목적: 본 연구는 한국 성인의 흡연 여부, 흡연 제품 유형(궐련, 전자담배, 가열담배), 흡연 기간이 안압(Intraocular pressure, IOP)에 미치는 영향을 평가하고자 하였다. 방법 : 분석은 국민건강영양조사(KNHANES) 2020–2021년 자료를 활용하였으며, 20세 이상 성인 6,821명을 최종 대상으로 하였다. 흡연 상태(비흡연, 현재흡연, 과거흡연), 흡연 제품 유형, 흡연 기간을 주요 독립변수로 설 정하였다. 연령, 성별, 체질량지수(BMI), 혈압, 당뇨병 여부 등 잠재적 교란요인을 보정한 후 복합표본 선형회귀모 형으로 안압과의 연관성을 분석하였다. 결과 : 단변량 분석에서는 현재흡연자의 평균 안압이 비흡연자보다 약간 높았으나, 다변량 보정 후 흡연 상태 (p=0.49), 흡연 제품 유형(p=0.46), 흡연 기간(p=0.14) 모두 안압과 유의한 관련성을 보이지 않았다. 반면, BMI 증가와 연령 감소는 유의하게 높은 안압과 관련되었다. 또한 음주, 신체활동 등 생활습관 변수 역시 안압에 뚜렷한 영향은 나타나지 않았다. 결론 : 흡연 여부, 흡연 제품 유형, 흡연 기간 등 흡연 관련 요인은 한국 성인의 안압과 독립적으로 유의한 연관 성을 보이지 않았다. 흡연이 안압 상승을 유발한다는 기존 가설과 상반되는 결과로, 흡연의 안과적 영향은 시신경 혈류 저하, 산화 스트레스 증가 등 안압 비의존적 경로(IOP-independent pathways)를 통해 나타날 가능성이 크 다. 향후 종단연구를 통한 기전 규명과 신종담배 사용자의 안과적 영향 평가가 필요하다.

This study investigated the role of snack consumption in daily nutrient intake among Korean adults. Data from The Korea National Health and Nutrition Examination Survey (KNHANES) 2023 were analyzed, involving 4,918 adults, consuming 2,118 men (43.1%) and 2,800 women (56.9%). The analysis assessed daily energy intake from snacks and its percentage of total energy, categorized by sex, age, income, and BMI, using multiple regression to explore associations. On average, 18.8% of daily energy intake, with men at 17.3% and women at 20.7%. Women had higher energy contributions for major nutrients. Snack energy contributions were significantly influenced by sex and age, but not by income or BMI. Young adults (ages 19—29) had the highest contribution at 21.1%, while adults aged 50—64 had the lowest at 17.5%. Time-of-day analysis revealed that 22.7% of snack energy was consumed in the evening (18:00—20:59) and 22.6% at night (21:00 onward). The most commonly consumed snacks were coffee (23.8%) and fruit (20.3%). These findings emphasize that snacks are a significant source of energy and nutrients, highlighting the need for sexand age-specific nutritional interventions that consider snack type, timing, and quality.

고령화의 심화로 질병 구조가 만성질환 중심으로 변화하면서, 치매의 전조 단계인 인지기능 저하는 노년기 건강을 설명하는 핵심 지표로 부상 하고 있다. 한편 노인차별은 노인의 건강 전반에 부정적인 영향을 미치 는 사회적 요인으로 제기되어 왔으나, 인지기능에 미치는 영향에 대한 실증적 검증은 상대적으로 제한적이다. 이에 본 연구의 목적은 ‘2023년 노인실태조사’에 응답한 만 65세 이상 노인을 대상으로 노인의 차별경험 과 인지기능의 관계에서 우울의 매개효과를 검증하는 데 있다. 분석 결 과, 첫째, 노인의 차별경험은 우울 수준을 증가시키는 동시에 인지기능 저하에 유의한 영향을 미치는 것으로 나타났다. 둘째, 우울 수준의 증가 는 인지기능 저하와 유의하게 관련되었다. 셋째, 노인의 차별경험과 인지 기능 저하 간의 관계에서 우울 수준은 부분 매개효과를 보였다. 이는 노 인이 경험하는 차별이 우울을 심화시키고, 이러한 우울이 인지기능 저하 로 이어질 수 있음을 의미한다. 즉, 노년기 인지기능 저하를 예방하기 위 해서는 우울에 대한 개입과 함께 노인이 경험하는 차별을 감소시키기 위 한 접근이 병행될 필요가 있다. 본 연구는 이러한 결과를 토대로 후속 연구를 위한 시사점을 제시한다.

