Coffee, Tea, and Mammographic Breast Density in Premenopausal Women.

Studies have investigated the associations of coffee and tea with mammographic breast density (MBD) in premenopausal women with inconsistent results. We analyzed data from 375 premenopausal women who attended a screening mammogram at Washington University School of Medicine, St. Louis, MO in 2016, and stratified the analyses by race (non-Hispanic White (NHW) vs. Black/African American). Participants self-reported the number of servings of coffee, caffeinated tea, and decaffeinated tea they consumed. Volpara software was used to determine volumetric percent density (VPD), dense volume (DV), and non-dense volume (NDV). We used generalized linear regression models to quantify the associations of coffee and tea intake with MBD measures. Coffee: ≥1 time/day (ß = 1.06; 95% CI = 0.93-1.21; p-trend = 0.61) and caffeinated tea: ≥1 time/day (ß = 1.01; 95% CI = 0.88-1.17; p-trend = 0.61) were not associated with VPD. Decaffeinated tea (≥1 time/week) was positively associated with VPD in NHW women (ß = 1.22; 95% CI = 1.06-1.39) but not in African American women (ß = 0.93; 95% CI = 0.73-1.17; p-interaction = 0.02). Coffee (≥1 time/day) was positively associated with DV in African American women (ß = 1.52; 95% CI = 1.11-2.07) but not in NHW women (ß = 1.10; 95% CI = 0.95-1.29; p-interaction = 0.02). Our findings do not support associations of coffee and caffeinated tea intake with VPD in premenopausal women. Positive associations of decaffeinated tea with VPD, with suggestions of effect modification by race, require confirmation in larger studies with diverse study populations.

Symptom experience and self-care strategies among healthy, midlife African-American women.

The transition into menopause is an experience that is unique to every woman. This experience can encompass anything from an occasional hot flash to complete and utter distress. Considerable attention is being paid to African-American women as they transition through menopause, but their use of symptom self-care strategies is an area that would benefit from further research. Findings from this study are part of a larger five-year study exploring biopsychosocial health and wellness among diverse midlife women. This report includes identification of symptom prevalence, symptom distress, and self-care strategies used by midlife African-American women during a six-month time period. Prevalent or severe symptoms included fatigue, headaches, cramps, night sweats, and depression. Most self-care strategies were "passive" strategies, such as 'faith," "think," "accept," or "value/believe/forgive self". It is recommended that health-care providers inquire about other symptoms that might accompany classic vasomotor menopausal symptoms and identify "active" self-care strategies that ameliorate specific symptoms.
