This study was performed to assess socioeconomic status and physical health status of middle-aged men ($40's{\sim}60's$) in Ganghwa country. We interviewed 1,267 middle-aged men (602 male, 665 female) by trained interviewers using structured questionnaires including demographic information, general health status, and anthro-pometric measurements. And all the data were analyzed by chi-square test, Student's t-test and one-way ANOVA using SPSS 12.0 version at p<0.05. These results were that males were higher than females in educational levels (p = 0.000) and most of them decreased according to age in educational levels (p =0.000) and family income (p =0.000), and prevalence of chronic diseases (p =0.000): stomach-duodenum disease, fracture, arthritis, or hypertension. They took to the health information on TV and radio and their health managing methods were exercise and walking and resting and diet regulation. Body Mass Index (BMI) was decreased in oder males (p =0.024) but increased in older females (p=0.001). In females, obesity prevalence of 40's, 50's and 60's was 31.3%. 49.7% and 48.0%, respectively. Waist circumference was the highest in 50's males (p=0.015), but hip circumference was the highest in 50's females (p =0.015). Waist-hip ratio (WHR) increased in older males (p = 0.028) and females (p= 0.000). In spite of the subjects were engaged in agriculture and fishery and had desirable lifestyles obesity rate especially abdominal obesity, was the serious problem. Socioeconomic status, especially education and income were related to SRH (p=0.006, p=0.000), chronic disease (p=0.000) and BMI (p=0.028, p=0.000). Therefore, it is necessary that the public health policy and nutrition education programs to alter lifestyles and to improve health preservation and health promotion in the farming and fishing communities.

The purpose of this study was to evaluate changes of body composition, cardio-respiratory function in ventilation threshold (VT) and maximal state exercise, systolic (SBP) and diastolic blood pressure (DBP) and serum nitric oxide (NO) production during acute reducing salt (RS) supplementation in college elite athletes. Variables of cardio-respiratory function during rest, ventilation threshold and maximal exercise was not shown a significantly difference between RS supplementation and non-supplementation, there was shown a significant increase in ventilation threshold time (p<0.05) and exhaustion time (p<0.05) during RS supplement compared to non-supplement. SBP and DBP were not shown a significant difference between RS supplement and non-supplement. This result suggests that acute intake of RS is not increased a blood pressure. Serum NO production was not significant difference in the RS supplement group, but it was shown a significantly increased levels (p<0.01, vs. recovery 30 min.) immediately after maximal exercise in the non-supplement group. This result suggests that acute intake of RS have important role in inhibition of serum NO production during maximal exercise. Conclusively, This study suggest that acute intake of RS was not influence in body composition variables, but it was positive effect in ventilation threshold time, exhaustion time, maintenance of blood pressure and inhibition of serum NO production in maximal treadmill exercise.

Objectives: It has been well documented that people on the lower socioeconomic position are significantly more likely to smoke cigarettes. The purposes of this study were (a) to identify a potential difference of socioeconomic factors, and (b) to compare a smoking rate, one of the most representative health behavior between people with/without disabilities after the controlling socioeconomic factors. Methods: The Korea Panel Survey of Employment for People of Disabilities (2012) and the Korea National Health and Nutrition Survey (2012) were employed for calculating the smoking rates of persons with/without disabilities. Results: The results demonstrated that the socioeconomic position indicators (education, occupation and household equivalent income) of persons with disabilities were lower than persons without disabilities. The smoking rates of the persons with/without disabilities were 35.9% and 19.0% respectively before propensity score matching. After propensity score matching with the socioeconomic factors, however, ATT of people with disabilities was 0.201 which is lower than ATT of people without disabilities (0.227). Conclusions: Our findings indicated that the socioeconomic level of persons with disabilities is important to improve the smoking rates and health level regardless of their disabilities.

