A comparison and analysis of the Twitter discourse related to weight loss and fitness

More than 30 of the world population is concerned with the problem of overweight. Social media can play a role in human health by offering them correct food patterns and increasing their awareness about different features of appropriate food and diet. Several researches have been carried out on context analysis of social network messages, but there is a paucity of literature on analysis of feelings in tweets and their different geographical locations. This study aims at understanding tweets stated on the amount of reception shown by people in the course of weight loss in a period of 1 month. This study uses cross-sectional and descriptive method to analyze over 2,684,858 of tweets quantitatively. It also compares the emotional aspects present in the tweets. Users, who are active in this domain, are classified into six classes. An investigation and comparison of the number of activities with relation to weight loss has been carried out by searching users� geographical information of social networks in different continents. English tweets have been chosen because of the generality of the English language. After reviewing the previous literature and the results of the analysis on these tweets, using the MALLET software, six classifications were considered for the tweets. The results show that there is a meaningful relation among the extracted parameters in the research. © 2020, Springer-Verlag GmbH Austria, part of Springer Nature

The prevalence of burnout and its relationship with capital types among university staff in Tehran, Iran: A cross-sectional study

Burnout; Social capital; Cultural capital; Economic capital © 2021 The Author(s) Background: Burnout is a job-related syndrome that is common among university staff, and it is caused by various factors. The purpose of this study was to investigate the prevalence of burnout and its relationship with capital types among university staff in Tehran, Iran. Methods: A cross-sectional descriptive-analytical design was used in which 420 staff were randomly sampled from the Iran University of Medical Sciences. For data collection, the researchers used the Burnout Inventory of Maslach and Jackson and Capital Types Questionnaire. The data were entered into SPSS software (Version 22) and analyzed by descriptive and inferential statistics and regressions. Results: The mean burnout of staff was 84.42, and 45.9 of them had high burnout. A significant relationship was found among capital types, work experience, gender, education, and burnout. Multiple linear regressions also showed that independent variables estimated about 32 of the variance of the dependent variable, social capital, gender, and work experience, contributed more to explaining and predicting burnout index. Conclusion: Regarding the relationship between burnout and capital types (economic, cultural, and social), it is necessary to increase capital by increasing cultural activities, staff's knowledge level, income levels, informal groups, and finally, strengthening interpersonal relationships among staff. © 2021 The Author(s

Explaining the reasons for not maintaining the health guidelines to prevent COVID-19 in high-risk jobs: a qualitative study in Iran

Background: Although the workers in many occupations are at the greatest risk of catching and spreading COVID-19 due to assembling and contacting people, the owners of these occupations do not follow COVID-19 health instructions. The purpose of this study is to explain the reasons for not maintaining health guidelines to prevent COVID-19 in high-risk jobs in Iran. Methods: The present study was conducted with a qualitative approach among people with high-risk jobs in Tehran during March and April of 2020. Data were collected through semi-structured interviews with 31 people with high-risk occupations selected by purposeful sampling and snowballing. The data were analyzed using the conventional qualitative content analysis method and MAXQDA-18 software. Guba and Lincoln�s criteria were also used to evaluate the quality of the research results. Results: 4 main categories and 13 sub-categories were obtained, including individual factors (personality traits, lack of self-efficacy, little knowledge of the disease and how to observe health norms related to it, misconceptions about health), structural factors (difficulty of access to health supplies, lack of supportive environment, weak laws and supervision, the poor performance of officials and national media), economic factors (economic costs of living, lack of government economic support), Socio-cultural factors (learning, cultural beliefs, social customs, and rituals). Conclusion: COVID-19 prevention requires intervention at different levels. At the individual level: increasing people�s awareness and understanding about how to prevent COVID-19 and strengthening self-efficacy in observing health norms, at the social level: highlighting positive patterns of observing health issues and training people about the consequences of social interactions during the outbreak of the virus, and at the macro level: strengthening regulatory rules and increasing people�s access to hygienic products and support for the vulnerable must be taken into account. © 2021, The Author(s)

Insight into blood pressure targets for universal coverage of hypertension services in Iran: the 2017 ACC/AHA versus JNC 8 hypertension guidelines

