The relations of abnormal pulse pressure to the cardiovascular risk factors and the cardiac function in adults from Hebei, Zhejiang, and Guangxi province of China.

To explore the correlations of abnormal pulse pressure (PP) with the cardiovascular risk factors and cardiac functions by analyzing the distributions of abnormal PP in Han adults aged 18-74 years in Hebei, Zhejiang, and Guangxi province to provide evidence for health management. A cross-sectional study was carried out in three provinces of China. Multi-phase, stratified, unequal proportional and cluster sampling was adopted to investigate the data obtained from 12,795 Han adults aged 18-74 years. The prevalence of cases with abnormal PP in the three provinces was 6.7 %. Abnormal PP was significantly associated with a number of cardiovascular risk factors including location, age, gender, and education (P < 0.05). Results from multivariable logistic regression analysis showed that abnormal PP was positively associated with age and BMI. Compared with the normal subjects, there was a statistically significant difference in the mean of high-normal blood pressure, IFG divided by gender and LCW (P < 0.05). There was no significant difference in the mean of high-normal TC, TG, and LDL-C and low-normal HDL-C (P > 0.05). Age has also been found to be a statistically significant factor (P < 0.05). Abnormal PP was common in Chinese Han adults aged 18-74 years, which was independently associated with cardiovascular risk factors and cardiac functions. Health management for Han adults with abnormal PP was strongly suggested.
