This study aimed to examine relationships of water and dietary fiber intake with various health-related factors using data from the 2016~2019 Korea National Health and Nutrition Examination Survey (KNHANES). A total of 8,419 adults aged 19~49 years were categorized into four groups: (1) sufficient intake of both water and fiber (Type 1) (n=2,235), (2) water deficiency with sufficient fiber (Type 2) (n=1,470), (3) fiber deficiency with sufficient water (Type 3) (n=1,031), and (4) deficiency in both water and fiber (Type 4) (n=3,683). General characteristics, body composition, health behaviors, dietary habits, nutrient and food intake, and dietary quality were compared. Type 4 had more female (p=0.028), older adults (p<0.001), and higher socioeconomic status (p<0.001) than Type 1. Type 1 consumed breakfast more frequently (p<0.001). Nutrition label recognition, usage of nutrition label, and all nutrient intakes were the highest in Type 1 but the lowest in Type 4. Type 1 also had better dietary variety score and nutritional quality. These findings highlight the importance of adequate water and fiber intake for balanced nutrition and suggest that targeted nutrition education is needed, especially for male and low-income groups with insufficient intake.

This study analyzed the status of agrifood consumer competencies and the factors influencing them to provide useful information to improve the quality of life by strengthening the agrifood consumer competencies. The raw data of the 2022 Consumer Behavior Survey for Food collected by the Korea Rural Economic Research Institute were used. The data from 3,321 responses were used for the final analysis. Among the competencies, the average score of the cognitive and practical competencies were 3.543 and 3.459 points, respectively. In addition, the average scores of the specific areas within cognitive competency were 3.587 points for dietary competency, 3.557 points for civic competency, and 3.489 points for purchasing competency. Within practical competency, the average scores of the specific areas were 3.569 points for dietary competency, 3.422 points for civic competency, and 3.392 points for purchasing competency. Gender, age, monthly household income, marital status, administrative district, interest in health, and interest in food safety issues were the significant factors affecting the specific areas within cognitive competency. On the other hand, gender, age, educational level, monthly household income, marital status, administrative district, interest in food safety issues, and each of the areas within cognitive competency had a significant impact on the specific areas of practical competency.

금융 인식, 금융 기능, 금융 행위는 건전한 금융 생활과 금융 웰빙을 달성하는 데 필요한 기초 역량을 구성하는 핵심 요소들이다. 본 연구는 한국금융소비자보호재단이 2020년과 2022년에 수집한 자료를 분석해 우리나라 성인의 금융 인식, 기능, 행위를 진단한다. 우리 나라 성인은 스스로 유혹에 잘 견디며, 장기 목표를 위해 부지런히 일할 수 있다고 생각하 며, 부를 쌓을 기회가 모든 사람에게 공정하게 주어져 있다는 데는 동의하지 않는 경향이 있다. 물질주의에 대한 인식은 조사 시점에 따라 유의한 차이를 보이고 있어 더 장기적인 추가 조사 결과를 통해 정확한 인식 상태를 파악할 필요가 있다. 금융 기능과 금융 행위에 대해서는 대체로 안정적이고 확고한 결과를 확인할 수 있다. 즉, 우리나라 성인은 금전 약속 을 지키기 위해서, 그리고 자신이 수립한 재무 목표를 달성하기 위해서 노력하고 있다. 더 신뢰할 만하고 정확한 조사 결과를 얻기 위해서는 설문조사 문항을 부정적으로 서술하는 대신에 가급적 긍정적으로 서술함으로써 응답자들이 실수로 그릇된 선택을 하지 않도록 설 계할 필요가 있다. 본인의 금융 지식이 풍부하다고 판단하는 성인이 많지 않으므로 금융교 육을 통해 성인의 금융 지식을 강화하는 노력도 요구된다.

