Abstract
Understanding the associations and possible mechanisms between Cardiorespiratory Fitness (CRF) and residential location is an important focus of public health research. This is a cross-sectional study carried out with 2250 students (6-17 years), from southern Brazil. In addition to age, sex, and body size measurements, we also recorded hemoglobin and platelet count measurements using venous blood samples (10 ml). The CRF was measured using the 6-minute run/walk test, with predictors explored via allometry. Results identified a novel and independent association between the hemoglobin-to-platelet count ratio and children's CRF, after controlling for confounders. We also provide evidence of a possible mechanism for this association, having identified reduced measures of hemoglobin and increased platelet counts observed in children living in urban (vs rural) areas. These results suggest the need for more effective public health practices and policies addressing the built enviroment´s health effects in Brazil and potentially other congested ciries.
期刊介绍:
International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
