Background: Several studies have revealed the frequency of family mealtimes to be inversely associated with depressive symptoms in adolescents. However, there have been few studies in older populations. This cross-sectional study investigated the association between family mealtime frequency and depressive symptoms in elderly Koreans. Methods: This study analyzed 4,959 elderly men and women (aged 65 years or older) who participated in the Korea National Health and Nutrition Examination Survey. Self-administered questionnaires were used to assess depressive status, family mealtime frequency, and covariates. Multiple logistic regression analysis was performed to evaluate the association using the eating alone group as a reference. Results: After adjusting for all covariates, participants who had family meals 3 times a day had fewer depressive symptoms than the eating alone group; adjusted odds ratios (ORs) (95% confidence intervals [CIs]) were 0.72 (0.58-0.89) for point depressiveness/anxiety and 0.73 (0.56-0.94) for depressiveness lasting for at least 2 weeks. In suicidal ideation, the OR (95% CI) of eating with family twice a day was significant after full adjusting for covariates at 0.67 (0.50-0.88). Conclusion: Family mealtimes were closely associated with depressive symptoms in elderly Koreans, which suggests that maintaining intrafamilial bonding is important for mental health in an older population.

Background: Body image is associated with the perception of people on themselves. Influencing factors are generated internally and/or externally. The most common issue pertaining to body image is body weight and weight loss. This study aimed to determine the association between body weight perception and weight loss practices among college students. Methods: A cross-sectional study was conducted involving 297 college students from private nursing colleges in the state of Kelantan, Malaysia. A self-administered questionnaire was used to assess sociodemographic characteristics, body weight perception, and weight loss methods. Weight and height were measured, and body mass index (BMI) was calculated based on weight and height measurement. The World Health Organization BMI cutoffs were applied in the study. Results: More than half (54.2%) of college students perceived their weight correctly as per actual measured BMI. A total of 51.5% of participants had tried various methods to reduce their weight. Body weight perception is associated with weight loss practices (odds ratio, 0.31; 95% confidence interval, 0.19-0.50; P<0.001) adjusted for sex, marital status, and status of having obese family members. Those who had correct body weight perception were less likely to engage in weight loss practice. Food intake restriction (42.4%) is the most popular weight reduction method among students in nursing colleges. Over a quarter of the participants chose physical exercise (25.3%) to reduce their weight, and a small number engaged in unhealthy weight loss practices. Conclusion: Body weight perception is an important factor that influences the practice to reduce weight especially among young adult group and college students.

BACKGROUND/OBJECTIVES: Taste perception is influenced by both nutritional factors and psychological factors. This study was undertaken to measure the 4 basic taste perceptions, nutrient intake, and mental health, and to examine the factors that affect insensitive taste perception in young Japanese women. SUBJECTS/METHODS: Young women in their late teens and twenties were enrolled as subjects. Taste perception was measured by applying the filter-paper disc method over areas of the chorda tympani nerve. Nutritional status was evaluated using brief, self-administered diet history questionnaires. The index of nutritional status was based on the 2015 Japanese dietary reference intakes. Mental health was assessed using the Japanese translation of the Profile of Mood States short version. This study was approved by the ethical committee at Osaka University. RESULTS: The normal taste perception group (four basic tastes [sweet, salty, sour, and bitter] identified as normal taste perception) comprised 55.4% of the subjects, while the abnormal taste perception group (more than 1 abnormal taste perception was perceived, regardless of flavor) comprised 44.6% of the subjects. There were no significant differences in nutrient intake (except manganese) and mental health between the normal and abnormal taste perception groups. Subjects who took 5 mg to less than 7.1 mg zinc per day were at significantly decreased risk of insensitive taste perception compared to subjects who consumed less than 5 mg zinc per day [Regression coefficient 0.831, 95% confidence interval 0.694-0.996]. CONCLUSION: The present results suggest that insensitive taste perception could be associated with zinc deficiency in young women in their late teens and twenties.

Background: A self-assessment questionnaire, the GERD-Questionnaire (GERD-Q) was used to determine the prevalence of GERD in adolescents, describe the related factors, and determine the impact on quality of life (QoL). Methods: The incidence of GERD was evaluated using the GERD-Q in adolescents aged 12-18 years. The Pediatric Gastroesophageal Reflux Disease Symptom Questionnaire and Quality of Life Questionnaire (PGSQ-A) for adolescents were additionally administered. Some factors considered related to GERD were also evaluated. Results: The 520 adolescents were included. The prevalence of suspected GERD, according to a GERD-Q cutoff score of ${\geq}7$ was 32.9%, and those drinking soda were 1.7 times more likely to have GERD (95% confidence interval, 1.3-2.2; p<0.001). However, soda consumption was not a risk factor for development of GERD symptoms. Applying a cutoff score of ${\geq}8$, only 10.9% of the participants had a positive GERD score, but the association with soda consumption persisted. The median PGSQ-A score in subjects suspected of GERD was 8 (range 0-37) on weekends and 1 (range 0-17) during weekdays (p<0.001) compared to those not suspected of GERD, with a median of 2 (range 0-27) during weekends and 0 (range 0-10) during weekdays. Heartburn, regurgitation, and extraesophageal symptoms correlated significantly with QoL (p<0.001). Conclusion: The prevalence of suspected GERD in adolescents was 32.9% or 10.9%, depending on the cutoff score used. There was a statistically significant difference in PGSQ-A scores between the subjects suspected or not of GERD, indicating an impaired QoL.

