Prevalence, Risk Factors and Primary Prevention of Osteoarthritis in Asia: A Scoping Review

Abstract

Introduction: Osteoarthritis (OA) is estimated to be the eleventh leading cause of disability worldwide. In Asian countries, OA is much less well-known than in the caucasian population and strongly associated with aging. Therefore, this article focuses comprehensively on the prevalence, risk factors and primary prevention for OA identified in Asian countries.
 
 Methods: This scoping review used the methodological framework by Arksey and O'Malley (2005). Pertaining to this topic, a comprehensive search on academic journals published from 2008 to 2018 (English) was conducted.
 
 Results: A total of 30 studies were selected in this review from 221,510 studies screened from electronic databases. The overall prevalence of OA is in a range of 20.5% to 68.0%. Most of the Asian populations reported to have knee OA in a range of 13.1% to 71.1% in various Asian countries. Risk factors that have been associated with OA are advanced age, being the female and obesity. Osteoporosis, higher body mass density, low level of education, family history of OA, smoking and environmental factors appeared as significant risk factors for OA. A strategic method of primary prevention for OA through lifestyle modification is reducing obesity and treating concomitant cardiovascular disease.
 Conclusion: Determining OA prevalence and risk factors will provide important information for planning future cost-effective preventive strategies.

Prevalence, risk factors, and health seeking behavior for knee osteoarthritis among adult population in rural Jammu – A Community based Cross Sectional Study

“…This was in tune with other studies. [ 16 17 18 19 ] Those with a positive history of knee trauma had 3.5 times higher odds as compared to those having no history of trauma in our study. MK Sasidharan et al .…”

Efficacy of a Combined Periarticular and Intraosseous Multimodal Analgesic Injection Technique in Simultaneous Bilateral Total Knee Arthroplasty: A Randomized Controlled Trial

“…The main limitation of our research was the strong female predominance in the study group, which is probably due to the tendency for Asian females to have sedentary lifestyles and high BMI [ 24 ]. A study by Matilde et al found that women reported significantly higher postoperative pain after TKA than their male counterparts, and the influence of our demographic data therefore has to be taken into consideration.…”

Cost-Effectiveness of Glucosamine in Osteoarthritis Treatment: A Systematic Review

“…These results demonstrated that women were more likely to suffer from OA than men. Additionally, another study showed that the range for the prevalence of OA is 20.5% to 68.0%, and in several Asian countries, the majority of the Asian inhabitants reported having knee OA in a range from 13.1% to 71.1% [ 8 , 20 ]. Risk variables such as age, sex (specifically female), and obesity have been linked to OA.…”

“…Risk variables such as age, sex (specifically female), and obesity have been linked to OA. Other significant risk factors for OA include osteoporosis, higher body mass density, muscle function, ethnicity and race, genetics, low levels of education, family history, smoking, lifestyle, and environmental variables [ 17 , 19 , 20 ].…”
