ABSTRACT

Abstract During the first half of the twentieth century, Western psychiatry was quickly absorbed in Japan, particularly the versions from Germany and Austria. By 1940, over 130 psychiatric hospitals were caring for approximately thirty thousand patients in cities, while in rural areas about sixty thousand people still depended on family members for care. Japan's empire expanded during this same period, and many immigrants came to the country. Growth in immigration from Korea was particularly important. Korean immigrants encountered Japanese psychiatric hospitals during the second quarter of the twentieth century, and this paper examines the complex nature of their hospital stays.


Resumo Ao longo da primeira metade do século XX, a psiquiatria ocidental foi rapidamente absorvida no Japão, particularmente as versões advindas da Alemanha e da Áustria. Em 1940, mais de 130 hospitais psiquiátricos cuidavam de cerca de trinta mil pacientes nas cidades, enquanto nas áreas rurais cerca de sessenta mil pessoas ainda dependiam dos cuidados de familiares. No mesmo período, o império japonês expandiu-se, e muitos imigrantes vieram para o país. Particularmente importante foi o crescimento da imigração coreana. Hospitais psiquiátricos japoneses e imigrantes coreanos se encontraram no segundo quartel do século XX. O artigo examina a complexidade dessas estadas hospitalares.

ABSTRACT

SUMMARY: Metopic suture can be visualized from the nasion to the bregma along the arch of the frontal bone in mid-sagittal plane. Persistent metopic suture normally closing between 1st and 2nd year of life has also been related with ethnicity. The present study reports the presence of complete and incomplete metopic sutures in Nepalese and Korean population skulls which helps to shed light on its incidence rate. Out of 121 adult skulls in Nepalese population, metopic suture was found to be present in 33 skulls. Incomplete metopic sutures showed variations of morphology, like linear (6.61 %), V-shaped (8.26 %) and double incomplete (10.74 %) and two cases with complete metopic suture, which showed variation in interdigitation between its anterior and posterior ends. Korean population showed metopic suture to be present in 8 skulls out of 104 with metopism in 3 skulls. Incomplete metopic sutures like double incomplete (1.92 %) and linear (2.88 %) were also noted. Alterations to local strains could be the contributing factor for such variation and complexity of interdigitation, which occur during the growth of the braincase. The knowledge of the metopic suture and its variations according to ethnicity is important and should be considered to prevent wrong diagnosis. The presence of different types of metopic sutures as reported by the present study provides informative value on the presence and variation of such sutures in population depending on ethnicity and ought to be helpful in diagnostic sequences in emergency setting.


RESUMEN: La sutura metópica se puede visualizar desde nasión hasta el bregma a lo largo del arco del hueso frontal en el plano mediano sagital. La sutura metópica persistente que normalmente se cierra entre el primer y segundo año de vida, también se ha relacionado con el origen étnico. El presente estudio informa la presencia de suturas metópicas completas e incompletas en los cráneos de la población nepalesa y coreana, lo que además de entregar información sobre su tasa de incidencia. De 121 cráneos adultos en la población nepalesa, en 33 de ellos se encontró la sutura metópica. Las suturas metópicas incompletas mostraron variaciones de la morfología, como lineal (6,61 %), en forma de V (8,26 %) y doble incompleta (10,74 %), además de dos casos con sutura metópica completa, que mostraron variación en la interdigitación entre sus extremos anterior y posterior. De los 104 cráneos de la población coreana en 8 se presentó la sutura metópica y en 3 metopismo. También se observaron suturas metópicas incompletas como doble incompleta (1,92 %) y lineal (2,88 %). Las alteraciones en las etnias locales podrían ser el factor contribuyente para tal variación y complejidad de la interdigitación, que ocurre durante el crecimiento de la cráneo. El conocimiento de la sutura metópica y sus variaciones según el origen étnico es importante y debe considerarse para prevenir un diagnóstico incorrecto. La presencia de diferentes tipos de suturas metópicas según lo informado en el estudio, proporciona un valor informativo sobre la presencia y la variación de tales suturas en la población, dependiendo de la etnia, y debería ser útil en las secuencias de diagnóstico en situaciones de emergencia.

