Life events, mood, mental strain and cardiovascular risk factors in Swedish middle-aged men. Data from the Swedish part of the Renault/Volvo Coeur Study

The associations between life events, mood, mental strain and cardiovascular risk factors were investigated in the Renault/Volvo Coeur Study. About 1,000 men, blue-collar and white-collar workers, were asked by means of interview-administered questionnaires about life events experienced during the year preceding the screening, about mood and mental strain and about smoking, alcohol consumption and exercise habits. Blood pressure, concentration of serum lipids and blood glucose, and anthropometric measures were determined in a screening procedure. Negative life events, especially work-related, were associated with depressed mood and mental strain but not with elevation of biological risk factors such as elevated blood pressure and serum lipids. Depressed mood and mental strain were related to increased tobacco consumption in blue-collar workers and increased alcohol consumption in white-collar workers.
