TReND publishes supplement on tobacco-related inequalities in low- and middle-income countries

The National Cancer Institute (NCI) and the Tobacco Research Network on Disparities (TReND), funded by the NCI and Legacy, are pleased to announce the release of Research to Reduce Global Tobacco Inequalities, a special supplement to the journal Cancer Causes and Control, published in March 2012.

“A great challenge we face is changing the way public health policies address global health inequalities,” said Dr. Donna Vallone, co-editor of the supplement and Senior Vice President for Research and Evaluation at Legacy. “This extensive collection of manuscripts hopes to serve those who are in power to influence change that will make a difference.”

This supplement includes 11 new studies focusing on the burden of tobacco-related inequalities in low- and middle-income countries (LMIC) in Latin America, Asia, and Africa, many of which have been targeted by the tobacco industry’s deceptive marketing practices. Examples include:

  • Studies conducted in Vietnam and China show how vulnerable populations—including women and children, racial/ethnic minorities and poor persons-are disproportionately affected by secondhand smoke exposure.
  • Data from Southeast Asia show a five-fold mortality increase from oral cancers among tobacco chewers compared to never chewers with a strong and inverse association with education.  
  • In a study conducted in Mexico, participants reported higher levels of overall effectiveness for graphic pictorial health warnings that featured diseased organs or tobacco victims compared to those with symbolic representations or testimonials. 

The issue was edited by Drs. Eliseo J Pérez-Stable, K. Viswanath, Pebbles Fagan, Donna Vallone and Francisco O. Buchting and funded by the National Cancer Institute (NCI). It is a follow-up to the 14th World Conference on Tobacco or Health, Pre-conference workshop, Research to Reduce Tobacco-Related Inequalities: Worldwide Implications for and Exemplars of Tobacco Control (March 8, 2009, Mumbai, India).

All articles are open access. We invite you to review these papers and circulate them to your colleagues. You may access the papers at