ABSTRACT

OBJECTIVE: This study presents a preliminary report on the chest radiographic and computed tomography (CT) findings of the 2019 novel coronavirus disease (COVID-19) pneumonia in Korea.MATERIALS AND METHODS: As part of a multi-institutional collaboration coordinated by the Korean Society of Thoracic Radiology, we collected nine patients with COVID-19 infections who had undergone chest radiography and CT scans. We analyzed the radiographic and CT findings of COVID-19 pneumonia at baseline. Fisher's exact test was used to compare CT findings depending on the shape of pulmonary lesions.RESULTS: Three of the nine patients (33.3%) had parenchymal abnormalities detected by chest radiography, and most of the abnormalities were peripheral consolidations. Chest CT images showed bilateral involvement in eight of the nine patients, and a unilobar reversed halo sign in the other patient. In total, 77 pulmonary lesions were found, including patchy lesions (39%), large confluent lesions (13%), and small nodular lesions (48%). The peripheral and posterior lung fields were involved in 78% and 67% of the lesions, respectively. The lesions were typically ill-defined and were composed of mixed ground-glass opacities and consolidation or pure ground-glass opacities. Patchy to confluent lesions were primarily distributed in the lower lobes (p = 0.040) and along the pleura (p < 0.001), whereas nodular lesions were primarily distributed along the bronchovascular bundles (p = 0.006).CONCLUSION: COVID-19 pneumonia in Korea primarily manifested as pure to mixed ground-glass opacities with a patchy to confluent or nodular shape in the bilateral peripheral posterior lungs. A considerable proportion of patients with COVID-19 pneumonia had normal chest radiographs.

ABSTRACT

BACKGROUND AND OBJECTIVES: Although dietary management is strongly recommended in patients with hypertension, little is known about how many manage their diet and follow the guidelines for hypertension. We investigated the prevalence of dietary management among adults with known hypertension and evaluated their compliance to the dietary guidelines.METHODS: Data from the Korea National Health and Nutrition Examination Survey 2013–2016 were used. Among 15,870 adults aged 30–79 years, 4,162 reported a physician-diagnosed hypertension. Diet management behavior was defined by self-report response. Actual dietary intake was assessed by a 24-hour dietary recall. Dietary quality was evaluated using the Korean Healthy Eating Index (KHEI).RESULTS: Among adults with hypertension, 28.0% reported that they were managing their diet. Those with hypertension consumed significantly less dietary sodium (p value<0.01), but also less potassium (p value<0.01), resulting in no difference of sodium-to-potassium ratio compared to those without hypertension (p value=0.66). Among those with hypertension, diet-managing adults had better KHEI score (66.9, p value<0.01) and consumed less sodium (3,354.3 mg, p value<0.01) than not-managing adults (63.6 score and 3,554.5 mg, respectively). However, total KHEI score was rather lower in those with hypertension (p value<0.01) than those without hypertension and their sodium intake was still over the recommended amount.CONCLUSIONS: More than two-thirds of Korean adults with hypertension did not manage their diet in daily life. More effective strategies are needed to increase the level of compliance with dietary recommendations for people with high blood pressure.

ABSTRACT

Porcine respiratory disease complex (PRDC) continues to be a significant economic problem to the swine industry. Porcine circovirus type 2 (PCV2), porcine reproductive and respiratory syndrome virus (PRRSV), and Mycoplasma hyopneumoniae (MH) are considered to be the most important pathogens that cause PRDC. In this study, we investigated the prevalence of antibodies against PRRSV and MH in the serum of sows and piglets from 89 domestic commercial pig farms by ELISA, and the presence of viral nucleic acids of PRRSV, including North American and European PRRS, and PCV2 was also investigated in the serum of sows and piglets from 89 domestic commercial pig farms by real-time PCR. In case of PRRSV, 78.7% (70/89) of sows were positive for PRRSV antibody, and 96.6% (86/89) of piglets were positive for PRRSV antibody. For MH, 76.4% (68/89) of sows showed positive for MH antibody. In the PRRSV viral nucleic acid detection experiment, 36.0% (32/89) of sows were positive for PRRSV nucleic acids, and virus nucleic acid was detected in 83.1% (74/89) of piglets. In case of virus type, both North American and European types were detected. In case of PCV2, 15.7% (14/89) of sows were positive for PCV2 nucleic acids. Conclusively, PCV2, PRRSV, and MH were widely distributed in pig farms in Korea. These prevalence data related with PRDC provides clinical information for vaccination strategy and development for the control of PRDC.

