        This study was conducted to investigate the intake status of beverages and water in Korean adults using data from the 8th National Health and Nutrition Examination Survey. The ‘total water’ intake was 2,250.6 g for men and 1,871.2 g for women. Men and women consumed an average of 314.9 g of ‘total beverages’, of which ‘coffee’ was the largest at 107.5 g, followed by ‘others’(65.4 g), ‘milk’ (44.8 g), ‘soda’ (44.1 g), ‘teas’ (20.9 g), and ‘fruits and vegetables’ (18.5 g). The intake of ’plain water’ was 1,059.9 g, and the intake of ’water from food’ consumed was 547.3 g. The ‘total water’ intake decreased with increasing age in males and females (p<0.001). Both men and women showed a tendency toward increased ‘total water’ intake as income levels increased. ‘Plain water’ intake accounted for 51.4% of the ‘total water’ intake in males and females. The intake of all nutrients significantly increased from the Q1 group to the Q4 group by quartile ranges of total water intake. The results of this study showed that the intake of healthy water should be considered, and care and educational programs are needed, especially for older people, to ensure adequate water intake.

        전 세계 다양한 국가들을 비롯하여 우리나라도 생물다양성을 보전하기 위한 노력에 동참하고 있다. 특히 생물종과 관련해서는 특정 생물종을 대상으로 서식적합분석을 실시하여 잠재적인 서식 적지를 찾고 보전방안을 수립하는 연구들이 활발하게 수행되고 있다. 그러나 현재까지 축적된 정보를 바탕으로 한 서식적합지역의 중장기 변화에 대한 연구는 미흡한 실정이다. 이에 본 연구는 강원도 지역을 대상으로 멸종위기 야생생물 1급으로 지정된 수달을 대상으로 서식적합지역의 시계열 변화를 분석하고 변화 양상을 살펴보고자 하였다. 시계열 변화 분석을 위해서 약 20년간 수행된 2차, 3차, 4차 전국자연환경조사의 수달 종 출현지점 조사자료를 이용하였다. 또한 각 조사시기 별 서식환경을 반영하기 위해 조사시기와 일치하는 토지피복도를 환경변수 제작에 활용하였다. 서식적합지역 분석을 위해서는 종의 출현 정보만을 바탕으로 모델 구동이 가능하며, 선행연구를 통해 신뢰도가 높다고 입증된 MaxEnt 모형을 사용하였다. 연구결과, 각 조사시기 별 수달의 서식적합지역 지도가 도출되었으며, 하천을 중심으로 서식지가 분포하는 경향이 나타났다. 모델링 결과 도출된 환경변수의 반응곡선을 비교하여 수달이 선호하는 서식지의 특성을 파악하였다. 조사시기 별 서식 적지의 변화를 살펴본 결과, 2차 전국자연환경조사를 기반으로 한 서식 적지가 가장 넓은 분포를 나타냈으며, 3, 4차 조사의 서식 적지는 면적이 줄어드는 경향을 나타냈다. 또한, 3개 조사시기 분석결과를 종합하여 서식 적지의 변화 양상을 분석하고 유형화하였다. 변화 유형에 따라서 현장조사, 모니터링, 보호지역 설정, 복원계획과 같이 서로 다른 보전계획을 제안하였다. 본 연구는 수달 서식 적지의 위치와 면적의 시계열 변화를 볼 수 있는 종합분석 지도를 제작하고, 지역별 서식 적지 변화 유형에 따라 필요한 보전계획을 제안하였다는 점에서 의의를 갖는다. 본 연구에서 제안된 방법과 결과는 향후 서식지 보전 및 관리 방안 수립을 위한 기초자료로 활용될 수 있을 것으로 사료된다.

        The purpose of this study was to investigate the current status of chronic diseases according to obesity in the elderly older than age 65 using data from the 7th Korea National Health and Nutrition Examination Survey (2016~2018). The subjects of the survey were 3,245 elderly older than age 65 who participated in the health survey and nutrition survey, 45.8% of the subjects were males and 54.2% of the subjects were female. 37.5% of all the elderly were obese, and the females (42.4%) were more obese than the males (31.8%) (p<0.001). Diabetes, hypertension, and hypertriglyceridemia had a similar prevalence of 24.6%, 63.0%, and 12.7% in males and females, respectively. Hypercholesterolemia was higher in the elderly females (44.2%) than in the elderly males (24.9%) (p<0.001). Through the logistic regression analysis, it was found that the prevalence of chronic diseases was higher in obesity than normal in elderly males and females (p<0.001). The total food intake increased from ‘under weight’ to ‘obesity’ in males (p<0.01) and females (p<0.001). In the case of the elderly males, the higher the degree of obesity, the higher the energy intake (p<0.05), and ‘pre-obesity’ consumed the most energy in elderly females. As a result of this study, the higher the obesity rate of the elderly, the higher the prevalence of chronic diseases.

