The purpose of the study conducted by Grotle et al was to examine the effects of obesity on osteoarthritis (OA) in the knee(s), hand(s) and/or hip(s) (Grotle et al 2008). Similarly, the risk factors of OA that are discussed within this article are also are being looked at for the research portion of the disease seminar final presentation of our group.
One of the most important risk factors for OA is obesity. According to the article, obesity is DEFINED a body mass index (BMI) of 30 or above (Grotle et al 2008). The researchers found that in 2004, 10 years after the study initially began, the amount of respondents with a BMI of 30 or above had increased by 6.9% from 1994 (Grotle et al 2008). As a result of this, the incidence rates of OA prospering in regions like the knee, hand and hip had also risen (Grotle et al 2008). This is a perfect example of the risks that come with being overweight. However, the most impacted region by OA, in association with obesity, is the knee (Grotle et al 2008). The information provided by the article sets forth a great example of what I acquired during my research. Being overweight is not only detrimental to the body’s healthy state of mind, it also a big determinant of OA later in life. The more stress (weight) placed on knee joints, in particular, the more wear and tear will be present and therefore OA will develop.
Obesity not only places immense pressure on knee(s), it can also lead to OA in the hands (Grotle et al 2008). According to the data collected in the study, hand OA was apparent more in women than men (Grotle et al 2008). Surprisingly though, having a high BMI is strongly affiliated with OA in knees and hands but not with the hip (Grotle et al 2008), something that I had thought was an area that had to be affected significantly as a result of OA.