BACKGROUND: We compared the prevalence, awareness, treatment, and control of hypertension in Iran based on two hypertension guidelines; the 2017 ACC/AHA -with an aggressive blood pressure target of 130/80 mmHg- and the commonly used JNC8 guideline cut-off of 140/90 mmHg. We shed light on the implications of the 2017 ACC/AHA for population subgroups and high-risk individuals who were eligible for non-pharmacologic and pharmacologic therapies. METHODS: Data was obtained from the Iran national STEPS 2016 study. Participants included 27,738 adults aged ≥25 years as a representative sample of Iranians. Regression models of survey design were used to examine the determinants of prevalence, awareness, treatment, and control of hypertension. RESULTS: The prevalence of hypertension based on JNC8 was 29.9% (95% CI: 29.2-30.6), which soared to 53.7% (52.9-54.4) based on the 2017 ACC/AHA. The percentage of awareness, treatment, and control were 59.2% (58.0-60.3), 80.2% (78.9-81.4), and 39.1% (37.4-40.7) based on JNC8, which dropped to 37.1% (36.2-38.0), 71.3% (69.9-72.7), and 19.6% (18.3-21.0), respectively, by applying the 2017 ACC/AHA. Based on the new guideline, adults aged 25-34 years had the largest increase in prevalence (from 7.3 to 30.7%). They also had the lowest awareness and treatment rate, contrary to the highest control rate (36.5%) between age groups. Compared with JNC8, based on the 2017 ACC/AHA, 24, 15, 17, and 11% more individuals with dyslipidaemia, high triglycerides, diabetes, and cardiovascular disease events, respectively, fell into the hypertensive category. Yet, based on the 2017 ACC/AHA, 68.2% of individuals falling into the hypertensive category were eligible for receiving pharmacologic therapy (versus 95.7% in JNC8). LDL cholesterol< 130 mg/dL, sufficient physical activity (Metabolic Equivalents≥600/week), and Body Mass Index were found to change blood pressure by - 3.56(- 4.38, - 2.74), - 2.04(- 2.58, - 1.50), and 0.48(0.42, 0.53) mmHg, respectively. CONCLUSIONS: Switching from JNC8 to 2017 ACC/AHA sharply increased the prevalence and drastically decreased the awareness, treatment, and control in Iran. Based on the 2017 ACC/AHA, more young adults and those with chronic comorbidities fell into the hypertensive category; these individuals might benefit from earlier interventions such as lifestyle modifications. The low control rate among individuals receiving treatment warrants a critical review of hypertension services

Liver cancer mortality at national and provincial levels in Iran between 1990 and 2015: A meta regression analysis

Background: Liver cancer is a highly lethal cancer with 5 year survival rate of about 18. This cancer is a leading cause of death in many countries. As there is not a comprehensive population base study on liver cancer mortality rates by cause in national and provincial level in Iran. We aimed to estimate the liver cancer mortality rate, its patterns, and temporal trends during 26 years by sex, age, geographical distribution, and cause. Methods: We used the Iranian death registration system (DRS), in addition to demographic and statistical methods, to address the incompleteness and misclassification and uncertainty of death registration system to estimate annual liver cancer mortality rate. Direct age standardized approach was applied using Iran national population 2015 as a standard population to facilitate the comparison between the provinces. Results: Liver cancer age standardized mortality rate in Iran increased by more than four times from 1.18 (95 uncertainty interval; 0.86 to 1.61) deaths per 100,000 person in 1990 to 5.66 (95 uncertainty interval; 4.20 to 7.63) deaths per 100,000 person in 2015. Male to female age adjusted mortality ratio changed from 0.87 to 1.82 during the 26 years of the study. With increasing age, liver cancer mortality rate increased in both sex and all provinces. At provincial level, the province with highest mortality rate have 2.96 times greater rate compare to the lowest. Generally, about 71 of mortality at national level is due to hepatitis B and C infection. Conclusions: In order to reduce liver cancer mortality rate, it is recommended to control main risk factors including chronic hepatitis infections. Because of the growing rate of mortality from liver cancer, augmenting life expectancy, and increasing number of the elderly in Iran, policy makers are more expected to adopt measures including hepatitis B vaccination or hepatitis C treatment. © 2018, Hepatitis Monthly

