Background:
Chronic low back pain (CLBP) is frequently seen in the orthopedic outpatient consultation. The aim of this paper is to identify risk factors associated with CLBP in patients cared for during the year 2012, at a General Hospital belonging to Instituto Mexicano del Seguro Social, in Yucatán, Mexico.
Methods:
Data of 95 patients with CLBP (cases) was compared with data of 190 patients without CLBP (controls) using a binary logistic model (BLM), from which odd ratios (OR) and 95 % confidence intervals (95 % CI) were obtained.
Results:
School level, body mass index (BMI) as a continuous variable, story of heavy weight lifting, some types of comorbidities and dyslipidemia, were identified as statistically significant in the bivariate analysis (p ≤ 0.05 each). In a second step, secondary school level (OR 0.25, 95 % CI: 0.08-0.81), dyslipidemia (OR 0.26, 95 % CI: 0.12-0.56), heavy weights lifting (OR 0.22, 95 % CI: 0.12-0.42), and BMI (OR 1.22, 95 % CI: 1.12-1.32) were all identified by the BLM as statistically significant.
Conclusions:
In this sample, secondary school level, dislipidemia and heavy weights lifting reduced the risk of CLBP, while the BMI increased the risk.
