RESUMO

BACKGROUND AND AIMS: Long-term associations between nut consumption and cardiometabolic risk factors are not well known. We investigated the relationship between nut consumption and cardiometabolic risk factors including dyslipidemia, hypertension, diabetes mellitus (DM), and obesity in a cohort of Iranian adults. METHODS AND RESULTS: The study was conducted within the framework of the Isfahan Cohort Study on 1387 healthy participants. The participants were followed up for 12 years. A validated food frequency questionnaire was completed, and anthropometric measurements, blood pressure, and fasting serum lipids and blood sugar were evaluated in three phases. Mixed-effects binary logistic regression was applied to examine the associations between nut consumption and cardiometabolic risk factors. The participants were classified according to the tertiles of nut consumption as cut-points, and associations were evaluated between the thirds of nut intake. Subjects in the last third were less likely to have hypercholesterolemia [OR (95% CI): 0.76 (0.60-0.97)], hypertriglyceridemia [OR (95% CI): 0.74 (0.58-0.93)], and obesity [OR (95% CI): 0.79 (0.50-0.98)] but more likely to have DM [OR (95% CI): 1.85 (1.27-2.68)] than those in the first third. However, after adjustment for various potential confounders, the associations remained significant only for obesity [OR (95% CI): 0.67 (0.48-0.94)] and DM [OR (95% CI): 2.23 (1.37-3.64)]. CONCLUSION: After adjustment for potential confounders, we observed an inverse association for nut consumption and obesity but positive association for DM and nut intake. On the basis of our findings, it is suggested that incorporation of nuts into people's usual diet may have beneficial effects for individuals with lower risk such as subjects without DM.

RESUMO

Considering the main effect of obesity on chronic non-communicable diseases, this study was performed to assess the association between body mass index (BMI), waist-circumference (WC), cardio-metabolic risk factors and to corroborate whether either or both BMI and WC are independently associated with the risk factors in a sample of Iranian adults. This cross-sectional study was performed on data from baseline survey of Isfahan Healthy Heart Program (IHHP). The study was done on 12,514 randomly-selected adults in Isfahan, Najafabad and Arak counties in 2000-2001. Ages of the subjects were recorded. Fasting blood glucose (FBG), 2-hour post-load glucose (2hpp), serum lipids, systolic and diastolic blood pressure (SBP and DBP), BMI, WC, smoking status, and total daily physical activity were determined. Increase in BMI and WC had a significant positive relation with the mean of FBG, 2hpp, SBP, DBP, serum lipids, except for HDL-C (p<0.001 for all). After adjustment for age, smoking, physical activity, socioeconomic status (SES), and BMI, the highest odds ratio (OR) (95% CI) for diabetes mellitus (DM) according to WC was 3.13 (1.93-5.08) and 1.99 (1.15-3.44) in women and men respectively. Moreover, the highest ORs based on BMI with adjustment for age, smoking, physical activity, SES, and WC were for dyslipidaemia (DLP) [1.97 (1.58-2.45) in women and 2.96 (2.41-3.63) in men]. The use of BMI or WC alone in the models caused to enhance all ORs. When both BMI and WC were entered in the model, the ORs for all risk factors, in men, according to BMI, were more compared to WC. However, in women, ORs for DM and hypertension (HTN) in WC quartiles were more than in BMI quartiles. BMI is the better predictor of DM, HTN, and DLP in men compared to WC. Conversely, in women, WC is a superior predictor than BMI, particularly for DM and HTN. Furthermore, the measurement of both WC and BMI in Iranian adults may be a better predictor of traditional risk factors of CVDs compared to BMI or WC alone.