Gaming disorder, also referred to as game addiction, has garnered increasing clinical attention and was officially recognized by the World Health Organization (WHO) in 2018. Previously categorized alongside behavioral addictions such as gambling, gaming disorder shares key characteristics, including compulsive engagement and persistent behavior despite adverse consequences. Psychological risk factors include high impulsivity, emotional dysregulation, and stress, often exacerbating mental health issues like depression and anxiety. Despite its global recognition, research on gaming disorder in Korean adults remains limited, leaving a gap in understanding how individuals exhibit traits associated with the disorder. This study aims to characterize the psychological traits of high-risk individuals for game disorder in Korea and compare them with low-risk individuals. Findings revealed that high-risk individuals are more prone to addictive behaviors such as internet addiction, binge eating, pathological gambling, and nicotine dependence, though not alcohol addiction. They were also characterized by higher impulsivity, lower self-control, and poorer emotion regulation, particularly a reduced use of cognitive reappraisal strategy. Furthermore, high-risk individuals reported elevated levels of stress, depression, and anxiety. These findings highlight potential risk factors for gaming disorder in adults and provide a foundation for developing targeted screening tools and early intervention strategies for at-risk individuals.

This study aimed to determine the association between household types and healthy dietary practices among Korean adults. A cross-sectional analysis was performed using nationwide data on 23,488 participants from the 2017-2021 Korea National Health and Nutrition Examination Survey (KNHANES). Based on self-reported data, the participant household types were classified into single- and multi-person households. The adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for healthy dietary practices according to household types were calculated by applying multivariable logistic regression analysis after adjusting for confounders. Of total, 11.21% and 88.79% were single- and multi-person households, respectively. Compared with individuals living in multi-person households, those in single-person households had lower odds of adhering to healthy dietary practices (AOR: 0.88, 95% CI: 0.79-0.98) and consuming adequate saturated fatty acids (<7% of energy) (AOR: 0.78, 95% CI: 0.69-0.88). In addition, men and individuals aged 65 years living in single-person households exhibited lower odds of consuming adequate saturated fatty acids and 500 g of fruit and vegetables per day than those in multi-person households. Single-person households often find it a challenge to practice a healthy diet. Hence, nutritional policies and educational support that help individuals living alone consume healthier diets are warranted.

This study investigated the association between dietary intake and 10-year risk for CHD predicted from Framingham risk score in Korean adults using the Korea National Health and Nutrition Examination Survey 2019-2020. Eight thousand subjects (3,382 men and 4,618 women) aged 30 years or older were classified into three groups according to the 10-year CHD risk (%). The sociodemographics, anthropometrics indices, blood profiles, and dietary intake were collected. After adjusting for confounding variables, the mean adequacy ratio (MAR) decreased for both men and women as the disease risk increased. The high–risk group was below the MAR criteria, indicating that the overall quality of the meal was not good. The highest consumers of legumes (OR 0.56, 95% CI 0.37-0.84), fruits (OR 0.67, 95% CI 0.48-0.93), and fish (OR 0.60, 95% CI 0.42-0.87) had a 44%, 33%, and 40% lower 10-year CHD risk than lowest consumers in men, respectively. In women, there is no significant relationship between food groups and disease risk. Therefore, improving lifestyle habits such as weight control, increased activity, and adequate food intake, especially legumes, fruits, and fish rich in antioxidant nutrients and bioactive substances, appears to have a potential association with preventing coronary heart disease in Korean adults.

This study aimed to provide directions and implications for a future program by analyzing studies on diabetes programs from 2000 to 2020. Among the studies with control and experimental groups, the selected studies included ones that provided intervention to patients with diabetes and ones that contained descriptive statistics. Sixteen studies were selected to verify the effectiveness and homogeneity of the data coding meta-analysis. The overall effect size in the diabetes program combined estimate was 0.398 (95% CI: 0.268, 0.425, p=0.000). Among the dependent variables, fasting blood glucose (－0.616) and glycated hemoglobin (－0.442) showed median effect sizes, but the effect of fasting blood glucose was not statistically significant. In terms of the study design, non-randomized control trials (NRCTs) (－0.543) was more effective than randomized control trials (RCTs) (0.719). Among, the counseling and self-management program (－3.241) showed a very large effect size. Furthermore, the cognitive-behavioral (－0.828) and self-management (－0.482) programs were also found to have a positive effect on lowering fasting blood glucose. As the importance of diabetes management increases, further studies based on RCT should be actively performed, and differentiated and specialized diabetes intervention plans need to be established.

