Purpose: To describe how body mass index (BMI) influences the prevalence of chronic low back pain in the general Spanish population and assess this influence given other factors as sex, age, physical occupational demands, and recreational physical activity. Methods: An analytical cross-sectional design was performed based on secondary data from the European Health Survey in Spain (2020). Data on age, gender, physical occupational demands, physical activity, BMI, and presence of chronic low back pain were extracted. Results: A total of 19,716 (52.2% women) subjects with a median age of 53 years old were analyzed. Of these, 18.3% had chronic low back pain, 39% were overweight, and 16.1% were obese. The adjusted generalized linear model showed that being obese increased the odds of chronic low back pain by 1.719 times (p < 0.001). Being a woman increased the odds by 1.683 times (p < 0.001). Performing occupational tasks requiring high physical demands increased the odds by 1.403 times (p < 0.001). Performing physical activity in leisure time several times a week decreased the odds by 0.598 times (p < 0.001). For every additional year of age, the odds of chronic low back pain increased by 3.3% (p < 0.001). Conclusions: Obesity is related with the presence of chronic low back pain in the general Spanish population. This association persists, being the more relevant factor, after adjusting the association of BMI and chronic low back pain with other factors such as sex, age, physical occupational demands, and recreational physical activity. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 3.9 2023 PHARMACOLOGY & PHARMACY 85 / 354 = 0.24 2023 Q1 T1 BIOCHEMISTRY & MOLECULAR BIOLOGY 106 / 313 = 0.339 2023 Q2 T2 MEDICINE, RESEARCH & EXPERIMENTAL 65 / 189 = 0.344 2023 Q2 T2 0.962 2023 Medicine (miscellaneous) 2023 Q1 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2023 Q1 5.2 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hidalgo García, César Universidad de Zaragoza (orcid)0000-0001-7667-2178 Monti Ballano, Sofía Universidad de Zaragoza Márquez Gonzalvo, Sergio Universidad de Zaragoza Ferrández Laliena, Loreto Universidad de Zaragoza (orcid)0000-0002-6604-2751 Müller-Thyssen Uriarte, Julián Universidad de Zaragoza (orcid)0000-0002-9105-827X Lucha López, Ana Carmen Universidad de Zaragoza (orcid)0000-0002-8399-130X 1006 255 Universidad de Zaragoza Dpto.
