In the past gut microbiome has been the main focus of microbiome research. Studies about the microbiome inside oral cavities and other organs are underway. Studies about the relationship between noninfectious diseases and periodontal diseases, and the negative effects of harmful oral microbes on systemic health have been published in the recent past. A lot of attention is being paid towards fostering a healthy oral microbial ecosystem. This study aimed to understand the roles and effects of the microbiome inside the human body can potentially help cure various diseases including inflammatory bowel diseases with no known cure such as Crohn's disease, atopic dermatitis, obesity, cancer, diabetes, brain diseases and oral diseases. The present study examined technological trends in the correlation between the human microbiome and diseases in the human body, interactions between the human body's immunity, the metabolic system, and the microbiome, and research trends in other countries. While it has been proven that human microbiome is closely correlated with human diseases, most studies are still in the early stage of trying to compare the composition of microbiomes between health and patient groups. Since the oral environment is a dynamic environment that changes due to not only food intake but also other external factors such as lifestyle, hygiene, and drug intake, it is necessary to continue in-depth research on the microbiome composition characteristics to understand the complex functions of oral microorganisms. Analyzing the oral microbiome using computational technology may aid in disease diagnosis and prevention.

OBJECTIVES: This study investigated physical activity (PA) participation based on demographic, physical, and psychological variables in Korean adults.METHODS: Participants were divided into four groups (combined, aerobic only, resistance only, and neither) based on meeting the PA guidelines using moderate and vigorous PA time and resistance exercise frequency from the Korea National Health and Nutrition Examination Survey 2017. The association between meeting the PA guidelines and demographic, medical, fitness, lifestyle, and psychological variables were analyzed using complex samples crosstabs and a general linear model.RESULTS: Of the 5,820 Korean adults, 66.0% did not meet any of the guidelines. Among demographic factors, sex, age, marital status, income, education level, occupation, and employment status were associated with meeting the PA guidelines. Chronic disease prevalence, weight, waist circumference, body mass index, diastolic blood pressure, glucose, high-density lipoprotein and triglyceride levels, hand-grip strength, resting heart rate, and family history of chronic disease in the medical and fitness variables; frequency of drinking and eating breakfast, total calorie, water, protein, and fat intake in the lifestyle variables; and perceived stress, depression, suicidal thoughts, and quality of life in the psychological variables were associated with meeting PA guidelines.CONCLUSIONS: Most Korean adults participate in insufficient PA. Moreover, individuals who are socially underprivileged, have low-income or poor physical and mental health conditions participated in relatively less PA. Our findings suggest that government and individual efforts are required to increase PA and resolve health inequality in Korean adults.

Mindfulness training is growing in popularity as an adjunctive intervention in disordered eating and weight loss. Lifestyle modification, pharmacologic treatment, and surgical intervention have been widely used for weight reduction in obese persons, but these modifications are sometimes insufficient. In particular, stress-induced eating and binge-eating disorder have been frequently associated with increased risk of regaining weight. Initial research suggests that mindfulness training may be an effective intervention for binge eating. In this article, we reviewed 19 studies that investigated mindfulness training as an intervention for weight change and/or emotional eating. Results suggest that mindfulness training effectively decreases emotional eating in persons with good adherence to the training; evidence for its effect on weight reduction, however, is mixed. Further large-scale studies are warranted to explore the effectiveness of mindfulness training on long-term weight loss and emotional eating in persons with obesity.