RESUMO

Association between white rice intake and risk factors of cardiovascular diseases remained uncertain. Most of the previous published studies have been done in western countries with different lifestyles, and scant data are available from the Middle East region, including Iran. This cross-sectional study was conducted in the structure of Isfahan Healthy Heart Program (IHHP) to assess the association between white rice consumption and risk factors of cardiovascular diseases. In the present study, 3,006 men were included from three counties of Isfahan, Najafabad, and Arak by multistage cluster random-sampling method. Dietary intake was assessed with a 49-item food frequency questionnaire (FFQ). Laboratory assessment was done in a standardized central laboratory. Outcome variables were fasting blood glucose, serum lipid levels, and anthropometric variables. Socioeconomic and demographic data, physical activity, and body mass index (BMI) were considered covariates and were adjusted in analysis. In this study, Student's t-test, chi-square test, and logistic regression were used for statistical analyses. Means of BMI among those subjects who consumed white rice less than 7 times per week and people who consumed 7-14 times per week were almost similar--24.8 +/- 4.3 vs 24.5 +/- 4.7 kg/m2. There was no significant association between white rice consumption and risk factors of cardiovascular diseases, such as fasting blood sugar arid serum lipid profiles. Although whole grain consumption has undeniable effect on preventing cardiovascular disease risk, white rice consumption was not associated with cardiovascular risks among Iranian men in the present study. Further prospective studies with a semi-quantitative FFQ or dietary record questionnaire, representing type and portion-size of rice intake as well as cooking methods and other foods consumed with rice that affect glycaemic index (GI) of rice, are required to support our finding and to illustrate the probable mechanism.

RESUMO

BACKGROUND: Previous studies investigated the effects of dietary glycaemic index and glycaemic load on cardiovascular risk factors. Little evidence is available regarding the association between potato intake and cardiovascular risk factors in Iran. OBJECTIVE: This cross-sectional study was conducted in the first stage of Isfahan Healthy Heart Programme. METHODS: A total of 4774 subjects were included in the present study. Dietary intake was assessed with a 49-item food frequency questionnaire. Biochemical assessments were done according to the standard protocol. RESULTS: There were significant associations between potato consumption and diabetes mellitus (odds ratio (OR): 1.38; 95% CI: 1.14-1.67; p < 0.001), high fasting blood sugar level (OR: 1.40; 95% CI: 1.17-1.68; p < 0.001) and low serum high density lipoprotein level (OR: 1.10; 95% CI: 1.01-1.20; p = 0.02) remained after adjustments for possible confounding factors. CONCLUSION: We found a positive relation between potato consumption, high fasting blood glucose level and diabetes mellitus.

RESUMO

BACKGROUND: Macronutrients' quality may impact differently on mental health and quality of life (QOL). This study aimed to investigate the potential relationship between the carbohydrate quality index (CQI), fat quality index (FQI), protein quality index (PQI), the affective mental symptoms and QOL among Iranian adults. METHODS: The LipoKAP is a cross-sectional study, conducted with 2456 adults in Iran. A validated food frequency questionnaire was used to evaluate usual dietary intakes. A validated Iranian version of the Hospital Anxiety and Depression Scale was used to assess the severity of anxiety and depression. QOL was assessed by EQ-5D. RESULT: In the fully adjusted model, participants in the highest tertile of CQI had lower QOL than those in the lowest tertile (OR = 1.35; 95 % CI: 1.06, 1.73). Individuals in the top tertile of FQI (OR = 0.71; 95 % CI: 0.55, 0.91) and PQI (OR = 0.78; 95 % CI: 0.60; 1.01) were less likely to report lower QOL than those in the bottom tertile. An inverse association was found between PQI and depressive symptoms (OR = 0.72, 95 % CI: 0.55, 0.95), but not for CQI and FQI. LIMITATIONS: The cross-sectional design of the study and the use of a memory-based dietary tool may limit the generalizability of our findings. CONCLUSION: Higher PQI was associated with lower risk of depressive symptoms and having a low-quality life. Although CQI and FQI were not related to depressive and anxiety symptoms, higher values of FQI were associated with better QOL, while CQI showed an inverse association.

