Association of Recurrent Apthous Stomatitis Types with Body Mass Index Among Pakistani Population

Abstract

Objective: to determine association of BMI in RAS development.

Study Design: Analytic study

Place and Duration of Study: This study was conducted at the Outpatient Department of Punjab Dental Hospital, Lahore from January 2019 to December 2019.

Materials and Methods: Total of 172 RAS patients were enrolled in this study. After taking consent, a self-structured questionnaire was filled out to determine demographic variables, types of RAS and BMI. Data was analyzed by SPSS version 22 for percentage and frequency of variables including age, gender, RAS types and BMI. For association, Chi-square test was used and p-value <0.05 was considered significant.

Results: Our data showed that the mean age was 29.82 (SD=13.19) and female gender was >64%. Minor RAS was the more common type (69.8%), followed by major (24.4%) and herpetiform (5.8%). Among RAS patients, BMI was recorded as 44.2% high, 39.5% normal and 16.3% low. Significant association was observed at 0.008 in RAS types and BMI.

Conclusions: BMI is an important risk factor for RAS. Minor RAS was more common than major and herpetiform.
