본 연구의 목적은 무릎관절염 환자를 대상으로 탄력밴드활동에 따른 건강관련 근력과 정량적 감각의 변화를 알아보고자 실시하였다. 무릎관절염 환자20명을 대상으로 대조군과 실험군으로 각각 10명씩 할당하여 건강관련 근력은 무릎관절 신전력을 측정하였고, 정량적 감각평가 중 감각역치는 냉감역치와 온감역치, 통증역치는 냉통증역치, 온통증역치를 측정하였다. 중재 전과 중재 후에 그룹 내 및 그룹간 변화량을 비교 · 분석하였다. 중재 후 평가를 통하여 다음과 같은 결과를 얻었다. 실험군은 대조군에 비해 무릎관절 신전력, 냉감역치 및 냉통증역치는 통계학적으로 유의하게 향상되었으며, 온감역치와 온통증역치는 통계학적으로 유의하게 감소되었다. 이러한 결과는 탄력밴드활동을 통해 신전력이 증진되는 과정에서 체성감각이 충분히 자극되었고, 이러한 자극이 체표면의 혈류량을 증가시켜 피부온도를 상승시킴으로써 냉감역치와 냉통증역치를 증가시키고, 온감역치와 온통증역치는 감소시키는 것으로 판단되며, 향후 무릎관절염 환자의 근력 및 정량적 감각의 향상을 위해 파트너를 이용한 밴드운동이 가정운동프로그램으로 처방 및 활용이 고려되어야 한다고 사료된다. The purpose of this study was to analyze the changes of the quantitative sense and muscle strength after elastic band activity with a partner in patients with knee arthritis. 20 patients with knee osteoarthritis were grouped in a control and experimental group, 10 in each group. For the related muscle strength, the knee joint extensor was measured and for the quantitative sensory evaluation, cold sensation threshold, warm sensation threshold, cold pain threshold, and heat pain threshold were measured. The results showed statistical significance between the experimental group and the control group in all measurements (quantitative sensory evaluation and related muscle strength). The elastic band activity has a positive impact on the increase of related muscle strength and quantitative sense of knee osteoarthritis patients.

근로자의 요통으로 인한 의료보험 이용 실태를 파악하기 위해 1993년부터 1995년까지 광주의 한 직장 의료보험조합에 소속된 남자 8,783명, 여자 1,400명계 10,153명의 의료보험 급여자료로부터 한국표준질병사인 분류코드상 요통과 관련된 변형성 배병증, 기타 배병증, 요추염좌에 해당되는 질환군의 치료시 이용한 의료보험 급여자료와 연구대상자의 일반적 특성을 결합시켜 분석한 결과는 다음과 같다. 1. 1993년부터 1995년까지 3개년간 연구대상자의 요통으로 인한 수진율은 남자 17.1%, 여자가 19.4%였으며, 요통의 원인중 남녀 모두 '기타 배병증'이 가장 많은 비율 차지하였다. 2. 남녀 모두에서 연령 및 입사시 연령이 높을수록 요통으로 인한 수진율이 증가하는 경향이 있었다(p<0.001). 남녀 모두 근무기간이 길수록 수진율이 증가하는 경향을 보였으나, 통계적 유의성은 없었다. 남자에서는 시멘트 콘크리트제품 제조업 종사자가 유의하게 수진율이 높았으며(p<0.01), 여자에서는 생산직이 사무직보다 유의하게 높았다(p<0.01). 3. 1993년부터 1995년까지 3개년간 요통의 수진율과 요통으로 인한 새로운 수진자의 발생율은 비슷하였지만, 세부적으로 남녀 모두에서 기타 배병증이 증가하는 경향이 있었다. 4. 수진량에 있어서는 연령별, 근무기간별, 산업별, 소득수준에 따라 수진자 1인당 평균외래수진건수에 있어서 유의한 차이가 있었고(p<0.05), 근무기간별로 수진자 1인당 평균외래방문회수가 유의한 차이를 보였다.(p<0.05). 이상을 종합해보면 매년 요통으로 인한 의료보험 이용자수가 증가하고 있으며, 특히 만성적인 장애를 유발하는 추간판탈출증을 포함하고 있는 '기타 배병증'이 현저하게 증가하고 있는 경향을 볼 때 산업장에서 효과적인 요통예방 및 관리 사업이 요구된다 하겠다. To find the medical insurance utilization of workers when suffering from low back pain, an analysis was made toward the data of medical insurance benefits matched with the general characteristics of 10,183 workers, who were registered continuously from 1993 to 1995 at a medical insurance cooperation for industrial workers. The results were as follows; 1. The period prevalence of the medical insurance utilization for low back pain for 3 years from 1993 to 1995 was calculated as 17.1% for male workers and 19.4% for female workers. Most common cause of utilization was other dorsopathies including the herniation of lumbar discs. 2. The utilization rate increased significantly as the present age and the age joining the company got older(p<0.001). As the duration of employment got longer, the utilization rate of the male showed the tendency to increase and that of the female increased significantly(p<0.05). Among male workers employed at cement and concrete manufacturing companies showed higher utilization rate and among female laborers showed significantly higher utilization rate than clerical workers(p<0.01). 3. Annual utilization rate for low back pain didn't show any difference, but the portion of other dorsopathies among cause of utilization showed the tendency to increase from 1993 to 1995. 4. The mean number of claims for outpatient medical care for low back pain differed significantly by age, working duration, type of industries, income level(p<0.05), and the mean of total visiting days for care of low back pain differed significantly by working duration. In conclusion, considering the fact that the medical insurance utilization for low back pain increased annually and other dorsopathies including the herniation of dorsopathies were increasing, an effective preventive or management program for low back pain toward worker employed at industries were required.

