Abstract

Introduction: Acute organophosphorus compounds have induced a lot of human mortalities especially in developing countries. These substances are used widely as insecticides at homes, industry, and agriculture. Aim This study was conducted with the aim of epidemiologic survey on the patients with organophosphates’ poisoning referred to Sina Hospital of Tabriz between 2009 and 2013. Materials and methods This study was a retrospective descriptive research conducted on 551 poisoned patients with organo-phosphorus compounds referred to Tabriz Sina Hospital. The data were collected with filling questionnaires and analyzed by x2-square and regression tests using Exel 2010 and SPSS Ver 16 software packages. Results The results showed that 51.6% of the patients were male and 48.4% of the patients were female. The highest frequency was related to age group 15-25 years with 33.1%. The frequency of patients in relation to their literacy level was mostly among primary school and lower (65.7%). 35.5% of them were single and almost 64.2% of them had committed suicides. The results of X2-square test showed that there was a significant relationship between their jobs and causes of poisoning (p<0.05). Hence, accidental toxicity with organo-phosphorous agents was high among farmers. Frequency of poisoning with these agents was higher in spring and summer compared to autumn and winter. The highest level of suicide with organophosphates was seen in East Azerbaijan province (66.6%). Conclusion It is recommended to limit access of high risk people, particularly farmers, to these substances by offering specific cards confirmed by competent individuals in agricultural affairs. Purchase of poisons and returning of the remainders after end of spraying, could reduce the probability of misuse and suicide.
