Purpose: This study was conducted to help with the development of an intervention program in efforts to prevent suicidal ideation and suicide. The study also sought to generate strategies for improving health conditions by ascertaining and analyzing potential factors that may influence suicidal ideation according to age group in adults. Methods: Data on general characteristics and suicidal ideation from 447 adults aged between 20 and 59 years, living in Y city, Gyeonggi Province, South Korea, were collected based on a structured questionnaire, The data were analyzed using SPSS20.0 statistics program. Results: The results showed that 48.6% of young and older adults have experienced suicidal ideation while 44.5% of middle-aged adults have had suicidal thoughts. With regard to suicidal ideation, young and older adults revealed relevant differences in terms of gender, residential type, degree of stress and subjective physical and mental health, while middle-aged adults revealed relevant differences in terms of marital status and degree of stress. With regard to factors that influence suicidal ideation, it was found that the relevant variables of young and older adults included gender, residential type, depression, degree of stress, and subjective physical and mental health, while for middle-aged adults, relevant variables included marital status and degree of stress. Conclusion: These findings indicate that as stress and depression decreases, subjective physical and mental health improves. Therefore, this study proposes that developing and operating an intervention program can help prevent suicidal ideation in local residents.

[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.

Skinfold thickness measurement and total body fat calculation were made in summer (July) and winter (December or January) On 70 medical students (age: 20 yr),8 national team basketball players (age: 20 yr), and 9 middle-age men. Skinfold thickness measurements were made on 4 sites, namely, back, arm, waist and abdomen. The mean skinfold thickness (mm) of the 4 sites was substituted into the following formulae. For adult of 20 years old: % Fat=0.911x+8.1, and for middle-aged men % Fat=1.199x+1.41. In young medical students and ball players body weight decreased, mean skinfold thickness increased in winter season. As a result total body fat .(% body weight) increased in winter In middle-aged men both body weight and mean skinfold thickness increased in winter and resulted in an increase in the total body fat. The detailed data are as follows: 1. In medical students summer: winter values were: body weight, 59.7 :58.9 kg; mean skinfold thickness, 7.85 : 8.12 mm; and total body fat, 15.0 : 15.5% body weight (P<.30). 2. In national team basketball players summer: winter values were: body weight, 73.5 : 69.1 kg; mean skinfold thickness, 7.2 : 7.5 mm; total body fat, 11.6 : 12.1% (P:NS). 3. In middle-aged men summer vs winter values were: body weight, 61.5 : 63.0 kg; mean skinfold thickness, 10.3 : 11.8 mm; total body fat, 17.2 : 18.0% (P:NS). 4. Skinfold thickness on back showed no seasonal variation and on abdomen the thickness increased in winter. 5. It was concluded that the predominant factor in increasing total body fat in winter is the decrease in body exercise in the winter time.

The objective of this study was to investigate nutritional status of middle aged Korean men exhibiting impaired glucose tolerance (IGT) and identify the risk factors related to IGT Data were collected from 163 men with a fasting blood glucose level from 115 to 139mg/dl(high blood glucose group: HBG) and 170 men with a normal fasting blood glucose level(control) aged from 40 to 59 years in both groups. Weight, body mass index(BMI) and percent body fat were significantly higher in high blood glucose(HBG) group than those of control group. Age, weight, BMI, percent body fat were positively related to blood glucose. There were no differences in exercise, smoking and family history of diabetes between two groups. Frequency of fat eating and overeating of HBG were higher than those of control group but frequency of sweet snacks intake of HBG was lower than that of control group. There was no difference in daily total energy intake in two groups. Total and supper energy intakes were positively associated with blood glucose. Percent energy intake of alcohol was significantly higher in HBG group and positively related to blood glucose, however there were no difference in daily intake of nutrients in two groups. Alcohol intake was positively related to BMI, but after adjusting BMI, there was no correlation between alcohol intake and blood glucose. Serum total cholesterol and triglyceride were significantly higher in HBG group than those of control group. Serum total cholesterol i,nd triglyceride were positively related to blood glucose and high density lipoprotein cholesterol was negatively associated with blood glucose. After adjusting BMI, serum triglyceride was positively related to blood glucose. In conclusion, weight, BMI, percent body fat and blood total cholesterol, low density lipoprotein cholesterol and triglyceride levels were positively related to blood glucose level of middle aged Korean men exhibiting impaired glucose tolerance. Their eating habits exhibited higher frequency of overeating, fast eating, high energy intakes of supper. (Korean J Nutrition 33(1) : 59-67, 2000)

The purpose of this study was to investigate the effects of 12-week circuit weight training on their body composition and physical fitness in middle aged women. A total of 34 subjects of did not have any physical abnormalities or diseases, and the subjects were 12-week circuit weight training. The results of this study were as following : Body composition component examination showed that the body weight, body fat percentage and waist measurement showed differences that were statistically significant. And the physical fitness component examination showed that muscular endurance, flexibility, agility, and cardiovascular endurance showed differences that were statistically significant. But muscular strength and reflexes showed differences that were not statistically significant. These results suggest that the circuit weight-training had an effect on body composition and physical fitness examination results over 12-week. Therefore, we consider that the circuit weight training is recommended to middle-age women to improve body fat percentage and physical strength.

The study attempted to examine the structural model of the effects of health status and retirement aging anxiety on middle-aged workers. The subjects were collected from 263 40-59 year old middle-aged workers who work at three institutions in C and G cities. Results First, the variables affecting aging anxiety were aging preparation and health status, and these variables accounted for 52% of aging anxiety. Second, health status had a significant effect on retirement preparedness, and there was a significant indirect effect on aging anxiety through retirement preparedness. There was a partial control effect due to the difference in the path coefficient between health status and aging anxiety in the multi-group moderating effect of 40~49 and 50~59 years. Therefore, in order to reduce aging anxiety, it is important to find ways to prepare for various retirement, and a systematic management system is necessary.
