Workers who clocked more than 51 hours at the office each week were 29 percent more likely to have high blood pressure than those who worked 39 hours or less, a new study from California has found.
Nearly all past research linking long work hours and high blood pressure has been done among Asian workers, Dr Haiou Yang of the University of California in Irvine and colleagues note in their report in the journal Hypertension.
To investigate whether more time on the job could drive up hypertension risk among Westerners, the researchers looked at a representative sample of 24,305 California adults who worked 11 hours or more each week.
The likelihood of having high blood pressure rose steadily with the number of hours worked, the researchers found, and persisted even after adjusting for factors such as socio-economic status and body weight.
