  • This study has been attempted to be helpful for the back rehabilization of Korean workers by analyzing the general, occupational, social aspects of low back pain and to identify possible risk factors for back pain in White and Blue collar workers. The primary data were collected from 380 workers in Seoul city by means of a Questionnaire with random which was distributed from March 10 to 31, 1990. For the test of statistical significance, chi-square analysis was used to compare the back pain characteristics between above two groups. The results were as follows : 1. The incidence of low back pain in all walkers studied was $79.7\%$. The incidence of Blue collar with low back pain $(87.2\%)$ was higher than that of White collars $(75.0\%)$. 2. With regard to the relationship of back pain to the occupational characteristics, statistically significant differences were observed between workers with and without back pain concerning the job factors on work-time, job satisfaction, mental stress, chair fittness, work posture, work rotation, weight lifting, monotonous repetitive movements, vibration, and heavy noise (p<0.05). 3. With regard to the relationship of back pain to the social characteristics, there were no differences with respect to having car, personality types, drinking habits, and leisure-time activities. However, significant differences were showed between no pain and pain groups for the using bed, sleeping posture, traffic time amount, walking health state, smoking habits, and physical exercise (p<0.05). 4. The comparative analysis of back pain related to work factors showed highly significant differences with respect to mental stress, chair fittness, work posture, trunk rotation, weight lifting, monotonous repetitive work in White collar group (p<0.01) ; and job satisfaction, mental stress, trunk rotation, weight lifting, monotonus repetitive work, exposure to vibration and heavy noise in Blue collar group(p<0.01). 5. The comparative analysis of social factors in two groups showed differences with respect to the using bed, sleeping posture, walking amount, health state, physical exercise, smoking habits in White cellar group (p<0.05) ; and walking amount, traffic time amount, health state, smoking habits, physical exercise in Blue cellar group (p<0.05). 6. In regard to the general aspects of back pain between two groups, there were differences concerning etiolgy of back pain, counselling partners, treatment types, and sick-leaves(p<0.05), except pain duration, and awareness of back pain.

  • Purpose: Abrupt abstinence from alcohol in cause of chronic alcohol addiction can trigger alcohol withdrawal syndrome. The authors studied the effect of post-operative alcohol withdrawal syndrome in patients who require intensive care due to trauma. Methods: For the study group, we selected 70 patients who had undergone emergency surgery from May 2003 to March 2007 due to trauma and who had been treated with prophylactic thiamine. Data was collected retrospectively. We excluded those who extended their hospital stay for other than traumatic causes, those who died within 3 days of surgery after trauma, those who transferred to other institutions, and those who received a psychiatric diagnosis. Patient groups were determined by the existence or the non-existence of withdrawal syndrome. Age, sex, injury mechanism, mortality, complications, durations of hospital stay and intensive care, use of mechanical ventilator, and sedative use were investigated. A Chi-square test and The Mann-Whitney method were used for statistical analysis in this study. Results: Twenty-four (24) patients from the 58 who had an ISS of 16 or more showed alcohol withdrawal syndrome, and men were shown to be affected with the syndrome significantly more than women. Although ISS was higher in the group with alcohol withdrawal syndrome, statistically, the difference was not significant (P<0.08). The total hospital stay in the patient group with alcohol withdrawal syndrome was on average 10 days longer. However, the difference was not significant (P<0.054). The duration of intensive care in the patient group with alcohol withdrawal syndrome was significantly longer (P<0.029). The patients with alcohol withdrawal syndrome showed no significant difference in the duration of mechanical ventilator use (P<0.783), or in the duration of sedative use (P<0.284). Respiratory distress, pneumonia, upper airway infection, sepsis, acute renal failure, and mortality in the alcohol withdrawal syndrome group were investigated, but no statistically significant difference were noted. Conclusion: We found that the duration of intensive care in chronic alcohol abusers was longer due to the development of alcohol withdrawal syndrome. We also discovered that, when the patients overcame the symptoms of alcohol withdrawal syndrome after intensive care, no difference was found in the frequency of developing complications, the morbidity, and the mortality. Therefore, we conclude that intensive care in trauma patients who are chronic alcohol abusers decreases the incidence of complications found in patients with post-operative alcohol withdrawal syndrome and does not adversely impact the prognoses for those patients.

  • Purpose: Few studies have been done for spinal injuries after skiing and snowboarding accidents. Assuming that the riding patterns of skiing and snowboarding were different, we analyzed the differences between the mechanisms, diagnoses and levels of spinal injuries caused by them. The purpose of this study was to gain a better understanding of spinal hazards associated with skiing and snowboarding in order to educate skiers and snowboarders. Methods: We conducted a prospective study of 96 patients who had sustained spinal injuries as a result of skiing and snowboarding accidents from January 2003 to March 2006. We used a questionnaire, radiological studies, history taking, and physical examinations. We analyzed the mechanism of injury, the level of spinal injury, the severity of spinal injury, and the Abbreviated Injury Scale scores (AIS score). We used the t-test and the chi-square test. Results: The skiing and the snowboarding injury group included in 96 patients. The skiing injury group included 30 patients (31.2%), and the snowboarding injury group included the remaining 66 patients (69.8%). The primary mechanism of injury in skiing was collisions and in snowboarding was slip downs (p=0.508). The primary level of spinal injury in skiing and snowboarding was at the L-spine level (p=0.547). The most common athlete ability of the injured person was at the intermediate level (p=0.954). The injured were most commonly at the beginner or the intermediate level (p=0.302). The primary diagnosis of spinal injury in skiing and snowboarding was back spain (p=0.686). The AIS scores did not differed between the two groups (p=0.986). Conclusion: The most common spinal injury after skiing and snowboarding accidents was back sprain. There was no difference in the severity of spinal injury between skiing and snowboarding accidents.

