This study was conducted to analyze the relationship between the practice of aerobic exercise and the prevalence and risk of arthritis with comorbid chronic diseases. For this study, the National Health and Nutrition Examination Survey 2017-2019 data were used and 17,356 people were selected as subjects. The relationship between the practice of aerobic exercise and the prevalence and risk of arthritis according to demographic characteristics and chronic diseases was analyzed by the chi-square independence test and Breslow-Day test. While the rate of aerobic exercise was low among women, the elderly, the low-income group, the low-education group, and people living in rural areas, the prevalence and risk of arthritis were relatively high. And in the chronic disease-positive group, those who practiced aerobic exercise had a relatively lower prevalence and risk of arthritis than those who did not. In particular, the practice of aerobic exercise was an effective complement in reducing the prevalence and risk of arthritis in people with high blood pressure, diabetes, and dyslipidemia. Therefore, the practice of aerobic exercise such as walking, slow running, and aerobic dance should be recommended in terms of the preventive medicine and health care to people who are in the group with a high prevalence of arthritis in demographic characteristics and people who have comorbid chronic diseases.

Objectives: The aim of this study was to investigate the number of existing permanent teeth and the denture usage status in elderly adults aged 65 years and above living in metropolitan cities and to confirm the degree of oral health inequality caused by the differences in oral conditions in each metropolitan city using the Lorenz curve and the Gini coefficient. Methods: The raw data for the analysis were obtained from the dataset of the sixth Korea National Health and Nutrition Examination Survey conducted between 2013 and 2015. The subjects included 1,764 people who underwent oral examination and answered questions. The complex samples general linear model was used to analyze the number of existing permanent teeth adjusted for age and monthly household income. The proportion of edentulousness and the denture status was analyzed using complex samples crosstabs. Results: The number of existing permanent teeth in the elderly adults aged 65 years and above was lowest in Ulsan (15.41) and highest in Gwangju (20.44). The proportion of edentulousness was highest in Busan (14.5%) and lowest in Daejeon (4.0%). With regard to the proportion of denture users, Busan had the highest tendency for denture usage (50.4%) and Gwangju had the lowest tendency (34.9) (p=0.172). The Gini's coefficient for the number of existing teeth was lowest in Busan (0.332). Oral health inequality was most severe in metropolitan cities. Conclusions: We found that oral health inequality exists among elderly adults living in the metropolitan cities of Korea using the Lorenz curve and Gini's coefficient.

Objective : Smoking can increase the risk of secondary conditions for people with disabilities, which can in turn counteract primary disorders and exacerbate existing disorders. More active interventions for smoking cessation are necessary for people with disabilities because the physical condition of people with disabilities is more vulnerable, and risk factors such as smoking, drinking, obesity, and stress can have a decisive influence on people with disabilities compared to non-disabled people. Methods : In this study, the subjects who participated in National Health and Nutrition Survey of 2013 were those aged over 19 and smoker. The final 299 people with disability and 4,260 people without disability were analyzed. Results : Current smoking rate was 21.5% of non-disabled people and 21.4% of disabled people respectively. Factors influencing the current smoking rate of the disabled people were analyzed by type of household, economic status, home ownership, drinking, binge drinking, activity limit. Conclusions : In order to reduce socioeconomic inequalities of smoking and to actively intervene with the disabled, there need a new approach strategy focusing on people with disabilities.

This study was conducted to analyze with a focus on gender whether the prevalence of hyperuricemia varies depending on sitting time and high-risk drinking by occupational group. For this study, the Korea National Health and Nutrition Examination Survey data were used, and 16,366 people were selected. The chi-square independence test and logistic regression model were used as the analysis method. The prevalence and risk of hyperuricemia by sitting time were different in the 'agricultural, forestry and fishery skilled workers' only in men. On the other hand, the prevalence with high-risk drinking, both men and women showed differences in 'managers, experts and related workers' and 'office worker'. Also, only women have differences in 'service and sales workers', 'technicians, equipment, machine operation and assembly workers' and 'unemployed'. These results inform men have a higher prevalence and risk of hyperuricemia and suggest that health care policies and medical services are needed to prevent it by occupational group.

