Alarm Thresholds for Pertussis Outbreaks in Iran: National Data Analysis

Objectives@#The purpose of the current study was to determine the upper threshold number of cases for which pertussis infection would reach an outbreak level nationally in Iran. @*Methods@#Data on suspected cases of pertussis from the 25th February 2012 to the 23rd March 2018 from the Center for Disease Control and Prevention in Iran was used. The national upper threshold level was estimated using the exponentially weighted moving average (EWMA) method and the Poisson regression method. @*Results@#In total, 2,577 (33.6%) and 1,714 (22.3%) cases were reported in the Spring and Summer respectively. There were 1,417 (18.5%) and 1,971 (25.6%) cases reported in the Autumn and Winter, respectively. The overall upper threshold using the EWMA and the Poisson regression methods, was estimated as a daily occurrence of 8 (7.55) and 7.50 (4.48-11.06) suspected cases per 10,000,000 people, respectively. The daily seasonal thresholds estimated by the EWMA and the Poisson regression methods were 10, 7, 6, 8 cases and 10, 7, 7, 9 cases for the Spring, Summer, Autumn, and Winter, respectively. @*Conclusion@#The overall and seasonal estimated thresholds by the 2 methods were similar. Therefore, the estimated thresholds of 6-10 cases in a day, per 10,000,000 people could be used to detect pertussis outbreaks and epidemics by health policymakers.

Assessment of the risk factors associated with multidrug-resistant tuberculosis in Sudan: a case-control study / 한국역학회지

OBJECTIVES: The emergence of multidrug-resistant tuberculosis (MDR-TB) is a major challenge for the global control of tuberculosis (TB). The aim of this study was to determine the risk factors associated with MDR-TB in Sudan. METHODS: This case-control study was conducted from May 2017 to February 2019. Patients newly diagnosed with MDR-TB were selected as cases, and controls were selected from TB patients who responded to first-line anti-TB drugs. A questionnaire was designed and used to collect data from study participants. Logistic regression was used to evaluate associations between risk factors and MDR-TB infection. The best multivariate model was selected based on the likelihood ratio test. RESULTS: A total of 430 cases and 860 controls were selected for this study. A history of previous TB treatment (adjusted odds ratio [aOR], 54.85; 95% confidence interval [CI], 30.48 to 98.69) was strongly associated with MDR-TB infection. We identified interruption of TB treatment (aOR, 7.62; 95% CI, 3.16 to 18.34), contact with MDR-TB patients (aOR, 5.40; 95% CI, 2.69 to 10.74), lower body weight (aOR, 0.89; 95% CI, 0.87 to 0.91), and water pipe smoking (aOR, 3.23; 95% CI, 1.73 to 6.04) as factors associated with MDR-TB infection. CONCLUSIONS: Previous TB treatment and interruption of TB treatment were found to be the main predictors of MDR-TB. Additionally, this study found that contact with MDR-TB patients and water pipe smoking were associated with MDR-TB infection in Sudan. More efforts are required to decrease the rate of treatment interruption, to strengthen patients’ adherence to treatment, and to reduce contact with MDR-TB patients.

The effects of water-pipe smoking on birth weight: a population-based prospective cohort study in southern Iran / 한국역학회지