This study was conducted to evaluate the association of work posture with cervical spine abnormality toward 106 microwave-oven assemblers. A self-administered questionnaire was used to obtain a general characteristics and a work history of workers. The posture of neck and shoulder joint of workers were measured with video tape recording and the simple X-ray of cervical spine was checked-up to observe the X-ray abnormality including degenerative change, curvature abnormality, disc space narrowing or disc canal narrowing. The result were as follows. 1. The prevalence of degenerative change among cervicobrachial disorder workers was 44.3% (47 persons), curvature abnormality was 43.4%(46 persons), disc space narrowing was 21.7%(23 persons), and disc canal narrowing was 21.7%(23 persons). 2. The prevalence of degenerative change at cervical spine was increased with the degree of neck flexion(flexed versus neutral, odds ratio [OR]=2.7), the total work posture of neck(mild or severe awkward versus neutral ; OR=1.2, 3.4). 3. The prevalence of degenerative change at cervical spine was increased with the degree of the right shoulder flexion, the heaviness of the materials carried by the right hand and the degree of awkwardness at the total work posture of right shoulder(p<0.05). 4. There was no evidence of association between curvature abnormality, disc space narrowing, disc canal narrowing and work posture. In conclusion the awkward work posture was related with degenerative change of cervical spine among microwave oven assembling workers and the further study in these field must be made to prove the association objectively.

This study was performed to find the prevalence and the associated risk factors with low back pain(LBP) of the staffs in a university at Kwang-ju city. The data were collected by a questionnaire including SDS(self - rating depression Scale) battery from September 1st to October 15th, 1996. The results were as follows; 1. The prevalence rate of LBP during lifetime was 73.1%, 53.1% for the last one year, and 23.6% for the last one week. 2. Statistically significant factors related to LBP during lifetime were sex and satisfaction with job. Sex, smoking, alcohol drinking, occupation, work posture, forward bending of trunk and satisfaction with job were selected as significant factors related to LBP during the last one year. The significant determinants related with LBP during the last one week were sex, smoking, alcohol drinking, occupation, forward bending of trunk and satisfaction with job. 3. Through the analysis of self - rating depression scores according to LBP, respondents with LBP had the significantly higher value of physiological disturbances and lower value of psychomotor activities than those without LBP. 4. Through the multivariate logistic regression, significantly associated factors with LBP during lifetime were selected to be female(OR=2.63, 95% CI : $1.08\sim6.40$), dissatisfaction with job(OR=2.16, 95% CI : $1.16\sim4.15$), those for the last one year were chosen to be female(OR=2.30, 95% CI : $1.03\sim5.12$), forward bending of trunk(OR=2.18, 95% CI : $1.26\sim3.79$), dissatisfaction with job(OR=1.84, 95% CI : $1.06\sim3.21$), and those for the last one week were female(OR=3.00, 95% CI : $1.17\sim7.69$), forward bending of trunk(OR=2.85, 95% CI : $1.38\sim5.88$). In conclusion, for effective prevention of the LBP at work site, appropriate improvement of work posture and various psychological factors should be considered.

