Abstract

Objectives: This study was performed to investigate the prevalence of knee osteoarthritis according to the criteria of diagnosing knee osteoarthritis in rural women and the factors related with this disease. Methods: The data obtained from 200 women older than 40 years of age residing in 5 Ri's in Goryeong-gun. Gyeongsanbuk-do by random cluster sampling from September to October 2002. Knee osteoarthritis was determined positive according to the Kellgren and Lawrence classification and knee pain. Results: Among these subjects, 71.0% showed more than grade 2 in radiologic finding and the rate of knee pain according to the survey was 67.0%. The rate of subjects meeting the criteria of knee osteoarthritis was 54.0%. According to univariate analysis, the prevalence of knee osteoarthritis increased with age and those farming people and people working in household industry was significantly high at 58.9% compared with others. The prevalence of knee osteoarthritis showed a significant relationship with the family history and past history of knee injury and knee surgery(p<0.01), and diabetes mellitus(p<0.05). The score of ADL was significantly different in the subjects with knee osteoarthritis compared with normal group(p<0.05). When the presence of knee osteoarthritis and the period of the life style of seating down on the floor were compared, a significant difference was present between the osteoarthritis group and normal group. As for metabolic factors, the blood sugar level, bone density, and body mass index(BMI) were significantly different in the osteoarthritis group compared with normal group. When multiple logistic regression analysis was performed with the presence of knee osteoarthritis as the dependent variable, the prevalence of knee osteoarthritis was significantly affected by older age, subjects farming or working in household industry, the history of knee injury, the history of surgery, higher blood sugar level, and higher BMI. Conclusions: These subjects need an intervention through self-care programs such as exercise for preventing osteoarthritis, weight control programs, other exercise programs strengthening knee joints, and guidelines when working in vinyl houses.

지역사회 주민들을 대상으로 무릎 골관절염 진단기준을 적용하여 무릎 골관절염의 유병률을 파악하고, 관련요인을 규명하기 위하여 2002년 9월부터 10월까지 무작위 집락표본추출에 의하여 경상북도 고령군의 5개리에 거주하는 조사 가능한 40세 이상 여성 258명 중 200명을 조사완료(77.5%)하여 분석하였다. 대상자의 일반적 특성과 질병 과거력, 가족력, 건강행위, 좌식생활 형태 및 일상생활 수행능력 등은 설문조사를 하였으며, 신체계측과 혈압, 혈당, 혈중 총 콜레스테롤, 골밀도를 측정하고 무릎 X-선 촬영을 하였다. 자료분석은 SPSS 10.0을 이용하여 빈도분석, 카이제곱검정, t-검정, 다중로지스틱회귀분석을 시행하였다. 골관절염 양성의 기준이 되는 Kellgren과 Lawrence 분류법에 의한 등급 2 이상(71%)과 설문조사에 의한 무릎 통증이 있는(67%) 기준을 충족시키는 무릎 골관절염 환자는 54%였다. 단변량 분석에서는 연령이 높아질수록 무릎 골관절염 유병률이 높았으며, 직업에 따라서는 농업이나 가내공업에 종사하는 군의 유병률이 58.9%로 기타 직업을 가진 군에 비하여 유의하게 높았다. 무릎 골관절염의 가족력과 무릎 외상 및 수술경험(p<0.01), 당뇨병(p<0.05)은 유병률과 유의한 관련성이 있었다. 신체활동도 점수는 무릎 골관절염 군이 정상군에 비하여 유의한 차이가 있었다(p<0.05). 무릎 골관절염 이환 여부에 따른 좌식생활 기간을 비교해 보면 골관절염 군이 정상군에 비해 유의한 차이가 있었다. 혈당, 골밀도, 체질량지수는 골관절염군과 정상군 간에 유의한 차이가 있었다. 무릎 골관절염의 유병 여부를 종속변수로 한 다중로지스틱회귀분석에서는 연령이 높을수록, 농업이나 가내공업에 종사할수록, 관절외상 및 수술경험이 있는 경우에 혈당이 높을수록, 체질량지수가 높을수록 무릎 골관절염 유병률에 유의한 영향을 미치는 것으로 나타났다. 골관절염 관리를 위한 자조운동과 체중조절, 통증관리를 위한 물리치료 등의 조절가능 인자에 대한 중재를 위한 자조교실과 같은 접근 가능한 자기관리와 골관절 운동프로그램을 확대하고 비닐하우스 작업시 자세에 대한 가이드라인 등의 제시가 필요하다고 생각한다.
