Multivariate logistic regression analysis revealed that living alone, low monthly household income, advanced age, frailty status, self-care ability, current work participation, rural residence, and multiple medication use were significant influencing factors for the latent classes of intrinsic capacity (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The deterioration of intrinsic capacity among rural older adult populations exhibits distinct categorical patterns.
