Abstract：Objective To study the blood pressure level and its influencing factors in elderly patients with hypertension.Methods 111 elderly patients with hypertension hospitalized in department of geriatrics of the Affiliated Hospital of North China University of Science and Technology from April to September 2015 were included (45 males, 66 females, age 80~96). According to blood pressure, patients were divided into the controlled group (less than or equal to 150/90mmHg) and the uncontrolled group (over 150/90mmHg). Data including general information (age, sex, level of physical activity, regularity of drug taking and so on), lipids fat, fasting glucose and uric acid were collected. Short-form of Mini-nutritional Assessment (MNA-SF), Pittsburg Sleep Quality Index (PSQI) and Hamilton Anxiety Rating Scale (HAM-A) were used to test patients.Results Compared with the controlled group, age, percentage of males, uric acid level and PSQI score were increased, the proportion of regular medication and the proportion of active physical exercise were decreased, the difference was statistically significant (P<0.05). The results of regression analysis showed that female (OR=4.854,95%CI:1.324~17.875) is the risk factor of uncontrolled hypertension in elderly patients, regular medication (OR=0.044,95%CI:0.012~0.166), low blood uric acid (OR=0.983,95%CI:0.971~0.994) and good quality sleep (OR=0.745,95%CI:0.599~0.926) were the protective factors.Conclusion Elderly hypertensive patients with regular medication, lower blood uric acid level and good quality sleep may have higher rate of controlled blood pressure, female elderly hypertensive patients may have higher rate of uncontrolled blood pressure.
