Abstract
Background & Objectives: The aim of this study was to investigate the trend of mortality of children under five years old in Kurdistan Province during 2007 to 2011.
Methods: The data of this descriptive-analytical study on deaths and births was collected from provincial deaths registry system and Civil Registration System during 2007 to 2011. The main indicators including under-five mortality, infant mortality, and neonatal mortality rate during the given period were studied. The relationship between variables was calculated using chi-square test.
Results: The neonatal mortality rate changed from 13.5 per thousand live births in 2007 to 12.2 per thousand live births in 2011. During the same period of time, the infant mortality rate and under-five mortality rate declined from 17.1 and 20.2 to 14.9 and 17.4 per thousand live births, respectively. A significant relationship was found between gender and infant mortality. Among the major causes of mortality, prenatal diseases, especially infant diseases, were the most common cause of death in the neonatal period.
Conclusion: According to the results of this study, although there was a reduction in the under-five mortality rate during these years, the observed decline, especially the decline in infant mortality rate, was very slow. There are still some preventable causes of death in children which require more attention by the health system and researchers

Abstract
Background and Objectives: Disorders of height and weight growth are the most important health disorders affecting children younger than two in developing societies. Failure to treat these disorders can lead to the increased mortality and mental, emotional or physical disability. The objective of this study was to investigate the growth trends of children and the factors affecting it.
Methods: This retrospective cohort study was conducted on 2030 children younger than two in Khorramabad, Iran who were selected using stratified and cluster sampling. Based on household records, the weight growth trend was recorded as a four-level variable (decline, stagnation, slowness and desirable) and the the height growth trend was recorded as a three-level variable (stagnation, slowness and desirable); finally, the data were modeled using a longitudinal marginal model and the SAS software version 9.2.
Results: The incidence of at least one decline in the weight growth curve and one stagnation in the height growth curve was 14.2% and 10.4%, respectively. The child’s age and the maternal educational level had a significant effect on the growth trends. However, the sex, parity and the exclusive breastfeeding during the first six months had no significant relationship with the growth trends.
Conclusion: Given the results and the relatively high prevalence of growth disorders among children, it seems that increasing the awareness of low literate women about feeding of the children is the most important approach to manage growth disorders. Additionally, health-care professionals should mostly focus on monitoring the growth of children older than 12 months.

Abstract
Background and Objectives: By identifying the causes of death, interventions can be designed and implemented to reduce the risk factors of different diseases. The aim of this study is to determine the trend of ten leading causes of death in the Islamic Republic of Iran in 2011.
Methods: The study population comprised all deaths recorded in the death registration system of the Ministry of Health and Medical Education (MOHME) from 2006 to 2011. The data related to causes of death reviewed and modified in terms of quality, underreporting of deaths, and garbage codes using the Global Burden of Disease study methods. Finally, the data were analyzed by sex and age groups.
Results: The leading causes of death were cardiovascular diseases (46.12%), cancers and tumors (13.63%) and unintentional injuries (11.55%) in 2011. The 10 leading causes of death in the general population were myocardial infarction, stroke, transportation-related accidents; blood pressure induced heart disease, other cardiovascular diseases, diabetes, chronic pulmonary and bronchial diseases, gastric cancer, other heart diseases and renal failure.
Conclusion: Deaths from non-communicable diseases still account for a large proportion of total deaths. According to the Heath System Reform Plan in Iran and the need for new interventions, it is very important to register the exact causes of death to design service packages and also evaluate the success rate of ongoing interventions.

Abstract
Background and Objectives: Cholera is one of the public health ththat has received attention due to climate change and weather variables. In the current study, the trend of cholera and its epidemics was assessed in the last 50 years in Iran based on climatic variables.
Methods: In a retrospective cohort study, all cholera cases and epidemics of the disease in the country (Iran) were assessed using the registry system of the Center for Communicable Disease Control in the Ministry of Health and Medical education (MOH&ME) from 1964 to 2014. Furthermore, the incidence of cholera was evaluated in 2005-2014 by province. The temperature and rainfall data were obtained from the provincial Meteorological Organization. The correlation coefficient test and mixed-effects binomial regression model were used for data analysis.
Results: A significant positive correlation was found between cholera and rainfall (r = 0.168, P = 0.008). A one-millimeter increase in rainfall increased the incidence of cholera by 10.9% but temperature changes had no effect on cholera outbreaks. The incidence of cholera declined significantly by 14.7% each year from 2005 to 2014. The highest incidence of cholera was reported in Sistan-Baluchestan, Qom, Tehran, Kerman and Hormozgan provinces in a descending order.
Conclusion: In recent years, the the overall incidence of cholera has decreased. The occurrence of cholera is an outcome of rainfall in the previous year. Therefore, increased rainfall increases the number of cholera cases in the next year. However, temperature changes are not related to cholera outbreaks.

