Absenteeism and labelling in hypertensive subjects. Prevention of an adverse impact in those at high risk.

In this work-site population, the illness absenteeism of 259 hypertensive subjects was studied in the year after they were screened and labelled. Absenteeism due to illness increased more in 48 patients who were unaware of their hypertension (newly labelled) than in the 211 subjects who were aware. Among the newly labelled subjects, only the young subjects and those with "pure" systolic hypertension experienced increased absenteeism; the older subjects with diastolic hypertension did not. The newly labelled subjects who received active follow-up and treatment with antihypertensive medication had only minimal increases in absenteeism. In contrast, those who received active follow-up without medication, and those who received only episodic follow-up had significantly greater increases. Vigorous efforts are warranted to insure active follow-up and treatment for hypertensive subjects after their condition has been labelled. Caution should be exercised in labelling, however, if no antihypertensive treatment is initiated.
