The purpose of this study was to develop, implement and evaluate a nutrition education program for middle aged men at a worksite. To be read easily, induce interest, and selected at need, seven 6-page leaflet aets were developed, which was the most preferable from chosen by the subjects. The contents of leaflet set were [Changing life style], [Good food habit],[Weight control and diet],[Cardiovascualr disease and diet], [Alimentary disease and diet],[Diaabetes and diet],and [Liver disease and diet]. Nutrition education was provided for 61 middle aged men(30 professors, 31 office workers) at a worksite from 40 mins to one hour. And the level of nutrition knowledge and nutrition attitude were tested to evaluate the effects of the nutrition education program with a developed leaflet set before and after nutrition education. After the nutrition deucation. the nutrition knowledge score had increased significantly at p<0.001, from average 9.3 point to 11.4 point. The level of nutrition knowledge was increased significantly at p<0.001, and the prevalence of misconceptions and the uncertainty of knowledge were decreased significantly at p<0.05. There was a significant difference between professors and office workers both before and after the program. Also, there was a significant increase in the attitude about nutrition score after the program and this means that the subjects were flexibly more open minded about nutrition than before(from 39.9 point, at p<0.001). The difference in the nutrition attitude score between professors and office workers was not significant both before and after the nutrition deucation. The developed leaflet set was evaluated very positively in understanding, interest, timing, and usage by the subjects.

In Korea, the practice of nutrition education program at the worksite has not yet been implemented, especially for the workers who are at risk for health. Accordingly, the worksite nutrition program, education, and nutrition counseling are necessary. In this study, the worksite nutrition program was developed from June, 1997 to May, 1998. For this program, we surveyed the workers' age and the levels of education, income and physical activity. We developed the proper dietary intake questionnaire to evaluate the employees' nutritional status and the nutrition index which is a simple tool to assess nutrient intakes of the employees at the worksites. To demonstrate the validity of the developed nutritional assessment tools, the CAN(Computer Aided Nutritional) program and Hyunmin system developed by the Korean Nutrition Society and the Korean Dietetic Association respectively, were used as references. The result of the validity test for the dietary assessment method that we have been developed revealed that the method was valid showing no significant difference among the various methods. However, the carbohydrate intake measured by the CAN program was higher than those of others. The validity test results for the nutrient index method showed that there was no significant difference among the methods, except the carbohydrate intake measured by the Hyunmin system was lower that those of others. As a result, we concluded that the dietary assessment methods that we had been developed, were valid method to measure the nutrient intakes of the employees at the worksites.

In Korea, nutritional services have not been included in the periodic medical examinations for employees. Naturally, the practice of individual dietary treatment, or nutrition education, has not yet been implemented, specifically for employees who are expected to encounter health problems. This study was designed to evaluate the necessity and development of nutritional consultations during medical examinations of employees and of worksite nutrition programs. One hundred and five employees from three companies were chosen as subjects for this study. As a result, the average intake of nutrients were found to be sufficient for male employees but female employees were found to be deficient in their intake of total calories, calcium, iron, vitamins A and $B_2$. Also, most of employees did not recognize their own blood cholesterol levels, blood pressure, or blood sugar level. Many employees thought that they needed nutritional consultation during periodic medical examinations and during worksite nutrition programs that also include programs for the whole family. According to the results, clinics for weight control were urgently demanded among several nutrition programs. It should be noted that weight problems, high blood cholesterol levels, diabetes, and other health problems were frequently found in companies whose employees had relatively minimal knowledge about nutrition information. In an effort to prevent disease, the worksite nutrition programs and other nutritional services for employees are critical. This study, therefore, suggests to include nutritional services in medical examinations and to develop efficient worksite nutrition programs.

