Abstract PDF PubReader ePub: Objectives
The total population of Korea began to decline in 2019; in particular, the population in rural areas has been rapidly decreasing and is aging. Therefore, the government has designated depopulation areas and is seeking ways to support them. To assess whether health disparities exist between areas with population decline and those without, this study used community health survey data to observe temporal changes in health behaviors between the two types of areas. Methods: The analysis used Community Health Survey data from 2010 to 2019, and regional classification was divided by depopulation areas designated by the Ministry of the Interior and Safety. Trends in health behavior and chronic disease prevalence between depopulation and non-depopulation areas were analyzed. All analyses were conducted using complex sample analysis procedures in SAS 9.4 software. Results: The smoking rate steadily decreased in both depopulation and non-depopulation areas, whereas the high-risk drinking rate increased slightly. The walking practice rate did not improve in depopulation areas compared to non-depopulation areas. Furthermore, nutritional labeling usage rate was consistently lower in depopulation areas than in non-depopulation areas, with the gap being the largest. The prevalence of obesity, diabetes, and hypertension showed that the gap between depopulation and non-depopulation areas is continuously increasing. Conclusions: Health behaviors in depopulation areas have not improved, and the prevalence of chronic diseases is increasing rapidly. Therefore, the demand for health care services that support healthy lifestyle practices and chronic disease management in these areas is expected to increase.

Health behaviors and eating habits in people’s 20s and 30s according to food content usage level on social media: a cross-sectional study: Seo-Yeon Bang, Bok-Mi Jung; Korean J Community Nutr 2023;28(5):392-403. Published online October 31, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.5.392

Objectives
This study was intended to investigate adults’ health behaviors and eating habits according to their levels of social media use.
Methods
From May 27 to July 11, 2022, an online survey was conducted of 452 male and female social media users in their 20s and 30s, and their eating habits and health behaviors were compared and analyzed according to their degree of social media use. For each of the three levels of food content use, the frequency of social media content use, and the total score range of average social media viewing time per day were divided into three parts, and a group with a score of less than 2 points was classified as low-use; a group with a score of 2 or more and less than 3 points was classified as middle-use; and a group with a score of 3 points or more was classified as high-use.
Results
The use of food content was higher in women than in men (P < 0.001), and higher in those in their 20s than in those in their 30s (P < 0.001). The group with a high level of food content use showed a higher rate of post-use hunger than the group with a low level (P < 0.01). The experience of eating after using food content was also higher in the group with a high level of use than in the group with a low level of use (P < 0.001). The group with a normal or high level of food content use had more negative eating habits than the group with a low level.
Conclusions
The study highlighted the need to provide desirable food content to people in their 20s and 30s with negative eating habits and to promote them so that they can use the right healthy nutrition–related content.

A Comparative Study of the Dietary Behavior of Adults Aged 20 and Over according to the Mukbang Viewing Time: Ha-Yan Nam, Bok-Mi Jung; Korean J Community Nutr 2021;26(2):93-102. Published online April 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.2.93

Abstract PDF

Objectives
This study was conducted to investigate the relationship between watching Mukbang (eating broadcasts) and dietary and health behavior in adults who watch Mukbang Methods: The questionnaire was administered on a self-written basis through online and offline formats to 800 adults (400 men and 400 women). The contents of the survey consisted of general characteristics, Mukbang viewing time per week, breakfast intake frequency, preference for menus when viewing Mukbang , delivery food intake frequency per week, late meal intake frequency per week, and health behavior. The subjects were divided into three groups according to Mukbang viewing time.
Results
The body weight of viewers was significantly higher whenMukbang viewing time was over 14 hours for both men and women. In particular, based on the BMI (body mass index), those who watched Mukbang for more than 14 hours were found to be overweight. People with more than 14 hours of Mukbang viewing time per week were found to prefer mostly carbohydrate-rich food and meat, while those with less than 7 hours of Mukbang viewing time per week showed a higher preference for vegetables and fruits. An analysis of the frequency of breakfast eaten showed that the rate of skipping breakfast was the highest for those who watched Mukbang for more than 14 hours per week, and the rate of eating breakfast daily was the highest in the case of fewer than 7 hours of viewing. In the case of high Mukbang viewing time per week, the frequency of food delivery and night eating was high. When Mukbang viewing time was high, the viewer’s interest in health was low and the frequency of exercising too was low.
Conclusions
Viewers with high Mukbang viewing time showed undesirable health and eating behavior. Thus, it is believed that proper nutrition education on improving eating habits and raising the awareness of correct eating habits is necessary for such viewers.

