This study explored how retirement satisfaction or dissatisfaction influences on retirees' life satisfaction, comparing to workers and the gender differences were examined. The study sample was 2,609 persons (1,886 workers, 723 retirees) aged 45 or older who participated in the 1-2 waves of the Korean Longitudinal Study of Ageing (KLoSA), and the retirees were classified into continuously dissatisfied retirees and satisfied retirees during wave 1 and 2. Using SPSS 21.0, the multiple regression models were examined, and in order to clarify the gender difference, the multi-group analysis and the wald-test were conducted to test the difference of the regression coefficients according to gender using Mplus 7.3. According to the results, the life satisfaction of dissatisfied retirees was lower than that of the employed, but when satisfied with retirement, the life satisfaction was higher than that of the employed. In addition, the dissatisfied retirees in both gender were less satisfied with life than the employed, and this effect was greater in female group. However, the life satisfaction of female satisfied with retirement was higher than that of the employed, whereas the evidence of the male influence was not found to be significant. Based on the results of this study, discussion about heterogeneity of retirees and gender differences in life span were presented.

BACKGROUND/OBJECTIVES: The inverse relationships of combined fruits and vegetables intake with blood pressure have been reported. However, whether there are such relationships with salty vegetables has rarely been investigated in epidemiologic studies. We evaluated the relation of combined and separate intake of fruits, vegetable intakes, and salty vegetables, as well as sodium and potassium, with blood pressure among the middle-aged and elderly populations. SUBJECTS/METHODS: The present cross-sectional analysis of a prospective cohort baseline survey was performed with 6,283 subjects (2,443 men and 3,840 women) and free of hypertension, diabetes, cardiovascular diseases, and cancer. Dietary data were collected by trained interviewers using food frequency questionnaire. RESULTS: The significantly inverse linear trend of diastolic blood pressure (DBP) was found in fruits and non-pickled vegetables (81.2 mmHg in the lowest quintile vs 79.0 mmHg in the highest quintile, P for trend = 0.0040) and fruits only (80.9 mmHg in the lowest quintile vs 79.4 mmHg in the highest quintile, P for trend = 0.0430) among men. In contrast, sodium and sodium to potassium ratio were positively related with blood pressure among men (DBP, 78.8 mmHg in the lowest quintile vs 80.6 mmHg in the highest quintile, P for trend = 0.0079 for sodium; DBP, 79.0 mmHg in the lowest quintile vs 80.7 mmHg in the highest quintile, P for trend = 0.0199 and SBP, 123.8 mmHg in the lowest quintile vs 125.9 mmHg in the highest quintile for sodium/potassium). Kimchies consumption was positively related to DBP for men (78.2 mmHg in the lowest quintile vs 80.9 mmHg in the highest quintile for DBP, P for trend = 0.0003). Among women, these relations were not found. CONCLUSION: Fruits and/or non-pickled vegetables may be inversely, but sodium, sodium to potassium, and Kimchies may be positively related to blood pressure among men.

To assess the quality of nutrient intake by area of Korean adults, a dietary survey with the 3-day record method was obtained from 324 subjects aged 40 years and older but younger than 70 (52.4 $\pm$ 8.7) living in a rural area (Ansung) and suburban area of a middle-sized city (Ansan). The quality of nutrient intake was assessed by analyzing Nutrient Adequacy Ratio (NAR), Mean Adequacy Ratio (MAR) and Index of Nutritional Quality (INQ). The average daily mean energy intakes were 1,832 ㎉ for Ansung and 1,842 ㎉ for Ansan, respectively. Daily intakes of fat for Ansung and Ansan subjects were 40.9 and 40.3 g, and those for protein were 75.1 and 73.1 g, respectively. The overall calorie: protein: fat ratio (CPF) of energy intake was 63 : 17 : 20. Daily mean intakes of protein, fat, calcium, phosphorus, iron, potassium, carotene, sodium, thiamin, and niacin were significantly higher in Ansung residents than in Ansan subjects (p < .05). The average intakes of energy, calcium, vitamin A were lower than Recommend Dietary Allowance (RDA) in both areas. Note, over 30% of the study subjects had less than 75% of RDA of calcium, vitamin A and riboflavin. The MAR was higher in Ansung than Ansan residents (0.86 and 0.85, respectively; p < .05). INQs were over 1 for most nutrients except calcium (0.87), and that of calcium and phosphorus was each significantly higher in Ansung than Ansan subjects. Based on these results, nutrient intake quality of subjects aged 40 to 69 years living in the surveyed rural area is comparable to that of semi-industrialized suburban area in Korea. Dietary deficiency in all of calcium, vitamin A, and riboflavin, however, was a common problem for both rural and suburban residents.