OBJECTIVES: Consecutive community health assessments revealed that water-pipe smoking in women and impaired growth in children were among the main health concerns in suburban communities in southern Iran. The aim of the present study was to identify the effects of water-pipe smoking during pregnancy on birth weight.METHODS: Data from a population-based prospective cohort study of 714 singleton live pregnancies in the suburbs of Bandar Abbas in southern Iran in 2016–2018 were used in this study. Data about water-pipe smoking patterns and birth weight were collected by questionnaires during and after the pregnancy. Low birth weight (LBW) was defined as a birth weight below 2,500 g. Statistical analyses were performed using generalized linear models, and the results were presented in terms of relative risk (RR) and 95% confidence intervals (CI).RESULTS: Fifty (8.2%) of the study subjects smoked water-pipe. The adjusted risk of LBW increased 2-fold in water-pipe smokers (adjusted RR [aRR], 2.09; 95% CI, 1.18 to 3.71), and by 2.0% for each 1-year increase in the duration of water-pipe smoking (aRR, 1.02; 95% CI, 0.99 to 1.05).CONCLUSIONS: Our results showed that water-pipe smoking during pregnancy was an important risk factor for LBW in this population sample from southern Iran. The introduction of regulations onto prevent water-pipe smoking and the implementation of community health action plans aiming at empowering women and increasing women's knowledge and awareness regarding the health consequences of water-pipe smoking are proposed.

Associations between diabetes self-management and microvascular complications in patients with type 2 diabetes / 한국역학회지

OBJECTIVES: Diabetes is a major public health problem that is approaching epidemic proportions globally. Diabetes self-management can reduce complications and mortality in type 2 diabetic patients. The purpose of this study was to examine associations between diabetes self-management and microvascular complications in patients with type 2 diabetes. METHODS: In this cross-sectional study, 562 Iranian patients older than 30 years of age with type 2 diabetes who received treatment at the Diabetes Research Center of the Endocrinology and Metabolism Research Institute of the Tehran University of Medical Sciences were identified. The participants were enrolled and completed questionnaires between January and April 2014. Patients' diabetes self-management was assessed as an independent variable by using the Diabetes Self-Management Questionnaire translated into Persian. The outcomes were the microvascular complications of diabetes (retinopathy, nephropathy, and neuropathy), identified from the clinical records of each patient. A multiple logistic regression model was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) between diabetes self-management and the microvascular complications of type 2 diabetes, adjusting for potential confounders. RESULTS: After adjusting for potential confounders, a significant association was found between the diabetes self-management sum scale and neuropathy (adjusted OR, 0.64; 95% CI, 0.45 to 0.92, p=0.01). Additionally, weak evidence was found of an association between the sum scale score of diabetes self-management and nephropathy (adjusted OR, 0.71; 95% CI, 0.47 to 1.05, p=0.09). CONCLUSIONS: Among patients with type 2 diabetes, a lower diabetes self-management score was associated with higher rates of nephropathy and neuropathy.

Evaluation of Pain and Its Effect on Quality of Life and Functioning in Men with Spinal Cord Injury

BACKGROUND: Pain is one of the most important consequences of spinal cord injury (SCI). It may affect several aspects of life, especially the quality of life (QoL). Hence, this study was conducted to establish an understanding of pain and its correlates and effects on patients with SCI in our community. METHODS: In a cross-sectional study, 58 male veterans suffering from SCI were admitted to our center for a regular follow-up. Demographic and SCI-related descriptive information were gathered using a self-reported questionnaire. To evaluate the patients' pain quality and the effect of pain on daily life, a questionnaire in 3 parts of lumbar, cervical and shoulder pain was administered. EuroQoL questionnaire and General Health Questionnaire (GHQ) 12 were also used to assess the patients' QoL. RESULTS: The mean age of the participants was 45.91 +/- 6.69 with mean injury time of 25.54 +/- 5.91. forty-four patients (75.9%) reported pain, including lumbar pain (63%), cervical pain (39%) and shoulder pain (51%). The presence of pain was associated with lower QoL. Patients with lumbar pain reported a significant amount of pain affecting their daily life and this effect was higher in patients with lower GHQ score or anxiety/depressive disorder. CONCLUSIONS: Musculoskeletal pain, is a common complaint in veterans with SCI and is inversely associated with functioning and general health status. Lumbar and shoulder pain affects patient's daily living more than cervical pain.

