This study investigated gender differences in the relationship between long working hours and metabolic syndrome. Data based on the Sixth National Health and Nutrition Examination Survey (2014) pertaining to a total of 1,145 paid workers were analyzed. Working hours were divided into three groups (40-51 hours/week, 52-59 hours/week, ≥ 60 hours/week). The relationship between working hours and metabolic syndrome was then analyzed after adjusting for general and occupational characteristics, using a multiple logistic regression model. Working 40-51 hours per week was associated with the lowest metabolic syndrome among female workers (11.2%), whereas it was associated with the highest metabolic syndrome among male workers (28.0%). After adjusting for general and occupational characteristics, female workers working≥60 hours per week showed odds ratios of 2.21 [95% confidence interval (1.07, 4.57)], compared to those who worked 40-51 hours per week. However, no clear association between long working hours and metabolic syndrome was found among male workers. The results suggest that working long hours, especially≥60 hours per week, is related to metabolic syndrome among female Korean workers.

Metabolic syndrome is an important cluster of coronary heart disease risk factors. However, it remains unclear to what extent metabolic syndrome is associated with demographic and potentially modifiable lifestyle factors among Korean persons with physical disabilities. This study aimed to determine the prevalence and influencing factors of metabolic syndrome among persons with physical disabilities using the Korean National Health Insurance Service-National Sample Cohort. The Adult Treatment Panel III criteria were used to define metabolic syndrome influencing factors and prevalence, which were evaluated in a representative sample from the 2013 Korean National Health Insurance Service-National Sample Cohort database. Characteristics were compared based on frequency using the χ2 test. The associations between metabolic syndrome and its risk factors were estimated using logistic multivariable regression analysis. Metabolic syndrome was detected in 31.5% of the surveyed persons with physical disabilities. Female sex, age of ≥65 years, smoking, greater alcohol consumption, physical inactivity, higher body mass index, and a family history of diabetes were associated with increased risks of metabolic syndrome. The major risk factors for metabolic syndrome among persons with physical disabilities were obesity and older age. Performing physical activity was associated with a lower risk of metabolic syndrome. Therefore, we recommend using a continuous obesity management program and physical activity to prevent metabolic syndrome among persons with physical disabilities.

The internet provides convenient access to information about non-suicidal self-injury (NSSI) owing to its accessibility and anonymity. This study aimed to explore the distribution of topics regarding NSSI posted on the internet and yearly trends in the derived topics using text mining. We searched for the keyword “non-suicidal self-injury” (Ja-Hae in Korean) in the Naver Q&A using the statistical package R. We analyzed 7893 NSSI-related questions posted between 2009 and 2018. Text mining was performed using latent Dirichlet allocation (LDA) on the dataset to determine associations between phrases and thus identify common themes in posts about NSSI. In the LDA, we selected the following 10 most common topics: anger, family troubles, collecting information on NSSI, stress, concerns regarding NSSI scarring, ways to help a non-suicidal self-injurious friend, depression, medical advice, ways to perform or stop NSSI, and prejudices and thoughts regarding non-suicidal self-injurious people. This study provides valuable information on the nature of NSSI questions posted online. In future research, developing websites that provide NSSI information and support or guidance on effectively communicating with NSSI is necessary.
