The risk factor for arthritis that has received most attention is obesity. Arthritis is one of the most frequent chronic conditions with a prevalence, which increases steeply with age. A consequence of this is that the prevalence of arthritis is expected to increase dramatically with the aging of the baby boomer population.
The self-reported findings from this large Canadian longitudinal study spanning 18 years showed that for people in the same age group, a higher proportion of them in each successive generation reported arthritis than their counterparts in earlier generations. This suggests that over time people are reporting arthritis at a younger age. In addition, as body weight increased so too did the probability of getting arthritis.