Foodservice management practices in 52 educare centers in Jeonbuk province were evaluated in order to provide basic informations and guidelines for the standardization of foodservice management and facilities in the educare centers. The survey was conducted using the structured questionnaire. The results are summarized as follows: 1. Only 10% of the centers investigated had the stationed dietitian, therefore most of foodservice management was not conducted by a professional personnel. The average number of kitchen employees was 1.3 and significantly different with type(p<0.05) and size(p<0.001) of the centers, which was not enough to meet the regulation. 2. Menu planning was performed mostly(59.6%) by managers and teachers of educare centers. Food items were purchased(94.7%) and recieved(91.6%) by kitchen employees or center managers and teachers. Produced foods were also evaluated(97.7%) and distributed(100%) by kitchen employees or center managers and teachers depending on their experience without any supervision of the professional personnel for the mass production. 3. Among the centers studied, 84.6% of them conducted nutrition education programs regularly by teachers. About 77.3% of them evaluated that these programs did not accomplish the proper training for good food habit because of the lack of nutritional knowledge(54.5%) and educational media(27.3%). 4. In general, the hygienic maintenance was evaluated as fair state to need the improvement. 5. Kitchen facilities and equipments were similar to those of home cooking and did not meet the standards for institutional practices. Besides, automated machinery and tools for safety, sanitation and improvement of work efficiency were far short. 6. Log book for the foodservice management was not prepared properly, which made the systematic planning and operation of the foodservice facilities difficult.

Endocrine-disrupting chemicals (EDCs) are chemicals present in the environment that interfere with the normal hormone functions of various organisms and cause genetopathy, deformities, or cancer. This study surveyed the awareness of EDCs with 242 cooking staff at 242 meal service facilities for children located in a part of Gyeonggi Province. To minimize infants' exposure to EDCs, the subjects were provided with information on EDCs for two months. The behavior of reducing exposure to EDCs was analyzed according to the awareness of EDCs and work ethics. In addition, the effects before and after being provided with the information were evaluated. According to the results, the levels of awareness of EDCs and work ethics' scores of the cooking staff were high with 3.95 and 4.39 points, respectively, out of five points. In addition, a higher awareness of EDCs and a higher work ethics' score were associated with an improved behavior of reducing exposure to EDCs (P<0.05). The overall cooking and cleaning behavior for reducing exposure to EDCs showed improvement after providing information (P<0.01). Therefore, these results suggest that it is important to provide continuous education to enhance the awareness of EDCs, work ethics, and behavior to reduce exposure to EDCs.

BACKGROUND/OBJECTIVES: Although some juices affect subjective sleep quality, there is a lack of information on the effect of a specific juice on objective sleep quality and heart rate variability (HRV) during sleep; thus the present study investigated whether a blended juice made from natural extracts influenced sleep quality and HRV during sleep in adults with disturbed sleep. SUBJECTS/METHODS: A randomized, crossover study was conducted on twenty-five adults (15/10, female/male) complaining of difficulty initiating or maintaining nighttime sleep (Pittsburgh sleep quality index [PSQI] ≥ 5). During feeding sessions (FS), subjects received sleep-inducing juice made of natural ingredients (250 mL/trial) twice a day for 8 weeks or non-FS (N-FS) for 8 weeks while maintaining normal activities. Sleep quality and parameters were recorded via wearable actigraph for 7 consecutive days, and PSQI scores were assessed before and after the intervention. HRV was also monitored at rest and during sleep. RESULTS: After receiving the sleep-inducing juice intervention (FS), PSQI scores were significantly decreased (P < 0.001) and correlated with a significant decline in fatigue severity scale and visual analogue scale levels (P < 0.05; both). HRV indices of vagal activity were significantly improved during FS (P < 0.05), and no significant differences in N-FS were observed. Sleep efficiency and total sleep time increased significantly (P < 0.05) and sleep latency, total counts, sleep fragmentation index, and movement index, decreased significantly (P < 0.05, all 4) during FS, with no significant differences-observed during N-FS. CONCLUSIONS: This study results demonstrated that an 8-week course of sleep-inducing juice has led to improve sleep quality, suggesting an enhanced cardiac vagal tone during sleep. Thus, it could be a well-tolerated option for adults with disturbed sleep.
