BACKGROUND: Glycemic control is an effective way to reduce the cardiovascular complications of diabetes, but more than half of the adults with diabetes in Korea are improperly controlling their glycemic levels. The purpose of this study is to identify the factors associated with poor glycemic control in type 2 diabetes patients. METHODS: This study analyzed 1,261 subjects ≥30 years old diagnosed with type 2 diabetes who participated in the fifth Korean National Health and Nutrition Examination Survey (2010-2012). Poor glycemic control rates were defined as hemoglobin A1c (HbA1c) level ≥7%. To shed light on the causes of poor glycemic control, socio-demographics, diabetes severity, health status, and health behavior factors were adjusted and logistic regression was done. RESULTS: Of the total 1,261 patients, 53.0% of patients with type 2 diabetes had HbA1c ≥7%. After running a logistic regression model, the odds ratio of poor glycemic control was higher in high school graduates than elementary school graduates; in people living in Chungcheong and Jeolla/Jeju than those living in Seoul; in the group with diabetes for over 5 years had diabetes less than 5 years; in a group with insulin and oral hypoglycemic agent treatment than non-treatment; in a group with hypertriglyceridemia than without hypertriglyceridemia; and in the group with slept less than 6 hours slept 7-8 hours. CONCLUSION: We need a comprehensive public health policy to reduce the poor glycemic control rates in type 2 diabetes patients. We should recognize the education levels, duration of diabetes, diabetes treatment, hypertriglyceridemia, and sleep duration were associated with poor glycemic control.

BACKGROUND: Family values of a married woman may be related to her own depressive mood. Since depressive mood of a married woman is likely to exert a negative influence, in terms of mental health, on her, her family members, and the whole society's, it may be very important to explore the relationship between family values in married women and their depressive mood. METHODS: In this study, we analyzed nationally representative 5,818 married women aged 20 years or older from the 4th panel data of 2012 Korean Longitudinal Survey of Women and Families. As for variables of interest, we constructed three family values variables: family-oriented view of marriage, individualistic view of marriage, and traditional view of marital roles. Then we employed multivariate logistic regression analyses to explore the relationship between family values and depressive mood, adjusting for family and socio-demographic factors. RESULTS: In total, 804 married women (18.4%) had experienced depressive mood. All of the three family values variables were significant in their relationships with depressive mood. The women categorized as ‘very weak’ in family-oriented view of marriage were more likely to experience depressive mood than the women categorized as ‘very strong’ (odds ratio [OR], 1.98; 95% confidence interval [CI], 1.53–2.55). By contrast, the women categorized as ‘very weak’ in individualistic view of marriage (OR, 0.43; 95% CI, 0.33–0.55) and in traditional view of marital roles (OR, 0.68; 95% CI, 0.51–0.92) were less likely to experience depressive mood than their respective counterpart women categorized as ‘very strong.’ CONCLUSION: In Korea, married women's values towards marriage itself and roles between wives and husbands had significant associations with their depressive mood. This suggests that in order to improve mental health in married women, we need to take social and cultural dimensions into consideration along with public health interventions.

Background:
As the population is aging, chronic diseases and depression are becoming the main problems in a country’s healthcare system. In this study, we aimed to explore the associations between chronic diseases and depression among the elderly in South Korea.
Methods:
We analyzed 9,975 (men, 4,147; women, 5,828) respondents obtained from the 2014 National Survey of Living Conditions and Welfare Needs of Korean Older Persons. Our dependent variable was either 1 or 0 according to whether a respondent had depression or not, where depression was defined when the Short Form of Geriatric Depression Scale score was 8 or more points. Variables of interest were 24 types of chronic diseases and covariates included various socio-demographic and health behavior characteristics. We performed Rao-Scott chi-square tests and hierarchal logistic regression analyses by gender, reflecting the characteristics of the survey.
Results:
A significant difference was found in the proportion of having depression between genders (men 18.9% vs. women 23.4%). According to fully adjusted, multivariable analyses, for elderly men, relative to those without any chronic disease, the odds ratio of depression was 1.56 (95% confidence interval [CI], 1.10–2.22) in the stroke patients group and 1.82 (95% CI, 1.01–3.25) in the osteoporosis patients group. For elderly women, the odds ratio was 1.96 (95% CI, 1.28–3.00) in the fracture/dislocation and aftereffects patients group and 1.30 (95% CI, 1.03–1.64) in the group of patients with other diseases.
Conclusion
Even after being adjusted for diverse characteristics, some chronic diseases were significantly associated with depression in the elderly and the association differed between genders. Therefore, public health and medical interventions are needed to manage such chronic diseases together with curing depression symptoms.

OBJECTIVES: To determine the impact of cigarette prices on the decision to initiate and quit smoking by taking into account the interdependence of smoking and other behavioral risk factors. METHODS: The study population consisted of 3,000 male Koreans aged > or =20. A survey by telephone interview was undertaken to collect information on cigarette price, smoking and other behavioral risk factors. A two-part model was used to examine separately the effect of price on the decision to be a smoker, and on the amount of cigarettes smoked. RESULTS: The overall price elasticity of cigarettes was estimated at -0.66, with a price elasticity of -0.02 for smoking participation and -0.64 for the amount of cigarettes consumed by smokers. The inclusion of other behavioral risk factors reduced the estimated price elasticity for smoking participation substantially, but had no effect on the conditional price elasticity for the quantity of cigarettes smoked. CONCLUSIONS: From the public health and financial perspectives, an increase in cigarette price would significantly reduce smoking prevalence as well as cigarette consumption by smokers in Korea.

