Association between sleep duration and dyslipidemia in premenopausal and postmenopausal women
Cardiovascular disease (CVD) is one of the leading causes of death worldwide, and dyslipidemia—a major risk factor for CVD—varies by sex, age, and menopausal status. While some studies have explored the relationship between sleep duration and dyslipidemia, findings remain inconsistent, and most have not accounted for menopausal status. This study investigates the association between sleep duration and dyslipidemia in premenopausal and postmenopau…

Implication of findings from a two-wave survey on embitterment in South Korea for strategies to promote mental health of the general public
Our study highlights embitterment as a dynamic emotion that can either be aggravated or moderated over time. Embitterment can be elicited by joint effects of multiple social and interactional factors including known embitterment correlates, and relative deprivation is confirmed as a possible core elicitor of embitterment in the context of comparative justice. These findings imply that additional longitudinal research and development of practices …
Reasons for Initiation and Regular Use of Heated Tobacco Products among Current and Former Smokers in South Korea
South Korea is the world’s second-largest heated tobacco product (HTP) market after Japan. HTP sales in South Korea have increased rapidly since May 2017, accounting for 10.6% of the total tobacco market in 2020. Despite this, little is known as to why HTP consumers who were current and former smokers started using HTPs and used them regularly. We analyzed cross-sectional data for 1815 adults (aged 19+) who participated in the 2020 International …
Association between depression, anemia and physical activity using isotemporal substitution analysis
Moderate to vigorous physical activity had a protective association against depression in both anemic and non-anemic groups. Anemic patients are recommended to perform physical activity for any duration acceptable to them to prevent depression
Working hours, social engagement, and depressive symptoms
Maintaining an optimal number of working hours and degree of social engagement are necessary to minimize the risk of depressive symptoms in older adults. Based on these findings, we suggest that fulfillment for work and life and their balance are important for older adults and propose work-life fulfillment balance
