Incidence, mortality, and burden of malaria and its geographical distribution in Iran during 2002-2015

Background: This study aimed at estimating the incidence, mortality, burden, and geographical distribution of malaria between 2002 and 2015 in Iran. Methods: DALYs index was used to estimate the burden of malaria. DALYs-related malaria was calculated using a method developed by (WHO) for investigating the Global Burden of Disease (GBD); it was calculated through adding Years of Life Lost (YLLs) due to premature death to Years Lived with Disability (YLDs).The data on the incidence and mortality were collected from the malaria surveillance system in the Center for Communicable Diseases Control (CCDC), Ministry of Health and Medical Education (MOHME). Results: The incidence of malaria had a decreasing trend over the studied period and it reduced from 15378 cases in 2002 to 777 cases in 2015. Overall, 28 cases of mortality were observed between 2002 and 2015. In addition, disease burden decreased from 90.78 DALYs in 2002 to 22.38 DALYs in 2015.Overall, there were 949.2 DALYs due to malaria from 2002 to 2015. The incidence and burden of malaria were not equally distributed among all the provinces in Iran and some areas were suffering from the highest burden of the disease. Conclusion: The incidence and burden of malaria have had a decreasing trend over the years of the study and Iran has little to do in order to eradicate malaria. Since the disease is not equally distributed among various provinces of Iran, health policymakers must direct health resources towards specific areas of the country (Sistan and Baluchistan, Kerman, and Hormozgan) with high concentration of cases of malaria. © 2019, Iranian Journal of Public Health.

Incidence, mortality, and burden of hepatitis B and C and geographical distribution in Iran during 2008-2015

Background: This study aimed at estimating the incidence, mortality, and burden of Hepatitis B (HBV) and Hepatitis C (HCV) viruses and their trends from 2008 to 2015. Methods: The Disability Adjusted Life Year (DALYs) index was applied to calculate the burden of the diseases by age, sex, time, and locations. The incidence and demographic data were obtained from HBV and HCV surveillance system, and the data on natural history was extracted from the cohort studies; moreover, the data on the standard life expectancy was obtained from the Iranian life table 2016. The two values of 0.03 and 21.5 yr were set as the discount rate and mean standard duration of the disease for both types of hepatitis. Results: The burden of HBV decreased from 13735 to 78277.6 yr, but there was an increase in the burden of HCV from 5174 to 14395 yr over the studied period. The burden of both types of hepatitis was higher among males than females. The incidence of HBV increased from 46611 to 22996 cases, and the incidence of HCV increased from 1210 to 3939 cases. The HBV decreased from 1925 to 1394 cases; however, the number of deaths caused by HCV increased from 197 to 583 cases over the studied period. The share of YLLs raised from 5 to 10 for HBV whereas it changed from 23 to 62 for HCV over the studied years. Tehran, Khorasan Razavi, and Golestan had the highest and Chaharmahal and Bakhtiari, Kurdistan, and Kermanshah had the lowest adjusted burden of HBV per 1000 population. Conclusion: Although the incidence, mortality, and burden of HBV declined over the eight studied years, these values increased dramatically for HCV. © 2019, Iranian Journal of Public Health.

Estimating utility value for female genital mutilation

Background: Female genital mutilation/cutting (FGM/C) is a clear violation of women's rights and can have adverse and irreversible health effects as well. Worldwide, more than 200 million women and girls have undergone FGM/C. Utility value of FGM/C has not been estimated yet, so we designed this study to extract the health utility value of FGM/C for the first time in the world. Methods: In a cross-sectional study in Iran, 125 girls and women who underwent FGM/C procedure were examined by the trained midwives in order to determine its type. In addition, a questionnaire was completed for identifying the socio-demographic factors and extracting the health utility of these individuals. Health utility was measured using Time Trade-off method and also to determine the effects of the socio-demographic factors on the health utility a two-limit censored regression model was applied. Results: The mean and median of the health utility of women with FGM/C were 0.971 (SE: 0.003) and 0.968 (IQR: 1-0.95), respectively. Number of non-Traders was 58 (46.4) who reported perfect health utility. However, the mean of health utility among traders was 0.946 (SE: 0.002). Only type 1 (Clitoridectomy) and type 2 (Excision) FGM/C were seen in this study. Women with Type 1 FGM/C had significantly lower health utility value (Mean: 0.968, Median: 0.957) than their type 2 counterparts (Mean: 0.987, Median: 1.00). Moreover, women in the age group of 31-45 years (Mean: 0.962, Median: 0.956), single (Mean: 0.950, Median: 0.954), divorced (Mean: 0.951, Median: 0.950), employed (Mean: 0.959, Median: 0.956), and with supplementary insurance (Mean: 0.962, Median: 0.950) had significantly lower health utility than their counterparts. Conclusion: FGM/C affects physical and psychological well-being of these individuals, resulting in a lack of personal and marital satisfaction, which ultimately leads to a 3 reduction in their health related quality of life. Therefore, preventing from this practice is very important and should be considered by health system policy makers more than before. © 2020 The Author(s)

