Object: Physical inactivity of Korean is substantial public health problem and American physical activity paradigm have effected many influences to Korea. So we reviewed American physical activity paradigm for Korean implication. Methods: Knowledge base has been searched including six American national physical activity guidelines. four plans, two monitring system and three interventions. Results: American physical activity paradigm has been changed substantially. Physical activity part in Healthy People were improved. National physical activity plan were made and improved. Monitoring system like physical activity report card has usefull. Some community-wide campaign showed effect. Most of them have good implication to Korea. Conclusions: American policy have good implication for Korea. Especially Korearn national physical activity plan is needed on good governance. Report card and community wide campaign may good example to consider in Korea.

Purpose: The purpose of this study examined the changes in participants' walking practice and mental health after conducting a walking education program. Method: This study is an quasi-experimental study and examined the changes in participants before and after the 8-week walking program. Subjects were recruited through the health center of the village under the public health center, and their walking practice and mental health were investigated before and after to check the changes in the participants. Of the total 219 participants, 181 responded to both the before-and-after surveys. The program was conducted from May to June in 2024, and the comparison was made on walking practices, elements for walking practices (attitude, subjective norms, perceived behavioral control, intention of walking, participation of walking), stress, feeling depression and loneliness in daily life. In statistical analysis, descriptive statistics, X2, paired t-test were performed using SPSS 23.0. Result: The number of walking practice days increased, and attitude to walking, subjunctive norms, and participation to walking were changed positively. Regarding to mental health, among the loneliness questionnaire, only one item which was ‘there are people who can help me with everyday matters’ were changed positively. Conclusion: Through this study, it was confirmed that even a short period of walking education can increase the walking practice days, but mental health in older people was difficult to change through exercise in a short period of time.

Objectives: This study was conducted to analyze the effect of nutrition label use on blood glucose control in adult diabetic patients in Korea and to present basic data for proper blood glucose management in diabetic patients. Methods: Multiple logistic regression analysis was conducted with 1,422 subjects to investigate the effect of nutrition label use on blood glucose control in adult diabetic patients using data from the 8th period (2019-2021) of the National Health and Nutrition Survey, and SPSS 27.0 was used. Results: As a result of performing logistic regression analysis after adjusting for demographic characteristics, health behavior, and health outcome factors, the probability of blood glucose control was 37% lower in diabetic patients who did not use nutrition label than in diabetic patients who did. And in diabetic patients who did not know nutrition label, the probability of blood glucose control was 34% lower. In addition, compared to the diabetes treated group, the probability of blood glucose control in the non-treated group was 3.63 times higher. The probability of blood glucose control in normal and underweight subjects was 1.39 times higher than those suffering from obesity. In the case of hypertension, the probability of blood glucose control in normal subjects was 35% lower than those of patients with disease. Conclusions: It was confirmed that nutrition label use can affect blood glucose control, and it is necessary to actively control blood glucose through appropriate dietary intake using nutrition label to manage diabetes.

Objectives: This study systematically evaluated the effectiveness of school-based interventions in reducing internet gaming disorder (IGD) severity among adolescents. Methods: A systematic review and meta-analysis were conducted, searching international databases (MEDLINE, Embase, PsycINFO, Cochrane CENTRAL, CINAHL), and Korean databases (DBpia, KCI, RISS, KIST) for studies published before May 2024. Nine quasi-experimental studies with 764 participants were included. Effect sizes were calculated using a random-effects model (Hedges’s g) with 95% confidence intervals (CIs) and heterogeneity statistics (I2). Subgroup analyses examined intervention type, duration, session, and participant characteristics. Risk of bias was assessed using the ROBINS-I tool. Results: Meta-analysis revealed a significant reduction in IGD severity (Hedges’s g=-1.171, 95% CI [-1.673, -0.669]) with high heterogeneity (I2=87.48%). Educational interventions were more effective than physical activity-based programs (Hedges’s g=-1.289 vs. -0.775). Interventions led by psychologists showed greater effectiveness than those led by teachers (Hedges’s g=-1.581 vs. -0.884). Short-term interventions (<3 months) with at least 10 sessions and durations of ≥1 hour demonstrated the highest efficacy. The higher the boy-to-girl ratio and primary school students responded more positively than other groups. Heterogeneity was attributed to variability in study designs and participants demographics. Conclusion: School-based interventions significantly reduce IGD severity among adolescents, particularly when tailored to developmental and demographic needs. Teacher-led and psychologist-led interventions were the most effective, highlighting the importance of design and delivery. Future studies should adopt standardized evaluation tools, include randomized controlled trials, and implement long-term follow-ups to strengthen evidence. Additionally, incorporating family support and tailored IGD strategies may enhance interventions successful in school settings. This study systematically evaluated the effectiveness of school-based interventions in reducing internet gaming disorder (IGD) severity among adolescents.