ABSTRACT

In 2017, the first Korean nationwide data on serum thyroid stimulating hormone (TSH) levels, serum free thyroxine (fT4) levels, and urinary iodine concentration (UIC) were published based on a population of 7,061 Koreans who participated in the Korea National Health and Nutrition Examination Survey VI. The mean TSH level was 2.16 mIU/L, with a reference interval of 0.59 to 7.03 mIU/L (men 2.09 mIU/L, women 2.24 mIU/L, P<0.001). A U-shaped association was found between serum TSH levels and age. The mean fT4 level was 1.25 ng/dL, and its reference interval was 0.92 to 1.60 ng/dL (men 1.29 ng/dL, women 1.20 ng/dL, P<0.0001). Serum fT4 levels decreased with age (P for trend <0.0001). Serum thyroid peroxidase antibody (TPOAb) was detected in 7.30% of participants (men 4.33%, women 10.62%). TPOAb titers tended to increase with age, and were higher in women than in men. The median UIC was 294 µg/L, and UIC showed a U-shaped relationship with age. According to the World Health Organization recommendations, only 23% of participants were in the adequate range of iodine intake, while 65% were in the above requirements or excessive, and 12% in insufficient. The prevalence of overt hyperthyroidism and hypothyroidism in Koreans was 0.34% to 0.54% and 0.73% to 1.43%, respectively.

ABSTRACT

The increased incidence of thyroid cancer is a worldwide phenomenon; however, the issue of overdiagnosis has been most prominent in South Korea. The age-standardized mortality rate of thyroid cancer in Korea steeply increased from 1985 to 2004 (from 0.17 per 100,000 to 0.85 per 100,000), and then decreased until 2015 to 0.42 per 100,000, suggesting that early detection reduced mortality. However, early detection of thyroid cancer may be cost-ineffective, considering its very high prevalence and indolent course. Therefore, risk stratification and tailored management are vitally important, but many prognostic markers can only be evaluated postoperatively. Discovery of preoperative marker(s), especially for small cancers, is the most important unmet clinical need for thyroid cancer. Herein, we discuss some such factors that we recently discovered. Another unmet clinical need is better treatment of radioiodine-refractory (RAIR) differentiated thyroid cancer (DTC) and undifferentiated cancers. Although sorafenib and lenvatinib are available, better drugs are needed. We found that phosphoglycerate dehydrogenase, a critical enzyme for serine biosynthesis, could be a novel therapeutic target, and that the lymphocyte-to-monocyte ratio is a prognostic marker of survival in patients with anaplastic thyroid carcinoma or RAIR DTC. Deeper insights are needed into tumor-host interactions in thyroid cancer to improve treatment.

ABSTRACT

Korea is currently an aged society and is on the cusp of becoming a superaged society in a few years. The health burden of cardiovascular diseases increases with age, and the increasing prevalence of cardiovascular risk factors, such as obesity, hypertension, diabetes mellitus, and dyslipidemia, may be linked to increased population-level cardiovascular risk. In 2018, the prevalence of obesity in Korea was 35.7% (men, 45.4%; women, 26.5%) according to the Obesity Fact Sheet 2019, based on National Health Insurance Corporation medical checkup data. In 2016, the prevalence of diabetes was 14.4% in Koreans older than 30 years according to the Diabetes Fact Sheet published by the Korean Diabetes Association, based on data from the Korean National Health and Nutrition Examination Survey. The prevalence of hypertension in the total population of Korea in 2018 was 28.3% according to the Korean Hypertension Fact Sheet produced by the Korean Society of Hypertension. Lastly, the prevalence of dyslipidemia in 2018 was 40.5% according to the Dyslipidemia Fact Sheet published by the Korean Society of Lipid and Atherosclerosis. In this article, I would like to review the prevalence and current management of cardiovascular risk factors in Korea according to the fact sheets released by various associations.

