Alcohol consumption and blood pressure in recently hospitalised patients.
One-thousand-four-hundred-and-fifty-three patients admitted to a teaching hospital, haemodynamically stable and not severely ill nor in significant pain, were interviewed within 48 h of admission and demographic data and a detailed drinking history were obtained. Supine blood pressures (BP) were recorded on the day following admission. The mean age of the population was 60.5 +/- 19.9 years (range 16-99 years) and the mean reported alcohol consumption was 67.8 +/- 273 g/week (range 0-6125 g/ week). Thirty-six percent of patients were currently receiving antihypertensive drug therapy. On multivariant analysis, reported alcohol intake was not significantly related to systolic BP (beta = 0.000, p = 0.902) or diastolic BP (beta = 0.028, p = 0.281). Age (beta = 0.331, p = 0.0001) and body weight (beta = 0.121, p = 0.0002) were significant independent predictors of systolic BP, and body weight was a significant independent predictor of diastolic blood pressure (beta = 0.207, p < 0.0001). A relationship between alcohol consumption and blood pressure was not apparent in this population of patients following admission to hospital. A positive association between alcohol consumption and blood pressure may not be a universal finding and may be contributed to by a "white coat" effect.
