Article Abstract:
Physically demanding tasks both at work and home appear to increase the risk of osteoarthrosis of the hip in women. Osteoarthrosis of the hip is a degenerative joint disease characterized by pain and limited movement. Researchers questioned 503 women about their daily activities at home and work. A total of 230 women had received an artificial hip. Women who jumped or moved between different levels, climbed stairs often or performed physically demanding tasks at home had twice the risk of osteoarthrosis. Those who performed these tasks at work and home had four times the risk.

Article Abstract:
Many factors come into play in causing osteoarthritis of the knee. Predisposing factors include increasing age, congenital problems and developmental diseases, overweight, injury, and female sex. Hereditary factors probably play little if any part and estrogen use in women may be protective. In addition, heavy physical labor such as found in dockers and coal miners and work that entails squatting, kneeling, or climbing stairs also seems to predispose to osteoarthritis of the knee. Nonetheless, some persons will develop osteoarthritis of the knee with no predisposing factors.

Article Abstract:
Obesity and estrogen therapy appear to increase the risk of osteoarthritis of the knee, while smoking appears to decrease the risk. Swedish researchers compared 625 people with degenerative knee joint disease and 548 similar healthy people. Obese women were nine times as likely, and obese men 4 times as likely, to develop knee osteoarthritis than non-obese people. Smokers had a lower risk of osteoarthritis, and women taking estrogen hormone replacement after age 50 had twice the risk of knee joint disease.
