INTRODUCTION
Osteoarthritis knee is one of the most prevalent conditions of knee in elder age group of population. Its causes pain, disability in geriatric population of society. Longer life expectancy is responsible for increase in osteoarthritis knee. K-L scale is well known scale of radiographic OA knee. This study was done to find prevalence of OA knee in Indian population of older than 40 years using K-L scale.
METHOD
The study was a community based cross sectional study. The target population was from 5 metropolis, 5 cities near the metropolis, 5 towns and 20 villages from blocks of these towns. i.e. 5 sample groups were covered. Sample size n = 4680 which was further divided into 5 sites equally (936 from each site). This was rounded to a sample of 1000 from each site. This evaluation study was conducted using the household as the primary sampling unit for the quantitative survey. The respondents for the study were above 40 years. Quantitative data was collected using structured questionnaire and X-Ray Investigation. OA was graded using the Kellgren and Lawrence scale. Data analysis was performed using SPSS statistical software. Frequencies and percentages were calculated to find the prevalence of OA. Chi-Square test was used to find the association of OA with various factors.
RESULTS
The present study shows a prevalence of 28.7% of OA in the overall sample. This varies slightly in the individual states - Agra (35.5%), Bangalore (26.6%), Kolkata (33.7%), Dehradun (27.2%), and Pune (21.7%).OA prevalence was found to be more in participants who used western toilet (42.1%), in sedentary people (82.9%), in females and in obese.
CONCLUSION
This study has evidenced that there is a large percentage of sub-threshold population. i.e. K-L grade 1 which is considered as border-line or doubt-full as far as OA diagnosis. Awareness of OA should be initiated at community level, which is needed for prevention of OA at early age.
引言
膝骨关节炎是老年人群中最常见的膝关节疾病之一。它会导致社会老年人群疼痛和残疾。预期寿命的延长导致膝骨关节炎发病率上升。K-L量表是众所周知的膝关节放射学骨关节炎量表。本研究旨在使用K-L量表确定印度40岁以上人群中膝骨关节炎的患病率。
方法
该研究是一项基于社区的横断面研究。目标人群来自5个大都市、大都市附近的5个城市、5个城镇以及这些城镇街区的20个村庄。即涵盖了5个样本组。样本量n = 4680，进一步平均分为5个地点（每个地点936人）。每个地点取整为1000人的样本。本评估研究以家庭作为定量调查的主要抽样单位。研究对象为40岁以上人群。使用结构化问卷和X线检查收集定量数据。骨关节炎采用Kellgren和Lawrence量表分级。使用SPSS统计软件进行数据分析。计算频率和百分比以确定骨关节炎的患病率。采用卡方检验确定骨关节炎与各种因素的关联。
结果
本研究显示总体样本中骨关节炎患病率为28.7%。在各个邦略有差异——阿格拉（35.5%）、班加罗尔（26.6%）、加尔各答（33.7%）、德拉敦（27.2%）和浦那（21.7%）。发现使用西式马桶的参与者（42.1%）、久坐人群（82.9%）、女性和肥胖者的骨关节炎患病率更高。
结论
本研究证明存在很大比例的亚阈值人群。即K-L 1级，就骨关节炎诊断而言，这被视为临界或可疑。应在社区层面提高对骨关节炎的认识，这对于早期预防骨关节炎是必要的。
