Objective: This cross-sectional study aimed to investigate the characteristics of malocclusions in scoliotic patients through clinical examinations. Methods: Fifty-eight patients with idiopathic scoliosis (IS) and 48 patients with congenital scoliosis (CS) participated in the study. A randomly selected group of 152 orthopedically healthy children served as the control group. Standardized orthodontic and orthopedic examination protocols were used to record the occlusal patterns and type of scoliosis. Assessments were made by three experienced orthodontists and a spinal surgery team. The differences in the frequency distribution of occlusal patterns were evaluated by the chi-squared test. Results: In comparison with patients showing IS, patients with CS showed a higher incidence of Cobb angle ≥ 45° (p = 0.020) and included a higher proportion of patients receiving surgical treatments (p < 0.001). The distribution of the Angle Class II subgroup was significantly higher in the IS (p < 0.001) and CS (p = 0.031) groups than in the control group. In comparison with the healthy controls, the CS and IS groups showed significantly higher (p < 0.05) frequencies of asymmetric molar and asymmetric canine relationships, upper and lower middle line deviations, anterior deep overbite, unilateral posterior crossbite, and canted occlusal plane, with the frequencies being especially higher in CS patients and to a lesser extent in IS patients. Conclusions: Patients with scoliosis showed a high frequency of malocclusions, which were most obvious in patients with CS.

The rating curve is required to convert measured stage into a discharge and is developed using the measurement. In the development of the rating curve, the segmentation position is determined by considering the hydraulic characteristic and channel shape, and subjective judgment of the Hydrographer may intervene in this process. The segmentation position is so important that it determines the overall form of the rating curve, and the incorrect segmentation can cause errors in the rating curve, especially in extrapolation. In order to develop an accurate rating curve with a small number of measurements, the sections must be divided by considering hydraulic characteristic such as the cross-sectional shape. In this study, hydraulic examination methods such as stage-mean velocity, stage-area, stage-${\sqrt{Q}}$ investigated and supplemented to eliminate subjectivity in segmental positioning. Appropriateness for the segmentation position was verify in consideration of the physical meaning of the rating curve index (c).

Aim: This study investigated the association between leisure activities and cognitive impairment in Korean community-dwelling older adults. Methods: Among participants of the 2017 National Survey of Older Koreans, 10,055 (male=4,277, female=5,778) were included in this cross-sectional study. To better identify the association between late-life cognition and leisure activities, individual leisure activities were categorized into 3 types including productive, consumptive, and unclassified activities. Multivariate logistic regression analysis was performed to assess the association between participation in leisure activities and cognitive impairment when controlling for possible covariates evidenced by previous studies. Results: Male participants were more likely to be cognitively impaired than female ones with significant differences in all the covariates. After controlling for confounding variables, involvement in productive leisure activities was found to be associated with cognitive function in both male and female groups, along with age, educational level, depressive symptoms, subjective hearing problems, and occupational status. Conclusion: Involvement in productive leisure activities might be associated with decreased risk of cognitive impairment in later life. Appropriate strategies to encourage older adults to participate in productive leisure activities should be established to help them maintain their cognitive function.

Purpose : This study aimed to investigate the association between asthma and oral health and factors influencing asthma in adults. We also investigated whether asthma is related to mental health and physiological factors of blood. Methods : Data from 12,639 adults was taken from the 7th period (2016~2018) Korea National Health and Nutrition Examination Survey and analyzed using with SPSS 22.0 statistical program. Statistical analysis of data included frequency analysis, cross-analysis, and logistic regression analysis. For continuous data, an independent sample t-test was performed. The statistical significance level was defined as 0.05. Results : The probability of asthma occurrence was statistically different within general characteristics (gender, age, school grade, income, and drinking). By independent variables in a logistic regression analysis, the asthma diagnosis group had more people with speech discomfort (OR=1.37), chewing discomfort (OR=1.29), and oral pain (OR=.73). We found that people with asthma had a more unfavorable perception of their health (OR=1.73), suffered more depression (OR=.45), stress (OR=.66), and limited activity (OR=2.38). Moreover, the white blood cell count (OR=1.10) and high sensitivity C-reactive protein test (OR=1.06) also showed higher values than the control group. Conclusion : Our study showed that oral health and mental health were associated with the asthma, and influencing factors were oral health and behavior and mental health-related characteristics. Therefore, it is necessary to understand asthma-related risk factors for oral health and recognize the importance of systematic oral care education and regular dental visits for patients receiving asthma treatment. Thus, this study provides valuable insights on appropriate oral health management and prevention of asthma in patients.

Background: Obesity is a major public health problem that is causally related to serious medical conditions. In this study, the public health implications of obesity based on body mass index (BMI) with anthropometric measures among adults in the Republic of Korea and Japan in 2019 were compared. Methods: A simple cross-section, nationally representative of the raw data from the National Health and Nutrition Examination Survey in 2019 between Korea and Japan were used. We analyzed the data of those categorized as obese with a BMI of ≥25 kg/m² according to the World Health Organization Expert Consultation. Results: The average values of BMI based on body height and body weight among males and females in Korea were 24.6±0.08 and 23.3±0.09, respectively; those in Japan were 23.9±0.08 and 22.6±0.08, respectively. The measured anthropometric values were obviously higher in Korean than in Japan (P<0.01). The prevalence rates (PRs) of obesity by sex in Korea were 41.4% among males and 27.3% females; those in Japan were 32.5% among males and 22.0% among females. The statistically significant results showed that the total obesity rate was higher in males than in females in both countries (P<0.01). The PRs of obesity in Korea were 41.4% in males and 27.3% in females; those in Japan were 32.5% in males and 22.0% in females. The statistically significantly PR of total obesity among Korean adults was greater than that among Japanese adults (P<0.01). Conclusion: The PR of obesity in Korea relative to that in Japan showed a gradually increasing trend. Obesity is a major problem, especially in the pilot group. Reducing the prevalence of obesity among pilots is important for reducing in-flight medical incapacitation and ensuring flight safety. Obesity management is necessary to prevent obesity-related diseases and promote pilot health.

