Differences in insulin secretion and sensitivity of Caucasian and African American prepubertal children.

Objective: To investigate whether differences in body composition of African American children (AA) and Caucasian children (C) explain differences in insulin sensitivity and secretion.

Study Design: Prepubertal nondiabetic children (31 AA and 54 C) were studied; 84% were overweight. Participants underwent a 2-hour hyperglycemic clamp, to estimate insulin sensitivity (SI(clamp)) and secretion, and dual energy x-ray absorptiometry, to assess body composition.

Loss of control over eating, adiposity, and psychopathology in overweight children.

Objective: To investigate the relationship between loss of control over eating, adiposity, and psychological distress in a nontreatment sample of overweight children.

Method: Based on self-reports of eating episodes, 112 overweight children, 6-10 years old, were categorized using the Questionnaire of Eating and Weight Patterns-Adolescent Version into those describing episodes of loss of control over eating (LC), and those with no loss of control (NoLC). Groups were compared on measures of adiposity, dieting, and eating behavior, and associated psychological distress.
