IntroductionColorectal cancer (CRC) is one of the most prevalent cancers among Iranian people. The study of spatio-temporal distribution of disease has an important role in the design of disease prevention programmes. The purpose of the current study was to describe the spatio-temporal distribution of CRC in the Iranian military community as a sample of the Iranian population.MethodsIn the current ecological study, all registered cancer cases in the Iranian military community during the period 2007–2016 were considered. To identify hotspots, Getis-Ord Gi statistics were used. All analyses were performed using ArcGIS 10.5 and Excel 2010.ResultsThe highest incidences of CRC in 2007–2008, 2009–2010 and 2011–2012 were recorded in Kermanshah province. The highest incidences of CRC in 2013–2014 were seen in Kermanshah, Ghilan, Tehran and North Khorasan. In 2007–2008 and 2009–2010, hotspots were detected in West Azarbayjan. In 2011–2012, hotspots were detected in Zanjan and Qazvin. In 2013–2014, a hotspot was detected in Qazvin. Finally, West Azerbaijan was the hotspot for CRC in 2015–2016.ConclusionsThe incidence of CRC in men was higher than in women. Also it appeared that North and North West Iran were risk areas for this disease, and so these areas should be considered in the design of disease prevention programme for this cancer type. Additionally, the determination of individual risk factors in the aforementioned geographical areas can play an important role in the prevention of this type of cancer.

Background: Industrialization is the significant cause of death and inability in the most developed and developing countries, and a greater part of nourishing inadequacies and infectious diseases is attibuted to this outcome of modernity. The current study aimed at determining the status of the cardiovascular disease progression in Iran (as a developing country) by assessing the trend of risk factors such as blood pressure (PB), total cholesterol, and body mass index (BMI) from 1980 to 2010.

Background: Under-five mortality and life expectancy are two important health indicators that may be associated with GDP. Thus, the evaluation of the relationship between these indicators can be important in health planning. Objectives: Due to the lack of such study in Iran, the current study aimed to assess the correlation of under-five mortality and life expectancy with GDP in Iran during 1990 -2015. Methods: In this ecological study, all data were extracted from the Gapminder website. The data were analyzed by Pearson correlation coefficient at α = 0.05 as the significance level. All analyses were done using Stata14 and Excel 2010 software.Results: During the study period (1990 -2015), the life expectancy and GDP were increasing and under-five mortality was decreasing. The correlation of GDP with life expectancy and under-five mortality resulted in r = 0.94 (P < 0.001) and r = -0.95 (P < 0.001), respectively. Conclusions: Considering the correlation of GDP with life expectancy and under-five mortality, the share of GDP allocated to the health sector should be increased to improve these indices in Iran.
