We need to know the precise distributions of BP and factors affecting BP. <strong>Data and Methods</strong><strong>:</strong> The distributions of BP are analyzed using 12,877,653 observations obtained from the JMDC Claims Database. The factors that may affect the BP are analyzed by the regression models using 4,615,346 observations. <strong>Results:</strong> The averages of systolic BP (SBP) and diastolic BP (DBP) are 120.4 and 74.2 mmHg with standard deviations of 15.9 and 11.3 mmHg, respectively. Among the nonmodifiable factors, age and gender are important factors. Among the modifiable factors, variables related to obesity are important risk factors. Taking antihypertensive drugs makes SBP and DBP 13.4 mmHg and 7.8 mmHg lower. <strong>Conclusion:</strong> The criteria of BP should be carefully determined considering age and gender. The effects of age may be a little different for SBP and DBP. It is necessary to use the proper model to evaluate the effect of antihypertensive drugs correctly. <strong>Limitations:</strong> The dataset is observatory. Although there are various types of treatment methods and antihypertension drugs, their effects are not evaluated.展开更多

Methods: In this study, we investigated the association between different classic antihypertensives and the development of NOF in the elderly. This was a longitudinal cohort study performed using data from claim forms submitted to the Taiwan Bureau of National Health Insurance in Central Taiwan, China including case patients with NOF aged 65–80 years from January 2002 to December 2012 and non-NOF controls. Prescriptions for antihypertensives before the index date were retrieved from a prescription database. We estimated the hazard ratios (HR s) of NOF associated with antihypertensive use. Non-NOF controls served as the reference group. Results: A total of 128 patients with NOF were identified from among 1144 patients with hypertension during the study period. The risk of NOF after adjusting age, sex, comorbidities, and concurrent medications was higher among the users of angiotensin-converting enzyme (ACE) inhibitors (HR, 1.64; 95% confidence interval [CI], 1.01–2.66) than among nonusers. Patients who took calcium channel blockers (CCBs) (HR, 0.70; 95% CI, 0.49–0.99) were at a lower risk of developing NOF than nonusers. Loop diuretics, thiazide diuretics, angiotensin receptor blocker, beta-blocker, and alpha-blocker were not associated with the risk of NOF. Conclusions: Elderly with hypertension who take CCBs are at a lower risk of NOF and that the use of ACE inhibitors was associated with a significantly increased risk of developing NOF during the 11-year follow-up.展开更多
