Wealth and cardiovascular health: a cross-sectional study of wealth-related inequalities in the awareness, treatment and control of hypertension in high-, middle- and low-income countries. Int J Equity Health 2016; 15:199. [PMID: 27931255 PMCID: PMC5146857 DOI: 10.1186/s12939-016-0478-6] [Citation(s) in RCA: 58] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2016] [Accepted: 11/10/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Effective policies to control hypertension require an understanding of its distribution in the population and the barriers people face along the pathway from detection through to treatment and control. One key factor is household wealth, which may enable or limit a household's ability to access health care services and adequately control such a chronic condition. This study aims to describe the scale and patterns of wealth-related inequalities in the awareness, treatment and control of hypertension in 21 countries using baseline data from the Prospective Urban and Rural Epidemiology study. METHODS A cross-section of 163,397 adults aged 35 to 70 years were recruited from 661 urban and rural communities in selected low-, middle- and high-income countries (complete data for this analysis from 151,619 participants). Using blood pressure measurements, self-reported health and household data, concentration indices adjusted for age, sex and urban-rural location, we estimate the magnitude of wealth-related inequalities in the levels of hypertension awareness, treatment, and control in each of the 21 country samples. RESULTS Overall, the magnitude of wealth-related inequalities in hypertension awareness, treatment, and control was observed to be higher in poorer than in richer countries. In poorer countries, levels of hypertension awareness and treatment tended to be higher among wealthier households; while a similar pro-rich distribution was observed for hypertension control in countries at all levels of economic development. In some countries, hypertension awareness was greater among the poor (Sweden, Argentina, Poland), as was treatment (Sweden, Poland) and control (Sweden). CONCLUSION Inequality in hypertension management outcomes decreased as countries became richer, but the considerable variation in patterns of wealth-related inequality - even among countries at similar levels of economic development - underscores the importance of health systems in improving hypertension management for all. These findings show that some, but not all, countries, including those with limited resources, have been able to achieve more equitable management of hypertension; and strategies must be tailored to national contexts to achieve optimal impact at population level.

Abstract
BACKGROUND Several studies reported a U-shaped association between urinary sodium excretion and cardiovascular disease events and mortality. Whether these associations vary between those individuals with and without hypertension is uncertain. We aimed to explore whether the association between sodium intake and cardiovascular disease events and all-cause mortality is modified by hypertension status. METHODS In this pooled analysis, we studied 133,118 individuals (63,559 with hypertension and 69,559 without hypertension), median age of 55 years (IQR 45-63), from 49 countries in four large prospective studies and estimated 24-h urinary sodium excretion (as group-level measure of intake). We related this to the composite outcome of death and major cardiovascular disease events over a median of 4.2 years (IQR 3.0-5.0) and blood pressure. FINDINGS Increased sodium intake was associated with greater increases in systolic blood pressure in individuals with hypertension (2.08 mm Hg change per g sodium increase) compared with individuals without hypertension (1.22 mm Hg change per g; pinteraction<0.0001). In those individuals with hypertension (6835 events), sodium excretion of 7 g/day or more (7060 [11%] of population with hypertension: hazard ratio [HR] 1.23 [95% CI 1.11-1.37]; p<0.0001) and less than 3 g/day (7006 [11%] of population with hypertension: 1.34 [1.23-1.47]; p<0.0001) were both associated with increased risk compared with sodium excretion of 4-5 g/day (reference 25% of the population with hypertension). In those individuals without hypertension (3021 events), compared with 4-5 g/day (18,508 [27%] of the population without hypertension), higher sodium excretion was not associated with risk of the primary composite outcome (≥ 7 g/day in 6271 [9%] of the population without hypertension; HR 0.90 [95% CI 0.76-1.08]; p=0.2547), whereas an excretion of less than 3 g/day was associated with a significantly increased risk (7547 [11%] of the population without hypertension; HR 1.26 [95% CI 1.10-1.45]; p=0.0009). INTERPRETATION Compared with moderate sodium intake, high sodium intake is associated with an increased risk of cardiovascular events and death in hypertensive populations (no association in normotensive population), while the association of low sodium intake with increased risk of cardiovascular events and death is observed in those with or without hypertension. These data suggest that lowering sodium intake is best targeted at populations with hypertension who consume high sodium diets.

