Evidence of Higher Oxidative Status in Depression and Anxiety. Oxidative Med Cell Longev. 2014;2014:430216.

We include 63 individuals (28 males and 35 females aged between 20 and 65 years). The validated anxiety State-Trait Anxiety Inventory questionnaire and the validated BDI (Beck Depression Inventory) questionnaire were used to evaluate anxiety and depression. Antioxidative status was determined by measuring the redox potential of urine collected in standard conditions. Correlation of the antioxidant capacity of urines evaluated using the ferric ion/specific dye method or through redox potential using the platinum electrode demonstrated the suitability of this last procedure. We found that normal anxiety state values corresponded to low urine redox potentials, whereas higher anxiety states were associated with high urinary redox potential. We also found that individuals with normal BDI values had significantly lower urine redox potentials than individuals with higher BDI values.enghttps://creativecommons.org/licenses/by/3.0/AntioxidantsAnxietyOxidative StressAgedAdultHumansDepressionMiddle AgedMaleFemaleOxidantsLinear Modelsresearch articleAttribution 3.0 Unported24876911201443021610.1155/2014/4302161942-0994Oxidative Medicine and Cellular Longevityopen accessModelos LinealesOxidantesFemeninoMasculinoHumanosPersona de Mediana EdadDepresiónAncianoAnsiedadEstrés OxidativoEncuestas y CuestionariosAntioxidantesAdulto2-s2.0-84901277100335735100001L373140570
