Background: Health literacy and health-information seeking behaviour (HISB) play vital roles in health outcome improvements. This study examines the extent of income-related inequality in health literacy and health-information seeking as well as the contributions of the main socioeconomic determinants in China.

Methods: We analysed representative data of participants aged over 18 years as well as older adults from the Guangzhou Community Health Survey. A concentration index (CI) was used to quantify the degree of income-related inequity in health literacy and health-information seeking. Probit regression models were employed to decompose the CI into the contributions to each factor.

Results: Results showed a significant pro-rich distribution of adequate health literacy (CI: 0.0602, P < 0.001; horizontal index [HI]: 0.0562, P < 0.001) and HISB from healthcare professionals (CI: 0.105, P < 0.001; HI: 0.0965, P < 0.001). The pro-rich distribution of health literacy was mainly attributable to education background (contribution: 54.76%), whereas income inequalities contributed most to the pro-rich distribution of health-information seeking among an urban population (contribution: 62.53%).

Conclusion: Public interventions in China to reduce inequality in health literacy and HISBs among the urban population, coupled with easily accessible information sources on health, warrant further attention from policymakers.

While these platforms can offer evidence-based nutrition education and meal planning guidance, a significant portion of content promotes unrealistic beauty standards and unhealthy weight-loss practices, potentially contributing to disordered eating behaviors. The increasing prevalence of disordered eating, characterized by abnormal eating behaviors and attitudes, has become a global public health concern.

With advances in cancer treatment, long-term survival rates have improved in recent decades, resulting in extended life expectancies for many patients. This progress brings substantial challenges, however, particularly in terms of the costs associated with cancer care. The financial burden, often considerable, poses difficulties for older adults with cancer and their caregivers.
