[Preliminary study of relationship between aggressive periodontitis and obesity].
OBJECTIVE
To investigate the relationship between obesity and aggressive periodontitis (AgP).


METHODS
A total of 151 AgP patients and 94 healthy controls were recruited. Body weight and height were measured, and body mass index (BMI) was calculated. Periodontal clinical parameters were examined. Logistic regression analysis was used to evaluate the association between obesity and AgP.


RESULTS
The mean value of probing depth and clinical attachment loss were (4.8 +/- 2.1) mm and (4.7 +/- 2.8) mm respectively in AgP patients. The numbers of obese and underweight patients in AgP group were 20 and 41 respectively. Five and eight subjects in control group were with BMI values lower and higher than normal range respectively. Both under weight and obesity were risk indicators for AgP, and the OR were 3.60 (P < 0.05) and 4.61 (P < 0.01) respectively.


CONCLUSIONS
Underweight and obesity may be risk indicators for AgP.
