Awareness and Attitudes of Gut Health, Probiotics and Prebiotics in Australian Adults.

The awareness of and attitudes toward gut health, probiotics, prebiotics and factors associated with probiotics use in Australian adults have been explored in a cross-sectional study using CQUniversity's National Social Survey (N = 1,265; 667 females). 58.9% of the participants were probiotics users, who were most commonly identified as female, younger, more educated (Ps < 0.05), with a higher awareness of gut health, and overall healthier lifestyle behaviors (fruits intake, activity, alcohol intake risk) compared to non-users. Maintaining health was the main reason for use. Many (59%) non-users reported a willingness to try probiotics, but only if recommended by a health professional. Probiotics use was associated with awareness of probiotic (odds ratio (OR): 2.02, p < 0.001) and prebiotic (OR:1.59, p = 0.003) terms, natural source of probiotics (OR:2.38, p < 0.001), recommended fruit serves (OR:1.32, p = 0.001), and alcohol score (OR:0.95, p = 0.036). Overall, those who had a healthier lifestyle and better understanding of gut health and probiotics were more likely to use probiotics. Education on gut health and probiotics from health professionals may improve probiotic use, especially in populations that are likely to benefit the most, including those with a specific condition or poor lifestyle.
