Racial differences in salivary sIgA concentrations in postmenopausal women.
The purpose of this study was to compare sIgA salivary concentrations between Caucasian and African-American postmenopausal women. The age, height, weight and history of hormone replacement therapy were recorded and the BMI was calculated for each individual. Whole, stimulated saliva was assayed for sIgA and total protein. Logistic regression analysis evaluated the relationships between the outcome variables. Total salivary sIgA and adjusted sIgA (adjusted for protein) concentrations were significantly higher in the African-American women (p<0.01). There were significant statistical correlations between sIgA concentrations and race (p<0.01). Our data suggest that racial differences in salivary sIgA concentrations in elderly women could be an important variable for planning future studies utilizing salivary samples as biological markers.
