Purpose: This study was conducted to identify differences in health behavior, health-related quality of life, and depression between adult men and women during the COVID-19 pandemic. Methods: Data were obtained from 1,927 men and 2,314 women aged 19 to 64 who participated in the 7th Korea National Health and Nutrition Survey in 2020. Data were analyzed using complex sample x² test, complex sample general linear model, and complex sample logistic regression. Results: During the pandemic, men drank more alcohol (OR=2.34, 95% CI: 1.89~2.91) and smoked more (OR=7.89, 95% CI: 6.16~10.09) than women. In addition, men were 2.45 times more exposed to second-hand smoke at the workplace (95% CI: 1.78~3.37) and 1.4 times more exposed in public places (95% CI: 1.12~1.77). The rate of muscle exercise was higher among men than women (OR=2.09, 95% CI: 1.76~2.49). No difference in health-related quality of life was observed between men and women (t=0.17, p=.78), but women had higher depression scores (t=-3.14, p=.002). Conclusion: Customized sex-specific interventions should be developed during the COVID-19 pandemic. This kind of infectious disease disaster requires plans designed to reduce alcohol intake and smoking among men and interventions aimed at increasing muscle exercise among women. Strategies should also be formulated to reduce depression among women.

Background: Tobacco is consumed in both smoking and smokeless forms in India. About 35-40% of tobacco consumption in India is in the latter. The study objective was to describe the association between chewing tobacco and adult mortality. Materials and Methods: A case-control study was conducted in urban (Chennai city) and rural (Villupuram district) areas in Tamil Nadu state in South India. Interviewed in 1998-2000 about 80,000 families (48,000 urban and 32,000 rural) with members who had died during 1995-1998. These were the cases and their probable underlying cause of death was arrived at by verbal autopsy. Controls were 600,000 (500,000 urban, 100,000 rural) individuals from a survey conducted during 1998-2001 in the same two study areas from where cases were included. Results: Mortality analyses were restricted to non-smoking non-drinkers aged 35-69. The age, sex, education and study area adjusted mortality odds ratio was 30% higher (RR:1.3, 95%CI:1.2-1.4) in ever tobacco chewers compared to never chewers and was significant for deaths from respiratory diseases combined (RR:1.5, 95%CI:1.4-1.7), respiratory tuberculosis (RR:1.7, 95%CI:1.5-1.9), cancers all sites combined (RR:1.5, 95%CI:1.4-1.7) and stroke (RR:1.4, 95%CI:1.2-1.6). Of the cancers, the adjusted mortality odds ratio was significant for upper aero-digestive, stomach and cervical cancers. Chewing tobacco caused 7.1% of deaths from all medical causes. Conclusions: The present study is the first large study in India analysing non-smoking non-drinkers. Statistically significant excess risks were found among ever tobacco chewers for respiratory diseases combined, respiratory tuberculosis, stroke and cancer (all sites combined) compared to never tobacco chewers.

This study aimed to examine the prevalence rate of metabolic syndrome according to milk and dairy products intake and physical activity in Korean adults. After adjusting the age and sex, which are confounding factors that may affect the disease were analyzed by logistic analysis to confirm their association with metabolic syndrome. The subjects included 444 males and 807 females, aged 19 to 64 years, from the data of 'The Korean National Health and Nutrition Survey 2016-2017'. Milk and dairy product intake and physical activity were significantly associated with metabolic syndrome (OR 1.85, 95% CI 1.13 - 3.15), and low HDL-cholesterol (OR 1.52, 95% CI: 1.07 - 2.18). The results of this study show that dairy intake and physical activity tend to prevent metabolic syndrome.

