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.

5.Pathophysiology of Postprandial Hyperglycemia.
Journal of Korean Diabetes 2012;13(1):15-17
The high incidence of atherosclerosis and cardiovascular disease is the leading cause of morbidity and mortality among diabetic patients. It is well known that postprandial hyperglycemia is an independent risk factor for diabetic complications and mortality. For better management of diabetic patients, effort must be put forth to not only achieve the HbA1c target, but also to control postprandial hyperglycemia. This article reviews the pathophysiology and clinical aspects of postprandial hyperglycemia to appropriately control blood glucose level.

6.Risk Factors Management in Diabetic Patients
Journal of Korean Diabetes 2019;20(3):157-169
Diabetes mellitus is associated with a high frequency of complications related to cardiovascular disease as well as microvascular complications such as nephropathy, retinopathy, and neuropathy. Prevention of these vascular complications is the main issue for diabetic patients. Hyperglycemia, hypertension, and dyslipidemia are well-known risk factors for complications in diabetic patients. Moreover, these chronic conditions are often seen in many diabetic patients. So, multifactorial interventions are needed to manage these risk factors and prevent diabetic complications. However, there is still a debate about the optimal level required for glycemic control, the appropriate blood pressure target, and dyslipidemia management. Although many countries have written their own guidelines, there are some discrepancies between these different guidelines. Recently, the Korean Diabetic Association issued new guidelines for Korean diabetic patients. Here, I will introduce these new guidelines and discuss the optimal management of risk factors such as hyperglycemia, hypertension, and dyslipidemia in diabetic patients.

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.

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.