Objectives: To investigate the effect of a worksite-based dietary intervention program for the management of metabolic syndrome (MS) among male employees. Methods: A dietary intervention program combining individual and environmental approach was implemented targeting white-collar employees at a worksite located in Seoul for 10 weeks. Out of 104 employees having agreed to participate in the program, those having three or more out of five components of MS and having two components, including a waist circumference component were classified into "the high risk group" (n=41) and received group nutrition education and individual nutrition counseling three times each. The rest of the study subjects were considered as "the low risk group" (n=63). The food environment at the worksite, where both the high and low risk groups were exposed, was changed to promote healthy eating. Physical data including MS components were collected and a questionnaire on dietary behaviors was administered before and after the intervention. The data from the high risk group (n=17) and the low risk group (n=20), excluding the subjects ineligible for or failed to complete the study (n=67), were analyzed. The difference before and after intervention was tested for significance by Wilcoxon signed-rank tests. Results: Weight, body mass index (BMI), waist circumference, blood pressure, HDL-cholesterol, and HbA1c and the healthy dietary practice score improved significantly after intervention in the high risk group. The median number of MS components decreased significantly from 3.0 to 1.0 in the high risk group. In the low risk group, only HbA1c significantly decreased. Conclusions: The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees.

Purpose: The purpose of this study is to identify the types of worksite health promotion programs. Method: Data were collected from the excellent 35 cases chosen at the contest for worksite health promotion held by Korea Occupational Safety and Health Agency. Result: Out of all the health promotion programs, the exercise program recorded 35.0%, the nutrition program 29.4%, the smoking cessation program 28.0%, and the alcohol reduction program 7.6%. The major element of worksite health promotion programs were awareness raising intervention. Behavior change intervention and supportive environment intervention occupied a small portion of the health promotion programs. Evaluation of health promotion programs was made mainly by indicators of health behavior change and clinical symptom. Yet economical indicator was not used at all. Conclusion: Use of various evaluation indicator and development of various interventions including behavior change and supply of supportive environment are required to encourage worksite health promotion program.

Worksite health promotion programs have been associated with reductions in health risks but are labor-intensive and costly to implement. Therefore, innovative strategies to provide a cost-effective approach to health education program are needed. The purpose of this study was to investigate the effects of a worksite on-line health education program by email on metabolic syndrome risk factors and dietary intakes in male workers with metabolic syndrome. Anthropometric and biochemical parameters were measured and the nutrient intakes were assessed through FFQ. The diagnosis of metabolic syndrome was adapted from NCEP-ATP III with blood pressure, fasting blood glucose, triglyceride, HDL cholesterol, and Asia-Pacific definition with waist circumference. The education group consisted of 212 male workers and the non-education group of 236 age-matched male workers. The on-line health education program provided 10 sessions by e-mail. After a worksite on-line health education program, systolic blood pressure (p < 0.001), diastolic blood pressure (p < 0.001) and fasting blood glucose (p < 0.001) were significantly decreased and HDL cholesterol (p < 0.001) was significantly increased in the education group. Intakes of total energy (p < 0.05), carbohydrate (p < 0.05), sodium (p < 0.05) were significantly decreased in the education group, but there were no significant differences in dietary intakes in the non-education group after a worksite on-line health education program. The results indicate that online health education program by e-mail is effective for improving metabolic syndrome risk factors and dietary intakes in male workers and show potential for use in the working setting.

The purpose of this research was to determine barriers that prevent participation in an employee wellness program, Wellness Wednesdays: "Eat & Meet" About Healthy Living, conducted at East Carolina University (ECU) in Greenville, North Carolina. All ECU ARAMARK employees (n = 481) over the age of 18 were eligible to participate in the wellness program. Weekly 30 minute classes, taught by a Registered Dietitian, on various nutrition- and health-related topics were conducted for 10-weeks. Five question knowledge quizzes were administered to participants at the end of each class to determine the comprehension of material presented. Qualitative interviews (n = 19) were conducted with employees (participants and non-participants) and the program organizer after the completion of the 10-week program to identify barriers to program participation. A total of 50 (10.4% of the total number of potential participants) ECU ARAMARK employees, managers, and leadership team directors attended Wellness Wednesdays at least once during the 10-week program. Employees, on average, scored 71-100% on the weekly knowledge quizzes administered at the end of each class. The most common barriers to participation reported included (most often to least often reported): insufficient incentives, inconvenient locations, time limitations, not interested in topics presented, undefined reasons, schedule, marketing, health beliefs, and not interested in the program. Results showed that employee wellness programs can be effective in increasing knowledge of employees on nutrition- and health-related topics. However, program planning that addresses identified barriers including insufficient incentives, inconvenient locations, and time limitations may facilitate higher participation in future worksite wellness opportunities.

