Risk factors linked to knee osteoarthritis in people from Taiyuan, China

Circadian Biology Weekly Brief ↗PubMed ↗

Updated Apr 3, 2026

Abstract

The prevalence rates of knee pain and KOA were 13.6% and 10.9%, respectively.

Knee osteoarthritis (KOA) was found to be significantly more prevalent in women compared to men (18.3% versus 8.7%).
The prevalence of KOA increased with age, particularly in women after 40 years and in men after 45 years.
Body mass index (BMI) was significantly higher in individuals with KOA compared to those without.
Age, sex, and BMI are significantly associated with the presence of KOA.
No significant correlation was found between KOA and factors such as climbing stairs, waist circumference, or smoking history.
