Objective: To determine the direct relationship between kinesiophobia and the body mass index (BMI) with an impact on the quality of life and as negative predictors in the degree of disability in these patients.

Design: Cross-sectional study. Setting : Department of Physical Medicine and Rehabilitation of Hospital Civil de Guadalajara Fray Antonio Alcalde, Guadalajara, Mexico. Participants : Fifty-nine patients, aged 18-65 years, both genders, without limitation for standing, with independent gait and chronic mechanical low back pain, pregnant women were excluded, use of some auxiliary device for gait, history of some surgical management in the spine, cancer patients.

Interventions: Not applicable.

Main Outcome Measures: Fear of movement was assessed using Tampa scale for kinesiophobia (TSK-11). A higher TSK-11 score is indicative of a higher level of fear. BMI was also calculated with Du Bois method, we analyzed the interrelationship between scores using Spearman rank correlation coefficient.

Results: Mean age was 47.66 years, mean BMI was 29.55 and mean TSK-11 was 32.51 in the total sample. Statistical analysis using the Spearman rank correlation coefficient found rho (p) to be 0.424, suggesting a positive relationship between BMI and TSK-11, determining that increasing the BMI of patients increases the kinesiophobia rating. Conclusions: It was concluded that the increase in BMI is directly related to the result of the TSK-11 scale, which is reflected in an increase in disability and a decrease in the quality of life in patients with chronic mechanopostural low back pain. Multidisciplinary treatment is necessary to reduce body weight and reduce fear of physical activity so that we can improve the quality of life in our patients.

Level of Evidence: Level III
