosa is a dramatic statement of the adolescent's need for an internal structure to regulate her sense of self. She was unable to develop this structure during infancy due to the need for the infant to meet her mother's narcissistic needs. Therefore, the infant was not able to internalize the mirroring function (of the mother) which would have allowed her to acquire her own empathetic structure to regulate her self worth. Consequently, empathy must be utilized in the treatment relationship to facilitate the formation of a compensatory structure of the self which will, in turn, promote recovery from Anorexia.Ms Reilly graduated in 1986 from Boston College, Graduate School, Social Work. 相似文献

In this paper a set of residuals for the multivariate linear regression model is introduced. These residuals are shown to be independent with known distributions which do not depend on the parameters of the model. Transformations of the mentioned residuals may be used to construct exact α goodness-of-fit tests for the multivariate regression model. 相似文献