Objectives: We conducted a study on the consumption of caffeinated drinks, which have been very popular in University students in Korea, and a comparative study on the consumption pre- and post-COVID-19 of caffeinated energy drinks. Methods: The subjects of the study were college students attending universities located in the metropolitan area in Korea, and the analysis was conducted using data from a total of 252 people. In addition, the response data of 137 people in 2018 and 115 people in 2022 were used for the analysis. Results: We investigated the amount of caffeinated drinks consumed, the reason for consumption, changes in the amount consumed during special periods, the influence of caffeinated beverages, whether they experienced side effects from caffeine and the duration of side effects, whether they interfered with daily life, and their intention to consume caffeinated energy drinks in the future, and the results were presented. Conclusion: In the difference analysis by demographic and socioeconomic items as a result of the comparison before and after COVID-19, it was analyzed that most items showed statistically significant differences at the significance level of p<.05, and the results were presented. Additionally, statistically significant differences were also found in several questions depending on gender and research period.

Purpose: This study investigated the association between patterns of alcohol consumption and levels of mental health, as well as the relationship between these patterns and depression. Methods: Data from three years ((2016, 2018, 2020) of the Korea National Health and Nutrition Examination Survey (KNHANES) were analyzed. After excluding missing values, 16,772 respondents were included in the study: 1,796 lifetime abstainer, 2,882 former drinker, 3,132 current infrequent drinker, 6,831 current light drinker, 945 current moderate drinker, 1,186 current heavy drinker. All data were analyzed with weighting, and hierarchical logistic regression analysis was conducted to identify the association between alcohol consumption pattern and depression. Statistical analysis was performed using SAS version 9.4. Results: The most prevalent alcohol consumption pattern among Korean adults was identified as current light drinker. However, participants who have experienced depression were found to constitute the largest proportion within the current heavy drinker. Disparities in the association with depression were observed based on patterns of alcohol consumption, drinking frequency, drinking amount, and frequency of binge drinking. Among the patterns of alcohol consumption, it was found that current moderate drinker and current heavy drinker were respectively 1.845 times (95% CI 1.173-2.902) and 2.167 times (95% CI 1.421- 3.304) more likely to experience depression compared to lifetime abstainers. In case of the drinking frequency, it showed a U-shaped association with depression, while the drinking amount and frequency of binge drinking exhibited a linear association with depression. Conclusions: While moderate alcohol consumption may positively impact social relationships, the national losses from problematic drinking and alcohol misuse far outweigh any potential societal benefits. Given the significant likelihood that current light drinkers may transition into moderate or heavy drinkers, it is imperative to establish comprehensive abstinence policies that consider each drinking patterns.

Objectives: Unemployment and job loss are associated with an increased risk of problem drinking, which poses significant health risks. This study aims to assess the prevalence of problem drinking among and analyze its influencing factors using the ‘International Center for Alcohol Policies (ICAP) Determinants of Drinking Framework.’ Methods: A survey was conducted among 1,074 unemployed South Korean adults who visited a regional Center for Employment and Welfare. Problem drinking was assessed using the Alcohol Use Disorder Identification Test (AUDIT), with scores of 8 or higher classified as indicative of problem drinking. The data was analyzed using a hierarchical logistic regression model. Results: The average AUDIT score among participants was 6.87, with 38.2% identified as problem drinkers. Hierarchical logistic regression analysis revealed that younger age, higher levels of depression and embitterment, male gender, and absence of religious affiliation were significant factors associated with an increased risk of problem drinking. Conclusions: This study underscores the necessity of addressing problem drinking among the unemployed population through the implementation of targeted interventions.