BACKGROUND: Korea's population is aging rapidly. Aged people who lead a solitary life are in a state of social isolation and face a greater risk of lower quality of life. The purpose of this study was to analyze the health behaviors and lifestyle patterns of aged people who lead a solitary life in Korea.METHODS: We analyzed 4,471 subjects (1,933 men and 2,538 women)-aged people aged 65 or above-based on data from the Korea National Health and Nutrition Examination Survey VI (2013–2015). The odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed using multivariate logistic regression analysis adjusted with age, household income level, occupational status, and geographical region.RESULTS: Socioeconomic status was lower in aged people who lead a solitary life than in those living with family. The ORs for frequent eating out alone (OR=2.93; 95% CI 1.83–4.38), daily eating out alone (OR=2.40; 95% CI 1.25–4.60), smoking (OR=1.57; 95% CI 1.06–2.32), feeling sick or uncomfortable (OR=1.59; 95% CI 1.08–2.36), feeling depressed (OR=4.10; 95% CI 2.53–6.65), and suicide ideation (OR=2.06; 95% CI 1.21–3.51) were significantly higher in male subjects who lead a solitary life. The ORs for frequent eating out alone (OR=1.57; 95% CI 1.10–2.24) and inadequate sleep duration (OR=1.29; 95% CI 1.03–1.61) were significantly higher in female subjects who lead a solitary life.CONCLUSION: Aged people who lead a solitary life exhibited unhealthy behaviors and poor mental health. The elderly men who lead a solitary life faced higher risk of poor health than the women. Integrated management of lifestyle behaviors is required to improve the quality of health in aged people who lead a solitary life.

From the early stage of diabetes diagnosis, it may necessary to modify lifestyle including nutrition and physical activity. Self-management instruction and support can result in healthy eating habits for effective blood sugar management. Clinical nutritionists must conduct accurate nutritional assessments for successful dietary change and patient health. They must also diagnose and prioritize the nutritional problems to be addressed. Through medical nutrition therapy, nutritionists must instruct and encourage patient self-management skills based on evidence-based nutritional guidelines and education about viable strategies. For this purpose, educators should strive continuously to acquire knowledge and professional training.

Diet-related behavioral modification for healthy eating and lifestyle is required to improve childhood obesity. The present study aimed to develop customized nutritional intervention protocol and education program to find barriers to adhere healthy diet and lifestyle for moderate to severe obese children and adolescents and their families. Theoretical framework approaches can be used to change behavior and achieve goals. Previous studies that described the relationship between behavioral modification and nutrition education theory were reviewed. The social cognitive theory and transtheoretical model were employed with behavioral changes to target a healthful diet and lifestyle. The nutrition care process (NCP) model was adopted to customize nutrition care for the participants. Customized nutritional intervention protocol was developed following as the four steps of the NCP. Firstly, nutrition status of the participants was assessed by the nutrition expert. Nutrition problems were described as “inadequate energy intake,” “overweight/obesity,” or “food and nutrition-related knowledge deficit.” All nutrition sessions were designed for nutrition intervention to give nutritional knowledge and a practical mission in real life for individual goal setting and self-control. Meal planning, portion control, healthy snack selection and cooking with fruits and vegetables were consisted of five components of the nutrition education session. During each session, the participants and their families were interviewed by a nutrition expert for monitoring and evaluating diet-related goal setting and achievement. A theoretical and evidence-based nutritional intervention was developed for the secondary to tertiary prevention of childhood obesity. This nutrition intervention protocol and program might be helpful for the further research on childhood obesity. TRIAL REGISTRATION: Clinical Research Information Service Identifier: KCT0002111

The aim of this study was to construct and test a structural equation model for the risk factors of metabolic syndrome in Korean adults. The structural equation model hypothesizes that eating alone and feeling depressed is a risk factor for metabolic syndrome. The data of this study were obtained from the Sixth Korea National Health and Nutrition Examination Survey which was cross-sectional data from the representative national survey. A total of 4,013 subjects replied to the survey item of lifestyle and completed the physical examinations among adults aged 19 years or older in South Korea was in 2015. The structural model in this study was composed of four latent variables: eating alone, depression, negative health behavior, and metabolic syndrome. Two variables, the rate of eating alone and depression, were exogenous variables. Negative health behavior was both a mediating variable and endogenous variable, and metabolic syndrome was the final endogenous variable. The data were analyzed using the Maximum Likelihood method and bootstrapping. The structural model was appropriate for the data based on the model fit indices. The results of this study can be summarized as follows: Eating alone is a direct risk factor of metabolic syndrome in Korean women. Depression can mediate metabolic syndrome through negative health behaviors. Negative health behavior had a direct impact on metabolic syndrome in both men and women. This study may be a guideline for interventions and strategies to reduce the incidence of metabolic syndrome in Korean adults.

