Purposes: This study aims to identify the characteristics of the study subjects by age, including non-elderly people aged 19 to 65, pre-elderly people aged 65 to 75, and elderly people aged 75 and over, and to identify factors affecting health literacy based on an investigation of the health literacy level of each study group. This study would like to find out the differences in health literacy factors by age group. Methodology: The HLS-EU-Q16, developed by the World Health Organization Regional Office for Europe for the Health literacy Survey of Europeans, will be applied in this study. Findings: We found that scores decreased in order of nonelderly, pre-elderly, and late-elderly in health care, disease prevention, and health promotion. In addition, health literacy was lower in the older age group, and higher health literacy was associated with being unmarried, higher education, and higher income. In terms of influencing factors, marital status was significantly different in the non-elderly group, and higher education level was associated with higher health literacy. Practical Implications: The results of this study show that health literacy levels are low in all age groups, and efforts to improve health literacy in younger, older, and non-elderly groups are needed. It is expected that age-specific health literacy strategies can help improve the level of understanding and utilization of health information, improve health, and lead a healthy life.

Background: The aim of this study was to assess correlation between pain and degenerative bony changes on cone-beam computed tomography (CBCT) images of temporomandibular joints (TMJs). Methods: Two hundred eighty-three temporomandibular joints with degenerative bony changes were evaluated. Pain intensity (numeric rating scale, NRS) and pain duration in patients with degenerative joint disease (DJD) were also analyzed. We classified condylar bony changes on CBCT into five types: osteophyte (Osp), erosion (Ero), flattening (Fla), subchondral sclerosis (Scl), and pseudocyst (Pse). Results: Degenerative bony changes were the most frequent in the age groups of 10~19, 20-29, and 50~59 years. The most frequent pain intensity was "none" (NRS 0, 34.6%) followed by "annoying" (NRS 3-5, 29.7%). The most frequent condylar bony change was Fla (219 joints, 77.4%) followed by Ero (169 joints, 59.7%). "Ero + Fla" was the most common combination of the bony changes (12.7%). The frequency of erosion was directly proportional to NRS, but the frequency of osteophyte was inversely proportional. The prevalence of Ero increased from onset until 2 years and gradually decreased thereafter. The prevalence of Osp, Ero, and Pse increased with age. Conclusions: Osp and Ero can be pain-related variables in degenerative joint disease (DJD) patients. "Six months to 2 years" may be a meaningful time point from the active, unstable phase to the stabilized late phase of DJD.

Background: Studies on the risk of mercury (Hg) in Korean fishery products focus primarily on total Hg levels as opposed to methylmercury (MeHg) levels. None of the few studies on MeHg in tuna investigated tuna from Japanese restaurants. Few have evaluated lead (Pb), cadmium (Cd) and arsenic (As) in tuna. Thus, this study aimed to conduct a risk assessment by evaluating heavy metal concentrations in tuna from Japanese restaurants. Methods: Thirty-one tuna samples were collected from Japanese restaurants in the Republic of Korea. They were classified according to region and species. The concentration of heavy metals in the samples was analyzed using the Ministry of Food and Drug Safety Food Code method. The rate of exceedance of maximum residue levels (MRLs) and the risk compared to the provisional tolerable weekly intake (PTWI) set by the Joint Food and Agriculture Organization/World Health Organization Expert Committee on Food Additives (%PTWI) were evaluated for risk assessment. Results: The mean of MeHg, Pb, Cd and As concentrations were 0.56 ± 1.47 mg/kg, 33.95 ± 3.74 ㎍/kg, 14.25 ± 2.19 ㎍/kg and 1.46 ± 1.89 mg/kg, respectively. No sample exceeded the MRLs of Pb and Cd, but 9.7% of the samples exceeded the MRL of MeHg. The %PTWIs of MeHg, Pb, Cd and As were 4.2037, 0.0162, 0.0244 and 1.1627, respectively. The %PTWI of MeHg by age group and sex was highest among men aged 19-29 years (10.6494), followed by men aged 30-49 years (7.2458) and women aged 19-29 years (4.8307). Conclusions: We found that 3 out of 31 samples exceeded the MRL of MeHg. The %PTWI of MeHg showed significant differences based on age and sex, and the value was likely to exceed a safe level depending on individuals' eating behaviors. Therefore, improved risk management for MeHg is required.

