This study was a secondary data analysis study to determine the relationship between mental health counseling and the current prevalence of depression in the Korean adult population. Data were extracted from raw data of the 7th 3rd year (2018) of the National Health and Nutrition Examination Survey (NHANES) conducted by the Korea Centers for Disease Control and Prevention. The subjects of this study were 6,238 adults aged 19 years or older who participated in the NHANES conducted from January to December 2018. The collected data were analyzed by frequency analysis and logistic regression analysis of the complex sample by the SPSS/WIN 27.0 version program. The mental health counseling statistically significant associated with variables such as sex, marital status, economic activities, and family income level, respectively (p<0.05). The prevalence of depression statistically significant associated with age group (p<0.0001). The odds-ratio of current prevalence of depression was 5.09 times (OR, 5.085; p<0.0001) lower in subjects who had undergone mental health counseling for the past year compared to subjects who did not. These findings could be useful as evidence-based data for the prevention and management of depression by predicting the vulnerable factors for mental health in the Korean adult population.

This study examined the effects of eating with others on depressive symptoms among the community-dwelling older adults by family arrangement, using the Korea National Health and Nutrition Examination Survey 7th (2016). A total of 1,233 older adults aged over 65 was included in this analysis. Eating status (alone / with others) and family arrangement (living alone / living with family) were dichotomized based on the original questionnaire. Among 955 older adults who live with family members, 855 persons (89.5%) eat together and 100 persons (10.5%) eat alone. Among 278 older adults who live alone, 86 persons (30.9%) eat together and 69 persons (69.1%) eat alone. Regression analysis controlling for demographic and health related factors, eating with others was significantly related to lower levels of depressive symptoms in the group of older adults who live with family members (β = -1.663, p <.001), while there is no statistical significance (β = -0.856, p = .148) in the counterpart. Therefore, various types of community-based programs need to be developed to encourage older adults to eat with other in their ordinary lives. It is also recommended that the community has to offer consistent care and support for the elderly particularly who live alone.

Background: This study aimed to explore the relationship between frailty and Area Deprivation Index (ADI) among older adults in Korea. Methods: We used data from the Korea National Health and Nutrition Examination Survey from 2014 to 2019, focusing on individuals aged 65 years and older. Frailty was assessed using Fried phenotype of frailty criteria. A multiple logistic regression analysis was conducted to assess the relationship between frailty and ADI adjusted for all covariates. Results: Among 9,825 older adults, those who lived in an area with a high ADI had a 1.2-fold higher risk of frailty compared to those who lived in an area with a low ADI (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.09-1.37). Particularly, married individuals living in areas with a high ADI had an approximately 1.4-fold higher risk of frailty compared to those living in areas with a low ADI (OR, 1.35; 95% CI, 1.16-1.57). Conclusion: This study reveal a significant relationship between frailty and the ADI among older adults. In particular, married individuals who live in areas with a high ADI were found more vulnerable to frailty than those who live in areas with a low ADI. Therefore, policy intervention should be implemented to reduce health inequalities among older people, especially those living in the most deprived areas groups.

This study aimed to identify factors associated with metabolic abnormalities in non-obese and obese postmenopausal women based on biopsychosocial model. Secondary data analysis was conducted using data from 5,335 postmenopausal women who participated in the Korean National Health and Nutrition Examination Survey (2015-2021). According to logistic analysis with applying a complex simple analysis in SPSS 26.0, biomedical (increased age; a family history of hypertension, type 2 diabetes, dyslipidemia, and cardiovascular diseases) and biosocial factors (low educational level) were associated with 1-2 metabolic abnormalities and metabolic syndrome, regardless of adiposity. Additionally, low familial socioeconomic status and prolonged sedentary behaviors were the biosocial and psychosocial factors associated with metabolic syndrome regardless of adiposity. Finally, insufficient physical activity was associated with metabolic syndrome in obese postmenopausal women. Based on these results, tailored strategies should be developed considering the significant factors associated with metabolic abnormalities and adiposity in postmenopausal women.

Sweetpotato [Ipomoea batatas (L.) Lam] grows well in harsh environmental conditions, and is cultivated as one of the top seven food crops in the world. Recently, sweetpotato is drawing interest from people as a healthy food because it is high in dietary fiber, vitamins, carotenoids and overall nutrition value. However, few studies have been conducted on sweetpotato genome sequencing in spite of its importance. This review is aimed at increasing the efficiency of sweetpotato genome sequencing research as well as establishing a base for gene utilization in order to control useful traits. Recently, animal and plant genome sequencing projects increased significantly. However, sweetpotato genome sequencing has not been performed due to polyploidy and heterogeneity problems in its genome. Meanwhile research on its transcriptome has been conducted actively. Recently, a draft of the diploid sweetpotato genome was reported in 2015 by Japanese researchers. In addition, the Korea-China-Japan Trilateral Research Association of Sweetpotato (TRAS) has conducted research on gene map construction and genome sequencing of the hexaploid sweetpotato Xushu 18 since 2014. The Bill & Melinda Gates Foundation launched the 'sweetpotato genomic sequencing to develop genomic tools for Sub-Sahara Africa breeding program'. The chloroplast genome sequence acquired during sweetpotato genome sequencing is used in evolutionary analyses. In this review, the trend of research in the sweetpotato genome sequencing was analyzed. Research trend analysis like this will provide researchers working toward sweetpotato productivity and nutrient improvement with information on the status of sweetpotato genome research. This will contribute to solving world food, energy and environmental problems.

