AbstractObjectiveTo compare the ability of waist circumference (WC), body mass index (BMI), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) to predict cardiovascular risk factors in an urban adult population of Tehranian women.DesignPopulation-based cross-sectional study.SettingTehran, the capital of Iran.SubjectsThis study was conducted on 5073 women aged 18–74 years, participants of the Tehran Lipid and Glucose Study. Demographic data were collected. Anthropometric indices were measured according to standard protocols. Cut-off points of BMI, WC, WHR and WHtR were considered as 25 kg m−2, 80 cm, 0.8 and 0.5, respectively. Blood pressure was measured and hypertension was defined based on the sixth report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure. Biochemical analyses were conducted on fasting blood samples. Diabetes was defined as fasting plasma glucose ≥126 mg dl−1or 2-hour plasma glucose ≥200 mg dl−1and dyslipidaemia based on the third report of the National Cholesterol Education Program Expert Panel. The presence of ‘at least one risk factor’ from the three major cardiovascular risk factors (hypertension, dyslipidaemia and diabetes) was also evaluated.ResultsMean (±standard deviation) age of women was 39.9 ± 14.6 years; mean BMI, WC, WHR and WHtR were 27.1 ± 1.5 kg m−2, 86.5 ± 13.5 cm and 0.83 ± 0.08 and 0.55 ± 0.08, respectively. Of the four anthropometric measures, WC had the highest sensitivity and specificity to identify subjects with risk factors in both the 18–39 year and the 40–74 year age categories. WC was seen to have a higher percentage of correct prediction than BMI, WHR and WHtR.ConclusionIt is concluded that WC is the best screening measure for cardiovascular risk factors, compared with BMI, WHR and WHtR, in Tehranian adult women.

Detrimental effects oftrans-fats on lipid profiles, blood pressure and plasma glucose levels have been documented by short-term clinical trials with high doses oftrans-fats, but limited observational studies have considered habitual consumption of partially hydrogenated vegetable oil (PHVO) and these outcome variables, particularly hypertension. We aimed to evaluate the association of PHVO and non-hydrogenated vegetable oils (non-HVO) intake with individual cardiovascular risk factors. In a cross-sectional study of 486 Iranian adult women, usual dietary intakes were assessed, and fasting plasma glucose (FPG), lipid profiles and blood pressure were measured. PHVO (commonly used for cooking in Iran) were considered as the PHVO category. Sunflower oil, maize oil, rapeseed oil, soyabean oil and olive oil were defined as the non-HVO category. Diabetes (FPG ≥ 1260 mg/l), dyslipidaemia (based on Adult Treatment Panel III) and hypertension (based on Joint National Committee VI) were defined. The presence of ‘at least one risk factor’ and ‘at least two risk factors’ of the three major risk factors for CVD (hypertension, dyslipidaemia and diabetes) was also evaluated. After controlling for age and other potential confounders, a high consumption of HVO was associated with a greater risk of having dyslipidaemia (OR for topv. bottom quintile 5·04; 95 % CI 2·70, 9·36), hypertension (OR for topv. bottom quintile 3·03; 95 % CI 1·55, 6·10), at least one (OR for topv. bottom quintile 8·52; 95 % CI 4·41, 16·41) and at least two risk factors (OR for topv. bottom quintile 3·60; 95 % CI 1·64, 7·74), while those in the top quintile of non-HVO consumption had lower odds for all these conditions. Further adjustment for dietary intakes had little impact on these associations. Even after additional adjustment for BMI, the positive association of HVO and the inverse association of non-HVO with the above-mentioned cardiovascular risk factors remained significant, except for the association between non-HVO and hypertension that became marginally significant. No overall significant associations were found between the consumption of HVO and non-HVO and diabetes. Higher intakes of PHVO were associated with a greater risk of individual cardiovascular risk factors, while those of non-HVO were associated with a reduced risk.

