Periodontitis is Associated with High/Uncontrolled Blood Pressure among High-Income NHANES Participants
Objectives: Recent findings from our group indicate that a good periodontal health is associated with better systolic blood pressure (BP) profile by about 2.3-3 mmHg and with lower odds of antihypertensive treatment failure. However, disparities in socioeconomic status might affect oral health awareness or healthcare access. We aimed at testing whether the association of periodontitis and BP persists among high-income individuals.
Methods: We examined mean systolic BP(±standard deviation, SD) and the odds ratio (OR) for high/uncontrolled systolic BP (>130 mmHg according to 2017 US hypertension guidelines) in NHANES 2009-2014 high-income participants who underwent complete periodontal examination. Since a poverty-to-income ratio (PIR) score of 1.00 identifies the official federal poverty threshold, we selected participants with PIR≥4 according to CDC. Crude and adjusted (age, gender, ethnicity, body mass index, smoke, glycohemoglobin, cholesterol, triglycerides, creatinine, education) models were generated using R software.
Results: Of 2925 participants with PIR≥4, 2853 had complete data. Compared to participants with periodontitis (n.974, 33.9% women, mean age 58.4±13y, 86.2% non-Hispanic), those without periodontitis (n.1879, 54.5% women, mean age 49.7±13.2y, 89.1% non-Hispanic) had lower mean systolic BP (crude:120.1±15.8 mmHg vs 126.4±18 mmHg, p<0.0001; adjusted: 120.1±6.7 mmHg vs 126.3±6.5 mmHg, p<0.0001), but same mean PIR (4.8±0.3, p=1). Periodontitis was significantly associated with the risk of high/uncontrolled systolic BP compared with the absence of the disease (crude OR:1.95, 95%CI 1.65-2.30, n.2853, p<0.0001; adjusted OR: 1.26, 95%CI 1.04-1.53, n.2732, p=0.019).
Conclusions: In this analysis on high-income individuals, where PIR didn’t differ by periodontal status, the association of periodontitis and high/uncontrolled systolic BP persisted. Other factors might mediate this association.
