Purpose: The purpose of this study was to examine late-onset hypogonadism, erectile dysfunction, depression, and quality of life among middle-aged male workers. Methods: The subjects included 343 men aged between 40 and 64, responded to self-report questionnaires on general characteristics, late-onset hypogonadism, erectile dysfunction, depression, and quality of life. Data were collected from May 16, 2012 to October 9, 2012 and analyzed using t-test, ANOVA, $x^2$-test, hierarchical multiple regression. Result: The prevalence rate of late-onset hypogonadism was 63.8% with high points in reduction of libido, energy, physical strength and endurance, and erectile function. There were significant differences in late-onset hypogonadism according to age($x^2$=8.98, p=.048) and in erectile dysfunction according to age(F=11.03, p<.001), monthly income(F=2.84, p=.024) and smoking( t=2.96, p=.018). Significant differences were also found in depression according to educational level(F=8.12, p<.001) and in quality of life according to monthly income(F=7.21, p<.001). The factors which influenced quality of life were late-onset hypogonadism, erectile dysfunction, depression, marital status and religion. Conclusion: Symptoms of erectile dysfunction can be improved by smoking cessation education program. In order to improve the life quality of middle-aged men, nursing intervention programs that would both provide proper knowledge on climacteric syndrome and alleviate symptoms should be designed while, at the same time, other programs to evaluate, prevent and control depression are developed.

The purpose of this study was to examine the fitness of a Path model to represent relations between stress, social support, depression, and suicidal ideation in middle-aged males. The participants were 236 middle-aged males, and data were collected from April 11 to June 1, 2018. The analysis was performed using descriptive statistics and Pearson's correlations in PASW Ver. 21.0, and AMOS Ver. 18.0 (a statistical structural equation modeling program), fitness characteristics of the final model were RMSEA 0.05, GFI 0.98, AGFI 0.95, and NFI 0.98. The major study results were as follows. First, stress had a direct effect on depression and drinking, and social support had a direct effect on depression. Second, stress and social support both directly affected suicidal ideation. Results also suggested depression had partial mediating effects on relations between stress, social support, and suicidal ideation. We suggest a program be devised to reduce suicidal ideation by middle-aged males. It is hoped our results will provide basic data for future studies.

[Purpose] This preliminary study aimed to develop a regression model to estimate the resting metabolic rate (RMR) of young and middle-aged Koreans using various easy-to-measure dependent variables. [Methods] The RMR and the dependent variables for its estimation (e.g. age, height, body mass index, fat-free mass; FFM, fat mass, % body fat, systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse pressure, and resting heart rate) were measured in 53 young (male n = 18, female n = 16) and middle-aged (male n = 5, female n = 14) healthy adults. Statistical analysis was performed to develop an RMR estimation regression model using the stepwise regression method. [Results] We confirmed that FFM and age were important variables in both the regression models based on the regression coefficients. Mean explanatory power of RMR₁ regression models estimated only by FFM was 66.7% (R²) and 66.0% (adjusted R²), while mean standard errors of estimates (SEE) was 219.85 kcal/day. Additionally, mean explanatory power of RMR₂ regression models developed by FFM and age were 70.0% (R²) and 68.8% (adjusted R²), while the mean SEE was 210.64 kcal/day. There was no significant difference between the measured RMR by the canopy method using a metabolic gas analyzer and the predicted RMR by RMR₁ and RMR₂ equations. [Conclusion] This preliminary study developed a regression model to estimate the RMR of young and middle-age healthy Koreans. The regression model was as follows: RMR₁ = 24.383 × FFM + 634.310, RMR₂ = 23.691 × FFM - 5.745 × age + 852.341.

The purpose of this study was to identify 1) the effect of two contexts (job interview, Informal outing) and clothing cues (type, style, color) on male impresssions 2) the effect of perceiver's age on male impressions created by the clothing cues and contexts. The subjects consisted of 256 male undergraduate students and 256 middle-aged men. The experimental materials developed for this study were a set of stimuli and response scales. The stimuli were 8 color photographs of drawings of a male figure in clothing which were manipulated in two levels, each of three clothing cues including type, style and color. The experimental design was full factorial design of $(2^4contex^2{\times}clothing type^2{times}clthing color^2$. Each of the 16 sub-samples includes 16 subjects from the two perceiver group. Questionnaires used to measure perceivers responses to the stimuli were 7-point semantic differential scales composed of 37 bipolar adjectives representing personal traits. The data was processed by factor analysis, ANOVA, multiple classification analysis, Duncan's multiple range test. The major findings drawn from this study were as follows: 1. Three factors emerged to account for the dimensional structure of the impressions of the male figure in clothing in two social situations. These factors involved evaluation, activity and uniqueness. 2. The contexts, clothing types and clothing styles had significant effects on evaluation, activity and uniqueness. The clothing styles had a considerable effect on both evaluation and uniqueness while the clothing types affected activity. The clothing color had least effect on the impression and had only moderate effect on evaluation. 3. Perceiver's age influenced impressions formed by the social contexts and clothing cues. Male college students were least affected by contexts and clothing cues, while middle-aged men wert affected most.