Published online April 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.2.122

Abstract PDF

Objectives
This study evaluated the dietary habits and health behaviors of Korean adults according to their physical activity. Methods: Adults aged 19~64 years, who participated in the 2016~2018 National Health and Nutrition Examination Survey, were enrolled in this study. The subjects were classified into the physical inactivity group, aerobic physical activity group, strength exercise group, and combined exercise group. Results: Significant differences in skipping breakfast, frequency of eating out, dietary supplements, and alcohol drinking status were observed among physical activity groups (P < 0.001). The combined exercise group had the highest % KDRI of protein, vitamin A, thiamin, riboflavin, niacin, calcium, potassium, and iron (P < 0.001). The physical inactivity group had the highest obesity rate (35.1%), and they perceived their body image type to be obese. In the combined exercise group, 47.8% of respondents said they were in good health (P < 0.001). The health-related quality of life score of the physical inactivity group was the lowest, with a score of 0.94. The metabolic syndrome risk rate of the combined exercise group was lower at 0.62 times (95% CI, 0.51-0.75) than the physical inactivity group. Conclusions: The physical activity type was associated with metabolic syndrome. These results can be useful for supporting dietary education and physical activity programs for adults.

Abstract PDF

Objectives
This study investigated the health and nutritional status of the elderly according to the number of chronic diseases, using data obtained from the Korea National Health and Nutrition Examination Survey 2013~2015. Methods: Data from a total of 2,310 individuals, aged 65 years and over, were used for the analysis. The elders were divided into 0 (n=375), 1 (n=673), 2 (n=637) and 3 or more (n=625) groups, by considering the number of chronic diseases. Results: Compared to other groups, the elderly subjects who were living with their spouse had the highest ratio in group 0 (P < 0.05), whereas subjects without economic activities had highest ratio in 3 or more group (P < 0.05). The EQ-5D index of subjects in the 0 group (0.90 ± 0.01) was higher than that in the 3 or more group (0.86 ± 0.01) (P< 0.05). After adjusting for confounding factors, the energy intake of subjects was determined to be lowest in the 3 or more group (P < 0.05). Protein (P < 0.05) and riboflavin (P < 0.05) intakes of the 3 or more group were also lower than other groups. Conclusions: This study indicates that multimorbidity of the elderly is associated with their health and nutritional status. The nutrients intake of the elderly, especially energy, protein and riboflavin, tended to be lowest in the 3 or more group. Further research is required to elucidate the risk factors related to presence of multimorbidity in the elderly.

Consumption Behaviors of Energy Drinks and Comparison of Associated Factors Among College Students in Gwangju: DaWun Seo, Bok Hee Kim; Korean J Community Nutr 2018;23(4):289-301. Published online August 31, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.4.289

Abstract PDF PubReader

OBJECTIVES
The aim of this study was to examine the current status of consumption of energy drinks among college students and investigate the effects of general environmental factors, health behavior factors, caffeine knowledge levels, and perceived stress levels on consumption of energy drinks.
METHODS
A survey was conducted among a total of 479 college students in Gwangju, using self-administered questionnaires. The questionnaire consisted of items about general environmental factors, health behavior, caffeine knowledge, perceived stress, and energy drink consumption behaviors.
RESULTS
69.1% of participants experienced consumption of energy drinks, and specifically 82.8% of male students and 54.1% of female students experienced consumption of energy drinks (p < 0.001). The reasons for drinking energy drinks were found to be recovery from fatigue, curiosity, taste, habit, thirst relief, and stress relief. In addition, 40.7% of participants experienced drinking energy drinks mixed with alcohol, and specifically 48.6% of male students and 27.4% of female students reported drinking energy drinks with alcohol (p < 0.001). Moreover, 51.5% of participants responded that they experienced the effects of energy drinks, 31.9% reported experiencing adverse effects, and 41.1% were found to perceive the health risks. As a result of the assessment of caffeine knowledge, the participants showed a high level of knowledge of the arousal effect (77.7%) and the concentration increasing effect (70.8%) of caffeine, whereas they exhibited a low level of understanding of the health problems due to caffeine (32.6%) and adequate caffeine intake levels (24.4%). The higher levels of consumption experience of energy drinks was associated with higher body mass indexes (BMI) (p < 0.01), higher academic years (p < 0.01), lower levels of interest in health (p < 0.05), smoking (p < 0.001), alcohol consumption (p < 0.05), and higher levels of perceived stress (p < 0.05).
CONCLUSIONS
The risk groups related to consumption of energy drinks among college students were identified as male students rather than female students, students in the third or fourth year of study associated with increased stress levels, and students with negative health behaviors. Therefore, support for diverse health and nutrition education for college students is required along with the improvement of internal and external environments of schools in order for college students to manage increased stress levels due to the schoolwork and preparation for employment and maintain positive health behaviors.

