Association between tooth loss and overweight/obesity among Brazilian adults: the Pró-Saúde Study

Abstract

The aim of this study was to evaluate the association between tooth loss and overweight/obesity in an adult Brazilian population. It is a cross-sectional study comprising 3,930 adults [1,744 men and 2,186 women; median age of 40 y (ranging 20-59); 16.9% obese; 7.3% almost all or all teeth missing]. Data were collected using a selfadministered questionnaire for tooth loss (4 categories), diet, access and use of health services, socioeconomic factors, health habits and behaviors, demographics and anthropometric measurements. Multiple ordinal logistic regressions were performed. In comparison with adults with BMI < 25 kg/m², the overweight (BMI ≥ 25 and < 30kg/m²) and obese individuals (BMI ≥ 30 kg/m²) showed a greater odds of tooth loss (OR = 1.6, 95% CI 1.4-1.9 and OR = 2.1, 95% CI 1.8-2.5, respectively). After adjusting for potential confounders, overweight and obesity showed no statistically significant associations with tooth loss, with OR = 0.8 and OR = 0.9, respectively. The results of this study are consistent with the hypothesis that the association between overweight/obesity and tooth loss can be explained by known, common risk factors.

The Number of Teeth Is Inversely Associated With Metabolic Syndrome: A Korean Nationwide Population‐Based Study

“…This result is in line with that obtained by Zhu and Hollis 12 . However, tooth loss is not associated with being overweight and obesity in Brazilian adults 19 . Chewing discomfort due to tooth loss might affect chewing behaviors and energy intake, which can lead to being overweight or obese.…”

Associations among Obesity, Eating Speed, and Oral Health

“…Although an association between obesity and tooth loss has been reported among adults [26,27], several studies have found no such associations after adjusting for confounding factors [34]. These previous studies did not consider other oral health conditions such as dental caries and periodontal disease.…”

Is there a relationship between obesity and tooth loss and edentulism? A systematic review and meta‐analysis

“…Firstly, different measures and definitions of both tooth loss and edentulism were adopted Obesity and tooth loss G. G. Nascimento et al 595 obesity reviews within the selected studies. Four studies (20,29,31,32) used self-reported tooth loss and two studies used self-reported BMI and tooth loss (28,38). Self-reported tooth loss and BMI are validated measures of tooth loss and obesity (51,52) and are also useful instruments for data collection particularly in large epidemiological studies.…”
