Objective: There is an ever growing body of literature which endorses the view that sleep evolves with normal aging and also modified by being either a man or woman. Changes in sleep patterns have been consistently described from childhood, through adolescence, adulthood and into old age, with sleep continuity measures seen to decline with aging and to a greater extent in men compared to women. However, when sleep is evaluated using subjective means, elderly women are more likely to report poor quality sleep compared to men. We evaluated the subjective (self-reported) and objective (polysomnographic and EEG power spectra) of 181 healthy subjects under normal and experimental challenge by traffic noise with three defined aims; firstly, to describe the nature of aging and sex-related effects upon sleep. Secondly, to evaluate the inter-relationship between objective (PSG & spectral) and subjective (self-reported) measures of sleep. Finally, to assess the influence of these age and sex upon sleep propensity when sleep is experimentally challenged (ESF).
