Abstract

To investigate whether preterm birth (PTB) and extreme birth weights are associated with the prevalence of periodontal disease and tooth loss later in life, we conducted a cross-sectional analysis of 6152 adults (62.3 ± 5.6 years) from the Atherosclerosis Risk in Communities (ARIC) study, who underwent a periodontal examination at Visit 4 (1996-1998). Preterm birth (PTB) (< 37 weeks) and birth weight categories (low birth weight (LBW) < 2.5 kg and high birth weight (HBW) > 4.0 kg) were self‑reported. Periodontal status was assessed via clinical examination and classified using the Periodontal Profile Class (PPC). Multivariable logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) for prevalent periodontal disease (PD) and tooth loss, adjusting for sociodemographic, behavioral, and cardiovascular risk factors. LBW and PTB were associated with increased odds of PD (OR = 1.57, 95% CI 1.15-2.16 and OR = 1.52, 95% CI 1.02-2.27, respectively), but not with tooth loss. Conversely, HBW was not associated with PD but was linked to greater odds of tooth loss (OR = 1.49, 95% CI 1.06-2.07). Adverse birth outcomes are associated with periodontal health in later life, supporting life-course approaches to risk assessment and prevention in both oral and systemic health.