Purpose: The purpose of this study was to examine differences in the prevalence of vitamin D deficiency between male and female Korean adolescents and to investigate gender-specific factors associated with vitamin D deficiency. Methods: This cross-sectional descriptive study included 975 adolescents aged 12-18 years who participated in the fifth Korean National Health and Nutrition Examination Survey (2010~2011). Multiple logistic regression using complex sample analysis was performed to examine gender-specific factors associated with vitamin D deficiency with adjustments for covariates. Results: Among the participants, 82.9% had vitamin D deficiency. The prevalence of vitamin D deficiency was higher among female adolescents (88.4%) than their male counterparts (78.4%). A rural place of residence (OR, 0.40; 95% CI, 0.19~0.87; p=.021) and daily milk intake (OR, 0.23; 95% CI, 0.07~0.75; p=.015) were significant factors significantly associated with vitamin D deficiency in males, while body mass index (OR, 8.40; 95% CI, 1.05~67.04, p=.045) and having breakfast (OR, 0.22; 95% CI, 0.10~0.49; p<.001) showed significant relationships in females. Conclusion: The results of this study provide preliminary evidence for developing effective strategies to prevent vitamin D deficiency in Korean adolescents. The different factors influencing vitamin D deficiency in males and females should be considered when providing interventions.

Reflex epilepsies are distinct but not clearly understood clinical entity. Various cerebral activities induced by simple stimulation including visual, auditory, somatosensory stimulation, as well as diverse functional tasks such as reading, calculation, complex thinking are believed to be seizure-inducing factors. We experienced two patients whose seizures were readily precipitated by complex, strenuous thinking. Both patients was teen-aged boy at the onset of seizure(13, and 15 years of age each) with normal physical and mental growth. Although first seizure was precipitated by watching TV and playing puzzles in each patient, initial diagnosis was idiopathic generalized epilepsy, possibly juvenile myoclonic epilepsy( JME). For the first few years, seizures were infrequent but mostly precipitated by the tasks needs concentration such as playing computer games, decision-making, mathematics, reading, or during the examination. EEG revealed various thinking process including reading hard books, drawing complex figure, complex calculation induced epileptic discharges even if it usually needs certain period of concentration. Phenytoin, valproic acid, clonazepam, vigabatrin, and lamotrigine sometimes abated their seizures but none of these made them seizure-free. Complex reflex epilepsy induced by thinking was proposed to be a separate type of epilepsy or a variant of JME. Age, sex, stereotypic seizure-inducing factors, clinical course, and refractory epilepsies in these patients highly suggested this type of epilepsy as a variant of JME but its refractoriness and unique provocation still needs more speculation.

Background: Non-valvular atrial fibrillation (NVAF) is associated with ischemic stroke risk in the aging population. Observational studies have indicated beneficial effects of direct-acting oral anticoagulant (DOAC) against ischemic stroke compared to warfarin. This study aimed to investigate ischemic stroke incidence and bleeding risk in patients on DOAC therapy. Methods: Using the database of Korean Health Insurance Review and Assessment-Aged Patient Sample 2015, we conducted a retrospective cohort study. Study subjects with NVAF diagnosis and prescribed anticoagulants were enrolled. Propensity score (PS) matching by age, sex, comorbidities, and medications were used. The clinical outcomes were major adverse cerebro-cardiovascular events (MACCEs, ischemic stroke/systemic embolism, myocardial infarction, cardiac death) and bleeding events. A cox proportional hazard model analysis was performed to compare the outcomes with hazard ratio (HR) and 95% confidence interval (CI). Results: Total 4,773 elderly patients with NVAF were initially included. Four PS-matched groups including rivaroxaban vs. warfarin-only (n=1,079), dabigatran vs. warfarin-only (n=721), rivaroxaban vs. dabigatran (n=721), and switchers of warfarin to rivaroxaban vs. warfarin-only (n=287) were analyzed. Every group showed statistically similar results of MACCEs and bleeding events, except for the group of rivaroxaban vs. dabigatran. Rivaroxaban users showed higher risks of bleeding events than dabigatran users (HR 2.25, 95% CI 1.01-4.99). Conclusion: In the elderly patients with NVAF, efficacy and safety outcomes among oral anticoagulants including DOACs and warfarin were similar, while rivaroxaban are more likely to have higher bleeding risks than dabigatran. Further research using large size sample is needed.

