ABSTRACT BACKGROUND AND OBJECTIVES: Low back pain is the main cause of global disability and is prevalent in women, tending to increase after menopause. The present study aimed to analyze the correlation between body mass index, muscle strength, kinesiophobia, estradiol, functional disability, and low back pain perception in postmenopausal women with chronic low back pain. METHODS: Twenty-two postmenopausal women with chronic low back pain were evaluated. Abdominal and lower back strength were assessed using isometric tests. Basal serum estradiol levels were analyzed using the chemiluminescence method. Kinesiophobia, low back pain perception, and low back functional disability were determined using the Tampa Scale for Kinesiophobia, the visual analog scale, and the Roland Morris Questionnaire, respectively. RESULTS: The Spearman correlation test showed correlations between the levels of kinesiophobia and the value of body mass (rho= -0.513; p=0.015) and the levels of kinesiophobia and the values of body mass index (rho= -0.576; p=0.005). There was correlation between the levels of kinesiophobia and perception of lumbar functional disability (rho= 0.434; p=0.043). No significant correlations were found between the variables of muscle strength, estradiol, and low back pain perception. CONCLUSION: Postmenopausal women with low back pain who have higher body mass and body mass index values tend to present lower levels of kinesiophobia. There is a direct relationship between the fear of moving or maintaining a specific position and the perception of the functionality and safety of the lumbar spine.