RESUMO

This study investigated the gender differences in association of some behavioural and socioeconomic factors with obesity indices in a population-based sample of 12,514 Iranian adults. The mean body mass index (BMI), waist circumference (WC), and the waist-to-hip ratio (WHR) were significantly higher in women than in men. Current and passive smoking had an inverse association with BMI among males whereas current smoking, transportation by a private car, and longer duration of watching television (TV) had a positive association with BMI among females. Current and passive smoking, cycling, and Global Dietary Index (GDI) had an inverse association with WC among males. Higher consumption of fruits and vegetables, current and passive smoking, duration of daily sleep, and GDI had an inverse association with WC among females. Using a private car for transportation had a significant positive association with WHR among both males and females. Living in an urban area, being married, and having a higher education level increased the odds ratio of obesity among both the genders. Non-manual work also increased this risk among males whereas watching TV and current smoking increased this risk among females. Such gender differences should be considered for culturally-appropriate interventional strategies to be implemented at the population level for tackling obesity and associated cardiometabolic risk factors.

RESUMO

This study aimed to assess the effects of a 2-month lifestyle modification trial on cardio-metabolic abnormalities and C-reactive protein (CRP) among obese adolescents with metabolic syndrome [phenotypically obese metabolically abnormal (POMA)] and obese adolescents without a cardio-metabolic disorder [phenotypically obese metabolically normal (POMN)], as well as in normal-weight adolescents with at least one cardio-metabolic disorder [phenotypically normal metabolically obese (PNMO)]. The study comprised 360 adolescents assigned in three groups of equal number of POMN, POMA and PNMO. They were enrolled in a trial consisting of aerobic activity classes, diet and behaviour modification, and were recalled after 6 months. Overall, 94.7% of participants completed the 2-month trial, and 87.3% of them returned after 6 months. The mean CRP was not significantly different between the POMA and PNMO groups, but was higher than in the POMN group. After the trial, body mass index (BMI) and waist circumference (WC) decreased in obese participants, and the mean body fat mass decreased in all groups. At 2 months, the mean total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG) and CRP decreased in the POMA and PNMO groups. After 2 and 6 months, the decrease in mean TC, LDL-C, TG, CRP and systolic blood pressure was greater in the POMA than in the POMN group. The magnitude of decrease in CRP correlated with that of BMI, WC, fat mass, TG, TC and LDL-C. Lifestyle modification programmes for primordial/primary prevention of chronic diseases would be beneficial at the population level and should not be limited to obese children.

RESUMO

Background and Aim: There are few pieces of evidence on the association between nut consumption and the risk of cardiovascular disease (CVD) in the Eastern Mediterranean Region. This study investigated the relationship of nut consumption with the risk of CVD and all-cause mortality in the Iranian population. Methods and Results: This population-based prospective cohort study was carried out in 6,504 randomly selected participants aged ≥35 years in central Iran (2001-2013) in the framework of the Isfahan Cohort Study. Dietary data were collected by a validated 48-item food frequency questionnaire. Subjects or their next of kin were interviewed biannually, looking for the possible occurrence of cardiovascular events and all-cause mortality. During the median follow-up of 135 months and 52,704.3 person-years, we found a total of 751 CVD events. In unadjusted model, participants in the highest quartile of nut intake had a lower CVD risk {hazard ratio (HR) [95% confidence interval (CI)]: 0.57(0.47-0.70); P for trend < 0.001}, CVD mortality [HR (95% CI): 0.54 (0.33-0.72); P for trend < 0.001], and all-cause mortality [HR (95% CI): 0.24 (0.14-0.42); P for trend < 0.001]. In the fully adjusted model, the association was diluted, and no significant relationship was found between nut intake and CVD events and all-cause mortality, except for CVD mortality in the highest quartile vs. the lowest one [HR (95% CI): 0.55 (0.30-0.98)]. Conclusion: Nut intake had an inverse association with the risk of CVD mortality. It is suggested to perform studies to examine the association of individual types of nuts and different preparation methods on CVD risk and mortality.

