Risk Factors for Finger Degenerative Joint Disease

Demographic and Constitutional Factors

The American College of Rheumatology suggests that female sex increases risk with a relative risk of 1.23 (95% CI 1.11-1.34) for prevalence, though women have lower incidence before age 40 but dramatically higher incidence after this age compared to men 1, 2
Age over 40 years is one of the major risk factors with a likelihood ratio of 3.73 (95% CI 2.69-5.18), as it is rare for hand OA to develop before age 40 but incidence increases dramatically after this threshold 1, 3
Menopausal status appears to influence development, suggested by the gender difference dependent on age, though hormone replacement therapy studies have not shown reduced risk of hand OA 1, 3
Family history is an established risk factor for hand osteoarthritis 1, 2, 4
Obesity increases the risk of developing hand OA 1, 2, 4

Higher bone density is associated with increased risk of hand osteoarthritis 1, 2, 4
Greater forearm muscle strength has been identified as a risk factor 1, 2, 4
Joint laxity contributes to hand OA development 1, 2, 4
Prior hand injury significantly increases risk of developing hand osteoarthritis 1, 2, 4

Repetitive occupational hand tasks such as cotton picking increase risk in a dose-dependent manner, mainly targeting distal interphalangeal (DIP) and metacarpophalangeal (MCP) joints, with differential joint distribution depending on the specific repetitive tasks involved 1, 3
Highly repetitive hand tasks show moderate evidence for no increased risk of wrist/hand/finger OA when examined across men and women combined, though specific task patterns matter 5, 6, 7
Occupational activities requiring repetitive finger movements can contribute to hand OA development, particularly when involving specific joint loading patterns 1, 3