Abstract
BACKGROUND Few investigators have reported case fatality and disability of Iranian patients with stroke. This study was designed to collect morbidity and case fatality data of hospitalized patients with stroke, and stroke care quality in Isfahan, Iran. METHODS From 2006 to 2011, from overlapping sources (discharge diagnoses, attending physicians, and hospitalization wards), all hospitalized patients with possible strokes were enrolled in the study, their hospital records were summarized by experienced personnel and reviewed by a neurologist with stroke experience. Patients were followed by phone calls or visited to their addresses and their 28(th) day functional status was checked by translated modified Rankin Scale (mRS). Forms and methods were derived from the World Health Organization (WHO) Monitoring Trends and Determinants in Cardiovascular Disease and STEPS projects. RESULTS A total of 9487 patients were identified to suffer from stroke. Their ages' mean was 68.98 ± 13.63 years, and 50.0% were females. In hospital, case fatality was 16.5% and the 28(th) day case fatality was 25.6%. The greatest case fatality was among intracerebral hemorrhage (ICH) patients and the least among ischemic stroke (IS) ones. Case fatality was greater among female and older patients and those with the previous history of stroke. Among survivors, only 26.9% were functionally independent (mRS < 3) which was the greatest among subarachnoid hemorrhage (SAH) patients and least among ICH patients. None of the patients were admitted to specific stroke units or received thrombolytic therapy. CONCLUSION The hospitalized patients with stroke in Isfahan have unfavorable outcome compared with their mates in developed countries. A low quality of stroke care may be responsible, and urgent attention is needed.

Abstract
OBJECTIVE To examine and compare tobacco marketing in 16 countries while the Framework Convention on Tobacco Control requires parties to implement a comprehensive ban on such marketing. METHODS Between 2009 and 2012, a kilometre-long walk was completed by trained investigators in 462 communities across 16 countries to collect data on tobacco marketing. We interviewed community members about their exposure to traditional and non-traditional marketing in the previous six months. To examine differences in marketing between urban and rural communities and between high-, middle- and low-income countries, we used multilevel regression models controlling for potential confounders. FINDINGS Compared with high-income countries, the number of tobacco advertisements observed was 81 times higher in low-income countries (incidence rate ratio, IRR: 80.98; 95% confidence interval, CI: 4.15-1578.42) and the number of tobacco outlets was 2.5 times higher in both low- and lower-middle-income countries (IRR: 2.58; 95% CI: 1.17-5.67 and IRR: 2.52; CI: 1.23-5.17, respectively). Of the 11,842 interviewees, 1184 (10%) reported seeing at least five types of tobacco marketing. Self-reported exposure to at least one type of traditional marketing was 10 times higher in low-income countries than in high-income countries (odds ratio, OR: 9.77; 95% CI: 1.24-76.77). For almost all measures, marketing exposure was significantly lower in the rural communities than in the urban communities. CONCLUSION Despite global legislation to limit tobacco marketing, it appears ubiquitous. The frequency and type of tobacco marketing varies on the national level by income group and by community type, appearing to be greatest in low-income countries and urban communities.

Abstract
BACKGROUND This study aimed to find the influence of education level on the trends of changes of these risk factors among a great sample of Iranian population. MATERIALS AND METHODS This cross-sectional study is a secondary analysis of Isfahan Healthy Heart Program (IHHP). Blood samples were taken to determine the lipid levels including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), low levels of high-density lipoprotein cholesterol (HDL-C), and triglycerides. Education categorized based on training system in Iran as 1-5, 6-12, and more than 12 years training. RESULTS The prevalence of diabetes was higher among illiterate participants in both areas. Hypertension was more prevalent in illiterate subjects (2001; 44.0% and 2007; 46.3%) in intervention area (P < 0.001). Dyslipidemia was more prevalent among illiterate people (P < 0.001). In the intervention, illiterates have higher BMI in both 2001 and 2007 (P < 0.001). The prevalence of current smoking was the highest in education level range 6 to 12 years and was steadily decreased in higher education levels (P < 0.001). Subjects with 6-12 years of education have more unhealthy nutritional habits in both areas. In 2001, subjects with 12 years of education or more had more physical activity than other groups (P < 0.001), whereas, in 2007, subjects with 6-12 years of education were more active (P < 0.001). CONCLUSION Although the prevalence of diabetes, hypertension obesity, and dyslipidemia are more in illiterate subjects and prevalence of diabetes and hyperlipidemia was sharply decreased with education level, it seems that well educated participants have higher daily physically activity compared with those who have lower education without considering the place or residency.

