Influence of life habits in the composition of oral microbiota in obese women

Objectives: To examine whether there are differences between women in the Zagreb County of normal BMI and obese women in the composition of microorganisms in the oral cavity and dietary habits. Subjects and Methods: 66 women participated, 46 women with BMI greater than 30 kg/m² and 20 subjects with normal BMI. The study was approved by the Ethics Committee of the Faculty of Medicine, University of Zagreb. Each of them voluntarily agreed to participate to complete dietary habits survey and also was taken a sample of 2 ml of saliva. Microbiota of saliva - microorganism identification by mass spectrometry was analyzed. For statistical analysis of bacterial culture identification results, Fischer's exact test and Microsoft Excel 2013 were used, and statistically significant values ​​were p less than 0.05. Results: The composition of the oral microbiota have shown the higher incidence of Staphylococcus aureus in obese women (p = 0.0233) and the higher incidence of Streptococcus oralis (p = 0.0439) and Streptococcus mitis (p = 0.0470 ) in women with normal BMI. The number of meals per day is greater than two in 90% of controls and 45.5% of obese, but this is not statistically significant (p = 0.0532). No breakfast is 15.9% obese while everyone in the control group has regular or irregular breakfast, but this is not statistically significant (p = 0.0882). Obese women rated their diet as rich in sweets and snacks (p = 0.0133) and rich in meat and meat products (p = 0.006). Conclusion: Obese women prefer to consume candy and snacks and more meat and meat-derived products. Analysis of oral microbiota showed higher frequency of Staphylococcus aureus in obese women, and women with normal BMI had higher frequency of Streptococcus oralis and Streptococcus mitis.
