title: Impact of stress on objectively recorded menopausal hot flushes and on flush report bias.
abstract: The hot flush (or flash) is the most widely reported menopausal symptom. Anecdotal reports suggest that women experience more hot flushes when stressed. Although stress may actually trigger hot flushes, another possibility is that women under stress may be more aware of the physiological changes associated with flushes and, therefore, more likely to report them. The goal of this study was to test these hypotheses by investigating the association between stress and both objective (i.e., physiologically recorded) and subjective hot flushes. Twenty-one postmenopausal women who reported having frequent hot flushes each underwent psychophysiological monitoring during stressful and nonstressful laboratory sessions. Significantly more objective flushes were recorded during the stress session than during the nonstress session. The stress manipulation, however, did not affect subjects' propensity to report flushes. These results suggest that the observed association between reported hot flushes and stress is not due to changes in report bias. The physiological mechanisms through which stress may stimulate hot flushes are discussed.