Abstract
BACKGROUND It is now hypothesized whether restricted salt intake can be a potential precursor to renal dysfunction in mild hypertension state. We aimed to study the association between salt intake and renal function in patients with mild hypertension. METHODS One hundred consecutive hypertensive Iranian patients (with systolic blood pressure 140-160 mmHg and/or diastolic 90-100 mmHg) who were referred to the hypertension research center, Isfahan, Iran, between 2011 and 2014 for screening of hypertension were assessed. Renal function was assessed by measuring serum creatinine (Cr) and creatinine clearance (CrCl). Daily salt intake was assessed on the basis of 24 h urinary sodium excretion. RESULTS There was no association between the amounts of sodium intake and serum Cr concentration (r = 0.138, P = 0.174), however, an association was revealed between sodium intake and value of CrCl (r = 0.303, P = 0.003). Multivariable linear regression model showed that sodium intake could effectively predict renal function assessed by CrCl (Beta = 0.070, P = 0.016). CONCLUSION There is an association between sodium intake and reservation of renal function in mild hypertension state and thus by restriction of dietary salt intake, reserving renal function, and preventing appearance and progression of renal insufficiency in higher degrees of hypertension can be facilitated.

IRANIAN JOURNAL OF VETERINARY RESEARCH 2015; 16:75-77.

Abstract
Currently, somatic cell count (SCC) and bacterial culture are considered as the gold standard of detecting subclinical Mastitis. Mastitis leads to proliferation of lymphocytes in the supramammary lymph nodes and subsequent enlargement of ipsilateral lymph node. Ultrasonography can be used to survey these changes. A portable ultrasound machine with a 2-5 MHz convex transducer was used to identify the supramammary lymph node size in 35 cows in a herd with chronic Staphylococcus aureus mastitis. After pre-milking udder preparation, a California mastitis test (CMT) was performed and individual milk samples were taken from each quarter for bacterial culture and somatic cell count (SCC) in accordance with NMC recommendations. The mean length (range 5.77-12.90 cm) and width (range 2.07-7.41 cm) of the lymph node were 9.2 and 4.03 cm, respectively. There was a positive correlation between lymph node size (length and depth) and culture of milk samples on ipsilateral quarters. Also, there was a significant difference correlation between CMT or mean log SCC of each side and size of supramammary lymph node in the same side. This study showed significant changes in supramammary lymph node dimensions in mastitis cases, so ultrasonography of this lymph node is probably a useful method for mastitis detection, especially in situations that test on milk is impossible.

Abstract
Background: Cardiovascular diseases (CVDs) are the leading cause of death in Iran. The present study evaluated the 7-year incidence of CVD risk factors among the participants of Isfahan cohort study (ICS). Materials and Methods: ICS was a longitudinal study on adults over 35 years of age from the urban and rural areas in three counties in central Iran. Data on clinical examination and blood measurements were collected in 2001. Subjects were followed and similar data were collected in 2007. Cumulative incidence was calculated through dividing new cases of each risk factor by the population free of that risk factor at baseline. Incidence proportion was determined for major CVD risk factors including hypertension (HTN), hypercholesterolemia (HC), hypertriglyceridemia (HTg), obesity, diabetes mellitus (DM), metabolic syndrome (MetS), and smoking. Results: A total number of 6323 adults free of CVDs were recruited. After 7 years of follow-up, 3283 individuals were re-evaluated in 2007. The participants’ age was 49.2 ± 10.3 years in 2001 (mean ± SD). The 7-year cumulative incidence of HTN, HC, HTg, overweight, obesity, DM, MetS, and smoking was 22.8%, 37.4%, 28.0%, 26.3%, 7.4%, 9.5%, 23.9%, and 5.9% in men and 22.2%, 55.4%, 33.5%, 35.0%, 18.8%, 11.3%, 36.1%, and 0.7% in women, respectively. Among those with overweight or obesity, 14.7% of men and 7.9% of women decreased their weight up to the normal level. Conclusions: The present study revealed a high incidence of CVD risk factors especially dyslipidemia, obesity, MetS and HTN. Therefore, the application of life-style modification interventions seems necessary.

