Heart takes a pounding on overtime work

Science - Health

A study conducted by researchers from Finland, the United Kingdom, and France found a relationship between working a lot of overtime hours and the likelihood of having heart problems. The study stresses the importance of balancing work and leisure.


The title of the journal paper is 'Overtime work and incident coronary heart disease: the Whitehall II prospective cohort study.' It was published online in the European Heart Journal.

The aim of the researchers was to examine the relationship between working long hours and the incidences of coronary heart disease among middle-aged employees.

The paper is authored by Marianna Virtanen, Mika Kivimäki, and Jussi Vahtera (Finnish Institute of Occupational Health), and Jane E. Ferrie, Archana Singh-Manoux, Martin J. Shipley, and Michael G. Marmot (University College London).

The researchers studied 6,014 civil servants from the United Kingdom. In all, 4, 262 men and 1,752 women participated in the study.

The subjects ranged from 39 to 61 years of age and did not have any signs of coronary heart disease at the beginning of the study.

The study was conducted between 1991 and 1994, and then from 2002 and 2004. The average time of study for each participant was 11 years.
