Produce Safety Behaviors, Motivators, Barriers, and Beliefs in Pediatric Cancer Patient Caretakers

Abstract

Cancer patients, who face increased foodborne illness susceptibility and severity, are often placed on neutropenic diets (NDs), which eliminate the consumption of fresh produce, among other foods perceived as high-risk. Such diets are clinically disputed because they have never been proven effective in reducing foodborne illness, leading to unstandardized dietary guideline content, format, and delivery methods. To inform a strategic communication approach, this study explored the produce safety handling behavior, barriers, motivators, and beliefs of pediatric cancer patient caretakers using a mixed methods convergent parallel design. A quantitative survey revealed high frequencies (>60%) for generally recommended produce safety behaviors, such as rinsing produce and washing cutting boards, and more mixed responses for restrictive produce safety behaviors, such as peeling produce and avoiding precut, self-serve, and school cafeteria produce. Total produce safety frequency scores were not significantly affected by demographic factors or Child Vulnerability Scale (CVS) scores. Qualitative interviews established a wide domain of caretaker produce safety experiences and beliefs, finding that eight of seventeen interview participants from different hospitals received produce restrictions typical of the ND. Ultimately, five caretaker archetypes were identified, with common motivators and barriers linked to materials received, child’s health and perceived susceptibility, and self-efficacy beliefs. Finally, response-driven communication strategy improvements were recommended. Although sample sizes in this work were small, and further validation is advised, this work highlights the inconsistent use of the restrictive ND, advances understanding of the drivers of produce safety behaviors in cancer patient caretakers, and supports future endeavors to streamline communication strategy interventions.
