Fear-avoidance beliefs are related to the prognosis of chronicity in low back pain in subacute stages, however in chronic pain, is no clear the influence of these factors; it has been suggested that the study population can determine the magnitude of influence on disability and pain of those suffering from back pain. Currently, information does not exist in the Mexican population.
To analyze the relationship between fear-avoidance beliefs with pain and disability in Mexicans with chronic low back pain; analyze potentials differences between subgroups according to the time of evolution.
Cross-sectional study in Mexicans with chronic LBP aged between 18 and 45. Data were collected on general socio demographic characteristics, time of evolution, body mass index, pain, disability and fear-avoidance beliefs.
33 men and 47 women, with an average age of 34.19±7.65 years. Higher scores of fear-avoidance beliefs were obtained in women (47.2±20.99 versus 38.5±9.7; p=0.05) and single participants (p=0.04). A positive correlation was found between disability (r=0.603, p<0.001) and pain (r=0.234, p=0.03) with high scores of fear-avoidance beliefs. Through generalized linear models for disability, total score of the fear avoidance beliefs questionnaire showed a standardized beta coefficient of 0.603, p<0.001 (R of 0.656); for pain showed a standardized beta coefficient of 0.29, p=0.01 (R of 0.721).
The present study suggests that there is a strong relationship between pain severity, FABQ scores, and functional disability in Mexicans with chronic LBP.
恐惧回避信念与亚急性阶段下腰痛的慢性化预后相关，然而在慢性疼痛中，这些因素的影响尚不清楚；有人提出研究人群可以决定这些因素对腰痛患者残疾和疼痛的影响程度。目前，墨西哥人群中尚无相关信息。
分析慢性下腰痛墨西哥患者恐惧回避信念与疼痛及残疾之间的关系；根据病程分析亚组间的潜在差异。
对18至45岁的慢性下腰痛墨西哥患者进行横断面研究。收集了一般社会人口学特征、病程、体重指数、疼痛、残疾和恐惧回避信念等数据。
33名男性和47名女性，平均年龄34.19±7.65岁。女性（47.2±20.99对38.5±9.7；p=0.05）和单身参与者（p=0.04）的恐惧回避信念得分更高。残疾（r=0.603，p<0.001）和疼痛（r=0.234，p=0.03）与高恐惧回避信念得分之间存在正相关。通过残疾的广义线性模型，恐惧回避信念问卷总分显示标准化β系数为0.603，p<0.001（R为0.656）；对于疼痛，标准化β系数为0.29，p=0.01（R为0.721）。
本研究表明，慢性下腰痛墨西哥患者的疼痛严重程度、FABQ得分和功能残疾之间存在密切关系。
