Nonverbal communication (NVC) is important in the patient-physician relationship, but the effect of NVC education is not well kown. In this study, we try to identify if students' NVC abilities are improved through communication training. First-year medical students conducted medical interviews, which were performed with standardized patients (SPs) before and after communication skill education, and recorded in video. Fifty-one students were enrolled for this study. Two researchers used the NVC checklist, which consists of 12 nonverbal behaviors, to analyze and compare the students' nonverbal expressions in the interviews recorded before and after the education. After the students participated in communication training, open body position and adequate facial expression were increased while unnecessary silence, un-purposive movements, and giggling were decreased. These results can be interpreted as positive effects of the education. However, hand gesture was increased as a negative effect of the education. The total NVC score of the 12 nonverbal behaviors in the NVC checklist improved significantly, rising from 8.56 to 10.03. Communication skill education using SPs can improve nonverbal behaviors of medical students, especially facial expression, un-purposive movement, body position, unnecessary silence, and giggle, but not hand gesture. Further research is needed on a variety of teaching methods to improve NVCs.

Background: Cancer survivors experience decreased physical function and reduced muscle strength, which leads to lower quality of life (QOL). The hand grip strength (HGS) can be a predictor of poor health-related QOL as a parameter of sarcopenia The purpose of this study was to investigate the relationship between low FIGS and QOL in cancer survivors and healthy controls. Methods: We analyzed 392 cancer survivors and 1,176 healthy controls from the Korea National Health and Nutrition Examination Survey, 2014-2017. We defined low HGS as 2 standard deviation values for healthy young Korean adults from a previous study. QOL was evaluated using the European Quality of Life Scale-Five Dimensions. A complex sample logistic regression model was used to assess the relationship between each dimension of low HGS and QOL. Results: The odds ratios (ORs) for decreased QOL were significantly higher in male cancer survivors with low HGS on self-care (OR, 8.51; 95% confidence interval [CI], 1.69-42.83) and usual activities (OR, 6.63; 95% Cl, 1.22-36.03). The ORs for problems in mobility (OR, 5.87; 95% CI, 2.04-16.91), usual activities (OR, 14.46; 95% CI, 3.84-54.44), pain/discomfort (OR, 4.90; 95% CI, 2.00-12.01), and anxiety/depression (OR, 6.43; 95% CI, 2.16-19.12) were significantly high in female cancer survivors with low HGS. However, healthy controls showed no significant relationship between low HGS and QOL. Conclusion: For cancer survivors, low HGS was associated with poor QOL in some domains. Strategies to increase muscle strength must be considered to improve the QOL of cancer survivors.

Nonverbal communication (NVC) may be a crucial factor affecting effective communication between patients and medical students during the objective structured clinical examination (OSCE), but it has not been intensively studied. We examined NVC and its correlation with patient-physician interaction (PPI) in the OSCE. A total of 68 video recordings of routine check-up OSCEs were included. A checklist for NVC was developed that included seven nonverbal factors in a mute state (NVM) and four nonverbal factors in speech (NVS), and one point was assigned to each factor. The scores for history taking, PPI, NVM, and NVS were compared, and correlations of each score were evaluated. Students with adequate facial expressions, accorded speech rate and voice volume, adequately matched voice tone, and few or no moments of unnecessary silence showed better PPI scores. The PPI score was correlated with history taking and the NVS score, but not the NVM score. Our results suggest that NVS may be more influential to PPI during OSCEs than NVM. Communication teachers should help students to be better prepared to use both NVS and NVM properly.

Inadequate nutritional intake is common, especially among elderly individuals. Although micronutrient intake may help fill nutritional gaps, the effects of multi-vitamin and mineral supplements (MVMS) among the Korean elderly are not well known. Therefore, we investigated the nutrition-improving effects of a single MVMS. A total of 2478 people aged ≥65 years who participated in the Korea National Health and Nutrition Survey 2018–2020 were analyzed. Nutrient intake from food and supplements was measured using the 24 h recall method. We compared the nutritional intake and insufficiency between the food-only group (n = 2170) and the food and MVMS group (n = 308). We also evaluated the differences in inadequate nutritional intake after taking MVMS with food. The analysis included vitamins A and C, thiamine, riboflavin, niacin, calcium, iron, and phosphorus. The proportion of insufficient intake ranged from 6.2% to 80.5% for men and from 21.2% to 82.4% for women, depending on the nutrients. Intake of MVMS with food was associated with lower rates of inadequacy (3.8–68.5% for men and 3.3–75.5% for women) compared to the food-only group. The results suggest that micronutrient deficiency frequently occurs in the Korean elderly population and can be improved by MVMS intake.

Dry eye syndrome is a common health problem in the adult population. Many risk factors including age, sex, prior eye surgery, various chronic diseases, and lifestyle factors can affect its development. We have evaluated the risk of dry eye syndrome based on the frequency of coffee consumption among Korean adult population. A total of 9,752 adults with age 19 years and older were randomly selected between 2010 and 2012. They have all participated in the National Health and Nutrition Examination Survey V of Korea. Dry eye syndrome was being diagnosed by the physicians at some points in the participant's lifetime. The average daily coffee intake was divided into the following: less than 1 cup, 1 to 2 cups, and 3 cups or more. Various physio-environmental factors and medical conditions were used as correction variables to assess the risk of dry eye syndrome in relation to the frequency of coffee consumption. The prevalence of dry eye syndrome decreased to 9.2%, 8.8%, and 6.3% as coffee consumption increased from less than 1 cup to 1-2 cups and more than 3 cups, respectively. However, there was no significant relationship between the frequency of coffee consumption and the risk of dry eye syndrome after adjusting various risk factors. There is no relationship between the frequency of coffee consumption and risk of dry eye syndrome.
