Clinical significance of analysis of the level of blood fat, CRP and hemorheological indicators in the diagnosis of elder coronary heart disease. Saudi J Biol Sci 2018; 25:1812-1816. [PMID: 30591805 PMCID: PMC6303158 DOI: 10.1016/j.sjbs.2018.09.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2018] [Revised: 09/03/2018] [Accepted: 09/03/2018] [Indexed: 12/02/2022] Open
Abstract
Objective To investigate the levels of blood fat, C-reactive protein (CRP) and hemorheological indicators in the elder patients with coronary heart disease (CHD), so as to provide evidence for prospective study and treatment of elder CHD. Methods We collected the clinical data of 127 elder CHD patients who admitted to this hospital between July 2016 and December 2017 to detect the levels of blood fat, CRP and hemorheological indicators. Results In elder CHD patients, levels of the total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterin (LDL-C) were significantly higher than the normal reference, and comparison with the control group also showed significant increases (p < 0.01); average levels of the high-density lipoprotein cholesterin (HDL-C), phospholipid (PL), lipoprotein a [LP (a)] and free fatty acid were in the range of normal reference. Abnormal levels of TC, TG, LDL-C and HDL-C were identified in 59.06%, 58.27%, 51.18% and 18.11% of the elder CHD patients, most of which were concomitant with obesity or hypertension, and levels of these indicators were significantly higher than those in the control group with statistically significant differences (p < 0.01). Comparisons of the age, gender distribution, hypotension, exercise and sleep showed that differences had no statistical significance (p > 0.05). In comparison with the control group, the levels of CRP, the whole blood viscosities at high and low shears, plasma viscosity, hematocrit value, aggregation index and rigidity index of red blood cells (RBC) were all higher than those in the control group, and the differences had statistical significance (p < 0.01). However, the erythrocyte sedimentation rate (ESR), deformity index of RBC, blood flow rates in the bilateral middle cerebral arteries (MCA), anterior cerebral arteries (ACA), terminal internal carotid artery (TICA), posterior cerebral arteries (PCA), vertebral arteries (VA) and basilar artery (BA) were significantly lower than those in the control group, and the differences had statistical significance (p < 0.05 or 0.01). Conclusion In elder CHD patients, anomaly is mainly seen in levels of TC, TG and LDL-C with concentrated, adhesive and aggregating blood.

Abstract
AIMS We aimed to determine the prevalence of diagnosed and undiagnosed diabetes, risk factors affecting the healthy population, and factors that increase diabetes risk in the adult northeast Turkish population. METHODS Using population proportional cluster sampling, 930 adults were selected. After excluding people with diabetes, risk screening was conducted in the healthy population (n: 825) using the Information Form and FINDRISK questionnaire. Fasting venous blood and biochemical parameters were measured. RESULTS Prevalence of diabetes was 13.6% (new % 2.3), translating to approximately 44 thousand adults. Among the healthy population, 37.5% had high risk. Prevalence of not exercising (78.2%), obesity (36.1%), and hypertension (24.5%) were high. Predictors of risk of diabetes were aging (OR 1.09), low education (OR 0.51), familial diabetes history (OR 15.27), not exercising (OR 0.41), obesity (OR 5.17), high waist circumference (OR 1.05), heart disease (OR 4.81), and hypertension (OR 2.60). CONCLUSIONS This study can stimulate early screening for cardiovascular diseases and hypertension and initiating aggressive treatments in people with high diabetes risk. In primary health services, number of doctors and nurses trained in diabetes should be increased and dieticians should be involved. People with high risk should receive lifestyle regulations training.