This study evaluated the nutrient intake with increasing coffee consumption for 403 adults aged over 30 years in Korea. The 403 subjects were national health screening examinees, who visited Sahmyook Seoul Hospital's Comprehensive Check-up Center between 2017.11.01 and 2018.12.18. The subjects were asked to answer questionnaires covering a 24-hour recall fluid and dietary intake before the health examination. The research ethics council of Sahmyook University (2-7001793-AB-N-012019036HR) approved this study. Coffee consumption exceeding two servings daily was more likely in males, in those aged between 30 and 40 years, and in the smoking, drinking, non-exercise, non-breakfast groups compared to each counterpart. The correlation between the coffee consumption frequency and current nutrient density showed negative correlations in most micronutrients. The mean nutrient density decreased gradually with increasing coffee consumption (<1 serving daily, ≤1~2 servings daily, >2 servings daily) in the ANOVA analysis. Therefore, the progressive adverse health effects of excessive coffee consumption needs to be researched further, and a daily total caffeine limit should be suggested in education of the nation levels.

BACKGROUND: Few studies have examined the association of workhours and shift work (referred to here as "time-related work factors") with dietary behaviors. We aimed to investigate this association, as well as the dietary behaviors among individuals with occupations characterized by time-related work factors. METHODS: A cross-sectional study was performed using data from the Japan Environment and Children's Study. The study included 39,315 working men. Dietary behaviors (i.e., skipping breakfast, eating out, eating instant food, overeating, and eating fast) were assessed with a self-reported information from the Food Frequency Questionnaire. Logistic regression analysis was conducted to examine the associations of time-related work factors with dietary behaviors and dietary behavior tendencies among those in occupations characterized by long workhours and/or shift work. RESULTS: Long workhours were associated with high frequencies of skipping breakfast, eating out, eating instant food, overeating, and eating fast. The frequency of having shift work was associated with high frequencies of skipping breakfast, eating out, and eating instant food. Several occupations involving long workhours and/or shift work showed specific dietary behaviors; in some occupations, the level of significance changed after adjusting for time-related work factors in addition to other potential confounding factors. CONCLUSIONS Time-related work factors may help explain workers' dietary behaviors. Long workhours and shift work may lead to poor dietary behaviors. Other factors influenced by occupation itself, such as food environment, may also influence workers' dietary behaviors. Workhours and/or shift work, and these other work factors, should be given attention in workplace health promotion.

PURPOSE: Koreans' internet and smartphone usage hours are steadily increasing and the dependence of young people on smartphones is causing social problems. Therefore, this study was conducted to examine health and dietary habits, as well as hair mineral contents according to the level of dependence of smartphone use among adolescents to clarify the interrelation of smartphone dependence, lifestyle, dietary behavior, and mineral nutrition status. METHODS: A total of 80 smartphone-addicted adolescents participated in this study and were divided into three groups (general, potential and danger group) according to smartphone dependence. The subjects' lifestyles and dietary behaviors were then surveyed, and hair mineral contents were analyzed. RESULTS: Higher smartphone dependence was associated with lower average weekly sleeping time and later first smoking age. In the danger group, the rate of eating fast and the rate of snacking twice a day was also relatively high. Parents (45.0%) and mobile (30.0%) were the factors having the greatest influence on an individual's dietary behavior. In the hair mineral analysis, all subjects had lower selenium concentrations and higher lead concentrations than normal. In addition, the levels of aluminum in the danger group were higher than in the normal range and the highest among the three groups. CONCLUSIONS: It is necessary to guide adolescents to use smartphones correctly and manage dietary habits. In addition, careful attention is needed the mineral nutritional status of smartphone-addicted adolescents.
