Factor analysis of climacteric symptoms in Japan

Sexual-vasomotor symptoms constitute a robust menopausal and kōnenki symptom grouping among Japanese women, but do not include night sweats or the foreign word hotto furasshu, yet do include chilliness, which may reflect thermoregulatory instability. Overlap of factors displaying significant differences between menopausal and kōnenki groups indicate a transition to a more medicalized concept of kōnenki in use by Japanese women.