ABSTRACT

BACKGROUND: Studies on the relationship between thyroid function and anemia in the euthyroid range are scarce. We aimed to evaluate the association between anemia and serum free thyroxine (fT4) and thyrotropin (TSH) in euthyroid adults.METHODS: Data on 5,352 participants aged ≥19 years were obtained from the Korea National Health and Nutrition Examination Survey VI (2013 to 2015). Anemia was defined as hemoglobin (Hb) <13 and <12 g/dL for men and women, respectively.RESULTS: Overall, 6.1% of participants had anemia, and more women (9.9%) had anemia than men (2.8%, P<0.001). In multivariate analysis, serum fT4 levels, but not TSH, were positively associated with serum Hb levels in both sexes (P<0.001, each). Serum Hb levels linearly reduced across decreasing serum fT4 quartile groups in both sexes (P<0.001, each). After adjusting for potential confounding factors, participants with low-normal fT4 had 4.4 (P=0.003) and 2.8 times (P<0.001) higher risk for anemia than those with high-normal fT4 among men and women, respectively. When participants were divided into two groups at 50 years of age, in younger participants, men and women with the first quartile were at higher risk of anemia than men with the second quartile (odds ratio [OR], 3.3; P=0.029) and women with the forth quartile (OR, 3.2; P<0.001), respectively. This association was not observed in older participants.CONCLUSION: These results suggest that a low-normal level of serum fT4 was associated with a lower serum Hb level and a higher risk of anemia in euthyroid adults, especially in younger participants.

ABSTRACT

BACKGROUND: Pheochromocytomas and paragangliomas (PPGLs) are rare endocrine tumors originating from chromaffin cells. PPGLs are associated with a high mortality rate and several complications. To date, no epidemiological studies have been conducted on PPGLs in Asia. This study aimed to investigate the epidemiology and prognosis of PPGLs in Korea using nationwide data.METHODS: Using the National Health Insurance Service Database, subjects with a principal diagnosis of PPGLs on two or more occasions between 2003 and 2014 who satisfied the operational definition of PPGLs were included. Incidence, prevalence, complications, metastasis, and mortality were investigated.RESULTS: In total, 1048 subjects with a mean age of 47.6±16.1 years were included. There was no sex preponderance. The overall prevalence of PPGLs was 2.13 per 100,000 persons, and the overall age-standardized incidence rate was 0.18 per 100,000 person-years. Malignant PPGLs accounted for 17.7% (185 of 1,048) of cases, and 94 subjects exhibited metastasis at the time of diagnosis. Among initially non-metastatic PPGLs, 9.5% (nine of 954) eventually metastasized after a mean duration of 78.1±41.4 months. The 5-year survival rates for non-metastatic and metastatic PPGLs at diagnosis were 97% and 84%, respectively. Multivariable Cox regression models adjusted for covariates showed that metastatic PPGLs were associated with a 2.40-fold higher risk of mortality than non-metastatic PPGLs (95% confidence interval, 1.38 to 4.17; P=0.002).CONCLUSION: PPGLs are rare in Korea, and the prognosis of these endocrine tumors varies depending on whether they are benign or malignant. This epidemiological study paves the way for further research on PPGLs.

