Daily Spiritual Experiences, Systolic Blood Pressure, and Hypertension among Midlife Women in SWAN

BACKGROUND: There is reasonable evidence that religious beliefs and activities are associated with lower blood pressure and less hypertension. It is not known if daily spiritual experiences have similar effects. PURPOSE: We examined the relationship between an eight-item version of the Daily Spiritual Experiences Scale (DSES) and systolic blood pressure (SBP) and hypertension. METHODS: With data from 1,060 Caucasian and 598 African-American midlife women participating in Study of Women's Health Across the Nation, in race-stratified models, we used regression equations, logistic regression, and mixed effects regression to estimate the relationship between DSES group and SBP and hypertensive status. RESULTS: We found little difference across DSES groups in adjusted mean SBP for either Caucasian or African-American women. Nor did DSES protect against 3-year increases in SBP, hypertensive status, or incident hypertension. CONCLUSIONS: Daily spiritual experiences do not appear protective for SBP or hypertension in midlife women. Further research should examine factors that condition the religion-BP relationship.
