- Objectives
This study aims to compare changes in physical factors, health behaviors, eating habits, and nutritional intake among Korean male and female adults over a period of three years (2019–2021) before and after the outbreak of coronavirus disease 2019 (COVID-19).
Methods
This study utilized raw data from the 8th Korea National Health and Nutrition Examination Survey (2019–2021). The participants in this study included 6,235 individuals in 2019, 5,865 individuals in 2020, and 5,635 individuals in 2021. Individuals whose daily energy intake was less than 500 kcal or exceeded 5,000 kcal were excluded from the study.
Results
In comparison to 2019, overweight/obesity rates, weight, waist circumference, weekend sleep hours, and resistance exercise days/week increased in both male and female during the COVID-19 pandemic. Regarding eating habits, the proportions of people skipping breakfast, not eating out, consuming health supplements, and recognizing nutritional labels increased in 2020 and 2021, whereas the rate of skipping dinner decreased. Total energy intake has continued to decrease for the two years since 2019. A comparison of nutrient intake per 1,000 kcal before and after the outbreak of COVID-19 revealed that intake of nutrients, including protein, phosphorus, iron, vitamin A, riboflavin, and niacin increased, while folic acid intake decreased. In male, calcium, phosphorus, riboflavin, and niacin intakes increased, whereas iron, vitamin C, and folic acid intakes decreased. In female, phosphorus, iron, vitamin A, and riboflavin intake increased significantly, while protein and niacin intake decreased significantly.
Conclusions
After COVID-19, the obesity rate, breakfast skipping rate, health supplement intake, and nutritional label use increased, while the frequency of eating out, dinner skipping rate, and total energy intake decreased. These environmental changes and social factors highlight the need for nutritional education and management to ensure proper nutritional intake and reduce obesity rates in the post-COVID-19 era.

- Gallstone composition has changed over the past decades in the Korean with a prominent increase in the prevalence of cholesterol gallstone. This trend is possibly due to the westernization of dietary habits. The purpose of this study was descriptive of GB patient's health related eating behaviors and nutrient consumption patterns. One hundred and six gallstone patients who have had cholecystitis surgery enrolled in this study. Anthropomertic indices, such as height, weight, waist circumference, and hip circumference were measured and calculated BMI and WHR. As the biomarker, TC, TG, LDL-C, HDL-C, FBG level and SBP/DBP were measured and analyzed the relationship with GB stone formation. The structured checklist of health related eating behavior and the semiquantitative food frequency questionnaire after pre-test was used in the face to face interview study. The mean age was 54.9 +/- 13.3 and gallstone disease was more frequent in the fifties and sixties. Mean BMI was 24.3 +/- 2.8 in males, and 23.4 +/- 3.9 in females, the average of waist circumference was 91.1 +/- 7.0 cm in males and females were 85.4 +/- 9.6 cm. The WHR of men and women was 0.93 +/- 0.0, 0.90 +/- 0.1, respectively. The obesity and overweight trend was observed in gallstone patients. The mean blood sugar was researched at 114.5 +/- 35.0 mg/ dL. And the ratio of both symptoms DM and gallstone was 26.4%. The rate of dramatic eating repast was significantly higher in the females (p < 0.01). Males tended to more frequently consume meat, of high fat content meats and greasy food consumption when eating out. The CPF ratio was 57 : 16.5 : 26.5. There was a significant positive correlation between WC and energy (r = 0.252, p < 0.05), carbohydrate (r = 0.255, p < 0.05) and niacin (r = 0.227, p < 0.05). In addition, carbohydrate were significantly correlatied with TC (r = 0.230, p < 0.05). BMI appeared positive in correlation of protein (r = 0.201, p < 0.05) and fat (r = 0.205, p < 0.05). These findings provide a little association that dietary habits are related with cholesterol gallstone formation.
