류소연,최성우,한미아,박종 대한예방의학회 2014 Journal of Preventive Medicine and Public Health Vol.47 No.2

Objectives: Several previous studies have found that healthy behaviors substantially reduce non-communicable disease incidence and mortality. The present study was performed to estimate the prevalence of four modifiable healthy behaviors and a healthy lifestyle among Korean adults according to socio-demographic and regional factors. Methods: We analyzed data from 199 400 Korean adults aged 19 years and older who participated in the 2010 Korean Community Health Survey. We defined a healthy lifestyle as a combination of four modifiable healthy behaviors: non-smoking, moderate alcohol consumption, regular walking, and a healthy weight. We calculated the prevalence rates and odds ratios of each healthy behavior and healthy lifestyle according to socio-demographic and regional characteristics. Results: The prevalence rates were as follows: non-smoking, 75.0% (53.7% in men, 96.6% in women); moderate alcohol consumption, 88.2% (79.7% in men, 96.9% in women); regular walking, 45.0% (46.2% in men, 43.8% in women); healthy weight, 77.4% (71.3% in men, 73.6% in women); and a healthy lifestyle, 25.5% (16.4% in men, 34.6% in women). The characteristics associated with a low prevalence of healthy lifestyle were male gender, younger age (19 to 44 years of age), low educational attainment, married, living in a rural area, living in the Chungcheong, Youngnam, or Gwangwon-Jeju region, and poorer self-rated health. Conclusions: Further research should be implemented to explore the explainable factors of disparities for socio-demographic and regional characteristics to engage in the healthy lifestyle among adults.

This prospective study was performed to find the associated factors of obesity in primary school children in Kwangju. We studied obesity incidence over 2 years among 4th grade primary school children, In 1994, base line study about 1,344 children of 4th grade was performed and in 2 years later, we reinvestigated health examination and questionnaire about several variables in 922. The 797 children included in the analysis had non-obese(normal and overweight) at baseline in 1994. This results were as follows; l. In 2 years later, 3.5% of normal and 15% of overweight children were to the obese. 2. The body mass index and obesity in one or both parents, sex, overweight at baseline, regular exercise and meat preference were statistically significant factors in simple analysis. 3. In multiple logistic regression analysis, the odds ratios associated with obesity were 0.41 (95% CI: 0.20-0.82) for female, 0.48(95% CI: 0.25-0.92) for doing regular exercise, 4,95(95% CI: 2.55-9.59) for overweight at baseline, and 3.22(95% CI: 1.11-9.34) for obesity in both parents. In conclusion, obesity incidence in primary school children was associated with physical characteristics, genetic factors and social factors like a life style. It is suggested that obesity management and appropriate regular exercise in family unit should be required to prevent obesity in children.

Objectives : This study was performed to investigate the drinking status and the related factors with problem drinking in some medical students. Methods : The study subjects were 345 premedical students (freshmen and sophomore) and medical students (sophomore) in a medical school who replied to the self-administered questionnaire survey during March 2002. The questionnaire was composed of general characteristics, drinking status, social value about drinking, health status, satisfaction of life and alcohol use disorders identification test (AUDIT) . Results : The experience rate of drinking was 88.8% in male and 88.3% in female and it was tended to increase with going up the grade. Prevalence of hazardous, dependence, harmful and problem drinking classified by AUDIT score criteria were 66.2%, 3.0%, 7.0% and 5.1% in male and 34.9%, 0.9%, 1.9%, 1.9% in female. In male, the statistically significant related factors to Al JDIT scores were grade, religion, maternal drinking status, social value about drinking, affectionate feelings of those around one and satisfaction of life. Only social value about drinking was statistically significant correlated factor with AUDIT scores in female. As a result of multiple regression analysis, the related factors with AUDIT scores were sex, maternal drinking status, satisfaction of life and social value a bout drinking. Conclusion : The experience rate of drinking in medical students was higher than that in other college students. Grade, family drinking history, negative psychological feelings, social value about drinking were risk factors to problem drinking.

