This study aims to discover the relations between physical activities of the elderly and their health-related quality of life. For the study, it targeted 720 of the 778 elderly persons whose ages were above 65 for a final analysis except 58 whose physical activities and health-related quality of life could not be evaluated from the data of the first year of the 4th Korea National Health and Nutrition Examination Survey(KNHANES IV-1), 2007. As a result, it was discovered that there were significant differences in the elderly's health-related quality of life according to age, education, sleeping hours, stress, the number of chronic diseases and subjective awareness of health. In particular, there were significant differences in their health-related quality of life between the group with high physical activity level and the group with low physical activity level. Based on the results above, it is suggested that the persons with higher performance ability of physical activities can have higher quality of living along with increase of energy and further studies dealing with more factors, ranges and periods are needed.

Unmet healthcare is an important indicator to measure accessibility of healthcare services. To examine the latest status of unmet healthcare needs in South Korea, the four different data which is composed of nationally representative sample of South Korean population were used; the Korea Health and Nutrition Examination Survey (KNAHANES, 2007-2019), the Community Health Survey (CHS, 2008-2019), the Korea Health Panel Survey (KHP, 2011-2017), and the Korean Welfare Panel Study (KOWEPS, 2006-2019). The proportion of individuals reporting unmet healthcare needs were 5.8% (KNHANES), 5.3% (CHS), and 11.6% (KHP). Annual percentage change (APC) which identifies trend for the follow-up period was -9.5%, -8.0%, and -6.5%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.1% (KNAHANES), 0.7% (CHS), 2.4% (KHP), and 0.4% (KOWEPS). The APC was -10.5%, -14.2%, -12.2%, and -19.6%, respectively. Compared to last year, the rate of unmet healthcare needs has declined in general. However, the low-income and the elderly population were reporting the highest rate of unmet health care needs, and the disparity between lowest and highest groups were remained. These results suggest that adequate benefit coverage is needed for low-income and elderly population.

Objectives: The purpose of the study is to investigate the relationship between oral health status and body mass index (BMI) in adults over 65 years old. Methods: The study subjects were 4,550 adults over 65 years old from the 5th Korea National Health and Nutrition Examination Survey(KNHANES V) in 2010-2012. Mastication-related oral health status included the number of remaining teeth, and mean number of decayed, missing, and filled permanent teeth(DMFT). Body mass index(BMI, $kg/m^2$) was categorized as underweight(<18.5), normal weight (18.5-22.9), overweight(23.0-24.9), and obese(${\geq}25.0$). Multinomial logistic regression analysis was performed to examine the association of BMI categories with the number of remaining teeth and DMFT. Results: The mean number of DMFT was highest($13.0{\pm}0.7$) in the underweight group and lowest($8.8{\pm}0.3$) in the obese group. Those having less favorable masticatory ability, and fewer number of remaining teeth and no prosthesis, tended to be underweight. Those having a higher number of remaining teeth and prosthetic teeth tended to be overweight or obese. In the multinomial logistic regression analysis, compared with those having 20 or more remaining teeth, including prosthetic teeth, those having less than 20 remaining teeth and no prosthesis had 4.48 times higher odds ratio of being underweight. DMFT was positively associated with underweight, while negatively associated with overweight or obesity. Conclusions: The masticatory ability and dental caries prevention maintained the healthy body weight in adults of old age.

Objectives: This study was performed to compare the diet quality and diversity according to types of obesity categorized by body mass index and waist circumference among Korean adults aged 19-64 years. Methods: This study used the data of the 5th Korea National Health and Nutrition Examination Survey (KNHANES-V) and included 11,081 study participants. Type of obesity was categorized into 4 groups (Type 1: BMI obesity + abdominal obesity; Type 2: BMI obesity only; Type 3: abdominal obesity only; Type 4: Normal). To compare the diet quality and diversity according to obesity type, ANCOVA (Analysis of covariance) was used with stratification of age groups (19-44 years, 45-64 years). Results: With regard to comparative analysis of diet quality, there were significant differences between diet qualities in energy, protein, thiamin, riboflavin, niacin, phosphorous and iron and type of obesity in the 19-44 age group, while there were significant differences between diet qualities on protein, vitamin C, phosphorous and type of obesity in the 45-64 age group. There was no significant difference between diet diversity score and type of obesity in Korean adults. Conclusions: This study showed that in Korean adults, diet qualities of some nutrients were different among obesity types, while diet diversity was not. These observations should be considered in an effort to improve intake of over-and deficient nutrients and in further studies to evaluate the effects of nutrient quality on obesity.

