BACKGROUND: Healthy eating is vital to well-being and during the COVID-19 pandemic, it was especially important for boosting immunity and protecting against viral infections. Yet, by many accounts, keeping a nutritious diet was a casualty of the pandemic rather than a means to fight it. Young adults experienced disproportionate pandemic-related disruptions during a formative stage of development while little is still known about dietary outcomes. METHODS: We employed a cross-sectional design to examine dietary disparities targeting young adults (ages 18-28) during the COVID-19 lockdown period. Participants (N = 254) responded to a 15-20-min online survey with questions related to food composition and sources of food, perceptions of healthy eating, weight change, physical activity, and food insecurity. Comparisons were made by household income and gender. Multiple regression analyses were conducted to investigate factors that predicted perceptions of healthy eating behaviors while controlling for other sociodemographic factors. RESULTS: A clear overall trend toward unhealthy behaviors was found while positive changes were also identified. Consumption of junk food significantly increased (+ 3%), 40% gained weight, a third were less active, and 5-8% were food insecure on a regular basis. Meanwhile, eating food from restaurants declined and, for some, home-based cooking increased. Lower income participants were overly represented in unhealthy changes and higher income participants were disproportionately represented in healthy changes. Males reported more changes in dietary composition while females reported more fluctuation in weight. Reduced activity, weight gain, and food insecurity predicted unhealthy eating behaviors. Living with friend(s)/roommate(s) predicted healthier eating, but only among lower income participants. CONCLUSIONS: It is recommended that pandemic minded public health interventions account for negative dietary trends with particular attention to low-income young adults. Solutions should be geared toward reshaping fiscal, social and physical environments, rather than relying solely on behavioral interventions.