복합민족국가 미국의 신속한 국가정체성 확립을 위한 주요 시발점이 되었던 대통령기록관은 미국이라는 한 자본주의 국가가 자신의 대통령을 기념하는 방법이다. 이것은 분명 미국이기에 가능했고, 또한 미국이기에 이해되는 것들이기도 했다. 미국이 대통령기록관시스템을 통해 그 어떤 행정기록보다 풍부한 자원을 확보하고 이용 가능하게 한 것은 엄연한 사실이다. 그러나 기록보다는 박물 전시에 치중하며, 이를 통해 국가적 애국심을 고착시키며 야기 시켰던 역기능들은 여전히 간과할 수 없는 요소들로 자리하고 있다. 이집트에 고대 파라오를 위한 피라미드가 있다면, 미국에는 전직 대통령을 위한 성전인 대통령기록관이 있다는 역사가들의 비유는 미국 대통령기록관이 자의적 역사해석을 통해서 퇴임 대통령을 긍정적으로 그리기 위해 얼마나 극도로 노력해왔는지를 보여준다. 그 영웅화가 가능하게 된 배경에는 미국식 소유관념과 미국식 낙관주의 문화가 있었음을 배제할 수 없다. 미국대통령기록관이 비록 그들의 방식으로 제도화하고 발전되었지만 거기에는 우리가 기꺼이 배울 점도 있고, 도저히 따라가서는 안 되는 점도 공존한다. 여기서 중요한 것은 균형 잡힌 시각으로 외국 사례를 수용하고 제대로 직시하는 시야를 갖는 것이다.

Background: The extent of coverage rate of the public health insurance is still insufficient to meet healthcare needs. Private health insurance (PHI) plays a role to supplement coverage level of national health insurance in Korea. It is expected that reduce unmet need healthcare. This study was aimed to identify relationship between PHI type and the unmet healthcare need and its associated factors. Methods: Data were obtained from the 2014 Korea Health Panel Survey using nationally representative sample was analyzed. Respondents were 8,667 who were adults over 20 years covered by PHI but have not changed their contract. According to the enrollment form, PHI was classified into three types: fixed-benefit, indemnity, and mixed-type. To identify factors associated with unmet needs, multiple logistic regression conducted using the Andersen model factors, which are predisposing factors, enabling factors, and need factors. Results: Our analysis found that subjects who had PHI with mixed-type were less likely to experience unmet health care needs compared than those who did not have it (odds ratio, 0.80; 95% confidence interval, 0.66-0.98). As a result of analyzing what affected their unmet healthcare needs, the significant factors associated with unmet medical need were gender, marital status, residence in a metropolitan area, low household income, economic activity participation, self-employed insured, physically disabled, low subjective health status, and health-risk factors such as current smoking and drinking. Conclusion: The results of this study suggest that having PHI may reduce experience of unmet healthcare needs. Findings unmet healthcare needs factors according to various subjects may be useful in consideration of setting policies for improving accessibility to healthcare in Korea.

Objectives: The purpose of this study was to assess the association between the use of humidifier disinfectant (HD) and bronchiolitis and allergic rhinitis diagnoses in Korean children. Methods: This study used data from the $8^{th}$ panel study on Korean children in 2015. Of these 2150 cases, 1598 cases were used for the final study. Diagnoses of bronchiolitis and allergic rhinitis by medical doctors were self-reported as outcome variables. Whether children had used HDs or not, the periods of using HDs were used as independent variables. Results: A total of 77.0% had used a humidifier, and the rate of HD usage among humidifier users was found to be 35.4%. When comparing 'children who had used HDs for less than 12 months' and 'children who had used HDs for more than 12 months' with 'children who had not used HDs', the adjusted odds ratio (OR)s for 'bronchiolitis' were 1.38 (95% confidence interval (CI), 1.36-1.40) and 1.80 (95% CI, 1.71-1.89), respectively. When comparing 'children who had used HDs for less than 12 months' and 'children who had used HDs for more than 12 months' with 'children who had not used HDs', the adjusted ORs for 'allergic rhinitis' were 1.44 (95% CI, 1.42-1.46) and 1.43 (95% CI, 1.37-1.49), respectively. Conclusions: The period of using HDs was statistically significantly associated with increased odds of bronchiolitis and allergic rhinitis. The results of this study will provide a very useful scientific basis for establishing the environmental health policy and using the educational data related to the use of humidifier disinfectant in the future.
