Effects of labeling patients as prehypertensive.
BACKGROUND
Labeling patients as hypertensive has some negative effects. The effects of being labeled as having prehypertension are unknown. We examined whether the label of prehypertension exerts a negative effect on patients' perceived health and whether it motivates people to adopt lifestyle recommendations to prevent hypertension.


METHODS
We randomized 97 prehypertensive adults to either a labeling message or a generic (no label) message. At 3 months we assessed self-reports of change in perceived health and reported adoption of lifestyle recommendations to try to prevent hypertension.


RESULTS
Except for more participants with asthma in the label group, the 2 groups were similar at baseline. Among the 70 participants who provided 3-month follow-up data, 18 people (56%) in the no-label group and 22 people (58%) in the label group reported their health as the same; 13 people (41%) in the no label group and 16 people (42%) in the label group reported health as better; and 1 person (in no label group) reported his health as worse. At 3 months there were no differences in reports of changing eating habits (risk ratio [RR], 1.06; 95% CI, 0.86-1.31), cutting down on salt (RR, 0.99; 95% CI, 0.84-1.15), reducing alcohol intake (RR, 1.23; 95% CI, 0.80-1.90), or exercising (RR, 1.17; 95% CI, 0.91-1.51) to try to prevent hypertension.


CONCLUSIONS
Being labeled as prehypertensive seems to exert neither harmful nor helpful effects.