ABSTRACT

BACKGROUND: Rapid and accurate detection of Mycobacterium tuberculosis (MTB) is of primary importance for infection control and selection of anti-tuberculosis drugs. However, most clinical laboratories report MTB complex (MTC) without reporting MTB because MTC comprising MTB, Mycobacterium bovis, Mycobacterium africanum, Mycobacterium microti, Mycobacterium caprae and Mycobacterium pinnipedii have 99.9% similarity at the nucleotide level and identical 16S rRNA sequences. This study was conducted to analyze the species frequency of MTC isolates obtained from clinical specimen.METHODS: Of 310 MTC isolates obtained from clinical samples in a tertiary care hospital from February 2017 to August 2018, MolecuTech Real TB-Taq (YD Diagnostics, Korea) real-time PCR was performed, specifically to detect MTB. For DNA showing MTB negative results by MTB-specific real-time PCR or pyrazinamide-resistant strains, PCR-based MTC typing, spoligotyping, and exact tandem repeat D gene sequencing were performed.RESULTS: All the 310 MTC isolates were identified to be MTB. Two MTB strains of East-African-Indian 4-Vietnam genotype, which have not been reported in Korea, were also found.CONCLUSION: There was no zoonotic tuberculosis in this study. Since we investigated only 310 MTC isolates detected in only one medical institution, multi-center study is needed to accurately know the prevalence of zoonotic tuberculosis in Korea.

ABSTRACT

BACKGROUND: The weather has well-documented effects on infectious disease and reports suggest that summer peaks in the incidences of gram-negative bacterial infections among hospitalized patients. We evaluated how season and temperature changes affect bloodstream infection (BSI) incidences of major pathogens to understand BSI trends with an emphasis on acquisition sites.METHODS: Incidence rates of BSIs by Staphylococcus aureus, Enterococcus spp., Escherichia coli, Klebsiella pneumoniae, Acinetobacter spp., and Pseudomonas aeruginosa were retrospectively analyzed from blood cultures during 2008–2016 at a university hospital in Seoul, Korea according to the acquisition sites. Warm months (June–September) had an average temperature of ≥20℃ and cold months (December–February) had an average temperature of ≤5℃.RESULTS: We analyzed 18,047 cases, where 43% were with community-onset BSI. E. coli (N = 5,365) was the most common pathogen, followed by Enterococcus spp. (N = 3,980), S. aureus (N = 3,075), K. pneumoniae (N = 3,043), Acinetobacter spp. (N = 1,657), and P. aeruginosa (N = 927). The incidence of hospital-acquired BSI by Enterococcus spp. was weakly correlated with temperature, and the median incidence was higher during cold months. The incidence of community-onset BSI by E. coli was higher in warm months and was weakly correlated with temperature.CONCLUSION: We found seasonal or temperature-associated variation in some species-associated BSIs. This could be a useful information for enhancing infection control and public health policies by taking season or climate into consideration.

ABSTRACT

PURPOSE: Metabolic syndrome (MetS) is a major public health problem related to increased risks of cardiovascular disease and type 2 diabetes. We investigated whether recommended levels of leisure time physical activity (LTPA) decrease the risk of MetS in a community-based prospective cohort study (Ansung and Ansan cohort).MATERIALS AND METHODS: A total of 3910 adults (1890 men, 2020 women) without MetS examined in 2001–2002 (baseline) were included in this study and followed up from 2013 to 2014. We measured LTPA energy expenditure using the standard metabolic equivalent value [metabolic equivalent of task (MET)-h/wk]. Individuals were categorized into five groups (physically inactive, 0.1 to <7.5, 7.5 to <15.0, 15.0 to <22.5, 22.5 to <40.0, and ≥40.0 MET-h/wk).RESULTS: The mean follow-up period was 11.8 years. Among the cohort, 482 men (25.5%) and 541 women (26.8%) were diagnosed with newly developed MetS. Multivariate logistic analysis revealed a 4.4% lower MetS risk among those performing two to three times the recommended minimum of 7.5 MET-h/wk [multivariate relative risk (RR), 0.956; 95% confidence interval (CI), 0.654–1.398] and a 21.9% lower risk among those performing three to four times the physical activity minimum (multivariate RR, 0.781; 95% CI, 0.574–1.063). This association was only significant in females performing three to four times the minimum (crude RR, 0.655; 95% CI, 0.432–0.994).CONCLUSION: We noted that physical activity at more than 2 times the recommended minimum prevents MetS. Healthcare professionals should encourage inactive adults to be physically active during their leisure time to take advantage of its health benefits.

