Research Summary

APPROACHES TO PREVENT CARDIOVASCULAR DISEASE The overall goals of Dr. Natarajan's research in cardiovascular disease (CVD) prevention are to improve cardiovascular disease risk assessment and to optimize ways to prevent CVD.

He uses several methodological approaches: 1. ANALYSIS OF LARGE POPULATION-BASED DATABASES. He works with national databases to answer questions relevant to preventing cardiovascular disease. By analysis of such large databases, he examined trends in screening, prevalence and treatment of CVD risk factors using the behavioral risk factor surveillance system, compared variations in health care utilization among adults with CVD risk factors using the Medical Expenditure Panel Survey, determined the validity of self-report of hypercholesterolemia using the National Health and Nutritional Examination Survey III, and evaluated gender differences in CHD mortality in individuals with diabetes using the Framingham data.

2. Currently, he is focused on conducting RANDOMIZED CONTROLLED TRIALS (RCT's) TO EVALUATE BEHAVIORAL INTERVENTIONS. He evaluated the association of transtheoretical stages of change constructs with glycemic control and blood pressure control in low-income patients with CVD risk factors, and is using the transtheoretical framework in other studies. He is conducting a RCT to definitively test the effect of a stage-matched behavioral intervention on treatment adherence and hypertension control in collaboration with experts in behavioral theory.
