We identified 291 new cases of hypertension
among 6742 participants who remained after excluding
those with self-reported hypertension, cardiovascular disease,
diabetes, and cancer at baseline. Self-reported total
sedentary behavior was directly associated with a higher
risk of hypertension (hazard ratio, 1.48; 95% confidence
interval, 1.01 to 2.18, comparing those in the upper and
lower quartiles; P for trend .03). In subtype analyses,
interactive sedentary behavior (driving and computer use),
but not noninteractive sedentary behavior (television
viewing and sleeping), was associated with a higher risk of
hypertension.