RESUMO

BACKGROUND: There is evidence regarding the relationship between dietary proteins intake and blood pressure (BP), but they had inconsistent results. Therefore, this study was designed to assess the association between different kinds of protein intake (animal and plant protein) and BP. MATERIALS AND METHODS: Data were collected from Isfahan Healthy Heart Program. We performed a cross-sectional study among 9660 randomly selected Iranian adults aged ≥19-year-old that they were selected from three large Iranian regions in 2007. A simplified validated 48-item-food frequency questionnaire was used to assess dietary intake including all kinds of protein. Systolic and diastolic BPs were measured in duplicate by trained personnel using a standard protocol. Multivariable regressions were applied to assess the relationship between protein intake and BP levels and the presence of hypertension (HTN). RESULTS: More frequent consumption of animal, plant, and total protein intake were inversely associated with BP in a crude model (P < 0.001); however, after adjustment for potential confounders this relationship remained only for plant protein (P = 0.04). The risk of HTN occurrence decreased in the highest quintile of total and plant protein consumption by 19% (odds ratio [OR] = 0.81; confidence interval [CI]: [0.65-0.96]; P for trend = 0.004) and 18% (OR = 0.82; [CI: (0.67-0.94]; P for trend = 0.03), respectively. CONCLUSIONS: More frequent protein intake, especially plant protein consumption was inversely associated with BP and risk of HTN among Iranian adults.

RESUMO

AIM: There is controversy around the clinical effects of the dietary glycaemic index (GI) and glycaemic load (GL) on cardiovascular diseases risk factors such as metabolic syndrome (MetS). So, the present study was performed to evaluate the relationship between GI or GL and metabolic syndrome in an Iranian adult population in 2007. METHODS: The study was based on data from a sub-sample of the Isfahan Healthy Heart Program (IHHP), collected across three cities in central Iran, in the year 2007. This was a cross-sectional survey of 1618 randomly selected adults aged ≥19 years. Nutritional assessment was conducted by a single 24-hour recall questionnaire. Fasting serum lipids, anthropometric indicators and blood pressure were measured by standard methods. Analysis of covariance was used to compare metabolic syndrome components according to energy-adjusted GI and GL levels. To expose the effect of potential confounders, hierarchical logistic regression models were utilised to determine adjusted odds ratios (OR) and 95% CI. RESULTS: After adjustment for age, gender, body mass index and energy intake, high GI was found to be significantly associated with MetS (OR 95% CI) (1.46 (1.01-2.12)). This was attenuated marginally by excluding the confounding effects of dietary fibre intake (1.29 (1.01-1.74)). All hierarchical models illustrated no significant association between energy-adjusted GL and the risk of MetS adjusted for confounders. CONCLUSIONS: There is a positive relationship between dietary GI, but not GL, and the presence of MetS after adjustment for potential confounders. However, studies with long duration of follow up and experimental studies are still required to confirm this relationship.

RESUMO

BACKGROUND: Dietary diversity score (DDS) measurement was used to assessment of diet quality in different disease like cardiovascular disease. One way to improve the cardiovascular patient's ability is cardiac rehabilitation program that include exercise training, nutrition consultation and psychological treatment. No study was designed to compare the DDS before and after dietary consultation among cardiac rehabilitation patients, so this study was designed to examine this purpose. METHODS: Subjects were participated in the 2-month cardiac rehabilitation program. All patients that completed the cardiac rehabilitation program and 2 dietary records (before and after nutritional counseling in cardiac rehabilitation program) enrolled in study. Kant et al method was used for scoring dietary diversity. Data were analyzed using the statistical package for social sciences (SPSS version 20). Wilcoxon test were used to compare DDS score for each subgroup and pair sample T test was used to compare total DDS after and before nutrition counseling. P < 0.05 was considered as statistically significant. RESULTS: The differences between DDS of grain, fruit, vegetable and meat before and after nutrition counseling were not significant (P = 0.635, P = 0.423, P = 0.826, P = 0.207 respectively), but differences of DDS for dairy and total DDS before and after nutrition counseling were significant (P = 0, P = 0.001). CONCLUSIONS: Dietary diversity was increased after nutrition counseling among patients with cardiac disease.

