This study presents the status on drug prescription for clinic outpatients' bronchitis, gastritis, and gastric ulcer, and also the physician factors that affects their prescriptions. In this research project the physician factors are as follows: their demographic features, their work related features, education related features, drug information related features and drug promotion related features. The variables in drug prescriptions are drug expenses, daily drug expenses, days of medication, the highest price of the drugs used and the number of the different drugs used. Analysis of the use of prescription drugs was performed on NFMI(National Federation of Medical Insurance) 1994 medical expense claim data. Data on physicians' characteristics were collected by mailing surveys. Patients with secondary diseases were excluded. In this study, 388 adults with bronchitis, 1,038 children with bronchitis, 1,158 patients with gastritis, 369 patients with gastric ulcer were included. The older physicians tend to allow the lower drug costs: this explains that the older doctors who are more experienced less depend on the medicines. It can be also explained that doctors are likely to use the medicines that had been used for their intern and resident practice/training period. General practitioners give more intensive prescription compared to specialists. And specialists prescribed medicines to patients for longer period. The doctors' prescriptions for patients are largely affected by commercial sources. So objective and reliable sources for drug information is needed for patients' benefits. Physician factors explain better at the daily drug expenses, the drug price and the number of different drugs than days of medication. Gastric ulcer are better explained by the prescription model adopted in this study than other diseases.

Objectives: The purpose of this study was to examine the cross-sectional relationship between low blood lead levels and increasing blood pressure among Korean adults using a nationally representative sample of the Korean population: the Korea National Health and Nutrition Examination Survey (KNHANES) 2008. Methods: A total of 918 subjects aged 40 and older and not currently being treated for hypertension participated in this study. Information about age, gender, smoking status, alcohol consumption, education level, and the use of anti-hypertensive medication was collected. The blood pressure was defined as the mean of the second and the third measurements after three time measurements. Lead levels were determined by an analysis of blood samples. Multiple linear and logistic regression analyses were implemented after adjusting for covariates including age, gender, educational level, smoking status, alcohol consumption, and BMI. Results: This study showed that the average differences in systolic and diastolic blood pressure comparing the lowest to highest quintile of blood lead were 4.33 mmHg (95% CI, 0.66-8.00; p for trend = 0.027) and 2.66 mmHg (95% CI, 0.26-5.06; p for trend = 0.021), respectively. After multivariate adjustment for covariates, the prevalence odds ratio (POR) of subjects in the highest quintile was associated with a 1.70-fold increase in the risks of hypertension (95% CI, 0.83-3.49; p for trend test = 0.112) over those in the lowest quintile of blood lead concentration, However, it was not statistically significant. Conclusions: This study provided evidence for an association between low- levels of blood lead and elevations in blood pressure and risk for hypertension in the general population of Korea.

In this study, PASW Statistics ver. 18.0 was used to analyze the correlation between chewing difficulty and osteoarthritis in the population of 8,498 persons aged 50 years and older who had completed the health related questionnaire in the fifth Korea National Health and Nutrition Examination Survey in 2010~2012. The following conclusion was drawn: The distribution of the chewing difficulty status showed that 38.8% of the respondents had chewing difficulty and that there was no significant difference by gender. Older respondents tended to have significantly greater chewing difficulty 34.3% of the respondents aged from 50 to 64 years and 46.4% of those aged 65 years and older, those who had lower levels of education and income, who were smokers, and who had higher levels of depression and stress suffered from significantly greater chewing difficulty. Chewing difficulty and osteoarthritis were correlated with each other: the respondents having chewing difficulty had 1.44 (95% confidence interval [CI], 1.23~1.70) higher prevalence of osteoarthritis than those with no such difficulty. In addition, such correlation was not found in males: the former had 1.36 (95% CI, 0.98~1.88) higher prevalence of osteoarthritis than the latter, which was not statistically significant. Such correlation was found in females: the former had 1.47 (95% CI, 1.22~1.76) higher prevalence of osteoarthritis than the latter, which was statistically significant. Therefore, the chewing difficulty status affected osteoarthritis for females aged 50 years and older. Therefore, the efforts to solve oral health problems through oral hygiene would help prevent osteoarthritis from worsening and manage the condition.

The purpose of this study was to analyze the dietary habits and food intake by age, based on the nutrition counseling data of medical health examination. The subjects were 5,511 adults(3,139 males and 2,372 females) who took comprehensive medical test in Gyeonggi area, and they were evaluated from January 1, 2007 to December 31, 2007. Survey samples were divided by age groups : 30>, 30~39, 40~49, 50~59, 60~69, 70{$\leq}$ years. The subjects were composed of 57% male and 43% female. The results showed that the dietary habits of ${\geq}$50 group were relatively good. On the other hand, in 30> yrs group had more dietary habit problems, they had irregular meals and the ratio of skipping breakfast was high. And they frequently had meals out. regularity of meals, eating breakfast was higher in ${\geq}$70 yrs groups than in other groups(p<0.001). frequency of overeating was higher in 30>, 30~39${\geq}$yrs groups than in other groups(p<0.001) and speed of eating meal were fast in 50~59 yrs groups than in other groups(p<0.01). For foods with high cholesterol and fat, it was shown that the older the subject, the fewer the frequency of consumption(p<0.001). For kimchi and salty foods, food intake showed a negative relationship with age(p<0.001), whereas for fresh vegetables and high-calcium fish, it showed a positive relationship(p<0.001). All in all, it was shown that as the people get older, their dietary habits tend to get more appropriate. In conclusion nutrition education based on their dietary habit by age should be taught, so that people have a healthy dietary habit and food intake for the rest of their life.

