Although survivors are at elevated risk for low BMD, prior studies have focused on specific cancer types and relied on traditional regression models, which are limited in capturing complex inter-variable relationships. This study aimed to examine the causal relationships among factors affecting BMD in cancer survivors and age-matched controls using causal Bayesian network (CBN) modeling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Data from the 2010-2011 Korea National Health and Nutrition Examination Survey (KNHANES) V were analyzed. We included 227 cancer survivors and 681 age- and sex-matched controls. Associations between BMD and variables such as age, sex, body composition, smoking, fracture history, and vitamin D were assessed using linear regression. A CBN model was then applied to evaluate probabilistic dependencies and potential causal relationships between variables and femoral neck BMD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Among all participants, age, sex, smoking, fracture history, body fat percentage, muscle mass, and cancer history were significantly associated with femoral neck BMD. In cancer survivors, age (\u03b2\u2009=\u2009\u22120.032,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.001) and sex (\u03b2\u2009=\u2009\u22120.680,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.001) showed negative associations with BMD, whereas higher muscle mass (\u03b2\u2009=\u20090.073,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.001) was a strong positive predictor.

The CBN model identified direct effects of age and muscle mass on BMD, with indirect effects from sex, smoking, and fracture history. Among women aged &gt;60\u2009years, greater muscle mass appeared particularly protective.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Causal Bayesian network modeling identified muscle mass as a key modifiable factor influencing BMD among cancer survivors. These findings highlight the importance of muscle-preserving lifestyle interventions, including resistance exercise and adequate protein intake, in survivorship care.
