Physical activity and sedentary behavior were assessed using the IPAQ-short form. CLBP was defined as low back pain occurring almost daily for \u22653\u202fmonths. Sociodemographic, lifestyle, and health-related factors were collected as covariates. Associations were examined using chi-square tests and multivariable logistic regression models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The prevalence of CLBP was 16.1%. Individuals who met physical activity guidelines had a significantly lower risk of CLBP (adjusted OR\u202f=\u202f0.218, 95% CI: 0.116\u20130.410). Sedentary behavior was independently associated with a higher risk of CLBP (adjusted OR\u202f=\u202f2.720, 95% CI: 1.562\u20134.738). Stratified analyses showed consistent associations across subgroups defined by sex, residence, marital status, lifestyle factors, and chronic diseases, with no significant interaction effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Insufficient physical activity and sedentary behavior are major modifiable risk factors for CLBP in middle-aged and older adults.
