Outline
To analyze the prevalence and influencing factors of physical pain among Chinese elderly, providing evidence for pain identification and intervention.
Data from 6 191 elderly participants in the China Health and Retirement Longitudinal Study (CHARLS) were analyzed using ordinal logistic regression and random forest algorithms to assess the impact and importance of various factors on pain severity.
59.13% of elderly individuals reported pain, with over 30% experiencing moderate or severe pain. The most common pain sites were the lower back, knees, and legs. Male gender (OR=0.695, 95% CI=0.614-0.787), higher education (OR=0.870, 95% CI=0.766-0.988), and retirement (OR=0.802, 95% CI=0.699-0.921) are protective factors. BADL disability (OR=2.071, 95% CI=1.832-2.340), IADL disability (OR=1.990, 95% CI=1.756-2.235), depressive symptoms (OR=1.548, 95% CI=1.378-1.739), poor sleep quality (OR=1.530, 95% CI=1.334-1.756), arthritis or rheumatism (OR=2.486, 95% CI=2.244-2.753), Parkinson’s disease (OR=1.679, 95% CI=1.160-2.428), digestive diseases (OR=1.642, 95% CI=1.478-1.824), cancer (OR=1.554, 95% CI=1.143-2.112), kidney disease (OR=1.543, 95% CI=1.331-1.788), heart disease (OR=1.457, 95% CI=1.299-1.636), and chronic lung diseases (OR=1.190, 95% CI=1.034-1.371) are risk factors. Random forest analysis showed that arthritis, BADL, IADL, depression, and sleep quality were key factors influencing pain severity.
The physical pain burden among elderly Chinese is significant and influenced by multiple factors. Pain management should focus on early identification and individualized interventions for high-risk groups to improve quality of life.
