Correlation between pain, anthropometric measurements, stress and biochemical markers in women with low back pain.

Aim: To analyze the associations between pain duration, pain levels, anthropometric measures, perceived stress and biochemical markers in women with low back pain. Materials & methods: Forty-two participants were submitted to body mass, height, abdominal circumference, cortisol and creatine kinase (CK) collections. Pain duration, pain levels and stress were analyzed through specific questionnaires. Results: There were positive correlations between abdominal circumference and body mass, duration of pain and age, abdominal circumference, CK and age, CK and BMI, CK and abdominal circumference, and CK and duration of pain (p < 0.05). Conclusion: The higher the level of tissue damage over the years, the greater the tendency for higher levels of low back pain perception. Central fat was related to greater load on the spine.
