  • Adipocytokines (adiponectin, leptin and resistin) are known to play a major role in development of cardiovascular disease (CVD) and intervention program is effective in reducing CVD risk factors. However, intervention program to improve the CVD risk factors including adipocytokines has been less studied. This study investigated the effects of 12-weeks worksite intervention program on cardiovascular risk factors, adipocytokines and nutrients intakes in industrial workers. 157 industrial male workers (32 metabolic syndrome (MS) subjects, 125 healthy subjects using age-matched stratified random sampling) received 5 face-to-face counseling based on their health profiles. Anthropometry, biochemical parameters and nutrients intakes were measured. The diagnosis of MS was adapted from modified NCEP-ATP III criteria (2001) and Asia-Pacific definition criteria (2000) for waist circumference (WC). After the intervention program, WC, BMI, SBP, insulin, leptin and intakes of total energy and fiber were significantly decreased (p < 0.05), while adiponectin was significantly increased (p < 0.05) in MS subjects. The WC, BMI, SBP, total cholesterol, LDL and HDL-cholesterol, HbA1c, leptin and intakes of total energy, protein and fat were significantly decreased (p < 0.05) and adiponectin was significantly increased (p < 0.05) in normal subjects. Multiple linear regression revealed that adiponectin was positively correlated with HDL-cholesterol (p < 0.01). Leptin was positively correlated with WC (p < 0.01), and resistin was positively correlated with HbA1c (p < 0.05) and intakes of total energy (p < 0.05), and negatively correlated with HDL-cholesterol (p < 0.05). The results of the 12 weeks intervention showed a positive impact on adipocytokines and nutrients intakes of industrial workers to reduce cardiovascular risk factors. Further research is needed to verify a tailored long-term worksite intervention program including adipocytokines as a protective factor for the CVD.

  • This pilot study was performed to produce data of the Children's Dietary Life Safety (CDLS) Index which is required by the Special Act on Safety Management of Children's Dietary Life and to evaluate the CDLS Index for 7 metropolitan cities and 9 provinces in Korea. To calculate the CDLS Index score, data regarding the evaluation indicators in the children's food safety domain and children's nutrition safety domain were collected from the local governments in 2009. For data regarding the indicators in the children's perception & practice domain, a survey was conducted on 2,400 5th grade children selected by stratified sampling in 16 local areas. Relative scores of indicators in each domain were calculated using the data provided by local governments and the survey, the weights are applied on relative scores, and then the CDLS Index scores of local governments were produced by adding scores of the 3 domains. The national average scores of the food safety domain, the nutrition safety domain and the perception and practice domain were 23.74 (14.67-26.50 on a 40-point scale), 16.65 (12.25-19.60 on a 40-point scale), and 14.88 (14.16-15.30 on a 20-point scale), respectively. The national average score of the CDLS Index which was produced by adding the scores of the three domains was 55.27 ranging 46.44-58.94 among local governments. The CDLS Index scores produced in this study may provide the motivation for comparing relative accomplishment and for actively achieving the goals through establishment of the target value by local governments. Also, it can be used as useful data for the establishment and improvement of children's dietary life safety policy at the national level.

  • Intention to smoke is a valid and reliable factor for predicting future smoking habits among adolescents. This factor, however, has received inadequate attention in Malaysia. The present paper elaborates the prevalence and factors associated with intent to initiate or to cease smoking, among adolescent nonsmokers and smokers in Kota Tinggi, Johor, Malaysia. A total of 2,300 secondary school students aged 13-16 years were selected through a two-stage stratified sampling method. A set of standardized questionnaires was used to assess the smoking behavior among adolescents and the inter-personal and intra-personal factors associated with smoking intention (intention to initiate smoking or to cease smoking). Multivariable logistic regression was used to identify factors related to smoking intention. The prevalence of intention to smoke in the future or to cease smoking among non-smoking adolescents and current smokers were 10.7% and 61.7% respectively. Having friends who smoke, social influence, and poor knowledge about the ill effects on health due to smoking showed significant relationships with intention to smoke in the future among non-smokers. Conversely, perceived lower prevalence of smoking among peers, weak contributory social influence, and greater awareness of the ill effects of smoking are factors associated with the intention to cease smoking sometime in the future. The study found that prevalence of intention to initiate smoking is low among non-smokers while the majority of current smokers intended to cease smoking in the future. Existing anti-smoking programmes that integrate the factors that have been identified in the current study should be put in motion to reduce the prevalence of intention to initiate smoking and increase the intention to cease smoking among adolescents.

  • The objective of this study was to examine job satisfaction status and its related factors among dietitians working in hospitals. A survey questionnaire was sent to dietitians working in tertiary, general, and convalescent hospitals in Korea. The study sample hospitals included all tertiary hospitals (n=43), and the sample of general hospitals (n=114) and convalescent hospitals (n=240) was randomly selected using a stratified sampling method. A total of 665 dietitians completed the survey questionnaire. The questionnaire included 27 job satisfaction questions on task, stability vision, working conditions, and relationship areas, and the questions on task improvement need. The job satisfaction scores in all four areas ranged from 2.53/5.00 to 3.89/5.00, implying generally low job satisfaction level in hospital dietitians. The job satisfaction levels in the convalescent hospital group were significantly lower compared to those in the tertiary and general hospital groups. Whereas job satisfaction levels of tertiary and convalescent hospital groups did not differ by number of beds, those of the general hospital group increased significantly with the number of beds for all four areas. Multivariate regression analysis results showed that hospital type was a significant predictor of job satisfaction level for all four areas. Job satisfaction of relationship area was also significantly affected by the number of beds, whereas that of working conditions was influenced by annual income and working experience. The study findings provide useful information in planning clinical dietitians' optimal supply outlook for the improvement of clinical nutrition services.