Objectives : This study was peformed to assess the association between the social support and blood pressure(BP) in a rural community. Methods : A cross-sectional survey, comprising a health examination including BP, height and weight and a questionnaire-based interview which investigated social support, demographic factors, smoking, drinking, and etc. was peformed between February 10th and March 5th, 1998. The survey included 318 persons who were over than 30-year-old in the rural community of Kwangju, Republic of Korea. We excluded persons who taking antihypertensive medications or who provided incomplete information; we subsequently analyzed the data from 284 persons. In order to test the hypothesis of an association between BP and social support controlling confounders such as age, educational level, working time, body mass index, smoking and drinking, the data was analyzed using multiple linear regression analysis. Results : The subjects were composed of 109(38.4%) males and 175(61.6%) females with mean ages of 62.0 years and 61.1 years, respectively. The hypertension prevalence was 41.3% among males and 45.1% among females. In the correlation analysis, higher total social support scores correlated significantly with lower systolic BP in both males and females. The hypertension prevalence increased significantly with the decreasing of the social support in males. In multiple regression analysis, systolic and diastolic blood pressure showed a negative association with social support in both males and females, although this was not statistically significant. Conclusions : Larger and broader studies are required in the future in order to identify the association between the social support and BP.

Objectives : To investigate the relationship of serum uric acid to cardiovascular risk factors in Korean male workers. Methods : We screened 522 male workers at an electrical manufacturing company by a periodic health examination and a questionnaire survey in 2000. We collected data relating to age, smoking status, alcohol drinking status, body mass index (BMI), blood pressure, serum lipid, fasting blood glucose and serum uric acid. The data were analyzed using a variety of methods, including ANOVA, Pearson's correlation, and multivariate regression analyses. to examine the association between uric acid and cardiovascular risk factors with a cross-sectional study design. Results : The concentration of serum uric acid showed positive associations with BMI, total cholesterol, triglyceride, and LDL-cholesterol; it was also significantly correlated to systolic and diastolic blood pressures. Life-style characteristics, such as smoking and alcohol drinking showed no significant association. From the multivariate regression analyses, BMI, total cholesterol and fasting blood glucose levels were found to be independent positive predictors of uric acid; while age, blood pressure and smoking status give no independent contribution explaining the variability of serum uric acid levels. Conclusions : This study demonstrates that serum uric acid level have a significant association with cardiovascular risk factors, such as BMI, total cholesterol and blood glucose in some Korean male workers.