  • Objectives : The amount of medical utilization by Medical Aid recipients was 3.7 times that of patients with Korean Medical Insurance. This study aims to describe the surplus medicine and the medication-related utilization, and to determine factors contributing to surplus medicine. Methods : Among those who used copayment-free Class I Medical Aid in 2005, 146,880 subjects who were $\geq19$ year-old and received >365 days medical treatment per year were studied with their case managers by conducting face-to-face interviews. The analytic methods were description, chi-square, t-tests, ANCOVA and multiple logistic regressions. Results : Most subjects were female (68.6%), the elderly (62.5%), and the separated (61.6%), had an elementary graduation or less (74.8%), and had disabilities (33.2%). The percentage of subjects with surplus medicine was 18.5%. However, the percentage of females, the elderly, those with non-disabilities, the separated, the uneducated, those with a very poor perceived health status and those with an economical burden for medical treatment was 19.3%, 18.9%, 19.0%, 19.3%, 19.0%, 20.2% and 24.3%, respectively. For subjects with surplus medicine, averages for the number of used pharmacies, the pharmacy-visit days and the medication costs were 4.6 drugstores, 34.9 days and approximately 1,124 thousand Won(₩). These values were higher than those without surplus medicine (4.4 drugstores, 33.8 days, and ₩1,110 thousand, respectively). The odds ratios of the contributing factors to surplus medicine were female 1.11 (95% CI=1.07-1.14), the elderly 1.06 (95% CI=1.02-1.10), those with non-disabilities 1.08 (95% CI=1.05-1.12), the separated 1.14 (95% CI=1.10-1.18), the unmarried 1.12 (95% CI=1.07-1.18), the uneducated 1.03 (95% CI=1.01-1.08), those with a very poor perceived health status 1.04 (95% CI=1.01-1.08) and experiencing an economical burden for medical treatment 2.33 (95% CI=2.26-2.40). Conclusions : 18.5% of subjects had surplus medicine with a higher mean of medication cost. Therefore, health education and health promotion programs to prevent surplus medicine and to improve the appropriate usage of medication are necessary.

  • Background: The aim of the current study was to investigate the factors related to the non-practice of cancer screening in cancer survivors, who are at high risk of developing second cancers. Methods: This study is a cross-sectional analysis of 1,125 cancer survivors ${\geq}19$ years old who participated in the Korean National Health and Nutrition Examination Surveys IV and V (2007-2012). A Rao-scott chi-square test and a survey logistic regression analysis were employed respectively to analyze the difference of cancer survivors in cancer screening by each characteristic and the factors related to the non-practice of cancer screening in cancer survivors. Results: Among total subjects, 33.5% did not participate in cancer screening in the last two years. Results from a fully adjusted logistic model showed that the non-practice of cancer screening in cancer survivors was significantly associated with variables such as sex, age, marital status, education level, monthly income, and drinking a alcoholic beverage Specifically, the odds ratio of non-practice of cancer screening was higher in males than in females, in the younger group than in older group, in the group with no spouse than in the group with a spouse; in a group with a low level of education than in a group with a high level of education; in a group with the lowest income level than in a group with the other levels of income; or in non-drinkers than in drinkers. Conclusion: Health policies to reduce the non-practice rate of cancer screening in cancer survivors should be designed and implemented with close attention to cancer survivors' socio-economic characteristics such as sex, age, marital status, education, and income, along with a health behavioral characteristic as drinking.

  • Background: Both objective body shape and perceived body image have been known to influence the mental health. The purpose of this study was to explore the relationship of a combination between actual body mass index (BMI) status and perceived body image with anxiety depressive condition (ADC) in Korean men and women. Methods: This cross-sectional study analyzed data of 26,239 subjects ${\geq}20$ years old from the National Health and Nutrition Examination Survey (2010-2014). This study performed a Rao-Scott chi-square and multivariate logistic regression analyses reflecting survey characteristics and used a variety of independent variables such as socio-demographics and health behavior factors. Results: With all independent variables considered, people with normal weight who perceived themselves as overweight were more likely associated with ADC than a referent group with normal weight who perceived themselves as normal weight, as shown for both men (odds ratio [OR], 1.52; confidence interval [CI], 1.07-2.15) and women (OR, 1.25; CI, 1.06-1.48). Meanwhile, compared to the referent group, men with underweight who perceived themselves as underweight showed a lower association with ADC (OR, 0.63; CI, 0.41-0.97), whereas women with underweight who perceived themselves as underweight showed its higher association (OR, 1.47; CI, 1.10-1.96). Conclusion: A certain group of people categorized as a combination between actual BMI status and perceived body image showed a relatively high likelihood of having ADC, and the gender difference in the likelihood of having the condition for a group was clear. Therefore, this study suggests the need to identify the group at a high risk of ADC on the basis of actual BMI status and perceived body image and to develop an appropriate mental health management program for the group.

