OBJECTIVETo explore the relationship between the occupational stress and cardiovascular disease risk factors.
METHODSThe subject was 93 male freight train dispatchers, the occupational stressors, personalities, and occupational strain response were measured by using questionnaires. Blood pressure, heart rate, the concentrations of the cholesterol, triglyceride, and glycosylated hemoglobin in blood serum were also measured.
RESULTSSocial support score were significantly positively related to systolic pressure (r = 0.22) and diastolic pressure (r = 0.30) (P < 0.05), while job satisfaction negatively related to them and concentration of triglyceride (r = -0.37, -0.47 and -0.28 respectively, P < 0.05, P < 0.01), and self-esteem negatively to systolic pressure (r = -0.21, P < 0.05). The differences in diastolic pressure [(78.5 +/- 13.1), (83.6 +/- 8.2), (88.1 +/- 12.3), (85.8 +/- 9.8) mm Hg, P < 0.05] among groups of social support score, body mass index (BMI) (P < 0.01) among groups of job difficulty the differences in systolic pressure [(124.9 +/- 14.4), (129.7 +/- 13.1), (118.4 +/- 16.4), (133.5 +/- 23.1) mm Hg] and diastolic pressure [(85.5 +/- 11.3), (87.0 +/- 9.8), (80.1 +/- 10.1), (88.9 +/- 12.0) mm Hg] and cholesterol level in serum [(4.96 +/- 1.18), (5.39 +/- 0.85), (5.00 +/- 1.15), (4.34 +/- 0.91) mmol/L] among groups of vulnerability to stress (P < 0.05), as well as the difference in systolic pressure and glycosylated hemoglobin level in serum among groups of competition score (P < 0.05) were all statistically significant. Stepwise regression analysis showed that job time demands and negative coping affected the change of cholesterol (R(2) > 0.05); the job relation decision latitude, social support, job difficulty, personality (self-esteem and anxiety trait) and negative coping were the predictors of smoking (R(2) > 0.05). Heart rate was related to home income and competition factor of Type A Behavior (R(2) = 0.06).
CONCLUSIONThe psychosocial stress aspects of work may be related to some cardiovascular risk factors.

BACKGROUND:
Current practice uses the latest measure of glycated hemoglobin (HbAlc) to facilitate clinical decision-making. Studies have demonstrated that HbAlc variability links the risk of death and complications of diabetes. However, the role of HbAlc variability is unclear in clinical practice. This systematic review summarized the evidence of visit-to-visit HbAlc variability regarding different metrics in micro- and macro-vascular complications and death in people with type 2 diabetes.
METHODS:
We searched PubMed, EMBASE (via OVID), and Cochrane Central Register (CENTRAL, via OVID) for studies investigating the association between HbAlc variability and adverse outcomes in patients with type 2 diabetes and performed random-effects meta-analysis stratified by HbAlc variability metrics in terms of standard deviation (SD), coefficient of variation (CV), and HbAlc variability score (HVS).
RESULTS:
In people with type 2 diabetes, the highest quantile of all three HbAlc variability metrics (HbAlc-standard deviation [HbAlc-SD], HbAlc-coefficient of variance [HbAlc-CV], and HVS) is associated with increased risks of all-cause mortality, cardiovascular events, progression to chronic kidney disease, amputation, and peripheral neuropathy. For example, the hazard ratio of HbAlc-SD on all-cause mortality was l.89 with 95% confidence interval (95% CI) l.46-2.45 (HbAlc-CV l.47, 95% CI l.26-l.72; HVS l.67, 95% CI l.34-2.09).
CONCLUSIONS
High HbAlc variability leads to micro- and macro-vascular complications of type 2 diabetes and related death. People with type 2 diabetes and high HbAlc variability need additional attention and care for the potential adverse outcomes.

