WASHINGTON DC: According to a recent study, people who spend longer than usual hours at the workplace are more susceptible to the onset of hypertension.
A considerable proportion of such individuals may also suffer a hidden form of hypertension, also known as masked hypertension, which as the name suggests may go undetected in clinical settings.
High blood pressure affects nearly half of Americans aged 18 and older and is a primary factor in more than 82,000 deaths per year. Approximately 15-30 percent of U.S. adults have a type of condition called masked hypertension, meaning their high blood pressure readings are normal during health care visits but elevated when measured elsewhere.
The new study, conducted by a Canadian research team, enlisted more than 3,500 white-collar employees at three public institutions in Quebec. These institutions generally provide insurance services to the general population.
Compared with colleagues who worked fewer than 35 hours a week, working 49 or more hours each week was linked to a 70 percent greater likelihood of having masked hypertension and a 66 percent greater likelihood of having sustained hypertension- elevated blood pressure readings in and out of a clinical setting.
The people working between 41 and 48 hours each week were linked to a 54 percent greater likelihood of having masked hypertension and a 42 percent greater likelihood of having sustained hypertension.
The findings accounted for variables such as job strain, age, sex, education level, occupation, smoking status, body mass index, and other health factors.
According to lead author Xavier Trudel, Ph.D., assistant professor in the social and preventive medicine department at Laval University in Quebec, Canada, “Both masked and sustained high blood pressure are linked to higher cardiovascular disease risk.”
“The observed associations accounted for job strain, a work stressor defined as a combination of high work demands and low decision-making authority. However, other related stressors might have an impact,” Trudel said.
The authors noted several strengths of the study, including its many volunteers, accounting for multiple factors that can impact blood pressure, repeated testing over several years, the use of wearable monitors instead of relying on workers’ reports of their blood pressure readings; and the use of the same monitors for all blood pressure measurements.
“People should be aware that long work hours might affect their heart health, and if they’re working long hours, they should ask their doctors about checking their blood pressure over time with a wearable monitor,” Trudel said.
