This study investigated the risk factors of hypertension among individuals under and over 65 years of age. A total of 6,152 participants were analyzed using the 6th Korean Longitudinal Study of Aging. The collected data were analyzed by Chi-square tests and logistic regression using SPSS 23. The results showed that the subjective health status, diabetes, heart disease, and degree of obesity according to BMI were risk factors affecting hypertension in individuals both under and over age 65. In adults under age 65, chronic lung disease, digestive disease, and drinking were risk factors affecting hypertension. In elderly over age 65, region, arthritis and rheumatic disease, smoking, and cognitive function were risk factors affecting hypertension. There is a need for chronic disease management in Korea due to rapid aging. In particular, it is important to analyze for effective management age-related risk factors affecting steadily increasing hypertension with age. Therefore, it is necessary to manage chronic disease management through social welfare improvement and welfare plans for the elderly, as well as personal management.

The purpose of this study was to investigate the correlation between glycemic load and blood lipid profiles in some Korean according to age: The subjects were divided into four groups based on the following age ranges; $10\sim19$ age group(n=260), $20\sim49$ age group(n=129), $50\sim64$ age group(n=135), over 65 age group(n=87). They were measured for the anthropometric measurements, dietary intakes, glycemic load and blood analysis. The average ages of the $10\sim19$ age group, $20\sim49$ age group, $50\sim64$ age group and over 65 age group were 10.9 yrs, 40.8 yrs, 57.1 yrs and 70.8 yrs, respectively. The food intakes were increased according to age in the younger two groups but decreased in the elder two groups. The energy and carbohydrate intakes were the highest in the $10\sim19$ age group. The averages of serum HDL-cholesterol levels of the $20\sim49,\;50\sim64$ and over 65 age group were significantly lower than that of the $10\sim19$ age group. The food intake of the $10\sim19$ age group was positively correlated to the glycemic load(p<0.001). The food and energy intakes of the $20\sim49,\;50\sim64$ and over 65 age group were positively correlated to the glycemic load. And the serum triglyceride and AI levels of the over 65 age group were positively correlated to the glycemic load(p<0.001, p<0.05). These results suggest the need for further research into the relation between glycemic load and blood lipids in order to ensure proper carbohydrate intakes.

The purpose of this study was to evaluate the prevalence of obesity, dietary habits, and nutritional status by age among low-income women, using data from the fourth Korea National Health and Nutrition Examination Survey (2007~2009). Subjects were 8,356 women aged 20 and over. The subjects were classified into four groups by age. Dietary data from 24-hr recall methods were used to analyze nutritional status. The prevalence of obesity in the 50~64 years age group was significantly higher than those of the other age groups. Among age groups, malnutrition was the highest in the 65-and-over age group. It appears that women in the 20~29 and 65-and-over age groups were the highest nutritional risk. The percentage of carbohydrates in total energy intake was higher and the percentages of protein and fat were lower in the 65-and-over age group than other groups. Frequency of skipping breakfast was lower in women aged 65-and-over, and moderate physical activity significantly decreased with increasing age. Awareness of dietary guidelines was higher in women aged 30~49 years than other groups, whereas it was lower in those aged 65-and-over years. Adherence to dietary guidelines of 'eating a variety of foods from each food group' was significantly lower in women aged 65-and-over years than those of other groups. However adherence to dietary guidelines of 'eating breakfast everyday with a pleasant mind' was significantly lower in women aged 20~29 years than those of other groups. Therefore, this study shows that low income women have various nutritional problems by age group, and we should support a tailored approach to improve their nutritional status.

The commercial pilot retirement age has continued to 65 since the International Civil Aviation Organization(ICAO) amended the recommended age limit from 60. The target of this review is to analyse whether aged pilots have an increased age-dependent risk of medical incapacitation. Medical in-flight incapacitation is actually very rare event and the demonstrated annual incapacitation rate provides an acceptable risk within the criteria known as 1% safety rule for a pilot undertaking air transport operations while some controversies exist. There is a possibility that the accident rate has decreased due to the improved skill by increasing pilot's age. At the decision of flight or not for elderly airline pilot the interacting factors of personal health status, piloting experience and new flight environments should be considered to define job limit criteria than mere the age. Results of a survey led by airline pilot association in Korea shows 65% of airline pilots are willing to fly without any age limit and 87% agreed that age limit is worthy to extend beyond current standard on the basis of medical examinations. Only 11% agreed to maintain current age limit.

Objective: Older persons with diabetes mellitus (DM) are particularly more likely to have fallen in the previous year than those without DM. The purpose of this study was to investigate the relationship between the risk of falls and type 2 DM in older adults who are 65 years of age or above. Design: A systematic review. Methods: PubMed and other two databases were searched up to August 2, 2018. Observational and cohort studies evaluating fall risk in people who are 65 years of age or above with DM were included. This review extracted the following information from each study selected: first author's surname, year of publication, country, average follow-up period, sex, age at enrollment, study population, measurement variables, relative risk, 95% confidence intervals and controlled variables. Results: This review involved nine cohort studies with 3,765 older adults with DM and 12,989 older adults without DM. Six studies compared with or without DM and two studies compared fallers with non-fallers with DM. Risk factors for falls included impaired cognitive function, diabetes-related complications (peripheral nerve dysfunction, visual impairment), and physical function (balance, gait velocity, muscle strength, and severity of physical activities). Conclusions: People who are 65 years of age or above with DM have increased risk of falling caused by impaired cognitive function, peripheral nerve dysfunction, visual impairment, and physical function in community-dwellers. For adults who are 65 years of age or older with DM, research fields and clinical settings should consider therapeutic approaches to improve these risk factors for falls.

