To investigate the status of farmers health management for health promotion, and for checking the effect of village health care center during 1 year, 746 subjects were selected with cluster method in 8 provinces of Korea. The most frequent group was 40th of age (39%) : elementary school graduates (32%) The self-conscious of health status tested with CMI (Cornell Medical Index) questionnaire, the subjects in the village of health care center had lower health status than those of conventional village. The farmers living in the village with health care center had longer agricultural work (p<0.05) and more frequency of spraying pesticides in the fields. The subjects of living the village of health care center were frequently exercise (34%) with health appliance use methods (30%), but the duration time of exercise was similar, Dietary habits and agricultural work condition were similar between two groups. For the fatigue recovery, steeping and bathing were most favorite methods, but exercise was lowest. It was significantly different between 2 groups the fatigue recovering methods, the subjects of village with health care center were more doing exercise (p<0.01), less sleeping (p<0.01) than those of conventional village. The working condition of self-estimated of farmers was not good, only 8.7% was thought pleasant condition. Of the various health factors, exercise, nutrition, and working situation would be more important. Considering on farmers exercise, it was very weak point for health management. The foundation and leading of the Farmers health care center was encouraged to farmers. For more effective operations, the experts education, easy and funny exercise program, and health promotion committee for administrators would be needed. The better systemic and continuous exercise programs should develop for associating livelihood. Funding for this project provided by the ministry of health and welfare of Korea.
It is necessary to understand the relationship between socio-cultural elements and smoking, alcohol, and marijuana use behaviors in order to plan public health policy or health promotion program of Mexican Americans. Demographic, socioeconomic status, and acculturation are variables which reflect mechanisms socialization influences these behavior patterns among this population. Thus, this study investigates the prevalence of addictive behaviors and individual differences on addictive behaviors related to variables of acculturation, age, gender, education, and income. And the interrelations among addictive behaviors are also examined. The analyses used data for Mexican Americans from the U.S. Hispanic Health and Nutrition Examination Survey conducted from July 1982 through December 1984 by the National Center for Health Statistics. ANOVA and correlation coefficients were used for this study. This study found that there are gender differences among addictive behaviors in their prevalence. Both males' and females' alcohol and marijuana use behaviors are positively related to the acculturation. Females' smoking behavior is positively related to acculturation while males' smoking is negatively related to it. Income and education are negatively related to males' smoking and positively related to males' alcohol behavior. However, males' marijuana behavior is not related to income. Females' smoking behaviors is not significantly related income and education. Education and income are positively related to marijuana behavior among females. Age is related to all three addictive behaviors among both gender. Age is negatively related to both males' and females' marijuana use behavior. Interrelation between smoking and marijuana use behavior is not significant among males. However, interrelations between alcohol and marijuana use behavior and between alcohol and smoking are significant among both genders. Females' smoking and marijuana use behavior is also significantly related.
[Purpose] The purpose of this study was to investigate the effects of short-term creatine intake on muscle fatigue induced by resistance exercise in healthy adolescent men, i.e., lactic acid concentration and wrist and head tremor measured by an accelerometer. [Methods] Twelve healthy adolescent men who had no experience with creatine intake were included. The subjects were randomly assigned to the creatine group and the placebo group, followed by 5 days of creatine and placebo intake, and 5 times of 5 sets of leg press, leg extension, bench press, and arm curl exercises at 70% repetition maximum (RM). The lactic acid concentration before and after exercising, rate of perceived exertion (RPE), and accelerometer-based wrist tremor and head tremor during exercise were measured. Subsequently, after 7 days to allow for creatine washout, the same exercise treatment and measurement were performed in each group after switching drug and placebo between the groups. [Results] The level of lactic acid before and after the acute resistance exercise trial was significantly lower in the creatine group than in the placebo group (P <0.05). The mean RPE during the resistance exercise was significantly lower in the creatine group than in the placebo group (P <0.05). There was no difference between the two groups in the mean wrist tremor during resistance exercise, but the mean head tremor values were significantly lower in the creatine group than in the placebo group in the arm curl, the last event of the exercise trials (P <0.05). [Conclusion] Short-term creatine intake reduces the blood fatigue factor increased by resistance exercise, and is thought to suppress fatigue, especially in the latter half of resistance exercise. Therefore, these findings indicate that short-term creatine intake can have an improved effect on anaerobic exercise performance.