Health Behavior Factors Associated with Sugar-sweetened Beverage Intake among Adolescents: Hyae Min Gu, Jong Park, So Yeon Ryu; Korean J Community Nutr 2018;23(3):193-201. Published online June 30, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.3.193

Abstract PDF PubReader

OBJECTIVES
This study was conducted to measure the intake rate of SSBs (sugar sweetened beverages) and examine the relationship between health behavior factors and SSBs intake by adolescents.
METHODS
This study used data from the 2016 Korea Youth Risk Behavior Web-based Survey, which included 65,528 study participants. SSBs intake frequency was measured by asking respondents if they consumed soda, high-caffeinated beverages, and sugary drinks during the previous week. Type of intake was categorized into three groups according to the number of consumed drinks [SSBs (0): None; SSBs (1â€“2): 1 or 2 consumed; SSBs (3): 3 consumed]. Multinomial logistic regression analysis was used to examine health behaviors that affected SSBs consumption.
RESULTS
Increased SSBs intake was significantly correlated with current smoking (OR=2.4, 95% CI=1.82â€“3.17), current drinking (OR=2.13, 95% CI=1.82â€“2.51), sedentary time increase (OR=1.31, 95% CI=1.15â€“1.49), three days or more physical activity per week (OR=1.12, 95% CI=1.02â€“1.24), < 8 hours sleep (OR=1.6, 95% CI=1.43â€“1.78), increased internet usage time (OR=1.44, 95% CI=1.25â€“1.65).
CONCLUSIONS
Sugar-sweetened beverages intake by Korean adolescents was associated with health behaviors such as smoking, drinking, sedentary time increase, more physical activity, poor sleeping time, and increased internet use time. Based on these results, it is necessary to recognize the influence of SSBs intake and to intervene to reduce consumption of SSBs.

Use of Dietary Supplements and Determinants of Taking Dietary Supplements by Gender in the Korean Population: Using the 4(th) Korean National Health and Nutrition Examination Survey (2007-2009): Yun Jung Lee, Minji Kang, Hee Young Paik, YoonJu Song; Korean J Community Nutr 2017;22(4):347-355. Published online August 31, 2017; DOI: https://doi.org/10.5720/kjcn.2017.22.4.347

Abstract PDF PubReader

OBJECTIVES
Although dietary supplements use in Korea has been rapidly increasing and women are more likely to take dietary supplements more than men, only a few studies have been conducted to investigate factors contributing to gender differences in dietary supplement use in the Korean population. The aim of this study is to evaluate the prevalence of dietary supplement use and also identify gender-specific key factors that contribute to it using the data of the 4th KNHANES.
METHODS
Subjects were divided into user and non-user groups according to the answer given to the question that asked whether they had used any dietary supplement for more than 2 weeks on a regular basis during the previous year. Factors related to dietary supplement use were examined by general characteristics, health behavior and eating behavior.
RESULTS
Prevalence of dietary supplement use was 13.6% for men and 20.6% for women. Users were more likely to be middle-aged, have higher income and education, have a spouse, or reside in dong areas in both men and women. Regarding health behaviors, men with desirable lifestyle behavior were more likely to take dietary supplements, while men who smoked were less likely to take dietary supplements. Regarding disease history, both men and women with a current disease had higher odds of taking supplements. With regard to dietary behavior, frequent eating out and nutrition attitude were associated with higher odds of taking supplements in both men and in women.
CONCLUSIONS
Health or dietary behavior related factors that were associated with taking supplements differed by gender. These findings can be useful for planning gender-specific dietary education and health programs.