Purpose: The purpose of this study was to investigate the effects of nutrient intake and dietary diversity score (DDS) on osteoporosis after controlling for sex, age, socioeconomic level, drinking, smoking, physical activity, and body mass index (BMI) as mediators using the 2015-2017 Korean National Health and Nutrition Examination Survey (KNHANES) data. Methods: This study was focused on the age group of 50s and older by using the 2015-2017 KNHANES data. Subjects diagnosed with osteoporosis were classified as the osteoporosis group, and the other subjects were classified as the normal group. Logistic regression was used to assess the association between nutrient intake and DDS after controlling for mediators. Results: The risk of osteoporosis was 2.38 times lower in the 50-65 age group than in the 75 years and older group. The mediators affecting the incidence of osteoporosis by age group were sex, age, household income level, and education level in the 50-64 age group; sex, education level, drinking, and BMI in the 65-74 age group; and sex, age, current smoking, drinking, BMI, and energy intake in the 75 years and older group. The effect of nutrient intake on osteoporosis, with the exception of vitamin B1, was fully mediated by these mediators. The effect of vitamin B1 was partially mediated by mediators in the age group of 65-74 years, and vitamin B1 was effective for preventing the risk of osteoporosis by 25% when consumed over EAR. The effect of DDS was partially mediated in the age group of 75 years and older, and DDS of 2 or less increased the risk of osteoporosis by 2.59 times. Conclusion: As a result of this study, it is necessary to recommend the balanced intake of various foods including grains, meat·fish·legumes, vegetables, fruits, and dairy products as dietary guidelines for the prevention of osteoporosis and promotion of bone health in the elderly.

The purpose of this study was to identify the relation of health behaviors and the quality of life by life cycle of hypertensive patients. This study was conducted by analyzing secondary data with data from the 2017 Community Health Survey. The subjects were total of 62,056 who were diagnosed with hypertension and analyzed using the SPSS WIN 20.0 program. As a result of the study, As a result of the study, first, hypertension treatment and drug compliance were significantly lower in adulthood than in middle-aged and older adults. Second, it was confirmed that the quality of life score by life cycle was the highest in adulthood and decreased as age increased. Third, the quality of life according to health behaviors differed according to drinking, exercise, and low-salt diet throughout the life cycle. Considering the results presented in this study, it is suggested that health education by life cycle is essential for lifelong health management of hypertensive patients. In particular, it is considered that a convergence approach such as education and medical approaches will be needed to develop measures to increase drug compliance in adult hypertensive patients and to have healthy health behaviors to improve quality of life.

Objectives Impaired lung function(ILF) and sasang constitution(SC) is associated with metabolic syndrome(MS). However, the relationship between ILF and SC is unclear. So, we assessed the relationship between ILF and MS according to SC, and examined whether SC is an independent risk factor for ILF. Methods This study included 1,148 subjects 40years and older who were performed the health examination at Kyung Hee University Hospital in Korea between December 2011 and February 2013. We defined ILF if FVC or $FEV_1$ value were less than lower limit of normal(LLN), and classified ventilatory patterns as obstructive pattern and restrictive pattern. MS was assessed according to AHA/NHLBI criteria. We used multivariate logistic regression to analyze the association of ILF with MS respective to SC types, and to identify the risk of SC types for ILF. Odds ratio(OR) was calculated by adjusting for age, sex, smoking status, drinking, physical activity, and BMI. Results In whole subjects, ILF was associated with MS [OR (95% CI), 1.69 (1.24-2.31) for FVC, 1.67 (1.20-2.33) for $FEV_1$]. And in Taeeum type(TE type) and Soeum type(SE type), ILF was associated with MS [1.63 (1.10-2.42) for FVC, 1.48 (1.01-2.24) for $FEV_1$ in TE type; 6.93 (1.14-42.00) for FVC in SE type], while in Soyang type(SY type), it wasn't. The restrictive pattern was associated with MS in TE type and SE type, while in SY type, it wasn't. Furthermore, TE type and SY type had more risk for ILF than SE type [1.71 (1.12-2.59) for SY type, 1.95 (1.23-3.08) for TE type in FVC; 2.06 (1.26-3.36) for TE type in $FEV_1$; 1.85 (1.21-2.85) for SY type, 2.17 (1.35-3.49) for TE type in Restrictive pattern]. Conclusions These results show that SC is an independent risk factor for ILF, especially TE type and SY type than SE type, and the prevalence of MS is an independent risk factor for ILF in TE type.

