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 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.

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.

Noncommunicable Diseases (NCDs) merupakan salah satu penyebab kematian utama di dunia. Kurangnya aktivitas fisik dapat meningkatkan risiko penyakit ini. Meskipun telah banyak penelitian yang menyelidiki tentang hubungan aktivitas fisik dan faktor risiko penyakit kardiovaskuler, hanya terdapat beberapa penelitian di Indonesia yang menelaah tentang peran aktivitas fisik dalam perkembangan penyakit kardiovaskuler. Penelitian ini bertujuan untuk mendeskripsikan tentang tingkat aktivitas fisik dan menyelidiki hubungannya dengan faktor risiko penyakit kardiovaskuler pada karyawan kantor di lingkungan Universitas Sebelas Maret (UNS). Penelitian ini menggunakan desain penelitian potong lintang, dengan jumlah sampel sebanyak 44 orang. Data level aktivitas fisik diperoleh dari International Physical Activity Questionnaire (IPAQ). Sedangkan faktor-faktor risiko penyakit kardiovaskuler (gula darah, kolesterol, tekanan darah, lingkar pinggang, dan IMT) diukur dengan menggunakan alat ukur yang sesuai. Hasil penelitian menunjukkan bahwa level aktivitas fisik karyawan berkategori Rendah sebesar 6.82%, Sedang sebesar 72.73%, dan Tinggi sebesar 20.45%. Berdasarkan uji Pearson Correlation, tekanan darah baik sistolik dan diastolik mempunyai hubungan yang signifikan dengan level aktivitas fisik. Tidak ada hubungan yang signifikan antara level aktivitas fisik dengan faktor risiko lainnya dalam penelitian ini. Secara umum penelitian ini menunjukkan bahwa level aktivitas fisik karyawan di lingkungan UNS adalah berkategori sedang, dan tekanan darah mempunyai hubungan yang signifikan dengan aktivitas fisik. Physical activity level and cardiovascular risk factors among university employees AbstractNoncommunicable Diseases (NCDs) are one of the leading deaths in the world. Insufficiency of physical activity (PA) escalate the risk of NCDs. Although the reports of the studies investigating the relationship between PA and cardiovascular risk factors are abundance, only a few studies in Indonesia examined the role of PA in the development of cardiovascular diseases. The aim of this study was to describe the level of PA and investigate the relationships between PA and cardiovascular risk factors among UNS employees. This was a cross sectional study with a sample of 44 university employees. PA level was assessed using IPAQ. Meanwhile cardiovascular risk factors such as plasma glucose, cholesterol, blood pressure, waist circumference, and BMI were measured using an appropriate tool for each measure. The results revealed that participants with low level of PA (6.82%), moderate category (72.73%), and high category (20.45%). Pearson Correlation analysis showed blood pressure both systolic and diastolic had a significant association with PA level. There was no a significant association between PA level and others cardiovascular risk factors in this research. Generally, this study exhibited the level of PA among UNS employees in the moderate category, and blood pressure had a significant association with PA.

Physical activity (PA) and exercise training (ET) are highly effective in the prevention of cardiovascular disease (CVD) via improvement of cardiovascular risk factors (CV RFs), such as blood pressure (BP), lipid profile, glycaemic control, body fat mass, and inflammation. In the first part of this chapter, we describe the currently observed effects of PA and exercise intervention on these RFs. In the second part, we explain which exercise modalities should be selected to optimize these CVD RFs, especially for those patients with multiple CVD RFs.

Physical activity is an important component of cardiovascular health. The fact that physical activity is also associated with a substantial number of cognitive and academic benefits, therefore schools teachers can be an important role model in promoting a physically-active lifestyle in school children. The aim of this study is to examine the levels of physical activity (PA) and its association with cardiovascular risk factors in a sample of school teachers. Forty-nine (n=49) teachers from primary and secondary schools around Klang Valley urban areas were recruited. The PA level was determined using pedometer, worn for three consecutive days. Anthropometric measurements and blood samples were collected to determine cardiovascular risk factors. Findings showed that the school teachers recorded an overall mean (± SEM) of 7707 ± 490 steps/day, which is below the recommended target of 10 000 steps per day. According to pedometer-determined physical activity indices proposed by Tudor-Locke and Bassett (2004), 20.83% of the sample were classified as ‘sedentary’ (<5000 steps/day), 35.40% were ‘low active’ (5000 – 7499 steps/day) and only 18.70% achieved more than 10 000 steps/day. According to Asian BMI cut-off points, 43% of the teachers were categorized as overweight and obese (>23 kg/m2). The mean values for waist circumference, fasting blood sugar, and cholesterol level, systolic and diastolic blood pressure were 83.96 ± 1.90 cm, 5.41 ± 0.26 mmol/l, 4.64±0.26 mmol/l, 118.90 ± 1.72 mmHg and 72.40±1.58 mmHg respectively. Fisher Exact Test shown that there were significant association between daily step and age category. Daily steps weakly negative correlated with systolic blood pressure (r = -0.024, p > 0.05) as well as blood sugar levels (r = -0.061, p> 0.05), diastolic blood pressure (r = -0.079, p> 0.05), body mass index (r = -0.271, p> 0.05), waist circumference (r = -0.196, p> 0.05), as well as blood cholesterol levels (r = -0.037, p> 0.05). In conclusion, there were weak negative correlations between steps per day and cardiovascular risk factors. Generally, the level of physical activity in the sample of teachers needs to be improved. Interventions aimed at promoting PA among school teachers may be warranted in the future.

CONTEXT AND OBJECTIVE: Studies have demonstrated that metabolic complications from child obesity, although silent, increase the risk of development of cardiovascular diseases in adulthood. The present paper sought to describe the prevalence of overweight/obesity and analyze the possible relationship between obesity and other cardiovascular risk factors among children and adolescents. DESIGN AND SETTING: Cross-sectional study, conducted in a university. METHODS: The study included 564 children and adolescents, aged 8 to 17 years. Body mass index and waist circumference were used to evaluate obesity. Other cardiovascular risk factors were evaluated, like systolic and diastolic blood pressure, glycemia, triglycerides and total cholesterol. Descriptive analysis was used for sample characterization, the chi-square test for categorical variables and Pearson's linear correlation for evaluating the relationship between obesity indicators and other cardiovascular risk factors. RESULTS: High prevalence of overweight/obesity was found among the schoolchildren (25.3% among the boys and 25.6% among the girls), along with abdominal obesity (19.0%). The overweight/obese schoolchildren presented higher percentages for the pressure and biochemical indicators, compared with underweight and normal-weight schoolchildren. Body mass index and waist circumference showed a weak correlation with the variables of age and systolic and diastolic blood pressure (P < 0.001), but there was no correlation between these obesity indices and biochemical variables. CONCLUSION: The high prevalence of overweight/obesity and its relationship with other cardiovascular risk factors demonstrate that it is necessary to develop intervention and prevention strategies from childhood onwards, in order to avoid development of chronic-degenerative diseases in adulthood.
