Wuchuan Osteoarthritis Study is a population-based longitudinal study of natural history of knee osteoarthritis and its risk factors. At baseline and follow-up visits, IPA-Q questionnaire and a radiographs at tibiofemoral (TF) joints will be taken in order to assess the relationship between physical activity and radiographic osteoarthritis worsening.
1025 residents aged ≥ 50 years will be recruited using door-to-door enumeration in randomly selected rural communities in Wuchuan, China, and will be followed in 3 years. At baseline and follow-up visits, subjects will complete a home interview (including, but not limited to, socio-demographic factors, physical activity level using IPA-Q questionnaire,WOMAC questionnaire) and have a weight-bearing posteroanterior semiflexed view of radiographs at tibiofemoral (TF) joints. Radiographic osteoarthritis (ROA) worsening for a knee is defined if its Kellgren and Lawrence (K/L) grade increases by at least 1 grade except for the change from 0 to 1 during follow-up. The relationship between level of physical activity and ROA worsening will be assessed.

Exclusion Criteria:
All residents that meet the criteria can be enrolled in this group, receiving a home interview (including IPA-Q to assess the level of physical activity) and a weight-bearing posteroanterior semiflexed view of radiographs at tibiofemoral (TF) joints at baseline and 3 years later.
Other: level of physical activity
According to the result of IPA-Q questionnaire, participants are divided in three groups: low level, moderate level, high level of physical activity.
worsening of radiographic osteoarthritis
The tibiofemoral radiograph of both knee joint will be taken at baseline and in 3 years. Knee radiographs will be read by one investigator according to Kellgren and Lawrence (K/L) criteria. A knee will be defined as ROA worsening if its K/L grade increased by at least 1 grade except for the change from 0 to 1 during follow-up.
