This study examines the effects of smoking on the health and nutrient intake of male adults. The subjects recruited are divided into two groups according to non-smokers (n=64), and smokers (n=50). The results show that the non-smokers are significantly more interested in health and maintain more frequency of weekly exercise as compared to the smokers. Smokers reported that the main reason for failures in quitting attempts was a lack of willingness (62.0%). 44.0% of smoker would be interested in attending a smoking cessation program if they had the opportunities to do so. The non-smoker is considered healthy, and ate a regular diet, and low in fat-rich foods compared to the smokers. The non-smokers and smokers consume lower intakes of vitamin $B_2$, folic acid, and calcium (Ca). On the other hand, intakes of phosphorus, and sodium are the highest among all groups. In the case of smokers, increased intakes of antioxidant-rich fruits and vegetables should be encouraged, and the nutrition education for low-salt-type foods is also recommended.

The purpose of this study is to show that, before registration of chronic degenerative diseases and enforcing management system in health centers, the management of hypertension could achieved comprehensively and continuously by knowing the realities of drug-taking and its related factors those who are being cared for in health centers. For one year, a questionnaire about drug-taking realities of hypertensive patient was distributed at 8 health centers in Taegu from March 24. 1997 to April 24. 1997. The questionnaires were then collected and analysed. The results are as follows: Of 691 patients, 77.4% of patient were taking medicine regularly every day. The reasons why patients weren't taking medicine every day was as follows: the blood pressure became normal(34%, the highest of the group), patients forgot(28.2%), it was difficult to buy the medicine(15.4%), there was no effect even though the patient took medicine continuously. The experience of medical treatment outside of health centers was 28.9%. The types and percentages of alternative medicine are herbs (50.5%), health food(24.5%), folk remedy(13.7%). Among them, 44.6% of patients didn't know if the medicine was effective. Medical treatment places excluding health centers was pharmacies(63.5%-the highest rate). In simple analysis, the older one was the more regularly one took the medicine, but there was no statistical relations. Of health activities, patients eating low-salt diet showed that they took the medicine regularly. Nonsmoking patients and those who experienced drug side-effect and those who doubted doctor's prescriptions and instructions showed that they took alternative, excluding modem medicine. Anti-hypertensive drug medication status according to recognition, attitude, experiences of hypertension showed that patients who thought that they should take anti-hypertensive drug during the whole life time took the medicine regularly(82.3%). The reasons for patients turning to alternatives varied. In case of having subjective symptom(34.1%), those who thought they knew the hypertension well(36.6%), they decided to use alternatives. In multiple logistic regression analysis the key statistics were as follows: The older patients, patients who ate low-salt diet, patients who thought that they should take anti-hypertensive drug during the whole life time, all showed that they took medicines regularly. And also patients who experienced drug side-effect, doubted prescriptions and instructions, and patients who had subjective symptoms, patients who thought that he knew the hypertension very well, all showed higher rate of using alternative medicine. In the future, at the health centers, to register and manage hypertension patients effectively, we must educate patients about regular drug-taking, and alternatives without doctor's prescriptions.

This study was performed to investigate the change in taste perception during aging and its effects on dietary intake in Korean elderly. The subjects were female aged 65 through 90 in the Anyang area, and college women were included as a comparison group . Dietary intake of the elderly(n=155) and young subjects (n=38) was measured by a 3 day diet record. The taste threshold and 'just right' concentrations(JRC) for sweet and salty tastes were assessed by sensory evaluation . Sucrose solution (0.0.,0.4,0.6,0.8,1.0, 1.2%) and salt solution(0, 0.02, 0.03,0.06,0.09,0.12,0.15%) were used to establish thresholds. for JRC assessment, four suprathreshold sucrose concentrations of 5, 8, 11 and 14% in orange-pineapple flavored juice and salt concentrations of 0.20, 0.34, 0.50and 0.75% in beef stock were prepared. Mean intakes of energy, protein , vitamin A, thiamin , riboflavin, niacin ,calcium and iron of the elderly were below the Korean Recommended Dietary allowances. The elderly showed higher taste thresholds than young subjects of both sweet and salty tastes consumed less calories. Needs to bespecified. The older subjects having high threshold or JRCs for sweet and salty tastes consumed fewer calories from protein and fat. Pearson correlation coefficients was between JRC for sweet and salty tastes 0.54(p<0.01). The correlation coefficients between tastes threshold and nutrient intakes were very low for both age groups. Unlike the college women, in the elderly the JRC of sweet taste of the orange-pineapple juice were negatively correlated with intakes of energy, protein, fats, thiamin , riboflavin , niacin ,vitamin C , iron and consumption of meat and egg food groups (p<0.01). In summation age-related alterations in sweet and salty taste perception were observed in the elderly and dietary intakes of the elderly see to be influenced by these taste perception changes.

