Was COVID-19 pandemic anxiety reflected on nutritional habits in adults?

Purpose This study aims to evaluate the reflection of COVID-19 pandemic anxiety experienced in adults on nutritional habits during the COVID-19 pandemic in Turkey. Design/methodology/approach The study was conducted with 600 adults aged between 19 and 64 years. The general characteristics of the individuals, nutritional habits, use of dietary supplements and COVID-19 pandemic anxiety before and during the pandemic period were questioned via a Web-based questionnaire. COVID-19-related anxiety was assessed using The COVID-19 Phobia Scale (C19P-S) and The State-Trait Anxiety Inventory (STAI). Data analysis was performed using the Statistical Package for Social Sciences, version 24.0. Findings In this study, 49.8% of the participants stated that their appetite and food consumption amount increased during the pandemic period. The rate of use of dietary supplements among individuals was found to be 40%. It was observed that the mean body weight and body mass index increased significantly in both genders during the COVID-19 pandemic. It has been determined that anxiety about COVID-19 is higher in individuals and women who start using nutritional support during the pandemic period. The total C19P-S and STAI scores of those who started using a dietary supplement during the pandemic were significantly higher than those who did not use a dietary supplement. Similarly, those whose eating habits changed positively and those who bought more packaged products had higher C19P-S scale mean scores (p < 0.05). Originality/value During the COVID-19 period, it is important to reduce the anxiety levels of individuals, provide psychological support, raise awareness of adequate and balanced nutrition and the correct use of dietary supplements to adapt to the new lifestyle.
