This study examined apartment residents' energy-lifestyle, and their energy consumption patterns by energy-lifestyle. The major findings are as follow: 1)In order to identify energy lifestyle, three dimensions - value of life, energy consuming behavior and energy awareness - were defined by literature reviews, and each dimension was tested to define components. 2)The scores of the 14 factors that were defined by factor analysis on the three dimensions of the energy lifestyle were subject to cluster analysis, and then lifestyle was categorized into five groups. G1 is very negative, and indifferent to energy waste or saving at home. G2 is passively carrying out energy saving activities at home, only within their comfort. G3 is aware of energy saving, and more actively keeping energy saving behavior in their everyday lives, while they also show energy waste behavior at the same time. G4 is particularly indifferent to energy costs, and presenting energy squandering behaviors. G5 is better aware of energy saving than other groups, and carrying out energy saving behaviors in their everyday lives. This study would be of help to establish energy saving management and education plans in apartments.

BACKGROUND/OBJECTIVE: Apolipoprotein A5 gene promoter region T-1131C polymorphism (APOA5 T-1131C) is known to be associated with elevated plasma TG levels, although little is known of the influence of the interaction between APOA5 T-1131C and lifestyle modification on TG levels. To investigate this matter, we studied APOA5 T-1131C and plasma TG levels of subjects participating in a three-month lifestyle modification program. SUBJECTS/METHODS: A three-month lifestyle modification program was conducted with 297 participants (Age: $57{\pm}8years$) in Izumo City, Japan, from 2001-2007. Changes in energy balance (the difference between energy intake and energy expenditure) and BMI were used to evaluate the participants' responses to the lifestyle modification. RESULTS: Even after adjusting for confounding factors, plasma TG levels were significantly different at baseline among three genotype subgroups: TT, $126{\pm}68mg/dl$; TC, $134{\pm}74mg/dl$; and CC, $172{\pm}101mg/dl$. Lifestyle modification resulted in significant reductions in plasma TG levels in the TT, TC, and CC genotype subgroups: $-21.9{\pm}61.0mg/dl$, $-20.9{\pm}51.0mg/dl$, and $-42.6{\pm}78.5mg/dl$, respectively, with no significant differences between them. In a stepwise regression analysis, age, APOA5 T-1131C, body mass index (BMI), homeostasis model assessment-insulin resistance (HOMA-IR), and the 18:1/18:0 ratio showed independent association with plasma TG levels at baseline. In a general linear model analysis, APOA5 T-1131C C-allele carriers showed significantly greater TG reduction with decreased energy balance than wild type carriers after adjustment for age, gender, and baseline plasma TG levels. CONCLUSIONS: The genetic effects of APOA5 T-1131C independently affected plasma TG levels. However, lifestyle modification was effective in significantly reducing plasma TG levels despite the APOA5 T-1131C genotype background.

Hypertension is a well-known risk factor for cardiovascular disease. Previous studies have shown that changes in diet and lifestyle factors can prevent the development of hypertension, but the combined effects of these modifiable factors on hypertension are not well established. The objective of this study is to investigate associations of diet and lifestyle factors, evaluated both individually and in combination, with prevalent hypertension among Korean adults. We analyzed data obtained from the 2007-2008 Korean National Health and Nutritional Examination Survey, a nationwide cross-sectional study using a stratified, multistage probability sampling design. The associations of 12 nutrient intakes and lifestyle factors with risk of hypertension were explored using restricted cubic spline regression and logistic regression models among 6,351 adults. Total energy and several nutrients and minerals, including, calcium, vitamin A, vitamin C, and sodium, showed non-linear relationships with the risk of prevalent hypertension. In multivariate logistic regression models, dietary score, obesity and alcohol intake were independently associated with the risk of prevalent hypertension, but smoking and physical activity were not. Overall, participants whose dietary habits and lifestyle factors were all in the low-risk group had 68% lower prevalence of hypertension (OR: 0.32, 95 CI: 0.14-0.74) compared to those who were at least one in the high-risk group of any dietary or lifestyle factors. The result suggests that combined optimal lifestyle habits are strongly associated with lower prevalence of hypertension among Korean adults.

The purpose of this study was to examine the pre-service elementary teachers' perceptions and attitudes toward sustainable development. Subjects were 152 university students, who were surveyed by questionnaire. The instrument consisted of totally 41 items which were constructed by 3 components; 'the perception of concept of sustainable development', 'the attitude toward the relationship between economy and environment' and 'the practical intention of personal change for sustainable lifestyle'. The key findings suggest that most students associate strongly the concepts of sustainable development with their environmental as against economic and social aspect. Most of them incline toward eco-centrism but they had complex attitudes concerning the relationship between economy and environment. They have intention to act for sustainable lifestyle such as purchasing habits, recycling, energy water saving, forms of transportation, nature conservation and education. However, they prefer to act passively than actively in a certain aspect of sustainable lifestyle. Understanding of pre-service elementary teachers' perceptions of and attitudes toward sustainable development will be helpful to work out teaching and learning strategies in environmental education.

