Periodontal status and its association with self-reported hypertension in non-medical staff in a university teaching hospital in Nigeria.

BACKGROUND
A growing body of evidence suggests a relationship between periodontal disease and non-communicable systemic diseases with rising prevalence in developing countries, Nigeria inclusive.


OBJECTIVES
To determine the periodontal status and its association with self-reported hypertension among non-medical staff in a university teaching hospital in Nigeria.


METHODS
A cross-sectional study was conducted among non-medical staff using self-administered questionnaires and periodontal clinical examination between July and August 2013. Multivariate analysis was explored to determine the independent variables associated with self-reported hypertension. P values < 0.05 were considered statistically significant.


RESULTS
A total of 276 subjects were enrolled into the study. Shallow pockets (CPI code 3) constituted the predominant periodontal disease (46.7%), calculus (CPI code 2) 46%, bleeding gingiva (CPI code 1) in 3.3% and deep pockets ≥ 6mm (CPI code 4) in 2.2%. Self-reported hypertension was the most prevalent self-reported medical condition (18.1%) and found to be associated with periodontitis, increasing age, lower education, and a positive family history of hypertension.


CONCLUSION
Periodontal disease was highly prevalent in this study. Self-reported hypertension was associated with periodontitis, older age, lower education and a positive family history. Periodic periodontal examination and regular blood pressure assessment for non-medical staff is recommended.
