Alcohol consumption and higher incidence of impaired fasting glucose or type 2 diabetes in obese Korean men.

It is inconclusive whether moderate alcohol consumption reduces the diabetes risk. We observed the development of impaired fasting glucose or type 2 diabetes according to the amount of alcohol intake and body mass index. The annual health evaluation data of 2,500 male workers from 2002 to 2006 were reviewed retrospectively deleting personal identification code. The information contained sex, age, medical history, smoking status, alcohol consumption, participating regular exercise, anthropometric, and biochemistry measurement. Impaired fasting glucose or diabetes was determined when fasting plasma glucose was > or =100mg/dL. Thousand seven hundred seven subjects were eligible after excluding medical history of diabetes or fasting glucose > or =100mg/dL at baseline. The relative risks of its development in group of taking 1-14, 15-29, and > or =30.0g ethanol were 0.842 (95% confidence interval [CI], 0.603-1.176), 1.068 (95% CI, 0.736-1.551), and 1.019 (95% CI, 0.662-1.568) within normal weight group, 1.164 (95% CI, 0.795-1.705), 1.421 (95% CI, 0.947-2.133), and 1.604 (95% CI, 1.031-2.495) within overweight group, and 1.498 (95% CI, 1.042-2.153), 1.634 (95% CI, 1.091-2.447), and 1.563 (95% CI, 1.019-2.396) within obese group each after adjusting age, family history of diabetes, smoking, exercise, serum fasting glucose, aspartate aminotransferase, and gamma-glutamyltransferase with nondrinkers as a reference group. Not only high alcohol consumption but also moderate drinking was related with higher incidence of impaired fasting glucose or diabetes in obese Korean men.

Korean travelers' knowledge, attitudes, and practices regarding the prevention of malaria: measures taken by travelers departing for India from Incheon International Airport.

BACKGROUND: Although many Koreans travel each year to countries where malaria is present, few data are available on the knowledge, attitudes, and practices of Koreans with regards to malaria. METHODS: The study was conducted in the departure lounge of Incheon International Airport in May 2006. A 22-item questionnaire was administered to Korean travelers whose travel destination was India. RESULTS: Of 188 respondents, 24% had sought pretravel health information. Independent predictors for seeking pretravel health information were the following: being a Korean woman, longer duration of travel, planning to travel independently or to a rural area, and perceived risk of malaria. A total of 47% of travelers answered that they had not perceived any risk of malaria, and only 7% of travelers carried malaria prophylaxis. CONCLUSIONS: There is an urgent need for increased awareness about travel-related infectious diseases (especially malaria) among Korean travelers, and they should be encouraged to seek pretravel health information.
