Regular Kneeling Can Increase Arthritis Risk

I thought people just kneel when praying (at least Catholics do!).

However, men who spend significant amounts of time kneeling on the job are at great risk of developing osteoarthritis of the knee.

Such were the findings recently published in the American Journal of Industrial Medicine:

While several studies have suggested that people working in jobs that require spending time on one’s knees, such as floor laying, are prone to knee osteoarthritis, few have been able to quantify the amount of time spent kneeling that actually increases risk, Dr Alfred Franzblau of The University of Michigan School of Public Health in Ann Arbor and colleagues note.

Franzblau and his team evaluated 1,970 people participating in the Third National Health and Nutrition Examination Survey for whom knee X-rays were available, limiting their analysis to people who had been on their longest-held job for at least five years.

The researchers had five ergonomics experts rate occupations based on how much time a worker would spend each day sitting, standing, walking or running, carrying or lifting loads greater than 22 pounds, kneeling, or working in a cramped space.

This information “allows us to better identify the magnitude of the exposure that contributes to risk,” Franzblau told Reuters Health in an interview.

Apparently, such were the case only on men because only a small percent of women have jobs that require kneeling.

Based on these findings, the researchers estimate that 21 per cent of symptomatic knee osteoarthritis cases in men are due to working in jobs that require kneeling for more than 14 per cent of the workday. Thirty-one per cent of men in the study had jobs that met this description, including nursery or farm work or construction trades.

While just five per cent of women in the study had jobs that required kneeling, 35 per cent had jobs that required them to stand for more than 30 per cent of their work day, in activities such as operating machines or working in sales, the researchers note. This means about 19 per cent of cases of symptomatic knee osteoarthritis in women are due to working in such jobs.

The findings call for modifications in doing such jobs that require kneeling.

However, I just wonder if industrial big wigs will take the extra mile just so their employees reduce their osteoarthritis risk?
