Abstract
In 1982,4,474 noninstitutionalized residents of Connecticut who were 18 years or older were interviewed as part of the Connecticut High Blood Pressure Program. This cross-sectional study was undertaken to determine the prevalence of hypertension among the 2.1 million adults in the state. Spouse correlations for systolic and diastolic blood pressures were examined in 1,260 white spouse pairs. Upon demonstrating a significant correlation in blood pressure between spouses (r=0.262 for systolic and 0.248 for diastolic, p<0.001), subsequent stepwise multiple regressions were used to determine which aspects of the shared marital environment might influence the spouse concordance. Variables related to each spouse as well as variables reflecting similarity between spouses were analyzed. When spouse concordance in blood pressure was examined controlling for age, obesity, dietary salt intake, socioeconomic status, income, education, occupation, smoking, and exercise of both spouses and similarities in these variables, the correlations between spouses' blood pressures remained significant.