금융교육의 목표와 방향을 개인의 금융 역량 강화에 두고 이를 위한 실천 전략을 마련하려 면, 먼저 개인의 금융 역량 수준을 파악하고 개선이 필요한 역량의 하위 영역이 무엇인지를 구체적으로 파악하고 있어야 한다. 금융 역량을 지식, 태도, 행위의 3개 하위 영역으로, 내 용별로는 기초, 소득과 소비, 예금과 투자, 부채와 신용, 보험과 연금의 5개 하위 영역으로 구분한 후 각 영역에 같은 비중을 두고 성인의 금융 역량을 측정했다. 금융 지식의 평균 점수는 15개 만점 기준으로 9.38개이며, 남자가 여자보다 높다. 나이가 많아질수록 금융 지식 수준이 높아져 50대부터는 평균이 10개를 넘어선다. 학력과 소득 수준이 높고 투자를 활발히 하는 사람의 금융 지식 수준이 높다. 복리, 물가와 생계비의 관계, 예금자 보호 제도 의 구체적 내용, 보험 관련 핵심 용어에 대한 이해도가 매우 낮다. 금융 태도와 금융 행위 모두 예금과 투자 영역에서 개선의 여지가 가장 많으며, 특히 높은 수익률을 추구하면서도 위험은 감수하려 하지 않으며, 금융 의사결정에 대한 자신감이 부족한 것으로 나타났다. 개 인연금에 가입하지 않은 성인도 많이 있어 노후대비가 취약하다는 문제도 드러났다. 이와 같은 조사 결과를 고려하면, 금융교육의 우선순위를 복리의 의미, 구체적인 예금자 보호 제 도 내용, 대출 상환 기간과 부담 이자 사이의 관계, 대출 시 복리의 적용, 수익성과 안전성 사이의 상충 관계, 예금이나 투자 관련 역량, 개인연금에 대한 접근 등에 둘 필요가 있다.

This study examined the nutrient intake of Korean adults by considering the lunch type, categorized as home meals (HM), eating out (EO), and institutional meals (IM). Data was obtained from the 2019 Korea National Health and Nutrition Examination Survey (KNHANES). Totally, 3,786 adults (1,643 men, and 2,143 women) aged between 19-64 years were included in the study. Subjects with daily energy intake of less than 500 kcal or over 5,000 kcal, and those who skipped lunch, were excluded. The percentage of subjects in the HM, EO, and IM were 31.9, 53.6, and 14.4%, respectively. The daily energy intakes of the HM, EO, and IM groups were determined to be 2,185, 2,360, and 2,339 kcal, respectively, in men, and 1,622, 1,731, and 1,741 kcal, respectively, in women. Among the three groups, men in the EO group had more intake of fat, saturated fat, cholesterol, sodium, and riboflavin, and less dietary fiber, and whereas women consumed more fat and less dietary fiber and potassium. In the IM group, the men consumed more dietary fiber, potassium, and thiamine, whereas consumption of carbohydrate, unsaturated fatty acid, sodium, potassium, and thiamine was more in women. Energy contributions of carbohydrate, protein, and fat were all within the AMDR (acceptable macronutrient distribution ranges) for all lunch types, except for the percent of energy provided from saturated fat in EO (7.4% in men, and 8.2% in women). Our results indicate that the dietary habit of frequently eating out increases the fat intake, thereby resulting in increased health risks for adults. Thus, implementation of a nutritional education program to encourage balanced dietary habits is required to improve the nutritional status of individuals eating out.