        This study analyzed the health characteristics and comorbidity of adult men aged 40 years by dividing them into a control group of those without any disease related to fine dust and a patient group with one or more diseases related to fine dust in areas with high levels of fine dust pollution using the sixth and seventh Korea National Health and Nutrition Examination Survey (2013-2017). Among the general characteristics, the mean age of the patient group was significantly older than that of the control group (p<0.001), and in terms of the health-related characteristics, the frequency of breakfast consumption in the patient group was higher than in the control group (p<0.043). The body measurements were similar in the patient and control groups. Regarding the prevalence of comorbidity, the patient group showed a higher prevalence of hypertension, dyslipidemia, stroke, myocardial infarction, heart failure, and diabetes than the control group, but the differences were not statistically significant. On the other hand, the prevalence of other cancers (except stomach cancer, liver cancer, colorectal cancer, breast cancer, and cervical cancer) in the patient group was higher than in the control group (p<0.05). In terms of the clinical characteristics, the glycated hemoglobin levels in the patient group were significantly higher than in the control group (p<0.048). Information on nutrition and health in areas with frequent occurrences of fine dust was obtained through the study results, which can be used as basic data for measures of health and diet management against diseases that will increase in relation to fine dust.

        The purpose of this study was to investigate the association between dietary macronutrient intakes and prevalence of metabolic syndrome (MetS) in Korean adults. Data were obtained from the Korean National Health and Nutrition Examination Survey (2013-2017), and a total of 11,600 Korean adults (4,918 men, 6,682 women) aged 50 years and older were analyzed. The daily intakes and percentages of energy from carbohydrates or fat in men or women with MetS were significantly lower than in normal subjects, respectively. High carbohydrate or fat percentages were negatively associated with MetS based on adjusted odds ratios (OR) of 0.804 in men (p=0.034) and 0.820 in women (p=0.045), respectively. A high percentage of energy from carbohydrates was positively associated with reduced waist circumference, diastolic blood pressure, triglyceride and high-density lipoprotein (HDL) cholesterol in men. On the other hand, a high percentage of energy from fat was positively related with elevated HDL cholesterol and reduced triglycerides in women. In conclusion, our study indicates that high carbohydrate or fat intake is associated with risk of MetS in Korean men or women aged 50 years and older, respectively. Further prospective studies are necessary to elucidate the association between macronutrient intakes and MetS among Korean adults according to age.

        In this study, the Korea National Health and Nutrition Examination Survey in 2016 examined the nutrient and food intake of women in their 20s and 30s according to the number of meals a day, and the results were as follows: The study included 256 women in their 20s and 474 women in their 30s. Women in their 20s and 30s ate two meals a day, indicating that the notion of three meals a day was gradually changing to two to three meals a day. Those in their 20s and 30s who eat one, two or three meals a day were consuming less than the estimated energy requirement of the DRI for Koreans 2015. The vitamin A and C were eating less than the recommended intake in all meals. In the case of minerals, calcium was taken less than the recommended intake in all meals, but sodium was taken above the goal intake in all groups. Women in their 20s and 30s must reduce their intake of saturated fatty acids and sodium, and increase their intake of vitamins A, C, calcium, and potassium. Women in their 20s and 30s drank a lot of coffee, ate baechu-kimchi and rice frequently per week.

        There are an increasing number of reports that job related factors are associated with hypertension, sleep deprivation, obesity and diabetes. This study analyzed the relationship of working type, working hours and the prevalence of metabolic syndrome. The study’s subjects were 2,777 employees (1,446 males and 1,331 females) over 19 years old and their data was from the Korea National Health and Nutrition Survey (2015). The type of work was divided into day work and shift work. The working hours were divided into less than 40 hours, 40 to 49 hours, 50 to 59 hours and 60 hours or more per week. As a result of this study, the prevalence of metabolic syndrome was 26.4% of the males and 19.1% of the females. Generally there was no relationship between metabolic syndrome and type of work (day work and shift work). As a result of analysis of working hours and metabolic syndrome, the workers who worked 40-49 hr were associated with a decreased prevalence of metabolic syndrome as compared to that of workers who worked less than 40 hr (odds ratio: 0.47, 95% confidence interval: 0.24-0.95, p<0.05). Further, positive relationships were found between the number of work hours and the prevalence metabolic syndrome for specific females who worked over 40 hr/wk. It can be concluded from the results that it is important to help workers avoid metabolic syndrome through setting appropriate work hours.

        This study aimed to assess the nutritional quality of breakfast among Korean school-aged children and adolescents depending on eating together as a family, based on the 2013-2014 Korea National Health and Nutrition Survey. One day 24-hour recall data of 1,831 children and adolescents aged from 6 to 17 years were collected. The nutritional quality of breakfast was analyzed and compared between Family Breakfast Group (FBG, n=1,410) and Eating-alone Breakfast Group (EBG, n=421). The results showed that age, family structure, number of family members, and frequency of breakfast were associated with eating breakfast as a family. The calorie intake from breakfast explained 19% and 16% of the daily intake for FBG and EBG, respectively. The percentages of children and adolescents consuming Vitamin A, Vitamin B1, Vitamin B2, Vitamin C, Niacin, and Iron less than 1/4 of the Estimated Average Requirements were significantly lower in FBG than in EBG. The average numbers of serving for “Grains” and “Vegetables” food groups and the average Dietary Diversity Score were significantly higher in FBG than in EBG. Overall, the results indicated that eating breakfast as a family is positively associated with nutritional quality of breakfast among Korean school-aged children and adolescents.