[Purpose] We aimed to identify the effects of marine oligomeric polyphenol (MOP) intake in elderly individuals with sarcopenia. [Methods] Older adults (aged 65 years or older) were recruited based on the diagnostic criterion for sarcopenia and were randomly assigned to the MOP intake group (n=10) or the placebo (PBO) intake group (n=10). To determine the effect of MOP intake received for four weeks, the pre- and post-intake body composition (weight, skeletal muscle mass, and bone density) and senior fitness tests were assessed. [Results] Our results showed there were significant differences in the skeletal muscle mass (p=0.039), bone density (p=0.020), fat-free mass index (p=0.026), and 2.4 m up and go test (p=0.001) between pretest and post-test. There was a significant difference between the pre-test and post-test and an interaction effect for the one-leg stand test (p=0.010 and p=0.049, respectively). However, there were no significant differences in body fat percentage, calf circumference, grip strength, or the chair rise test. [Conclusion] Some variables exhibited significant differences in the pre- and post-assessments, and there was an interaction effect for the one-leg stand. However, this was insufficient to prove the effectiveness of MOP intake in improving sarcopenia. Therefore, additional studies are essential to examine the effects of MOP intake and exercise intervention on the body composition and fitness of patients over a longer period.

Given the central role of sense of control in physical and emotional well-being, the present study examined the determinants of sense of control among Korean elders. We considered sociodemographic characteristics (age, gender, marital status, education, and self-perceived economic status), health-related factors (chronic conditions, functional disability, and sensory impairment), stressful life events, and network-related resources (network of relatives, network of friends, and filial satisfaction) as potential predictors. Sense of control was measured with Pearlin and Schooler's (1978) Mastery Scale. Hierarchical regression analyses with 291 Korean elders aged 60 or older (M age = 69.9) identified lower self-perceived economic status, more chronic conditions, greater functional disability, greater vision impairment, more stressful life events, and lower filial satisfaction as significant risk factors for a diminished sense of control. Because most of the identified risks represent normative experiences during later life, the results underscored the importance of preserving or promoting sense of control for older adults. Implications of the findings and recommendations for future studies are discussed.

Purpose: The purpose of this study was to examine the effects of health promotion program on healthy aging preparation for late middle aged women. Methods: The research design was a non-equivalent control group quasi-experimental study. Participants were recruited from K and Y cities in Gyeong-nam Province from October, 2013 to January, 2014. They were 26 for the experimental group and 31 for the control group. The experimental group participated in a health promotion program for healthy aging preparation. The program consisted of education, exercise, and small group discussion over 8 weeks. Data were analyzed by Chi-square, t-test and ANCOVA, using the PASW 18.0 program. Results: There were significant improvements in aging anxiety and general self-efficacy, health promoting behaviors in the experimental group compared to those of the control group. However, there was no significant differences in attitude toward older adults between the two groups. Conclusion: The health promotion program on healthy aging preparation for late middle aged women was found to be effective in enhancing aging anxiety and self-efficacy, and health promoting behavior. Thus, the developed program is recommended for use in clinical practice as an effective nursing intervention for late middle aged women in order to keep up with their health in later life.

This study was conducted to determine which factors would predict metabolic syndrome (MetS) perception and exercise by applying a machine learning classifier, or Extreme Gradient Boosting algorithm (XGBoost) from July 2014 to December 2015. Data were obtained from the Korean Community Health Survey (KCHS), representing different community-dwelling Korean adults 19 years and older, from 2009 to 2013. The dataset includes 370,430 adults. Outcomes were categorized as follows based on the perception of MetS and physical activity (PA): Stage 1 (no perception, no PA), Stage 2 (perception, no PA), and Stage 3 (perception, PA). Features common to all questionnaires for the last 5 years were selected for modeling. Overall, there were 161 features, categorical except for age and the visual analogue scale (EQ-VAS). We used the Extreme Boosting algorithm in R programming for a model to predict factors and achieved prediction accuracy in 0.735 submissions. The top 10 predictive factors in Stage 3 were: age, education level, attempt to control weight, EQ mobility, nutrition label checks, private health insurance, EQ-5D usual activities, anti-smoking advertising, EQ-VAS, education in health centers for diabetes, and dental care. In conclusion, the results showed that XGBoost can be used to identify factors influencing disease prevention and management using healthcare bigdata.
