The purpose of this study was to study the body cathexis according to the age and the degree of obesity of elderly women. The subjects were 342 elderly women aged 60 to 92. Body measurement and survey were taken from July to August 2001. The results are follows; 1) The subjects showed a tendency to be satisfied with their bodies. But they were relatively unsatisfied with the girth of torso parts. 2) The body cathexis was more influenced by the perceived body size than the actual body size. 3) There were significant differences among the age groups in the body cathexis. The 60∼69 age group was more dissatisfied with their bodies than the other age groups. 4) There were significant differences among groups according to Rohrer Index in the body cathexis. The normal group was more satisfied with their bodies than the lean and the obese groups.

Purpose: This study aimed to investigate the impact of family resilience on caregiver well-being across various age groups of children diagnosed with ADHD (attention-deficit/hyperactivity disorder) groups (0-5, 6-11, and 12-17 years). Methods: Utilizing secondary data from the 2022 US National Survey of Child Health, this cross-sectional study involved 2,752 children who were formally diagnosed with ADHD. Statistical analysis included descriptive analysis, Spearman's rank correlation, chi-square tests, and linear regression, conducted using SPSS version 27. Results: The study revealed a moderate positive correlation (r=.35, p<.001) between family resilience and caregiver well-being. Controlling for covariates, family resilience accounted for 25.2%, 21.1%, and 22.1% of caregiver well-being variance in age groups 0-5, 6-11, and 12-17 years, respectively. Additionally, factors like employment status, family structure, and caregiver age showed varying influences on caregiver well-being across these developmental stages. A consistent pattern emerged across these age groups: unemployment and non-traditional family structures were associated with negative impacts on caregiver well-being, whereas older caregiver age positively influenced well-being. Conclusion: This research underscores the importance of age-specific family resilience strategies to improve caregiver well-being and family interactions in ADHD contexts. Investigating these aspects through qualitative studies across various cultures could deepen our understanding of well-being and inform culturally sensitive interventions.

Objectives: This study was conducted in order to determine how the association between socioeconomic position(SEP) and health status changes with age among Seoul residents aged 25 and over. Methods: We utilized the 2001 and 2005 Seoul Citizens Health Indicators Surveys. We used self-rated 'poor' health status as an outcome variable, and family income as an indicator of SEP. In order to characterize the differential effects of socioeconomic position on health by age, we conducted separate multivariate analyses by 10-year age groups, controlling for sociodemographic covariates. In order to assess the relative health inequality across socioeconomic groups, we estimated the Relative Index of Inequality (RII). Results: The risk of 'poor health' is significantly high in low family income groups, and this increased risk is seen at all ages. However, the magnitude of relative socioeconomic inequality in health, as measured by the odds ratio and RII, is not identical across age groups. The difference in health across income groups is small in early adulthood (ages 25-34), but increases with age until relatively late in life (ages 35-64). It then decreases among the elderly population (ages more than 65). When the RII reported in 2005 is compared to that reported in 2001, RII can be seen to have increased across all ages, with the exception of individuals aged 25-34. Conclusions: The magnitude of health inequality is the greatest during mid- to late adulthood (ages 45-64). In addition, health inequalities have worsened between 2001 and 2005 across all age groups after economic crisis.

Purpose - This research aims to understand the different behaviors of consumers according to cognitive age. Specifically, this research is focused on pro-social behavior. Pro-social behavior is defined as behavior benefiting others, rather than behavior benefiting one's self. It often entails individual risk or cost, such as when giving resources to others, waiting in line, asking for or paying a fair price, or risking one's life in battle. Therefore, we sought to understand consumer psychology and cognitive age as a reflection of inner psychology. People frequently perceive themselves as younger or older than their chronological ages. This self-perceived or cognitive age is a subjective age perception independent of actual chronological age. The discrepancy degree between chronological and cognitive age represents how much individuals perceive themselves as younger than they are. This study examines the gap in donation intention based on cognitive age. In order to investigate cognitive age, composed of four sub-categories (feel-age, look-age, do-age, and interest-age), this study explores the differential donation intention based on cognitive age, which determines the relationship between the young age and old age. Research design, data, and methodology - Data research was conducted by gathering 216 survey samples, excluding those with unreliable answers. Data coding and cleaning were used and SPSS 19.0 software for the data analysis. The respondents were categorized into two types, younger cognitive ages and older cognitive ages. Additionally, we analyzed the moderating variables. In particular, we used cognitive age degree and congruency level (cognitive age low vs. cognitive age high) × (congruency close vs. congruency distant) between - subjects design. First, regression was done to verify the difference between chronological age and cognitive age. Second, a t-test was done to verify the difference of cognitive age level in donations. Third, ANOVA (analysis of variance) was done to verify the difference between cognitive age and congruency in donations. Last, ANOVA was done to verify the difference between cognitive age and moral judgments in donations. Result - The results show most respondents perceive themselves as younger than their chronological ages. In particular, older respondents feel they are younger than their actual age. Moreover, the result of the comparison between low degree and high degree groups of cognitive age, show high donations at the higher degree of cognitive age groups. In addition, the closer the distance to the beneficiaries, the higher the donation in high degree cognitive age groups. The higher moral judgment groups also show relatively high contributions in lower degree cognitive age groups. Conclusions - Donations belong to the category of pro-social behavior reflecting an individual's psychological state. Therefore, it is important in understanding cognitive age. This study implies that it is necessary to take into account both cognitive age and chronological age when segmenting donors. Moreover, this study confirmed that there are different factors affecting the motives behind donations. Thus, it may be utilized to create differential donation strategies.

