Factors Influencing Knee Pain
When examining the prevalence of knee pain among different ethnic groups, various factors come into play. Two significant factors that influence knee pain are lifestyle and cultural practices, as well as genetic susceptibility.
Lifestyle and Cultural Practices
Lifestyle and cultural practices can play a role in the prevalence of knee pain among different ethnic groups. For instance, certain cultural practices, such as the "floor culture" practice common among ethnic Malays, may contribute to an increased risk of knee injuries and osteoarthritis [2]. These practices involve activities that require individuals to sit, kneel, or squat on the floor for extended periods, which can place additional stress on the knee joints.
It's important to note that lifestyle and cultural practices alone do not fully explain the ethnic disparities in knee pain prevalence. Other factors, such as genetic differences and occupational differences, also come into play when examining the prevalence of knee pain among different ethnic groups [2].
Genetic Susceptibility
Genetic factors may contribute to the differences in knee pain prevalence among various ethnic groups. While lifestyle factors and cultural practices are important considerations, genetic susceptibility also plays a role in the development of knee pain.
Studies have shown that certain ethnic groups may have a higher risk of knee pain and knee osteoarthritis symptoms compared to others. For example, ethnic Malays have been found to have an increased risk of knee pain and knee osteoarthritis symptoms compared to ethnic Chinese, even after adjusting for sociodemographic differences, non-communicable diseases, and obesity. Similarly, the increased risk among ethnic Indians compared to ethnic Chinese was associated with the presence of two or more non-communicable diseases.
While lifestyle factors and cultural practices contribute to the higher prevalence of knee pain among certain ethnic groups, genetic differences also play a role in the observed disparities. Further research is needed to gain a deeper understanding of the genetic factors that contribute to knee pain prevalence among different ethnic groups.
Understanding the influence of lifestyle and cultural practices, as well as genetic susceptibility, can help pave the way for more targeted interventions and strategies to address knee pain in different ethnic populations. By considering these factors, healthcare professionals can develop more tailored approaches to prevention, management, and treatment, ensuring that individuals from all ethnic backgrounds receive appropriate care for their knee pain.
Ethnic Variations in Knee Osteoarthritis
When examining knee pain prevalence among different ethnic groups, it becomes evident that there are variations in the occurrence of knee osteoarthritis and related symptoms.
Osteoarthritis Prevalence by Ethnicity
Studies conducted in different regions have shown varying rates of knee pain among ethnic populations. For instance, in Greater Kuala Lumpur, the prevalence of knee pain among individuals aged 55 years and older was 30.8%, with 25.4% reporting symptoms of knee osteoarthritis. Ethnic disparities were observed, with Malays reporting knee pain at 45.6%, Chinese at 21.7%, and Indians at 31.5%.
These findings align with global trends, as knee pain prevalence in older Asian populations ranges from 11% to 56%, with knee osteoarthritis being the most common cause. In the United States, ethnic variations in knee pain prevalence have also been observed, with African Americans and non-Hispanic Blacks more likely to report knee pain.
Risk Factors for Knee Osteoarthritis
While the exact reasons for ethnic disparities in knee osteoarthritis prevalence are not fully understood, various factors contribute to the increased risk among certain ethnic groups.
Lifestyle factors, such as cultural practices, have been identified as potential contributors. For example, the "floor culture" practice among ethnic Malays, which involves sitting and standing up from the floor frequently, may increase the risk of knee injuries and osteoarthritis. However, it is important to note that lifestyle factors alone do not fully explain the ethnic disparities in knee pain prevalence.
Genetic susceptibility may also play a role in the variations observed. However, further research is needed to fully understand the genetic factors contributing to knee osteoarthritis prevalence among different ethnic groups.
It is worth noting that the increased risk of knee pain among ethnic Malays compared to ethnic Chinese remained significant even after adjusting for sociodemographic differences, non-communicable diseases, and obesity. Among ethnic Indians, the increased risk was associated with the presence of two or more non-communicable diseases. These findings highlight the complex interplay of various factors in shaping ethnic disparities in knee osteoarthritis prevalence.
Understanding the ethnic variations in knee osteoarthritis prevalence is crucial for providing appropriate healthcare interventions and addressing disparities in pain management. By considering the unique risk factors associated with different ethnic groups, healthcare professionals can develop targeted strategies to prevent and manage knee pain among diverse populations.
Sociodemographic Influences
Sociodemographic factors play a significant role in the prevalence of knee pain among different ethnic groups. Educational level and occupation are two key sociodemographic influences that have been observed to have an impact on knee pain and knee osteoarthritis.
Educational Level and Knee Pain
Research suggests that individuals with lower levels of education are more likely to experience knee pain and knee osteoarthritis. A study conducted in Kuala Lumpur, Malaysia revealed that individuals with less than 12 years of education had a higher likelihood of having unilateral and bilateral radiographic and symptomatic knee osteoarthritis. In postmenopausal women, this association was partly explained by hormone replacement therapy [3].
