Abstract
The JDCP study is a large-scale observational study to investigate the current status of management of people with diabetes in recent years, and to clarify the risk factors for the onset/progression of diabetes complications. This study includes a total of 6,338 patients aged 40~<75 years old who had received regular outpatient treatment from 2007~2009 at medical facilities nationwide specializing in diabetes. The primary endpoints for the study include occurrence/progression of nephropathy, retinopathy, neuropathy, macroangiopathy, and periodontal disease, and the secondary endpoints include occurrence of malignancy and mortality. The current report describes an outline of the study, and a summary of baseline data for the participating patients with type 2 diabetes (n=5,944). The baseline characteristics were as follows: males 60.1 %; mean age 61.4 years-old; duration of diabetes 10.8 years; family history of diabetes 52.8 %; BMI 24.5 kg/m2; HbA1c 7.4 % (achievement of<7.0 %, 40.6 %); blood pressure 129.8/74.8 mmHg; non-HDL-C 137.6 mg/dl. Treatment includes diet therapy alone 10.4 %, oral hypoglycemic agents 62.1 %, and insulin therapy 27.5 %. The cohort is to be followed up for at least 5 years, with a high follow-up rate. The study keeps focusing on making registry reliable and versatile, as well as bringing resulting research findings and insights to bear on treatment guide for diabetes.
