RESUMO
The purpose of the study was to evaluate the relationship between health behavior and pain scale in patients with low back pain. One hundred eighty patients with low back pain attending the Orthopedic Unit at Sapasithiprasong Hospital in Thailand participated in the study. The participants completed a questionnaire related to demographic data and preventive health behavior, illness health behavior and sick role health behavior. Statistical analysis was used to calculate means, standard deviations and percentages, multiple regression evaluated the relationship between demographic data and pain scale, and Pearson's correlation assessed the relationship between the three health behaviors and pain scale. Generally, the results showed most participants had a lower quality of health behavior. The most common causes of low back pain were lifting heavy loads, incorrect positioning and everyday activity (43.9, 17.8 and 10.6%, respectively). The level of participant's income was found to be statistically relevant to pain scale (p < 0.05). There was also a statistically significant association between the three health behaviors and pain scale (p = 0.0001, 0.005, 0.0001, respectively). The findings of this study illustrate the crucial role that Thai health care professionals play in changing the health behavior of patients with low back pain in order to improve the patient's quality of life.