OBJECTIVES: The purpose of this study was to estimate the willingness to quit cigarette price among Korean male adults, and to examine he factors affecting the willingness to quit cigarette price. METHODS: The data was collected by a random digit dial telephone survey. 702 samples were analyzed by using ttests, ANOVA and OLS regression analysis. To estimate the willingness to quit cigarette price, smokers were asked dichotomous questions with open-ended follow-up and the starting point of the price was randomized by one of 5 bid prices elicited from a pilot study. RESULTS: The mean of the willingness to quit cigarette price was 4,287 Won per package, which was about 2,000 Won higher than the mean of the actual price the smokers now paid. About 41% of respondents were willing to quit smoking if the price of cigarette would be increased by 3,000 Won, and if the price would be increased by 20,000 Won, all respondents were willing to quit smoking. The factors associated with the willingness to quit cigarette price were the place of residence, the amount of smoking and the degree of exposure to smoking through the mass media. CONCLUSIONS: The results showed that to get people to quit smoking, increasing the cigarette price would obviously be effective and much higher prices have a greater effect. Furthermore, to enlarge the effect of increased cigarette prices, providing more cessation programs to small towns, reducing the amount of smoking and decreasing or prohibiting advertisements of cigarettes and smoking in the mass media will be efficient.

Methods:
Seven human lumbopelvic spines were used, each affixed to six-degrees-of-freedom testing apparatus; 8.5-Nm pure unconstrained bending moments applied in flexion-extension, lateral bending, and axial rotation. The ROM of left and right SIJ was measured using a motion analysis system. Each specimen tested as (1) intact, (2) injury (left), (3) L5–S1 fixation, (4) unilateral stabilization (left), (5) unilateral stabilization+L5–S1 fixation, (6) bilateral stabilization, and (7) bilateral stabilization+L5–S1 fixation. Both left-sided iliosacral and posterior ligaments were cut for injury condition to model SIJ instability before surgery.
Results:
There were no statistical differences between fixated and contralateral nonfixated SIJ ROM following unilateral stabilization with/without L5–S1 fixation for all loading directions (p>0.930). Injured condition and L5–S1 fixation provided the largest motion increases across both joints; no significant differences were recorded between SIJs in any loading direction (p>0.850). Unilateral and bilateral stabilization with/without L5–S1 fixation reduced ROM compared with the injured condition for both SIJs, with bilateral stabilization providing maximum stability.
Conclusions
In the cadaveric model, unilateral SIJ stabilization with/without lumbosacral fixation did not lead to significant contralateral SIJ hypermobility; long-term changes and in vivo response may differ.

OBJECTIVES: Although vaccination rates have increased, problems still remain in the storage and handling of vaccines. This study focused on inspecting actual vaccine storage status and awareness, and comparing them before and after education was provided. METHODS: In the primary inspection, a status survey checklist was completed by visual inspection. A questionnaire on the awareness of proper vaccine storage and handling was also administered to vaccine administrators in private medical institutions in 4 regions in Gyeongsangbuk-province. One-on-one education was then carried out, and our self-produced manual on safe vaccine storage and management methods was provided. In the secondary inspection, the investigators visited the same medical institutions and used the same questionnaire and checklist used during the primary inspection. The results before and after education were compared, by treating each appropriate answer as 1 point. RESULTS: The average checklists score was 9.74 (out of 15 points), which increased significantly after education was provided (by 0.84, p<0.001). The participants demonstrated improved practices in recording storage temperatures (p=0.016), storing vaccines in the center of the refrigerator (p=0.004), storing vaccines with other medication and non-medical items (p=0.031) after education. The average score calculated from the questionnaires was 10.48 (out of 14 points), which increased after education (by 1.03, p<0.001). CONCLUSIONS: This study suggests that vaccine storage practices and awareness are inadequate, but can be partially improved by providing relevant education. Repetitive education and policy-making are required to store vaccines safely because one-off education and unenforced guidelines offer limited efficacy.

OBJECTIVES: The study is investigated socioeconomic variations in self-rated health status and contribution of health behavioral factors in Korea. METHODS: A nationally representative sample (2,800 men and 3,230 women aged 20-64 years) from the 2005 Korea National Health and Nutrition Surveys was analyzed using logistic regression. RESULTS: Self-rated health was lower among lower socioeconomic groups compared with higher socioeconomic groups, with gender being irrelevant. This association was attenuated when health behavioral and socio-demographic factors were adjusted. When each health behavioral factor was considered separately, mediators such as smoking in men, and stress or exercise in women explained a large part of the decreased socioeconomic health inequalities. CONCLUSIONS: In Korea, subjective health inequalities arise from different socioeconomic status, but this difference is decreased by health behavioral factors. Therefore, socioeconomic inequity in self-rated health status can be corrected more effectively by promotional health behaviors.

Economic evaluation is a type of comparative analysis between interventions in terms of both their resource use and health outcomes. Due to the good prognosis of thyroid cancer (TC), the socioeconomic burden of TC patients post-diagnosis is increasing. Therefore, economic evaluation studies focusing on TC are recommended. This study aimed to describe the concept and methods of economic evaluation and reviewed previous TC studies. Several previous studies compared the costs of interventions or evaluated recurrence, complications, or quality of life as measures of their effectiveness. Regarding costs, most studies focused on direct costs and applied hypothetical models. Cost-minimization analysis should be distinguished from simple cost analysis. Furthermore, due to the universality of the term “cost-effectiveness analysis” (CEA), several studies have not distinguished CEA from cost-utility analysis; this point needs to be considered in future research. Cost-benefit analyses have not been conducted in previous TC research. Since TC has a high survival rate and good prognosis, the need for economic evaluations has recently been pointed out. Therefore, correct concepts and methods are needed to obtain clear economic evaluation results. On this basis, it will be possible to provide appropriate guidelines for TC treatment and management in the future.
