Consequences of worksite hypertension screening. Changes in absenteeism.
To confirm reports of increased absenteeism after worksite hypertension screening, we performed a three-stage blood pressure screening among 5888 self-selected heterogeneous workers at 11 electronics plants using standardized screening and labeling procedures. A total of 296 subjects with mean systolic blood pressure of 140 mm Hg or greater or diastolic blood pressure of 90 mm Hg or greater on all three occasions were considered to have sustained hypertension. From the untreated normotensive subjects matched for eight sociodemographic and occupational variables, we prospectively selected one to three controls for each sustained hypertensive subject. Uncorrected absenteeism rates for sustained hypertensive subjects increased 22% from baseline in the postscreening year. Correction by logarithmic transformation for skewed distributions and by rates for matched controls for temporal trends reduced these changes to statistical insignificance with high statistical power. Several subgroups exhibited trends to increased absenteeism. At 12-month follow-up, the blood pressure of the sustained hypertensive subjects showed mean decreases of 12.6/6.7 mm Hg (p less than 0.0001) after the majority had received pharmacological antihypertensive treatment. These results suggest that worksite hypertension screening and labeling produce insignificant absenteeism change overall among self-selected heterogeneous work force populations.
