Masked hypertension: different blood pressure measurement methodology and risk factors in a working population.

Objectives: To estimate the prevalence of masked hypertension when the same ambulatory device is used for both manual and ambulatory blood pressure measurements and to measure associations with lifestyle risk factors in a working population.

Methods: White-collar workers were recruited from three public organizations. Blood pressure was measured at the workplace using Spacelabs 90207 for manual measurements (mean of the first three readings taken by a trained assistant) followed by ambulatory measurements (mean of every other reading obtained during the working day).

[Validity of occupational stress and decision latitude on health in the National Population Health Survey of 1994-95].

Psychosocial environment at work is now considered a health determinant. The National Population Health Survey (NPHS) of 1994-95 is the first study in which psychological demands and decision latitude at work were measured in a random sample of the Canadian population. However, psychometric properties of the scales used in NPHS to measure these factors are not known.

[Impact of occupational stress on health status in Canada].

Studies have shown that high psychological demands and low decision latitude may be involved in the development of major health problems. The objective of the current study was to describe the importance of these factors among the Canadian working population. The sample included 7,250 participants from the National Population Health Survey (NPHS) of 1994-95.

Prospective evaluation of cardiac risk indices for patients undergoing noncardiac surgery.

Background: Prediction of perioperative cardiac complications is important in the medical management of patients undergoing noncardiac surgery. Several indices have been developed to aid prediction, but their performance has not been systematically compared.

Objective: To compare four existing methods for predicting perioperative cardiac risk.

Psychosocial factors at work, smoking, sedentary behavior, and body mass index: a prevalence study among 6995 white collar workers.

This cross-sectional study examined whether psychosocial factors at work were associated with smoking, sedentary behavior, and body mass index. The study population was composed of 3531 men and 3464 women employed as white collar workers in 21 organizations. Data were collected at worksites.
