This study examined changes in dietary life and dietary life satisfaction in one-person households during the COVID-19 pandemic. Using a sample of 916 one-person households from the Food Consumption Behavior Survey, we applied ANOVA and a system of equations model for our analysis which produced four main results. Firstly, during the COVID-19 pandemic, eating homemade and delivered meals increased, whereas eating restaurant, group, and HMR meals decreased. Eating breakfast and regular eating habits also increased during the pandemic. Secondly, approximately 30% of the sample reported increased expenditure on fresh food and HMR meals. The proportion of positive changes in dietary life was also greater than negative changes, and dietary life satisfaction was about three times higher than it had been before the pandemic. Thirdly, having breakfast and regular eating fully mediated the relationship between spending on fresh food and dietary life satisfaction, as well as the relationship between HMR purchases and dietary life satisfaction. Changes in expenditure on fresh food and HMR meals positively affected dietary life satisfaction through eating breakfast and regular eating. Fourthly, increased consumption of delivered food had a positive direct effect on dietary life satisfaction. Among sociodemographic variables, gender, education, occupation, and age were also significantly related to changes in dietary life satisfaction.
This study aimed to identify the need for dietary management due to weight changes among middle-aged women in the Gwangju area during the COVID-19 pandemic. To achieve this, a survey was conducted of their eating habits, dietary and lifestyle habits, alterations in food intake, and changes in menopausal symptoms. Overall, significant differences were found between dietary and lifestyle habits (p<.01) depending on the frequency of eating out. Specifically, those who eating out two to three times a week exhibited a significant increase in negative habits such as ordering delivery food and consuming instant meals. In terms of food consumption changes, those who eating out two or three times a week displayed a relatively higher increase in the consumption of non-recommended food than those who eating out once a week. Regarding changes in menopausal symptoms, individuals who eating out two to three times a week experienced a greater increase in the severity of menopausal symptoms than those who eating out once a week. In terms of dietary and lifestyle habit changes, it was found that the more frequent the exercise, the greater the overall improvement in dietary and lifestyle habits (p<.001). Moreover, women who did not experience weight gain exhibited positive changes in their dietary and lifestyle habits compared with women who experienced weight gain. The results for food consumption changes revealed that the consumption of non-recommended foods was higher in middle-aged women who experienced weight gain, particularly the consumption of meat (p<.001) and noodles (p<.05).
Objectives: This study aimed to assess the adherence to dietary guidelines among college students in the post-COVID-19 era and examine the changes in their dietary habits as the learning environment transitioned from remote to in-person classes. Methods: We conducted a survey involving 327 college students in Daejeon from March to April 2023. The survey questionnaires included various factors, including age, gender, type of residence, frequency of use of delivery food, convenience food, and eating out. In addition, we investigated the extent of adherence to the dietary guidelines for Koreans and the degree of dietary changes following the post-COVID-19 shift in class format were investigated. For comparative analysis of the level of adherence to dietary guidelines in relation to dietary habit changes, an ANOVA and a post hoc Scheffe test were employed. We also performed a multiple linear regression analysis to identify dietary factors influencing the level of adherence to dietary guidelines. Results: The study revealed a high rate of convenience food consumption and a low rate of homemade food intake among students. There was a marked increase in the consumption of processed foods, convenience foods, dining out, sweet foods, high-fat fried foods, beverages, and alcohol following the transition from online to in-person classes. When examining adherence to Korean dietary guidelines, the highest scored practice was 'Hydration', and the lowest was 'Breakfast habit'. Increased consumption of convenience foods, late-night snacks, and dining out were negatively correlated with adherence levels to dietary guidelines, specifically correlating with 'Healthy weight', 'Hydration', 'Breakfast habit', and the total score of adherence. The adoption of 'regular meals' was positively associated with increased adherence levels to dietary guidelines. Conclusions: The transition from remote to in-person classes post-COVID-19 led to increased intake of convenience foods, dining out, sweet foods, high-fat fried foods, and alcohol. The rise in convenience food and late-night snack consumption negatively influenced several aspects of the dietary guidelines adherence, thereby suggesting the need for strategies to encourage healthy dietary habits among college students.