This study was conducted to evaluate the waist circumference (WC) cut-off points to predict cardiovascular risk factors in the overweight Tehranian population. Anthropometric measures, blood pressure, and biochemical analyses were evaluated for the 15,005 participants of the Tehran Lipid and Glucose Study. Three thousand sixty-five subjects aged 18–74 years with a body mass index of 25–29.9 were enrolled in this study. Abdominal obesity was defined as WC ≥ 102 cm for men and ≥ 88 cm for women. Sensitivity of WC ≥ 102 cm to detect various cardiovascular risk factors for men aged 35–54 years was between 5% and 14%, and for men aged 55–74 years, was between 12% and 19%. The specificity of this cut-off point was between 93% and 98% and between 86% and 96% for corresponding age-categories, respectively. WC ≥ 88 cm had a sensitivity of between 28% and 41% for identifying cardiovascular risk factors in women aged 18–34 years. Sensitivity tended to increase with age and specificity tended to decrease with age in both genders. These cut-off points had the highest positive predictive value for the more prevalent risk factors in both genders. The negative predictive values were different for various risk factors among age groups. The classic cut-off points of WC failed to provide adequate evidence for the use of WC in detecting cardiovascular risk factors. Further studies should be conducted to determine optimal WC cut-off points for Iranians.

The Relationship

SummaryThe relationship between haematocrit and cardiovascular risk factors, particularly blood pressure and blood lipids, has been examined in detail in a large prospective study of 7735 middle-aged men drawn from general practices in 24 British towns. The analyses are restricted to the 5494 men free of any evidence of ischaemic heart disease at screening.Smoking, body mass index, physical activity, alcohol intake and lung function (FEV1) were factors strongly associated with haematocrit levels independent of each other. Age showed a significant but small independent association with haematocrit. Non-manual workers had slightly higher haematocrit levels than manual workers; this difference increased considerably and became significant after adjustment for the other risk factors. Diabetics showed significantly lower levels of haematocrit than non-diabetics. In the univariate analysis, haematocrit was significantly associated with total serum protein (r = 0*18), cholesterol (r = 0.16), triglyceride (r = 0.15), diastolic blood pressure (r = 0.17) and heart rate (r = 0.14); all at p <0.0001. A weaker but significant association was seen with systolic blood pressure (r = 0.09, p <0.001). These relationships remained significant even after adjustment for age, smoking, body mass index, physical activity, alcohol intake, lung function, presence of diabetes, social class and for each of the other biological variables; the relationship with systolic blood pressure was considerably weakened. No association was seen with blood glucose and HDL-cholesterol. This study has shown significant associations between several lifestyle characteristics and the haematocrit and supports the findings of a significant relationship between the haematocrit and blood lipids and blood pressure. It emphasises the role of the haematocrit in assessing the risk of ischaemic heart disease and stroke in individuals, and the need to take haematocrit levels into account in determining the importance of other cardiovascular risk factors.

Aim: The aim of this study was to investigate the effect of dietary education on cardiovascular risk factors in patients with rheumatoid arthritis. Method: In this randomized clinical trial, 112 patients with rheumatoid arthritis were randomly assigned into two groups, intervention and control. Dietary education was provided for the intervention group in 4 sessions; anthropometric measurements, serum levels of RF, triglycerides, cholesterol, HDL, LDL, and fasting blood sugar were measured before and three months after intervention. Data was analyzed using SPSS software and appropriate statistical tests. Results: The mean of total cholesterol (p <0.001), triglycerides (p = 0.004), LDL (p <0.001), systolic blood pressure (p = 0.001), diastolic blood pressure (p = 0.003), FBS and BMI (p <0.001) were decreased significantly in the intervention group after education compared the control group. Conclusion: Traditional care for rheumatoid arthritis patients is not enough. Patients need more education in order to improve their situation.