BACKGROUND/OBJECTIVES: Consumption of certain protective foods may help inhibit Helicobacter pylori (H. pylori) associated gastric pathologies. However, studies conducted to assess the efficacy of protective foods in H. pylori-infected subjects are either limited or inconsistent. This study evaluated the association of individual or a combination of protective foods on the incidence of gastric cancer (GC) in H. pylori-positive subjects through a case-control study. MATERIALS/METHODS: Subjects aged 20-79 years were selected from 2 hospitals between December 2002 and September 2006. In total, 134 patients and 212 controls tested positive for H. pylori infection. Among these, we included 82 pairs of cases and controls matched by sex, age (± 5 years), enrollment period (± 1 years), and hospital. RESULTS: A higher intake of soy products was associated with a significantly lower risk of GC than a lower intake of soy products (odds ratio [OR] = 0.37, 95% confidence interval [CI] = 0.14-0.96). Additionally, a higher fruit intake resulted in a significantly lower risk of GC than a lower fruit intake (OR = 0.35, 95% CI = 0.13-0.94). A combination of food groups was evaluated, and a lower risk of GC was observed with a high intake of both soy products and fruits (OR = 0.20, 95% CI = 0.06-0.67), high intake of soy and dairy products (OR = 0.28, 95% CI = 0.10-0.78) and high intake of fruits and dairy products (OR = 0.28, 95% CI = 0.09-0.83). CONCLUSIONS: A high intake of soy products or fruits was associated with a lower risk of GC. A combination of soy products or fruits with dairy products was associated with a lower risk of GC. A balanced intake of soy products, fruits, and dairy products may help reduce GC risk.

The purpose of this study was to analyze the association between self-reported voice problem and body mass index. Data were collected from the 5th Korea National Health and Nutritional Examination Survey (2010) from 5,811 subjects(2,503 men and 3,308 women) aged 19 years and olders. chi-square, t-test and multi-nominal logistic regression analysis were used that to compare self-reported voice problem and variable(age, sex, hight, weight, waist measurement, body mass index). body mass index(OR=1.028, 95% CI: 1.003-1.056) was independently associated with self-reported voice problem(p<0.031). also over weight-two step obesity (OR=1.765, 95% CI: 1.036-3.006) were independently associated with self-reported voice problem(p<0.036). The results of comparison verified that body mass index are valuable self-reported voice problem of risk factor. when the evaluation were conducted, what was considered body mass index is needed.

BACKGROUNDS/OBJECTOVES: Family has an impact on dietary intake of children as a proximal food environment and family structures are changing and becoming more diverse. This study was performed to identify the association between family structure and food group intake of children aged 3-18 years in Korea. SUBJECTS/METHODS: A total of 3,217 children with complete data on variables for household information, dietary intake and sampling weights were obtained from 2010-2011 Korea National Health and Nutrition Examination Survey. Children's family structure was classified into 3 groups (Living with both parents, Living with one parent and Living without parents). To evaluate children's food group intake, scores of individual food groups ('Grains', 'Meat, Fish, Eggs and Beans', 'Vegetables', 'Fruits' and 'Milk and Dairy products') was calculated from percent adherence to the recommended servings of the Korean Food Guidance System (KFGS). 'Food group mean score' was obtained by calculating the average of five food group scores. RESULTS: After adjusting for age, sex, number of family members, and household income, children living with both parents had higher scores in 'Fruits' (P < 0.01), 'Milk and Dairy products' (P < 0.05), and mean score of individual food group score (P < 0.001) compared to children living with one parent. Individual food group scores and mean scores of individual food group scores were associated with different socio-demographic factors in study children. Family structure was associated with 'Fruits,' 'Milk and Dairy products' score and mean scores of food group scores. CONCLUSIONS: These results suggested that different approach might be required to solve nutrition problem in children depending on their family structure and other socio-demographic factors.

The purpose of this study was to assess the association between habitual snoring and metabolic syndrome in the Korean population and to evaluate it's possible gender variations. The study subjects were 2,007 volunteers aged 40-69 years who participated in regular health check-ups(male:434, female:1,573) from May 2012 to December 2012. Standard interviews, anthropometrics and biochemical studies were conducted. Habitual snoring was defined as snoring more than 4 days per week. The prevalence of metabolic syndrome in our sampling pool was 17.4% (male: 20.7%, female: 16.5%), and this increased with age. After adjusting for age, smoke and alcohol consumption, sleep duration, regular exercise, the odds ratio of metabolic syndrome and it's components were increased significantly by habitual snoring. HDL-cholesterol, blood sugar, waist size were significantly higher in women, but not significantly higher in men.
