摘要

Purpose

Gastrointestinal side effects during chemotherapy may interfere with daily consumption of a healthy diet. From the perspective of health behavior change, elderly breast cancer patients need to engage in dietary self-management behaviors to change the unhealthy diet caused by chemotherapy, ultimately improving their nutritional status and their quality of life. These behaviors can manifest as adverse reaction coping, dietary information acquisition, nutritional supplements and dietary replacement, and dietary habit regulation.

Methods

A multicenter cross-sectional study was conducted by convenience sampling from three tertiary A-level hospitals in Shaanxi and Henan Provinces. The variables included dietary self-management behavior, treatment self-regulation, outcome expectation, self-care self-efficacy, and perceived social support. Multiple stepwise regression analysis was used.

Results

A total of 868 questionnaires were ultimately analyzed. The total score for dietary self-management behavior was 68.40 ± 11.12. Living in urban areas, cancer stage II, introjected regulation, amotivation, immediate consequence consideration, future consequence consideration, positive attitude, decision making and family support were the main factors. These 10 factors explained 48.2% of the variance.

Conclusions

The performance of dietary self-management behavior needs improvement. Nursing staff should practice precise interventions related to dietary support with respect to treatment self-regulation, outcome expectation, self-care self-efficacy and social support. Moreover, women living in rural areas with low educational levels or high cancer stages constitute the targeted intervention population for the interventions.
