Development of dietary behavior items available in Korea National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: Given that the indicators related to chronic diseases are important to evaluating goals of the national health policy, the aim of this study was to develop dietary behavior items available in the Korea National Health and Nutrition Examination Survey. METHODS: The dietary behavior items were developed based on the literature reviews, need assessment of the field, expert focus-group interviews, and expert advisory meeting. Questions for each dietary behavior item were developed by reflecting on environmental, personal, and behavior factors of the ecological frame and then revised through expert focus-group interview and expert advisory meeting. The understanding and reliability of the developed questionnaire were assessed by cognitive interview and test-retest reliability. RESULTS: The developed items were sodium and salt intake, added and simple sugar intake, enough time to consume a meal for all ages, caffeine drinks and fresh/healthy food intake for children and adolescents, and limited dietary intake, fresh/healthy food intake for seniors. In most questions except some questions on sodium and salt intake, subjects understood over 70% and consistency of responses based on the kappa values was acceptable. CONCLUSION: Developed dietary behavior items are expected to be useful for evidence-based nutrition policy, interventions and research targeting dietary patterns through investigating and monitoring dietary behavior patterns.

The Epidemiologic Study on Prevalence of Hypertension by Classification of JJNC-5 in Adult Korean Male Workers Resident in Pohang / 대한내과학회지

OBJECTIVES: To establish Korean prevalence of hypertension, we surveyed male workers resident in Pohang by classification of JNC-5(FIFTH JOINT NATIONAL COMMITTEE CLASSIFICATION OF BLOOD PRESSURE) and further analysed association with age, working condition, body weight, fasting blood sugar, total serum cholesterol, tryglyceride, uric acid, drinking habit, smoking habit and amout of physical exercise. METHODS: We studied 13,052 male workers resident in Pohang from January 1993 to Novemver 1993. Each male worker completed a medical and occupational questionaire and blood pressure was taken. All blood sample were taken at venous blood under fasting state at morning. RESULTS: 1) The overall prevalence rate of hypertension by classification of JNC-5 was 16A percent and most of all hypertensives were in stage 1 and 2. 2) The systolic and diastolic blood pressure increased significantly with age. 3) The prevalence of hypertension in shift workers was significantly higher than that of nonshift workers. 4) The prevalence of hypertension in the subjects of overweight, high fasting blood sugar, cholesterol, triglyceride and uric acid level was significantly higher than that of normal criteria group. 5) The prevalence of hypertension in smokers was not significantly higher than that of nonsmokers. 6) The prevalence of hypertension in nonalcoholics was significantly lower that that of heavy alcoholics. 7) The prevalece of hypertension of nonexerciser was significantly lower than that of heavy exerciser. CONCLUSION: The prevalence of hypertension by classitication of JNC-5 at male workers was 16.4percent. Increasing age, shift work, overweight, high fasting blood sugar, high serum total cholesterol and triglycerides ad uric acid level, heavy alcohol drinking significantly increased prevalence of hypertension.
