title: Association between tooth loss and hypertension among a primarily rural middle aged and older Indian adult population.
abstract: Studies in high-income countries have reported associations between tooth loss and hypertension. There is however a lack of evidence on this association from South Asian countries especially India. The current study aimed to assess the association between self-reported tooth loss and hypertension in a primarily rural middle-aged and older Indian population.
  
  
  
  A secondary analysis of cross-sectional data from the Longitudinal Ageing Study of India - pilot survey was conducted on 1,486 adults aged 45 years and above from four states of India. The primary outcome was self-reported hypertension and the main explanatory variable was self-reported tooth loss. Multivariable logistic regression models estimated the association between hypertension and tooth loss after controlling for confounders including age, sex, marital status, area of residence, educational attainment, tobacco use, alcohol use, physical activity, and self-reported diabetes.
  
  
  
  Compared to those without any tooth loss, individuals with partial tooth loss had 1.62 times (95% CI: 1.12-2.35) higher odds of being hypertensive after adjustment of confounders including age, sex, marital status, area of residence, educational attainment, tobacco use, alcohol use, physical activity, and self-reported diabetes. The crude significant association (OR: 2.54; 95% CI: 1.50-4.29) between edentulousness and hypertension became nonsignificant and attenuated after adjustment of potential confounders (fully adjusted model OR: 1.33; 95% CI: 0.72-2.44).
  
  
  
  Partial tooth loss was associated with a higher probability of hypertension among dentate middle-aged and older adults in four states of India.