PURPOSE: This study aimed to evaluate the correlation between executive function and gait evaluations for the elderly, and validate the obstacle gait evaluation as a cognitive impairment test tool. METHODS: This study was a cross-sectional design. 79 people aged 65 years or older were selected as subjects. The Korean version of the Mini-Mental State Examination (MMSE-KC) to evaluate overall cognitive function and the Trail Making Test (TMT) A, B to measure executive function were performed. The 4-meter walking speed test and the walking speed test while crossing over an obstacle were carried out to evaluate gait. The Spearman's correlation was used to measure the correlation between cognition and gait speed. RESULTS: There was no significant correlation between the 4 m gait speed and executive function( TMT-A (p = .056), TMT-B (p = .115)). However, there was a significant correlation between the 4 m gait speed and MMSE-KC (r = .277, p < .05). There was also a significant correlation between walking speed while crossing over an obstacle and all tests (MMSE-KC (r = .382, p < .01). TMT-A (r = -.327, p < .01), TMT-B (r = -.283, p < .05)). CONCLUSION: It was found that the gait speed while crossing over an obstacle was correlated with all cognitive function tests. Therefore, we suggest the use of the gait speed test while crossing over an obstacle rather than the simple gait test to diagnose cognitive decline.

BACKGROUND/OBJECTIVES: Although adherence to a higher diet quality may help prevent cognitive decline in older adults, literature for this in a Korean population is limited. Thus, the aim of this study was to examine the association between diet quality indices and the risk of mild cognitive impairment (MCI) in Korean older adults. SUBJECTS/METHODS: This cross-sectional study included 806 community-dwelling people aged 60 yrs and over in Korea. Diet quality was assessed via the revised Recommended Food Score (RFS) and alternate Mediterranean Diet Score (aMDS). Cognitive function was measured using a Korean version of the Mini-Mental State Examination (MMSE-KC). Associations between diet quality indices and MMSE-KC score were assessed with a general linear model after adjusting for covariates. Logistic regression was used to determine the association between diet quality indices and the risk of MCI. RESULTS: The prevalence of MCI was 35.3%. There were no significant trends between MMSE-KC scores and RFS and aMDS after adjusting for age, gender, education, exercise, living status, social activity, and alcohol drinking. Among total subjects, RFS was inversely associated with the risk of MCI after adjusting for covariates (Q5 vs. Q1; odds ratio [OR], 0.49; 95% confidence interval [CI], 0.28-0.83). Among total subjects and men, aMDS was inversely related to the risk of MCI after adjusting for covariates (Q5 vs. Q1; OR, 0.51; 95% CI, 0.29-0.89 for total subjects; Q5 vs. Q1; OR, 0.36; 95% CI, 0.15-0.83 for men). CONCLUSIONS: Our results demonstrate that high diet quality evaluated by RFS and aMDS is inversely associated with the risk of MCI. Thus, high quality diet may reduce or retard cognitive decline in the old population. Longitudinal studies are needed to determine the causal relationship between diet quality and the risk of MCI in the elderly.

Objectives: The budget gap in the health sector of local governments affects the supply of health services, which can cause the health gap. This study classified local governments according to their financial characteristics, such as local financial independence and health budget level. It analyzed the health behaviors and disease prevalence of local residents to examine the effect of local government financial investment on the health of local residents. Methods: To classify types according to the financial characteristics of local governments, financial independence and the health budget data for 17 local governments were collected from the local fiscal yearbook of the Ministry of Public Administration and Security. The prevalence of chronic diseases and healthy behavior was compared using the 16,333 data of adults between the ages of 30 and 65 years among the original data of the National Health and Nutrition Examination Survey (2016-2020). Results: Cluster analysis was used to classify local governments into five clusters according to the health financial capacity type. A comparison of the prevalence of local residents by cluster revealed a similar prevalence of hypertension, diabetes, and hypercholesterolemia. On the other hand, the obesity rate (P < 0.01), high-risk drinking rate (P < 0.01), aerobic physical activity rate (P < 0.001), and healthy eating practice rate (P < 0.001) were significantly different. In addition, an analysis of the odds ratio based on the Seoul area revealed a higher risk of health behavior of non-Seoul residents. Conclusions: It is necessary to review the universal health promotion project budget considering the degree of regional financial vulnerability from the viewpoint of health equity to narrow the health gap among regions.

The purpose of this study was to find out the relationship between the frequency of consumption of sports drinks and energy drinks and aerobic physical activity in the 6-29 year old group in the National Health and Nutrition Examination Survey. The sociodemographic characteristics, aerobic physical activity, and beverage intake of the subjects were calculated using composite sample descriptive statistics, and the mean difference between groups was analyzed by cross-tabulation, χ²-test, and binary logistic regression analysis. High-intensity aerobic activity was analyzed as an increase in the intake frequency of sports drinks(ionic drinks, vitamin drinks) and energy drinks(high-caffeine drinks) (p<0.05). Compared to moderate-intensity aerobic physical activity, high-intensity aerobic physical activity was analyzed as a factor influencing the increase in beverage intake frequency. The purpose of this study was to investigate the relationship between physical activity and beverage consumption, which is a critical issue for promoting health both now and in the future, and to developed an intervention program based on the findings. Through this study, we aimed to gather basic data that can help people live healthy lives, and raise both individual and societal awareness of the importance of making better beverage choices.
