Objectives: Obesity is an important risk factor for chronic diseases and can also result in greater mortality. The aim of this longitudinal study was to investigate whether poor oral health acts as a risk factor for obesity as indicated by body mass index (BMI) and waist circumference (WC). Methods: We included in this analysis all participants who volunteered in a cohort study entitled 'Carlos Barbosa Cohort Study—CBCS' in the city of Carlos Barbosa, Southern Brazil. The interview questionnaire comprised socio‐demographic information, behavioural questions and medical history. Oral examinations and anthropometric assessments were carried out. The outcome was obesity measured by both BMI (≥30 kg/m2) and WC (>0.80 for women and >0.94 for men). Variables were collected longitudinally. Those associated with the outcome and epidemiologically relevant to the conceptual framework participated in the analysis and were adjusted for socio‐demographic, behavioural, general and oral health conditions. Results: Six hundred and thirty‐three independently living elders participated. The baseline mean age was 67.5 ± 6.1 years. Individuals who never visited a dentist (OR = 3.02, 95% CI: 1.25‐7.26) as well as participants who needed a dental prosthesis in the lower arch (OR = 4.38, 95% CI: 1.34‐14.32) were more likely to be obese, through BMI and WC measures, respectively. Edentulous participants with complete dentures in both arches (OR = 0.23, 95% CI: 0.06‐0.84) and those who perceived their oral health as unsatisfactory (OR = 0.41, 95% CI: 0.19‐0.88) had a lower likelihood of being obese, according to BMI and WC measures. Conclusions: Older persons with poor oral health may be at risk for general and central obesity, a relationship that may have important clinical implications. [ABSTRACT FROM AUTHOR]
