A new study suggests long working hours could be an independent risk factor for both masked and sustained hypertension.
The study, published in Hypertension, enlisted 3,547 white-collar employees at three public institutions in Canada. These institutions generally provide insurance services to the general population.
Overall, around 13 per cent of participants had masked hypertension, while 19 per cent of the workers had sustained hypertension.
The authors reported than when compared with colleagues who worked fewer than 35 hours a week, working 49 or more hours each week was linked to a 70 per cent greater likelihood of having masked hypertension and 66 per cent greater likelihood of having sustained hypertension. Working between 41 and 48 hours each week was also linked to a greater likelihood of having masked hypertension and a greater likelihood of having sustained hypertension.
“From a clinical perspective, assessing long working hours might be useful for the early identification of at-risk workers who could benefit from ambulatory BP monitoring,” the authors wrote.
“Increased clinical awareness on the adverse effect of long working hours could, therefore, contribute to improve hypertension prevention and management at both individual and population levels,” they added.
