Background: The Systolic Blood Pressure Intervention Trial is a multicenter, randomized clinical trial of 9361 participants with hypertension who are ≥50 years old. The trial is designed to evaluate the effect of intensive systolic blood pressure control (systolic blood pressure goal <120 mm Hg) compared to standard control (systolic blood pressure goal <140 mm Hg) on cardiovascular events using commonly prescribed antihypertensive medications and lifestyle modification.
Objective: To describe the recruitment strategies and lessons learned during recruitment of the Systolic Blood Pressure Intervention Trial cohort and five targeted participant subgroups: pre-existing cardiovascular disease, pre-existing chronic kidney disease, age ≥75 years, women, and minorities.
Background: Population-based data to assess the extent of gastroparesis in the diabetic population are scarce. We examined the demographic and clinical characteristics associated with hospital admissions for diabetic gastroparesis in North Carolina.
Methods: Data from the 1998 North Carolina Hospital Discharge database were abstracted from records in which gastroparesis and diabetes mellitus were listed as simultaneous diagnoses.
Objectives: To determine if clustering of cardiovascular disease (CVD) risk factors has a differential impact on CVD and renal disease among African Americans compared to Whites with type 2 diabetes
Design: Cross-sectional.
Methods: Prevalent CVD, macroalbuminuria, and CVD risk factors were measured in 323 African-American and White adult patients with type 2 diabetes. CVD risk factors were dichotomized according to standard guidelines.