Risk factors for amputation in patients with diabetic foot ulcer in southwest Iran: a matched case-control study / 한국역학회지

OBJECTIVES: Amputation is a multifactorial complication in diabetic patients. The aim of this study was to determine the risk factors associated with amputation in patients with diabetic foot ulcers. METHODS: This matched case-control study was conducted based on new cases of amputation from March 2012 to November 2014. We selected new cases who had undergone amputation, and the control group was chosen from the cities or areas where the cases resided. Each case was matched with two controls based on the duration of diabetes and location. Conditional logistic regression was used to evaluate the associations between potential risk factors and amputation. RESULTS: A total of 131 cases were compared with 262 controls. The results of the adjusted model showed that sex (odds ratio [OR], 8.66; 95% confidence interval [CI], 2.68 to 27.91), fewer than two hemoglobin A1c (HbA1c) tests per year (OR, 13.97; 95% CI, 4.97 to 39.26), unsuitable shoes (OR, 5.50; 95% CI, 2.20 to 13.77), smoking (OR, 3.44; 95% CI, 1.45 to 8.13), and body mass index (OR, 1.20; 95% CI, 1.03 to 1.41) were associated with amputation in diabetic patients. CONCLUSIONS: The most important factors associated with amputation were females, irregular monitoring of HbA1c levels, improper footwear, and smoking. Developing educational programs and working to ensure a higher quality of care for diabetic patients are necessary steps to address these issues.

Pattern of use of earphone and music player devices among Iranian adolescents

There is no information about the pattern of use of earphones and music players in Iranian adolescents. The aim of this study was to assess the prevalence and pattern of the use of earphone and music player devices as a main risk factor for hearing loss in adolescents of Tabriz city, northwest of Iran. In this cross-sectional study in November 2011, 2,359 high school students were randomly selected and were asked to complete a 20-item questionnaire about the pattern of using earphones and music players. The results showed that 44.3% [confidence interval [CI] 95%: 38.3-50.3] of the respondents had a history of hearing problems that was significantly different between males and females [42.2% of males and 47% of females, p: 0.02]. Notably, 36.8% of the participants stated that they listened to music without any rest or stop. Almost 49.6% [CI 95%: 44.4-54.4] of the students reported listening to 'somewhat loud' [gain setting at 50%] or 'very loud' [gain setting more than 50%] volume level of music. In terms of the kind of earphones, 17.1% of the participants used headphones, 34.8% used earbud-style headphones, 32.3% used supra-aural headphones, and 15.8% of them did not use any type of earphones. Students have risky patterns of using earphones and music-listening devices. Planning educational programs in this domain for adolescents especially in high schools is necessary

Socioeconomic inequalities in nonuse of seatbelts in cars and helmets on motorcycles among people living in Kurdistan province, Iran

The aim of this study was to determine the socioeconomic inequalities in nonuse of seatbelts in cars and helmets on motorcycles in Kurdistan Province, west of Iran, 2009. The data used in this study was collected from the data gathered in non-communicable disease surveillance system [NCDSS] in 2009 in Kurdistan. A total of 1000 people were included in this study. The outcome variable of this study was the nonuse of seatbelts and helmets. The socio-economic status [SES] was calculated based on participants' residential area and assets using Principal Component Analysis [PCA] method. The concentration index, concentration curve, and comparison of Odds Ratio [OR] in different SES groups were used to measure the socioeconomic inequalities using logistic regression. In order to determine the contribution of determinants of inequality, decomposition analysis was used. The prevalence of nonuse of seatbelts in cars and helmets on motorcycles were 47.5%, 95%CI [44%, 55%], respectively. The Concentration index was -0.097, CI [-0.148, -0.046]. The OR of nonuse of seatbelts in cars and helmets on motorcycles in the richest group compared with the poorest group was 0.39, 95%CI [0.23, 0.68]. The results of the decomposition analysis showed that 34% of inequalities were due to SES, 47% were due to residential area, and 12% were due to unknown factors. There is a reverse association between SES and nonuse of seatbelts in cars and helmets on motorcycles. This issue must be considered while planning to reduce traffic accidents injuries

