Midlife women's cardiovascular symptoms: A cluster analysis.

Menopausal transition, in which biological and psychosocial changes are caused due to estrogen fluctuations, has been reported to increase cardiovascular risk among midlife women. The purposes of this study were to identify the clusters of midlife women by cardiovascular symptoms and to examine racial/ethnic differences in the clusters. This was a secondary analysis, in which hierarchical cluster and multinomial logistic analyses were conducted with the data (N = 966) collected in two previous studies. Three clusters were adopted: Cluster 1 (high vasomotor and low cardiorespiratory), Cluster 2 (low vasomotor and high cardiorespiratory and high discomfort/pain), and Cluster 3 (high discomfort/pain and high indigestion).