Surveys of noncommunicable diseases were performed in six communities in Papua New Guinea during 1985-1986. Results are reported here with respect to blood pressure and associated factors in adults. Mean systolic and diastolic blood pressures were lowest, and hypertension was rarest (less than 2%), in three rural/semirural villages on Karkar Island, Madang Province. Intermediate values for blood pressure and moderate prevalence of hypertension (3-6%) were observed in rural and urban Tolai communities in East New Britain Province. A periurban village in the Eastern Highlands Province displayed the highest mean blood pressures and prevalence of hypertension (12% in men and 5% in women). There was a modest rise in mean systolic blood pressure with age in most groups, but the age-related rise in diastolic pressure was much less pronounced. Other cardiovascular risk factors--body mass index (BMI), and plasma cholesterol, glucose and insulin concentrations--were lowest in the least developed rural villages on Karkar Island and highest in the urban Tolai and periurban highland communities. Both systolic and diastolic blood pressures were significantly (and positively) related to age, male sex, BMI and speaking a non-Austronesian language. It is concluded that there is now a considerable variation in the prevalence of hypertension, and the levels of blood pressure and other cardiovascular risk factors, in different communities in Papua New Guinea.

OBJECTIVETo investigate the role of non-high density lipoprotein cholesterol (non-HDL-C) in the assessment of cardiovascular disease (CVD) risk factors such as hypertension, pre-diabetes and diabetes in obese children.
METHODSAccording to the presence of complications (hypertension, pre-diabetes and diabetes), 810 children with central obesity were divided into two groups: one group with complications (n=499) and one group without complications (n=311). One hundred and sixty-four age- and sex-matched children served as the control group. Logistic regression analysis and receiver operating characteristic (ROC) curves were used to analyze the detection of non-lipid CVD risk factors by seven lipid markers.
RESULTSThe prevalence rates of hypertension and pre-diabetes were significantly higher in obese children with high non-HDL-C concentrations (≥3.76 mmol/L). After adjusting for waist circumference Z-scores, the area under the ROC curve for non-HDL-C was 0.680 to detect non-lipid CVD risk factors, while the areas for low-density lipoprotein cholesterol, total cholesterol and apoprotein B were 0.659, 0.669 and 0.647 respectively.
CONCLUSIONSCompared with the other lipid markers, non-HDL-C is a better predictor for non-lipid CVD risk factors in obese children. Measurement of non-HDL-C concentations is recommended for obese children.

OBJECTIVE:
We investigated the influence of obstructive sleep apnea -hypopnea syndrome (OSAHS) on hypertension and metabolism.
METHOD:
There were two groups in this research; they were the research group including 115 patients who were diagnosed with polysomnography and the control group of 122 healthy persons. The blood pressure in the morning, plasmas glucose (GLU), total cholesterol (TC), triglyceride (TG), and uric acid (UA) were measured. There were 32 moderate or severe OSAHS patients and 20 healthy persons were selected to be measured the mitochondrial coupling factor 6 (CF6) with radio-immunity method. The results were analyzed with statistic method. The P < 0.05 means the significant difference.
RESULT:
The patients' blood pressure in the morning was significantly higher than the control healthy persons. The plasmas glucose, total cholesterol, triglyceride, and uric acid of the OSAHS patients were all in a higher level than those of the control group healthy persons. There were significant differences between the two groups. The mitochondrial coupling factor 6 (CF6) of moderate OSAHS patients or severe OSAHS patients was more than that of the healthy persons (P < 0.05).
CONCLUSION
OSAHS is a potential risk factor on the cardiovascular diseases and the metabolism disorders. The mitochondrial coupling factor 6 (CF6) may play an important role in the procedure of X syndrome.

