Background: To promote and maintain oral health among adults, the relationship between oral health and obesity was examined, and the effects of oral health on obesity were investigated. Methods: A total of 4,270 Korean adults aged ≥20 years were selected as study subjects using raw data from the first year (2019) of the eighth period of the Korea National Health and Nutrition Examination Survey (KNHANES). Complex sample Rao-Scott chi-square test and complex sample logistic regression analysis were performed using PASW Statistics ver. 18.0. Results: The prevalence of abdominal obesity was 1.3 times higher subjects with poor oral health than in those with good perceived oral health and 1.3 times higher in subjects who did not receive dental checkups compared to those that did. The frequency of brushing of teeth was 1.2 times higher for subjects who reported brushing 2~3 times per day compared to those who reported brushing four or more times per day. The risk of being overweight was 1.3 times higher in subjects with one or more dental implants than in those with none. Conclusion: To build an integrated health program, it is thought that a preventive approach through self and expert oral health care, considering the age-specific characteristics of adults, is necessary for the intervention process used to build customized obesity prevention projects at the national level.

Objectives: This study investigated dietary and lifestyle factors associated with the weight status among Korean adolescents in multicultural families. Methods: This cross-sectional study analyzed 1,751 multicultural families' adolescents who participated in the 2017-2018 Korea Youth Risk Behavior Surveys. Information on dietary and lifestyle factors was self-reported using a web-based questionnaire and this information included breakfast and foods consumption, perceived health status, alcohol drinking, smoking, physical activity, and weight control efforts. Body mass index (BMI) was calculated based on the self-reported height and body weight (kg/㎡). Weight status was assessed according to the 2017 Korean National Growth Chart: underweight (weight-for-age <5^th percentiles), overweight (85^th≤ BMI-for-age <95^th percentiles), and obese (BMI-for-age ≥95^th percentiles). Multiple logistic regression analysis was performed to examine the dietary and lifestyle factors associated with weight status after adjustment for covariates. Results: Among Korean adolescents from multicultural families, the prevalence of overweight/obesity was 20.9%, whereas about 7% of adolescents were underweight. The weight status did not show differences according to gender, school level, area of residence, and household income. Compared to adolescents who did not have breakfast during the previous week, those who had breakfast 3-4 days/week and ≥5 days/week had a 42% (p=0.021) and a 37% (p=0.009) lower prevalence of overweight/obesity, respectively. The adolescents who frequently consumed carbonated soft drinks (≥5 times/week) showed an odds ratio (OR) of 1.69 (95% CI=1.01-2.83) for overweight/obesity relative to those adolescents who did not consume carbonated soft drinks. The OR of being underweight for adolescents who ate fast food ≥3 times/week was 1.97 (95% CI=1.04-3.71) compared to those adolescents who had not eaten fast food during the previous week. Conclusions: Dietary and lifestyle factors were associated with overweight/obesity as well as underweight among Korean adolescents in multicultural families. Our findings could be used to design and provide nutrition interventions for this specific population.

Objectives: This study examined the association between the dietary behavior and weight status of preschool children and their mothers in Daejeon, Korea. Methods: A total of 301 mother-preschool children (aged 3~6 years) dyads were included in this study. The dietary behavior of children and their mothers was assessed using the Nutrition Quotient (NQ) questionnaire for preschoolers and adults, respectively. The NQ questionnaires were completed by the mothers. The overweight/obesity status of children and their mothers was determined using data on height and body weight reported by the mothers. Multiple logistic regression was performed to examine the relationship between the dietary behavior and weight status of children and their mothers. Results: The mean NQ score was 58.9 ± 9.7 in children and 55.6 ± 9.2 in mothers. The NQ score was higher in boys than girls but did not vary by age. The prevalence of overweight/obesity was 27.5% in children and 46.5% in mothers. The physical activity level of mothers and their NQ scores were positively associated with the NQ scores of the children. After adjustment for covariates, the mothers in the highest tertile of NQ scores showed a lower odds ratio (OR) for the unhealthy dietary behavior of children (OR = 0.24, 95% CI = 0.11~0.53, P < 0.001) compared to those in the lowest tertile. The obese mothers showed a higher OR for children's overweight/obesity (OR = 3.38, 95% CI = 1.68~6.80, P = 0.001) compared to normal weight mothers. Conclusions: The dietary behavior and weight status of young children and their mothers were closely linked. Nutrition education programs targeting mothers are necessary for improving maternal and child nutrition. Specifically, these programs need to be tailored to the socioeconomic characteristics or weight status of mothers.

