Influence of age on financial toxicity in cancer patients.

Objective: The aim of this study was to assess the level of financial toxicity (FT) experienced by the following three age groups of cancer patients in China: young working-aged patients (age < 40 years), middle-aged patients (40-64 years), and older patients (≥ 65 years). Methods: The data used for this study were collected via a cross-sectional survey conducted in China. FT was assessed using the Comprehensive Score for Financial Toxicity (COST). ANOVA was used to examine the differences in FT status between age groups. Multivariate linear regression models were employed to assess the association between age and FT, adjusted by socioeconomic and other clinical characteristics. Results: A total of 556 cancer patients completed the survey. Approximately 54.3% of the participants were male and 45.7% were female. The majority (61.5%) were aged 40-64 years, while 27.7% were aged 65 or older. The mean FT scores for young patients (< 40 years), middle-aged patients (40-64 years), and older patients (≥ 65 years) were 16.7, 12.8, and 12.4, respectively. The results of the regression analysis revealed that, without adjusting for background characteristics, young patients had significantly higher mean COST scores. This suggests they experienced lower levels of FT compared to patients in other age groups. Stratified analysis revealed that, for older patients, only educational level and type of insurance scheme were significant factors in predicting the COST score. Conclusions: This study provides empirical evidence for developing targeted interventions and policies to reduce the FT for patients in different age groups. Given that FT is complicated, a longitudinal study should be conducted to explore the long-term impact of FT on cancer patients' quality of life and well-being.
