A longitudinal study of stress, alcohol, and blood pressure in community-based samples of blacks and non-blacks.

Both alcohol use and stress appear to increase blood pressure. In addition, stress is associated with increased alcohol use. To investigate these relationships, researchers interviewed representative samples of the black and non-black adult household populations in Erie County, New York, in 1986, 1989, and 1993. The results support a causal relationship between stress and alcohol use and point to a number of factors that influence this relationship. Significant relationships between changes in alcohol use and blood pressure were also found. Although the researchers found little evidence for a direct effect of stress on blood pressure, stress related to family life, anxiety, and depression was associated with an increased risk for hypertension.