The purpose of this study was to investigate the relationship between age, physical activity (walking, strength exercise), subjective body shape recognition, and weight change with subjective health status in the population aged 30 years or older among the data of the National Health and Nutrition Examination Survey (2018) of Koreans. The subject and method of this study was a secondary analysis study using the 7th 3rd year National Health and Nutrition Examination Survey (2018). Age, walking days per week, strength training days per week, subjective health status, subjective body shape recognition, and weight change during the year were used the SPSS (p<.01). The response rate of walking for 7 days (every day) was 21.9% for those aged 30-45, 27.2% for those aged 50-64, and 26.6% for those aged 65 or older. aged 8.4% and over 65 years old 7.9% (p<.001). The subjective health status was positively correlated with age (.091), number of walking days per week (.739), number of days of strength exercise per week (.530), subjective perception of body shape (.256), and weight change over one year (.303). There was a relationship (p<.01). In this study, the age group that answered 'bad' in subjective health status was the highest at 21.4% of those aged 65 or older, followed by 15.7% of those aged 50-64 and 11.0% of those aged 30-45. This could be expected to improve subjective health status by walking and strength training. Based on these results, it was intended to provide basic data for preparing health-related programs to improve subjective health status of individuals according to age.

This study investigates the factors influencing quality of life for cancer patients based on demographic characteristics, physical-mental health, and oral health. These factors are analyzed using the results from 235 cancer patients in Korea's 7th national health and nutrition survey. Data were analyzed using PASW Statistics Ver. 18.0. Studies show that cancer patients experienced stress (74.5%), depression (84.3%), and activity limitations (15.3%). In oral health, problems chewing were often experienced in groups with low incomes (3.35±.21), activity limitations (2.71±.31), and depression (3.01±.27). The factors influencing quality of life were higher by 3.43 times in the low-income group and by 8.39 times in the activity-restricted group, by 2.74 times in the high-stress group, by 4.58 times in the depression group, by 2.68 times in the chewing-problems group, and were 4.92 times higher in the speech problems group (p<0.05). To improve quality of life, not only mental and physical health care, but also oral care is necessary. An integrated management plan for medical staff in the treatment process of cancer patients is required to prevent mental, physical, and oral discomfort.

Purpose: This study was to identify health behavior, health service use, and health related quality of life of adult women in one-person and multi-person households. Methods: It was used data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII-2017). Subjects were 2,522 women with age of 19 to 64 years in 2017. Complex sampling design and data analysis were performed using SPSS 20.1. Results: Women in one-person households had higher rates of alcohol drinking (${\chi}^2=13.77$, p=.003), smoking (${\chi}^2=16.07$, p=.001), unmet medical care (${\chi}^2=8.77$, p=.004) and non-practice of cancer screening (${\chi}^2=13.77$, p=.003) compared to women in multi-person households. Health-related quality of life was also lower for women in one-person households (t=-2.46, p=.015). Factors affecting health-related quality of life in one-person households were household income, job status, and unmet dental care, having 32.4% explanatory power. One-person household women with low incomes, no jobs, and unmet dental care showed low health-related quality of life. In comparison, factors affecting health-related quality of life of women in multi-person household women were age, education level, unmet medical care, and unmet dental care, having 10.4% explaining power. Women in multi-person households with age of 60-64, low education level, unmet medical care, and unmet dental care showed low health-related quality of life. Conclusion: Health promotion strategies should be developed based on unique understanding of social, economic, and health of adult women in one-person and multi-person households.

The intake of processed foods containing high levels of sugar increases the incidence of chronic diseases, including obesity, diabetes, and metabolic syndrome. Limiting sugar intake is important for a healthy life at all ages. Therefore, this study analyzed food sources and sugar intake by the different age groups based on the 7^th Korea National Health and Nutrition Examination Survey (KNHANES). We used 24-hour recall survey data to investigate the daily sugar intake and the major food groups and main dishes contributing to sugar intake. The mean sugar intake was 58.9-66.8 g/day. The three major food groups contributing to sugar intake were fruits (15.2-19.9 g/day), beverages (10.7-12.4 g/day), and milk and milk products (7.6-7.8 g/day). Teas and other non-alcoholic beverages (14.7-17.3 g/day), fruits (12.5-16.2 g/day), and dairy products (7.0-7.6 g/day) were the major food groups that contributed to the sugar intake. Carbonated drinks, apples, and milk were the top sources of sugar intake in each group. In conclusion, the sugar intake of Koreans is mainly from carbonated drinks, fruits, and milk. These results provided the basic data for nutrition education and nutrition program development according to the different age groups of the Korean population.