Over the past few decades, changes in patterns of behavior (e.g., diet, smoking, alcohol consumption, and physical activity) have led to major changes in health status, characterized by increases in obesity, Type II diabetes mellitus, cardiovascular disease, and some cancers. This epidemiologic transition is largely the result of rapid increases in immigration to developed countries and rural-urban migration within developing countries, which is usually accompanied by environmental and lifestyle changes. In particular, adoption of “Western” dietary patterns, which tend to be high in fat and low in fruits and vegetables, is of concern since diet is a potent contributor to chronic disease risk. However, until recently, the process by which immigrants and rural-urban migrants adopt the dietary practices predominant in their new environments, known as dietary acculturation, has received very little research attention. Dietary acculturation is multidimensional, dynamic, and complex, and varies considerably depending on a variety of personal, cultural, and environmental characteristics. Therefore, to intervene successfully on the negative aspects of dietary acculturation, it is important to understand the process and identify factors that predispose and enable it to occur. The purpose of this article is to provide a practical model for understanding and investigating the effect of dietary acculturation on food and nutrient intake. Thus, this report 1) gives an overview of acculturation, 2) defines dietary acculturation and presents a model for how it occurs, 3) discusses measurement issues around dietary acculturation,4) reviews the literature on dietary acculturation in Korean Americans; 4) suggests a paradigm for acculturation research; and 5) offers some recommendations for future research in this area.
This study was to investigate the changes in dietary practices, reasons for making dietary changes, current food consumption patterns, and eating habits. Data were collected from 515 parents whose children were attending an elementary school and a middle school in Kimcheon. Among the twenty food groups studied, subjects reported eating more fruit, vegetables, lower-fat meats, high-fat meats, reduced/skim milk, and eggs and less sugar, fats, rice, salt, potato/sweet potato, and chicken. The changes in dietary practices except high-fat meats and salt were significantly different between sex, age, education level, income level, or BMI groups. The primary reason for making dietary changes was 'concerned about family's health'. The average rate of never eating breakfast or less than 2 times per week was found to be 23.2% with a greater rate in younger age group. The rate of breakfast skipping was found to vary between different age and education groups. The regularity of mealtime and overeating practices were significantly different between age groups. Eating out practices were found to vary between different age, education, and income groups. People at younger age group in Kimcheon should be targeted for nutrition education about eating habits. These findings are applicable at the planning and implementation stages of various nutritional improvement projects.
BACKGROUND/OBJECTIVES: The coronavirus disease 2019 (COVID-19) outbreak has dramatically changed nearly every aspect of our lives. Although Dietary lifestyle includes attitudes and behaviors to meet their most basic needs, but few studies have examined the pattern of changes in dietary lifestyle driven by COVID-19. This study explores changes in dietary attitudes and behaviors among Korean consumers after COVID-19. SUBJECTS/METHODS: An online survey was conducted with 549 Korean adults aged 20 and older to identify general demographics and changes in dietary attitudes and behaviors. Data were collected from Oct 12 to Oct 18, 2020. Frequency, percentage, and mean values were calculated and a K-means cluster analysis was performed to categorize consumers based on the 5S of dietary attitudes (i.e., savor-oriented, safety-oriented, sustainability-oriented, saving-oriented, and socializing-oriented). RESULTS: Findings indicate consumers considered safety, health, and freshness to be most important when choosing groceries and prepared meal such as home meal replacement and delivery food. Among the types of services, a large proportion of consumers increased their delivery and take-out services. Regarding retail channels, the increase in the use of online retailers was remarkable compared to offline retailers. Finally, consumers were classified into four segments based on changes in dietary attitudes: "most influenced," "seeking safety and sustainability," "abstaining from savor and socializing," and "least influenced." Each type of consumer exhibited statistically significant differences by sex, age, household composition, presence of disease, and perceived risk of COVID-19. CONCLUSIONS: This exploratory study provides initial insights for future research by identifying various aspects of dietary attitudes and behaviors among Korean consumers after COVID-19.
This study was conducted to investigate the changes of dietary attitudes and behaviors in relation to the use of computers of elementary school children in Seoul. The total of 451 elementary school children, consisting of 235 females and 216 males, participated in the study. The result of domestic characteristics, dietary attitudes and behaviors, the level of the use of computers, and health-related symptoms of the subjects were achieved through the questionnaires as follows: The average height, weight, BMI and obesity-index of the participants were 149.0 cm, 42.4 kg, 19.0, -8.6, respectively. Anions subjects, 42.8% answered their bed times were between 11~12 pm, and 82.4% answered that they had extracurricular activities. The most desired activity as their leisure was computer works (female: 44.3%, male: 62.5%). 38.4% of children used the computers for 1~2 hours a day and the most general usage of computers was a computer game (66.1%). The changes in dietary habits of the subjects were such as eating faster(30.2%), having lots of snacks(28.8%), eating anything at hand(26.4%), skipping breakfast due to over-sleeping(18.4%). As changes in life patterns, those in the time managements for watching T.V.(35.3%), reading(35.0%), exercising(31.9%), sleeping(27.5%), relaxing(27.5%) and other hobbies(26.4%) were observed. In conclusion, many children were being affected by the socioeconomic factors changing the environments, especially by the need for the use of computers. The rates of eating alone and skipping breakfast were getting higher in the dietary patterns of elementary school children. We found that the changes in social environments according to the heavy use of the computer were affecting on their dietary pattern. The direction and method of nutrition education had to be established for the proper understanding of the desirable dietary behaviors.