Abstract
BACKGROUND Health volunteers can have a great effect by training the population about prevention of cardiovascular disease (CVD) and lifestyle modification. This study evaluated the health volunteers' knowledge following the Isfahan Healthy Heart Program (IHHP) that was performed between 2000 and 2006. MATERIALS AND METHODS In this study, 491 females were selected among health volunteers in the Isfahan and Najafabad districts as intervention areas and Arak as a reference area through 2000-2001 until 2006. They participated in training courses on CVD, its complications, methods of prevention of risk factors control as well healthy lifestyle promotion. The health volunteers' level of knowledge was assessed before and after training. RESULTS Before intervention, there was no significant difference between the scores of health volunteers in the intervention and the control regions in terms of knowledge about recognizing the symptoms, complications and prevention of CVD and relevant risk factors and healthy lifestyle. However, their knowledge scores increased significantly in the fields of CVD (β = 0.13, P = 0.04), hypertension (β = 0.18, P = 0.009), healthy nutrition (β = 0.19, P = 0.007), appropriate physical activity (β = 0.17, P = 0.01) and dealing with stress (β = 0.16, P = 0.02) after trainings. CONCLUSION The 6 year interventional program of IHHP showed that training health volunteers on prevention of CVD, their risk factors and modification of lifestyle continued to be effective even in a long time.

Abstract
BACKGROUND Brewer's yeast may have beneficial effects on insulin receptors because of itsglucose tolerance factor in diabetic patients. This study was conducted to investigate the effects of brewer's yeast supplementation on glycemic indices in patients with type 2 diabetes mellitus. METHODS In a randomized double-blind controlled clinical trial, 84 adults (21 men and 63 women) aged 46.3 ± 6.1 years old with type 2 diabetes mellitus were recruited and divided randomly into two groups: Supplement group receiving brewer's yeast (six 300mg tablets/day, total 1800 mg) and control group receiving placebo (six 300mg tablets/day) for 12 weeks. Body weight, height, body mass index, food consumption (based on 24h food record), fasting blood sugar (FBS), glycosylated hemoglobin, insulin sensitivity, and insulin resistance were measured before and after the intervention. Data analysis was performed using the Statistical Package for Social Sciences (version 18.0). RESULTS The changes in FBS, glycosylated hemoglobin, and insulin sensitivity were significantly different between the two groups during the study (respectively P < 0.001, P < 0.001, P = 0.02 independent sample t-test). There was a significant difference in FBS, glycosylated hemoglobin, and insulin sensitivity at the end of the study between the two groups after removing the effects of baseline values (respectively P = 0.002, P < 0.001, P = 0.02, analysis of covariance). Changes in body mass index, 24h food record, insulin resistance were not significant. CONCLUSIONS Dietary supplementation with brewer›s yeast besides the usual treatment of diabetes can ameliorate blood glucose variables in type 2 diabetes mellitus.

Abstract
IMPORTANCE Hypertension is the most important preventable cause of morbidity and mortality globally, yet there are relatively few data collected using standardized methods. OBJECTIVE To examine hypertension prevalence, awareness, treatment, and control in participants at baseline in the Prospective Urban Rural Epidemiology (PURE) study. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional study of 153,996 adults (complete data for this analysis on 142,042) aged 35 to 70 years, recruited between January 2003 and December 2009. Participants were from 628 communities in 3 high-income countries (HIC), 10 upper-middle-income and low-middle-income countries (UMIC and LMIC), and 4 low-income countries (LIC). MAIN OUTCOMES AND MEASURES Hypertension was defined as individuals with self-reported treated hypertension or with an average of 2 blood pressure measurements of at least 140/90 mm Hg using an automated digital device. Awareness was based on self-reports, treatment was based on the regular use of blood pressure-lowering medications, and control was defined as individuals with blood pressure lower than 140/90 mm Hg. RESULTS Among the 142,042 participants, 57,840 (40.8%; 95% CI, 40.5%-41.0%) had hypertension and 26,877 (46.5%; 95% CI, 46.1%-46.9%) were aware of the diagnosis. Of those who were aware of the diagnosis, the majority (23,510 [87.5%; 95% CI, 87.1%-87.9%] of those who were aware) were receiving pharmacological treatments, but only a minority of those receiving treatment were controlled (7634 [32.5%; 95% CI, 31.9%-33.1%]). Overall, 30.8%, 95% CI, 30.2%-31.4% of treated patients were taking 2 or more types of blood pressure-lowering medications. The percentages aware (49.0% [95% CI, 47.8%-50.3%] in HICs, 52.5% [95% CI, 51.8%-53.2%] in UMICs, 43.6% [95% CI, 42.9%-44.2%] in LMICs, and 40.8% [95% CI, 39.9%-41.8%] in LICs) and treated (46.7% [95% CI, 45.5%-47.9%] in HICs, 48.3%, [95% CI, 47.6%-49.1%] in UMICs, 36.9%, [95% CI, 36.3%-37.6%] in LMICs, and 31.7% [95% CI, 30.8%-32.6%] in LICs) were lower in LICs compared with all other countries for awareness (P <.001) and treatment (P <.001). Awareness, treatment, and control of hypertension were higher in urban communities compared with rural ones in LICs (urban vs rural, P <.001) and LMICs (urban vs rural, P <.001), but similar for other countries. Low education was associated with lower rates of awareness, treatment, and control in LICs, but not in other countries. CONCLUSIONS AND RELEVANCE Among a multinational study population, 46.5% of participants with hypertension were aware of the diagnosis, with blood pressure control among 32.5% of those being treated. These findings suggest substantial room for improvement in hypertension diagnosis and treatment.