Background Cardiovascular diseases remain the leading cause of death worldwide. Atherosclerotic process increases rapidly during adolescence. Physical activity is considered important in this period to modify cardiovascular risk factors, thus preventing disease in the future.Objective To determine whether different physical activity status in adolescence can influence body mass index (BMBMI), waist-to-hip ratio, blood pressure (BP), and blood lipid profile.Methods This was a cross-sectional descriptive study, conducted from December 2009 to January 2010. Adolescents who fulfilled the study criteria were classified into high and low physical activity category. Further examination including body mass index, waist-to-hip ratio, blood pressure, and blood lipid profile were performed.Results Adolescents with high physical activity had higher, but statistically insignificant, BMBMI compared to adolescents in the P=0.493] and significantly lower waist-to-hip ratio [0.80 (range 0.73-0.9) vs.. 0.82 (range 0.7-0.9), P=0.019]. Difference in BP was not statistically significant between both groups [diastolic BP (70 (range 60-90) mmHg vs. 70 (range 60-90) mmHg, P=0.148; systolic BP 100 (range 90-130) mmHg vs. 100 (range 90-140) mmHg, P=0.228)]. Blood lipid examination in the high activity group showed significantly higher HDL cholesterol and lower triglyceride compared to the low activity group [HDL 59.8 (SD 11.8) mg/dL vs. 54.7 (SD 8.9) mg/dL; p=0.044; triglyceride: 60 (range 32-203) mmHg vs. 82 (range 37-198) mmHg, P=0.014]. Total and LDL cholesterol [total cholesterol 169.8 (SD 28.6) mmHg vs. 181.2 (SD 30.8) mmHg, P=0.107; LDL 103.6 (SD 26.8) mmHg vs. 114.1 (SD 27.3) mmHg, P=0.100] were lower in the high activity group but not statistically different in both groups.Conclusions Adolescents with high physical activity show less cardiovascular risk factors compared to those in the low physical activity group.

Abstract Background Sex differences in major cardiovascular risk factors for incident (fatal or non-fatal) all-cause dementia were assessed in the UK Biobank. The effects of these risk factors on all-cause dementia were explored by age and socioeconomic status (SES). Methods Cox proportional hazards models were used to estimate hazard ratios (HRs) and women-to-men ratio of HRs (RHR) with 95% confidence intervals (CIs) for systolic blood pressure (SBP) and diastolic blood pressure (DBP), smoking, diabetes, adiposity, stroke, SES and lipids with dementia. Poisson regression was used to estimate the sex-specific incidence rate of dementia for these risk factors. Results 502,226 individuals in midlife (54.4% women, mean age 56.5 years) with no prevalent dementia were included in the analyses. Over 11.8 years (median), 4068 participants (45.9% women) developed dementia. The crude incidence rates were 5.88 [95% CI 5.62–6.16] for women and 8.42 [8.07–8.78] for men, per 10,000 person-years. Sex was associated with the risk of dementia, where the risk was lower in women than men (HR = 0.83 [0.77–0.89]). Current smoking, diabetes, high adiposity, prior stroke and low SES were associated with a greater risk of dementia, similarly in women and men. The relationship between blood pressure (BP) and dementia was U-shaped in men but had a dose-response relationship in women: the HR for SBP per 20 mmHg was 1.08 [1.02–1.13] in women and 0.98 [0.93–1.03] in men. This sex difference was not affected by the use of antihypertensive medication at baseline. The sex difference in the effect of raised BP was consistent for dementia subtypes (vascular dementia and Alzheimer’s disease). Conclusions Several mid-life cardiovascular risk factors were associated with dementia similarly in women and men, but not raised BP. Future bespoke BP-lowering trials are necessary to understand its role in restricting cognitive decline and to clarify any sex difference.

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): The Norwegian health department Background The evidence of the long-term effects of multiple lifestyle intervention on cardiovascular risk is uncertain. We aimed to summarize the evidence from randomized clinical trials examining the efficacy of lifestyle intervention on major cardiovascular risk factors in subjects at high cardiovascular risk. Methods  Eligible trials investigated the impact of lifestyle intervention versus usual care with minimum 24 months follow-up, reporting more than one major cardiovascular risk factor. A literature search updated April 15, 2020 identified 12 eligible studies. The results from individual trials were combined using fixed and random effect models, using the standardized mean difference (SMD) to estimate effect sizes. Small-study effect was evaluated, and heterogeneity between studies examined by subgroup and meta-regression analyses considering patient- and study-level variables. Results  Small-study effect was not identified. Lifestyle intervention reduced systolic blood pressure modestly with an estimated SMD of -0.13, 95% confidence interval (CI): -0.21 to -0.04, with moderate heterogeneity (I² = 59%), corresponding to a mean difference of approximately 2 mmHg (MD = -1.86, 95% CI: -3.14 to -0.57, p = 0.0046). This effect disappeared in the subgroup of trials judged at low risk of bias (SMD = 0.02, 95% CI: -0.08 to 0.11). For the outcome total cholesterol SMD was -0.06, 95% CI: -0.13 to 0.00, with no heterogeneity (I² = 0%), indicating no effect of the intervention. Conclusion  Lifestyle intervention resulted in only a modest effect on systolic blood pressure and no effect on total cholesterol after 24 months. Further lifestyle trials should consider the challenge of maintaining larger long-term benefits to ensure impact on cardiovascular outcomes.

