Income-related inequality in completed suicide across the provinces of Iran / 한국역학회지

OBJECTIVES@#The aim of this study was to measure income-related inequality in completed suicide across the provinces of Iran.@*METHODS@#This ecological study was performed using data from the Urban and Rural Household Income and Expenditure Survey-2010 conducted by the Iranian Center of Statistics, along with data on completed suicide from the Iranian Legal Medicine Organization in 2012. We calculated the Gini coefficient of per capita income and the completed suicide rate, as well as the concentration index for per capita income inequality in completed suicide, across the provinces of Iran.@*RESULTS@#The Gini coefficients of per capita income and the completed suicide rate in the provinces of Iran were 0.10 (95% confidence interval [CI], 0.06 to 0.13) and 0.34 (95% CI, 0.21 to 0.46), respectively. We found a trivial decreasing trend in the completed suicide incidence rate according to income quintile. The poorest-to-richest ratio in the completed suicide rate was 2.01 (95% CI, 1.26 to 3.22). The concentration index of completed suicide in the provinces of Iran was −0.12 (95% CI, −0.30 to 0.06).@*CONCLUSIONS@#This study found that lower income might be considered as a risk factor for completed suicide. Nonetheless, further individual studies incorporating multivariable analysis and repeated cross-sectional data would allow a more fine-grained analysis of this phenomenon.

[Investigation of Sick Building Syndrome symptoms in inhabitants of Ekbatan town]

Sick Building Syndrome has mostly been examined in office environments than in residential spaces. However, in this research, this problem is surveyed in residential buildings of Ekbatan town. Three hundred and thirty cases were, randomly, chosen from among the inhabitants of Ekbatan town. The questionnaires involved questions about the irritative and mental symptoms. A relation was established between the intensification of these symptoms and the physical conditions of buildings e.g. light, ventilation and other factors such as gender and age. Symptoms of Sick Building Syndrome were positive in 56.4 percent of cases. The strongest symptoms observed among the residents include eye irritation during using the computer [8.8%], sore throat [8.5%] and nose irritation [6.4%] near the garbage shooting. The results showed that the residents of buildings without natural sunlight and appropriate central air-conditioning system with [P= 0.04, OR= 1.60] have higher chances of sick building syndrome than residents of buildings exposed to sunlight and good air-conditioning system [with P=0.001, OR=2.41]. The factors influencing the Sick Building Syndrome in this town include inefficient central air-conditioning system, double windows, improper operation and maintenance of shooting system, improper cleaning, and lack of compressor. The neighboring location of Ekbatan town with the polluted areas such as Azadi's West Terminal and Mehr Abad International Airport is among the factors which contribute to the prevalence of the syndrome, as well