This paper is to examine the development of Korean young children's judgement on moral and conventional rules. The subjects are 120 children, 30 each at four age levels; age 3(2.8-3.5), age 4(3.7-4.4), age 5(4.8-5.5), and age 6(5.7-6.5) in a day care center in Taegu. Results are summarized as follows: 1. In terms of nonpermissibility, there was a significant difference in regard to the moral and the conventional rule transgression between the group of age 3 years and three groups of ages 4, 5, and 6. 2. In terms of seriousness, there was a significant difference according to domain. Three groups ages 4, 5 and 6 years evaluate moral transgressions to be more serious than conventional transgressions. 3. In terms of rule contingency and generalizability, there was a significant difference in regard to the moral and conventional transgression between the group of age 3 years and three groups of ages 4, 5 and 6. 4. In terms of punishment, there was significant difference according to domain. Three groups of age 4, 5, and 6 years evaluate moral transgressions to be more punishable than conventional transgressions. 5. Children of age 5 with institutional experience do not make a distinction between moral and conventional rules on punishment criterion.

The present study was performed to determine the effect of cold stress on myocardium of aging rat. Control groups, which aged 6, 12 and 24 months, were compared with age-matched experimental groups that were exposed to moderate cold stress for a hours daily in a week at laboratory cold room $(4{\pm}1^{\circ}C)$. The histological, histochemical and ultrastructural changes of myocardium were observed. The results were summarized as follow: 1. Age-dependent histological change of control groups was observed the formation of contraction band in 24months aged group. The experimental groups submitted to cold stress showed a similar change pattern as seen in control groups. However, the degree of change in the experimental groups was significantly larger than that of control groups. In the 34 months aged group the formation of hypercontraction band was observed. 2. Regarding age-dependent histochemical changes of control groups, we observed the increase activities of PAS and Masson's trichrome. In experimental groups the activities of PAS and Masson's trichrome were also increased with age. Compare with control group, the activities of PAS was increased but the activities of Masson's trichrome was decreased. 3. Age-dependent ultrastructural changes on vacuolization, lysosome were observed. In control groups the structural changes occur at 12 months. The accumulation of lipofuscin, contraction band, hypercontraction band and a component of connective tissue were observed in 24 months. However, the degree of change in the experimental groups was significantly larger than that of control groups. In contract, the myelin body in intercalated discs was observed in 24 months of experimental groups.

Purpose:It has been known that the prognosis of a young woman's breast cancer is Poorer than the other woman However, the effect of age on the prognosis is not well-defined We performed this study to investigate age as a prognostic factor of breast cancer. Materials and Methods : A retrospective study was conducted for 3209 breast cancer patients who underwent operations in Department of Surgery, Seoul National University Hospital from January 1981 to December 2000. Patients were divided into two groups, young age(≤35) and old age(>35) groups. And tumor stage, histopathologic characteristics(such as histology, nuclear grade, histologic grade, hormonal receptor, etc), overall survival and disease free survival rates were compared between age groups. Results . The age ranged from 17 to 88 years. 396 patients(12.3%) were included in young age group(median=32) and 2813 Patients(87.7%) in old age group(median=47).There are more advanced stages and poor nuclear grades in young age group(p=0.000, p=0.003), By log-rank test, the young age group had poorer overall survival and disease free survival rates(p<0.05, p=0.0002). Although, the young age group had more advanced TMN stages(p=0.000) and poorer nuclear grade than the old age group(p=0.003) in multi variate analysis, the age was not a significant independent prognostic factor. (P=0.642)Conclusion: Our study showed that the age was not a significant independent prognostic factor.

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.

This study was to investigate the changes in dietary practices, reasons for making dietary changes, current food consumption patterns, and eating habits. Data were collected from 515 parents whose children were attending an elementary school and a middle school in Kimcheon. Among the twenty food groups studied, subjects reported eating more fruit, vegetables, lower-fat meats, high-fat meats, reduced/skim milk, and eggs and less sugar, fats, rice, salt, potato/sweet potato, and chicken. The changes in dietary practices except high-fat meats and salt were significantly different between sex, age, education level, income level, or BMI groups. The primary reason for making dietary changes was 'concerned about family's health'. The average rate of never eating breakfast or less than 2 times per week was found to be 23.2% with a greater rate in younger age group. The rate of breakfast skipping was found to vary between different age and education groups. The regularity of mealtime and overeating practices were significantly different between age groups. Eating out practices were found to vary between different age, education, and income groups. People at younger age group in Kimcheon should be targeted for nutrition education about eating habits. These findings are applicable at the planning and implementation stages of various nutritional improvement projects.