Age-related changes in bone metabolism are well established by biochemical markers of bone matrix in serum and urine, but analysis of the residual bone matrix, which is still turning over, has not been investigated. In the present study, we measured in vivo rates of bone protein synthesis using a precursor-product method based on the exchange of ²H from ²H₂O into amino acids. Four percent ²H₂O was administered to mice in drinking water after intraperitonial (i.p) bolus injection of 99.9% ²H₂O. Mice were divided into the two groups: growing young mice were administered 4% ²H₂O for 12 weeks after an i.p bolus injection at 5 week of age, whereas weight stable adult mice started drinking 4% ²H₂O 8 weeks later than the growing group and continued 4% ²H₂O drinking for 8 weeks. Mass isotopomer abundance in alanine from bone protein was analyzed by gas chromatography/mass spectrometry. Body ²H₂O enrichments were in the range of 1.88-2.41% over the labeling period. The fractional synthesis rates (ks) of bone protein were 2.000±0.071%/d for growing mice and 0.243±0.014%/d for adult mice. These results demonstrate that the bone protein synthesis rate decreases with age and present direct evidence of age-related changes in bone protein synthesis.
The objective of this study was to evaluate associations between airborne manganese and blood manganese in a general population of South Korean adults. The concentrations of airborne manganese in total suspended particulate (TSP) were calculated from data obtained from ambient air-monitoring stations (AAMSs) located in South Korea. Blood manganese data obtained Korean National Health and Nutrition Examination Survey (KNHANES) using a rolling sampling design involving a complex, stratified, multistage, probability cluster survey of a representative sample of the non-institutionalized civilian population of South Korea. Airborne manganese geometric means was 46.10 $ng/m^3$, blood manganese geometric means were 1.19 ${\mu}g/d{\ell}$ for male and 1.40 ${\mu}g/d{\ell}$ for female. In multiple linear regression analysis of log transformed blood manganeseas a continuous variable on airborne manganese, after adjusting for covariates including gender, age, job, smoking and drinking status, education level, BMI (body mass index). Airborne manganese was positively associated with blood manganese with statistical significance. The present study confirms that airborne manganese is a possible contributor to the increase of blood manganese in the adult general population.
The purpose of this study was to evaluate weight control program provided by university health care center for female college students. The program was 8-week long and composed of diet, exercise, and behavioral modification. Evaluation was made on the completion of 8-week program and a follow-up survey was done at 3-24 months after the end of program by telephone or bye-mail. Total of 76 women completed the 8-week program and 51 for follow-up survey. On the completion of 8-week program, significant decreases in body weight, BMI, body fat (kg), % body fat, and WHR were resulted, however, no change in muscle mass was found. Even the subjects without weight change showed significant reduction in body fat (kg) and % body fat. Total food intake was decreased resulting in reduced intakes of most nutrients. Meal distribution of energy was changed; %energy from snack decreased from 22% to 14%, and proportion for breakfast increased. Blood values of hemoglobin, hematocrit, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride were within normal range, and no changes were observed by this program. The follow-up survey revealed that 88.3% of the subjects continued to lose weight after completion of the program, while only 7.8% gained weight. And 78.4% of the subjects considered the program effective. In conclusion, the weight reducing regime with education is effective for long lasting weight control and health conscious behavior for female college student. Since the subjects reduced the size of meal, instead of cutting only calories down, food selection to meet all the nutrient requirements except energy should be emphasized.