Ultrasonographic diagnosis of kidney and urinary bladder disease was performed in native Korea cattle. Ultrasonogaphic appearence of kidney and urinaryy baldder according to the growth were determined from 6 to 13 months by monthly examinations in 9 native Korean cattle. The kidney and urinary bladder were examined in standing position. The position, dimension, and structure of both kidneys were determined at 12 intercostal space and paralumbar fossa by use of ultrasonography. Ultrasonograms were obtained with 3.5 or 5.0-MHz sector transducer. The width and depth of the kidney, and the diameter of renal parenchyma and renal sinus were observed. Both kidneys were observedfrom the body surface until 8 months old age, but over the 9 months old age, only right kidney was easily accessible. The width of right kidney at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 5.7, 6.3, 6.9, 7.6, 8.4, 9.3, 9.8 and 10.7 cm, respectively. The depth 5.8, 6.1 and 6.6 cm, respectively. The size of left kidney was similar to right kidney until 8 months old age. After the 9 months old age, only right kidney was easily accessible. The circumference of urinary bladder at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 19.1, 21.7, 22.5, 23.0, 24.2, 25.3, 27.8 and 29.1 cm, respectively. Calculi in urinary bladder were observed by ultrasonography.

Background and Objectives In this study, we evaluated differences in the prevalence of allergic rhinitis, asthma, atopic dermatitis and specific immunoglobuline E (IgE) value for some respiratory antigens in Korean adults. Subjects and Method The study was conducted using data from the 5th National Health and Nutrition Survey (2010-2012). All subjects who were aged 19 years or older completed questionnaires on asthma, atopic dermatitis and allergic rhinitis. The subjects were first divided into male and female, and then into age groups of 19-29, 30-39, 40-49, 50-59, 60-69, ${\geq}70$ each. The lifetime and current prevalence rates for allergic rhinitis, asthma, and atopic dermatitis were calculated for each age group. The total and specific IgE level for Dermatophagoides farinae (DF), cockroach, and dog dander were also calculated. Results Final participants of 17542 were analyzed for the prevalence rate among the total of 25534 participants. The mean IgE level was calculated from 2028 subjects from the final participants. In asthma, the lifetime prevalence and current prevalence increased with age, but decreased with atopic dermatitis and allergic rhinitis. Total IgE level increased with age, but IgE level of DF reached its peak at 20-29 years, and then decreased rapidly thereafter. There was no clear trend for cockroach and dog dander. Conclusion The prevalence of allergic diseases in adults varies widely by age group. Asthma has a low prevalence after age 20 and gradually increases after age 50. Atopic dermatitis and allergic rhinitis are the most prevalent in their 20s and gradually decrease thereafter.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic led to increased mortality rates. To assess this impact, this ecological study aimed to estimate the excess death counts in southern Iran. Methods: The study obtained weekly death counts by linking the National Death Registry and Medical Care Monitoring Center repositories. The P-score was initially estimated using a simple method that involved calculating the difference between the observed and expected death counts. The interrupted time series analysis was then used to calculate the mean relative risk (RR) of death during the first year of the pandemic. Results: Our study found that there were 5571 excess deaths from all causes (P-score=33.29%) during the first year of the COVID-19 pandemic, with 48.03% of these deaths directly related to COVID-19. The pandemic was found to increase the risk of death from all causes (RR, 1.26; 95% confidence interval [CI], 1.19 to 1.33), as well as in specific age groups such as those aged 35-49 (RR, 1.21; 95% CI, 1.12 to 1.32), 50-64 (RR, 1.38; 95% CI, 1.28 to 1.49), and ≥65 (RR, 1.29; 95% CI, 1.12 to 1.32) years old. Furthermore, there was an increased risk of death from cardiovascular diseases (RR, 1.17; 95% CI, 1.11 to 1.22). Conclusions: There was a 26% increase in the death count in southern Iran during the COVID-19 pandemic. More than half of these excess deaths were not directly related to COVID-19, but rather other causes, with cardiovascular diseases being a major contributor.