This study was aimed for examining the changes of eating habit and behavior according to the degree of stress of elementary school students. It was tried to identify their daily stress levels and their relevances with the changes of their eating habits and behaviosr. The subjects were 500 students from fifth and sixth grades in three elementary schools in Seoul. The students surveyed showed to get moderately stressed in general. The stress level of girls were higher than that of boys(p<0.001) in the individual area. The breakfast ratio of the low stressed group(LS) marked higher(p<0.001) than those of both the middle-(MS) and highly-stressed group(HS). In other words, the LS group had regular breakfast. The main reason why they were skipping breakfast was lack of time. The amount of a meal in the HS group was noticeably bigger than the other two groups(p<0.05) and the amount of salt and spices used was higher(p<0.01). The amount of food taken when they got stressed was increased remarkably higher in the HS group and students in that group had snacks as the way of relieving the stress. The HS group displayed higher ratio of the unbalanced diet habit. There were noticeable differences in the eating habit and behavior, i.e. the amount of meals, of salt used and whether eating breakfast or not, in accordance of the levels of stress.

Objective: To examine the effects of sodium intake on the correlations between the saltsensitive gene ${\alpha}$-adducin 1 (ADD1) and inflammatory cytokines in Korean childhood obesity. Methods: A total of 2,070 students aged 8-9 years old participated in this study. The anthropometrics, serum biochemistry profile, inflammatory cytokines, and three-day dietary assessment were analyzed according to sex, obesity degree, and ADD1 polymorphism. Results: The obesity prevalence was higher in boys (15.6%) than in girls (11.9%). Boys also showed higher values in anthropometrics; lipid, glucose, and insulin profiles; total calorie intakes, as well as those of sodium and calcium compared with those of the girls. The more obese were boys and girls, the higher were the anthropometrics and the blood levels (total cholesterol, triglyceride, low-density lipoprotein cholesterol, fasting blood sugar, and insulin), but the lower was high-density lipoprotein cholesterol. The obese boys had significantly higher sodium and Na/K intakes, while the obese girls had higher visfatin level and Na/K intake. In addition, an increase in the risk factors for blood pressure and obesity in ADD1 variants was identified. Serum tumor necrosis $factor-{\alpha}$($TNF-{\alpha}$) significantly increased with increasing sodium intake in the ADD1 W allele carriers, regardless of sex. The presence of obesity with the ADD1 W allele induced inflammatory accelerators such as $TNF-{\alpha}$ or C-reactive protein(CRP) with higher sodium intake. Conclusion: Obese children with an ADD1w allele can experience a more complex form of obesity than non-obese when exposed to an obesity-inducing environment and need to be controlled sodium intake in the diet.

The risks of the metabolic syndrome (MS) is known to be related to the dietary behavior. The objective of this study is to evaluate the association between the relative risks of MS and the dietary habit and to provide the ideal dietary habits for prevention of chronic disease of the middle-aged. Healthy subjects aged 40-64 years (male n=122, female n=173) were recruited throughout Seoul area. MS was defined according to NCEP-ATP III criteria except central obesity, and Asia-Pacific Area criteria for central obesity (2000) was adapted. Subjects were stratified into 3 groups according to the number of total risk factors:'MS group' was defined as the subjects who have three or more risk factors, 'Risk group' was defined as ones to have one or two risk factors, and 'Healthy group' defined as ones with no risk factor. In this study, 'Health group' comprised of $40.7\%$, the percentage of 'Risk group' was $49.0\%$, and the 'MS group' was $9.5\%$ of the total subjects. The MS incidence was associated with low education (p<0.001), low economic status (p<0.05), and low self-assessed health recognition (p<0.05). The risk of MS increased with adverse life styles such as cigarette smoking (p<0.05), irregular meal time (p<0.05), skipping lunch (p<0.05), low interests in balanced diet (p<0.05), and higher salt intake (p<0.01). Healthy group self-evaluated nutritional knowledge more highly (p<0.05) and scored higher nutritional knowledge (p<0.001). However, there was no difference in overall nutritional behavior among the three groups, which implies that nutritional education method should be developed for the subjects to practice their teaming efficiently.

Responses of atrial natriuretic peptide (ANP), aldosterone and renin release to acute volume expansion were compared in normotensive Wistar and spontaneously hypertensive rat (SHR) fed low or high-sodium diet (2 or 25 mmol Na/100 g diet). Experimental diets were fed for 6 weeks from 7-week-old and the growth rate was similar in all groups. In the morning of the experiment, catheters were inserted under ether anesthesia in femoral artery for pressure recording and blood collection, femoral vein for saline infusion, and bladder for urine collection. Then, the rats were placed in restraining cages. When the rats were recovered from anesthesia and the arterial pressure became stabilized, control urine and blood samples were collected. Then, 0.9% saline was infused for 30 min for volume expansion (3% BW). Arterial pressure was significantly higher in the high-sodium SHR but there was no difference between the two groups of Wistar rats. Control plasma levels of Na, K, ANP, renin activity, and hematocrit were not different among the 4 groups. However, plasma aldosterone level was significantly higher in the low-sodium groups. Wistar low-sodium rats showed approximately two times higher plasma aldosterone level than the SHR counterpart. Volume expansion produced a marked increase in plasma ANP level, especially in the high-sodium groups. The low-sodium groups of both strains showed approximately two-fold increase in plasma ANP level. Following a volume expansion plasma aldosterone level and renin activity decreased in all groups. There was a significant logarithmic positive correlation between plasma renin activity and aldosterone concentration. The low-sodium rats produced a greater increase in aldosterone release by small increase in plasma renin than did the high-sodium rats. The low- and high-sodium rats produced a similar degree of diuresis and natriuresis after volume expansion. However, SHR produced a greater natriuresis than did the Wistar rats. The above results indicate that regulatory mechanisms of ANP, aldosterone and renin release are different between the normotensive and hypertensive rats, and between the low- and high-sodium groups.