Abstract PDF PubReader: OBJECTIVES
The study was performed to investigate the relationship between snack intake and oral health behavior in middle school students in Gyeonggi-do area.
METHODS
The survey questionnaire was recorded by middle school students from July 6 to August 24, 2011. The questionnaire included items on general characteristics, snack intake status, and oral health behavior. Among collected survey questionnaire, a total of 620 questionnaires (320 males and 300 females) were analyzed using SPSS 15.0 program.
RESULTS
Frequencies of snack and beverage intakes were significantly higher in males than in females (p < 0.001). Oral health behavior was significantly higher in students with lower snack intake compared to those with higher or average snack intake (p < 0.05). Oral health behavior for tooth brushing and toothbrush care were significantly higher in females than in males (p < 0.05).
CONCLUSIONS
Oral health behavior score that reflected better oral health of the subjects were higher as the snack intake was lower. Oral health behavior score was higher in females than in males. We conclude that the contents for oral health and nutrition education focused on snack intake need to be developed to induce changes in oral health behavior in middle school students.

Comparison of Health Belief Levels and Health Behavior Practices according to Lifestyle among Adults Residing in Seoul: Na Hong Choi, Hong Seok Ahn, Seungmin Lee; Korean J Community Nutr 2011;16(6):683-696. Published online December 31, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.6.683

Abstract PDF PubReader

This study compared levels of health beliefs and health behavior practices according to lifestyle pattern among adults in Seoul. A self-administered survey questionnaire was collected from a total of 1,004 Seoul residents aged 30-59 years. The levels of perceived benefit, perceived barrier, and self-efficacy from health belief model and health behavior practices were measured across multiple health behavior areas including dietary behavior, drinking, smoking, exercise, functional food consumption, and weight control behavior. Factor analysis and subsequent cluster analysis based on 28 lifestyle questions divided the subjects into four lifestyles of society-, economy-, trend-, and health-oriented lifestyle. Some general characteristics were significantly different by lifestyles. The society-oriented lifestyle was significantly higher in proportions of men and overweight. The trend-oriented lifestyle was significantly younger and spent more monthly allowance. Health-oriented lifestyle was older. The levels of health belief variables and health behavior practices significantly differed by lifestyles. Overall the health-oriented lifestyle showed more desirable levels of health belief variables and health behavior practice in various health behavior areas compared to the other lifestyles, whereas the society-oriented lifestyle was found the other way. Health belief model variables including perceived benefit, perceived barrier, and self-efficacy were generally significant in predicting the levels of various health behavior practice, with somewhat differences by lifestyle pattern and health behavior type. The study findings suggest it may be useful to segment target subjects according to lifestyle pattern in planning and administering health education programs.

Antioxidant Nutrient Intakes and Health Behaviors of Rheumatoid Arthritic Patients: Ju Hee Lee, Eun Jung Chung, Young Ho Lee, Jong Dae Ji, Hong Seok Ahn; Korean J Community Nutr 2008;13(2):253-262. Published online April 30, 2008

Abstract PDF: Previous studies have indicated that incidence of rheumatoid arthritis (RA) is partly related to the damage of antioxidant systems, but etiology of RA is not fully identified. This study was performed to evaluate nutrient intakes including antioxidants, health related behaviors and food habits of RA patients and controls. RA patient group (n = 68) and sex-matched healthy controls (n = 68) were joined in this study. Nutrient intake was estimated using a semiquantitative food frequency questionnaire. As mean age of RA (52.9 +/- 13.8 years) was significantly higher than those of controls (48.7 +/- 5.9 years), data were analyzed by using Student's t-test, adjusted for age. There was no significant difference between two groups in body mass index. Compared with those of controls, frequencies of drinking (p < 0.001) and coffee consumption (p < 0.05) of RA groups were lower. RA groups had lower frequencies of fruit (p < 0.01), vegetable (p < 0.05) and fatty meat (p < 0.05) consumptions and balanced diet (p < 0.01), and higher frequencies of fried dishes (p < 0.01), and salty dishes (p < 0.01), compared to controls. The most nutrient intakes including energy intake of RA were tended to be lower than those of controls. Vitamin A, beta-carotene and vitamin C intakes were significantly lower in RA than controls (p < 0.001). Daily vitamin A, beta-carotene and vitamin C intakes of RA were lower than those of control (vitamin A: RA 360.6 +/- 252.23 microgram RE, control 844.5 +/- 426.2 microgram RE, p < 0.001; beta-carotene: RA 1450.9 +/- 1019.0 microgram, control 3968.8 +/- 2248.21 microgram, p < 0.001; vitamin C; RA 40.6 +/- 21.48 mg,control 84.7 +/- 40.29, p < 0.001) These results suggest sufficient consumption of antioxidant nutrients may prevent and improve RA status.

