OBJECTIVES OF THE STUDY: The goals of this research were to investigate the eating habits and physical activity of adults from the Split-Dalmatia and Osijek-Baranja counties during the COVID-19 pandemic, to examine their experiences and opinions regarding the COVID-19 pandemic, and to assess whether there is a connection between the observed variables. STUDY STRUCTURE: Cross-sectional study SUBJECTS AND METHODS: Adults (18-64 years old) from Split-Dalmatia and Osijek-Baranja counties were included in the research. 300 respondents of both sexes were included. They filled out a fifteen-minute anonymous questionnaire online in the period from May 2 to June 10, 2022. RESULTS: In the research, no difference was observed regarding the change in body weight and increased food consumption, although the preponderance is on the side of men. Snacks were not consumed more often than usual, but at most once a day. Cooking was not more frequent, and breakfast was mostly represented. Male respondents drink far more water than women, 1.5 L of water and more per day. Coffee is represented more than once a day, and other food and beverages from once a day to occasionally. Intense physical activity is present in men, compared to women who mostly do not have it. Moderate physical activity is at most twice a week for men, mostly never for women. Walking and sitting are equally represented in men and women. CONCLUSION: The conducted research revealed a significant difference in the amount of water drinking, where men drink much more water (1.5 L and more per day). In the diet, only coffee is represented more than once a day. Intense physical activity is present in men, while it is mostly absent in women. There is no notable difference between sexes in other variables.
