Background: A previous large-scale cohort study investigated the relationship between coffee intake and the progression of diabetes mellitus in the United States. However, studies on the effects of coffee on diabetes are rare in South Korea. Therefore, this study assessed the amount and method of coffee intake in Koreans in order to determine if coffee intake has a prophylactic effect on diabetes progression.Methods: This study included 3,497 prediabetic patients from a single medical institution, with glycated hemoglobin levels ranging from 5.7% to 6.4%. Cross-tabulation and Kaplan-Meier survival analyses were performed to compare patients with and without diabetes progression based on the frequency and method of coffee intake. Cox proportional hazard analysis was performed to correct for confounding variables. Results: The observation period (mean±standard deviation) was 3.7±2.3 years. Kaplan-Meier survival analysis revealed that the risk of diabetes progression was lowest in patients who drank black coffee three or more times per day (P=0.036). However, correction for confounding variables in Cox proportional hazard analysis revealed that, while the risk was lower for the patients who typically consumed black coffee than for those who mixed creamer and sugar into their coffees, the difference was not significant. Conclusion: The results of this study suggest that drinking coffee without sugar and creamer at least three times daily has the greatest preventive effect on diabetes onset.

연구배경: 일반적으로 체중이 증가 할수록 골밀도가 증가하고 골절을 예방하는 것으로 알려져 있다. 그러나 최근 반대의 의견을 제시하는 몇몇 연구가 발표되면서, 이는 체중을 구성하는 제지방과 체지방의 량에 따라 골밀도가 달라질 수 있음을 시사하게 되었다. 이에 본 연구는 노인에서 신체 조성과 골밀도의 관계에 대하여 알아보고자 하였다. 방법: 골밀도 검사를 시행한 60세 이상의 남성 121명과 여성 416명을 대상으로 골밀도와 체중, 제지방량, 체지방량 그리고 허리둘레와의 관계를 분석하였다. 그리고 신체를 상지, 하지, 몸통으로 구분하여 골밀도와 각 신체 부위의 근육량 및 지방량간의 관계도 분석하였다. 결과: 남성과 여성 모두 체질량지수가 높을수록 골밀도는 높았으며, 체중을 구성하는 성분 중 제지방량이 체지방량보다 골밀도와 높은 연관성이 있었다. 연령과 생활습관, 체중, 키를 보정한 후 남성의 골밀도는 제지방량, 체지방량과 상관관계가 없었으나, 허리둘레와 음의 상관관계를 보였고, 여성의 경우는 제지방량을 비롯한 모든 근육량은 골밀도와 유의한 양의 상관관계를 보였으며, 특히 몸의 근육량보다 사지 근육량이 더욱 밀접한 연관성을 보였다. 허리둘레를 비롯한 모든 지방량은 골밀도와 음의 상관관계를 보였다. 결론: 노인에서 체성분 중 골밀도에 미치는 영향이 큰 것은 체지방량보다 제지방량이었으며, 노인 허리둘레가 클수록 낮은 골밀도를 보였다. 따라서 노인에서 골밀도를 증가시키기 위해서는 근육량을 증가시키고 바람직한 체형을 유지하는 것이 필요할 것으로 사료된다. Background: Traditionally, It is known that bone mineral density (BMD) increases as body weight increases. However, recent epidemiologic studies have described an opposite events. There are controversial issues as to whether lean mass or fat mass might to the most determinant of BMD. Our aim was to evaluate the associations between both lean body mass or fat mass and BMD in elderly. Methods: The design is a cross-sectional analysis. 121 male and 416 female elderly who were all over 60 years of age were had participated in Dual-energy X-ray absorptiometry for BMD and bioimpedance analysis for body composition. The relationships of BMD and body weight, waist circumference, body composition variables were analyzed. Results: In elderly, BMD was higher as body mass index, and lean body mass had more significant correlation with BMD than body fat. After adjusting for age, life style, weight and height, waist circumference was negatively related to BMD in man. In women, lean body mass and muscle mass were positively, waist circumference and fat mass were negatively related to BMD. Limb muscle mass was more correlated with BMD than trunk muscle mass. Conclusion: Lean body mass among body composition, seems to have a greater influence on BMD than fat mass in elderly. Waist circumference as a visceral fat index showed negative effect on bone mass. Therefore, it is considered necessary for the elderly to increase the muscle mass through exercises and to keep desirable body shape for the increasing BMD.

The Effects of Alcohol on Quality of Sleep
Soon-Yeob Park,Mi-Kyeong Oh,Bum-Soon Lee,Haa-Gyoung Kim,Won-Joon Lee,Ji-Ho Lee,Jun-Tae Lim,Jin-Young Kim 대한가정의학회 2015 Korean Journal of Family Medicine Vol.36 No.6
Background: Alcohol is traditionally known to have a relaxing effect. However, persons who consume alcohol in excessive amounts suffer from poor sleep quality and patients with alcohol use disorders commonly report insomnia. In this study, we aimed to evaluate the effects of alcohol use on sleep quality. Methods: A questionnaire-based cross-sectional survey was conducted with 234 men and 159 women who had visited a general hospital. We used structured questionnaires, including Alcohol Use Disorder Identification Test- Korean revised version (AUDIT-KR) and the Pittsburgh Sleep Quality Index-Korean version (PSQI-K). We analyzed the association between scores for all subcategories of the PSQI-K and the AUDIT-KR and then analyzed the correlation between AUDIT-KR and global PSQI-K scores. Results: The global PSQI-K score for men was positively correlated with the AUDIT-KR score (P=0.008) after adjusting for age, chronic disease, tobacco use, exercise, depression, and anxiety. The AUDIT-KR score was significantly associated with subjective sleep quality (P=0.005), sleep duration (P=0.047), and sleep disturbance (P=0.048); it was not associated with sleep latency, sleep efficiency, or daytime dysfunction. Sleep disturbances due to snoring were significantly associated with total AUDIT-KR score (P=0.008). There was no correlation between the global PSQI-K and AUDIT-KR scores for women (P=0.333). However, daytime dysfunction showed a significant association with total AUDIT-KR score (P=0.048). Conclusion: Men with higher AUDIT-KR scores tended to suffer from poor sleep quality. AUDIT-KR scores showed significant correlations with subjective sleep quality, sleep duration, and sleep disturbances in men.
