Correlates of Dietary Changes During COVID-19 in Immunosuppressed Individuals and Their Relatives: Alignment with Nutritional Recommendations

<b>Background/Objectives:</b> The sanitary measures implemented during the COVID-19 pandemic, although essential for limiting the virus propagation, hindered healthy behaviours and negatively affected mental health and quality of life. In immunosuppressed individuals at higher risk of COVID-19 complications, these measures may have influenced adherence to Canada's Food Guide 2019 (CFG-2019). This study aims to describe whether changes in eating behaviours and food consumption during the COVID-19 pandemic were aligned with CFG-2019 and identify correlates of changes in immunosuppressed individuals and their relatives. <b>Methods:</b> A total of 210 participants completed an online questionnaire between May and September 2021. Changes in eating behaviours and food consumption were categorized as no change, change aligned with CFG-2019, or change not aligned. Multinomial logistic regressions examined the association between sociodemographic, lifestyle, clinical, and psychosocial characteristics and changes in eating behaviours and food consumption. <b>Results:</b> Participants reporting no change in eating behaviours, change aligned, and change not aligned with CFG-2019 were nearly equivalent (29.4%, 33.8%, and 36.8%, respectively). For food consumption, the proportions were 17.0%, 41.2%, and 41.8%, respectively. Reduced physical activity and elevated anxiety and depressive symptoms were associated with a change in eating behaviours not aligned with CFG-2019. Perceived weight gain and decreased body image satisfaction were associated with a non-aligned change in food consumption. <b>Conclusions:</b> Dietary changes, aligned or not with CFG-2019, were observed among immunosuppressed individuals and their relatives during the COVID-19 pandemic. Identifying factors associated with these changes can inform future studies to support healthy eating among vulnerable individuals amidst stressful events such as the COVID-19 pandemic.