This study was carried out to obtain information regarding eating habits, including health related behavior and health food consumption patterns. The subjects of this study were 149 men and 152 women residing in the Ulsan area. We obtained results by means of a questionnaire and an interview, and these were analyzed using the SPSS package program. The results of this study are summarized as follows The average age of the men was 47.6 $\pm$ 7.3 years and of the women was 47.3 $\pm$ 7.6 years old. The average height and weight of the men were 169.4 $\pm$ 5.5 cm and 67.7 $\pm$ 8.2 kg, respectively. Those of the women were 157.6 $\pm$ 5.0 cm and 58.2 $\pm$ 7.5 kg, respectively. The BMI values of all the subjects ranged from 20.0 to 25.0, all within the normal levels. In the case of dietary patterns, 24.3% of the total population always skipped a meal. In particular, 15.9% of the total population skipped breakfast. No time to eat, no appetite, having no taste, and having poor health were themain reasons for skipping meals. With regard to health care, there was a significant difference between the men and the women with respect to smoking and drinking (p<0.001). Of the total population, 40.5% hardly exercised (less than once a week), 26.2% exercised occasionally, 13.6% frequently exercised, and 19.6% exercised almost every day. A total of 60.7% responded that they were not interested in their health. The mean eating habit score of the subjects was 65.6 $\pm$ 9.9. The women had a higher eating habit score than the men (64.0 $\pm$ 9.6 for the men and 67.2 $\pm$ 9.9 for the women). Except for one group above 60 years, the older group had a higher eating habit score than the younger one. The group having a higher income and a more specialized career had a higher eating habit score than the one having a lower income and a less specialized career. There was also a marital difference. The group of single subjects showed a lower eating habit score than the married group. The group having a higher eating habit score drank, smoked and went out for meals less, and exercised more than the group having lower scores. They also were more concerned about their health. In the older group, there were more diabetic and hypertensive individuals. The subjects who had a higher BMI index were more likely to be patients with hypertension, especially in the men's group. Those who had a higher BMI index and hypertension simultaneously took a variety of medicines and foods for promoting health. Those who worried a lot about their health and had health problems tended to take special foods for their health. Patients usually took tonics. Special foods for health included Chinese medicines, tonic foods, vitamin or mineral supplements and manufactured health food supplements. Preferences for them depended on the sex and age of the subject. In the case of tonic foods, the men liked them more than the women. Foods other than tonic foods were favorites with the women. This study may provide basic information on the eating habits and health related behaviors of middle-aged people. However, further studies are needed to improve the eating habits and to change the nutritional attitudes, so that people can make better choices of health foods.

This study is to look at the risk of chronic diseases in adults and oral health behaviors affecting periodontitis by gender. This study selected 3,071 males aged 35 to 65, 4,273 females, and 7,344 people as the final subjects of the study using the sixth original data from the National Health and Nutrition Survey. In this study, subjective oral health classified under 'bad' presented 1.69 times(p<0.001) the risk of Periodontitis for males and 1.50 times(p<0.001) for females. There was a 2.01 times(p<0.001) of a risk of periodontitis for male and 1.40 times(p=0.001) of a risk for females. Smokers have a 1.68 times(p<0.001) of a risk for males and 2.07 times(p<0.001) of a risk for females, thus a higher risk for periodontitis for females. The risk of periodontitis was 1.44 times(p<0.001) of a risk for males and 1.30 times(p<0.05) for females when compared in normal hypertension. Obesity was at a rate of 1.199 times(p<0.05) as much for males in the non-military group, 1.202 times(p<0.05) that of females for periodontitis and putting females slightly more at risk. For diabetes, males were at risk of 1.28(p<0.05) whereas it being 1.53 times(p<0.05) for females, compared the average health female. In total, Males were found to be at the greatest risk of periodontitis, while women were at the highest risk for smoking. All parameters except smoking and diabetes show a higher risk of periodontitis for females. As males are more likely to have a higher risk of periodontitis than females, they are considered to be more interested in oral health care and need systematic oral health education and policies to prevent oral diseases.
