The relationship between working hours and the intention to quit smoking in male office workers: data from the 7th Korean National Health and Nutrition Examination Survey (2016–2017): Eui Hyek Choi, Dae Hwan Kim, Ji Young Ryu; Ann Occup Environ Med 2021;33:e13. Published online May 4, 2021; DOI: https://doi.org/10.35371/aoem.2021.33.e13

Background

The intention to quit smoking is one of the most important factors in smoking cessation. Long working hours is also a constant issue, and many studies have shown an association between the working hours and diseases, including cardiovascular and gastrointestinal diseases. This study evaluated the relationship between working hours and the intention to quit smoking among Korean male office workers, and blue collar workers for comparison.

Methods

This study was based on the Seventh Korea National Health and Nutrition Examination Survey (2016–2017). A total of 1,389 male workers were smokers, and then office workers and blue collar workers were selected. Logistic regression was used to calculate the odds ratio (OR) for the intention to quit smoking according to smoking-related characteristics and working hours after adjusting for age group, body mass index (kg/m²), marital status, household income (quartile), educational level, drinking, exercise, smoking-related characteristics (smoking initiation age, smoking amount, and attempt to quit smoking more than 1day in the past year) and working hours.

Results

The percentage of workers who had the intention to quit smoking in 6 months was higher in office workers (38.9% for office workers and 29.4% for blue collars, p = 0.017). Blue collar workers had higher percentages of workers who worked more than 52 hours per week (19.8% for office workers and 38.9% for blue collar workers, p < 0.001). Logistic regression analysis showed that working > 52 hours per week was significantly associated with a lower intention to quit smoking within 6 months among male office workers (OR = 0.30, 95% confidence interval = 0.14–0.66).

Conclusions

Working more than 52 hours per week was positively related with a lower intention to quit smoking among currently smoking male office workers. Further studies are needed considering more work-related variables such as job stress and physical load.

Background

Previous studies have classified cameramen’s job as physiologically heavy work and identified the risk factors of work-related musculoskeletal disorders (WRMDs) in cameramen. However, those studies limited their research subjects to cameramen. In this study, we compared the frequency and severity of WRMDs between cameramen and office workers.

Methods

A total of 293 subjects working in four broadcasting companies in Korea were recruited. A questionnaire survey was conducted for a month, starting in October 2016. The subjects were divided into cameramen and office workers according to their occupation. We compared the frequency and severity of WRMDs and ergonomic risk assessment results between the two groups.

Results

The high-risk WRMD group had a higher proportion of cameramen than office workers. Moreover, the high ergonomic risk group also had a higher proportion of cameramen than office workers for WRMDs in the upper extremities and waist+lower extremities. In the multivariable-adjusted model comparing cameramen and office workers, the odds ratio (OR) with 95% confidence interval (95% CI) for high-risk WRMDs was 3.50 (95% CI: 1.92–7.72) for the upper extremities and 3.18 (95% CI: 1.62–6.21) for the waist and the lower extremities. The ORs by body parts were 3.11 (95% CI: 1.28–7.57) for the neck, 3.90 (95% CI: 1.79–8.47) for the shoulders, and 4.23 (95% CI: 1.04–17.18) for the legs and feet.

Conclusions

Our study suggests that cameramen are at high risk of WRMDs. Workplace improvements and management of the neck, shoulders, and lower extremities, which are susceptible to WRMDs, are necessary to prevent musculoskeletal disorders among cameramen.

Objectives

Vitamin D deficiency is increasing worldwide. However, few studies have attempted to examine the vitamin D status of wage workers and the correlation between vitamin D deficiency and working conditions. Hence, we aimed to evaluate the prevalence of vitamin D deficiency and the association between occupational conditions and vitamin D deficiency among Korean wage workers.

Methods

Wage workers aged 20–65 years from the 5th Korea National Health and Nutrition Examination Survey (KNHANES 2010–2012; n = 5409) were included in our analysis. We measured the prevalence of vitamin D deficiency and identified the correlations with the working conditions of these subjects.

Results

The prevalence of vitamin D deficiency in male and female subjects was 69.5% and 83.1%, respectively. Among the male subjects, a significant correlation between vitamin D deficiency and working conditions was observed among shift workers, office workers, and permanent workers. No significant correlation with any type of working conditions was observed among female subjects.

