PurposeEven though it is known that fear and poor sleep quality trigger emotional eating, whether fear of COVID-19 and poor sleep quality have effects on emotional eating during the COVID-19 pandemic is not clear. This study was performed to evaluate the effect of fear of COVID-19, sleep quality and sociodemographic characteristics such as age, gender, BMI on emotional eating during COVID-19 pandemic in Turkey.MethodsThe research data were collected via the ‘Participant Information Form’, the ‘Fear of COVID-19 Scale’, the ‘Pittsburgh Sleep Quality Index’, and the ‘Emotional Eating Scale’.ResultsFear of COVID-19 Scale score (β: 0.090, p < 0.05) and Pittsburgh Sleep Quality Index score (β: 0.289, p < 0.001) separately affected the Emotional Eating Scale score in the rate of 0.8% and 8.3%, respectively. Fear of COVID-19 Scale score (β: 0.042, p > 0.05), Pittsburgh Sleep Quality Index score (β: 0.246, p < 0.001), age (β: -0.259, p < 0.001), gender (β: -0.169, p < 0.001) and Body Mass Index (β: 0.275, p < 0.001) were affecting Emotional Eating scale score in rate of 18.3%. Fear of COVID-19 alone has a minimal effect on emotional eating, but when combined with variables such as sleep quality, BMI, age and gender, its effect on emotional eating disappears.ConclusionsIn the light of these results, it is recommended to screen all individuals in the society during the pandemic in terms of emotional eating, especially those who are young, female, have a high BMI, low sleep quality, and high fear of COVID-19 and nutrition education should be provided to these people.Level of evidenceLevel V, cross-sectional predictive study.