This study was performed to investigate the effect of family type on the nutrient intake and nutritional status in elderly women. Blood samples and anthropometric data of elderly women aged from 60 to 78 years were collected in 1996, who visited a health examination center in Seoul to screen their health status. They were divided into two groups by their family type, one was extended family(extended family elderly, n=37) and the other was independently living(independently living, n=29). Nutrients intake was measured by interview using a simplified questionaire. Albumin, cholesterol, triglyceride(TG), hemoglobin (Hb), hematocrit, Ca, Mg, and alkaline phosphatase activity of serum were analyzed. Intakes of energy, protein, carbohydrate, Fe, vitamin A, niacin, thiamin, riboflavin, and vitamin C were not different between the two groups. However, fat and Ca intakes were higher(p<0.05) in extended family elderly than indepen dently living elderly. There are no significant difference in hematocrit value and serum concentrations of Hb, TG, and Ca. Serum Mg and cholesterol levels tended to be higher in extended family elderly. However, serum albumin level was lower(p<0.05) in extended family elderly. These results show that the indepen dently living elderly women had intakes of daily energy, fat and Ca compared to the extended family elderly. Therefore, the nutritional education for the independently living elderly will be focused on the health risk resulted from less intakes of Ca and total energy.
Background: This study investigated the hearing status in Korean adults according to data from the Korea National Health and Nutrition Examination Survey 2009. Methods: The data of 3,479 adults(${\geq}20$ years, 1,492 men, 1,987 women) collected by the Korean Center for Disease Control was analyzed using ${\chi}^2$-test and logistic regression. Results: Differences in hearing loss according to individual factors were evident by follows gender, region, education status, economic status, current smoking and recognition of stress. Differences in - hearing loss according to ear related factors were evident subjective hearing status, experience of tinnitus, prevalence of chronic otitis media, and tympanomembrane abnormality. Conclusion: Hearing-related disorders can cause many social problems. This study investigated a representative cross-section of Koreans to determine the hearing status. The study was limited in that the risk factors of hearing loss were not identified. It is also recommended that a program be developed that can help control the variables identified in this study along with follow-up studies to verify the model.
This study evaluated the evaluate nutrient knowledge of child care teachers and assessed the nutritional level of snacks served in 18 child care centers in Tean-Gun. The survey sample was 18 child care teachers working in 18 child care centers of Tean-Gun. The questionnaire requested information about demographic factors, nutritional knowledge, management status of snacks, and the kinds and serving size of snacks served for 1 week. Data were analyzed using SPSS for windows(version 12.0) and nutritional values were assessed using Can-pro 2.0. The mean score of teachers' nutritional knowledge was 22 out of 30 points. The scores were low in the questions regarding the ease with which Ca and re deficiencies can be developed in infants. The contents of most nutrients supplied from the snacks exceeded 15% of RI(Recommended Intake) but there were significant differences in the contents of energy (p<0.05), protein (p<0.05), fat (p<0.05), carbohydrate (p<0.05) and calcium (p<0.001) between the child care centers. Especially, the difference of calcium between the child care centers was 344.84 mg. These results indicate that a program of relevant nutritional education focusing on snacks needs to be developed for child care teachers, with a special recognition on correct calcium level.
Objectives: Stress is the cause of several illnesses, in older people, stress may also cause various social problems. The oral health of older adults is closely related to the quality of life, and chewing ability is particularly important for their general health. The purpose of this study was to investigate the relationship between stress, the number of teeth remaining, and the chewing ability, which reflects the oral health status among older adults. Methods: This study evaluated the stress level and chewing ability of adults older than 65 years using the 6th (2014-2015) Korea National Health and Nutrition Examination data. The total number of remaining teeth was determined based on the data of the teeth conditions. Results: There was an association between stress and chewing ability among older adults. The odds ratio of chewing function increased by 2.67 times (crude OR=2.67; 95% CI=1.88-3.79) with increased stress. After adjusting, the odds ratio increased to 2.74 times (adjusted OR=2.74; 95% CI=1.88-3.98). Conclusions: Reducing stress may facilitate effective oral health management and improve the overall quality of life in older adults. The findings of this study may help in the discovery of various approaches s to reducing stress in older adults and provide relevant information for oral health education.