This study aimed to improve the moisture resistance of salt cores by investigating the suitability of a two-dimensional kaolinite colloidal solution and a commercially available SiO2 ink solution as coating agents. X-ray diffraction analysis (XRD) results showed that the intercalation of urea into kaolinite did not significantly change its layer structure. Scanning electron microscopy (SEM) images revealed that the dip-coating only affected the surface of the salt core, and the texture of the surface is differ depending on the coating solution. The humidity absorption test results showed that both coatings reduced the hygroscopicity of the salt core by more than 50%. However, in the water-solubility test, the kaolinite dissolved with the salt core, whereas the SiO2-coated salt core left a residue. These results strongly suggest that with the coating of the exfoliated kaolinite solution, salt core will remain stable in humid environments.

Using pulmonary function and questionnaire data for 127 primary-school-age children (62 boys and 65 girls) in Kwangju city, we analyzed spirometric data (FVC. FEV_0.5, FEV_1, FEV_3, FEF_200-1200, FEF_25-75%) to determine the factors affecting the pulmonary function in 3 primary schools. The results were as follows; 1. Boys had higher value of spirometric data than do girls. 2. Obese children were tended to lower value of spirometric data than non-obese children in both sexes. 3. FEF_200-1200 were higher for taking exercise group than for not taking exercise group in boys. 4. FEV_0.5, FEF_200-1200, FEF_25-75% in boys and FVC and FEV_3 in girls were higher for group whose sleeping hours is less than 8 hours per day than for group whose sleeping hours is more than 8 hours per day. 5. Non-smoking status was associated with higher FVC, FEV_1, FEF_200-1200 in girls. 6. Spirometric data were correlated very strongly with height, weight, age in both sexes and there was a significant correlation between sleeping hours and spirometric data except FEF_25-75% and familial smoking amount and FVC in girls. We conclude that the management and education of environmental factors may be needed to improve pulmonary functions.

Objectives : To investigate the relationship of serum uric acid to cardiovascular risk factors in Korean male workers. Methods : We screened 522 male workers at an electrical manufacturing company by a periodic health examination and a questionnaire survey in 2000. We collected data relating to age, smoking status, alcohol drinking status, body mass index (BMI), blood pressure, serum lipid, fasting blood glucose and serum uric acid. The data were analyzed using a variety of methods, including ANOVA, Pearson's correlation, and multivariate regression analyses. to examine the association between uric acid and cardiovascular risk factors with a cross-sectional study design. Results : The concentration of serum uric acid showed positive associations with BMI, total cholesterol, triglyceride, and LDL-cholesterol; it was also significantly correlated to systolic and diastolic blood pressures. Life-style characteristics, such as smoking and alcohol drinking showed no significant association. From the multivariate regression analyses, BMI, total cholesterol and fasting blood glucose levels were found to be independent positive predictors of uric acid; while age, blood pressure and smoking status give no independent contribution explaining the variability of serum uric acid levels. Conclusions : This study demonstrates that serum uric acid level have a significant association with cardiovascular risk factors, such as BMI, total cholesterol and blood glucose in some Korean male workers.

Objectives: This study was performed to find the association between smoking experiences and psychological factors such as depression and self-esteem in middle school students. Methods: The data were collected by self-administered questionnaires from 1,995 students in 10 middle schools in a district of Gwangju, and analysed using chi-square test, t-test and multiple logistic regression analysis. Results: The rate of smoking experience was 29.6% for male and 14.5% for female students (p<0.05). Students who had ever smoked were more depressed and lower self- esteem than those who did not smoke. After adjustment for the effect of potential covariates, those students who depressed were more likely to have smoking experiences (aOR= 1.87, 95% CI=1.51~2.31), compared with who did not depressed. And those students in the highest 25% (4th quartile) of the self-esteem were less likely to have smoking experiences (aOR=0.61, 95% CI=0.38~0.87), compared with the lowest quartile group. Conclusions: The results of this study suggest that psychological factors were associated with student smoking. There is therefore a need for school-based smoking prevention programs, which deal comprehensively with socio-demographic factors, environmental factors and psychological factors that influence smoking.