Abstract
Background and Objectives: Among non-communicable diseases, endocrine, nutritional, and metabolic diseases have increased in recent decades, especially in developing countries. This study was conducted to evaluate and predict deaths from this group of diseases in Iran
Methods: In this analytical cross-sectional study, the study population comprised all deaths of endocrine, nutritional, and metabolic diseases recorded in the Ministry of Health and Medical Education during the years 2006 to 2016. In order to forecast the trend of cause of death, the Lee Carter model was employed in the demographic package 18/1 of the R software version 3/3/1.
Results: The death rate from endocrine, nutritional, and metabolic diseases increased in all age and sex groups from 2006 to 2015. It was predicted that death rate of this group of diseases would reach 197/71 in 100,000 in the total population, 202/97 in 100,000 women, and 188/99 in 100,000 men in 2035.
Conclusion: Several factors play a role in endocrine and metabolic diseases, one of which is aging and aging population. Considering the change in the age structure of the population of Iran by 2035 and the increase in population’s age, an increasing trend is expected in the mortality rate due to these diseases. Because of this rapid increase, policymakers need to adopt intergovernmental population-based plans and policies in this regard.

Abstract
Background and Objectives: an important problem challenging cesarean section is its extensive use as a common method of delivery. Due to the growing trend of cesarean section in Iran in recent years, the natural delivery promotion program was implemented as one the programs incorporated in the Health System Reform Plan in 2014. In this study, the trend of changes in the percentage of CS delivery in Qom Province following the implementation of this program was evaluated.
Methods: This trend analysis that was performed in all cesarean deliveries in Qom Province from 2005 to 2018 using a joinpoint regression method.
Results: These results showed an annual increase of0.4% in the CS percentage 95% CI: -0.5 to 1.2), which was not statistically significant. A significant decrease was observed in the rate of CS in governmental hospitals. Conversely, in non-governmental hospitals, the percentage of CS increased significantly.
Conclusion: According to the findings of this study, after more than 3 years of implementation of health sector evolution plan, overall implementation of this plan failed to significantly reduce the overall process of cesarean delivery during this period in Qom province and achieve the predetermined goals.

Abstract
Background and Objectives: One of the important basis of health planning in any society is to identify the causes of death and the trend of each cause in that country over time. The purpose of this study is to investigate the trend of youth mortality and causes od death among young population of the Eastern Mediterranean region.
Methods: The present study conducted based on a secondary longitudinal analysis of death data to analyze the trend of youth mortality aged 15-24 and causes of death based on the ICD-10 in Eastern Mediterranean Region between 1990 and 2019. Study data were collected from the IHME Global Burden of Disease (GBD) website and analyzed using descriptive statistical and linear regression analysis. Death rate or cause is the dependent variable and time is the independent variable.
Results: The mortality rate of young people (15 to 24 years old) in all the countries of the Eastern Mediterranean region decreased from 1990 to 2019 except in Syria and Libya. Syria was the only country with a significant increase in the death rate. The most common cause of death was accidents; in general, the death rate related to this cause decreased during 30 years. Among the sub-groups of death causes among young people, the highest rate until 2010 was due to road accidents, which decreased over the study years. From 2010 onwards, death due to self-harm and interpersonal violence had the first rank.
Conclusion: Although a declining trend was observed during the last three decades among young people of Eastern Mediterranean region, deaths due to accidents are still considerable. It seems that the interventions to reduce death due to road accidents were successful; however, any policy and intervention to reduce death due to self-harm and interpersonal violence has a high priority.

Abstract
Background and Objectives: Time trend analysis of factors such as disease and mortality rates is a crucial component of health planning for any community. It allows for a more accurate interpretation of changes over time. This study was conducted to examine the performance of the Joinpoint regression model in analyzing time trends.
Methods: This study aims to first provide a simplified understanding of the Joinpoint regression model and then demonstrate its application on data regarding the 30-year trends of liver cancer mortality due to alcohol consumption in Iran.
Results: The results of the time trend analysis indicate that the age-standardized mortality rate of liver cancer due to alcohol use consumption has decreased by an average of 0.8% per year over the 30-year period in Iran (1990 to 2019). The projections also suggest that this declining trend will continue.
Conclusion: In general, the main advantage of the Joinpoint regression model over other models is its ability to identify periods where significant changes in trends have occurred. Based on the results, the mortality rate of liver cancer due to alcohol use consumption over the 30-year period in Iran can be divided into five periods with different rates of change.