The health-related quality of life in Iranian patients with COVID-19

Background: COVID-19 is a public health emergency with a high mortality rate and it reduces the patient�s Health-Related Quality of Life (HRQoL) significantly. This effect is measured in the current study. Methods: In a cross-sectional study in Iran, 320 randomly selected treated patients from COVID-19 were studied. To collect the required data, we applied a questionnaire that included socio-demographic factors, clinical characteristics, and questions on the patients� HRQoL. Time trade-off (TTO) approach was used to measure the lost HRQoL attributed to COVID-19. Besides, we applied a two-limit Tobit regression model to determine the effects of the socio-demographic factors on patients� health utility and the visual analogue scale approach was used to estimate the perceived total current health status. Results: The overall mean (SE) and median (IQR) of the health utility values were 0.863 (0.01) and 0.909 (0.21) respectively. These values for the traders (those who were willing to lose a part of their remaining time of life to avoid the disease) were estimated at 0.793 (0.01) and 0.848 (0.17), respectively. The lowest amount of utility value belonged to the elderly (mean (SE) = 0.742 (0.04); median (IQR) = 0.765 (0.42)) and those living in rural areas (mean (SE)) = 0.804 (0.03); median (IQR) = 0.877 (0.30)). The univariate analysis showed that age, place of residence, and household size had a statistically significant effect on health utility. Moreover, findings of the regression analysis indicated that the participants� age and hospitalization status were the key determinants of COVID-19 health utility value. Conclusion: COVID-19 is associated with a substantial and measurable decrease in HRQoL. This decline in HRQoL can be directly compared with that induced by systemic health states. © 2021, The Author(s)

Incidence, mortality, and burden of crimean congo hemorrhagic fever and its geographical distribution in Iran during 2009-2015

Background: This study aimed at estimating the incidence, mortality, burden, and geographical distribution of Crimean Congo Hemorrhagic Fever (CCHF) using Disability Adjusted Life Years (DALYs) in Iran 2009-2015. Methods: CCHF-related DALYs was calculated using a method developed by WHO for the investigation of Global Burden of Diseases (GBD). DALYs was calculated through adding years of life lost due to premature death (YLLs) to years lived with disability (YLDs). To calculate YLD, the average duration of the disease and its disability weight were set at 25 d and 0.613, respectively. The data on the incidence and mortality were collected from the CCHF surveillance system from the governmental section. Results: The highest and the lowest incidence rates of CCHF were observed in 2009 (122 cases) and 2010 (254 cases), respectively. Moreover, the lowest and highest mortality rates were reported in 2009 (20 cases) and 2012 (52 cases), respectively. The mean rate of fatality from CCHF observed between 2009 and 2015 was about 21.1. In addition, the lowest and highest DALYs were observed in 2009 (483 cases) and 2010 (1156 cases), respectively. CCHF incidence, DALYs, and mortality rate over the studied period were higher among males than females. CCHF-related DALYs did not have an equal distribution in all provinces of Iran; some provinces were suffering from a higher burden of the disease. Conclusion: It is recommended to improve the CCHF surveillance system, identify high-risk areas, practice early diagnosis and intervention, develop vaccines, control, and fight tick, and screen livestock to control and prevent the spread of this disease. © 2019, Iranian Journal of Public Health.

Incidence, mortality, and burden of acute watery diarrhea and its geographical distribution in Iran during 2009-2016

Background: Diarrhea is a major cause of public health burden, especially in children under 5 yr of age. This study aimed at estimating the incidence, mortality, burden, and geographical distribution of Acute Watery Diarrhea (AWD) in Iran from 2009 to 2016. Methods: This study was conducted in 2018. The data on the incidence and mortality from 2009 to 2016 was obtained from AWD surveillance system of the Centre for Communicable Diseases Control (CCDC), Ministry of Health and Medical Education (MOHME) of Iran. Disability Adjusted Life Years (DALYs) was used to estimate the burden of AWD. The DALYs-related AWD was calculated using a method developed by WHO. The average duration of the disease and its disability weight, respectively, were set at 5 d (0.0137 years) and 0.093 for all age groups. Results: The incidence of AWD had an ascending trend over the studied period. Forty cases of deaths from AWD were reported. The lowest and highest burdens of AWD, respectively, were 436.1 DALYs in 2010 and 975.9 DALYs in 2015. The incidence and burden of AWD did not have an equal distribution across the country, between the provinces. Conclusion: The incidence of AWD had an ascending trend over the studied period that can be attributed to the improvements in the disease surveillance system. Moreover, the incidence, mortality, and burden of AWD did not have an equal distribution in Iran. Hence, it is recommended to strengthen AWD surveillance system. In addition, it is suggested to adopt proper interventions for controlling the disease in areas with a high burden of AWD. © 2019, Iranian Journal of Public Health. All rights reserved

