Changes in dietary habits and association with lifestyle during the coronavirus disease 2019 (COVID-19) lockdown in the Kosovo population have not been studied yet . Therefore, the intent of the present study was to determine whether if COVID-19 lockdown had any impact in lifestyle, including dietary habits and physical activity (PA) patterns of people from different areas of Kosovo . Dietary habits, PA, body weight and sociodemographic variables were measured through validated online survey started one week after lockdown decision and lasted for next two month (May and June 2020). Six hundred eighty-nine participants (women 79% and men 21 %) aged between 20 and 65 years from the Kosovo territory participated in the research . Multivariate models showed that participants in family home residence, participants from Gjilan, participants female and participants with professional educations reported a higher likelihood of turning into a higher adherence to the Mediterranean diet (MedDiet) (OR : 6.09 , 5.25 , 5.17 , 4.19, respectively). The weight gained during the lockdown was positively associated with a higher cooking frequency (OR; 2.90, p <0.01), lower meat and fish consumption (OR; 1.15, p = 0.02; OR; 1.04, p = 0.04, respectively), higher fast-food consumption (OR; 0.49, p = 0.02) and no physical activity performance (OR; 0.43, p = 0.02) during the COVID-19 lockdown . The dietary habits during COVID-19 lockdown could be related to the improvements in adherence to the MedDiet and physical activities that may minimize related health complications.
