I've heard that my chances of getting hip arthritis are less if I live in the South. Is this true?

The number of people with arthritis of the hip (called primary osteoarthritis) is not related to latitude or longitude. Ethnic background and genetics (passed down in families) seem to be much stronger factors. Compared to Blacks, Hispanics, Native Americans, and Asians, Whites (Caucasians) are much more likely to have hip osteoarthritis. Specifically, if you are white and have a mother, father, sister, or brother with primary osteoarthritis, your chances of getting hip osteoarthritis are much greater than those of other groups.
