Classification of obesity varies between body mass index and direct measures of body fat in boys and girls of Asian and European ancestry

Body mass index is a common proxy for proportion of body fat. However, body mass index may not classify youth similarly across ages and ethnicities. We used sex- and ethnic-specific receiver operating characteristic curves to determine how obesity classifications compared between body mass index and dual energy x-ray absorptiometry-based body fat percent. Male and female participants 9- to 18-years-old (n = 944; 487 female) were measured 1 to 13 times (1999–2012; 4,411 observations). Body mass index identified < 50% of those classified as obese from body fat percent. Specificity was 99.7%, and sensitivity was 35.8%. Using area under the curve and standard error values, body mass index performed significantly better for: Male versus female at 10 years, Asian versus European female except at 13-, 15-, and 16-years-old, Asian female versus male except at 10- and 15-years-old, and for European male versus female, 9- to 11-years-old (p < .05). Our findings provide evidence that users of body mass index should use caution when comparing body mass index across age, sex, and ethnicity.     

Unpacking the CRT in Negotiating White Science

In this forum, we summarize CRT’s origins, tenets common to most CRT writings, and CRT’s evolution. We discuss Yerrick’s article Negotiating White Science with respect to certain CRT premises. Specifically, we use the CRT tenet of racism as emphasized in first- and second-generation CRT and CRT elements liberal racial ideology and voices of color to critically examine Yerrick’s propositions.     

Adapting the graduation efficiency index to provide a consistent basis for assessment of student progress towards graduation

Graduation efficiency is of top concern for institutions of higher education throughout the world. Increasingly, accountability metrics have come under scrutiny as policymakers seek to ensure public resources are efficiently used. Traditionally, higher education policymakers in the USA and Europe have used graduation rate as an accountability measure to assess a university’s efficient use of resources. This time-to-degree method, however, does not take into account the shift in student demographics from a traditional full-time student to the diverse group of students pursuing higher education through varied paths, including balancing work with reduced course loads, studying abroad, completing internships, among others. These changes suggest additional accountability measures are needed to accurately capture student progress as it relates to resource utilisation. This research adapts the Graduation Efficiency Index proposed by Gillmore and Hoffman (1997) to a cohort-based model to allow for evaluating retention policies implemented by cohorts to improve student progress.     

Sleepless in Chicago: tracking the effects of adolescent sleep loss during the middle school years

The influence of the sleep patterns of 2,259 students, aged 11 to 14 years, on trajectories of depressive symptoms, self-esteem, and grades was longitudinally examined using latent growth cross-domain models. Consistent with previous research, sleep decreased over time. Students who obtained less sleep in sixth grade exhibited lower initial self-esteem and grades and higher initial levels of depressive symptoms. Similarly, students who obtained less sleep over time reported heightened levels of depressive symptoms and decreased self-esteem. Sex of the student played a strong role as a predictor of hours of sleep, self-esteem, and grades. This study underscores the role of sleep in predicting adolescents' psychosocial outcomes and highlights the importance of using idiographic methodologies in the study of developmental processes.

Focusing attention on the individual in identification of gifted black students

Despite efforts to desegregate and promote equal opportunity, Black students have a minimal role in gifted programs. Efforts to improve this situation must begin with a focus on the individual student. Classroom teachers need assistance from gifted and talented coordinators with nomination procedures. Information regarding standardized tests, perceptions of low achievement, and the characteristics of Black achievers is essential for improving nomination. The second step to increasing minority participation in gifted programs is to implement a multi‐criteria assessment profile. Compiled by the gifted and talented coordinator with the continued assistance of the classroom teacher, this profile should include a case study documenting gifted characteristics, family background information, and peer evaluations. Standardized test scores may play a minor role. Successful identification of gifted Black students depends on a thorough examination of the individual.