This study investigates the relationship between vitamin C intake and obesity prevalence among Korean adults. Based on data of the Korean National Health and Nutrition Examination Survey (2016-2017), a total of 1,356 participants were included in this analysis. Increasing the dietary vitamin C intake resulted in a significantly decreased occurrence of BMI obesity prevalence (p for trend=0.0194) and WC obesity prevalence (p for trend=0.0452). Moreover, increasing the dietary vitamin C intake of Korean adults having a high frequency of eating breakfast resulted in significantly decreased BMI obesity prevalence (p for trend=0.0406) and WC obesity prevalence (p for trend=0.0432). Among the Korean adults who ate out frequently, decreased BMI obesity prevalence was determined with increased intakes of dietary vitamin C (p for trend=0.0193) and total vitamin C (food and dietary supplements) (p for trend=0.0429), whereas significant decrease in WC obesity prevalence was observed with increased dietary vitamin C intake (p for trend=0.0484). Our results provide conclusive evidence that consumption of dietary vitamin C is associated with obesity prevalence in Korean adults, according to their habits of eating breakfast and frequency of eating out.

목적: 본 연구에서는 40세 이상 한국 성인에서 망막전막(황반부) 따른 심혈관계질환과의 위험요인을 알아보고자 하였다. 방법 : 국민건강영양조사 제7기(2016~2018년) 조사대상자의 건강설문조사와 안과 검진을 받은 40세 이상을 대상으로 망막앞막(황반부)과 관련 있는 심혈관계질환 및 나이과 성별, 체질량지수, 사회학적 요인인 월평균 가구 총소득, 교육수준, 현재흡연율, 월간음주율을 보정하여 로지스틱 회귀분석을 수행하였으며 유의수준은 0.050 미 만으로 하였다. 결과 : 40세 이상 망막앞막(황반부) 유병률은 7.94%(527명)로 남자 3.31%(220명), 여자 4.62%(307명)로 나타났다. 나이에 따른 망막앞막(황반부)은 나이가 1살 많아질 때 교차비가(OR) 1.095배로 높아지고(p<0.001), 고혈압 있는 사람이 고혈압 없는 사람에 비해 망막앞막에 대한 교차비(OR)가 1.268배로 유의한 차이가 있었다 (p=0.024). 결론 : 망막앞막(황반부)과 심혈관계질환과의 관계에서 사회학적인 요인을 보정한 후 통계적으로 유의한 관련 성은 나이와 고혈압으로 확인되었지만, 뇌졸중과 심근경색, 협심증은 유의미한 연관성을 확인할 수 없었다. 이는 40세 이상의 성인이고 고혈압이 있는 사람에게 안검사 및 굴절검사를 진행 할 경우, 망막에 관련된 검사를 할 필요가 있을 것으로 예상 하고 추후 다양한 후속 연구가 필요할 것으로 사료된다.

This study was conducted to investigate the intake status of beverages and water in Korean adults using data from the 8th National Health and Nutrition Examination Survey. The ‘total water’ intake was 2,250.6 g for men and 1,871.2 g for women. Men and women consumed an average of 314.9 g of ‘total beverages’, of which ‘coffee’ was the largest at 107.5 g, followed by ‘others’(65.4 g), ‘milk’ (44.8 g), ‘soda’ (44.1 g), ‘teas’ (20.9 g), and ‘fruits and vegetables’ (18.5 g). The intake of ’plain water’ was 1,059.9 g, and the intake of ’water from food’ consumed was 547.3 g. The ‘total water’ intake decreased with increasing age in males and females (p<0.001). Both men and women showed a tendency toward increased ‘total water’ intake as income levels increased. ‘Plain water’ intake accounted for 51.4% of the ‘total water’ intake in males and females. The intake of all nutrients significantly increased from the Q1 group to the Q4 group by quartile ranges of total water intake. The results of this study showed that the intake of healthy water should be considered, and care and educational programs are needed, especially for older people, to ensure adequate water intake.

