It's difficult to know who is actually at risk for arthritis, it's a very common problem that affects many people and specifically with hip arthritis there's not a direct correlation that patients that are overweight or obese are at an increased risk compared to someone of normal weight. Oftentimes arthritis runs in families, such that people that have relatives that have had arthritis are oftentimes at risk. Additionally things like trauma or previous hip injuries such as labral tears or other injuries to your hip in your adolescence or teenage years can put you at risk for arthritis later in life.