The purpose of this survey was to assess the nutritional status of preschool children a county of Jeju Island. This study used health examinations results for preschool aged children, performed by the public health center of Pukjeju-gun in Jeju-do for over three years from 1999 to 2001, of children in kindergartens and children homes. The target children totaled 5,990 from the ages three to six. For a control group, 316 children from the nearby Jeju-city areas were included as well. The items of this research included height, weight, and hemoglobin values. 1. The average height of boys from ages three to six were 96.35cm, 102.14cm, 109.94cm, 111.00cm respectively, and girls were 94.96cm, 100.93cm, 108.33cm, 110.54cm respectively. The average weights of boys from ages three to six were 15.42kg, 16.93kg, 19.65kg, 19.67kg respectively, and the weight of girls were 14.90kg, 16.45kg, 18.88kg, 19.50kg respectively. 2. The percentages of children who did not reach 90% of the Korean standard height were 4.3% in boys 4.1% in girls. The percentages of children with less than 80% of the Korean standard weight were 7.6% in boys and 6.8% girls. The percentages of children over 120% of Korean standard weight were 10.4% in boys and 11.4% in girls. 3. As for the obesity level, the percentage of boys under-weighed(under 10% for standard weight for height) were 11.6% and girls, 9.5%, and the percentages of boys and girls with obesity($\geq$20%) were 3.6% and 4.4% respectively. 4. The mean hemoglobin value of boys were 11.83g/$d\ell$ and girls, 11.83g/$d\ell$. These were lower than the value of average normal Korean children (12.5g/$d\ell$). The mena hemoglobin values of the children in Pukjeju-gun were considerably lower than that of the children living in Jeju-city(12.3g/$d\ell$) as well. Anemia of Children of Pukjeju-gun were estimated at 38.1%(male) and 37.2%(female), by using Hemoglobin level(<11.5g/$d\ell$ 5. The rates of children included within the normal range of obesity level in Jeju-city and Pukjeju- gun were boys 80.2%, 71.6% in boys, and 77.4%, 72.4% in girls. The percentage of children living in PukJeju-gun included within the normal range were considerably low. 6. There were no changes in the Body Mass Index (BMI) during the three years from 1999 to 2001, but the percentage of children with anemia significantly increased. Health care for preschool aged children, especially in the rural areas, is very important. Centering on public health centers, it is necessary to systematically promote health care in the rural areas.

The purpose of this study was to compare dental health status of South Korean adults, according to the control protocol of glycated hemoglobin A1c (HbA1c). From the measurements of HbA1c levels of 4,991 individuals over the age of 19 who participated in the sixth Korea National Health and Nutrition Examination Survey, the following conclusions were obtained. Glycated hemoglobin was 7.2% in the HbA1c ${\geq}6.6$ diabetic group and 5.9% in women and 8.5% in men. The ratio in the glucose non-control group was higher in the older age group, the lower average monthly household income group, and the lower education level group. Both the tissue health index and functioning teeth index indices were slightly higher in both men and women in the glucose control group. The tissue health index was higher in the younger age group, in the higher average monthly household income group, and in the higher education level group. The missing teeth (MT) index was greater among women (3.775 pieces) than among men (2.317 pieces) in the glucose non-control group. Higher age correlated with a greater number of MT, while higher income and education levels correlated with a lower number of MT. In conclusion, we will continue to provide counseling and education on oral health problems, thereby widening the awareness of the importance of oral health care and providing a variety of media and education methods related to medical and oral health that can manage diabetic patients according to the level of HbA1c It should be developed.

We introduced the physiological responses of aging, active aging and also suggest the impact of physical exercise on body health status and elderly immunity. In this purpose, we searched the Pub Med data base for the articles (include our experimental papers) and review papers having the terms 'Aging', 'Active aging' and 'Physical activity and elderly' in the title, published from 1999 until 2018. The results were as follows: Exercise training has been extensively studied about the reduction of inflammation, oxidative stress, disease, and aging in syndrome X patients and elderly. Combined and aerobic or resistance exercise training could reduce obesity, insulin resistance, type 2 diabetes and hypertension. Exercise training has been extensively studied in cancer settings as part of prevention or treatment strategies. From this research, regular exercise has the potential to target tumor growth through regulation of inflammation and immune responses such as lactate clearance, NK cell activation (innate immunity), activation of cytotoxic immune cells, T cell activation (adaptive immunity), and immune surveillance. However, Endurance physical activity not only induces thermogenesis and diverse sports injuries but also elicits mobilization and functional enhancement of monocytes, neutrophils (which is caused by the cytokine changes such as TNF-alpha, IL-1) whereas it suppresses cell mediated immunity causing to increased susceptibility to inflammation and infections like cough and URTIs (upper respiratory track infections) in young and especially in elderly people. Therefore, Strategies to prevent physical fatigue, sports injuries include avoid overtraining, Adequate recovery and various type of rest during and after physical activity and assuring adequate nutrition supplementation such as glutamine, vitamin B, vitamin C, carbohydrate, ion or berry-contain sports beverages is helpful in physically active elderly.