BACKGROUND This study evaluated the outcome of a comprehensive, community-based healthy lifestyle program on cardiometabolic risk factors. The Isfahan Healthy Heart Program (IHHP) was a comprehensive action-oriented, multi-component intervention with a quasi-experimental design and reference area. METHODS IHHP targeted the population-at-large (n = 2,180,000) in three districts in central Iran. Data from independent sample surveys before (2000 - 2001) and after (2007) this program were used to compare differences in the intervention area and reference area over time after controlling for age, education level and income. The samples in 2000 - 2001 and 2007 included 6175 and 4719 participants in intervention area, and 6339 and 4853 in reference area, respectively. Multiple interventional activities were performed based on the four main strategies of healthy nutrition, increased physical activity, tobacco control and coping with stress. RESULTS The prevalence of abdominal obesity, hypertension, hypercholesterolemia, hypertriglyceridemia and high LDL-C decreased significantly in the intervention area versus the reference area in both sexes. However the reduction in overweight and obesity was significant only in females (P < 0.05 for all). There were no significant changes in the prevalence of diabetes mellitus. In the intervention area, the prevalence of hypercholesterolemia decreased from 23.5% to 12.5% among females without any changes in females in the reference area (p < 0.0001). In males, hypercholesterolemia decreased significantly in both intervention area (18.5% to 9.6%) and reference area (14.4% to 9.8%; p = 0.005). Mean triglyceride levels had a significant decrease in the intervention area and a non-significant decrease in the reference area (p < 0.0001). CONCLUSIONS A comprehensive healthy lifestyle program comprising preventive and promotional activities that considers both population and high risk approaches can be effective in controlling cardiometabolic risk factors in a middle-income country.

Abstract
IMPORTANCE Little is known about adoption of healthy lifestyle behaviors among individuals with a coronary heart disease (CHD) or stroke event in communities across a range of countries worldwide. OBJECTIVE To examine the prevalence of avoidance or cessation of smoking, eating a healthy diet, and undertaking regular physical activities by individuals with a CHD or stroke event. DESIGN, SETTING, AND PARTICIPANTS Prospective Urban Rural Epidemiology (PURE) was a large, prospective cohort study that used an epidemiological survey of 153,996 adults, aged 35 to 70 years, from 628 urban and rural communities in 3 high-income countries (HIC), 7 upper-middle-income countries (UMIC), 3 lower-middle-income countries (LMIC), and 4 low-income countries (LIC), who were enrolled between January 2003 and December 2009. MAIN OUTCOME MEASURES Smoking status (current, former, never), level of exercise (low, <600 metabolic equivalent task [MET]-min/wk; moderate, 600-3000 MET-min/wk; high, >3000 MET-min/wk), and diet (classified by the Food Frequency Questionnaire and defined using the Alternative Healthy Eating Index). RESULTS Among 7519 individuals with self-reported CHD (past event: median, 5.0 [interquartile range {IQR}, 2.0-10.0] years ago) or stroke (past event: median, 4.0 [IQR, 2.0-8.0] years ago), 18.5% (95% CI, 17.6%-19.4%) continued to smoke; only 35.1% (95% CI, 29.6%-41.0%) undertook high levels of work- or leisure-related physical activity, and 39.0% (95% CI, 30.0%-48.7%) had healthy diets; 14.3% (95% CI, 11.7%-17.3%) did not undertake any of the 3 healthy lifestyle behaviors and 4.3% (95% CI, 3.1%-5.8%) had all 3. Overall, 52.5% (95% CI, 50.7%-54.3%) quit smoking (by income country classification: 74.9% [95% CI, 71.1%-78.6%] in HIC; 56.5% [95% CI, 53.4%-58.6%] in UMIC; 42.6% [95% CI, 39.6%-45.6%] in LMIC; and 38.1% [95% CI, 33.1%-43.2%] in LIC). Levels of physical activity increased with increasing country income but this trend was not statistically significant. The lowest prevalence of eating healthy diets was in LIC (25.8%; 95% CI, 13.0%-44.8%) compared with LMIC (43.2%; 95% CI, 30.0%-57.4%), UMIC (45.1%, 95% CI, 30.9%-60.1%), and HIC (43.4%, 95% CI, 21.0%-68.7%). CONCLUSION AND RELEVANCE Among a sample of patients with a CHD or stroke event from countries with varying income levels, the prevalence of healthy lifestyle behaviors was low, with even lower levels in poorer countries.

