Sleep duration, perceived job stress and risk of hypertension among engineering workers

Introduction: PT. Y is a company engaged in providing Engineering, Procurement and Construction services for development and maintenance for Oil and Gas Company, which spending most of their valuable time at work. Therefore the workers have a short sleep duration and can affects their quality of health. There have been seven cases of hypertension in PT Y over the past six years (2012-2018). This study aims at examining blood pressure a hypertension risks related to sleep duration and job stress perceived of engineering workers. Methods: A quantitative research using the observational analytic method. The samples were 104 workers engineering workers of PT Y. The research sample is based on sample calculation using the simple random sampling method. Results: Workers with abnormal sleep duration (<6 hours, or> 8 hours) had higher average systolic blood pressure (128.43 ± 7.17) compared to workers having normal sleep duration, (121.51 ± 10.77) with P value < 0.001. The variable of job stress variable showing that respondents who have the perception of experiencing work stress have an average TDS of 127.32 ± 7.84 and a higher TDD of 85.65 ± 6.29 with P value <0.001. For physical activity, there were 70.5% workers who not fit the recommendation had the risk of hypertension but the correlation not statistically significant (p>0.05). Conclusion: There found significant correlation between abnormal sleep duration and job strain which lead to hypertension, and significant differences of systolic and diastolic blood pressure rate.
