Abstract
In female, psychophysiological change have been show to arise through menstrual cycle. The purpose of study was to evaluate the influence of the normal menstrual cycle on mood, cognition and health behavior.
We used health behavior model (Interaction Model of Client Health Behavior, IMCHB) as the conceptual framework and examined variations in mood, cognition and health behavior in menstrual cycle. Mood scales (STAI. MACL. MDQ) and cognition tasks (Digit symbol, Stroop-c, Substaction, MDT, Time estimation) were administrated to 22 women (18-44 years) who had normally menstrual cycle in each phases of menstrual cycle. Also these subject have performed weight loss's behavior (health behavior) for three months.
The result were as follows
1) 2 of 11 factors in MACL or dimensions of mood varied significantly with phase of the menstrual cycle. Concentration was highest in follicular phase. Fatigue was highest in the luteal phase. The other side, there was not an association between cognitive tasks and phase of the menstrual cycle. No systematic relationship were found.
2) There were associations between affective response and the first health outcome and also between cognitive appraisal and the second health outcome in IMCHB.
The finding could explain that health behavior was affected by phase of the menstrual cycle.
