Secondhand Smoke Exposure in Primary School Children: A Survey in Dhaka, Bangladesh.

ABSTRACT:

Introduction

We report on second-hand smoke (SHS) exposure based on saliva cotinine levels among children in Bangladesh-a country with laws against smoking in public places.

Methods

Of these, 479 saliva samples were found sufficient for cotinine testing, of which 95% (453/479) were positive for recent SHS exposure.