Trend of appendicitis mortality at national and provincial levels in iran from 1990 to 2015

Background: Appendicitis is one of the most preventable causes of death worldwide. We aimed to determine the trend of mortality due to appendicitis by sex and age at national and provincial levels in Iran during 26 years. Methods: Data were collected from Iran Death Registration System (DRS), cemetery databanks in Tehran and Esfahan, and the national population and housing censuses of Iran. The estimated population was determined for each group from 1990 to 2015 using a growth model. Incompleteness, misalignment, and misclassification in the DRS were addressed and multiple imputation methods were used for dealing with missing data. ICD-10 codes were converted to Global Burden of Disease (GBD) codes to allow comparison of the results with the GBD study. A Spatio-Temporal model and Gaussian Process Regression were used to predict the levels and trends in child and adult mortality rates, as well as cause fractions. Results: From 1990 to 2015, 6,982 deaths due to appendicitis were estimated in Iran. The age-standardized mortality rate per 100 000 decreased from 0.72 (95 UI: 0.46-1.12) in 1990 to 0.11 (0.07-0.16) in 2015, a reduction of 84.72 over the course of 26 years. The male: female ratio was 1.13 during the 26 years of the study with an average annual percent change of -2.31 for women and -2.63 for men. Among men and women, appendicitis mortality rate had the highest magnitude of decline in the province of Zanjan and the lowest in the province of Hormozgan. In 1990, the lowest age-standardized appendicitis-related mortality was observed in both women and men in the province of Alborz and the highest mortality rate among men were observed in the province of Lorestan. In 2015, the lowest mortality rates in women and men were in the province of Tehran. The highest mortality rates in women were in Hormozgan, and in men were in Golestan province. Conclusion: The mortality rate due to appendicitis has declined at national and provincial levels in Iran. Understanding the causes of differences across provinces and the trend over years can be useful in priority setting for policy makers to inform preventive actions to further decrease mortality from appendicitis. © 2020 The Author (s)

Liver cirrhosis mortality at national and provincial levels in Iran between 1990 and 2015: A meta regression analysis

Background Liver cirrhosis mortality number has increased over the last decades. We aimed to estimate the liver cirrhosis mortality rate and its trends for the first time by sex, age, geographical distribution, and cause in Iran. Method Iranian Death Registration System, along with demographic (Complete and Summary Birth History, Maternal Age Cohort and Period methods) and statistical methods (Spatio-temporal and Gaussian process regression models) were used to address the incompleteness and misclassification and uncertainty of death registration system to estimate annual cirrhosis mortality rate. Percentages of deaths were proportionally redistributed into cirrhosis due to hepatitis B, C and alcohol use based on the data from the Global Burden of Disease (GBD) 2010 study. Results Liver cirrhosis mortality in elder patients was 12 times higher than that in younger patients at national level in 2015. Over the 26 years, liver cirrhosis mortality in males has increased more than that in females. Plus, the percentage of change in age adjusted mortality rate at provincial levels varied between decreases of 64.53 to nearly 17 increase. Mortality rate has increased until 2002 and then decreased until 2015.The province with highest mortality rate in 2015 has nearly two times greater rate compare to the lowest. More than 60 of liver cirrhosis mortality cases at national level are caused by hepatitis B and C infection. The rate of hepatitis B mortality is four times more than that from hepatitis C. Conclusion This study demonstrated an increasing and then decreasing pattern in cirrhosis mortality that could be due to national vaccination of hepatitis B program. However monitoring, early detection and treatment of risk factors of cirrhosis, mainly in high risk age groups and regions are essential. Cirrhosis mortality could be diminished by using new non-invasive methods of cirrhosis screening, hepatitis B vaccination, definite treatment of hepatitis C. © 2019 Rezaei et al.

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries1,2. However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world3 and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health4,5. However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol—which is a marker of cardiovascular risk—changed from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million–4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world
