Which of the following is the primary risk factor for the development of osteoarthritis?
Age over 65 years
Family history of osteoporosis
Sedentary lifestyle
Obesity
The Correct Answer is D
Obesity is a primary risk factor for the development of osteoarthritis, particularly in weight-bearing joints such as the knees and hips. Excess weight puts increased stress on the joints, leading to cartilage breakdown and the development of osteoarthritis. While age, family history, and a sedentary lifestyle can also contribute to the development of osteoarthritis, obesity is the most significant risk factor.
a. While age over 65 years is a risk factor for osteoarthritis, it is not the primary risk factor. Osteoarthritis can occur at any age, especially if other risk factors are present.
b. Family history of osteoporosis is not a primary risk factor for osteoarthritis. Osteoarthritis and osteoporosis are separate conditions with different risk factors.
c. While a sedentary lifestyle can contribute to the development of osteoarthritis, it is not the primary risk factor. Obesity is a more significant risk factor in this context.

Obesity is a modifiable risk factor for osteoarthritis. Excess body weight puts increased stress on weight-bearing joints, such as the knees and hips, leading to accelerated wear and tear of the joint cartilage.
a. Age over 60 years is a non-modifiable risk factor for osteoarthritis. While the risk of osteoarthritis increases with age, the age itself cannot be modified.
b. Female gender is a non-modifiable risk factor for osteoarthritis. Women have a higher risk of developing osteoarthritis compared to men, but gender cannot be modified.
c. Family history of osteoarthritis is a non-modifiable risk factor. Having a family history of the condition increases the risk, but it cannot be modified.