The purpose of this study was to describe the gait pattern and parameters of the healthy elderly over 65years of age by the GATERite system. The subjects were sorted into two groups, depending on their sex: male and female. And female subjects were sorted into three groups, depending on their age. From time parameters and space parameters of gait cycle, between groups, the following results were made. The time parameters such as cadence, velocity, step time, single support and double support were the less the male than the female. And the higher age, the lower value except 80 age group, while no statistically significant. The space parameters(step length and stride length) were the longer the male than the female, and the higher age, the lower value while no statistically signigicant. The functional ambulation profile was high correlation with time and space parameters statistically significant.

BACKGROUND/OBJECTIVES: The Dietary Reference Intakes for Koreans (KDRIs) were revised in 2020. Due to the rapidly aging Korean population, special consideration was given to reclassify the KDRI age group categories of older adults. This article examines the evidence for modifying the current KDRI age group ranges of older adults (65-74 and ≥ 75 yrs). SUBJECTS/METHODS: We first reviewed the domestic and international data on the elderly, following which we received expert opinions on age classification from the KDRI Advisory Committee. Finally, the 6th and 7th (2013-2017) Korea National Health and Nutrition Examination Survey (KNHANES) data were used to analyze the nutritional intake statuses by considering the age of older adults. RESULTS: According to the review results of domestic and international data and the inputs received from the expert advisory committee, the minimum age considered for the elderly was maintained at 65 yrs. However, the KNHANES data was analyzed to review whether there was a need to subdivide the later periods. Examining the differences in nutrient intakes by age group through the interaction effect term of the piecewise linear regression model revealed the interaction effect was maximum in the groups divided by 65 yrs (50-64 and 65-80), as compared to the groups divided by 70 yrs (50-69 and 70-80) and 75 yrs (50-74 and 75-80). The mean adequacy ratio was calculated per 1 yr of age, and a 3-yr (age) moving average analysis was performed to examine the change in the trends of overall nutrient intake. However, it was challenging to secure a scientific basis for subdivision into age groups in older adults from the results obtained. CONCLUSIONS: This study could not find any scientific evidence for modifying the KDRI age groups for older adults.

Malnutrition affect clinical outcomes in hospitalized old age patients, but the data on the related outcomes on the basis of different age categories are still limited. We aimed to investigate the interplay of associations among body mass index (BMI), falls risk, and mortality rate in different older adult patient age categories. This retrospective study included hospitalized patients aged ≥ 65 years who received artificial nutrition. Demographic, biochemical, and survival data were collected. BMI was evaluated using the World Health Organization BMI cutoffs for Asians, and patients were classified into high (≥ 23.0 kg/m²), normal (18.5-22.9 kg/m²), and low (< 18.5 kg/m²) BMI groups. The Morse Fall Scale was used to assess falls risk. By age categories, all patients (n = 4,642) were divided into the 65-74 (n = 2,649) and ≥ 75 (n = 1,993) years age groups. We found that the proportion of low-BMI and high risk of falls increased with age. Further, low-BMI was associated with increased falls risk in both age groups. Overall survival rate tended to be lower in the low-BMI and ≥ 75 years group than that in other patient groups, but did not differ significantly compared with the low-BMI and 65-74 years group. Low-BMI was associated with increased falls risk and mortality; however, the association depended on specific patient age groups.

This study targeted 501 the elderly ages 65 or over in three places including the Senior Welfare Center and the college for seniors located in Daegu City and Gyeongsangbuk-do. The study results on the preference for oral health care management items across different ages showed that the age group of 65~69 fluoride application; the age group of 65~74 scaling and education of brushing; the age group of 70~74 denture cleaning and maintenance; the age group of 75 denture production. In the relationship between the self-perceived oral condition and the items of oral health care management, respondents who currently have a poor oral condition or have greater chewing trouble, or have higher dry mouth, preference the manufacturing of dentures in most cases. Respondents who have a lower number of teeth or wear dentures preference dentures cleansing and management in most cases. Respondents who have shaking teeth or have frequent tooth pain preference tooth extraction. Since the preference for oral health care management items may differ by their age or oral condition, oral health management customized to each individual should be applied.

Background: Increasing age has been observed among patients admitted to the intensive care unit (ICU). Age traditionally considered a risk factor for ICU mortality. We investigated how the epidemiology and clinical outcomes of older ICU patients have changed over a decade. Methods: We analyzed patients admitted to the ICU at a university hospital in Seoul, South Korea. We defined patients aged 65 and older as older patients. Changes in age groups and mortality risk factors over the study period were analyzed. Results: A total of 32,322 patients were enrolled who aged ≥65 years admitted to the ICUs between January 1, 2007, and December 31, 2017. Patients aged ≥65 years accounted for 35% and of these, the older (O, 65 to 74 years) comprised 19,630 (66.5%), very older (VO, 75 to 84 years) group 8,573 (29.1%), and very very older (VVO, ≥85 years) group 1,300 (4.4%). The mean age of ICU patients over the study period increased (71.9±5.6 years in 2007 vs. 73.2±6.1 years in 2017) and the proportions of the VO and VVO group both increased. Over the period, the proportion of female increased (37.9% in 2007 vs. 43.3% in 2017), and increased ICU admissions for medical reasons (39.7% in 2007 vs. 40.2% in 2017). In-hospital mortality declined across all older age groups, from 10.3% in 2007 to 7.6% in 2017. Hospital length of stay (LOS) decreased in all groups, but ICU LOS decreased only in the O and VO groups. Conclusion: The study indicates a changing demographic in ICUs with an increase in older patients, and suggests a need for customized ICU treatment strategies and resources.
