A new study that surveyed 1 million Americans shows a clear association between obesity and pain.
The study, done by Stony Brook University Medical Center in New York and published in January in an online edition of Obesity, found not only was there a clear link between pain and obesity, but also that people who were the heaviest suffered higher rates of pain.
Researchers surveyed 1,010,762 people via telephone over a two-year period, from 2008 to 2010. Height, weight and body mass index were calculated, along with detailed questions about pain.
"Our findings confirm and extend earlier studies about the link between obesity and pain," said Dr. Arthur A. Stone, vice chairman of the department of psychiatry and behavioral medicine at the university. "These findings hold true after we accounted for several common pain conditions and across gender and age."
Sixty-three percent of the people responding to the survey were classified as overweight (38 percent) or obese (25 percent). Obese respondents were further classified into one of three obesity levels as defined by the World Health Organization.