Conclusion

The prevalence of vitamin D deficiency among Korean wage workers was very high and was found to correlate significantly with working conditions, likely because of insufficient exposure to sunlight associated with certain types of work. Wage workers require more frequent outdoor activity and nutrition management to maintain sufficient vitamin D level.

Cumulative Trauma Disorders Among Shipyard Workers and Application of Baseline Checklist for Risk Assessment: Sang Hwan Han, Nam Jong Paik, Donghyun Park, Ki Eon Jang, Myung Hag Lee, Jong Tae Park, Dae Sung Kim, Yeon Sook Lee, Kyung Ja Paik, Young Soo Shin, Dong Bin Song; Korean Journal of Occupational and Environmental Medicine 1997;9(4):579-588. Published online December 31, 1997; DOI: https://doi.org/10.35371/kjoem.1997.9.4.579

Abstract PDF

Cumulative trauma disorders were surveyed in a cross-sectional study of 100 male ship yard workers and 43 male office workers. And baseline checklist for risk assessment of cumulative trauma disorders was applicated in a ship making process. Cases of cumulative trauma disorders were defined using physical examinations and electronic diagnostic methods. Data on demographics, individual factors (medical condition), work organization and psychosocial aspects of work were obtained by questionnaire. Association between the above factors and cumulative trauma disorders were assessed by multiple logistic regression models. 29(29 %) participants of male shipyard workers and 4(9.2 %) study subjects of male office workers met our case definitions for cumulative trauma disorders. The myofascial pain syndrome of neck muscles(12 % of participants) and carpal tunnel syndrome(5 % of participants) were the major two medical conditions in shipyard workers. The odds of male shipyard workers for cumulative trauma disorders to male office workers was 3.15 after adjustment of age(95 % C.I. :2.25-5.44). And the variables such as duration of present job, HIVD condition, and surges in workload were associated at least one of the cumulative trauma disorders in the final models (p<0.05) . This study indicates that work related upper extremity musculoskeletal disorders are relatively common among shipyard workers, and shows that the psychosocial factors is not likely to be related to the occur rences of these disorders in heavy workers. Also we developed baseline checklist for risk assessment of cumulative trauma disorders. The checklist was unique in that its expected users were industrial hygienists and occupational healthing nurses who did not have much ergonomic background and in that it was targeted to Korean workers in various types. As the first application of the checklist, shipyard workers were evaluated.

Sick Building Syndrome in Office Workers: Daehee Kang; Korean Journal of Occupational and Environmental Medicine 1996;8(3):519-525. Published online December 31, 1996; DOI: https://doi.org/10.35371/kjoem.1996.8.3.519

Abstract PDF: A cross-sectional study was conducted to evaluate the relationship between sick building syndrome (SBS) and the factors affecting SBS among 90 office workers. The study consisted of 1) a review of previous environmental investigations, 2) measurements of COy temperature, and relative humidity (RH), 3) a questionnaire survey of symptom prevalence and perception of environmental conditions using the National Institute for Occupational Safety and Health Indoor Air Quality (NIOSH IAQ) questionnaire, and 4) confidential interview and a review of medical records of employees having respiratory symptoms. COy temperature, and RH measured on the day of questionnaire survey were within the recommended range by American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). Sixty-six percent of respondents were women and 60% considered their job description either "managerial (28%) "or "professional (32%)". Respondents had worked in the building for an average of 5.8 years. Forty-four percent reported having SBS defined as "having one or more symptoms that had occurred at work one or more days a week and tended to get better when away from work". Sex(p=0.001), duration of computer use(p=0.02), use of laser printer (p=0.02), use of cleanser or other office chemicals (p=0.004), feeling too little air movement (p=0.001), feeling air too dry(p=0.001), and unsatisfied with the current job(p=0.02) were related to an increased prevalence of SBS. Use of cleanser or other office chemicals (pO. 01), feeling too little air movement (p=0.01), and feeling air too dry (p=0.02) remained significant predictors of SBS when adjusting other variables by logistic regression analysis. The results of medical record review revealed a discrepancy in the number of diagnosed asthma cases by personal physician and an independent physician. Although this study contains several .limitations (e. g., cross-sectional study, small numbers of study, subjects, etc.), these results indicated that SBS is related to personal, environmental, and psychosocial factors and the precision of diagnosis is critical when evaluating environment-relatedness during disease cluster investigation.