목적: 한국 성인을 대상으로 세 가지 측정방법에 따른 평균 동공간거리를 제시하고 측정방식에 따른 차이를 평가하고 자 하였다 방법 : 숙련된 한명의 검사자가 세 가지 방법(PD 미터, PD 자, 자동안굴절력계)을 이용하여 단안 및 양안에서 원거리 동공간거리를 측정하였다. 정치는 평균±표준편차로 나타내었으며, Paired t-test를 이용하여 기기에 따른 측정값 평균의 차이를 비교하였다. Pearson correlation을 이용하여 측정방식 간 상관계수를 구하였으며, 두 기기 로 측정한 값의 일치도는 Bland-Altman plots 분석을 시행하여 95% 일치도 한계(일치도 하한, 일치도 상한)로 나타내었다. 결과 : 평균연령은 21±2.3세 이었으며, 성별은 남자가 47명(49.5%), 여자가 48명(50.5%)이었다. 세 가지 측 정 장비 모두 남자가 여자에 비하여 유의하게 컸다. 연구 대상자의 양안 평균 동공간거리는 PD 미터 62.53±3.22 mm, PD 자 63.16±3.29 mm, 자동안굴절력계 63.37±3.46 mm로 측정되었다. 대응표본 t검정을 이용하여 측정 방법에 따른 차이를 평가한 결과 PD 미터는 PD 자와 평균적으로 –0.64±2.84 mm의 차이를 보였고(p=0.031), 자 동안굴절력계와 평균적으로 -0.84±2.20 mm의 차이를 보였다(p<0.001). PD 자와 자동안굴절력계는 유의한 차이 를 보이지 않았다. 양안에서 95% 일치도 한계는 PD 미터와 PD 자가 –6.21∼4.93 mm, PD 미터와 자동안굴절력 계 –5.16∼3.47 mm, PD 자와 자동굴절력계 –6.49∼6.08 mm였다. 동공간 거리가 3.5 mm 이상 차이가 나는 경 우는 PD 미터와 PD 자가 18명(18.9%), PD 미터와 자동안굴절력계가 14명(14.7%), PD 자와 자동안굴절력계가 20명(21.1%)이었다. 결론 : 세 기기 간의 평균 차이는 모두 1 mm 이내로 임상적으로 유의한 수준의 불편을 유발하지 않는 범위로 판단되었으나 측정 방식에 따라 3.5 mm 이상 차이가 났던 14.7∼21.1%는 안경을 조제·가공하여 만들었을 때 측 정방식에 따른 오차로 인하여 시각적 불편 및 증상을 호소할 가능성이 있다.

This study aimed to assess adults' perceptions and practices regarding sustainable diets and to identify sociodemographic factors influencing these outcomes. A cross-sectional online survey was conducted with 337 adults from February 5 to 21, 2025. Participants' awareness, willingness to engage in education, and practices related to environmental, health, and consideration aspects of sustainable diets were measured using a 5-point scale. The findings revealed low awareness of sustainable diets (1.80) and moderate willingness to participate in educational initiatives (3.18). Practice scores were highest in the health area (3.53), followed by environmental (3.06) and consideration (2.34) aspects. Females demonstrated significantly greater awareness of sustainable diets (2.06 vs. 1.64, p<0.001) and higher practice scores in the environmental (p<0.01), health (p<0.05), and consideration areas (p<0.001). Adults aged 50 to 59 exhibited the highest practice levels across all areas, including environmental (3.52) and health (3.83). One-person households reported lower practice scores compared to larger households in all areas (all p<0.01). Regression analyses indicated that female gender, older age, and larger household size were positively associated with sustainable dietary practices. In conclusion, while adults exhibited low awareness of sustainable diets, there was moderate interest in education. Sustainable diet practices varied significantly based on gender, age, and household size.

