Serum Nutrients, Periodontitis and Biological Ageing

Area of Science:

• Nutritional science
• Genetics
• Periodontology

Background:

• Telomere shortening is linked to aging, oxidative stress, and periodontitis.
• Dietary nutrients play a role in chronic inflammatory diseases like periodontitis.
• Investigating nutrient associations with telomere length and periodontitis is crucial for understanding biological aging.

Purpose of the Study:

• To test the hypothesis that blood serum levels of specific vitamins (folate, D, E, cis-β-carotene, β-cryptoxanthin) are associated with telomere lengths and periodontitis.
• To determine if demographic factors (age, sex, smoking, race/ethnicity) modify these relationships.

Main Methods:

• Analysis of laboratory and demographic data from 10,793 participants in the NHANES 1999-2002 survey.
• Assessment of periodontitis status, vitamin levels, telomere lengths, and smoking habits.
• Statistical analysis using ANOVA tests to identify significant associations and interactions.

Main Results:

• Periodontitis showed significant associations with vitamin D, vitamin E, and cis-β-carotene.
• Telomere length was significantly associated with vitamin E and cis-β-carotene.
• Significant interactions were found between folate and sex, vitamin D and periodontitis, vitamin D and race/ethnicity, and vitamin E and sex concerning telomere length.

Conclusions:

• Specific blood nutrients may influence biological aging processes, with periodontitis as a potential co-morbidity.
• Demographic variables such as sex and race/ethnicity can modify the relationships between nutrients, telomere length, and periodontitis.
