Increased Outdoor PM_2.5 Concentration Is Associated with Moderate/Severe Anemia in Children Aged 6-59 Months in Lima, Peru.

ABSTRACT: Anemia affects 1.62 billion people worldwide. Although iron deficiency is the main cause of anemia, several other factors may explain its high prevalence. In this study, we sought to analyze the association between outdoor particulate matter PM_2.5 levels with anemia prevalence in children aged 6-59 months residing in Lima, Peru (n = 139,368), one of the cities with the worst air pollution in Latin America. The study period was from 2012 to 2016. Anemia was defined according to the World Health Organization (Hb < 11 g/dL). PM_2.5 values were estimated by a mathematical model that combined data observed from monitors, with satellite and meteorological data. PM_2.5 was analyzed by quintiles. Multiple linear and logistic regressions were used to estimate t
