Abstract We aimed to evaluate the relationship between different lifestyle patterns and blood pressure. This study is based on the national survey of the risk factors for non-communicable diseases in Iran in 2012. A total of 8244 people aged 25–70 years old have been enrolled in the survey. Clustering on the individual data of lifestyle factors (nutrition, physical activity, and smoking) were carried out using self-organizing neural network method. Multivariable regression models were used to determine the relationship between blood pressure and the clusters. This study revealed seven lifestyle clusters in the national survey. The first cluster had a healthier lifestyle (15%), and the rest of the clusters had at least one or more lifestyle-related risk factors. Among all the clusters, people in two clusters, i.e. one characterized by consumption of sugar-sweetened beverages, salt, and fast foods, and the other one characterized by physical inactivity, were more exposed to the risk of hypertension (odds ratios of 1.44 and 1.12, respectively). People in another cluster who were 100% smokers and had a very high level of work-related physical activity were about 30% less likely to experience elevated blood pressure. Although a lifestyle with cigarette smoking was associated with a reduction in blood pressure, this might be due to other related factors, such as work-related physical activity, which lower blood pressure. Of course, this hypothesis still needs to be further studied in the future.

Background and Objective Metabolic syndrome (MetS) can be effectively prevented and treated by following healthy lifestyle practices. Healthy lifestyle management not only includes regulation of drinking and smoking, and regular physical activity but also health medical examinations. However, health medical examinations at private medical facilities involve high cost, limiting continuous and regular examination. The aim of this study is to analyze the prevalence of MetS and health management behavior according to the number of health medical examinations conducted in 14 years. Material and Methods According to the number of health medical examinations undertaken each year from 1999 to 2012, in 2012, 21,803 visitors (14,511 men and 7,292 women) from a health medical examination center at a private medical facility were assigned to low- (3–5 health examinations in 14 years), middle- (6–10 health examinations in 14 years), and high-frequency groups (11–14 health examinations for 14 years) and were classified by sex. Namely, they were divided into three groups: those who underwent 3–5 examinations, as low-frequency group, 6–10 examinations, as middle-frequency group, and 11-14 examinations, as high-frequency group. MetS was evaluated according to the criteria of the National Cholesterol Education Program and Adult Treatment Panel III and waist circumference was measured according to the standard for Asians by the World Health Organization. Odds ratio (OR) was calculated by logistic regression analysis. Results Systolic blood pressure tended to decrease to 124.5 versus 123.9 versus 123.5 mmHg in the low-, middle-, and high-frequency groups in men, respectively. In addition, the middle- and high-frequency groups demonstrated better total cholesterol, high-density lipoprotein, low-density lipoprotein, and systolic blood pressure compared with the low-frequency group. The prevalence of MetS demonstrated no significance before adjusting for variables in men, and high-frequency examinees demonstrated 18% low OR values (0.823, p < 0.001) after adjusting for age. OR was 0.868 (p = 0.015) when adjusted for age, other socio-economic factors, and health behavior. In women, the prevalence of MetS demonstrated significantly high OR of 1.205 (p = 0.007) and 1.300 (p = 0.008) in the middle- and high-frequency groups, respectively, but OR value decreased by 21% (0.791, p = 0.026) after adjusting for age. However, OR remained significant when adjusting for socioeconomic variables, physical activity, drinking, and smoking. For income and education, high-frequency examinees belonged to the high socioeconomic status group among men and women, but there were significant differences in walking among men with regard to physical activity (p < 0.001). Smoking was well-managed in the high-frequency group among men and women, and drinking showed a significant difference only in women (p < 0.001). Conclusion The high frequency of health medical examinations demonstrated low prevalence of MetS in men and women, and high socioeconomic status was associated with healthy behavior.

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.
