Association of long-term obesity and weight gain with period
The study suggests that central obesity is related to periodontal inflammation. The research was published in the Journal of Clinical Periodontology.

The study investigates whether obesity, central obesity, and weight gain are associated with periodontal pocketing.

A never-smoking sub-population (n =?725) of the Northern Finland Birth Cohort 1966 was categorized based on body mass index and waist circumference at ages 31 and 46. The categories were combined to define whether the participants stayed in the respective BMI and WC categories or passed on to a higher category during follow-up. A periodontal examination was done at age 46.

- WC was more consistently associated with periodontal pocketing than BMI.

- The RRs for the number of sites with PPD ??4?mm and bleeding PPD ??4?mm in participants with central obesity both at age 31 and at age 46 were 1.7 and 2.1.

- The respective values for participants who had no central obesity at age 31 but had central obesity at age 46 were 1.6 and 1.9.

Of all the studied measures, central obesity appeared to be most strongly associated with the inflammatory condition of the periodontium.