Occupation and Knee Osteoarthritis
Occupation is another sociodemographic factor that has been linked to the prevalence of knee osteoarthritis. Certain occupations that involve repetitive movements, prolonged standing, or heavy lifting can put individuals at a higher risk of developing knee pain and knee osteoarthritis. Jobs that require frequent bending, squatting, or kneeling can also contribute to the development of knee issues.
It is important to note that the impact of occupation on knee pain can vary across different ethnicities. The same study conducted in Kuala Lumpur, Malaysia found that ethnic Malays had a higher prevalence of knee pain and knee osteoarthritis symptoms compared to ethnic Indians and Chinese. Adjustments for confounding factors such as non-communicable diseases and obesity showed that the increased risk among ethnic Malays was not fully explained by these factors [1].
Furthermore, the increased risk of knee pain and knee osteoarthritis symptoms among ethnic Indians compared to ethnic Chinese was accounted for by the presence of two or more non-communicable diseases [1]. Lifestyle factors, such as the "floor culture" common among Asians, where individuals often sit or squat on the floor, might also contribute to the increased risk of knee pain. Additionally, genetic differences have been considered as potential explanations for the ethnic disparities in knee pain prevalence [1].
Understanding the sociodemographic influences on knee pain prevalence can help healthcare professionals develop targeted interventions and strategies to address the disparities among different ethnic groups. It also emphasizes the importance of considering sociodemographic factors when assessing and managing knee pain in clinical settings.

Comorbidities and Knee Pain
When examining the prevalence of knee pain among different ethnicities, it is essential to consider the impact of comorbidities, specifically non-communicable diseases (NCDs), and obesity. These factors play a significant role in understanding the relationship between ethnicity and knee pain risk.
Impact of Non-Communicable Diseases
Research has shown that the presence of two or more non-communicable diseases (NCDs) can influence the risk of knee pain among different ethnic groups. In a study conducted in Kuala Lumpur, Malaysia, it was found that the increased risk of knee pain among ethnic Indians compared to ethnic Chinese was associated with the presence of two or more NCDs [2]. These NCDs include conditions such as hypertension, diabetes, and cardiovascular diseases.
Furthermore, the increased risk of knee pain among ethnic Malays compared to ethnic Chinese remained significant even after adjusting for sociodemographic differences, NCDs, and obesity. This suggests that factors beyond NCDs and obesity contribute to the higher prevalence of knee pain among ethnic Malays.
Obesity and Knee Pain Risk
Obesity is another comorbidity that is closely associated with an increased risk of knee pain. Excess body weight places additional stress on the knee joints, leading to accelerated wear and tear, which can result in pain and discomfort.
In the context of ethnicity and knee pain, it is crucial to note that the prevalence of knee pain remained significantly higher among ethnic Malays even after adjusting for confounders, including obesity. This suggests that factors other than obesity contribute to the ethnic disparities in knee pain prevalence.
Managing comorbidities, including NCDs and obesity, is crucial in addressing knee pain among different ethnic groups. Effective management strategies may involve lifestyle modifications, such as maintaining a healthy weight through diet and exercise, and appropriate medical interventions to control NCDs.
Understanding the impact of comorbidities and their association with knee pain is essential for healthcare professionals in formulating targeted interventions and treatment plans. By addressing these underlying factors, it is possible to improve the management and quality of life for individuals experiencing knee pain, regardless of their ethnicity.
Healthcare Disparities
When it comes to the management of knee pain, healthcare disparities based on race and ethnicity have been observed. These disparities can impact the quality of pain management and the preferences for treatment options.
Racial Disparities in Pain Management
Minority patients often face racial disparities in pain management. Studies have shown that minority patients are rated as having less severe pain and are less likely to receive comprehensive diagnostic and treatment approaches for pain compared to white individuals. Additionally, minority patients are less likely to receive analgesics and opioids as part of their pain management regimen. They may also experience longer wait times in the emergency department and are less likely to be admitted compared to white patients.
These disparities in pain management can lead to undertreatment of pain and inadequate relief for minority patients. It is important for healthcare providers to be aware of these disparities and work towards equitable pain management for all patients, regardless of their race or ethnicity.
Patient Preferences for Pain Treatment
Patient preferences for pain treatment can also vary among different racial and ethnic groups. For example, studies have shown that black individuals are more likely to choose or desire prescription treatment for low back pain compared to white and non-white Hispanic individuals. On the other hand, Hispanic-Americans may express hesitance to take pain medications and prefer pain self-management and other noninvasive medical treatments. This can be influenced by cultural factors, such as a strong sense of responsibility to provide for their family, which may impact their decisions about seeking pain care [4].
Understanding the preferences and cultural factors that influence pain treatment decisions can help healthcare providers tailor their approach to meet the needs of patients from different racial and ethnic backgrounds. Open communication and shared decision-making between healthcare providers and patients are essential to ensure that treatment options align with the preferences and values of the individual.
By acknowledging and addressing the healthcare disparities related to pain management, healthcare providers can strive towards providing equitable care for all patients, regardless of their race or ethnicity. It is crucial to promote culturally sensitive approaches to pain management and ensure that patients receive appropriate and effective treatment for their knee pain.
