Association between Weight Changes over a 4-Year Period and Health-Related Quality of Life in Middle-Aged and Older Adults in Korea: The Korean Genome and Epidemiology Study Cohort.

Background: The relationship between weight change and quality of life remains controversial. This study aimed to investigate whether changes in body weight among participants in different baseline body mass index categories are associated with physical and mental health functioning.

Methods: We conducted an analysis involving 5,106 adults who participated in the Korean Genome and Epidemiology Study, a cohort comprising Korean adults aged 40 to 69 years.

Machine learning-based identification and related features of depression in patients with diabetes mellitus based on the Korea National Health and Nutrition Examination Survey: A cross-sectional study.

Patients with diabetes mellitus (DM) are twice as likely as nondiabetic individuals to develop depression, which is a prevalent but often undiagnosed psychiatric comorbidity. Patients with DM who are depressed have poor glycemic control, worse quality of life, increased risk of diabetic complications, and higher mortality rate. The present study aimed to develop machine learning (ML) models that identify depression in patients with DM, determine the best performing model by evaluating multiple ML algorithms, and investigate features related to depression.

Comparison of the Smoking Cessation of Heated Tobacco Product Users and Conventional Cigarette Smokers in Korea.

Background: Since the introduction of heated tobacco products (HTPs) in Korea in 2017, their annual sales have increased. Several studies have investigated the perceptions of HTPs and smoking cessation behaviors. For the first time, In 2019, questions focused on HTP use were introduced in the Korea National Health and Nutrition Examination Survey (KNHNES).

Understanding Social Exercise: Desire and Intention to Participate in Running Crews.

The current study investigated the determinants of the desire and intention to participate in an inner-city 'running crew' among social runners using a theoretical framework of the model of goal-directed behavior (MGB). Data were obtained from 245 social runners in Korea using an online questionnaire and primarily analyzed with the structural equation modeling technique. The results indicated that the desire to participate in a running crew was influenced most by positive anticipated emotions, followed (in descending order) by attitudes, negative anticipated emotions, social norms, perceived behavioral control, and the frequency of past behaviors.

Predicting Continued Participation in Government-Initiated Public Sports Clubs: The Role of Prior Knowledge and Awareness through Health Communications.

Physical activity is the most effective preventive medicine in enhancing our physical health and subjective wellbeing. Since 2013, the South Korean government has introduced and developed the public sports club system as a way to promote exercise and the health of the general public. The current study investigated factors underlying the general public's desires and intentions to join or participate in a public sports club (PSC) using the model of goal-directed behavior (MGB).

Correction: Effects of physical education, extracurricular sports activities, and leisure satisfaction on adolescent aggressive behavior: A latent growth modeling approach.

Predictors of Sports Gambling among College Students: The Role of the Theory of Planned Behavior and Problem Gambling Severity.

The current study investigated what influences college students' behavioral intention and behavior towards sports gambling using the theory of planned behavior (TPB) as a theoretical framework. The study also explored the moderation effect of problem gambling severity in the relationships between TPB determinants, behavioral intention, and sports gambling behavior. Data were collected from 334 college students from four different universities in the U.

Enhancing Subjective Well-Being through Physical Activity for the Elderly in Korea: A Meta-Analysis Approach.

The purpose of the current study was to meta-analytically investigate the psychological impacts of physical activity for the elderly population in Korea. The findings from 21 studies, using the comprehensive meta-analysis (CMA) program, indicated that participation in physical activity had a low, but meaningful, impact on the subjective well-being of elderly individuals. Of three exercise dose components, the duration of physical activity was the most influential, followed by the frequency and intensity of the physical activity.

Effects of physical education, extracurricular sports activities, and leisure satisfaction on adolescent aggressive behavior: A latent growth modeling approach.

The present study aimed to investigate the longitudinal influence of physical education classes, extracurricular sports activities, and leisure satisfaction on aggressive behavior among South Korean adolescents. Data were drawn from the Korea Youth Panel Survey. We used latent growth curve modeling to explain the growth trajectory of adolescent aggressive behaviors and a multi-group analysis to investigate gender differences in aggressive behavior.

Revisiting the Leadership Scale for Sport: Examining Factor Structure Through Exploratory Structural Equation Modeling.

This study examines the factor structure of the shortened version of the Leadership Scale for Sport, through a survey of 201 collegiate swimmers at National Collegiate Athletic Association Division II and III institutions, using both exploratory structural equation modeling and confirmatory factor analysis. Both exploratory structural equation modeling and confirmatory factor analysis showed that a five-factor solution fit the data adequately. The sizes of factor loadings on target factors substantially differed between the confirmatory factor analysis and exploratory structural equation modeling solutions.

Relationship Between Sport Website Quality and Consumption Intentions: Application of a Bifactor Model.

This study investigated the cognitive structure of sport website quality constructs by comparing a bifactor model (a.k.a.

Competitive Advantage in Intercollegiate Athletics: Role of Intangible Resources.

The present research explored the dynamics of competitive advantages in intercollegiate athletics by investigating the contribution of intangible resources (i.e., athletic and academic reputations) on the generation of more tangible resources (i.