ABSTRACT

PURPOSE: This study was designed to provide a basis for building a master plan for a regional trauma system by analyzing the distribution of trauma deaths in the most populous province in Korea.MATERIALS AND METHODS: We investigated the time distribution to death for trauma patients who died between January and December 2017. The time distribution to death was categorized into four groups (within a day, within a week, within a month, and over a month). Additionally, the distribution of deaths within 24 hours was further analyzed. We also reviewed the distribution of deaths according to the cause of death and mechanism of injury.RESULTS: Of the 1546 trauma deaths, 328 cases were included in the final study population. Patients who died within a day were the most prevalent (40.9%). Of those who died within a day, the cases within an hour accounted for 40.3% of the highest proportion. The majority of trauma deaths within 4 hours were caused by traffic-related accidents (60.4%). The deaths caused by bleeding and central nervous system injuries accounted for most (70.1%) of the early deaths, whereas multi-organ dysfunction syndrome/sepsis had the highest ratio (69.7%) in the late deaths. Statistically significant differences were found in time distribution according to the mechanism of injury and cause of death (p<0.001).CONCLUSION: The distribution of overall timing of death was shown to follow a bimodal pattern rather than a trimodal model in Korea. Based on our findings, a suitable and modified trauma system must be developed.

ABSTRACT

PURPOSE: We aimed to analyze the surveillance reports of adverse events (AEs) due to different types of pneumococcal vaccines, in addition to detecting and validating signals of pneumococcal vaccines by comparing AEs with labels.MATERIALS AND METHODS: We analyzed the percentages of AEs according to vaccine type [pneumococcal polysaccharide vaccines (PPSVs) and pneumococcal conjugate vaccines (PCVs)] in children and adults using data from the Korea Adverse Event Reporting System (KAERS) database from 2005 to 2016. A signal was defined as an AE that met all three indices of data mining: proportional reporting ratio (PRR), reporting odds ratio (ROR), and information component (IC). We validated the detected signals by calculating sensitivity, specificity, as well as positive and negative predictive values of the signals against label information.RESULTS: Of the 39933 AE reports on vaccination, 5718 (7.0%) were related to pneumococcal vaccine. The most frequent AE after vaccination with PPSV was fever (23.9%) in children and injection-site reaction in adults. The most frequent AE after vaccination with PCV in children was pharyngitis (26.2%). In total, 13 AEs met all three indices for signal detection. Among these, hypotension, apathy, sepsis, and increased serum glutamic oxaloacetic transaminase level were not listed on vaccine labels. In validation analysis, PRR and ROR performed slightly better than IC for adults who were vaccinated with PPSVs.CONCLUSION: Overall, 13 new signals of PPSVs, including four signals not listed on the labels, were detected. Further research based on additional AE reports is required to confirm the validity of these signals for children.

ABSTRACT

PURPOSE: This study aimed to evaluate the validity of the Western Ontario and McMaster Universities Arthritis Index Short Form (WOMAC-SF) for the assessment of musculoskeletal disorders. We evaluated whether WOMAC-SF correlated with the World Health Organization Disability Assessment Schedule 12 (WHODAS-12) and Kaigo-Yobo questionnaires for assessing health-outcomes in Korea.MATERIALS AND METHODS: This cross-sectional study used data from the Namgaram-2 cohort. WOMAC, WOMAC-SF, WHODAS-12, and Kaigo-Yobo questionnaires were administered to patients with musculoskeletal disorders, including radiology-confirmed knee osteoarthritis (RKOA), sarcopenia, and osteoporosis. The relationships among WOMAC-SF, WHODAS-12, and Kaigo-Yobo scores were analyzed by stepwise multiple regression analysis.RESULTS: WOMAC-SF was associated with the WOMAC questionnaire. The results of confirmatory factor analysis for the hypothesized model with two latent factors, pain and function, provided satisfactory fit indices. WOMAC-SF pain and function were associated with RKOA. Kaigo-Yobo was associated with WOMAC-SF pain (B=0.140, p=0.001) and WOMAC-SF function (B=0.042, p=0.004). WHODAS-12 was associated with WOMAC-SF pain (B=0.679, p=0.003) and WOMAC-SF function (B=0.804, p<0.001).CONCLUSION: WOMAC-SF was validated for the evaluation of low extremity musculoskeletal disorders and health-related quality of life in a community-based population. Furthermore, we confirmed that WOMAC-SF were reflective of disability and frailty, which affect health outcomes.