Assessment of cardiometabolic risk among shift workers in Hungary. Health Qual Life Outcomes 2012; 10:18. [PMID: 22296806 PMCID: PMC3295687 DOI: 10.1186/1477-7525-10-18] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2011] [Accepted: 02/01/2012] [Indexed: 11/10/2022] Open
Abstract
AIM Shift workers may be at risk of different diseases. In order to assess cardiometabolic risk in shift workers, a cross-sectional study was performed among active workers. METHODS A total of 481 workers (121 men, 360 women) were investigated; most of them were employees in light industry (58.2%) or in public services (23.9%). Past medical history was recorded and physical examination was performed. Questionnaires were used to characterize daily activity. Fasting venous blood sample was collected for measuring laboratory parameters. Data from shift workers (n = 234, age: 43.9 ± 8.1 years) were compared to those of daytime workers (n = 247, age: 42.8 ± 8.5 years), men and women were analyzed separately. RESULTS In men, systolic blood pressure was higher in shift workers compared to daytime workers (133 ± 8 vs 126 ± 17 mmHg; p < 0.05). In women, weight (73.6 ± 15.5 vs 67.7 ± 13.2 kg; p < 0.001), body mass index (27.5 ± 5.7 vs 25.0 ± 4.3 kg/m2; p<0.001) and the prevalence rate of hypertension in the past medical history (24.4 vs 13.4%; p < 0.01) were higher in shift workers compared to daytime workers. In addition, the proportion of current smokers was higher (37.7 vs 21.7%; p < 0.001) and HDL-cholesterol level was lower (1.56 ± 0.32 vs 1.68 ± 0.36 mmol/l; p < 0.01) in female shift workers than in female daytime workers. Both in men and in women, rotating shift workers spent less time sleeping both on working days and on non-working days, spent less time with sport activity, drank more coffee and they spent less time working per day, especially in light physical work, compared to daytime workers. In addition, low and middle educational levels were most frequently found among rotating shift workers as opposed to the daytime workers where high educational level was more common. CONCLUSION Middle-aged active shift workers, especially women, have a less healthy lifestyle and are at higher cardiometabolic risk as compared to daytime workers. Our study highlights the importance of measures for identifying and preventing cardiometabolic risk factors in shift workers.

Abstract
BACKGROUND This study investigates ethnic disparities in metabolic syndrome in Malaysia. METHODS Data were obtained from the Malaysia Non-Communicable Disease Surveillance-1 (2005/2006). Logistic regressions of metabolic syndrome health risks on sociodemographic and health-lifestyle factors were conducted using a multiracial (Malay, Chinese, and Indian and other ethnic groups) sample of 2,366 individuals. RESULTS Among both males and females, the prevalence of metabolic syndrome amongst Indians was larger compared to both Malays and Chinese because Indians are more likely to exhibit central obesity, elevated fasting blood glucose, and low high-density lipoprotein cholesterol. We also found that Indians tend to engage in less physical activity and consume fewer fruits and vegetables than Malays and Chinese. Although education and family history of chronic disease are associated with metabolic syndrome status, differences in socioeconomic attributes do not explain ethnic disparities in metabolic syndrome incidence. The difference in metabolic syndrome prevalence between Chinese and Malays was not statistically significant. Whereas both groups exhibited similar obesity rates, ethnic Chinese were less likely to suffer from high fasting blood glucose. CONCLUSIONS Metabolic syndrome disproportionately affects Indians in Malaysia. Additionally, fasting blood glucose rates differ dramatically amongst ethnic groups. Attempts to decrease health disparities among ethnic groups in Malaysia will require greater attention to improving the metabolic health of Malays, especially Indians, by encouraging healthful lifestyle changes.

Abstract
OBJECTIVES Describe the prevalence of metabolic syndrome, and its association with contemporary lifestyle factors. SUBJECTS AND METHODS In 2004-2005, 4,296 subjects of the 1982 Pelotas Birth Cohort were evaluated, and metabolic syndrome (MetS) was assessed in 3,599 according to the NCEP-ATP III and IDF criteria. RESULTS Prevalence of MetS was 5.9% and 6.7% for NCEP-ATPIII and IDF, respectively. Smoking, alcohol intake, and physical activity were not associated with MetS. Among men, the body mass index (BMI) was associated with MetS - overweight [RR: 3.14 (95% CI, 1.97-5.00)] and obese subjects [RR: 17.41 (95% CI, 11.85-25.60)]. In women, family income and schooling were inversely associated with MetS, overweight increased the risk of MetS 7.73 (95% CI, 3.65-16.38) times and obesity 40.67 (95% CI, 20.85-79.33) times. CONCLUSIONS MetS was more prevalent among men according to NCEP-ATP III criteria, and obesity was the main risk factor.

Abstract
Recent studies indicate a high prevalence of increased QTc interval length in patients affected by the metabolic syndrome, but there is no data available to demonstrate the correlation of the QTc interval with severity of the cardiometabolic syndrome (CMS). The objective of this study was to estimate the association between increasing number of cardiometabolic abnormalities and increasing QTc interval length. Electrocardiograms were collected from 1420 participants in a cross-sectional study. The QTc interval lengths were corrected for heart rate using Bazett's formula. CMS was determined according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) guidelines. Multiple linear regression models were used examining associations between increasing number of individual components of syndrome with QTc interval length. Participants with CMS had significantly longer QTc interval length, controlling for age, body mass index (BMI), sex, and ethnic group. Increasing number of CMS components was significantly associated with increased QTc interval length, even after adjusting for age, BMI, total cholesterol, fasting C peptide, and history of heart disease. These findings suggest that QTc interval length is increased in the presence of CMS and is linearly related to an increase in number of metabolic abnormalities.