Purpose: Cancer-related fatigue is frequently experienced by patients during and after therapy. The present study was conducted to assess the impact of energy conservation strategies and health promotion in breast cancer survivors. Methods: A randomized controlled trial was carried out to compare the intervention effect (n=69.0) with controls (n=66.0) based on routine oncology ward care. The intervention was five weekly sessions for groups of 6-8 breast cancer survivors. Data on fatigue and health promotion lifestyle were obtained before and after completion the intervention and then 8 weeks later for analysis of variance (ANOVA) with repeated measures. Results: Our findings showed cancer-related fatigue to be reduced in the intervention group from pre- to post-intervention, and this persisted over the 8-weeks follow-up period (F = 69.8, p<0.001). All subscales of the cancer fatigue scale demonstrated statistically significant effects with partial eta-squared values ranging from 0.15 (the smallest effect in cognitive fatigue) to 0.21 (the largest for affective fatigue). Changes in the health promotion life style indicated a significant promotion from pre- to post-intervention, and this again continued after 8-weeks follow-up (F = 41.6, p < 0.001). All six domains of a health promoting life style featured significantly elevated values, the largest effect being seen in the interpersonal relations subscale (F=57.7, partial ${\eta}^2=0.21$, p<0.001) followed by physical activity (F=51.9, partial ${\eta}^2=0.18$, p<0.001). Conclusions: The program was effective in decreasing cancer related fatigue and promoting a healthy lifestyle.

This study aims to determine the association between obesity-related behaviors (dietary practices, physical activity and body image) and body weight status among adolescents. A total of 382 adolescents (187 males and 195 females) aged 13 to 15 years in Kajang, Selangor participated in this study. Majority of the respondents were Malays (56.0%), followed by Chinese (30.1%) and Indians (13.9%). Dietary practices, physical activity and body image of the adolescents were assessed through the eating behaviors questionnaire, two-day dietary record, two-day physical activity record and multi-dimensional body image scale (MBIS), respectively. Body weight and height were measured by trained researchers. The prevalence of overweight and obesity (19.5%) was about twice the prevalence of underweight (10.5%). About two-thirds of the respondents (72.3%) skipped at least one meal and half of them (56.2%) snacked between meals with a mean energy intake of $1,641{\pm}452$ kcal/day. More than half of the respondents (56.8%) were practicing sedentary lifestyle with a mean energy expenditure of $1,631{\pm}573$ kcal per day. Energy intake (r = 0.153, P < 0.05), physical activity (r = 0.463, P < 0.01) and body image (r = 0.424, P < 0.01) were correlated with BMI. However, meal skipping, snacking and energy expenditure per kg body weight were not associated with body weight status. Multiple linear regression analysis showed that body image, physical activity and energy intake contributed significantly in explaining body weight status of the adolescents. In short, overweight and obesity were likely to be associated not only with energy intake and physical activity, but also body image. Hence, promoting healthy eating, active lifestyle and positive body image should be incorporated in future obesity prevention programmes in adolescents.

Taking vitamin and mineral supplements is increasingly common with the rapid economic growth. The aim of this study was to determine the prevalence of vitamin and mineral supplement use among adults aged 20 or older from the third Korean National Health and Nutrition Survey data and to explore the effect of sociodemographic and lifestyle factors as well as nutrient intake on taking supplements. People who had participated in both a health questionnaire and a nutritional survey were selected, and 2,871 men and 3,555 women were finally included in this analysis. Both men and women with a higher level of education, those residing in a metropolitan area, and those with higher income were more likely to take supplements. Health behaviors were not significantly associated with taking supplements. Mean nutrient intake of all nutrients except energy intake was not significantly different in men or women taking supplements after adjusting for age, education, marital status, resident area, smoking, and energy intake. Compared to Dietary Reference Intake (DRI) for Koreans, most vitamins and minerals, except vitamin $B_2$ and calcium, were consumed at higher than the Recommended Intake (RI) without supplements. In conclusion, taking supplements such as vitamin $B_2$ and calcium may promote health and prevent disease. However, the type and frequency of other vitamin and mineral supplements consumed should be considered with caution.

This study was performed to investigate the relationship between obesity, health-related lifestyle, and dietary intake and serum lipid level in 96 male university students. Health-related lifestyle factors were obtained from questionnaires. Dietary intakes were evaluated with one-day 24-hr recall and two-day dietary record. Anthoropometric data were recorded and serum cholesterol and triacylglycerol concentrations were measured. 21.9%, 36.5%, 36.5%, and 6.2% of the subjects had levels beyond the normal range in serum total cholesterol(TC), HDL-cholesterol(HDL-C), LDL-cholesterol(LDL-C), and triacyglycerol respectively, and 57.3% of the subjects had more than one hyperlipidemic factor. TC was correlated positively with BMI(p〈0.01), waist length(p〈0.05), hip length(p〈0.05), and the amount of smoking(p〈0.05). HDL-C was correlated negatively with BMI(p〈0.05) and hip lenghth(p〈0.05). LTD-C was correlated positively with BMI(p〈0.01), water length(p〈0.05), hip length(p〈0.01), and coffee consumption(p〈0.05). TG was correlated positively with waist length(p〈0.01), waist-to-hip ratio(p〈0.05), and amount of smoking(p〈0.01) and negatively correlated with frequence of exercise(p〈0.05). Among nutrient intakes, only the ratio of protein to energy was correlated negatively with TC(p〈0.05). Logistic regression analysis revealed that BMI, waist length, hip length, waist-to-hip ratio, and amount of cigarette smoking were associated with an increased risk of hyper-TC. BMI, waist length, and hip length were associated with an increased risk of hypo-HDL-C. BMI and coffee consumption were associated with an increased risk of hyper-LDL-C. Amount of cigarette smoking was associated with an increased risk of hyper-TG. In conclusion, a high prevalence of hyperlipidemia in subjects was observed. Also obesity, smoking, and coffee consumption were observed to be highly with the risk of hyperlipidemia in subjects. These findings imply that these factors should be primarily considered in planing the nutrition education program for the prevention of cardiovascular disease in male university students.
