title: Tobacco use, Body Mass Index, and Potentially Malignant Disorders Among petrol fillers in Pimpri-Pune (India): A descriptive study.
abstract: BACKGROUND
  Since petrol is combustible and smoking is banned at the petrol pumps, it may be predicted that use of smokeless tobacco is more prevalent among the petrol fillers. Also, smokeless tobacco is a major risk factor for developing oral potentially malignant disorders. The present study was conducted to determine the tobacco use, body mass index (BMI), and potentially malignant disorders among a cohort of petrol fillers and also to evaluate the interaction of tobacco use and BMI with the presence of potentially malignant disorders.
  
  
  METHODS
  The study was conducted at 45 petrol stations located at Pimpri-Pune, India. A descriptive study design was used.
  
  
  METHODS
  Four hundred and ten petrol fillers aged 17-64 years participated in the study. General information and tobacco history was obtained by interview. Height and weight were recorded to obtain BMI. Oral examination was conducted to identify the potentially malignant disorders.
  
  
  METHODS
  Chi-square test, Z test, and logistic regression were used. The level of significance was fixed at 5%.
  
  
  CONCLUSIONS
  It was found that 242 (59.02%) used tobacco in different forms. 77.68% were tobacco chewers, and 8.26% were smokers. Leukoplakia was prevalent among 68.47%, oral submucous fibrosis among 27.45%, and 5.08% had erythroplakia. Age (χ(2) = 11.46, P < 0.05), duration (χ(2) = 17.46, P < 0.05), and frequency of tobacco chewing (χ(2) = 14.16, P < 0.05) were significantly associated with potentially malignant disorders. Tobacco chewing was more prevalent as compared to smoking. It can be concluded that the petrol fillers are at a high risk for developing oral potentially malignant disorders.