Abstract
BACKGROUND/OBJECTIVE The study was carried out to assess the relationship between nut consumption and lipid profile among Iranian adults. SUBJECT/METHODS The study was based on data from the Isfahan Healthy Heart Program across three counties in central Iran in 2007. A cross-sectional survey of 9660 randomly selected adults aged ≥ 19 years were chosen based on sex, age and settlement distributions in each community. Nutritional behaviors were assessed by validated qualitative 48-item food frequency questionnaires, which covered regular intakes of four types of nuts: walnuts, almonds, pistachios and hazelnuts. Analysis of covariance and logistic regression tests were utilized to determine odds ratio (OR) 95% confidence interval of hyperlipidemia according to nut consumption patterns in unadjusted and three-adjusted models. RESULTS The results showed a significant link between high nut consumption and lower total cholesterol, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) levels and apo B/apo A ratio (P<0.05) in female subjects and lower TG, LDL-C and apoB/apoA ratio in male subjects (P<0.05). The frequency of nut consumption was inversely associated with dyslipidemia, especially for those who had consumed nuts ≥ 4 times weekly (0.67 (0.57-0.79)). After adjusting for sex, age and other potential confounders, ORs increased enormously. Except for low apo A and high LDL-C, more frequent nut consumption (4 ≤ times per week) had a significant inverse effect on other dyslipidemia risk factors in all four models. CONCLUSIONS We concluded that frequent consumption of nuts, particularly ≥ 4 times a week, may result in lower dyslipidemia occurrences and may exert cardioprotective effects.

Abstract
OBJECTIVE To assess the impact of gender and living area on cardiovascular risk factors in the context of a comprehensive lifestyle intervention program. DESIGN Data from independent sample surveys before (2000--2001) and after (2007) a community trial, entitled the Isfahan Healthy Heart Program (IHHP) were used to compare differences in the intervention area (IA) and reference area (RA) by gender and living area. SETTING The interventions targeted the population living in Isfahan and Najaf-Abad counties as IA and Arak as RA. PARTICIPANTS Overall, 12 514 individuals who were more than 19 years of age were studied at baseline, and 9570 were studied in postintervention phase. INTERVENTIONS Multiple activities were conducted in connection with each of the four main strategies of healthy nutrition, increasing physical activity, tobacco control, and coping with stress. MAIN OUTCOMES Comparing serum lipids levels, blood pressure, blood glucose and obesity indices changes between IA and RA based on sex and living areas during the study. RESULTS In IA, while the prevalence of hypertension declined in urban and rural females (P < 0.05). In IA, the prevalence of hypercholesterolemia and hypertriglyceridemia decreased in both females and males of urban and rural areas except for hypercholesterolemia in rural males (P < 0.01). In RA, the significant changes include both decrease in the hypercholesterolemia among rural males (P < 0.001) and hypertriglyceridemia in urban females (P < 0.01), while hypertriglyceridemia was significantly increased in rural females (P < 0.01). CONCLUSIONS This comprehensive community trial was effective in controlling many risk factors in both sexes in urban and rural areas. These findings also reflect the transitional status of rural population in adopting urban lifestyle behaviors.

