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.

Background It is predicted that the prevalence of overweight and obesity will rise significantly by 2015 in young population. Problem of overweight and obesity has been recognized as public health problem worldwide due to the fact that it increases the risk of chronic diseases such as Cardiovascular Diseases (CVD), stroke, diabetes, sleep apnoea, osteoarthritis etc.Objective To assess the body mass index in medical students and its association with various cardiovascular risk factors like blood pressure, dietary habits, and family history of cardiovascular diseases.Method A university based cross-sectional analytical study was conducted in Department of Physiology, Smt. B.K. Shah Medical Institute & Research Center, Vadodara, Gujarat. Data was collected through convenient sampling technique by using self-administered questionnaire followed by anthropometric measurement. Body Mass Index (BMI) of 138 first year medical students was assessed. Systolic blood pressure, diastolic blood pressure, pulse pressure, mean blood pressure, pulse rate and arterial oxygen saturation were measured.Result Data was compiled in excel sheet, analyzed for percentage and proportion. Chi square and Pearson correlation test were also applied and alpha error was set at 5% level. In comparison to the students with normal BMI, students with BMI >25 kg/m2 (N=49) showed significantly high blood pressure indices. Dietary habits and family history of cardiovascular diseases were also noted. Highly significant association of high BMI was found with elevated blood pressure (X2=7.4042***, p<0.001) and presence of family history of cardiovascular diseases X2=9.8625***, p<0.001). BMI is negatively correlated with SpO2 (r= -0.0504, p<0.05) and pulse rate, while positively correlated with systolic blood pressure (r=0.2736) and diastolic blood pressure (r=0.0275).Conclusion In conclusion, majority (more than 35%) of medical students were overweight, high prevalence of cardiovascular risk factors like family history, elevated blood pressure and less SpO2.

Objectives The relationship between venous thrombosis (VT) and atherosclerosis is controversial in recent studies. Aortic elastic properties have a predictive value in detecting early stages of atherosclerosis. The aim of this study is to evaluate the relationship between aortic elastic properties and VT. Methods Elastic properties of aorta in patients with spontaneous VT, without history of known cardiovascular disease and cardiovascular risk factors ( n: 31), and in healthy subjects without cardiovascular risk factors ( n: 30) were compared. Elastic properties of the aorta were assessed with transthoracic echocardiography. Results A significant increase in aortic stiffness index (6.5 ± 1.0 versus 6 ± 0.7, P = 0.03) and a significant decrease in aortic strain and aortic distensibility were found in patients with VT compared with healthy subjects (8.4 ± 7 versus 13 ± 8, P = 0.01, 4.9 ± 4.8 versus 6.5 ± 4.4, P = 0.03, respectively). Conclusions Elastic properties of aorta in patients with spontaneous VT were impaired. These results may support the role of endothelial dysfunction in the pathogenesis of VT.

Purpose:The objective of this study was to characterize the relationship between objectively-measured physical activity (PA) and cardiovascular risk factors in 7-year-old children and test the hypothesis that it differs by race.Methods:Cross-sectional study of 308 7-year-old children drawn from a major US metropolitan community. PA (moderate-to-vigorous, MVPA; light, LPA; and inactivity, IA) was measured by accelerometry (RT3). Cardiovascular risk factors included BMI, blood pressure, and serum lipids, glucose and insulin concentrations. General linear modeling was used to evaluate the independent associations between PA measures and cardiovascular risk factors and interactions by race.Results:In black children, greater time spent in PA was independently associated with lower levels of triglycerides (MVPA and LPA, both p < .01), glucose (MVPA, p < .05), and insulin (MVPA, p < .01); these associations were not evident in white children. Across races, greater inactivity was independently associated with greater low-density lipoprotein cholesterol in overweight participants (p < .01) but not in normal weight participants. No PA measure was associated with BMI, systolic blood pressure, or high-density lipoprotein cholesterol.Conclusions:In this cohort of 7-year-old children, the relationship between PA and some cardiovascular risk factors differed by race. These findings may have implications for targeting of PA promotion efforts in children.

AbstractA history of preterm or small (SGA) or large (LGA) for gestational age offspring is associated with smoking and unfavorable levels of BMI, blood pressure, glucose and lipids. Whether and to what extent the excess cardiovascular risk observed in women with these pregnancy complications is explained by conventional cardiovascular risk factors (CVRFs) is not known. We examined the association between a history of SGA, LGA or preterm birth and cardiovascular disease among 23,284 parous women and quantified the contribution of individual CVRFs to the excess cardiovascular risk using an inverse odds weighting approach. The hazard ratios (HR) between SGA and LGA offspring and CVD were 1.30 (95% confidence interval (CI) 1.15, 1.48) and 0.89 (95% CI 0.76, 1.03), respectively. Smoking explained 49% and blood pressure may have explained ≈12% of the excess cardiovascular risk in women with SGA offspring. Women with preterm birth had a 24% increased risk of CVD (HR 1.24, 95% CI 1.06, 1.45), but we found no evidence for CVRFs explaining any of this excess cardiovascular risk. While smoking explains a substantial proportion of excess cardiovascular risk in women with SGA offspring and blood pressure may explain a small proportion in these women, we found no evidence that conventional CVRFs explain any of the excess cardiovascular risk in women with preterm birth.
