Weight, height, waist circumference: association with knee osteoarthritis findings from the osteoarthritis initiative.

Higher weight in female participants was a stronger predictor of increases in knee osteoarthritis discomforts when compared to waist circumference, while weight and waist circumference were almost equivalent in predicting increases in knee osteoarthritis for male participants. Height did not predict increases in knee osteoarthritis with the exception of female symptoms and quality of life. Quality of life for both sexes was the most unfavorable with female participants reporting a more unfavorable quality of life than male participants.
