The association between anger, lipid profiles, and glucose levels were examined in this study of 103 middle aged, healthy women. A principal component factor analysis of Spielberger's Trait Anger and Anger Expression scales yielded two anger factors: Impulsive Anger-Out and Neurotic Anger. Impulsive anger-out significantly predicted a negative lipid profile (high total serum cholesterol (TSC), low density lipoproteins (LDL), TSC/HDL (high density lipids), and triglyceride levels) and heightened glucose levels, but only in physically unfit women. Neurotic anger did not predict lipid and glucose levels. These findings parallel previous findings regarding the two anger dimensions and CHD, with only impulsive anger-out predicting CHD. Furthermore, our findings indicate that the protective effect of physical fitness, previously documented for men, also occurs in women.