목 적: 6~7세 소아에서 영양섭취상태와 비만, 혈압, 혈중 지질 농도 등을 조사하여 비만의 예방과 치료에 필요한 정보를 얻고자 본 연구를 시행하였다. 방 법: 2007년 9월부터 10월까지 광주광역시와 전남지역의 3개 초등학교 1학년 483명(남아 233명, 여아 250명)을 대상으로 하였다. 체중, 신장, 비만도 및 BMI, 혈압, 맥박 등 신체를 계측 하고 공복 시 지질, 혈당등 생화학적 검사를 시행하고, 부모가 작성한 설문지를 통해 각 아동들의 영양 상태를 평가 하였다. 결 과: 1) 비만은 9.9%이었으며 남아에서 10.3% (경도 4.7%, 중등도 이상 5.6%), 여아에서 9.6% (경도 6.4%, 중등도 이상 3.2%)이었다. 성별에 따른 차이는 없었다. 반면 12%에서 영양 부족을 보였다. 평균 총 칼로리 섭취량은 남아, 여아에서 각각 1,781 kcal, 1,640 kcal이었으며 각각 35% 이상, 30%에서 권장량 이상을 섭취하고 있었으나 성별에 따른 유의한 차이는 없었다. 이상지질혈증은 총 콜레스테롤이 200 mg/dL 이상인 경우 8.4%이었으며, LDL 콜레스테롤이 130 mg/dL 이상인 경우 3.1%이었다. 중성 지방이 130 mg/dL 이상인 경우 5.0%였고, HDL 콜레스테롤이 낮은 경우는 4.4%였고, 동맥경화지수가 4.0 이상인 경우는 12.1%였다. 2) 비만정도에 따라 수축기 혈압, 중성 지방, LDL 콜레스테롤이 유의한 차이가 있었으며 총 섭취 열량과 영양구성과는 상관관계가 없었다. 3) 비만도에 따라 중성지방, LDL 콜레스테롤, 동맥경화지수에서 이상지질혈증 발생률이 유의하게 높은 상관관계가 있었다. 4) 고혈압은 2.1%에서 나타났으며 혈압군에서 BMI, 중성지방이 유의하게 높았다. 5) BMI는 혈압, LDL 콜레스테롤, 중성지방과 양의 상관관계가 있었으며, 비만도는 혈압, LDL 콜레스테롤, 중성 지방, 총 콜레스테롤과 양의 상관관계가 있었다. 6) BMI는 총 섭취 열량과 섭취한 영양 구성 과 상관 관계가 없었고 통계적으로 유의하기 않았다. 결 론: 6~7세에서 비만도가 높아질수록 유의하게 고혈압과 이상지질혈증의 유병률이 높았다. 따라서 6~7세에서부터 비만증과 합병증에 대한 선별검사, 관리 및 치료가 필요하다. Purpose: This study was designed to characterize the nutritional status and assess obesity to determine the relationship between obesity and serum lipid profiles in 6~7 year old children. Methods: In 2007, we surveyed 483 children (233 boys and 250 girls) aged 6~7 years. The total cholesterol, triglyceride levels and HDL-cholesterol were measured in the fasting state. Dietary information was obtained by a questionnaire. Results: The prevalence of obesity was 9.9%. There was no significant difference between genders. The mean caloric intake was 1,781 kcal in boys and 1,640 kcal in girls. The prevalence of excessive calories was 33% in boys and 30% in girls. The prevalence of a total cholesterol ${\geq}$200 mg/dL was 8.4%, TG ${\geq}$130 mg/dL was 5.0%, LDL-cholesterol ${\geq}$130 mg/dL was 3.1%, and HDL-cholesterol <35 mg/dL was 4.4%. The prevalence of hypertension was 2.1%. There was no significant difference between genders. The systolic blood pressure, triglyceride levels and LDL-cholesterol were significantly related to an increased obesity index (p<0.05). The mean caloric intake and nutritive component were not related to the obesity index. The obesity group was compared to the control group: for triglycerides ${\geq}$130 mg/dL the odds ratio was 4.08; for LDL-cholesterol ${\geq}$130 mg the odds ratio was 2.85; for a TC/HDL-cholesterol ${\geq}$4.0 the odds ratio was 1.16. The BMI and triglyceride levels in the group with hypertension were higher than control group (p<0.05). There were significant positive correlations between the BMI and blood pressure as well as the LDL-cholesterol and triglycerides (p<0.05). The BMI was not correlated with the mean caloric intake or nutrition. Conclusion: The prevalence of hypertension and hyperlipidemia in 6~7 year old children was significantly related to an increased obesity index. The management of obesity in 6~7 year old children should include a reduction in the risk for hyperlipidemia and hypertension.
