生活習慣病と睡眠障害(シンポジウム : 心身機能と睡眠障害,2006年,第47回日本心身医学会総会(東京))  [in Japanese] Relationship between Sleep DIsorders and Lifestyle-related Diseases(Symposium : Psychosomatic Function and Sleep Disorders)  [in Japanese]

不眠および抑うつと生活習慣病に関する実態について,勤労者5,747名(平均年齢43.8歳)を対象に調査を行った.生活習慣病をもつ人は,もたない人に比べて不眠および抑うつの割合が高かった.また,生活習慣病を治療している人よりも放置している人でその傾向は強くなり,特に三疾患を合併しながら放置している人で顕著であった.逆に,不眠および抑うつの人はない人に比較して,有意に生活習慣病率が高かった.さらに,不眠経験者の多くは自発的に医師に相談をすることも,医師から睡眠に関する問診を受けることもなく,無治療で放置するか,自己判断で寝酒や市販薬に頼る場合が多く,睡眠薬による適切な治療を受けていない実態が今回の調査結果から明らかとなった.以上の結果から,生活習慣病は不眠や抑うつと相互に密接に関わっていることが示唆された.

The relationship between sleep disorders and lifestyle-related diseases was investigated in 5,747 subjects (mean age 43.8 years). The percentage of those with insomnia and depressive state was higher, in those who had lifestyle- related diseases than in those who did not. Moreover, the incidence of insomnia was higher in those who left lifestyle- related diseases untreated than in those who were under proper treatment, and was highest in those who left 3 major lifestyle-related diseases untreated. Conversely, the incidence of lifestyle-related diseases was significantly higher in those who had insomnia than in those who did not. Also, many subjects with insomnia were found to have left insomnia untreated without consulting a physician or being inquired by a physician about sleep. They tend to take a nightcap or OTC drugs by their own judgments, and do not receive appropriate treatment by prescription drugs. These results confirmed a close relationship between lifestyle-related diseases and sleep disorders, and suggested that insomnia can be a risk factor of lifestyle-related diseases.