This study compared food security and dietary quality, as assessed by the Korean Healthy Eating Index (KHEI), between single-person and multi-person households among Korean adults using data from the Korea National Health and Nutrition Examination Survey (KNHANES). A cross-sectional analysis was conducted using the KNHANES data. The participants were categorized into single-person and multi-person households based on the household composition. Food security was assessed using a validated questionnaire that categorized households into food-secure, mildly food-insecure, and moderateto- severe food-insecure groups. The dietary quality was evaluated using the KHEI, Nutrient Adequacy Ratio (NAR), and Mean Adequacy Ratio (MAR). The final analysis included 13,647 adults aged 19–64 years. Among them, 1,176 (8.6%) were single-person households, while 12,471 (91.4%) were multi-person households. Single-person households showed a significantly higher prevalence of moderate and severe food insecurity than multi-person households (5.7% vs. 1.8%). The KHEI scores were significantly lower in single-person households (57.5±0.6) than in multi-person households (62.5±0.2, P<0.0001). Single-person households showed higher food insecurity and poorer dietary quality than multi-person households. These findings suggest the need for targeted nutritional interventions and policies to address the dietary disparities across different household types in Korea.

비만은 중요한 공중보건 문제로 최근 스트레스 및 부적응적 섭식 행동과 같은 심리적 요인과 연관되고 있다. 본 연구는 스트레스가 체질량지수(BMI)에 미치는 영향에서 폭식 행동이 매개 역할을 하는 지를 한국 성인을 대상으로 검토하였다. 총 272명의 참여자(정상체중 135명, 비만 137명)가 스트레스 및 폭식 행동에 대한 검증된 자기보고 척도에 응답하였다. 독립표본 t-검정 결과, 비만 집단이 정상체중 집단 보다 유의미하게 높은 스트레스 수준과 폭식 행동을 보였다. 부트스트래핑을 활용한 매개 분석에서는 간접 효과만 존재하는 매개 양상이 나타났다. 즉, 지각된 스트레스는 폭식 행동과 유의한 관련을 보였으며, 폭식 행동은 더 높은 BMI와 관련이 있었지만, 스트레스의 총 효과와 직접 효과는 유의하지 않았다. 이 결과는 스트레스가 부적응적 섭식 행동을 통해 체중에 간접적인 영향을 미칠 수 있음을 시사한다. 따라서 스트레 스 관련 비만 개입에서는 폭식 행동의 조절이 핵심 요소가 될 수 있다.

This study compared the dietary perceptions, food labeling behaviors, and purchasing patterns of vegetarians and nonvegetarians. The data from 5,811 adults aged ≥19 years who participated in the 2023 Consumer Behavior Survey for Food were analyzed. The participants were divided into vegetarians and non-vegetarians according to their dietary practices. Vegetarians were further divided into strict, semi, and occasional vegetarians. Non-vegetarians regularly consumed plantand animal-based foods without dietary restrictions. Vegetarians comprised 15.4% of the participants, and health (50.4%) was the primary motivation for adopting a vegetarian lifestyle. Compared to non-vegetarians, vegetarians prioritized their rights and responsibilities as citizens and identified a vegetable-centered diet as the most crucial factor for health. Vegetarians showed greater interest and trust in food labeling than non-vegetarians. Vegetarians selected a wider variety of food and had different purchasing motivations when purchasing eco-friendly foods than non-vegetarians. Vegetarians exhibited higher purchase frequencies across all categories than non-vegetarians and had different reasons for purchasing convenience foods. These findings highlight the diversity of vegetarian dietary motivations and behaviors, emphasizing the need for tailored dietary policies and education.

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 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.

