Journal of Circadian Rhythms 2011 9 9 http content 9 1 9 JOURNAL OF CIRCADIAN RHYTHMS RESEARCH Open Access Relationship between psychosomatic complaints and circadian rhythm irregularity assessed by salivary levels of melatonin and growth hormone Mitsuo Nagane 1 Rie Suge2 and Shu-Ichi Watanabe2 Abstract Background In university health care settings students with psychosomatic complaints often have chronotypic problems. For this reason we investigated a potential connection between psychosomatic complaints and circadian rhythm irregularity assessed by salivary levels of melatonin and growth hormone. Methods Fifteen healthy students between 21 and 22 years of age were examined for physiological parameters of chronotypes based on melatonin and growth hormone secretion patterns using a fluorescence enzyme immunoassay. Salivary samples were collected from subjects at home five times each day 20 00 24 00 04 00 08 00 and 12 00 h . In addition the subjects rated their psychosomatic symptoms twice at 08 00 and 20 00 h . Results A group with irregular circadian rhythm of melatonin ICR showed more psychosomatic complaints than a group with the regular circadian rhythm RCR especially for anxiety. Conclusion Psychosomatic symptoms particularly anxiety may be associated with irregularity in melatonin and growth hormone rhythms which can be altered by basic lifestyle habits even in healthy students.

Background Students suffering from psychosomatic complaints often have basic lifestyle problems such as short sleep duration 1 and nocturnal lifestyle 2 . An increasing number of human health problems are related to dysfunction or desynchrony of the circadian system 2-4 . Psychosomatic complaints refer to symptoms experienced by the individual with physical symptoms . head ache and psychological .