Abstract
A low educational level and a poor socioeconomic status could be associated with increased risk for chronic diseases. The aim of the study was to evaluate the relationship between the educational level and cardiometabolic risk in adult patients with type 1 diabetes (n = 437; age: 38.0 +/- 10.4 years, duration of diabetes: 19.2 +/- 11.1 years; x +/- SD). Educational levels were classified as low [primary school, n = 56 (12.8%)], middle [high school, n = 251 (57.4%)] or high [university, n = 130 (29.7%)]. The prevalence rate of the metabolic syndrome proved to be higher in patients with low versus high educational levels (ATP-III criteria: 42.9 vs. 21.5%, P = 0.0006). Antihypertensive treatment and cardiovascular diseases were more prevalent in patients with low versus high educational level (46.4 vs. 26.2%, P = 0.01; 12.5 vs. 2.3%, P = 0.02; respectively). Overall glycemic control was worse in patients with low versus high educational level (HbA(lc): 8.8 +/- 1.6 vs. 7.9 +/- 1.4%; P = 0.0006). Patients with low versus high educational level differed significantly regarding smoking habits (smokers: 28.6 vs. 11.6%; P = 0.01) and regular physical activity (5.4 vs. 33.1%; P = 0.0001). Higher prevalence rate of certain cardiometabolic risk factors was associated with low educational level in middle-aged type 1 diabetic patients with relatively long duration of diabetes; therefore, these patients should have priority when preventing cardiovascular complications.

Abstract
Metabolic syndrome (MS) is more common among socio-economically disadvantaged individuals and is associated with certain risky lifestyle practices. MS also appears to be triggered by adverse social circumstances and chronic stress. The present paper reviews accumulating evidence to imply that individuals who have certain personality and behaviour traits are particularly predisposed to develop MS, and brings together theories that relate to possible psychological mechanisms underlying MS. It considers how such factors might interact causally to encourage the development of MS. As part of the EU-funded LIPGENE Integrated Project, multi-level modelling will be undertaken to explore potential pathways to MS, taking into consideration the interplay between a range of psycho-social, demographic, cultural and lifestyle factors thought to contribute to the development of MS. Data will be gathered for this purpose from a representative sample of >50-year-olds living in Britain (n 1000) and Portugal (n 500). It is anticipated that this information will assist in the development and targetting of future intervention to prevent and treat MS in the normal population.

Abstract
A population-based case-control proband study was undertaken to elucidate familial aggregation, independent environmental factors, and the interaction between them. A total of 7308 metabolic syndrome (MET-S) cases were identified from the Keelung community-based integrated screening programme between 1999 and 2002. The study has a case-control/family sampling design. A total of 1417 case probands were randomly selected from 3225 metabolic syndrome cases and the corresponding 2458 controls selected from 16,519 subjects without metabolic syndrome by matching on sex, age (+/-3 years) and place of residence. The generalized estimation equation model was used to estimate odds ratios and corresponding 95% confidence intervals. The risk for having metabolic syndrome among family members for cases versus control probands was 1.56-fold (1.29-1.89) after controlling for significant environmental factors. Higher risk of metabolic syndrome was found in parents than spouse. Low education against high education had 2.06-fold (1.36-3.13) risk for metabolic syndrome. Betel quid chewing was positively associated with the risk of MET-S, with 1.99-fold (1.13-3.53) risk for 1-9 pieces and 1.76-fold (0.96-3.23) risk for >or=10 pieces compared with non-chewer. Moderate and high intensity of non-occupational exercise led to 21.0% (OR=0.79 (0.63-0.98)) and 26.0% (OR=0.74 (0.59-0.94)) reduction in the risk for metabolic syndrome, respectively. The frequent consumption of vegetable reduced 24.0% (OR=0.76 (0.62-0.92)) risk for MET-S. The frequent consumption of coffee was associated the increased risk for metabolic syndrome (OR=1.32 (1.07-1.64)). The present study confirmed the risk of metabolic syndrome not only has the tendency towards familial aggregation but is affected by independent effect of environmental or individual correlates.

