Objectives: The purpose of this study is to examine and explain the extent of income-related inequity in health care utilization and expenditures to compare the extent in 2005 and 2010 in Korea. Methods: We employed the concentration indices and the horizontal inequity index proposed by Wagstaff and van Doorslaer based on one- and two-part models. This study was conducted using data from the 2005 and 2010 Korean National Health and Nutrition Examination Survey. We examined health care utilization and expenditures for different types of health care providers, including health centers, physician clinics, hospitals, general hospitals, dental care, and licensed traditional medical practitioners. Results: The results show the equitable distribution of overall health care utilization with pro-poor tendencies and modest pro-rich inequity in the amount of medical expenditures in 2010. For the decomposition analysis, non-need variables such as income, education, private insurance, and occupational status have contributed considerably to pro-rich inequality in health care over the period between 2005 and 2010. Conclusions: We found that health care utilization in Korea in 2010 was fairly equitable, but the poor still have some barriers to accessing primary care and continuing to receive medical care.

BACKGROUND/OBJECTIVES: The commercial foodservice industry in Korea has shown rapid growth recently. This study examined Korean adults' consumption of commercially-prepared meals based on where the food was prepared. SUBJECTS/METHODS: Data from a 24-hour dietary recall of the 2001 and 2011 Korea National Health and Nutrition Examination Surveys were analyzed. A total of 10,539 subjects (n = 6,152 in 2001; n = 4,387 in 2011) aged 19-64 years were included for analysis. Commercially-prepared meals were classified into four food source groups based on where the food was prepared: Korean restaurants, Chinese/Western/Japanese restaurants, fast-food restaurants, and retail stores. Subjects' energy intake, including the amount and proportion of calories, was examined for each food source. The analysis was also conducted by gender for age-stratified groups: 19-29, 30-49, and 50-64 years old. RESULTS: Korean adults' energy intake from commercially-prepared meals increased in the amount of calories (551 kcal to 635 kcal, P < 0.01), but not in the proportion of daily calories (27% to 28%) from 2001 to 2011. The most frequent food source of commercially-prepared meals was Korean restaurants in both years. The amount and proportion of calories from retail stores increased from 83 kcal to 143 kcal (P < 0.001) and from 4% to 7% (P < 0.001), respectively, during the same period. Males aged 30-49 years (34%) and females aged 19-29 years (35%) consumed the highest proportion of daily calories from commercially-prepared meals in 2011. CONCLUSIONS: Korean adults consumed about one-fourth of their energy intake from commercially-prepared meals. In particular, males aged 30-49 years and females aged 19-29 years consumed more than one-third of their energy intake from commercially-prepared meals. Korean restaurants played a significant role in Korean adults' energy intake. Retail stores increased influence on Korean adults' energy intake. These results could be useful for developing health promotion policies and programs.

Family type is not only an important sociodemographic variable for health studies but also influences the health behavior and health condition of individuals. This study assessed a representative sample to see whether family type is associated with health behavior in Korean adults age 65 and older. This is a cross-sectional study of 9,535 Korean elderly who participated in the 2010-2012 Korean National Health and Nutrition Examination Survey. The subjects were classified as couple cohabitation, couple-offspring cohabitation, alone, or alone-offspring cohabitation. We assessed the relationship between family type and six health behaviors (smoking, high risk drinking, walking, oral examinations, health screenings, and influenza vaccinations) after controlling covariates. The "alone" classification had a significantly higher risk of no health screening, but was more likely to have an influenza vaccination than couples. Significant interactions between family type and healthy behavior were observed with oral health screening, influenza vaccination, and smoking {Odds ratio (95% confidence interval), 1.452 (1.066-1.980), 1.375 (1.083-1.747), 2.246 (1.604-3.146)}. There is a significant association between family type and healthy behaviors.

Objectives: A cross-sectional study was conducted to investigate the associations between food groups and hearing loss. Methods: Data of 1,312 individuals were used from the Korea National Health and Nutrition Examination Survey 2013. Hearing loss was determined with a pure tone average (PTA) of greater than 25 dB in either ear. The PTA was measured as the average hearing threshold at speech frequencies of 0.5, 1, 2, and 4 kHz. The dietary intake was examined with a food frequency questionnaire with 112 food items. The food items were classified into 25 food groups. A weighted logistic regression was used to investigate the association. Results: Individuals in the highest tertile of vegetables and nuts food groups were less likely to have hearing loss than those in the lowest tertile [Odds Ratio (OR) = 0.58 (95% Confidence interval (CI) 0.38-0.91), P = 0.019; OR = 0.59 (95% CI 0.39-0.90), P = 0.020, respectively], after adjusting for confounding variables of age, sex, body mass index, drinking, smoking, diabetes, hypertension, and physical activity. Conclusions: In this cross-sectional study, we observed that high intake of vegetables and nuts food groups revealed significant inverse associations with hearing loss, after adjusting for confounding variables among 1,312 participants.