        Although the 1997 Raw Data of the National Wealth Statistical Survey (South Korea) is timely 20-year-old data, it is meaningful as a benchmarking in the capital stock estimations of Korea, which is estimated by PIM (permanent inventory method). In the case of machinery/equipment, it is the data that can analyze in depth the changes in the industrial structure of Korea. In the case of ASL (average service life) which has economic concept, since the change of ASL is not so large, ASL yielded by the Raw Data of the 1997 National Wealth Statistical Survey is meaningful as reference value for the ASL estimated by the Bank of Korea and the National Statistical Office. As you know Japan has changed its service life due to changes in its industrial structure. However, many of its assets are still used for the years indicated in Showa (before 1989). The same trend with other countries such as Japan. However, the United States is constantly devoted to assessing the useful ASL and value of assets by distinguishing between the Hulten-Wykoff models and those not. Korea has also benchmarked the useful ASL of the United States and Japan when it conducted its own survey every 10 years by due diligence until 1997. In this study, the ‘constraint’ Iowa curve estimation by the Raw Data of the 1997 National Wealth Statistical Survey is based on the age records of the assets and the maximum age of the assets appropriately derived. And then we made modified Iowa curve by smoothing. From this modified one, we suggested ASL by asset. After 1997, the vintage disposal data directly were collected by the National Statistical Office with Oh Hyun Seung, Cho Jin Hyung, in order to estimate the useful ASL. Since then, the B/S team of the Economic and Statistics Bureau of the Bank of Korea has been working on a new concept of content training.

        This study aimed to compare energy nutrient intake, health related factors, physical characteristics, blood biochemical indices, prevalence of metabolic syndrome and odds ratio (OR) of metabolic syndrome based on dietary fat energy ratio. Subjects were 1,205 men aged 40~64 years. The average fat intake was 52.8 g. Subjects were divided into three groups (deficient, normal, excess) based on dietary fat energy ratio. The dietary fat energy rations of the three groups were 36.9%, 42.9% and 20.2%, respectively. Energy and protein intake were increased significantly with dietary fat energy ratio (p<0.001), whereas carbohydrate intake decreased (p<0.001). In health related factors, amount of smoking alone showed increase based on dietary fat energy ratio (p<0.001). In comparing physical characteristics, blood pressure and blood biochemical indices, excepting diastolic blood pressure, increased significantly based on dietary fat energy ratio (p<0.01~p<0.001). The rate that exceeded criteria in risk factors for metabolic syndrome was higher in the serum triglyceride (41.2%) and was lower in the waist circumference (22.2%). Prevalence of metabolic syndrome was 37.9%, and showed significant correlation to dietary fat energy ratio (p<0.05). The OR of metabolic syndrome was higher in deficient and excess group than in normal group, but it had no relationship between fat energy ratio and metabolic syndrome. The results of this study provide basic data to establish fat intake guidelines for prevention of metabolic syndrome in middle-aged men.

        This study was conducted to investigate the risk of chronic disease as predicted by abdominal obesity in Korean adult females. Data on 2,738 adult females aged 40~64 yrs was obtained from the 2013~2014 Korean National Health Nutrition Examination Survey. The subjects were divided into normal (n=1,835), abdominal obesity (AO, n=73), and BMI-diagnosed abdominal obesity (BMI-AO, n=505) groups based on the NCEP-ATP III guidelines and by applying the KSSO definition regarding waist circumference. Triglyceride blood levels, fasting blood sugar levels, systolic blood pressure, and diastolic blood pressure were higher in the AO and BMI-AO groups than in the normal group. The HDL-cholesterol levels of subjects in the two abdominal groups were lower as compared to those of subjects in the normal group. The mean adequacy ratio was lower among subjects in the AO and BMI-AO groups than among those in the normal group. Moreover, the NAR and INQ scores of some micro-nutrients in both of the abdominal obesity groups were lower than those in the normal group. Both the AO and BMI-AO groups showed significantly higher risks of hypertriglycemia, hyperglycemia, hypertension, hypoHDL-cholesterolemia, and metabolic syndrome than were shown by the normal group. Notably, as compared to the normal group, the AO group showed higher risk of hypercholesterolemia, hyperLDL-cholesterolemia, hypertriglycemia, and metabolic syndrome than did the BMI-AO group. This finding suggests that it is essential to develop prevention programs including programs for those with abdominal obesity despite their having a BMI within the normal range.