This study was conducted to investigate the body weight control, attitudes, lifestyles and dietary habits according to the obesity index of elementary school students. This study utilized questionnaires and body composition measurements collected with a bio- electrical impedance analyzer(Inbody 4.0). Specifically, differences between the underweight group, normal group, and overweight group were tested by a $x^2$-test or ANOVA and Duncan's multiple range test. The subjects consisted of 571 elementary school students residing in Chonbuk Province. The average age, height, weight, and BMI of the male subjects was 11.5 years, 150.0 cm, 45.2 kg and $20.0\;kg/m^2$, respectively. The average age, height, weight, and BMI of the female subjects was 11.5 years, 152.2 cm, 46.1 kg and $19.8\;kg/m^2$, respectively. Twenty percent of the subjects were in the underweight group, 52.2% were in the normal weight group, and 27.8% were in the overweight group according to the Korean Pediatrics Society standards. A total of 50.2% of the subjects were dissatisfied with their body weight, while 36.8% of underweight, 42.3% of normal weight, and 81.1% of overweight subjects were dissatisfied with their weight. Fifty two percent of the subjects had attempted to reduce their body weight, including 50% of the normal weight group. The main reason for wanting to reduce body weight was to maintain health. The percentage of subjects who had received body weight control education was 41.3%, but 77.6% of the subjects thought it was necessary. Poor time management, lack of physical activity, portion size of meals, unbalanced diet, frequent consumption of convenience foods, and frequent snacking all affected the obesity index. Overall, the results of this study indicate that it is necessary to develop weight control programs for all elementary school students who are underweight, normal weight, and overweight.

Obesity and overweight pose a significant public health problem, as they are associated with an elevated risk of metabolic syndrome (MetS). Several studies have shown that diet quality is associated with the development of MetS risk factors. Analyzing dietary patterns may be more helpful in determining the relationship between eating habits and chronic diseases compared to focusing on single foods or nutrients. In this study, our objective was to evaluate the association of food quality score (FQS) with risk factors for MetS in individuals with obesity and overweight. The participants in this cross-sectional study were 340 adults with overweight and obesity. Participants' food intake was measured using a Food Frequency Questionnaire, then the FQS was calculated. A fasting blood sample assessed serum glucose, triglycerides, total cholesterol (TC), high-density lipoprotein cholesterol, and serum insulin levels. Fat-free mass, height, basal metabolic rate, socio-economic score, and waist-to-hip ratio significantly differed among FQS tertiles. TC, systolic and diastolic blood pressure, and fasting blood glucose were significantly lower in the highest tertile of FQS. After multivariable adjustment, our results showed that individuals in the third tertile of FQS had reduced risk of higher levels of TC (odds ratio [OR], 0.982; 95% confidence interval [CI], 0.970-0.984) and higher levels of low-density lipoprotein cholesterol (OR, 0.974; 95% CI, 0.974-0.999). Our findings demonstrate an inverse relationship between diet quality, as measured by FQS, and MetS risk factors. However, further experimental and longitudinal investigations are warranted to elucidate the causal nature of this association.

This study aimed to analyze the effect of flexi-bar exercise on in body composition and trunk muscle strength of female college students who are either overweight or obesity. The subjects were female college students divided into experimental group(N=15) and control group(N=15). The experimental group performed a flexi-bar exercise for of 30 minute sessions three days per week for five weeks, and the differences in body composition and trunk muscle strength before and after the experiment and between experimental group and control group were analyzed. The study results showed that the experimental group had a statistically significant improvement in the body fat mass and body fat percentage, body muscle mass, both arm muscle mass, trunk muscle mass, basal metabolic rate(p<.05). Changes in trunk muscle strength showed that the experimental group had statistically significant increased in changes in trunk muscle strength(p<.01). The study verified that flexi-bar exercise can be effective for improving the body composition and trunk muscle strength of overweight and obesity female college students.