BACKGROUNDIncreased blood pressure and elevated total cholesterol (TC) level are the two most important modifiable risk factors of cardiovascular disease (CVD) in the world. Hypertension and hypercholesterolemia co-exist more often than would be expected and whether there is a synergistic impact on fatal CVD between elevated TC and hypertension need to be further examined in Chinese population.
METHODSWe conducted a cohort study which recruited 5092 Chinese male steelworkers aged 18 - 74 years in 1974 - 1980 and followed up for an average of 20.84 years. Totally 302 fatal CVD events were documented by the year of 2001. Cox proportional hazards regression models were undertaken to adjust for baseline variables with fatal CVD events as the outcome variable. Additive interaction model was used to evaluate the interaction between elevated TC and hypertension.
RESULTSHypercholesterolemia and hypertension were significantly associated with an increased hazard ratio (HR) of fatal CVD (1.67 (95%CI 1.18 - 2.38) and 2.91 (95%CI 2.23 - 3.80) respectively. Compared to participants with normotension and TC < 240 mg/dl, the HRs were 1.11 (95%CI 0.56 - 2.21), 2.74 (95%CI 2.07 - 3.64) for hypercholesterolemia and hypertension respectively, and 5.51 (95%CI 3.58 - 8.46) for participants with both risk factors. There was an additive interaction with a 2.65 (95%CI 0.45 - 4.85) relative excess risk (RERI) between hypercholesterolemia and hypertension on CVD.
CONCLUSIONWe found that the risk of fatal CVD was significantly associated with an additive interaction due to hypercholesterolemia and hypertension besides a conventional main effect derived from either of them, which highlights that the prevention and treatment of both risk factors might improve the individual risk profile thus reduce the CVD mortality.

OBJECTIVEObese children and adolescents are often complicated with the abnormalities of lipid and glucose metabolism, which are often associated with adulthood hypertension, diabetes and cardiovascular disease. In this study, the blood lipids, blood pressure and carotid arterial intima-media thickness (IMT) in obese children and adolescents were measured to investigate the relationship between the dyslipidemia and early vascular lesions.
METHODA total of 580 obese children and adolescents aged from 7 to 17 years of age were enrolled from 3 hospitals from Jan. 2008 to Sept. 2009. They were divided into 2 groups according to their blood lipoid levels. Ortholiposis group included 100 males and 52 females with a mean age of 10.47 years and a mean body mass index (BMI) of 28.28 kg/m(2). Dyslipidemia group included 305 males and 123 females with a mean age of 10.83 years and a mean BMI of 27.60 kg/m(2). Physical examination, and measurement of blood lipid, glucose and liver enzyme were taken. Carotid IMT was measured for 285 subjects.
RESULT(1) Hypertension was found in 12.5% (19/152) and 20.1% (86/428) patients in ortholiposis and dyslipidemia groups, respectively, with a significant difference (χ(2) = 4.362, P = 0.037). The OR was 1.760 with 95% confidence interval of 1.030 - 3.008. Higher prevalence of hypertension was found in patients with dyslipidemia. (2) The left, right and mean common carotid IMTs of dyslipidemia group were higher than those of ortholiposis group without significant difference (all P > 0.05). The left, right and mean internal carotid IMTs in dyslipidemia group were (0.66 ± 0.15) mm, (0.65 ± 0.15) mm and (0.65 ± 0.15) mm, respectively while these in ortholiposis group were (0.62 ± 0.13) mm, (0.60 ± 0.13) mm and (0.61 ± 0.12) mm, respectively (P < 0.05 for all). (3) Bivariate correlation analysis showed that systolic blood pressure was positively correlated with age, BMI, BMI Z score, waist circumference, hip circumference, uric acid, alanine transaminase, triglyceride, fasting insulin and insulin resistance index (P < 0.05 for all). Moreover, mean carotid and internal carotid IMTs were positively correlated with age, BMI, waist circumference, hip circumference, and triglyceride (all P < 0.05). Multiple linear regression analysis showed that hip circumference and insulin resistance index were independent determinants of systolic pressure. Waist circumference was independent determinant of mean common and internal carotid IMT and triglyceride was independent determinants of mean internal carotid IMT.
CONCLUSION(1) Vascular lesions, including hypertension and thicker tunica intima are common in obese children and adolescents. (2) Vascular lesions are closely related with dyslipidemia, and waist circumference and hypertriglyceridemia are the risk factors.