This study assesses the urine microalbumin to urine creatinine ratio (uACR) with uric acid and the association with the high-density lipoprotein cholesterol (UA/HDL-C) ratio in Korean adults. Data from the 2019 Korean National Health and Nutrition Examination Survey was procured and included 5,845 adults aged 20 years or older. Several key findings were obtained in the present study. After adjusting for the related variables (age, gender, hypertension, obesity, type 2 diabetes mellitus, and chronic kidney disease), the uACR was found to be positively associated with the quartiles of the UA/HDL-C ratio (P=0.002). Moreover, after adjusting for related variables, the odds ratio (OR) of albuminuria (uACR≥30.0 mg/g) was not significant in quartile 2 (Q2) (OR, 1.015; 95% confidence interval [CI], 0.757~1.361) and Q3 (OR, 1.090; 95% CI, 0.811~1.465) but was significantly higher in Q4 (OR, 1.416; 95% CI, 1.044~1.921) as compared to Q1 of the UA/HDL-C ratio. We conclude that since the UA/HDL-C ratio is positively associated with albuminuria in Korean adults, an increased UA/HDL-C ratio could be applied as a useful measure to assess albuminuria in Korean adults.

Objectives: This study analyzed the decline in quality of life according to age in the chronic disease patient group, quantified it as a quantitative index, and compared it by sex and chronic disease. Methods: In the 2017-2019 Korea National Health and Nutrition Examination Survey database, 11,473 adults aged 19 years or older, excluding cancer patients, were analyzed for age-specific changes in the EQ-5D Index by chronic disease. The decline in quality of life according to age in patients with chronic diseases was analyzed by linear regression analysis while controlling for general characteristics. Then, linear regression analysis was performed according to sex. Results: In the case of the control group, the quality of life decreased by 0.0004 for every 1-year increase in age(P<0.001). By chronic disease, asthma(β=0.0019, P<0.001), arthritis(β=0.0017, P=0.002), thyroid dis- ease(β=0.0016, P=0.015), dyslipidemia(β=0.0011, P=0.020), and hypertension(β=0.0009, P=0.027) mostly showed a greater decrease in quality of life than the control group. In addition, when divided into two groups by sex, hypertension(β=0.0012, P=0.029), thyroid disease(β=0.0041, P=0.038), and arthritis(β=0.0022, P<0.001) showed a significant decrease in quality of life only in male. Diabetes(β=0.0056, P=0.038), dyslipi- demia(β=0.0022, P=0.001) significantly decreased quality of life only in female. Conclusions: Chronic disease had a negative impact on patients perception of quality of life, and the more severe the pain and activity limitation due to the chronic disease, the more severe it was. It also showed different patterns according to sex. Therefore, it is necessary to allocate more medical resources and provide policy support to prevent chronic diseases, which are serious social problems.

The purposes of this study were to compare the disability prevalence and its related factors between men and women. The data used for the analysis was the National Health and Nutrition Survey, 2005, and the instrument of measuring disability was the K-ADL which had been developed by Won(2002). Chi-square test and multivariate logistic regression were used to test the gender difference. In the bivariate analyses, women had more disabilities than men among the entire elderly and the young elderly. However, there was not gender difference of disability among the old elderly. After controlling for age and other factors related to disability, no gender differences in the prevalence of disability were found. However, in the same analyses for the individual activities of daily living, men had more disabilities than women for all the activities except bathing and incontinence control. In conclusion, women's higher prevalence of disability in the univariate and bivariate analyses were spurious, because it was disappeared when other related factors to disability were controled for and women's disability became lower than men for some activities of daily living.