Consanguinity and neonatal death: a nested case-control study

Although numerous studies have found higher rates of abortion and still births following consanguinity [familial marriages], the question of whether consanguinity significantly increases the risk of neonatal death has inadequately been addressed.This study aims to evaluate familial marriage effects on neonatal death in rural areas in Iran. In this nested case-control study, 6900 newbornswho were born in rural areas of Kohgiluyeh and Boyerahmad Province [South-West of Iran] were followed till the end of neonatal period, and neonatal death was the outcome of interest. Subsequently 97 cases and 97 controls were selected in study cohort by using risk set sampling model. Crude and adjusted odds ratios [OR] were estimated by using a conditional logistic regression model. In the final model, prematurity [OR = 5.57], low birthweight [LBW] [OR = 7.68], consanguinity [first cousins] [OR = 5.23], C-section [OR = 7.27], birth rank more than 3 [OR = 6.95] and birthsinterval less than 24 months [OR = 4.65] showed significant statistical association with neonatal mortality [p < 0.05]. According to our findings, after adjusting the effects of other significant risk factors, familial marriage to first cousins is considered as an important risk factor for neonatal death

Factors affecting the survival of patients with gastric cancer undergone surgery at Iran cancer institute: univariate and multivariate analyses

Gastric cancer is the most prevalent cancer among men and the third most prevalent cancer among women in Iran. Its most important reason for death is its belated diagnosis at the advanced stages of the disease. Various factors can be effective on the survival of these patients after surgery, which are the major concern in this study. Data from 330 patients with Gastric cancer who had undergone surgery at Iran Cancer Institute from 1995 to 1999 were analyzed. The Survival Time of patients was determined after surgery and the effect of individual and demographic; clinical and diagnostic; and treatment and post-surgical factors on patients' survival was studied. For data analysis, Kaplan- Meier, Log-Rank test and Proportional Hazards Model were used. The median of survival time was 16.33 months. The one-year, three-year, and five-year survival rates were, 0.66, 0.31, and 0.21. Based on univariate analysis results of age[P<0.001], metastases[P=0.012], disease stage[P=0.016], and number of renewed treatments[P<0.001], as well as multivariate analysis which was used to investigate the simultaneous effect of influencing variables on patients' survival showed that age[61-70:HR=1.40,>70:HR=2.08], marital status[HR=0.39], number of renewed treatments[1:HR=0.54,2:HR=0.30,3:HR=0.22], relapse[HR=1.51], type of gastrectomy [Subtotal: HR=1.12, Distal:HR=0.49, Partial:HR=0.94, Proximal:HR=0.52], liver metastases [HR=1.79], distance metastases[HR=1.84], and disease stage[II:HR=1.28,III:HR=2.12,IV:HR=1.90] variables had a significant effect on patients' survival. Patients who call on doctors in early stages of disease will have a higher survival rate due to early diagnosis whereas disease progression will increase the risk and will decrease the survival. Identifying factors affecting patients' survival and improving diagnostic methods can prevent disease progression and increase survival rate

Inequality of leprosy disability in Iran, clinical or socio-economic inequality: an extended concentration index decomposition approach

Despite significant reduction in global disease prevalence, leprosy still has a high rate of disability while its determinants are unfair and many of them are amendable. The objective of this study was to measure inequality of disability in leprosy in Iran. This was a cross-sectional study [2006-2007] on all living people affected by leprosy registered in W. Azerbaijan province health center, Western North of Iran. The outcome of the study was the socio-economic inequality considering presence or absence of grade 2 disability [G2D] based on the WHO classifications. An extended concentration index decomposition approach was used for analysis. Among 452 cases, 65.3% were male and 67% were affected by the multi bacillary type. Overall G2D was 65.3%. The estimated Concentration Index was -0.0782, showing presence of pro-poor socio-economic inequality of G2D, while extended CI estimation [v = 5] was -0.163. Achievement index with coefficiently = 5] revealed that G2D mean was 16% more than classic mean in the poorest group. The result of decomposition of the existing inequality revealed that, some of the determinants such as receiving mono-therapy, education, urbanization, and bacillus calmette ; guerin [BCG] vaccination had shared contribution [67.4%, 61.8%, 59.2%, and 57.5% respectively]. This study provided new perspective for the health j system to leprosy control considering the significant gap between; rich and poor [inequality] regarding G2D disability, and its effective elements in socio-economic strata. Some effective actions can be considered to reduce the scale of existing inequality