Rapid economic development has changed the dietary habits and patterns. Especially, western style diet has increased the risk of type 2 diabetes (T2DM) in Korea. To provide more specific and appropriate diet guideline for the prevention and for the treatment of T2DM, the investigation on the characteristics of diebetic patients related to the diet needs to be done. In this study, we therefore analyzed eating behaviors, dietary attitudes, and intake of food and nutrients of normal subjects (control, n=26) and diabetic patients (case, n=18) diagnosed T2DM within one year in Daegu Gyeongbuk area. Body mass index of the patients were significantly higher than the control (p<0.05). Overeating, high fried food and low whole grain intake were revealed as risk factors for T2DM. From the food frequency questionnaire analysis, salty foods such as fermented soybean paste (Doenjang) and watery Kimch intake were associated with T2DM. Intake of vegetable lipid, ${\beta}$-carotene, calcium, copper, and vitamin K were also shown to be associated with T2DM. Taken together, these findings suggest that maintaining ideal body weight and intake the foods with low salt, fat, and refined grain in appropriate amount may help to prevent and to manage T2DM.

The purpose of this study was to investigate dietary behaviors and health-related lifestyles of adult visitors at a public health center in Gyeonggi urban area. A survey using questionnaire was conducted with 949 visitors at Seongnam public health centers from June to August, 2012. The data from 905 respondents were analyzed by gender, consisting of 322 males and 583 females, and age group, consisting of 243 low-age group (LA), 312 middle-age group (MA), 350 high-age group (HA), aged 20 to 30 years, 31 to 50 years, and 51 to 69 years, respectively. Average Body Mass Index was 23.0, which increased with age, and education level was high in LA. 59.0 percent of the subjects had various diseases, and the incidence of hypertension was the highest, followed by allergy, hyperlipidemia, diabetes mellitus, joint rheumatism. Incidence rates of chronic disease increased with age, which were lower than those from 2011 Korea National Health and Nutrition Examination Survey (KNHANES). Weekly drinking frequency rate and smoking rate decreased with age, and exercise performing rate was high at male and HA, which showed the same tendency as KNHANES. Female and HA showed more healthy dietary behaviors such as restricting salt, sugar, oily foods, foods containing food additives, calorie, caring for balanced diet, and referring to nutrition label. Subjects chose stress as the first factor, followed by diet, exercise, etc., among 13 suggested factors which strongly influence on human's life-span. In general, public health center visitors, especially female and HA, showed better dietary behaviors and health-related lifestyles compared with KNHANES.

BACKGROUND/OBJECTIVES: This study evaluated whether a mobile health (mHealth) application can instigate healthy behavioral changes and improvements in metabolic disorders in individuals with metabolic abnormalities. SUBJECTS/METHODS: Participants were divided into an mHealth intervention group (IG), which used a mobile app for 24 weeks, and a conventional IG. All mobile apps featured activity monitors, with blood pressure and glucose monitors, and body-composition measuring devices. The two groups were compared after 24 weeks in terms of health-behavior practice rate and changes in the proportion of people with health risks, and health behaviors performed by the IG that contributed to reductions in more than one health risk factor were analyzed using multiple logistic regression. RESULTS: Preference for low-sodium diet, reading nutritional facts, having breakfast, and performing moderate physical activity significantly increased in the mHealth IG. Furthermore, the mHealth IG showed a significant increase of eight items in the mini-dietary assessment; particularly, the items "I eat at least two types of vegetables of various colors at every meal" and "I consume dairies, such as milk, yogurt, and cheese, every day." The proportion of people with health risks, with the exception of fasting glucose, significantly decreased in the mHealth IG, while only the proportion of people with at-risk triglycerides and waist circumference of females significantly decreased in the control group. Finally, compared to those who did not show improvements of health risks, those who showed improvements of health risks in the mHealth IG had an odds ratio of 1.61 for moderate to vigorous physical activity, 1.65 for "I do not add more salt or soy sauce in my food," and 1.77 for "I remove fat in my meat before eating." CONCLUSIONS: The findings suggest that the additional use of a community-based mHealth service through a mobile application is effective for improving health behaviors and lowering metabolic risks in Koreans.
