[Effect of risk factor control policies on oral cancer mortality in Latin America]

Mortality from oral cancer, the prevalence of the main risk factors and the implementation of policies to control current trends and the distribution of data among the countries of Latin America. The objective of this study was to describe the trends of mortality from oral cancer between 2000 and 2017, by sex, in 20 countries in Latin America, and to know the effect of measures to control tobacco consumption and alcohol consumption on the Mortality from oral cancer.

Ecological study that evaluates the relationship between the rates standardized by the age of cancer by oral sex, the prevalence of tobacco consumption and alcohol consumption, and the implementation of control policies. To calculate the annual percentage change of the rates, the Prais-Winsten regression was used; and the effect of measures of control of risk factors on oral cancer mortality is assessed by Spearman correlations.

The greatest decreases in oral cancer mortality were in men in Brazil (APC -7.83, -14.25,-0.93). Mortality from cancer the oral relationship between men and the prevalence of tobacco consumption and alcohol consumption (r = 0.358, r 0.537) (p <0.01), and between the non-implementation of control policies of smoking (r = 0.738) (p= 0.003), the restrictions on the hours and days of sale of alcohol (r = 0.777, p = 0.001), and the states on sponsorship and promotion of alcohol sales (r =0.739 , p =0.040).

The effect of the implementation of control policies is evidenced by a greater relationship with oral cancer mortality in the countries with the least progress in their execution.