Health-Related Behavioral Factors Associated with Nutritional Risks in Korean Aged 50 years and Over: Kyeong Sook Yim; Korean J Community Nutr 2007;12(5):592-605. Published online October 31, 2007

Abstract PDF: Undernutrition could be a significant deterrent to healthy aging and could negatively affect health outcomes in elderly. This study aimed to assess health-related factors which are associated with nutritional risks in middle-aged and elderly individuals by a cross-sectional study. Interviews were conducted with 2660 subjects (847 males, 1813 females), aged 50 years and over, in 15 cities in Korea. Data on food intake were obtained through a validated semi-quantitative food frequency questionnaires. Nutritional status were analyzed according to health-related factors including cigarette smoking, alcohol drinking, exercise, stress and depression level. Less regular exercise was associated with a higher likelihood of a poor nutrition [odds ratio (OR) 1.94; 95% confidence intervals (CI) 1.43-2.65] of middle-aged and elderly male subjects. Cigarette smoking (OR 1.84; 95% CI 1.24-2.71), less exercise (OR 2.58; 95% CI 2.07-3.21), stress (OR 1.73; 95% CI 1.36-2.22), and depression (OR 1.34; 95% CI 1.08-1.67) of middle-aged and elderly female subjects was associated with a higher likelihood of a poor nutrition. The results of the multiple regression analysis showed that less exercise proved to be the strongest predictors for the poor nutrition, followed by stress, smoking, and depression (model R2= 9.0%). It suggests that guidance to promote regular exercise, to quit smoking, to minimize stress and depression level might help to improve nutritional status of middle-aged and elderly in Korea. These findings also suggest that having recommendable health behaviors are beneficial to the good nutrition of subjects aged 50 years and over.

College Students' Dietary and Health Behaviors related to Their Myers-Briggs Type Indicator Personality Preferences: Byung Sook Kim, Young Eun Lee; Korean J Community Nutr 2002;7(1):32-44. Published online February 28, 2002

Abstract PDF: The objective of this study was to evaluate college students' dietary and health behaviors in relation to their Myers-Briggs Type Indicator (MBTI) personality preferences. Dietary and health behaviors were surveyed for 444 college students who performed the MBTI personality test. Only 6.1% of the subjects regularly had three meals a day, while 27.1% ate breakfast every day. Fifty-six point nine percent of the students took less than 15 minutes to eat a meal and had the habit of eating fast. The number of food groups they ate was, on average, 2.74 and was eaten mainly at dinner. This showed that college students did not eat a large variety of foods. Eighty-two percent of the subjects drank alcoholic beverages, 21.4% smoked, and 69.3% exercised. In addition, 73.9% of them were not satisfied with their body image, but they were not eager to try weight control. There were not many significant differences between Extraversion (E)-Introversion (I), Sensing (S)-iNtuition (N), and Thinking (T)-Feeling (F) in their dietary and heath behaviors, although some gender differences existed. Significantly better dietary and health behaviors were shown in subjects preferring Judging (J) rather than Perceiving (P). There behaviors included eating breakfast, regularly eating three meals a day, smoking less, exercising more and having a lower tendency to night-eating. The personality preference of J-P could be useful index for nutritional education and counseling or behavior modification programs for obese people.

The Relationship between Ophthalmic Refractive Errors and Factors of Nutrition and Health: Youngok Kim, Hae Jung Choi, Soon Young Lee; Korean J Community Nutr 2000;5(4):608-614. Published online December 31, 2000

Abstract PDF: The purpose of this study was to evaluate the relative importance among various biological and environmental factors on refractive errors. Various factors such as diseases, health related behavior such as drinking, smoking and exercise, as well as dietary factors were considered as a possible determinant. Surveys of 492 residents over 20 years of age in Kuri city were conducted during 1998. The survey included a refractive error test adopting a autokerato-refractometer, dietary survey using a 24 hour recall method, disease survey including blood and other diagnosis tests, and a health behavior survey using questionnaires with variables of smoking, drinking, and exercise. A stepwise logistic regression analysis was adopted to analyse the relative importance among independent variables of health behaviors, disease, and dietary factors on ametropias. As a result, in the case of myopia, liver dysfunction appeared to be the most important factors followed by the health related behavior of smoking and exercise as the second most important factors. Nutrient factors such as carotene and protein appeared to be the third most important factors. Similar results had been shown in the case of the hyperopia. In summary, liver dysfunction and the health related behaviors of drinking and smoking appeared to be more influential factors on abnormal eye sight of myopia and hyperopia than dietary factors.