Objectives: This study aims to examine hypertension patients' quality of life by using the data of the 7^th Korea National Health and Nutrition Examination Survey (1^st year, 2016), identify the factors related to this, and utilize the results as basic data for intervention that can improve hypertension patients' quality of life. Methods: For the research subjects, this study extracted 1,531 patients who were diagnosed with hypertension by a doctor from the total sample of 8,150 participants of the 7^th Korea National Health and Nutrition Examination Survey, and selected 1,072 patients with no missing value in the variables to be analyzed as the final research subjects. The SPSS(version25.0) program was used for the analysis of the collected data. Then, this study used a backward elimination multiple regression analysis method that applied complex sample, to examine the factors related with the finally estimated quality of life. Results: The results of this study revealed that hypertension patients' quality of life was related with age, occupation, spouse, household income, weight gain, restriction of activity, subjected health status, perceived stress, and presence of comorbidity. The final model explained 37.0% of the variance (Wald F=30.012 p<.001). Conclusions: When an intervention program is implemented for the improvement of hypertension patients' quality of life in the future, it will be effective to construct the program according to age group, employment, marital status and household income. As for the program operation, patients should get help therefrom to control weight, facilitate activities and relieve their stress, and they should be also motivated to feel healthy. Furthermore, education should be offered so that they appropriately manage their underlying disease at an early stage.

This study aimed to evaluate the health concern, eating habits, dietary behavior, and psychological stress among middle-aged adults in Chungnam according to their exercise status. A total of 437 adults with a mean age of 42.6 years participated in this study and completed a questionnaire survey. The subjects were divided into one of three groups according to their exercise status: never doing exercise (NDE; n=144), doing exercise once a week (DEO; n=186), and doing exercise twice a week or more (DET; n=107). Results demonstrated significant differences in concern about health, subjective health status, meal regularity, dietary problems, and stress score among the three groups. The DET and DEO groups were more concerned about their health (p<0.001), and had a perception that their health status was better than that of the NDE group (p<0.01). A larger percentage of the DET group had breakfast everyday (p<0.05) and a smaller percentage of the DET group had dietary problems such as irregular mealtime and skipping meals (p<0.01), compared to the other groups. The average stress score of the DET group was significantly lower than that of the DEO and NDE groups (p<0.05). The results reveal that doing regular exercising at least twice a week is associated with higher health concern, more desirable dietary habits, and lower psychological stress in middle-aged adults. These findings support the beneficial effects of regular exercise for health, dietary habits, and stress control.

Objectives: This study evaluated dietary behavior and nutritional status according to the metabolic syndrome status in Korean menopausal women. Methods: The subjects were 1,392 menopausal women aged 50 to 64 who took part in the Korea National Health and Nutrition Examination Survey of 2016 and 2017. Subjects were classified into normal (NOR) group, pre-metabolic syndrome (Pre-MetS) group, and metabolic syndrome (MetS) groups according to the number of metabolic syndrome risk factors present. Results: The overall prevalence of metabolic syndrome was 33.7%. Using the NOR group as a reference, the odds of belonging to the MetS group in Model 1 adjusted for age were higher at 53% (OR = 1.53, 95% CI:1.011-2.307) for 'not used' subjects compared to 'used' subjects of the nutrition labeling system. Using the NOR group as a reference, every 1g increase in the intake of monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) decreased the odds of belonging to the MetS group in Model 1 adjusted for age by 3% (MUFA, OR = 0.97, 95% CI:0.946-0.991; PUFA, OR = 0.97, 95% CI:0.942-0.993). Conclusions: These results suggest that to reduce the number of risk factors of metabolic syndrome in menopausal women, nutritional education should emphasize the adequate intake of riboflavin, unsaturated fatty acids, protein, and calcium, and also encourage the recognition and use of nutritional labeling. Results of this study are expected to be utilized as basic data for the health management of menopausal women.