This study examined the factors related to stages of dietary behavioral changes among 1449 child bearing aged women (mean age $\pm$ SD = 25.6 $\pm$ 5.3 years) residing in large cities. A self administered questionnaire was used to assess stages of dietary behavioral change, meal balance and regularity, food availability, nutrition knowledge, body mass index, nutrient intake, and psycho-social factors including self efficacy, perceived benefits and barriers, social modeling. Undesirable dietary behaviors (precontemplation and contemplation) were shown among 45.1-57.4% of the participants, among those, 33.4-43.0% were precontemplators. Participants' self efficacy scores associated with dietary changes were higher in specific situations (3.42) as compared to general situations (2.86). Similarly, they appeared to perceive more benefits (3.86) rather than barriers (2.76) by changing their inappropriate eating habits. Perception and accuracy scores of nutrition knowledge were relatively high, indicating 90.9 and 80.1, respectively. In terms of food availability at home, fresh fruits received the highest score, followed by milk and milk products, vegetables, meat, alcoholic beverages and soft drinks. In social modeling assessment, family members, as compared to friends, appeared to have better dietary habits. Stages of dietary behavioral change assessed in terms of meal regularity were associated with nutrient intake, showing higher energy and carbohydrate intakes but lower fat intake among those who belonged to the action and maintenance stage. They also presented higher self efficacy and perceived more benefits and less barriers regarding the change of undesirable eating habits. Fresh meat and vegetables were more available among those maintaining desirable dietary habits. Results of this study presented the significant relations of motivational and reinforcing social factors with stages of dietary behavioral changes and a need for the development of tailored nutrition education program considering these factors for child-bearing aged Korean women.
In this study, we investigated the effects of lowering the fat and cholesterol in the diets of 26 Korean hypercholesteolemic men($\geq$240mg/dl). They consumed 2378kcal/day with 20.9% of the energy deriving from fat, and a cholesterol intake of 282mg(118mg/1000kcal). The experimental diet consisted of 2400kcal, the same as their usual diet, but the fat content was restricted to 15%, and the cholesterol level to below 100mg/1000kcal. The subjects kept to this diet for four weeks and were asked to maintain their usual life activities during the experimental period. The dietary intake and levels of plasma lipid, lipoprotein-cholesterol and apoprotein of the subjects were analyzed before, two weeks into, and after four weeks dietary intervention. After two of the dietary intervention, there were no significant changes of plasma total cholesterol or triglyceride levels but there was some changes of phospholipid level. However, after four weeks, the levels of plasma total cholesterol, triglyceride, and phospholipid had decreased significantly: 18.2%, 32.9%, and 11.9%, respectively. And the LDL-cholesterol and VLDL-cholesterol levels also showed a marked reduction of 18.1%, and 33.0% respectively without change of HDL-cholesterol level. There were no changes in the levels of Apo-A 1, Apo-B, or Lp(a). The changes of the plasma lipid levels were significantly associated with the changes in dietary fat intake but not the cholesterol intake. In conclusion, although the responses to the dietary intervention varied among the individual subjects, the lowering of dietary fat component from 21% to 15% of energy intake seems to be an effective way to reduce plasma cholesterol and triglyceride levels without decreasing HDL-cholesterol level. It was also found that the restriction of dietary cholesterol to below 100mg/1000kcal not seem to be effective for the hypercholesterolemic patient who already consuming below 300mg/day of cholesterol.
In Korea, there is an urgent need to identify nutrition-related risk factors for obesity, because the prevalence of these conditions continues to rise among Koreans. While some studies suggest that westernized dietary pattern may increase the risk of obesity, others do not support these findings. Longitudinal studies examined the role of dietary patterns in relation to changes in body fat composition. Nowadays rapid changes in dietary patterns are related to socioeconomic status and westernized diet. Major dietary changes include a large increase in the consuming of at in the diet and a fall in total cereal intakes and fiber. This research showed remarkable decline in the consuming proportion of the grains and vegetables. These results fit closely with the trend toward increased prevalence of obesity in Korea. Most longitudinal studies on these relationships among children and adults showed that the dietary patterns affected obesity. In conclusion, we need programs to promote healthy Korean diet pattern in Korea.
