Objectives: The oral microbiome plays a central role in oral health. Coffee and tea are popular beverages, and their consumption may benefit health due to their polyphenol content. The impact of these beverages on the oral microbiome is not well understood; we examined associations of coffee and tea consumption with the diversity and composition of the oral microbiome among postmenopausal women.Methods: This cross-sectional analysis used data from 1,124 postmenopausal women who participated in an ancillary study (1997-2001) on periodontal disease within the Women's Health Initiative Observational Study, the Osteoporosis and Periodontal Disease (OsteoPerio) Study. Self-reported frequency of consumption for coffee was categorized as 3 cups/d (n=211), and for tea as <1 cup/w (n=229), ≥1 cup/w to 2 cups/d (n=215). The oral microbiome was assessed in subgingival plaque samples by 16S rRNA gene amplicon sequencing with species-level annotation of the operational taxonomic units (OTUs) based on the Human Oral Microbiome Database. OTUs were transformed using the centered log-ratio (CLR) transformation to account for the compositional data structure and reduce spurious associations with beverage intake. ANOVA was used to examine alpha-diversity (within-sample diversity) and PERMANOVA for beta-diversity (between-sample diversity) of the microbiota across categories of total, regular, and decaf coffee or tea. The alpha-diversity was examined using OTU count, Chao1 Index, and Shannon Index. In addition, the mean CLR-transformed relative abundance of 52 oral bacterial species, previously identified as associated with periodontal disease status in subgingival plaque, were examined using ANOVA across the categories of total coffee and total tea consumption only. Models were adjusted for age, race, education, smoking status, body mass index, diabetes, antibiotic use, dental hygiene behaviors, and dietary sugar intake. For the tea models, we further adjusted for total coffee intake; for the coffee models, we further adjusted for alcohol and total tea intake.Results: There were no statistically significant associations observed between the frequency of consumption of total coffee, regular coffee, total tea, regular tea, or decaf tea intake and the alpha-diversity measures. Intake of decaf coffee consumption was inversely associated with the observed OTU count and the Chao1 Index in adjusted models. For example, the adjusted mean and standard error (SE) for the Chao1 Index was 146.0 (4.33) in those consuming decaf coffee 2 cups/d. The beta-diversity differed across categories of total coffee and regular coffee consumption in the adjusted models (PERMANOVA pcoffee=0.040 and 0.027, respectively), but not for decaf coffee, total tea, regular tea or decaf tea (ptea>0.05). We observed some differences in the relative abundance of bacterial species by beverage intake. The mean relative abundance of Bacteroidaceae_[G-1] _272 (p=0.019), elevated in severe and moderate periodontal disease, and Haemophilus parahaemolyticus (p=0.027), elevated in none/mild periodontal disease, was greater in those who consumed more compared to less total coffee. The mean relative abundance of Porphyromonas gingivalis (p=0.029) and Peptostreptococcaceae[E]_saphenum (p=0.028), both elevated in severe and moderate periodontal disease, was lower in those with greater compared to less total tea intake. Haemophilus parahaemolyticus (p=0.029), elevated in none/mild periodontal disease, had a greater mean relative abundance in those with greater than less total tea intake.Conclusions: In this study of postmenopausal women, we found that the alpha- and beta- diversity of the subgingival oral microbiome differed by coffee, but not tea intake, and that these associations varied by the presence of caffeine in the beverage. The relative abundance of several species of bacteria were associated with the frequency of total coffee and tea consumption.
