BackgroundIn western Sweden, the aim was to study the associations between oral health variables and total and central adiposity, respectively, and to investigate the influence of socio-economic factors SES, lifestyle, dental anxiety and co-morbidity.

MethodsThe subjects constituted a randomised sample from the 1992 data collection in the Prospective Population Study of Women in Gothenburg, Sweden n = 999, 38- > =78 yrs. The study comprised a clinical and radiographic examination, together with a self-administered questionnaire. Obesity was defined as body mass index BMI > =30 kg-m, waist-hip ratio WHR > =0.80, and waist circumference >0.88 m. Associations were estimated using logistic regression including adjustments for possible confounders.

ResultsThe mean BMI value was 25.96 kg-m, the mean WHR 0.83, and the mean waist circumference 0.83 m. The number of teeth, the number of restored teeth, xerostomia, dental visiting habits and self-perceived health were associated with both total and central adiposity, independent of age and SES. For instance, there were statistically significant associations between a small number of teeth <20 and obesity: BMI OR 1.95; 95% CI 1.40-2.73, WHR 1.67; 1.28-2.19 and waist circumference 1.94; 1.47-2.55, respectively. The number of carious lesions and masticatory function showed no associations with obesity. The obesity measure was of significance, particularly with regard to behaviour, such as irregular dental visits, with a greater risk associated with BMI 1.83; 1.23-2.71 and waist circumference 1.96; 1.39-2.75, but not with WHR 1.29; 0.90-1.85.

ConclusionsAssociations were found between oral health and obesity. The choice of obesity measure in oral health studies should be carefully considered.