This research investigated how the participation of various social activities affects cognitive function in middle-aged and elderly population. To examine the relation between the participation of various social activities and cognitive function, we used data from the Korean Longitudinal Study of Ageing. Social activities were classified into four types as religious ritual, leisure, public association and ascriptive association activities, and MMSE-K score was used to measure cognitive function. Results from multiple regression analyses after adjusting for socio-economic status and health status show that the participation in religious and leisure activities have positive effects on cognitive function in middle-aged and elderly population. Participation in leisure activities in middle-aged male group helps preserve cognitive function, and leisure activity and ritual activity are significantly related to cognitive function in middle-aged female group. Meanwhile the participation in religious and leisure activities have positive effects on cognitive function in elderly male and female group. Based on these findings, we suggest that various programs to support the participation of elderly population in social activities should be developed for healthy life for the elderly.

The survey was conducted by using questionnaires in order to investigate the expectation of over middle aged people on dietary living during their elderly life. Many persons(41.9%) anticipate that some kind of change will happen in dietary living during their elderly life. They are willing to prepare their own meals by themselves (73.5% of male and 86.6% of female). It is expected that they prefer various kinds of foods, korean traditional foods, home-made foods, natural food to processed food, and nutritionally balanced foods. The balance of nutrition and easiness of digestion should be primarily considered as a base of food choice, and then taste or convenience. The result of this study indicates that korean traditional food culture can not be easily changed. If food industries had a plan to produce some items for future silver generation, they should make efforts to develop processed foods considered the nutrition and digestibility, natural foods packed conveniently for home-cooking, and food preparation equipment used easily by elderly people.

Purpose: This study aimed to identify types of quality of life (QoL) based on the 5 dimensions of EQ-5D and predict factors affecting types of QoL. Methods: This study was a secondary analysis using data from the Korean Health Panel Survey-II(2012). Participants were 2,071 middle-aged men who had completed the additional survey in 2012 and the data were analyzed using SPSS 20.0 and Mplus 5.21 for latent analysis. Results: Three latent classes of QoL were identified: serious (2.4% of the sample), threatened (15.5%), and stable types (82.0%). The types and characteristics of QoL among the latent classes differed. On comparing latent type 1 with latent type 2, the socioeconomic status (p<.05), employment status (p<.05), and subjective health status (p<.001) were found to be significant. On comparing latent type 1 with latent type 3, the socioeconomic status (p<.05), current smoking status (p<.001), and subjective health status (p<.001) were found to be significant. On comparing latent type 2 with latent type 3, the socioeconomic status (p<.05), subjective health status (p<.001), stress (p<.001) were found to be significant. Conclusion: The results showed significant heterogeneity in types of QoL and the predictors of QoL by types were different. These findings provide basic information for developing nursing interventions to improve QoL. Specific characteristics depending on the subtypes should be considered during the development of interventions.

In order to investigate supplement use in middle-aged and elderly outpatients suffering from age-related diseases over the last year, a cross-sectional survey was conducted from July to December 2001. The subjects were 1702 (male 731, female 971) age-related disease outpatients over age 50. Data was collected using a standardized questionnaire and in-person interviews. The prevalence of supplement use and the different categories of supplements taken by the subjects were examined using SPSS statistical package. Supplements were used by 48.9% of the subjects. The mean number of kinds of dietary supplements taken by subjects was 1.7. Chinese medicine was the most commonly used supplements in both the male and female subjects. Among the reasons for using supplements, health promotion ranked as the most common. Most of the supplement users, however, did not know or only knew roughly about the health claims of their supplements. Subjects reported the information source on supplements as family, friends or relatives followed by doctors or pharmacists. These results may provide basic information for proper supplement use among Korean middle-aged and elderly outpatients with age-related diseases.