Objectives : This study was performed to investigate the association between serum gamma-glutamyltransferase (GGT) and the metabolic syndrome (MS) in Korean adolescents. Methods : Data were obtained from 1,372 students aged 12~13y with normal liver functions of 7 middle schools in a district of Gwang-ju. Serum GGT, alanine aminotransferase (ALT), body mass index(BMI), waist circumference, blood pressure, fasting glucose and lipid profiles were measured. MS was defined by criteria analogous to ATP Ⅲ as ≥3 of the following: 1) fasting triglycerides ≥100 mg/dL, 2) HDL-cholesterol <50 mg/dL, 3) fasting glucose ≥110 mg/dL, 4) waist circumference >75th percentile for age and gender, and 5) systolic blood pressure >90th percentile for gender, age, and height. GGT quartiles were formed in assessing the likelihood of MS in logistic regression models that controlled for confounders such as sex, overweight and serum ALT. Results : The prevalence of MS was 5.2% (5.6% for male and 4.9% for female). The MS and its components were significantly related to increased serum GGT level except for HDL-cholesterol and fasting glucose. After the adjustment for sex, overweight and serum alanine aminotransferase (ALT), the association with the MS was attenuated, but the OR for MS was 2.06 (95% Confidence Interval: 1.02~4.17) in the highest compared with the lowest quartile of serum GGT. Conclusions : This study shows that serum GGT level, even within its normal range, is associated with the MS in Korean adolescents.

In this paper, a change of fracture toughness and hardness in PZT-PYW ceramics system before and after poling treatment was measured to investigate the effect of composition on the mechanical properties in PZT-PYW ceramics. The hardness of the PZT-PYW ceramics increased with increasing mole fraction of PYW. The fracture toughness achieved maximum values for x=0.03. Both of the hardness and the fracture toughness also increased with poling treatment. The variation of both hardness and fracture toughness with increasing PYW mole fracture was explained by the change in microstructures such as grain size and second phase. The difference in hardness and fracture toughness in the electrically poled and unpoled specimens was also explained on the bases of internal stress.

This study was performed to find the prevalence and the associated risk factors with low back pain(LBP) of the staffs in a university at Kwang-ju city. The data were collected by a questionnaire including SDS(self - rating depression Scale) battery from September 1st to October 15th, 1996. The results were as follows; 1. The prevalence rate of LBP during lifetime was 73.1%, 53.1% for the last one year, and 23.6% for the last one week. 2. Statistically significant factors related to LBP during lifetime were sex and satisfaction with job. Sex, smoking, alcohol drinking, occupation, work posture, forward bending of trunk and satisfaction with job were selected as significant factors related to LBP during the last one year. The significant determinants related with LBP during the last one week were sex, smoking, alcohol drinking, occupation, forward bending of trunk and satisfaction with job. 3. Through the analysis of self - rating depression scores according to LBP, respondents with LBP had the significantly higher value of physiological disturbances and lower value of psychomotor activities than those without LBP. 4. Through the multivariate logistic regression, significantly associated factors with LBP during lifetime were selected to be female(OR=2.63, 95% CI : $1.08\sim6.40$), dissatisfaction with job(OR=2.16, 95% CI : $1.16\sim4.15$), those for the last one year were chosen to be female(OR=2.30, 95% CI : $1.03\sim5.12$), forward bending of trunk(OR=2.18, 95% CI : $1.26\sim3.79$), dissatisfaction with job(OR=1.84, 95% CI : $1.06\sim3.21$), and those for the last one week were female(OR=3.00, 95% CI : $1.17\sim7.69$), forward bending of trunk(OR=2.85, 95% CI : $1.38\sim5.88$). In conclusion, for effective prevention of the LBP at work site, appropriate improvement of work posture and various psychological factors should be considered.