Abstract Objectives The objective of this study is to investigate the cardiovascular risk factors associated with metabolic syndrome (MetS), which is increasingly becoming prevalent in childhood obesity. Methods A total of 113 patients, 76 of whom were between the ages of 10 and 17 (mean age: 14.5 ± 1.8 years) and diagnosed with obesity (30 non-MetS and 46 MetS using IDF) and 37 of whom constituted the control group, participated in the study. Echocardiographic examination and atherogenicity parameters (Atherogenic index of plasma [AIP: logTG/HDL], total cholesterol/HDL, and TG/HDL ratio and non-HDL) were evaluated. Results The most common component accompanying obese MetS was found to be hypertension and low HDL. While obesity duration, body mass index (BMI), blood pressure, fasting insulin, insulin resistance, atherogenicity parameters were determined to be significantly higher in the obese-MetS group. Echocardiography showed that while the thickness, volume, and diameter of LV end-diastolic wall, left ventricular mass (LVM), LVM index (LVMI g/m2) and relative wall thickness (RWT) were significantly high in the MetS group, however, mitral E/A ratio was significantly lower (p<0.05). Change in LV geometry consistent with concentric remodeling (increased RWT, normal LVMI) was visible in obese groups. LVM were positively significantly related to BMI, waist circumference, insulin resistance, blood pressure, LDL level, and negative to mitral E/A ratio. In the obese-MetS group, LVMI was positively correlated to office systolic BP, left atrium end-diastolic volume/index. Conclusions LVMI and atherogenicity parameters that were found to be significantly higher in obese MetS exhibit increased cardiovascular risk in childhood.

Abstract Introduction Abdominal aortic diameter has shown to be a marker of adverse cardiovascular outcomes. Among the non-aneurysmal populations, studies regarding abdominal aortic diameter normal reference values are sparse. Moreover, data regarding the associations between cardiovascular risk factors and aortic diameter among men and women are limited. Purpose To establish age- and sex-specific distribution of the infra-renal abdominal aortic diameters among non-aneurysmal older adults from the general population and to investigate the associations between cardiovascular risk factors and aortic diameters in men and women. Methods From a population-based cohort, 4032 participants (mean age, 67.2 years; 60.4% women) with infra-renal diameter assessment and without history of cardiovascular disease were included. Mean and quantile values of diameters were calculated in different age groups. Multiple linear regression analysis was used to detect the association of cardiovascular risk factors with diameters in men and women. Results The mean crude diameter was larger in men [mean (SD): 19.5 (2.6) mm] compared to women [17.0 (2.4)mm] but after adjustment for body surface area (BSA), the differences were small. There was a non-linear relationship between age and diameter (p&lt;0.001). After 66 years of age, the increase in diameter with increasing age was attenuated. After age 74 years in women and 71 years in men, the relationship between age and infra-renal aortic diameter was no longer statistically significant (Figure). Waist [standardized β (95% CI): 0.02 (0.0–0.04) in women and 0.03 (0.01–0.06) in men] and diastolic blood pressure [0.04 (0.02–0.05) in women and 0.02 (0.0–0.04) in men] were the risk factors for diameters in both sexes. Body mass index [0.02 (0.01–0.09)], systolic blood pressure [−0.01 (−0.02 to −0.01)], smoking status [0.21 (0.02–0.39)], cholesterol [−0.19 (−0.29 to −0.09)], and lipid-lowering medication [−0.47 (−0.71 to −0.23)] were significantly associated with aortic diameter only in women. Conclusion The differences in the crude abdominal aortic diameter between women and men diminished after taking into account the BSA. The abdominal aortic diameter increased steeply with advancing age and up to 66 years of age. However, after 74 years in women and 71 years in men, the diameter values reached a plateau. We also observed sex differences in the associations of cardiovascular risk factors with abdominal aortic diameter. Funding Acknowledgement Type of funding source: Public Institution(s).
