Background: We sought to expand on preliminary findings suggesting that anabolic-androgenic steroids produce psychiatric effects in some athletes who use them. Methods: We compared 88 athletes who were using steroids with 68 nonusers, using the Structured Clinical Interview forDSM-III-Rto diagnose psychiatric syndromes occurring in association with steroid use (if applicable) and in the absence of steroid use. Demographic, medical, and laboratory measures were also performed. Results: Steroid users displayed more frequent gynecomastia, decreased mean testicular length, and higher cholesterol—high-density lipoprotein ratios than nonusers. Most strikingly, 23% of steroid users reported major mood syndromes—mania, hypomania, or major depression—in association with steroid use. Steroid users displayed mood disorders during steroid exposure significantly more frequently than in the absence of steroid exposure (P<.001) and significantly more frequently than nonusers (P<.01). Users rarely abused other drugs simultaneously with steroids. Conclusion: Major mood disturbances associated with anabolic-androgenic steroids may represent an important public health problem for athletes using steroids and sometimes for the victims of their irritability and aggression.

Cocoa contains more phenolic antioxidants than most foods. Flavonoids, including catechin, epicatechin, and procyanidins predominate in antioxidant activity. The tricyclic structure of the flavonoids determines antioxidant effects that scavenge reactive oxygen species, chelate Fe2+ and Cu+, inhibit enzymes, and upregulate antioxidant defenses. The epicatechin content of cocoa is primarily responsible for its favorable impact on vascular endothelium via its effect on both acute and chronic upregulation of nitric oxide production. Other cardiovascular effects are mediated through anti-inflammatory effects of cocoa polyphenols, and modulated through the activity of NF-κB. Antioxidant effects of cocoa may directly influence insulin resistance and, in turn, reduce risk for diabetes. Further, cocoa consumption may stimulate changes in redox-sensitive signaling pathways involved in gene expression and the immune response. Cocoa can protect nerves from injury and inflammation, protect the skin from oxidative damage from UV radiation in topical preparations, and have beneficial effects on satiety, cognitive function, and mood. As cocoa is predominantly consumed as energy-dense chocolate, potential detrimental effects of overconsumption exist, including increased risk of weight gain. Overall, research to date suggests that the benefits of moderate cocoa or dark chocolate consumption likely outweigh the risks. Antioxid. Redox Signal. 15, 2779–2811.