Socioeconomic inequality of non-communicable risk factors among people living in Kurdistan province, Islamic republic of Iran

The most fundamental way to decrease the burden of noncommunicable diseases [NCDs] is to identify and control their related risk factors. The goal of this study is to determine socioeconomic inequalities in risk factors for NCDs using concentration index based on Non-Communicable Disease Surveillance Survey [NCDSS] data in Kurdistan province, Islamic Republic of Iran in 2005 and 2009. The required data for this study are taken from two NCDSSs in Kurdistan province in 2005 and 2009. A total of 2,494 persons in 2005 and 997 persons in 2009 were assessed. Concentration index was used to determine socioeconomic inequality. To assess the relationship between the prevalence of each risk factor and socioeconomic status [SES], logistic regression was used and odds ratio [OR] was calculated for each group, compared with the poorest group. The concentration index for hypertension was -0.095 [-0.158, -0.032] in 2005 and -0.080 [-0.156, -0.003] in 2009. The concentration index for insufficient consumption of fruits and vegetables was -0.117 [-0.153, -0.082] in 2005 and -0.100 [-0.153, -0.082] in 2009. The concentration index for the consumption of unhealthy fat and oil was -0.034 [-0.049, -0.019] in 2005 and -0.108 [-0.165, -0.051] in 2009. The concentration index for insufficient consumption of fish was -0.070 [-0.096, -0.044] in 2005. The concentration index for physical inactivity was 0.008 [-0.057, 0.075] in 2005 and 0.139 [0.063, 0.215] in 2009. In all the cases, the OR of the richest group to the poorest group was significant. Hypertension, insufficient consumption of fruits and vegetables, consumption of unhealthy fat and oil, and insufficient consumption of fish are more prevalent among poor groups. There was no significant socioeconomic inequality in the distribution of smoking, excess weight, and hypercholesterolemia. Physical inactivity was more prevalent among the rich groups of society in 2009. The reduction of socioeconomic inequalities must become a main goal in health-care policies

Residential segregation of socioeconomic variables and health indices in Iran

Measures of segregation are essential tools for evaluation of social equality. They describe complex structural patterns by single quantities and allow the comparison of inequalities over time or between residential places. In many countries, patterns of residential segregation are well described [e.g., South Africa, Great Britain, United States of America]. In this study, for the first time in Iran, we measured residential segregation for some socioeconomic and health variables and described their pair wise correlation. We measured evenness dimension of segregation by generalized dissimilarity segregation index and information theory index and its ordinal equivalent for some determinants of socioeconomic status and health variables using data of last national census in Iran. Segregation indices were computed for 31 socioeconomic variables and four health indices. All the provinces were in the category of low segregation for individual and family disability and death of at least one offspring of mother, but for infant mortality half of the provinces were moderately or highly segregated. For some of socioeconomic variables, many provinces were in the category of moderate, high, or extreme segregation. There was significant correlation between segregation of health indices and some socioeconomic variables. Correlation of segregation of determinants of socioeconomic status with segregation of health indices is an indicator of existence of hot zones of health problems across some provinces. Further studies using multilevel modeling and individual data in health outcomes at individual level and segregation measures at appropriate geographic levels are required to confirm these relations