Abstract
BACKGROUND To evaluate the prevalence of the metabolic syndrome (MS) and its components in a population-based cohort, and to analyse the association between gender, environmental conditions, C-reactive protein (CRP), and the syndrome. METHODS Out of 1877 subjects aged 45-64, who represented all the patients of six family physicians, representative of the sanitary districts of Asti (north-western Italy), 88% accepted to participate in an interview on personal habits, and several clinical and laboratory measurements. RESULTS The MS (National Cholesterol Education Program criteria) was present in 24% of males and 22% of females. Males had a significantly higher percentage of hyperglycaemia, hypertension, hypertriglyceridemia, whereas females had a higher prevalence of central obesity and low HDL-cholesterol. In a multiple logistic regression model, the MS was significantly associated with increasing age, BMI, and >30 g/day alcohol intake (OR = 1.42; 95% CI 1.27-1.58), and negatively to higher education level (OR = 0.52; 95% CI 0.28-0.99) and moderate exercise (OR = 0.65; 95% CI 0.57-0.76). CRP levels are highly correlated to BMI and the components of the syndrome. The association between CRP and the MS remains significant in women only, in a multivariate analysis, after multiple adjustments (OR = 1.73; 95% CI 1.42-2.11). Higher CRP levels, correlated to smoking and, inversely, to alcohol intake, identify a further 12% of the cohort at higher cardiovascular risk. CONCLUSIONS The MS affects more than 20% of this middle-aged cohort, but more than 30%, with higher CRP levels are at high cardiovascular risk. Healthier lifestyle habits are inversely associated with the MS and CRP levels, suggesting the need for strategies and their implementation in the general population.

Abstract
BACKGROUND Most of the evidence about socioeconomic inequalities in the metabolic syndrome comes from Western industrialized societies. The aim of this study is to examine how the inequalities appear and what could explain them in Korea, a rapidly changing society. METHODS We analysed the nationwide survey data of 1998 and 2001 with a sample of 4630 men and 5896 women (> or = 25 years). The subjects were grouped into four birth cohorts based on the historical context: born before 1946, 1946-53, 1954-62, and since 1963. Socioeconomic position was defined by education level: high school graduation or above as the more educated group, and below that as the less educated one. The syndrome was defined according to ATP III criteria using abdominal obesity for Asians. The covariates included family history of diabetes, smoking, drinking, daily physical activity, regular exercise, suicidal ideation, weight change, and carbohydrates intake. The associations were examined by stratified logistic regression models across cohorts and gender. RESULTS Less-educated women had higher prevalence with widening gaps across successive cohorts; the age-adjusted odds ratios of the less-educated group were 1.22 (0.86-1.71), 1.41 (1.01-1.97), 2.50 (1.87-3.35), and 2.64 (1.69-4.14). They hardly changed after covariate adjustment, and remained significant with considerable attenuation after controlling body mass index. However, educational disparities were not observed in men. CONCLUSIONS We could observe the complex pattern of disparities in the metabolic syndrome across cohorts and gender. An equity-sensitive health promotion programme to prevent further spread of social inequalities may have beneficial effects on the metabolic syndrome and its components in Korea.

Abstract
BACKGROUND Previous studies have shown socioeconomic inequalities in the metabolic syndrome and coronary heart disease (CHD), but it is not known whether educational disparities in the metabolic syndrome explain educational inequalities in CHD. We investigated this question in a prospective study of middle-aged men and women. METHODS Baseline data were collected in 1992 in Finland from 864 men and 1045 women aged 45-64 years without history of CHD. A total of 113 new CHD cases were identified by the end of 2001. Logistic and Cox regression models were used in data analysis. RESULTS The metabolic syndrome defined by NCEP criteria was less prevalent in subjects with university education (21% in men and 14% in women) compared with basic level education (41% and 27%, respectively). Adjusting for health behavioural factors had only a slight effect on the educational gradient in the metabolic syndrome. An educational gradient in CHD incidence was clear [hazard ratio (HR) = 0.67 95% confidence interval (CI) 0.48-0.94, men and women combined]. Adjustment for the metabolic syndrome attenuated this gradient only slightly, but when individual components of the metabolic syndrome were included as covariates the attenuation was more substantial (HR = 0.73 95% CI 0.52-1.04). CONCLUSIONS Educational differences in the metabolic syndrome and CHD incidence are clear. Metabolic risk factors explain the gradient in CHD incidence partly, but only when they are treated as independent risk factors. Screening for the metabolic syndrome alone is not sufficient to account for socioeconomic inequalities in cardiovascular disease.