  • WTO 출범 이후 우리나라 국민의 식생활 중 수입식품이 차지하는 비중이 급속히 늘어나면서 수입식품 자체의 위해성과 수입농산물에 관한 지식이나 정보가 소비자들에게 부족하여 올바른 구입과 소비가 어렵게 되어 피해를 당하는 경우도 발생하고 있다. 본 연구에서는 청주지역 주부들을 대상으로 수입식품 이용과 인식도 및 수입식품 분별능력의 조사를 통하여, 교육의 필요성여부를 검토하였다. 조사 대상자는 청주시에 거주하는 주부 183명이었고, 조사기간은 2003년 3월 1일부터 3월 15일까지였다. 조사내용은 조사대상자의 일반사항, 식품구입시 태도, 수입식품 구입 경험, 수입식품에 대한 인식도, 수입식품과 국산식품의 분별력 테스트로 구성되었으며, 인식도는 5점 척도에 의해 조사되었다. 사용된 통계처리 방법은 SAS program을 사용하여 빈도, 백분율, 평균, 표준편차를 구하였고, Chi-square 또는 ANOVA로 검정하였다. 연구결과는 다음과 같다. 국내산과 수입산 표시의 확인여부는 응답자의 92.3%가 확인한다고 응답하였고, 선호도를 조사한 결과 99.5%가 국내산을 선호하는 것으로 나타났다. 선호하는 주된 이유로는 ‘수입산은 유해물질이 많으므로’라는 응답이 46.3%로 가장 많이 나타났고, 수입식품 구입경험의 유무로는 92.3%가 경험이 있다고 응답하였으며, 구입동기에 대해 ‘수입산이 시중에 많아 쉽게 구입할 수 있기 때문에’라는 응답이 61.6%로 가장 많았다. 또한 수입식품을 국산식품으로 혼동하여 구입한 경험으로는 응답자의 76%가 ‘있다’고 응답하였으며 혼동한 이유로는 ‘수입식품과 국산식품의 구분이 명확하지 않아서’ 49.6%, ‘수입산과 국내산의 표시가 명확하지 않아서’ 41%를 차지했다. 국내산과 수입산 표시에 대한 신뢰도는 89.7%가 대체로 신뢰하지 않는 것으로 나타났다. 신뢰하지 않는 이유로는 ‘허위표시에 대한 보도를 많이 접해서’가 56.l%로 가장 많은 비율을 차지했다. 수입식품의 인식도를 품질, 가격, 포장 용기, 맛, 조리편리성, 안전성, 건강에 미치는 영향의 7가지 측면에서 살펴보았는데, 수입식품의 품질과 맛에서 국내산과 비슷하거나 나쁘다고 인지하였고, 가격은 수입식품이 싸다고 인지하고 있었으며 연령과 유의성을 보였다(p <0.01). 포장 용기와 조리편리성에 대해서는 국내산과 비슷하거나 좋다고 인지하고 있었으며, 조리편리성은 학력과 유의성이 높게 나타났다(p < 0.01). 안전성과 건강에 미치는 영향에 대해서는 나쁘다고 인지하고 있었다. 수입식품과 국산식품의 분별정도는 66.1%가 구별하는 능력이 언다고 응답하였다. 분별정보를 얻는 경로로는 ‘TV 및 라디오 프로그램’이 61.7%로 가장 많았다. 수입식품에 관한 교육을 받을 의향에 있어서 61.5%가 ‘예’라고 응답하였고, 필요한 교육에 대해 ‘국산식품과 수입식품의 분별법에 관한 내용’이 75.4%로 가장 많았다. 수입식품 분별력 테스트에 있어서는 40점 만점에 평균이 13.6 $\pm$ 7.4점으로 낮았고, 분별력이 가장 좋은 품목은 고사리(53.6%), 분별력이 가장 낮은 품목은 고춧가루(40.4%)로 나타났다. 분별정도에 있어서 ‘매우 잘 구별한다’고 응답한 사람일수록 분별력 점수가 높게 나타나 주부들이 자신의 분별능력에 대해 매우 잘 인지하고 있다는 것을 알 수 있었다(p<0.001). 이상의 결과를 통하여 대부분의 응답자가 수입산에 대해 부정적인 태도를 보이고 있으나 대부분 구입경험이 있고, 분별력 점수도 낮은 편이었다. 따라서 국내 소비자들의 피해를 줄이기 위하여는 수입식품과 국내식품의 특징 및 분별법에 대한 대중매체를 통한 홍보와 이에 대한 교육의 기회가 확대되어져야 하겠다.