This study was conducted to investigate the health and nutritional status of 123 middle aged men at their worksite in Taejon. The results of this study on the factors that influence their health and nutritional status were as follows : 1) 74.8$\%$ of the subjects had history in the order of alimentary, heat, liver, diabetic and pulmonary diseases. 30.3$\%$ stopped smoking at 42.3% yrs. and 74.5$\%$ smoked more than 10 cigarets per day. Also 71.9$\%$ drank 2-3 times per week and 35.3$\%$ drank 1-2 times per week. 91.4$\%$ exercised more than 30min every day. 2) 54.4% showed concerns about their health whereas 20.3$\%$ were afraid that they night get sick. 3) 90.4$\%$ ate regularly and 54.5$\%$ worried about their cholesterol, salt, fat and MSG intakes. 48.7$\%$ ate out 1-2times per week and their favorite foods eaten outside were Korea. 4) 41.5$\%$ were classified as 'normal A', 30.9$\%$ 'normal B' group and high blood pressure and liber diseases in 'doubtful for disease' group were pointed out from their 1996 health check ups. 5) By Broca index, 39.8$\%$ were overweight and 9.8% were obese however by BMI only 23.6% were overweight. According to the relationship between calculated and self recognized obesity, 62.4$\%$ categorized themselves into the right weight range but 34.3$\%$ thought they were thinner than they were. 6) 43.9$\%$ were border line in cholesterol intake and 12.1$\%$ needed medical care for high blood cholesterol. 7) The Average energy intake was 1970.6㎉(80.9$\%$ RDA) with a 65 :19 : 16 ratio of carbohydrate : protein : fat. Protein, Fe, thiamin, riboflavin, niacin and Vit. A. 8) Occupation, regularity of meals, partner's job, income. smoking, alcohol drinking, health concerns and eating out were the factors that influenced the subject's nutrient intakes and health status. from this study, it was found that middle aged men needs to know their health and nutritional status and to be educated correct health and nutritional information through formal or informal channel. The worksite is the vest place to do this and we want these results to be used to develop the nutrition education program for middle aged men at the worksite.

The purpose of this study was to investigate the effect of 3-month nutrition education (First Time Intervention, FI) + additional 3-month nutrition education (Repeated Intervention, RI) which was performed after the 8-month followup. FI was conducted during 0-3 months and RI for 11-14 months. Ninety-two subjects completed FI program, and 38 out of 92 subjects who received FI finished the RI. Anthropometric data, dietary assessment (24hr recall) and fasting blood analysis were measured at 0 month, 3 months, 11 months and 14 months time points. After FI (3 mo), waist circumference, triglycerides, total cholesterol were significantly decreased. At 11 month follow-up, body weight, BMI, hip circumference, SBP, DBP were significantly rebounced and HDL cholesterol was significantly decreased. Therefore, the effect of short-term nutrition education was not being sustained. After the secondary nutrition intervention (14 mo), waist circumference and hip circumference were again significantly decreased. Total diet quality index-international (DQI-I) score was significantly increased in both FI group and RI group. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.129, p < 0.05) and counts of nutrition education (r = 0.159, p < 0.05), indicating that effective nutrition education helps improve the diet quality leading to a possible role in CVD prevention among male workers. Although a short-term intervention seems to be a success, the effect was not retained in this study. Therefore, we suggest incorporating nutrition education as a routine program for male worker at worksite.

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.
