Abstract
Recent evidence suggests that naturally occurring low cholesterol concentrations ( Fasting lipid samples were collected at the same time as health history. Trait depression and anxiety were assessed using the Neuroticism, Extraversion, Openness-Personality Inventory (NEO-PI) depression subscale and Spielberger's Trait Personality Inventory (STPI) anxiety subscale. Analyses were conducted using both univariate and multivariate procedures. NEO depression was inversely associated with total cholesterol (p = .027), triglycerides (p = .012), and the ratio of total cholesterol to high-density lipoprotein cholesterol (p = .059). Similarly, STPI anxiety was inversely associated with total cholesterol (p = .002), low-density lipoprotein cholesterol (p = .016), triglycerides (p = .024), and ratio of total cholesterol to high-density lipoprotein cholesterol (p = .075). These associations were significant after adjustment for age, body mass index, physical activity, oral contraceptive use, and hostility. Neither depression nor anxiety was associated with high-density lipoprotein cholesterol. Univariate analyses indicated that women with low total cholesterol concentrations ( In healthy young adult women, low lipid and lipoprotein concentrations are inversely associated with trait measures of depression and anxiety. These findings are independent of age, body mass index, physical activity, and other factors known to influence lipid concentrations.
