Background
Dietary supplements affect the health and disease status of Koreans. We assessed the patterns of dietary supplements use and the related factors in Korean adults from the 2005 Korea National Health and Nutrition Survey (KNHANES). Methods: Among the subjects, 2,024 men and 2,811 women underwent all the three parts of 2005 KNHANES, which consisted the health survey, the health examination, and the nutritional survey. Reported supplements were classifi ed according to the 2008 Korea Food and Drug Administration Notification. We assessed the relationship between supplements use and socioeconomic state, health behaviors, and chronic diseases. Results: Twenty-nine percent of Korean adults was taking dietary supplements. Vitamin/mineral supplements were the most commonly taken one. Glucosamine/mucopolysaccharide, ginseng, spirulina/chlorella, omega-3, and aloe followed in listing. Supplement users were likely to be woman and middle-aged. Supplement use was associated with older, high income, with spouse, higher education, urban-living, regular exercise, non-smoker, and lower BMI. Musculoskeletal diseases were associated with supplement use. Conclusion: Dietary supplement use is prevalent in Korean adults. The supplement use was associated with some demographics characteristics, health behavior, and chronic diseases. These factors should be considered when evaluating the effi cacy of dietary supplements. Citations Citations to this article as recorded by
Background: We assessed the state of diabetes control in Korean adults from the 2001 Korean National Health and Nutrition Survey. Methods: A total of 271 adult diabetes patients (125 males, 146 females) were identified from the health interview survey. Diabetes control status was assessed by the American Diabetic Association (ADA) recommendations. Socioeconomic characteristics and the health status were assessed by an interview and the health- related behavior was assessed by self-questionnaire. A one-day 24-hour recall was used for the dietary assessment. Blood pressure and anthropometric measurements were done. Fasting blood was drawn for glucose, HbA1c, and lipids profile. Results: The proportions of patients reaching the recommended goals for fasting plasma glucose (≤130 mg/dl), HbA1c (＜7%), blood pressure (＜130/80 mmHg), low density lipoprotein cholesterol (＜100 mg/dl), triglyceride (＜200 mg/dl), and high density lipoprotein cholesterol (＞45 mg/dl for males, ＞55 mg/dl for females) were 57.2%, 19.9%, 24.4%, 27.8%, 64.5% and 20.7%, respectively. Body mass index, and smoking in males and age, and diabetes duration in females were associated with HbA1c level. Conclusion: This study shows that diabetes in Korean adult is not adequately controlled. National effort is needed to achieve the recommended treatment goals and to manage modifiable risk factors such as obesity and smoking. (J Korean Acad Fam Med 2008;29:658-667)
Background
: Underreporting in self-reported dietary survey is a potential source of bias in nutritional epidemiology. We assessed if dietary underreporting existed in the 2001 Korean National Health and Nutrition Survey (KNHANS) and evaluated the health related factors and nutrients associated with dietary underreporting. Methods : The subjects were 2,552 men and 3,335 women, 18 years of age or older, with a complete 24 hour recall and physical examination data including height and weight. Basal metabolic rate (BMR) was calculated from weight and height using WHO equations. Questionnaire to assess daily physical activity and regular exercise was done. EI/BMR ratio was used to evaluate dietary underreporting. Results : The mean EI/BMR ratio of Korean men and women were 1.43±0.56 and 1.41±0.57, respectively. Among the total, 20.6% of men and 22.8% of women reported their energy intake lower than their BMR. Age was negatively related with EI/BMR ratio only in women (P＜0.001). Body mass index, education level, and household income were negatively and daily physical activity was positively associated with the EI/BMR ratio in both sexes. Lower EI/BMR ratio was significantly associated with lower reported fat energy density (% of energy intake) and higher reported carbohydrate and protein energy densities. The EI/BMR ratio was related negatively with nutrient energy densities of Vitamin C, Calcium, and Iron. Conclusion : We could confirm selective dietary underreporting in the 2001 KNHNS. Caution should be paid on the interpretation of the nutrition survey data and efforts should be exercised to reduce dietary underreporting at data collection stages.
