The Relationship Between Physical Activity and Radiographic Osteoarthritis Worsening
November 25, 2017 updated by: Lin Chutong, Peking University People's Hospital
The Relationship Between Physical Activity and Radiographic Osteoarthritis Worsening: Wuchuan Osteoarthritis Study
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.

Detailed Description
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.

Wuchuan residents
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.
|
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
Time Frame: 3 years after enrollment
|
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.
