The total cost of low back pain in 1986 was around $11.1 billion dollars 2 . Previous researchers have uncovered disparities in the presentation and treatment of low back pain, finding that African American individuals report more severe pain than Caucasian individuals 3 . Other research has examined racial disparities in pain severity, and found that different racial groups experience pain in a similar fashion 4 . Few studies have addressed racial or socioeconomic disparities in physical functioning of patients with low back pain. In this study, we will examine ethnic and socioeconomic differences in pain severity, physical function, and treatments for pain. Subjects. Student research assistants enrolled 367 adult patients from 9 outpatient clinics across Texas. Patients were eligible if they had low back pain for 3 months or longer, and were excluded if they were pregnant or had a diagnosis of cancer. Procedure and Measurement . Students gathered data from patient surveys and medical records. A 6-page patient survey addressed demographic characteristics, pain duration, frequency and severity, physical functioning and general health, anxiety, depression, substance abuse, and risk for opioid misuse. Patients reported pain severity using a 10-point scale. Investigators assessed physical function, role function, and general health using composite scores based on items from the MOS Short Form- 36. Ten items addressed physical function (ability to perform physical activities); four items addressed role function (ability to perform daily work); and four items addressed general health (feelings of wellness versus illness). In all 3 scales, a higher score indicated higher function or better health. From participants’ medical records, students gathered information about causes of low back pain, treatments for pain (including medications, procedures, and surgeries), comorbidities, and Body Mass Index (BMI). This study of patients with chronic low back pain demonstrated a clear difference between African Americans and other racial/ethnic groups. African Americans had significantly worse pain and role function. Likewise, insurance status and education, indicators of socioeconomic status, were associated with pain, function, and use of opioids, This finding is in contrast to other research studies which found that socioeconomic status and ethnicity did not significantly affect the rate of prescription of various treatments 5 . More research needs to be done in order to determine the specific reasons why African Americans have worse pain than other groups. In addition, future studies should investigate other factors related to opioid use, such as occupation, hours worked, and other social, economic and cultural factors. 1. "ACA - Back Pain."

ResultsAccording to the American Chiropractic Association, over 30 million Americans have had low back pain at some point in their lives1. The total cost of low back pain in 1986 was around $11.1 billion dollars2. Previous researchers have uncovered disparities in the presentation and treatment of low back pain, finding that African American individuals report more severe pain than Caucasian individuals3. Other research has examined racial disparities in pain severity, and found that different racial groups experience pain in a similar fashion 4. Few studies have addressed racial or socioeconomic disparities in physical functioning of patients with low back pain. In this study, we will examine ethnic and socioeconomic differences in pain severity, physical function, and treatments for pain.

Subjects.  Student research assistants enrolled 367 adult patients from 9 outpatient clinics across Texas.  Patients were eligible if they had low back pain for 3 months or longer, and were excluded if they were pregnant or had a diagnosis of cancer.

Procedure and Measurement.  Students gathered data from patient surveys and medical records. A 6-page patient survey addressed demographic characteristics, pain duration, frequency and severity, physical functioning and general health, anxiety, depression, substance abuse, and risk for opioid misuse.  Patients reported pain severity using  a 10-point scale.  Investigators assessed physical function, role function, and general health using composite scores based on  items from the MOS Short Form-36. Ten items addressed physical function (ability to perform physical activities);  four items addressed role function (ability to perform daily work); and four items addressed general health (feelings of wellness versus illness). In all 3 scales, a higher score indicated higher function or better health. From participants’ medical records, students gathered information about causes of low back pain, treatments for pain (including medications, procedures, and surgeries), comorbidities, and Body Mass Index (BMI). 

This study of patients with chronic low back pain demonstrated a clear difference between African Americans and other racial/ethnic groups. African Americans had significantly worse pain and role function. Likewise, insurance status and education, indicators of socioeconomic status, were associated with pain, function, and use of opioids, This finding is in contrast to other research studies which found that socioeconomic status and ethnicity did not significantly affect the rate of prescription of various treatments 5. More research needs to be done in order to determine the specific reasons why African Americans have worse pain than other groups. In addition, future studies should investigate other factors related to opioid use, such as occupation, hours worked, and other social, economic and cultural factors.