  • This study examines the effect of working conditions for care workers on the care quality in long-term care facilities, particularly the coexisting perspective on publicness and the marketization of Long-term care services in South Korea brings about. Prior studies have not identified a causal relationship between working conditions and the care quality, only explained cause of a low-wage labor market and low productivity of social services. Theoretical relevance of working conditions and service quality on Long-term care in Korea is to view from a integrated care model by Daly and Lewis(2002). A nonproportional stratified sampling procedure was used to consider Long-term care facility's ownership. A merged dataset combining surveys from 248 Long-Term Care facilities and online resources from NHIC administrative was used and analyzed by multiple regression. The analysis results is showed as follows. Overall, organizations with better working conditions, having higher wage, having greater a fringe benefit, being skills development and training are likely to have good care quality in each area. This research shows that the working conditions, rewards and support to care workers of organizational culture in the normative dimension beyond the minimum standard on labor market policy and evaluation system by government regulations have a positive impact on Long-term care quality.

  • The purpose of this study was to analyze the path that the elderly discrimination experiences and sense of loss lead to suicidal ideation by verifying the influence of the elderly's discrimination experience on suicidal ideation and the mediating effect of sense of loss. To this end, questionnaire a survey was conducted on 400 elderly people aged 65 years or older who used 10 elderly welfare centers using stratified sampling of 31 cities, counties, and districts in Gyeonggi-do. Additionally, a total of 380 samples were finally analyzed excluding dishonest responses. As a result of the study, first, the more individual and social discrimination experiences, which are sub-factors of the elderly discrimination experience, increased suicidal ideation. Second, individual discrimination experiences were found to has a static effect on suicidal ideation through partial mediation of sense of loss. Third, the experience of social discrimination showed a static effect on suicidal ideation by perfect mediating the sense of loss. Therefore, it was found that the sense of loss acts as a risk factor for the elderly's suicidal ideation. Based on the research results, the urgent need for institutional supplementation to prevent the elderly's social discrimination experiences was suggested, and practical implications for preventing elderly suicide by resolving the sense of loss in the elderly welfare practice field were suggested.

  • The purpose of this study was to investigate the home care needs in a rural county as a basic study to develop a Korean home care model. A stratified cluster sampling method was used to select 1, 352 household which accounted for 8.8% of Youn Cheon County population. A Standard criterias for home care subject were delineated by five nursing professors representing five different areas of nursing specialty. The developed criteria for home care subjects were as below, 1) Patients who had been discharged from hospital during the previous week. 2) Patients with special medical devices 3) Newborns and the mothers. 4) The chronically ill with poor recovery or control of disease. 5) Subjects with poor health care behavior or ability 6) Subjects with poor social support and / or family resources. 7) Subjects with health related educational needs. Three types of questionnaires were developed to screen home care subjects, one for adults, one for infants and one for the elderly. Also different questionnaire items were developed to evaluate the control and self care ability of chronically ill subjects. After training in interview methods for 2 days, 39 interviewers visited individual households for interviews. As the results of the study showed that 14.1% of adult subjects and 76.5% of infants and child were judged as having at least one criterion related to home care need, 15.69% of adults and 53% of elderly had at least one chronic illness. The most prevalent chronic illnesses were hypertension, skeletal-neurological disease and diabetes. The prevalence of subjects with home care needs were, those with poor health care behavior(8.89%), with health-re-lated educational needs(8.71%), with poor recovery or control of disease (3.52%), and with poor social support and inadequate family resources(3.19%). There were only 0.3%, 0.37%, 0.11% who were discharged patients, patients with medical devices, or newborns respectively. Thus, the largest home care client group were those who need direct health care and health education. Seventy five percent of the subjects responded that they were willing to use and pay for home care service if it is offered in the future. It is suggested that recently discharged patients and patients with special medical devices can be cared for by hospital based home care nurses, but other home care clients can be cared for by com-munity based home care nurses.

  • Objectives: This study was performed to investigate the changes in the prevalence and its related factors of the Clonorchis sinensis(C.S.) in the inhabitants at Goksung-Gun along Sum-Jin river after C.S. control intervention. Methods: The subjects were 416 among 699 in the 8 same villages selected by stratified cluster sampling in 1999. The formalin-esther sedimentaion technic was used for the C.S. egg detection and the questionnare for the related factors. The study was carried on from February, 2005 to March, 2005. Results: The prevalence of C.S. decreased significantly from 19.0% in 1999 to 11.3% in 2005. The signicicant factors in 1999 such as sex, age, area, raw fish eating habit and drink habit were not significant statistically. On the other hand factors such as the awareness of C.S. and the health behavior were changed significantly(p=0.034, p=0.021). Conclusions: These results suggest that C.S. prevalence became lower than previous study five years ago. But its control intervention should be extened to the general population regardless of sex, age, area, raw fish eating habits, drink habit and we need to make an effort to improve the awareness and the health behavior of C.S..