Excess mortality during heat waves, Tehran Iran: an ecological time-series study

In the past three decades, Tehran, capital of Iran, has experienced warmer summers so we need to determine heat-related mortality to establish appropriate public health activities during hot summers. The aim of this study was to detect heat waves during the last decades and then determine excess mortality in immediate and lagged times. An ecological study based on time-series model was conducted in Tehran for re-cent decade using generalized linear lagged model [GLLM] with Poisson regression in 2001-2011. Maximum daily temperature was heat exposure for death outcome on the same day [lag 0], 3 [lag 01] and also 7 [lag 02] day moving average. Relative risk with 95% confidence was reported to quantify for increasing of daily mortalities for 1[degree sign]C risen exposure. Air pollutants considered as confounders in final model. Total excess mortality during 17 heat waves was 1069 [8.9 deaths/Heat wave days]. All non-external cause of death increased significantly during heat waves [3%-9%] with [RR= 1.03, 95% CI: 1.01, 1.05 and RR=1.09, 95% CI: 1.07, 1.09] and after adjusting for ozone and PM10 raised. Cause-specific deaths [especially circulatory disease] and death among elderly increased during heat waves [especially in the hottest wave]. The largest positive lagged effect of hot temperature although seen during hottest waves for all mortalities. Three waves had the most harvest effect for all categories of mortalities. This study showed excess mortalities resulted from hot temperatures and exacerbated with air pollutants in Tehran in the context of climate change. Forward displacement mortality and lagged mortalities were seen, but our results were not conclusive about the displacement pattern of mortalities

Higher education initiatives for disaster and emergency health in Iran

Iran's health system is expanding the disaster and emergency higher education programs over the country to enhance the capacity of human resources for effective and efficient disaster mitigation, preparedness, response and recovery. In this article we present an overview about the initiatives and progress of disaster and emergency health higher education in Iran. Following the Bam earthquake, in collaboration with the Ministry of Health and Medical Education and National Institute of Health Research, School of Public Health at the Tehran University of Medical Sciences, Iran took the initiative to develop a Master of Public Health [MPH] with disaster concentration in 2006, a PhD in disaster and emergency health in 2011, and a well constructed certificate course in 2008 entitled Disaster Health Management and Risk Reduction [DHMR]. Iran, Kerman and Shahid Beheshti Universities of Medical Sciences and University of Social Welfare and Rehabilitation are other academia that joined this initiative. Regarding the importance of programs evaluation, we have planned for a comprehensive evaluation of MPH and DHMR programs in 2013-4 and the Accreditation and Evaluation Board of Disaster and Emergency Health, based in MOH and ME, is responsible for evaluation of the PhD program in 3-5 years from initiation

Evaluation of tuberculosis situation in economic cooperation countries in 2009; achievement and gaps toward millennium development goals

Evaluating the tuberculosis [TB] status of the Economic Cooperation Organization [ECO] member countries relation to goal 6-c of the third millennium, which includes that TB incidence, prevalence, and death rates should be halved by 2015, compared with their level in 1990. In 2009, we have critically reviewed the countries' Millennium Development Goals [MDGs] reports and extracted the data from the surveillance system and published and unpublished data. The main stakeholders, from both governmental and international organizations in the country have been visited and interviewed by the research team as part of the data validation process. The TB incidence is very heterogeneous among ECO countries, which differ from 21.7 in Iran to 230.7 per 100,000 in Tajikistan. TB incidence [per 100,000] is more than 100 in six countries and is from 50 to 100 in two countries and is less than 30 in two countries. Only in two countries the crude death rate [CDR] is higher than 70%. In seven countries the death rate is higher than 10 per 100,000. Two countries are among the 20 top world countries with the highest tuberculosis burden. There are some signs and signals indicating the bad condition of an ECO member including: incidence of more than 50 per 100000, CDR of less than 70%, death rate more than 10 per 100,000, and rating two member countries among 20 top countries with the highest burden in the world. Iran and Turkey could achieve MDGs by 2015, but if other countries do not prepare urgent intervention programs, they will not be able to fulfill the goals
