Whereas systolic blood pressure (SBP) continuously rises with age, diastolic blood pressure (DBP) gradually decreases after the age of 55 years. Therefore, hypertension in the elderly shows the pattern of isolated systolic hypertension. There is evidence on the benefits of controlling blood pressure (BP) in elderly patients with hypertension. The BP lowering effect has also been demonstrated in patients over 80 years of age with hypertension. The BP threshold for the initiation of antihypertensive drug treatment for older adults with hypertension is gradually decreasing. The antihypertensive treatment is recommended if, despite therapeutic lifestyle modifications, SBP ≥140 mmHg or DBP ≥90 mmHg in those aged 65-79 years old, and SBP ≥140-160 mmHg or DBP ≥90 mmHg in those aged ≥80 years old. Although there is no consensus on the target BP for older adults with hypertension, a target SBP of <130-140 mmHg and DBP of <80-90 mmHg are recommended. In older adults over 80 years of age with hypertension, the target SBP is <140-150 mmHg. When the dose of antihypertensive drugs is increased to reach the target SBP, DBP may decrease to less than 70 mmHg, but it should not be <60 mmHg. Thiazide diuretics, calcium channel blockers, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers can be selected as the first-line drug for older adults with hypertension. Beta-blockers may be selected in case of compelling indications.

In order to investigate dietary risk factors for hypertension in th elderly, dietary intakes and dietary habits of 405 elderly subjects, aged 60-94, were assessed by the questionnaire, anthropometric measurement and a 24-hour dietary recall. The prevalence of definite (>95mmHg for diastolic or>160mmHg for systeolic blood pressue) and borderline(90-95mmHg for diastolic or 140-160mmHg for systolic blood pressure) hypertensive subjects 33.3% and 19.3%, respectively. The distribution of the subjects for Body Mass Index(BMI), waist-hip ratio, and alcohol consumption were significantly different among definite, borderline, and normal groups(p<0.05). The distribution of the subjects for smoking, exercise, and preference of salty food were not significantly different among definite, borderline, and normal groups(p>0.05). From the generalized logistic regression analysis of the risk factors for the hypertension, the subjects with over 27 of BMI had significantly higher risk of hypertension. Alcohol consumption and preference of salty food were significant risk factors of hypertension in the elderly. Dietary risk factors for the hypertension that had significant relationship to the hypertension were intakes of potassium, calcium, phosphate, sodium, vitamin B1, niacin, and folate. There was no significant difference of consumption frequencies of food and dish among definite, borderline, and normal groups(p>0.05). The amount of intakes for cereals and grain product, bean and their products, eggs were significantly different among definite, borderline, and normal groups(p<0.05). In summary, the amount of dietary intakes to hypertension in elderly population. Longitudinal studies for dietary risk factors on incidence of hypertension are needed in general population, especially in the elderly.

This paper conducted a feasibility study by applying an Internet of Things and Artificial intelligence-based management system for the elderly living alone in an aging society. The number of single-person families over the age of 50 is expected to increase, and problems such as health, safety, and loneliness may occur due to aging. Therefore, by establishing an IoT-based care system for the elderly living alone, a stable service was developed through securing a rapid response system for the elderly living alone and automatically reporting 119. The participants of the demonstration test were subjects under the jurisdiction of the "Seongnam Senior Complex," and the data collection rate between the IoT sensor and the emergency safety gateway was high. During the demonstration period, as a result of evaluating the satisfaction of the IoT-based care system for the elderly living alone, 90 points were achieved. We are currently in the COVID-19 situation. Therefore, the number of elderly living alone is continuously increasing, and the number of people who cannot benefit from care services will continue to occur. Also, even if the COVID-19 situation is over, the epidemic will happen again. So the care system is essential. The elderly care system developed in this way will provide safety management services based on artificial intelligence-based activity pattern analysis, improving the quality of in-house safety services.

The dietary patterns and characteristics of oldest-old subjects over 85 of Sunchang County (total of 171, 61 males and 110 females) were studied. The average age was $90.6{\pm}3.7$ years old (male; $89.1{\pm}2.8$, female; $91.5{\pm}3.8$), and 90.9% of them were reported to have had no schooling experience. Family types having a spouse were much greater in men (50%) than women (1.8%). The percentages of living alone showed the gender differences, which were comprised of 33% of females and 18.3% of males. In this study, 73.7% of subjects answered "very good" or "good" for their health status. These elderly subjects might maintain their health through a relatively lower rate of smoking (22.2%) and drinking (27.5%), having non-sedentary activities (84.2% of the subjects are physically active) and enough sleep. Their characteristic dietary patterns include high preference of rice (96.5%) and blanch & Seasoned vegetable dishes (Namal, 90.6%) frequent consumption of plant-based food groups containing plenty of anti-oxidants such as vegetables and legumes, and they showed high rates of meal regularity (77.2%) and no skipping of meals (94.2%). It seems to be developed and disseminated in the congregate meal program for improving nutritional status of the elderly, since the coming increment of single-elderly family and single dwellers of rural areas.

