This investigation sought to identify anxiety responses to weight measurement, assessed by verbal report and cardiovascular reactivity CCR3 (systolic blood pressure, diastolic blood pressure, heart rate), which might differentiate females with either high or low self-reported bulimic behavior. Secondar i ly,, the study attempted to examine specific autonomic nervous system (ANS) arousal patterns of each group over time. The Bulimia Test (BULIT), Body Dissatisfaction Scale (BD), and a demographic questionnaire were administered to 105 undergraduate females at The University of North Texas. Based on BULIT scores, females were divided into high or low bulimic behavior groups. Of the 105 females screened, forty participated in the experiment which consisted of four phases: relaxation, anticipation of weight measurement, weight measurement, and recovery. Subjects had no prior knowledge of the weight stressor until presentation during the experiment. Results showed that subjects' notion of ideal weight was substantially lower than measured weight. During weight measurement, all subjects reported increased anxiety although the high group reported significantly more anxiety. Contrary to prediction, no significant group differences in CR were found when repeated measures multivariate analysis of variance (MANOVA) was performed. Orthogonal polynomial trend analysis was done with pooled groups, resulting in significant within-subject trends for all cardiovascular measures. There was also a significant group by time of measurement interaction for heart rate during the weight measurement phase. Correlational analyses failed to produce significant results between verbal report of anxiety and CR. There was, however, a significant correlation between BULIT and BD scores. It was concluded that heightened subjective anxiety during weight measurement could not be attributed to group differences in CR. Regarding ANS arousal patterns, mixed evidence of active and passive coping was seen. Nevertheless, both psychological and physiological measures supported an overvaluation of female thinness consistent with societal trends regardless of group membership. Implications of findings were discussed along with suggestions for future research.

Incidence of childhood obesity has increased dramatically within the last 30 years. Childhood obesity is of concern because of the associated health problems, and because childhood obesity often tracks into adulthood. There is a clear association between activity-level and obesity. Therefore, it is important to consider physical activity patterns in the treatment and prevention of childhood obesity. Childhood is a key time period to intervene in the formation of habits and patterns associated with physical activity that may reduce obesity. To date, few studies have focused on the level of examining obese children individually. This case study focused on the physical activity patterns of 4 obese 6-10 year olds (two boys, two girls). All of the participants were above the 99th percentile for weight and had a body fat percentage exceeding 45%. Lipid profiles of the participants revealed that three of the four had high total cholesterol, indicating an increased risk for cardiovascular disease. All of the participants were close to or exceeded the waist to hip ratio value that indicates very high risk for cardiovascular and related diseases (>0.82 for boys, >0.94 for girls). Use of the Caltrac accelerometer, KIHD 24-Hour Total Physical Activity Record and System for Observing Fitness Instruction Time revealed that the obese 6-10 year old participants averaged 1.85 minutes of moderate to vigorous physical activity (MVPA) per lunch recess time. When extrapolated, the data revealed that the participants spend less than 20 minutes a day in MVP A. This is less than MVP A norms of children in the same age group. The obese participants were not meeting the current recommendations for 60 minutes or more a day for MVPA. Furthermore, the activity patterns of the participants differ from those of normal weight children. Although children in general and the participant's tend to choose low level activity over MVP A, the participants spent more than 16.5 hours per day in sedentary physical activity, which is more than their normal weight counterparts (10.4 +/- 0.8).
