It has been a well-known fact for a long time that a person with BMI of over 30 (that’s the threashold for being obese) has an increased chance of developing osteoarthritis in knees by 4 to 5 times. For example, it has been estimated t
hat the force of 3 to 6 times a person’s body weight is exerted across the knee while walking. In other words, being 10 pounds overweight increases the force on the knee by 30 to 60 pounds with each step taken while walking.
Osteoarthritis is the most common type of arthritis and is characterized by breakdown of cartilidge in joints. Osteoarhtiris does not affect only elderly people and it has been noted that youger generation with weight loss problems have shown links to increased cartiladge defects which can lead to knee osteoarthritis.
One of the studies carried out recently showed different resutls though. Scientists studied 2 groups or people – a group of over-weight people and people with high muscle weight. Surprisingly, second group did not show cartiladge damage seen in the first group. This lead scientist to beileve that the bodies of people with higher body fat produce higher levels of certain hormones what promote inflammation and responsible for some of the cartoildage damage.
We are sure every parent cares for their children and if there aren’t enough reasons to keep kids healthy then the results of this study should make every parent concerned. We should take it as another reason prevent or reverse excess weight in young adults and children. For people who are already overweight, there is evidence that losing even 11 to 15 pounds could decrease the development of knee osteoarthritis. We do suggest trying to keep your optimal weight though by either doing arthritis friendly exercises or adding anti-inflammatory food to your daily diet.
