In a general population, women are more likely to use CAM and to be interested in receiving CAM [1][2][3][4] . A cross-sectional study in the United States showed a strong association of female gender with CAM use across ethnic minorities 5) . In patients in northern Israel, women visiting primary care clinics used CAM more often than did men 6,7) . Several studies have shown more frequent use of CAM by women than by men for chronic and life-threatening illnesses [8][9][10] .

The frequencies of personal use of aromatherapy and yoga by female students were significantly higher than those by male students (p < 0.05). Female students had high levels of interest in aromatherapy, massage, yoga and chiropractic, while male students had high levels of interest in Japanese herbal medicine, massage and psychotherapy.

Conclusions:Female students are more likely to have positive and favorable attitudes toward CAM than are male students in Japan. CAM modalities that female students had an interest in and used were different from CAM modalities for acupuncture, Ayurveda, homeopathy, massage, chiropractic, reflexolo...
