Survey of Conceptions about Cold in a Local Area Workers' Periodic Health Examination / 가정의학회지

BACKGROUND: To collect basic data which of conceptions about cold by age, sex, education state, economic state, this survey was carried out in a workers' periodic health examination. METHODS: 1,056 workers who are working at the one company were included for this survey from Jun 1 to July 7 2006. We obtained self-reported questionnaire from them. The contents of the questionnaire were the general characteristics of workers, the cause and the management of cold. We analyzed true recognition ratio of conception about cold by age, sex, education state, and economic state. RESULTS: According to sex and economic state, true recognition ratio was not different. According to age, 'Virus', 'Germ', 'Cold weather' were lowest above fifties about the cause of cold. 'Self-limited disease', 'Flu vaccination prevents cold', 'Percussion to chest is helpful to remove sputum', 'Inhaling warm steam is helpful to decrease nasal obstruction', 'Washing hands is helpful to prevent cold', 'Many people crowd in a area are susceptible to cold' were lowest above fifties about the management of cold. According to education state, 'Virus', 'Food' were highest above fifties. Except 'Medicine cures fast', 'Injection therapy cures fast', 'Tonsillectomy prevents cold', the others were highest in the above college education. According to education state by age group, only 'Virus' in the forties and 'Virus, 'Food' in the above fifties were highest. 'Flu vaccination prevents cold' in the twenties, 'Injection therapy cures fast' in the forties, 'Medicine cures fast' and 'Injection therapy cures fast' were lowest in the above college education. CONCLUSION: Age, education level were significantly related to true recognition ratio of conception about cold. So we had to educate low recognition ratio of conceptions.

Association of TV Viewing and Computer Using Habits with Obesity and Obesity Related Lifestyles

BACKGROUND: TV viewing and computer use are sedentary behaviors and recent surveys report that they are associated with obesity in children. Association of these activities with obesity or obesity related lifestyles was investigated in this study. METHODS: Using the database of questionnaires and physical check-ups among 4th to 6th grade elementary school students in Incheon, the association of television viewing and internet using time with obesity and obesity related factors (dietary habits, and physical activities) were investigated. A total of 2,750 students (1,100 normal weighted/1,650 overweight or obese) were included. RESULTS: In the multiple analyses of computer using time among the boys and girls in weekdays and weekends respectively, according to their obesity degree, except for overweight and obese boys in weekends (P<0.001), there were no significant differences examined. Multiple logistic regression revealed that children who watched TV more than 2 hours per day ate faster (OR 1.27), had breakfast more irregularly (OR 1.41) and ate vegetables more rarely (OR 1.53). The children who used computer more than 1 hour per day in weekdays were faster eaters (OR 1.38) and hardly ate fruits (OR 1.26) or vegetables (OR 1.60). In weekends, the children who spent time more than 90 minutes in the computer were faster to eat (OR 1.46), more snack eating (OR 1.22), less vegetable consuming (OR 1.59) and more obese (OR 1.46, 95%CI 1.24~1.73) compared to the others. CONCLUSION: TV viewing and computer use were associated with several obesity related lifestyles in children.

Standardization of the Korean Version of Patient Health Questionnaire-9 as a Screening Instrument for Major Depressive Disorder

BACKGROUND: Depression is the most frequently encountered mental disorder in primary care. In it is necessary to order to, have a screening tool has high sensitivity and specificity and consumes less time. Therefore, the aim of this study was to assess the validity of the Korean version of Patient Health Questionnaire-9 (PHQ-9). METHODS: A convenience sample of 160 ambulatory patients in a family practice clinic at Inha university hospital and the health care center at Bakae hospital received the Korean version of PHQ-9. Then the subjects were interviewed by a resident of family medicine according to DSM- IV criteria. The sensitivity, the specificity, the likelihood ratio, the ROC curve, the validity and the reliability of the Korean version of PHQ-9, and the consumptive time were examined. RESULTS: There were 22 pationts in the depression group and 138 in the non-depression group. The Cronbach's alpha was 0.852. The sensitivity and the specificity were 81.8% and 89.9%, respectively, and the positive likelihood ratio was 8.10. The area under curve had an excellent value, 0.944 (P<0.05). The consumptive time was 2.66+/-1.13 minutes. CONCLUSION: The Korean version of PHQ-9 hay a good reliability and validity, less consumptive time, and easy calculating score. Therefore, the Korean version of PHQ-9 seems to be a useful measure for detecting depression in primary care.
