At. Merchant et al., INCREASED SEVERITY OF ORAL SUBMUCOUS FIBROSIS IN YOUNG PAKISTANI MEN, British journal of oral & maxillofacial surgery, 35(4), 1997, pp. 284-287
Objective-To investigate the influence of age and sex on the incidence
of severe oral submucous fibrosis (mouth opening 15 mm or less). Desi
gn-Case (severe disease) control (mild disease) study. Setting-Univers
ity hospital, Pakistan. Subjects-147 patients with severe (mouth openi
ng 15 mm or less) and 83 with mild disease (mouth opening 20 mm or mor
e). Main measures-Influence of sex: and age on severity of oral submuc
ous fibrosis. Results-Men were twice as likely as women to have severe
disease (odds ratio (OR) 2.0, 95% confidence interval (CI) of OR 1.15
to 3.47, P=0.02). Men in the 20-39 year age group were 4.8 times as l
ikely as women to have severe disease (OR 5.8, 95% CI 2.15 to 15.5, P=
0.00004). Men aged 40 years or more were 40% less likely to have sever
e disease than women (OR 0.6, 95% CI 0.19 to 1.88, P=0.39), Conclusion
s-Smoking increases the carcinogenic potential of submucous fibrosis,
As men in this population smoke more than women, men with severe oral
submucous fibrosis may develop oral cancer and die younger, Alternativ
ely, young men may consume more areca nut than women.
