Examining the Association Between Body Mass Index and Weight Related Quality of Life in Black and White Women

Obesity not only increases risk for morbidity/mortality, but also impacts the quality of life of obese individuals. In the United States, black women have the highest prevalence of obesity of any other group with approximately 80% of black women over age 20 having a body mass index (BMI)????25?kg/m². We aimed to examine the association between BMI and quality of life in this high risk population compared to this association in white women, using the Impact of Weight on Quality of Life (IWQOL)-Lite questionnaire. Data from 172 black women (mean BMI?=?35.7; age?=?40.5) and 171 white women (mean BMI?=?35.5; age?=?40.4) were collected between 2000 and 2010 analyzed in 2010. The mean IWQOL-Lite total score was 81.6 for black women compared to 66.9 for white women, a statistically significant difference. Hierarchical linear regression models revealed a significant BMI-by-race interaction indicating that the relationship between BMI and IWQOL-Lite score was moderated by race. Our findings suggest notable differences in weight-related quality of life in black and white women. At similar BMIs, black women consistently reported better quality of life than white women on all IWQOL-Lite subscales. The greatest difference in IWQOL-Lite scores between black and white women was seen in the self-esteem subscale. Additional research is needed to understand how to incorporate the weight perspectives of black women into weight management messages and interventions.     

Negative information: both presence and absence of spatial pattern elements guide rats' spatial choices

Rats learn the spatial pattern in which hidden caches of food are located. Once the pattern is learned, finding one or more baited locations provides (positive) information about the remaining baited locations. In the present experiment, we examined whether negative information (the absence of food in a location) would also be used in locating the remaining baited locations. Rats were tested in an apparatus containing a matrix of vertical poles, on top of which food could be hidden. At the beginning of the trial, the location of the baited poles was unpredictable, but the poles were always arranged in a linear pattern. The rats learned the pattern and used both positive and negative information in locating baited poles.

Social experience and school bullying

The goal of the present study is to investigate the relationship between school bullying and various aspects of the urban and scholastic environment where participants live, such as sense of community, exposure to dangerous and violent situations within the neighbourhood, perceptions of the safety of the neighbourhood and perceptions of the school environment. The research, performed in Ercolano, a town near Naples, covered the whole of Ercolano's population (n = 734) of 7th, 10th and 13th grade students. Data were analysed using a multivariate analysis of variance. Results showed that bullying role (pure bullies, pure victims, bully victims, not‐involved) is significantly associated with the way subjects perceive their exposure to dangerous and violent situations within the neighbourhood, their relationship with classmates and their relationship with teachers. Pure bullies and bully victims are especially likely to experience dangerous and violent situations in the neighbourhood where they live and have a more negative perception of their relationship with teachers; for pure victims and bully victims, a significant association is obtained with negative perceptions of relationships with classmates. These findings suggest the need for intervention strategies that extend beyond the classroom to the broader community and neighbourhood. Copyright © 2008 John Wiley & Sons, Ltd.     

Temperament, ADHD and peer relations among schoolchildren: the mediating role of school bullying

The goal of the study is to investigate the link between temperament, attention-deficit hyperactivity disorder (ADHD) symptoms, social preference, bullying and victimization. The study sample consisted of 195 children attending the fourth and fifth grade (age 8-10), their mothers and their teachers. A multiinformant approach was used: mothers were interviewed about the temperament of their children; teachers were asked about ADHD symptoms; children responded to a peer nominations inventory designed to investigate their roles as bullies and/or victims and their social preferences (liked and disliked peers). A Structural Equation Model multigroup analysis (males and females) was used to test the relationships among variables hypothesized by the authors. The analysis showed that temperamental variables have a direct relation to ADHD symptoms, that ADHD has a direct relation to bullying behavior in males and to victimization in females and that bullies and victims are less well accepted than peers who belong to neither category. ADHD has only an indirect relation to social preference through the mediating role of school bullying.
