Health consequences of the Urmia Lake crisis: the baseline study protocol

Abstract

Introduction Climate change may affect human health due to various mechanisms including overexposure to environmental pollution or dispersed particles. Lake Urmia (LU) drying in recent years has turned into a crisis with particle distribution as its main manifest. It is told that this crisis may affect the health of neighbouring residents. In this paper, we elaborate on a research protocol developed to assess the potential health consequences of LU drying (LUD) by investigating the distribution of physical and mental health conditions/disorders among residents of LU’s surrounding provinces with different exposure levels to LUD outcomes.Methods and analysis The target population of this study is the residents of the LU basin from East Azerbaijan and West Azerbaijan provinces of Iran. A total of 803 households and 2783 people are studied in 86 clusters. Cluster sampling is applied. The weighting of the samples is based on a satellite map of the density of suspended particles such that people living in areas with higher risk have a higher chance of selection. Various types of measurements are done in three major groups including self-reported health, clinical interview/examination and paraclinical assays.Ethics and dissemination In this project, all procedures are in accordance with the ethical standards of the Ethics Committee of Tabriz University of Medical Sciences. Moreover, an informed consent letter is obtained from all participants included in the study. The results from this study will be disseminated in international journals and implemented in the primary care guidelines and national policy documents on managing the potential health consequences of LUD.