Abstract
BACKGROUND Visfatin is a new adipocytokine which is largely secreted by visceral adipose tissue and its effects in the development of diabetes and inflammatory reactions are similar to insulin. It acts synergistically with insulin in increasing glucose cellular uptake, stimulating glucose transfer to the muscle and adipose tissue, as well as in preventing hepatic glucose production. Its insulin-like effects are mediated through direct connection and activation of insulin receptors without any change or competition with the insulin. METHODS This case-control study was conducted among 64 women consisting of 32 diabetic patients, and 32 age-matched healthy controls. The case group consisted of 32 post-menopausal diabetic women, aged 45-65 years. Those patients were eligible who had a history of at least five years of type II diabetes, without any complications of diabetes, and who were treated only by oral glucose-lowering medications. Those individuals with C-reactive protein (CRP) test of 3+ and above were excluded from the study. Results were compared with age- and sex- matched controls. RESULTS Average visfatin level was significantly higher in diabetic patients than in controls (4.3 ± 1.06ng/dl vs. 3.15 ± 0.74ng/dl, respectively< 0.001). The mean values of anthropometric indexes and lipid profile were not significantly different between diabetic patients and controls CONCLUSION This study documented an inverse relationship between circulating level of visfatin and fasting blood glucose. This finding may suggest the role of increased visfatin level and increase in synthesis and secretion of the cytokines from adipocytes. These findings may be useful for primary and secondary preventive issues in diabetic and pre-diabetic individuals.

Abstract
OBJECTIVE The main purpose of this study sought to evaluate the frequency of sensitivity of Iranian asthmatic patients to three regional Aspergillus species of fumigatus, flavus and niger, by detection of antigen-specific IgE in the patients' sera. PATIENTS AND METHODS Crude extracts were prepared following the disruption of fungi cell walls by the application of glass beads and their protein fractions were isolated by SDS-PAGE. After electrotransfer of protein bands into the nitrocellulose membrane, IgE-immunoblotting was performed against the sera from 32 asthmatic patients in addition to 20 healthy controls. RESULTS Our results interestingly showed that all of the studied Iranian asthmatic patients were sensitive to A. fumigatus and A. flavus antigens. This frequency was 65.6% in the case of A. niger, however, all control samples were negative. Age/sex analysis generally indicated higher sensitivities of young patients (<30 years old) to Aspergillus species with a statistical significance in the case of A. niger (P=0.02) and additionally more sensitivity of females. Using Immunoblotting assay, 23 IgE-reactive allergenic components from A. fumigatus, 15 from A. flavus and 13 from A. niger in a broad molecular weight spectrum were identified, among which several fragments were not previously reported. CONCLUSION Overall, this study found a high frequency of sensitivity of Iranian asthmatic patients to regional isolates of A. fumigatus, A. flavus and A. niger, which suggested the importance of these species in development of asthma. Moreover, we reported allergenic profiles of Iranian isolates in different patterns not previously observed.

Abstract
BACKGROUND This study aimed to assess the effects of a 6-year-long community-participatory program including school-based interventions on mean values and prevalence of cardiometabolic risk factors among adolescents. METHODS The interventions of this community trial, conducted from 2000 to 2007 in Iran, targeted the whole population (of nearly two millions) living in two cities considered as the intervention area (IA) in comparison with a reference area (RA). Data from surveys conducted before and after interventions was used to compare the differences between the secondary school students of the IA and RA. RESULTS The prevalence of hypercholesterolemia and hypertriglyceridemia declined significantly in girls and boys in the IA (P < 0.01). The prevalence of high LDL-C decreased significantly in the girls in the RA (P = 0.002). Among both sexes in the IA, the prevalence of low HDL-C increased significantly (P < 0.001), whereas it decreased in the girls and boys in the RA (P = 0.04). Although in the IA, the prevalence of overweight and obesity decreased significantly in girls (P = 0.001), it increased in boys (P = 0.001) as well as in the girls of the RA (P = 0.01). CONCLUSION By performing school-based interventions, our study was successful, at least in part, in controlling some cardiometabolic risk factors in adolescents. Such modifications may have long-term impacts on non-communicable diseases prevention in adulthood.

