Anger, stress and blood pressure in overweight children.

Among adults, trait anger, patterns of anger expression, and stress have been associated with blood pressure (BP). Less apparent is the effect of these variables on BP in overweight and obese children. To characterize the relationships between these psychological variables and BP, the authors conducted a secondary analysis of data from 73 overweight and obese 9- to 11-year-old children. Findings indicate a positive correlation between trait anger and systolic BP (SBP). Regression results indicate that the overall model significantly predicted SBP by explaining 15.4% of the variance and that trait anger was a significant predictor of SBP.
