Abstract

RIGOTTO, Raquel Maria et al. Trends of chronic health effects associated to pesticide use in fruit farming regions in the state of Ceará, Brazil. Rev. bras. epidemiol. [online]. 2013, vol.16, n.3, pp.763-773. ISSN 1415-790X.  http://dx.doi.org/10.1590/S1415-790X2013000300019.

The lower valley of Jaguaribe has registered, since the XXI century, the arrival of transnational and regional companies, which led to deep transformations in this region. The increased use of the pesticides is one of the most important ones, being able to cause alterations in human procreation and leading to congenital deformations, besides premature birth and low weight newborns. This article is an ecological study related to the period from 2000 to 2010 in the population of some cities in the state of Ceará, and it was divided in two parts: the first one, a draft of historical series of morbidity and mortality databases and trend verification performed by a simple linear regression; the second one comprehends the calculation of the ratio of rates between cities that are highly exposed to pestiides and the cities selected for comparison, with history of little use of these substances. There was statistically considerable growth tendency (p = 0.026) in the number of hospitalized people with neoplasms. Analyzing the ratios of the rates in these same indicators, it is observed that the rates of hospitalized people with neoplasms were 1.76 times higher in the studied cities than in control cities (p < 0.0010). With regard to to fetal deaths, a statistically considerable increase was observed (p < 0.05) as to the mortality rates in the studied cities. Results suggest there was higher morbidity and mortality caused by neoplasms in the cities with broader use of pesticides, which could be influenced by production, environmental and social transformations associated to the process of deterritorialization induced by the expansion of the agricultural modernization over the morbidity and mortality profile of the population of lower Jaguaribe. This process is a reflex of the production chemical-dependent model adopted by the agribusiness companies, expanding the vulnerability of the country side population.
