Abstract
Although family-related demands play a role in the effect of psychosocial work characteristics on health, research on work-related health has neglected the family domain. The aim of the present study was to identify the effects of family demands and work–life conflict (WLC) on musculoskeletal disorders (MSDs) among Korean workers. We analyzed data from the nationally representative Korean Working Conditions Survey conducted with 50,007 workers in 2014. Logistic regression analyses stratified by gender were performed to identify gender differences, and interaction terms including WLCs and key covariates were also incorporated. Childcare demands (odds ratio (OR), 1.16) were related to MSD only in male workers, whereas homemaking (OR, 1.09) and eldercare (OR, 1.26) demands were related to MSDs only in female workers. WLC was also associated with MSDs among both male (OR, 1.50) and female (OR, 1.55) workers. We found no gender difference in the effect of WLC on MSDs (p = 0.91). Moreover, childcare demands may exacerbate the effect of WLC on MSDs. Our data suggest that family demands and WLC could be important targets of workplace interventions to prevent MSDs, and future research should evaluate the role of family demands and WLC as stressors in the workplace.
Highlights
Musculoskeletal disorders (MSDs) are among the most common and costly health problems affecting working populations and constitute a major cause of disability [1]

This study investigated whether family demands and WLC are related to MSDs among Korean workers by investigating three research questions
Summary
Musculoskeletal disorders (MSDs) are among the most common and costly health problems affecting working populations and constitute a major cause of disability [1]. The prevalence and burden from MSDs are exceptionally high [2]. It has been estimated that approximately 25–30% of European employees experience MSDs [3]. 54.5% of adults in the United States, which amounts to 125 million people, have suffered from one or more MSD [4]. In the United States, the annual average direct cost of MSDs was estimated to be $576 billion, or 4.5% of GDP [6]. MSDs accounted for 21.3% of the years lived with disability (YLDs), behind only mental and behavioral problems (23.2%) [7]