ABSTRACT

Research on physical activity and health is actively being conducted. In the Korea National Health and Nutrition Examination Survey (KNHANES), the Global Physical Activity Questionnaire (GPAQ) was newly introduced in 2014. The purpose of this study was to investigate the levels of physical activity and related factors in Koreans who were assessed through the GPAQ by dividing the physical activity by occupation, leisure, and transport domain. This study used data from the KNHANES (2014–2016), the study population of which included 17,357 participants aged 12 to 80 years. We compared the differences in physical activity by sociodemographic factors, health-related factors, and psychological health-related factors. Moreover, we also compared the mean metabolic equivalent of task and daily sitting time according to physical activity domain by sex and age group. Finally, we investigated the sociodemographic factors, health-related factors, and psychological health-related factors that significantly affect the average physical activity per week. The various factors were found to differ in the frequency of physical activity levels. In addition, there was a difference in the amount of physical activity per occupation, leisure, and transport domain in each age group. Finally, age, sex, high-density lipoprotein cholesterol levels, arthritis, allergic rhinitis and sinusitis, sleeping time, and perceived health status significantly affected physical activity. The levels of physical activity significantly differed by sociodemographic factors, health-related factors, and psychological health-related factors. There was also a difference in the physical activity levels according to the age and sex per each domain of physical activity.

ABSTRACT

PURPOSE: The main purpose of this study was to compare the relationships between physical activity (measured using an accelerometer vs. self-reported) and cardiovascular disease risk factors. Differences in accelerometry physical activity between 10-minute bouts and total bouts were also compared.METHODS: Data originated from the Korea National Health and Nutrition Examination Survey. Logistic regression was used to predict cardiovascular disease risk from physical activity levels.RESULTS: Self-reported physical activity could not significantly predict the odds of having cardiovascular risk. However, the insufficiently active group classified according to the total-bout physical activity had significantly greater odds of having hypertension or prehypertension (odds ratio [OR], 1.35; 95% confidence interval [95% CI], 1.00–1.82), diabetes mellitus (OR, 1.77; 95% CI, 1.01–3.19), and dyslipidemia (OR, 1.65; 95% CI, 1.17–2.36) than the highly active group. Regarding the 10-minute bout physical activity, the inactive group had significantly greater odds of having only hypertension or prehypertension (OR, 1.67; 95% CI, 1.02–2.76) than the highly active group.CONCLUSION: Total-bout physical activity measured using an accelerometer could significantly predict the cardiovascular disease risk compared to 10-minute bout physical activity. However, self-reported physical activity could not significantly predict the cardiovascular disease risk.

ABSTRACT

OBJECTIVES: This study aimed to compare customers' perceptions of the need for a low-sodium diet and sodium-reduced operations in the industry foodservice by age. The relationships between health concerns and perceptions of the need for sodium-reduced operations and low-sodium diets in the industry foodservice were analyzed.METHODS: A survey was conducted among 340 industry foodservice customers aged 20–50 years and residing in Seoul, Korea. This study investigated the respondents' health concerns, their perception of the need for sodium-reduced foodservice operations, their perception of a sodium-reduced diet, and the general details of the foodservices they used. A cross-tabulation analysis and ANOVA were performed to identify differences in measurement items by age, and a simple regression analysis was performed to examine relationships between measurement items.RESULTS: For the customers' perception of the need for a sodium-reduced foodservice operation, the item “it is necessary to provide separate spices and sauces to reduce sodium intake” achieved the highest score (3.88 points out of a possible 5 points). For the perception of a sodium-reduced diet, the item “I think it is helpful for one's health” obtained the highest score (4.13 points). Respondents' health concerns had a positive effect on increasing the level of perception of the need for sodium-reduced foodservice operations and that of a sodium-reduced diet.CONCLUSIONS: Foodservice nutritionists could help enhance their customers' perceptions of the needs for sodium-reduced foodservice operations and sodium-reduced diets by frequently providing them with sodium-related health information.
