Relationship and interactions between elevated fasting glucose and hypertension for cardiocerebral vascular disease / 中华心血管病杂志

<p><b>OBJECTIVE</b>To explore the relationship and interaction of elevated fasting glucose and hypertension on cardiocerebral vascular disease.</p><p><b>METHODS</b>10 054 males and females were recruited for our cross-sectional study during May 2007 to August 2007. Unconditional logistic regression was used to analysis the relationship between fasting glucose and hypertension on cardiocerebral vascular disease. A product of fasting glucose and hypertension was added to the logistic regression model to evaluate the multiplicative interaction and relative excess risk of interaction (RERI), attributable proportion (AP) of interaction and synergy index (S) was applied to evaluate the additive interaction of the two factors. Bootstrap was used to calculate 95% confidence intervals (CI) of RERI, AP and S.</p><p><b>RESULTS</b>After adjusting age, gender, smoking, drinking, body mass index (BMI) and region, the product of fasting glucose and hypertension was not statistically significant, which means there was no multiplicative interaction between the two. But the additive indexes RERI, AP and S with 95%CI of diabetes and hypertension were 0.64 (0.03, 1.25), 0.27 (0.01, 0.47) and 1.83 (1.02, 5.13) respectively, which means significant additive interaction was shown between the two on cardiovascular disease but not no stroke. And there were no additive interaction between impaired fasting glucose on cardiovascular disease or stroke.</p><p><b>CONCLUSIONS</b>Hypertension was independently related to cardiovascular disease and stroke in Beijing citizens, and diabetes were independently related to stroke. There was additive interaction between diabetes and hypertension on cardiovascular disease.</p>

Association between marital status and prevalence of peripheral arterial disease among Beijing residents: a cross-sectional study / 中华心血管病杂志

<p><b>OBJECTIVE</b>To investigate the relationship between marital status and prevalence of peripheral arterial disease (PAD) among Beijing residents.</p><p><b>METHODS</b>From May to August 2007, 10 054 residents were interviewed to collect demographic and biochemistry information. Generalized linear mixed model was used to determine the relationship between marital status and prevalence of PAD in terms of OR and corresponding 95% confidence intervals.</p><p><b>RESULTS</b>After adjusting the traditional risk factors including age, area, lipid, serum glucose, blood pressure, central obesity, smoking, drinking and physical activities for PAD, relationship between marital status and prevalence of PAD was found both at the female and male groups of those with 45 years or older. Compared with married men, OR and 95% confidence interval of PAD for unmarried men were 1.56 (0.39 - 6.35) and 1.61 (0.77 - 3.35) for those with 45 years younger and older respectively, while compared with married women, OR and 95% confidence interval of PAD for unmarried women were 0.75 (0.22 - 2.57) and 1.78 (1.23 - 2.58) for those with 45 years younger and older respectively. Significant differences (all P < 0.01) were found between married and unmarried women of 45 years or older in terms of age, waist circumstances, systolic blood pressure, fasting glucose, total cholesterol, low-density lipoprotein and smoking.</p><p><b>CONCLUSIONS</b>Peripheral arterial disease was related to marital status for women of 45 years or older among Beijing residents. Estrogen level and the distribution of other PAD risk factors might contribute to the observed finding.</p>

Hypertension and cardiovascular risk evaluation of Chinese cardiovascular physicians / 中华心血管病杂志

<p><b>OBJECTIVE</b>To observe the prevalence, awareness, treatment and control rate of hypertension and to evaluate the 10-year absolute risk of coronary heart disease(CHD) and ischemic cardiovascular disease(ICVD) in Chinese cardiovascular physicians.</p><p><b>METHODS</b>A total of 4032 cardiovascular physicians (28 to 79 years old) from 386 hospitals in 31 provinces, autonomous regions and municipalities were randomly selected and received an epidemiologic survey of prevalence, awareness, and control of hypertension and evaluations of CHD and ICVD risk.</p><p><b>RESULTS</b>The prevalence of hypertension in Chinese cardiovascular physicians was 13.1%. The awareness rate of hypertension in Chinese cardiovascular physicians was 81.7%. Hypertension treatment rate was 69.6% and blood pressure control rate was 44.6%. The prevalence of hypertension was higher in male physicians than in female physicians before the age of 55 years old. Ten-year absolute risk of CHD and ICVD was 0.08 and 0.03 in hypertensive physicians compared to 0.03 and 0.01 in non-hypertensive physicians.</p><p><b>CONCLUSIONS</b>The results show suboptimal awareness, treatment and control rate in Chinese cardiovascular physicians for their own hypertension status.Physicians suffering from hypertension face higher risk for cardiovascular disease. It is therefore necessary to improve the self-monitoring of blood pressure in Chinese cardiovascular physicians.</p>
