Background: The prevalence of multiple job-holding (MJH) is expected to show an upward trend among Korean workers, yet its potential impact on workers' health remains poorly discussed. This study aimed to explore the association between MJH and experience of physical and psychological symptoms in various aspects among active Korean workers and to identify its differences depending on workers' gender.
Methods: We conducted a population-based cross-sectional study among South Korean workers aged 15-59 using data from the 6th Korean Working Conditions Survey. The final study sample comprised 34,175 participants. MJH status and symptoms, such as musculoskeletal pain, headache or eyestrain, fatigue, insomnia, and anxiety, were measured by self-reported data. Logistic regression analyses were performed on the total sample and gender-stratified groups, with adjustments for the sociodemographic and occupational characteristics of the participants.
Results: One hundred thirty-five men and 103 women were defined as multiple job-holders (MJHers) among the study sample. When adjusted for sociodemographic and occupational characteristics, MJHers suffered more events of headache or eyestrain (odds ratio [OR]: 1.85, 95% confidence interval [CI]: 1.23-2.78) and anxiety (OR: 1.99, 95% CI: 1.05-3.79). Gender-stratified analyses with adjustment showed that among women workers, MJH was associated with musculoskeletal pain (OR: 1.85, 95% CI: 1.02-3.34), headache or eyestrain (OR: 2.53, 95% CI: 1.37-4.67), fatigue (OR: 2.38, 95% CI: 1.29-4.40), insomnia (OR: 1.92, 95% CI: 1.04-3.57), and anxiety (OR: 2.83, 95% CI: 1.11-7.20).
Conclusions: We found a significant association between MJH and various symptoms. Women MJHers were revealed to be a more vulnerable population than their men counterparts. Further research should account for the social context of MJH, and appropriate monitoring and intervention for maintaining the well-being of MJHers are needed.

Investigating the influence of working status changes on physical activity and non-communicable diseases in Korean middle-aged and older adults: insights from a longitudinal panel study.

Background: Non-communicable diseases (NCDs) are a major global health challenge and occupational status is a critical determinant influencing NCD development, yet many cross-sectional studies have only linked current occupational status with specific diseases, overlooking broader temporal factors. The primary aim of the present study was to comprehensively elucidate the intricate interplay between alterations in working status, NCDs, and physical activity (PA) among Korean middle-aged and older adults, employing a longitudinal panel study design.
Methods: This study utilized longitudinal data from the Korean Longitudinal Study of Aging, covering the period from 2006 to 2020, with a median follow-up duration of 10 years.
The impact of transient air pollution exposure on worker performance in Chinese soccer players.

Using a unique dataset on the performance of soccer players in China (retrieved from 632 matches involving 24 teams during the 2014 to 2016 seasons), we investigate the effect of air pollution on different performance indicators that rely on different mixtures of the physical and cognitive inputs of players. To ensure a causal interpretation, we implement an instrumental variable (IV) approach using thermal inversion as the instrument for air pollution. We found that players' performance indicators, especially those more related to cognitive factors, are more strongly influenced by air pollution.

This population-based cohort study aimed to evaluate the risk of osteoporosis and fractures associated with higher-potency statin use compared to lower-potency statin use in patients with stroke, using data from the Health Insurance and Review Assessment database of South Korea (2010-2019). Patients who received statin within 30 days after hospitalization for a new-onset stroke (n = 276,911) were divided into higher-potency (n = 212,215, 76.6%) or lower-potency (n = 64,696, 23.
