ABSTRACT
OBJECTIVE: It is known that social isolation process has an impact on individuals' eating behaviours. Continuing nutritional behaviour resulting from emotional eating, uncontrolled eating and cognitive restriction may turn into eating disorders in the future. The purpose of this study is to evaluate the possible effects of Corona Virus Disease-2019 (COVID-19) pandemic and social isolation process on individuals' nutritional behaviours and body weight changes. DESIGN: Retrospective cohort study. SETTING: Nutritional behaviours of the participants before the COVID-19 pandemic and in the social isolation process were evaluated with the Three Factor Nutrition Questionnaire. The changes in individuals' body weight during this period were also evaluated. PARTICIPANTS: A total of 1036 volunteer individuals (827 women, 209 men) aged 18 years and over participated in the study. RESULTS: During the COVID-19 pandemic and social isolation process, there was an increase in emotional eating and uncontrolled eating behaviours of individuals, but no significant change in cognitive restriction behaviour occurred (P = <0·00; P = <0·00 and P = 0·53, respectively). It was reported that the body weight of 35 % of the individuals who participated in the study increased during this period. CONCLUSION: Social isolation process practiced as a result of COVID-19 pandemic may lead to changes in some nutritional behaviours. Some precautions should be taken to prevent this situation that occurs in nutritional behaviours from causing negative health problems in the future.