The purpose of this study is to identify the quality of life (QOL) and factors influencing the QOL in middle-aged and elderly cancer patients. Among the 2019 data of the Korea Health Panel, data from 498 adults over the age of 40 who were diagnosed with cancer by doctors were analyzed. As a result of the study, the mean QOL of middle-aged cancer patients was 0.90 (±0.09) and that of elderly cancer patients was 0.86 (±0.12). The QOL of middle-aged cancer patients was significantly higher than that of elderly cancer patients. Factors influencing the QOL of middle-aged cancer patients were subjective health status, anxiety, suicidal ideation, and bedridden status. Factors influencing the QOL of elderly cancer patients were subjective health status, bedridden status, economic activity, education level, regular physical activity, stress, and age. In order to improve the QOL of middle-aged and elderly cancer patients, along with interest in the QOL of middle-aged and elderly cancer patients, it is necessary to develop an age-specific intervention program, such as reducing anxiety and suicidal ideation for middle-aged cancer patients, and improving regular physical activity and reducing stress for elderly cancer patients.

The purpose of this study is to propose a specialized clothes-sizing system for elderly (aged 60~79) obese women satisfying the following conditions based on the data from the fifth Korean Agency for Technology and Standards (2004): a Rohrer's index of over 1.6, a BMI of over 25, and a WHR of over 0.85. The lower bodies of elderly obese women tends to be shorter and wider than average. Particularly, their torsos from the chest to the waist tend to be more obese than other areas. According to the KS standards, the clothes-sizing system sets up its size intervals as follows: 5cm in stature, 5cm and 3cm in bust, 3cm in waist, and 3cm in hip. Based on the dualistic distribution of each section, the names of the sections indicating high distribution are suggested. For suit tops, 11 sizes are selected as distributed in the 145-155cm stature section and 91-103cm bust section. For casual tops, nine sizes are selected as distributed in the 145-155cm stature section and 90-105cm bust section. For bottoms, 11 sizes are selected as distributed in the 82-97cm waist section and 91-97cm hip section. According to the KS standards, detailed sizes are suggested in the division of basic and reference areas.

Using the first wave of the Korean Longitudinal Study of Ageing, this research examines the effect of elderly parent's financial structure on private income transfers from their adult children. The results show that low income elderly households are more likely to receive income transfers from their children. Generally, Korean elderly households were found to have very low liquidity in their asset structure, as the average household holds over 90% of their assets in real estate. However, it seems that the parents' potential income based on their real estate assets is unimportant in determining children's transfer decisions. Rather, the parents' labor income is found to be a key factor in children's income transfer decisions.

Purpose: This study aimed to investigate the perception of dental implant insurance supply and demand for the elderly living in Hongseong-gun and Chungcheongnam-do, as well as the selection criteria regarding dental clinics for dental implant treatment to collect basic data for improving the oral health of the elderly population. Methods: Participants living in Hongseong-gun, Chungcheongnam-do who were at least 55 years old from November 2020 to March 2021 were included in this study. The chi-square test was performed to examine the age-specific perception of insurance-covered dental implants (p<0.05). Results: The age group that was the most interested in implants was the 70s age group, and the difference between this age group and the other age groups was statistically significant. Those in their 70's, 80's, and 90's or older paid about 600,000 won including dental implants covered by insurance, and there was a significant difference (p<0.05). Those in their 60s, 70s, and 80s estimated the highest value of implants covered by insurance as two and showed a significant difference (p<0.05). The awareness of the dental implant insurance by age showed that all age groups, except for the ≥90 years age group, considered the insurance to be mediocre mostly due to the large co-payment (p<0.05). Conclusion: There were differences by age in the awareness of dental implant insurance, co-payments, number of applications, and insurance coverage. The perceptions on dental implant insurance by age showed that all age groups except for those over 90 years and older, they considered the insurance was just mediocre the most.

The purpose of the study was to investigate the influence of salt (NaCl) recognition threshold and pleasant salt concentrations of Korean rural elderly subjects on preference of salty food as well as food group consumption patterns. The subjects were 213 elderly people (male 71 and female 142) over 65 and under 90 yr of age from Sunchang area. The higher values were found with male subjects in the areas of basic taste recognition threshold and pleasant concentration level of salt. The taste sensitivity scores of male subjects did not decrease with the increasing age, but female subjects exhibited a significant decrease with the age. The major determinant factor of salt preference of the elderly subjects in this study appeared to be personal pleasant concentration of salt rather than salt recognition threshold level and this trend was more evident in males than in females. The subject group of lower salt pleasant concentration i.e. consuming less salt showed the higher number of fruit and fruit juice intakes per week, and higher MNA (define this) scores were implying that they display more desirable nutritional status. Therefore, nutritional education focused on not only a variety of food consumption but also lowering pleasant salt concentration levels is advised to improve the quality of nutrition in the elderly.

This study was performed to investigate the perception and preferences regarding commercial universal design foods (UDF) made with different ingredients. A one-to-one interview was used for data collection and the survey was conducted on 41 elderly people (over age 65; males: 11, females: 30) attending senior welfare centers in Seoul. Twelve UDF samples were collected, which were widely sold in Japan. Majority of respondents prepared meals (53.7%) and ate alone (43.9%), respectively. The preferred cooking level of elderly food was "ready to eat (RTE)" (43.9%) or "ready to heat (RTH)" (43.9%) rather than fresh cut product. In most, the elderly had no problem with chewing-action (90.2%). Generally, food ingredients such as grain, meat, seafood and fruits showed higher preference than vegetable and nuts. Among 12 UDF samples, pumpkin gratin (4.17) and peach flavored jelly (4.27) showed higher preferences among tested samples on a 5-point facial hedonic scale. There were no significant differences in overall preferences of all samples by difficulty in terms of chewing and swallowing of respondents. Demi-glace sauce hamburger and pot sukiyaki were more preferred as age increased (p<0.05).
