## TL;DR

This study explores how university students' beliefs and behaviors relate to COVID-19 prevention and their dietary habits.

## Contribution

The study applies the Health Belief Model to understand gender and age differences in prevention behaviors and diet among undergraduates.

## Key findings

- Female students reported more prevention behaviors and stronger health beliefs than males.
- Older students practiced more prevention behaviors and perceived fewer barriers than younger students.
- Participants consumed low amounts of fruits and vegetables, indicating poor dietary habits.

## Abstract

Physical and social disruptions resulted from the COVID-19 pandemic, affecting young adults in higher education. The purpose of this survey research is to unveil COVID-19 related beliefs using the Health Belief Model, and COVID-19 prevention behaviors, including self-reported fruit and vegetable consumption among university students. A cross-sectional survey was administered to 304 male and female undergraduate students from diverse ethnic backgrounds and majors at a New Jersey state university using convenience sampling. Variables measured included frequency of COVID-19 prevention behaviors (e.g.: wearing indoor mask, handwashing), and consumption of fruit and vegetables (dark green and orange vegetables) over the previous week. Health Belief Model constructs were assessed namely perceived susceptibility to COVID-19, severity, benefits, barriers, and self-efficacy. Statistical distributions were computed for the entire sample and t-tests were investigated for subgroups of age and sex. The sample mean age was 21.7 (SD = 4.7) years with 222 females (73%) and 82 males (27%), and 46% identified as White, non-Hispanics. Participants consumed a mean of 0.95 cups of fruit, 0.81 cups of green vegetables, and 0.46 cups of orange vegetables. Female students practiced more COVID-19 prevention behaviors with a mean difference of 0.26 (p<0.001), perceived greater severity from the virus (Δ = 0.37, p = 0.002) and had stronger perceptions of benefits (Δ = 0.18, p = 0.041), barriers (Δ = 0.21, p = 0.046), and self-efficacy (Δ = 0.20, p = 0.020) than their male counterparts. Older students (aged 23 and above) adopted more COVID-19 prevention behaviors (Δ = -0.35, p = 0.001) and perceived less barriers (Δ = 0.24, p = 0.047) than their younger peers. Nutrition educators and health professionals need to emphasize the importance of adopting preventive health behaviors among university students as strategies to mitigate the severity of COVID-19. Addressing barriers younger male and female students may elevate their motivation and self-efficacy to enact health behaviors.
