There are several studies associating low back pain with depression, because of the general passive attitude of depressed people and the general psychological factors of depressed people which are involved in chronic low back pain and low back pain. Although studies have shown an association between low back pain and depression, little is known about the role of socio-demographic factors that may also play a role in this association. In particular, in Crete, with its particular socio-economic and environmental (climatic) characteristics, there is no relevant research on the relationship between back pain and depression. The aim of this study is to identify the association between low back pain and depression in patients of a large Greek region, the Region of Crete, in order to contribute to the entire Greek literature, but also to the overall effort to find solutions for patients back pain, who also have problems with depression. In order to achieve the purpose of this study, a quantitative survey was conducted. According to the results of the present study, it is concluded that the pain is more intense and affects more these patients suffering from low back pain, in contrast to the patients of the control group. In addition, severe and chronic low back pain affects both the depression and anxiety of these patients, who have more sleep problems than the control group, where there is no correlation. http://pubs.sciepub.com/ajcmr/9/2/4/ajcmr-9-2-4.pdf lowback pain depression anxiety sleep problems chronic pain
