Key result
Demographic factors, hypertension, hemoglobin levels, breakfast frequency, and intake of sodium, vitamin D, and vitamin C were identified as significant factors influencing BMI in cancer survivors.
Why the study?
Obesity in cancer survivors increases the risk of recurrence and affects mortality, prompting investigation into the relationship between health-related characteristics and BMI.
What demographic, health, and nutrition-related factors influence body mass index in cancer survivors?
Cross-Sectional (n=4,553,669)
What demographic, health, and nutrition-related factors influence body mass index in cancer survivors?
Various demographic, health, and nutritional factors significantly influence BMI in cancer survivors, highlighting the need for tailored interventions to manage obesity and improve survival outcomes.

Several factors associate with BMI in cancer survivors; hypothesis-generating for targeted assessments, prospective trials needed before practice change.
BACKGROUND: Lifestyle habits and genetic factors of cancer survivors can lead to recurrence or development of new cancers. Obesity in cancer survivors increases the risk of cancer recurrence and affects mortality. This study aimed to analyze the relationship between health-related characteristics and related factors in cancer survivors by classifying obesity according to body mass index. METHODS: This study is a secondary data analysis research study using 5-year data, including 3-year (2016-2018) and 2-year data (2019-2020) from the 7th and 8th Korea National Health and Nutrition Examination Survey, respectively. This study targeted 4,553,669 cancer survivors who had completed past or early cancer management, did not have active cancer, or were receiving treatment for advanced cancer but were not in the terminal stage. Data were analyzed with complex sample descriptive statistics, cross-tabulation analysis and chi-square test and t-test. Lastly, complex sample multivariable linear regression analysis using IBM SPSS software. RESULTS: Demographic factors such as gender (t = -4.07, p <.001), marital status (t = 4.20, p <.001), and economic activity (t = -3.27, p =.002); health factors such as hypertension (t = 9.07, p <.001) and hemoglobin level (t = 5.29, p <.001); and nutrition-related characteristics such as frequency of breakfast (t = -6.49, p <.001), sodium intake (t = 2.41, p =.17), vitamin D intake (t = 3.02, p =.003), and vitamin C intake (t = -3.43, p =.001) were significant factors influencing cancer survivors' BMI. CONCLUSIONS: The results of this study are significant as they confirm the relationship between health-related characteristics and BMI in cancer survivors. The study comprehensively identified and presented various factors related to BMI in the lives of cancer survivors. To control BMI in cancer survivors, it is necessary to assess risk factors and change health behaviors and eating habits. Based on these results, developing and applying health intervention programs to prevent BMI increases and managing obesity in cancer survivors is essential. Promoting health strategies and studying the relationship with BMI in the future will contribute to increasing the healthy survival rate of cancer survivors.

Ku et al. (2025) conducted a cross-sectional in Cancer survivors (n=4,553,669). Health and nutritional characteristics was evaluated on Factors influencing body mass index (BMI). Demographic factors, hypertension, hemoglobin levels, breakfast frequency, and intake of sodium, vitamin D, and vitamin C were identified as significant factors influencing BMI in cancer survivors.