RESUMO

BACKGROUND: Dietary assessment is the first step of dietary modification in community-based interventional programs. This study was performed to validate a simple food frequency questionnaire (SFFQ) for assessment of selected food items in epidemiological studies with a large sample size as well as community trails. METHODS: This validation study was carried out on 264 healthy adults aged ≥ 41 years old living in 3 district central of Iran, including Isfahan, Najafabad, and Arak. Selected food intakes were assessed using a 48-item food frequency questionnaire (FFQ). The FFQ was interviewer-administered, which was completed twice; at the beginning of the study and 2 weeks thereafter. The validity of this SFFQ was examined compared to estimated amount by single 24 h dietary recall and 2 days dietary record. Validation of the FFQ was determined using Spearman correlation coefficients between daily frequency consumption of food groups as assessed by the FFQ and the qualitative amount of daily food groups intake accessed by dietary reference method was applied to evaluate validity. Intraclass correlation coefficients (ICC) were used to determine the reproducibility. RESULTS: Spearman correlation coefficient between the estimated amount of food groups intake by examined and reference methods ranged from 0.105 (P = 0.378) in pickles to 0.48 (P < 0.001) in plant protein. ICC for reproducibility of FFQ were between 0.47-0.69 in different food groups (P < 0.001). CONCLUSION: The designed SFFQ has a good relative validity and reproducibility for assessment of selected food groups intake. Thus, it can serve as a valid tool in epidemiological studies and clinical trial with large participants.

RESUMO

BACKGROUND: Epidemiologic studies have shown an inverse association between dietary fiber and metabolic syndrome (MetS). Therefore, the purpose of this study was to investigate the association between MetS and consumption of legumes in adults in Isfahan, Iran. METHODS: This cross-sectional study was carried out on 2027 individuals who were a subsample of the 3rd phase of the Isfahan Healthy Heart Program (IHHP). Basic characteristics information such as age, sex, smoking status, and physical activity were collected using a questionnaire. A validated 48-item food frequency questionnaire was used to assess dietary behaviors. Blood pressure, waist circumference (WC), glucose, triacylglycerols, and high-density lipoprotein cholesterol were measured, and MetS was defined based on Adult Treatment Panel III guidelines. Multiple logistic regression models examined associations of frequency consumption of legumes with MetS occurrence and its components. RESULTS: All MetS components were less prevalent among subjects with regular legume intake (P < 0.01). Legume intake was inversely associated with the risk of MetS, after adjustment for confounding factors in women. Life style adjusted odds ratio of Mets between highest and lowest tertile and no consumption (as reference category) of legume intake were 0.31 (0.13, 0.70), 0.38 (0.17, 0.87), respectively, in women (P = 0.01). CONCLUSION: This study showed that age has a crucial role in MetS incidence; therefore, after further age adjustment to lifestyle adjusted model there was no significant difference in lower and higher tertile of legume intake and MetS.

RESUMO

BACKGROUND/OBJECTIVE: It is expected that dairy products such as cheeses, which are the main source of cholesterol and saturated fat, may lead to the development or increase the risk of cardiovascular and metabolic diseases; however, the results of different studies are inconsistent. This study was conducted to assess the association between cheese consumption and cardiovascular risk factors in an Iranian adult population. SUBJECTS/METHODS: Information from the Isfahan Healthy Heart Program (IHHP) was used for this cross-sectional study with a total of 1,752 participants (782 men and 970 women). Weight, height, waist and hip circumference measurement, as well as fasting blood samples were gathered and biochemical assessments were done. To evaluate the dietary intakes of participants a validated food frequency questionnaire, consists of 49 items, was completed by expert technicians. Consumption of cheese was classified as less than 7 times per week and 7-14 times per week. RESULTS: Higher consumption of cheese was associated with higher C-Reactive Protein (CRP), apolipoprotein A and high density lipoprotein cholesterol (HDL-C) level but not with fasting blood sugar (FBS), total cholesterol, low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and apolipoprotein B. Higher consumption of cheese was positively associated with consumption of liquid and solid oil, grain, pulses, fruit, vegetable, meat and dairy, and negatively associated with Global Dietary Index. After control for other potential confounders the association between cheese intake and metabolic syndrome (OR: 0.81; 96%CI: 0.71-0.94), low HDL-C level (OR: 0.87; 96%CI: 0.79-0.96) and dyslipidemia (OR: 0.88; 96%CI: 0.79-0.98) became negatively significant. CONCLUSION: This study found an inverse association between the frequency of cheese intake and cardiovascular risk factors; however, further prospective studies are required to confirm the present results and to illustrate its mechanisms.