Distribution of ophthalmologists and optometrists in Islamic Republic of Iran and their associated factors Distribution des ophtalmologues et des optométristes en République islamique d�Iran et facteurs associés

We aimed to determine the distribution of ophthalmic care providers and its correlation with health and socioeconomic status and health system indicators. Data were gathered from the Iran Medical Council and the Iranian Societies of Ophthalmology and Optometry. Concurrent indicators were collected from the Statistical Center of Iran and national studies. A population-adjusted number of combined ophthalmologists and optometrists was used as the main dependent variable. Optometrist/ophthalmologist ratio was 0.9. We had 1 ophthalmologist and 1 optometrist for every 40 000 and 45 000 individuals, respectively. We observed a direct correlation between the number of ophthalmologists, optometrists and life expectancy at the provincial level. Gross provincial income and expenditure and provincial literacy were correlated as well. Provincial unemployment had a negative correlation. Provincial hospital statistics and population density were also significantly correlated. The Islamic Republic of Iran has met the World Health Organization�s desired per capita number of ophthalmologists and optometrists, but there is wide variation in their density. © 2016, World Health Organization.

Incidence, mortality, and burden of severe acute respiratory infection in Iran in 2015

Background: Severe Acute Respiratory Infection (SARI) is responsible for mortality and hospital admissions in millions of people across the world. The present study, for the first time, aimed at estimating the incidence, mortality, and burden of SARI in Iran in 2015. Methods: Disability Adjusted Life Years (DALYs) was used as an index to estimate the burden of SARI. The SARI-related DALYs was calculated using a method developed by the WHO for assessing the Global Burden of Diseases. DALYs are calculated as the sum of the Years Lost due to Disability (YLDs) and the Years of Life Lost (YLLs) due to premature mortality. The data on the incidence and mortality were obtained from the SARI surveillance system of Iran's Ministry of Health and Medical Education. The average duration until remission or death and the disease disability weight were set at four weeks and 0.373, respectively. Results: In 2015, the incidence of SARI was 21309 and 20885 among males and females, respectively. Moreover, 773 males and 737 females died from this disease (Case fatality rate was about 0.035). Total SARI-related DALYs in males and females was 17264 and 16720, respectively. Furthermore, YLLs was responsible for more than 96 of SARI-related DALYs in 2015. Conclusion: There was no significant difference between males and females in terms of the incidence, mortality, and burden of SARI in 2015. Epidemiological data are required to adopt appropriate policies and responses to prevent and control SARI. The incidence, mortality, fatality, and burden of SARI are significant in Iran. It is necessary to develop appropriate strategies, such as vaccination against major pathogens of the disease at least in high-risk groups, strengthening the disease surveillance system, and attracting the attention of policy makers and health authorities of the country. © 2019, Iranian Journal of Public Health.

Path analysis of the relationship between optimism, humor, affectivity, and marital satisfaction among infertile couples

Marital satisfaction is an important factor for establishing a family relationship, feeling satisfied, and living happily together. The aim of the present study was to investigate the relationship between optimism, humor, positive and negative affect, and marital satisfaction among infertile couples. The sample comprised 80 infertile Iranian couples (n = 160) who visited infertility clinics. Participants completed a series of Persian versions of psychometric scales related to optimism (Attributional Style Questionnaire), humor (Humor Styles Questionnaire), marital satisfaction (Enrich Marital Satisfaction Questionnaire), positive affect (PA) and negative affect (NA) (Positive and Negative Affect Schedule). The obtained result of Smart PLS statistical analysis confirmed the significant positive correlation between optimism and humor with marital satisfaction and high PA and low NA. Moreover, the findings also provided an adequate fit of the model. The findings demonstrated that infertile couples high in optimism and humor have higher levels of marital satisfaction and high PA and low PA. Based on the study’s findings, interventions for facilitating optimism and humor among infertile couples are discussed
