Model 1 includes tender point count, adjusted for age, gender, and race. Model 2 includes pain categories, adjusted for age, gender, race. Model 3 included both tender point count and pain categories, adjusted for age, gender, and race. Model 4 includes all variables from model 3 and education, Body Mass Index (BMI), self reported chronic conditions: heart disease, diabetes, spinal stenosis/disc disease, gout, asthma, and stroke; daily use of analgesic medication, number of medications, depression, and blocks walked per week.