Purpose : Smoking is a major factor in chronic obstructive pulmonary disease (COPD), but the effect of electrical cigarette smoking on COPD development is still uncertain. This study aimed to compare the functions of airways and lungs exposed to combustible cigarettes and electrical cigarettes based on the pulmonary function test (PFT) results from the Korean National Health and Nutrition Examination Survey (NHANES). Methods : This study used data from 8,942 participants with PFT results out of 47,309 total subjects from the 6th to 8th Korean NHANES (2014-2015, 2016-2018, and 2019, respectively). Individuals with diseases such as cancer, ex-smokers, and dual tobacco users were excluded. The PFT results were analyzed according to the COPD diagnostic criteria. After adjusting for confounding variables, a complex sample generalized linear model ANOVA test was performed to investigate the association between PFT results and combustible smoker or electrical cigarette user groups. Results : In an analysis based on the obstructive ventilatory disorders (forced expiratory volume in 1 second[FEV₁]/forced vital capacity[FVC]<.7), combustible cigarette smokers showed a 3.46 times higher risk of COPD compared to non-smokers, while electrical cigarette smokers exhibited no significant difference in terms of COPD-related risks compared to non-smokers. FEV₁ showed a negative relation with combustible cigarette smokers as reported elsewhere (B=-.07, p<.001). FEV₁/FVC was negatively related to both combustible cigarette smokers (B=-.03, p<.001) and electrical cigarette smokers (B=-.02, p<.001). Conclusion : FEV₁/FVC decreases were observed in the long-term exposure to both combustible and electrical cigarettes. The lower FEV₁ in the combustible cigarette group implies the worsening of the severity of COPD, suggesting more damage to the airways and lungs in the short term. Therefore, the temporary electrical cigarettes use for the transition period in order to smoking cessation potentially aids to reduce the harmful effect of combustible cigarettes in COPD development.

Purpose : The objective of this study was to determine the major factors influencing the onset of diabetes and prediabetes and for collection of the basic data required to reduce the prevalence of diabetes and plan for administration of an effective health care system. By classifying the level of blood sugar management according to three categories: normal, prediabetes, and diabetes diagnosis, and determining the causes of diabetes in consideration of various variables, we will conduct an analysis of the main factors to be addressed for effective management of blood sugar and for preparation of basic data for use in early management. Methods : In this study, an analysis of raw data from the 8th National Health and Nutrition Examination Survey collected over a period of three years from 2019 to 2021, including 8,110 subjects in 2019, 7,359 subjects in 2020, and 7,090 subjects in 2021 was performed. A total of 22,559 subjects were aged 19 years or older, and 15,821 subjects were classified as subjects for inclusion in the final analysis. In the analysis, categorical variables were tested for difference, analysis of continuous variables using regression was performed, and analysis of influencing factors was performed using multinomial logistic analysis. Result : Significant factors related to the onset of diabetes and prediabetes included age (p<.001), marital status (p<.001), occupation (p<.001), hypertension (p<.001), dyslipidemia (p<.001), cardiovascular disease (p=.008), alcohol (p=.030) smoking (p=.005), systolic blood pressure (p<.001), diastolic blood pressure (p<.001), body mass index (p<.001) and waist circumference (p=.037), blood triglycerides (p<.001), and blood cholesterol (p<.001). Conclusion : Diabetes, a complex disease affected by a variety of diseases, requires active management from the prediabetes stage, and providing an appropriate level of medical information and services to elderly individuals without family support is considered a long-term health care system requirement in Korean society where the demographic structure is changing. In particular, determining the causes of prediabetes and development of a preventive approach to administering the health care system will be important for efficient management of diabetic patients.

The purpose of this study is to understand the effects of obesity and stress on oral disease in Korean adults by using the data of the Fifth Korea National Health and Nutrition Examination Survey. The subjects of this study are 4,627 adults at the age of 19 to 64, and the data were analyzed by using SPSS Windows ver.18.0. The results are as follows: Obesity was higher in men and the age of 40 to 64 than the other. And the group with lower education or lower income level tended to show significantly higher obesity (p<0.05). As for stress, women, the age of 19 to 39 and the subjects with higher academic career tended to indicate significantly higher stress (p<0.05). As for the effects of obesity on oral disease, there were no significant difference between body mass index (BMI) or waist-hip ratio (WHR) and oral disease but there was statistically significant difference between stress and temporomandibular joint disorder (TMD) (p<0.05). Even when the subjects with stress were obese or abdominally obese, there was no significant difference in oral disease (p>0.05). As to correlation among variables, there were correlations between BMI and WHR, stress and TMD, masticatory problems and periodontal disease or TMD (p<0.05). About the effects of general characteristics, obesity, and stress on oral disease, age was the variable influencing TMD, and age and abdominal obesity were the variables influencing masticatory problems (p<0.05). In this society, the environment surrounding individuals is fairly complex, and the concept of health including quality of life has more complex meaning than in the past. Various factors are influencing obesity and stress, and they are also influencing oral health and behaviors. Accordingly, it will be needed not only to make efforts to reduce obesity and stress but also to employ approaches from different perspectives to improve oral health.