Abstract
BACKGROUND Hypertension is a condition normally detected in people with type II diabetes.It eventually leads to cardiovascular diseases in the patient. Visfatin is an adipocytokine which issecreted from adipose tissue and can affect the inflammatory reaction and also serum lipidlevels. Additionally, omega-3 inhibits the accumulation of fat and formation of insulinresistance. The current study tried to investigate the effects of omega-3 on blood pressurecompared to placebo and the relationship between serum visfatin levels and blood pressure. METHODS A total number of 71 women with type II diabetes were randomly assigned to2 groups to receive either omega-3 capsules or placebo capsules. In the first step, aquestionnaire consisting age, height, weight, waist and hip circumferences, and systolic anddiastolic blood pressure was filled out for each subject. Blood samples were then collected forlaboratory tests. The next step was to conduct 8 weeks of intervention. All variables, except age,were measured again after the intervention. Hip circumference was considered as the maximumcircumference of the buttocks. Waist circumference was measured by placing a tape horizontallyacross the abdomen at the end of a normal exhalation. Laboratory tests included the assessmentof visfatin, glucose, and glycated hemoglobin (HbA1c) concentrations. Lipid profile, i.e. lowdensity lipoprotein (LDL), high density lipoprotein (HDL), triglyceride (TG), and cholesterol,was also assessed. Using SPSS18, data obtained from the study was analyzed by a variety ofappropriate statistical tests. RESULTS There was a significant change in mean differences of systolic and diastolic bloodpressure. Blood pressure showed a significant reduction in the omega-3 group compared to theplacebo group. However, no significant changes were observed in systolic and diastolic bloodpressure before and after the intervention (P > 0.05). CONCLUSION Based on the results of this study, a daily consumption of omega-3 is suggestedfor patients with type II diabetes.

Abstract
BACKGROUND Some studies showed that smoking follows an upward trend in Asian countries as compared with other countries. The purpose of this study was to examine the effect of cigarette smoking on cardiovascular diseases and risk factors of atherosclerosis in patients with hypertension. METHODS This study was conducted on 6123 men residing in central Iran (Isfahan and Markazi Provinces) that participated in Isfahan Healthy Heart Project (IHHP). Subjects were randomly selected using cluster sampling method. All the subjects were studied in terms of their history of cardiovascular disease, demographic characteristics, smoking, blood pressure, physical examination, pulse rate, respiratory rate, weight, height, waist circumference, and blood measurements including LDL-C, HDL-C, total cholesterol, triglyceride, fasting blood sugar and 2-hour post prandial test. RESULTS While 893 subjects suffered from hypertension, 5230 subjects were healthy. The hypertension prevalence was 2.5 times more in urban areas compared to rural areas that showed a significant difference as it increased to 3.5 times smoking factor was considered. The prevalence of risk factors of atherosclerosis and also cardiovascular complications in patients with hypertension were significantly higher than healthy people. Furthermore, they were higher in smokers with hypertension and those exposed to the cigarette smoke than nonsmokers. CONCLUSION Smoking and passive smoking had an increasing effect on the prevalence of risk factors of atherosclerosis and consequently the incidence of cardiovascular diseases in patients with hypertension.

Abstract
BACKGROUND Atherosclerosis is one of the leading causes of mortality all around the world. Obesity is an independent risk factor for atherosclerosis and cardiovascular diseases (CVD). In this respect, we decided to examine the effect of the subgroups of weight on cardiovascular risk factors. METHODS This cross-sectional study was done in 2006 using the data obtained by the Iranian Healthy Heart Program (IHHP) and based on classification of obesity by the World Health Organization (WHO). In this study, the samples were tested based on the Framingham risk score, Metabolic Measuring Score (MMS) and classification of obesity. Chi-square and ANOVA were used for statistical analysis. RESULTS 12514 people with a mean age of 38 participated in this study. 6.8% of women and 14% of men had university degrees (higher than diploma). Obesity was seen in women more than men: 56.4% of women and 40% of men had a Body Mass Index of (BMI) ≥ 25 Kg/m2. 13% of the subjects had FBS > 110 and13.9% of them were using hypertensive drugs. In this study, we found that all risk factors, except HDL cholesterol in men, increased with an increase in weight. This finding is also confirmed by the Framingham flowfigure for men and women. CONCLUSION One of every two Americans, of any age and sex, has a Body Mass Index of (BMI) ≥ 25 Kg/m2. Obesity associated CVD and other serious diseases. Many studies have been done in different countries to find the relationship between obesity and CVD risk factors. For example, in the U.S.A and Canada they found that emteropiotic parameters, blood presser and lipids increased by age(of both sexes). Moreover, another study done in China, which is a country in Asia like Iran, shows that BMI has an indirect effect on HDL cholesterol, LDL cholesterol and triglyceride. This data is consistent with the results of the current study. However, In China they found that this relationship in men is stronger than women, but our study reveals the opposite.
