Happiness and health behaviors in South Korean adolescents: a cross-sectional study / 한국역학회지

OBJECTIVES: We examined the associations between happiness and a wide range of health behaviors in South Korean adolescents. METHODS: Study data were derived from the ninth Korea Youth Risk Behavior Web-based Survey administered from June to July 2013. In addition to happiness levels, the questionnaire included items on sociodemographics and health-related lifestyle factors (smoking, drinking, eating breakfast, fruit and vegetable consumption, physical activity, sedentary behavior, and hours of sleep). RESULTS: The multivariate analysis revealed that higher levels of happiness were associated with not smoking or drinking, eating breakfast, eating fruits daily, vegetable consumption, participating in at least 60 minutes of physical activity a day, avoiding sedentary behavior, and hours of sleep. Additionally, sex differences were found in relationships between happiness and eating fruit daily, participation in physical activity, and sedentary behavior. CONCLUSIONS: These results encourage public health professionals to consider the psychological aspects of adolescent life in working to improve their health behaviors and outcomes.

What predicts the trust of online health information? / 한국역학회지

OBJECTIVES: Little attention has been paid to levels of trust in online sources of health information. The objective of this study was to investigate levels of trust in various sources of health information (interpersonal channels, traditional media, and Internet media), and to examine the predictors of trust in health information available on the Internet. METHODS: A questionnaire was administered to 1,300 people (20 years of age or older), evaluating levels of trust in various sources of health information. RESULTS: The highest level of trust was expressed regarding interpersonal channels, with hospital physicians regarded as the most trusted source of information age and income showed an association with trust in online information sources. Elderly people were not likely to trust Internet news sources, and high incomes were found to be strongly associated with trust in online sources of information overall. CONCLUSIONS: Public health organizations must consider the predictors for trust in various sources of information in order to employ appropriate media when targeting vulnerable individuals or developing messaging strategies for health professionals.

Autoimmune hemolytic anemia during PEG-interferon and ribavirin treatment for hepatitis C / 대한내과학회지

The current best treatment for HCV infection is combination therapy with PEG-interferon and ribavirin. This combination therapy has markedly increased the number of sustained virologic responders but is associated with various side effects, especially hematological abnormalities. We recently experienced a 45-year-old man who developed PEG-interferon induced autoimmune hemolytic anemia (AIHA) and retinal premacular hemorrhage. The worsening hemolysis after ribavirin withdrawal and exclusion of other causes implicated PEG-interferon as the cause of the AIHA. To the best of our knowledge, this is the first case reported from Korea. Treatment with PEG-interferon requires careful follow-up, as it can induce or exacerbate autoimmune diseases.