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 was conducted to identify the nutrition literacy levels of Korean adults and the associated influencing factors. A total of 770 adults aged 19–64 years participated in online surveys and individual interviews conducted according to age groups from May to October 2021. The results of the evaluation of the nutrition literacy levels showed that the average correct answer rate among the participants was 78.7%. Nutrition literacy levels were found to be high in females, lower age groups, metropolis residents, those with high monthly incomes, and those with a bachelor’s degree or higher. Multiple regression analysis showed that males, higher age groups, and rural area residents had a negative correlation with nutrition literacy compared with that of females, lower age groups, and metropolis residents. A more positive correlation was observed in those with higher monthly incomes and educational degrees. In the future, experts should monitor whether the nutritional information transmitted through various forms of media is correct or incorrect, and specific measures should be taken to enhance nutrition literacy to promote the health and nutrition management of Korean adults.

The Body Appreciation Scale-2 (BAS-2) measures the extent to which individuals feel, accept, and respond to their own bodies in a positive manner. Given the research need to explore positive body image and its associations with various sociocultural factors and related consequences among individuals with various cultural backgrounds, several studies have established the psychometric properties and factor structures of the BAS-2 in different languages and samples with different characteristics. The current study investigated the psychometric properties and measurement invariance of a Korean version of the BAS-2 in an older Korean adult population (599 older Korean adults with the average age of 70 years). Data were collected using both online and offline (paper-based) survey questionnaires. The results of exploratory factor analyses and confirmatory factor analysis evidenced the unidimensional factor structure and measurement invariance of the Korean BAS-2 among older Korean men and women, after dropping item 1. Scalar invariance was supported across gender, and men and women did not significantly differ in observed mean scores of the Korean BAS-2. The results also supported good convergent validity and criterion validity. Incremental validity was demonstrated by predicting self-esteem over and above measures of age, BMI, subjective financial and health status, body esteem, and ageism. High internal reliability and test-retest reliability over a 2-week period were confirmed. Overall, the results of this study support the reliable use of a Korean BAS-2 to measure positive body image among older Koreans after excluding item 1.

본 연구는 혈중 비타민 E 농도와 대사증후군의 관련성을 살펴보고 비타민 E의 신체에 미치는 영향을 살펴보고자 한다. 분석 자료는 질병관리본부에서 시행한 국민건강영양조사 제7기 3차 (2018년도) 자료를 사용하였으며 본 연구에서는 만 19세 이상 성인은 대상으로 혈중 비타민 E의 농도를 검사한 대상 자 중 남자 944명, 여자 1,080명을 최종 분석하였다. 자료 분석은 일반적 특성에 따른 혈중 비타민 E 농도 차이는 Chi-square와 t- test로, 혈청 비타민 E 농도와 대사증후군 하부요인들 간의 관계는 Pearson 상관 관계로, 혈중 비타민 E 농도와 관련된 대사증후군 지표는 로지스틱 회귀분석을 하였다. 대사증후군의 하부 요인과 혈중 비타민 E의 회귀분석 결과 HDL-cholesterol이 정상군이 과잉군에 비해 높았으며(OR:1.042, CI:1.028-1.056), 중성지방도 정상군에 비해 유의미하게 높았다(OR:1.010, CI:1.009-1.012)(p<0.01). 따 라서 본 연구를 통하여 환자의 연령에 맞는 영양 및 건강프로그램을 개발할 것을 제안한다.

This study aimed to investigate the need for dietary education and programs for young Koreans belonging to singleperson households in the metropolitan area. A total of 500 young adults aged 19-34 participated in the study through an online survey. Participants responded to questions on general characteristics, dietary problems, and the need for dietary education and programs. The subjects were divided into three groups as follows: Undergraduate students, employed workers, and others. Among the subjects from single-person households, 20.2, 67, and 12.8% were undergraduate students, employed workers, and others, respectively. When asked for their estimation of an appropriate self-pay when participating in a cooking class, 39.8% of total subjects responded ‘5,000-10,000 won’. The most preferred program for young adults in single-person households was the ‘support food package’. For the preferred method of dietary education, undergraduate students showed a greater preference for classes ‘at campuses’. However, employed workers and others had a higher preference for ‘non-face-to-face online classes’. Undergraduate students tended to generally have a higher preference for dietary education and support programs compared to employed workers and others. This study provides data that will be useful for establishing healthy dietary policies and education programs for young single-person households in Korea.

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.
