Association of obesity and weight gain with alveolar bone loss: Results of the Northern Finland Birth Cohort 1966 study

Abstract

Aim: To investigate whether long-term obesity, long-term central obesity and weight gain are associated with alveolar bone loss. Materials and Methods:A sub-population (n = 1318) of the Northern Finland Birth Cohort 1966 was categorized based on body mass index (BMI: normal weight, overweight and obesity) and waist circumference (WC: no central obesity, central obesity) at ages 31 and 46. These categories were combined to define whether the participants stayed in the same categories or passed on to a higher category (weight gain).Alveolar bone level (BL) data were collected at age 46. Results:The associations of long-term obesity and weight gain with BL ≥ 5 mm were stronger in smokers than in the total population and in never smokers. Males who passed on to higher BMI and WC categories showed a higher likelihood for BL ≥ 5 mm (range in relative risks [RRs] 1.3-2.2) than males who stayed in the same categories (range in RRs 0.7-1.1). The associations with BL ≥ 5 mm were weak or non-existent in females. Conclusions:The relation between obesity and periodontal diseases seems more complex than previously presumed. The role of gender and smoking should be taken into account in future studies.

Factors Associated with the Extent of Clinical Attachment Loss in Periodontitis: A Multicenter Cross-Sectional Study

“…However, it is still controversial in Latin American populations [11][12][13]. Likewise, an association between periodontitis and putative risk factors such as high levels of stress [13][14][15] and obesity [16][17][18] has been reported.…”
