C-reactive protein levels according to physical activity and body weight for participants in the coronary health improvement project.

Objectives: To identify whether the Coronary Health Improvement Project (CHIP), an intervention designed to increase physical activity and improve diet, lowers serum C-reactive protein (CRP). The study will also assess whether changes in CRP over the study period are associated with baseline levels of and changes in selected coronary risk factors.

Methods: A randomized controlled study design assigned 348 individuals to the intervention or control group with measurements taken at baseline, 6 weeks, and 6 months of body weight, physical activity, and serum CRP levels.
