Background and Objective. Environmental factors are an increasing concern for respiratory health in developing countries. Te
objective of this study was to investigate whether Nigerien people living in cultivated areas have more respiratory symptoms than
those living in pastoral areas. Method. A cross-sectional study was conducted in 2013 in two populations during the rainy season
when land is cultivated. Environmental factors including pesticide use and respiratory symptoms were collected in adults and
children during face-to-face interviews. Multivariate analysis between exposures and symptoms was performed in children and
in adults separately. Results. Te study included 471 adults and 229 children. Overall, none of the households reported the use
of pesticides for agricultural purposes. However, 87.2% reported the use of insecticides at home. Multivariate analysis showed
that people living in agricultural areas compared to those in pastoral areas had an increased risk of respiratory symptoms in
adults (wheezing, dyspnea, sudden shortness of breath, and cough without fever) and in children (cough without fever). Te use
of insecticides showed no efect on respiratory symptoms afer adjustment. Conclusion. Tis frst epidemiological study on the
environment and respiratory health conducted in Niger demonstrates a signifcant relationship between respiratory manifestations
and the agricultural characteristics of the living area. However only the efect of insecticides in the home on respiratory health was
observed.
1. Introduction
In recent decades, environmental factors such as occupa-
tional exposures have become a concern for respiratory
health in the developing countries. Agriculture, the main
industry in these countries, now has recourse to intensive
use of pesticides in order to increase global food production.
Pesticides could be herbicides, fungicides, acaricides, roden-
ticides, and molluscicides [1]. In the meantime, the growing
use of these chemicals has raised questions about the risks for
population health [2]. It is well known that people working
or living on farms or in their vicinity can be exposed to
serious environmental health risks [3–6]. Te World Health
Organization (WHO) considers that environmental factors
are a root cause of an estimated one-quarter of the global
burden of disease, rising to more than one-third in very poor
regions such as Sub-Saharan Africa [7–9]. Te populations
of these countries are more vulnerable because of the lack of
regulations, the absence of health-monitoring systems, and
inadequate information on the precautions required with
regard to environmental factors [3, 6, 9]. Among the 626
million people living in the Sub-Saharan region of Africa,