This study used a food-frequency questionnaire to estimate fruit consumption by sex, age, and type of fruit to analyze the association between fruit type and metabolic factors. Using food-frequency-questionnaire data from 3,091 adults aged 19~64 years (1,184 men and 1,907 women) in the 2016 Korea National Health and Nutrition Examination Survey, this study analyzed weekly fruit consumption and the consumption frequency of strawberry, oriental melon, watermelon, peach, grape, apple, pear, persimmon/ dried persimmon, tangerine, banana, orange, and kiwi by sex and age groups. Apple was the most-consumed fruit (459.45 g/wk), followed by pear (165.80 g/wk), watermelon (124.80 g/wk), and banana (115.32 g/wk). After adjustment for confounding factors, ED: Please give examples. in the women who ate more than the median consumption of apple, the prevalence of hyperglycemia was 27.4% (OR: 0.726, 95% CI: 0.539~0.979) (p=0.0362), and of high triglycerides, 25.7% (OR: 0.743, 95% CI: 0.564~0.978) (p=0.0340). These rates were lower than those of women who ate less than the median consumption of apple. The results of this study suggest that apple consumption helps improve metabolic indicators in Korean adults.

Background: The classification of foot type can be commonly determined by the height of the media longitudinal arch. The normalized arch height (NAH) is defined as the ratio of navicular or instep heights to the foot length or instep length. Objects: This study investigated the relationships among foot characteristics, such as foot length (FL), instep length (IL), navicular height (NH), and instep height (IH), in Korean young adults. Also, the distribution of foot type based on calculated NAH was assessed. Methods: Three-dimensional foot scanning data of young adults aged 20 to 39 years (total: 1,978; 974 male, 1,004 female) were obtained from the Korea Technology Standards Institute, and used for analyses. NAH was calculated as the following: NH/FL, IH/FL, IH/IL, NH/ IL. Spearman’s rank order correlation was used to identify correlations among variables. The Mann–Whitney U-test and chi-square test were used to compare the sex differences in foot characteristics and distribution of foot type. Results: FL and IL showed a very high correlation (r = 0.94). The correlations between FL or IL and IH (r = 0.50–0.57) were greater than those between FL or IL and NH (r = 0.23–0.72). Males had significantly larger values than females (p < 0.001), and the frequency of pes planus was significantly higher in females than in males (χ2 = 50.09, p < 0.001). Based on the IH/IL index, the neutral foot, pes planus and pes cavus distributed by 16%, 78%, and 6% respectively. Conclusion: Our results on foot arch distribution could be used as basic data in clinical or footwear fields, and our data on differences in arch structure according to sex may facilitate understanding of why injury to the lower limbs differs between males and females.

There is only limited evidence for the association between fruit and vegetable consumption and mental health in Korea. This study examined the relationship between fruit and vegetable consumption and mental health according to physical activity among Korean adult women. Based on data of the Korean National Health and Nutrition Examination Survey (2014-2016), a total of 5,332 participants were included in this analysis. With increasing fruits and vegetables consumption, the prevalence of depressive mood was significantly decreased (p for trend=0.0248). The prevalence of stress perception (p for trend=0.0422) and the prevalence of depressive mood (p for trend=0.0300) were decreased with increasing fruit consumption. The prevalence of depressive mood was significantly decreased when fruit and vegetable consumption (p for trend=0.0370) and fruit consumption (p for trend=0.0356) were increased for those Korean women with low intensity of physical activity. For the obesity group (Body mass index 25 kg/m2), the prevalence of depressive mood was decreased with increasing fruit and vegetable consumption (p for trend=0.0111) and increasing fruit consumption (p for trend=0.0165). In conclusion, fruit and vegetable consumption were associated with mental health according to physical activity among Korean adult women. Further prospective studies are warranted to explore the association between fruit and vegetable consumption and mental health among Korean adult women.
