Abstract
Background & Objectives: The recent researches on mortality in Iran in the past 3 decades have obviously emphasized cardiovascular diseases, unintentional injuries, and neoplasms as the most important causes of shortening Iranian’s lives. We investigated the role of these major causes on the mortality patterns in Fars in 2006.
 Methods: The number of registered deaths by age and sex and the distribution of death by cause in Fars in 2006 were derived from the Death Register System of Ministry of Health (MoH). We used the 2006 census to obtain the information on the population exposed to death. The mortality of the people over 5 years of age was estimated and corrected using the Brass Growth Balance method. The mortality rate of the children under the age of 5 was estimated by indirect methods and the data were analyzed using the multi-decrement life table.
 Results: Life expectancy was 70.3 years in Fars, about 69 years in males and 72 years in females, in 2006. The results showed that 3 main causes of death were responsible for reducing life expectancy of about 11 years in men and women in Fars. Detailed results revealed that cardiovascular diseases and unintentional injuries played more important roles in the decrease. Unintentional injuries plays more major role in decreasing life expectancy in males than females.
Conclusion: Special attention should be paid to the risk factors of cardiovascular diseases in both genders and unintentional injuries in males in Fars to reduce the mortality level and increase the life expectancy.

Abstract

Background & Objectives: Measuring the impact of various diseases on Life Expectancy( LE) is an important step toward prioritization in health. The present study was conducted to measure the impact of heart diseases, neoplasm, and respiratory diseases on life expectancy (LE) in 2010.

Methods: Data on death and population for all 22 districts of Tehran were obtained from the main cemetery of Tehran and statistical center of Iran, respectively. Age-specific mortality rates and consequently LE were calculated for all 22 districts and both genders. Finally, the death probability assuming complete elimination of the diseases was calculated and the resulting life tables were obtained.

Results: The LE at birth was estimated 74.6 and 78.4 years for total males and females in Tehran, respectively. The maximum and minimum LE at birth was 80 years in females and 72.7 years in males, respectively. Assuming complete elimination of heart diseases, the LE increased to 82.39 and 85.51 years in males and females, respectively while complete elimination of neoplasm resulted in an increase in LE to 76.27 years in men and 80.49 years in women. Finally, elimination of respiratory diseases increased the LE of men to 75.98 years and the LE of women to 79.97 years.

Conclusion: The results indicated the high impact of the diseases on LE, especially the heart diseases. As a main result, LE will upgrade to more focus on this category.

Abstract
Background and Objectives: Colorectal cancer is considered as one of the most common cancers in the world and Iran. Epidemiological studies are necessary to evaluate the trend of this disease in society. This study aimed to describe the incidence and trend of colorectal cancer in 13 years in Shahroud and Meyami districts, Iran.
Methods: The data were obtained from the population-based cancer registry system at Shahroud University of Medical Sciences, including patients in Shahroud and Meyami districts. The standardized incidence rate (ASR) was calculated based on age and gender, and the 13-year trend from 2010 to 2022 was calculated using joinpoint regression along with the percentage of annual changes.
Results: In general, 543 cases of colorectal cancer were recorded from 2010 to 2022, including 280 (51.6%) males and 263 (48.4%) females. The most recorded cases of this cancer were in 2021 with 54 cases. The Age-standardized mean incidence rate of colorectal cancer in this period was 17.6 per 100,000 people. The ASR of colorectal cancer in males and females was 18.4 (95%CI: 16.2 - 20.6) and 16.8 (95% CI: 14.8 - 18.9), respectively. The annual percent change of ASR during the study period was 2.33% (95% CI: 0.13 – 4.87), indicating an increasing trend.
Conclusion: In the Shahroud and Meyami districts, the incidence rate of colorectal cancer was 17.6 per 100,000 people and has increased relatively over the 13-year study period.
