＜目的＞糖尿病患者における常習飲酒者の実態と関連因子を明らかにする。＜対象と方法＞対象は，当院通院中の糖尿病患者866例(男性/女性：545例/321例，平均年齢：67.1±11.0歳)である。問診にて，アルコール摂取量を聴取し，エタノール換算60g/日以上，5年以上継続する例を常習飲酒者として，常習飲酒と関連する因子を検討した。

　＜結果＞常習飲酒者は，29.2％にみられた。常習飲酒者は，非常習飲酒者と比べ，肝線維化の指標であるFIB4 index 2.67以上，高血圧，脳血管障害の頻度が高頻度であった。

　＜結語＞常習飲酒者においては，肝線維化，脳血管障害の発症のリスクが大きく，療養指導においてこれらに対する配慮の必要性が考えられた。

   Objective：To elucidate the frequency of habitual alcohol drinking and related factors in diabetic patients. Methods and Patients：A total of 866 diabetic patients (545 men, 321 women) with a mean age of 67.1 ± 11.0 years were included in this study A patient who had been drinking 60 g of alcohol or more per day, in ethanol conversion, for 5 years or more was defined as a habitual alcohol drinker (drinkers). The frequency of habitual alcohol drinking and the related backgrounds were examined. Results：Drinkers was recorded in 253 patients, 29.2% (44.6% male and 3.1% female). The frequency of FIB4 index 2.67 or higher, high blood pressure and cerebrovascular disease (CVD) among drinkers were higher than among non- drinkers. Conclusion：The risks of developing hepatic fibrosis and CVD were high in drinkers, and it is considered necessary to consider these factors in medical treatment for diabetes.