The objective of this study was to investigate the associations between the prevalence of overweight and obesity and the degree of adherence to the Korean Dietary Action Guides for Children (KDAGC). In a cross-sectional study based on a child care center-based survey in Seoul, Korea, we collected parental-reported questionnaires (n = 2,038) on children's weight and height, frequency of fruit and vegetable consumption, and the quality of dietary and activity behaviors based on the 2009 KDAGC Adherence Index (KDAGCAI) which was developed as a composite measure of adherence to the KDAGC. Overweight and obesity were determined according to age- and sex-specific BMI percentile from the 2007 Korean national growth chart. Associations were assessed with generalized linear models and polytomous logistic regression models. Approximately 17.6% of Korean preschool children were classified as overweight or obese. Obese preschoolers had lower adherence to the KDAGCAI compared to those with lean/normal weight. Preschoolers with a high quality of dietary and activity behaviors had a 51% decreased odds ratio (OR) of being obese (highest vs. lowest tertile of KDAGCAI-score, 95% CI 0.31, 0.78; P = 0.001); the associations were more pronounced among those who were older (P = 0.048) and lived in lower income households (P = 0.014). A greater frequency of vegetable consumption, but not fruit, was associated with a borderline significant reduction in the prevalence of obesity. Our findings support the association between obesity prevention and high compliance with the Korean national dietary and activity guideline among preschool children.

For obesity management requires accurate measurement of abdominal fat. The purpose of this study was to find out the correlation between abdominal fat and lipid measured with BIA and CT. Secondly, This study investigate for usefulness of abdominal fat measured by BIA and CT as an obesity index. As a result, TG showed higher value in the overweight obese group than normal group but HDL showed lower value in the overweight obese group than normal group. TG and HDL appeared significantly relationship with by BIA and CT in the normal group. However, in the overweight obese group TG showed significantly relationship with the BIA. According to multiple regression analysis on BMF and TAF was affected by HDL in the normal group. And BMF, %BF was affected by TG in overweight obese group. In conclusion, abdominal fat showed significant correlation with lipid. Abdominal fat measured by BIA and CT to assess obesity index is considered as a useful way to evaluate.

Along with the increasing interests of modem-day society toward topics of health and beauty, various studies are being actively conducted on the effects of diet for obesity prevention, and separate from aspects of disease prevention and health promotion. This study aimed to examine individual perceptions of obesity by age, and to prepare basic data for implementing an age-based weight control system, by comparing attitudes toward weight control. The research and analysis were conducted using questionnaires, provided to high school students(teenagers, 189 students), college students(20 or older, 116 students), and adults(30 or over, 88 adults) living in Daegu City. In terms of the respondents' perceptions of obesity, among those who described themselves as overweight, only about 10% were actually proven to be overweight. Also, significantly more female students than male students perceived themselves as overweight, despite the fact that they were in a normal weight range(p<0.007). There was no significant difference in the cause of obesity by gender, but it was found to be attributed to a lack of exercise for teenagers, and poor eating habits for those in their twenties and thirties. Concerning the intention to participate in a weight management class, the female teenagers showed significantly more interest than the male teenagers(p<0.017). Also, with regard to the respondents' attitudes toward weight control, the teenage females showed significantly higher interest in weight control than the teenage males p<0.003 and those in their twenties p<0.001. Moreover, regarding the period in which the respondents became most interested in weight, the teenage male students were most interested in weight during their middle school years and teenage females became most interested during their high school years. Therefore, the information from this study leads us to propose there is a need to correct the suggested reckless dieting that is occurring within an appearance-based society, as well as a need to establish a systematic weight control system, along with gathering subsequent basic data.

Objectives: This retrospective study attempted to determine whether the treatment effect improves as the longer the medication for obese patients, also, analyzed whether the long medication increases the burden on liver function. Methods: The subjects were 278 overweight and obese female patients who took the herbal medicine Jibangsayak (JBSY) for more than 15 days. The correlation between the duration of medication and the treatment effect was confirmed, and the correlation with the safety was also analyzed. Results: JBSY significantly reduced all obesity-related measures after treatment. All these valuables before treatment were not factors in determining the duration of medication. As the duration increased, the body mass index (BMI) improvement decreased and lean body and muscle mass increased. As the duration was closer to 60 days, BMI improvement increased, and in more than 90 days group, the BMI and body fat percentage improvement stagnated as the duration longer. Aspartate aminotransferase (AST), alanine aminotransferase, and gamma-glutamyl transferase decreased after treatment. Additionally, AST decreased as the duration increased. Conclusions: This result suggests that not only the high obesity-related measures at first visit not lengthen the duration of JBSY medication. And liver function levels did not worsen as the duration increased. This result is different from the general perception that the longer the duration of medication, the greater the burden on patient's drug metabolism. However, the fact that other factors that could affect liver function could not be excluded and that kidney function evaluation should have been performed simultaneously are limitations of this study and require more detailed research in the future.