RESUMO

BACKGROUND: Stress has been considered as a highly common disorder that has a complicated relation with dietary intake and has been linked with both increased and decreased dietary intake. OBJECTIVE: This study was conducted to assess the association between food consumption and stress levels in an Iranian adult population. METHODS: In this cross-sectional study, data from the third phase of Isfahan Healthy Heart Program (IHHP) that was conducted for cardiovascular diseases prevention and health promotion were used. Nine thousand five hundred forty-nine adults aged ≥ 18 years participated in the study. Dietary habits were assessed by a 49- item Food Frequency Questionnaire (FFQ). Stress levels were assessed by General Health Questionnaire-12 (GHQ-12). The participants were separated on the basis of their stress levels into two groups as the low- and high- stress groups.  RESULTS: Individuals in the low- stress group were significantly younger and tended to have higher physical activity and education level, lower LDL cholesterol, and were less likely to be current smokers. Dietary intake of unsaturated oils, grains, fruits, vegetables, meat, and dairy products was significantly higher in the low- stress group whereas dietary intake of saturated oils was significantly lower; moreover, Global Dietary Index (GDI) was lower in the low- stress group. We found a significant positive association between stress level, GDI (OR: 1.24; 95% CI: 1.14 - 1.35), and saturated oils (OR: 1.17; 95% CI: 1.08 - 1.28) and inverse association between stress level and intake of unsaturated oils (OR: 0.84 ; 95% CI: 0.77 - 0.91), fruits and vegetables (OR: 0.83; 95% CI: 0.76 - 0.90), meat (OR: 0.88; 95%CI: 0.82 - 0.97),and dairy products (OR: 0.88 ; 95% CI: 0.81 - 0.96) after adjustments based on sex, age, smoking, and physical activity. CONCLUSION: Our results showed a significant positive association between dietary intake and stress. We must have a special attention to dietary intake in stress management program of high- stress individuals, and in dietary recommendations, psychologic aspects should be considered. However, prospective longitudinal studies are needed to assess the causal relationship between stress and dietary factors.

RESUMO

BACKGROUND: Few data are available linking intake of sugar-sweetened beverages (SSBs) with the metabolic syndrome. Furthermore, findings from these studies are inconsistent and most are from Western societies; no information is available in this regard from Middle Eastern populations. OBJECTIVE: This study was conducted to assess the relationship between SSB consumption and metabolic syndrome in an Iranian adult population. METHODS: In this cross-sectional study, data from 1,752 people (782 men and 970 women) that were selected with the multistage cluster random sampling method from three counties of Isfahan, Najafabad and Arak were used. A validated food frequency questionnaire was used to assess participants' usual dietary intakes. Consumption of SSBs was calculated by summing up the consumption of 'soft drinks' and 'artificially sweetened fruit juices'. To categorize participants, we used three levels of SSB consumption: <1 time/week, 1-3 times/week, and >3 times/week. Biochemical assessments were done after an overnight fasting. Metabolic syndrome was defined according to the guidelines of Adult Treatment Panel III. RESULTS: Subjects with high consumption of SSBs (>3 times/week) were younger than those with low consumption (<1 time/week). Mean BMI was not significantly different across SSB categories. High consumption of SSBs was associated with greater intakes of energy and almost all food groups. We found a significant difference in serum triglyceride levels between men consuming SSBs 1-3 times/week and those consuming <1 time/week. However, after controlling for potential confounders, this association disappeared. In crude models, no significant associations were found between SSB intake and prevalence of the metabolic syndrome in either gender. After adjustment for potential confounders including BMI, we found that men in the top category of SSB intake were 17% more likely to have the metabolic syndrome (odds ratio (OR) 1.17; 95% confidence interval (95% CI) 0.56-2.46), while women in the highest category were 20% less likely to have the syndrome (OR 0.80; 95% CI 0.46-1.42) as compared with those in the bottom category. However, these associations were not significant in either men or women. CONCLUSION: Our results do not support the previous findings on the association between SSB consumption and metabolic syndrome. Prospective studies are needed to further explore for this association.
