Promoting Healthy Lifestyles: Alternative Models' Effects (PHLAME) is a research study to evaluate and compare two ways to promote healthy behaviors, (regular physical activity, less than 30% calories from fat, 5 or more servings of fruits plus vegetables each day and maintain a healthy weight). Unhealthy nutrition practices and sedentary (inactive) lifestyles are the two most common harmful behaviors in the United States. Our two health promotion methods are 1) a team-based approach and 2) a one-on-one approach involving meetings with a health counselor. A third group only receives the same evaluation and their results and is the control group. Study participants are firefighters from 36 fire stations in Oregon and Washington. The goals of the study are increased physical activity and fitness, improved nutrition, and improved energy balance (reduced body fat). Changes in these factors can help lower risks for heart disease, some types of cancer, diabetes, hypertension and musculoskeletal injuries. Results from PHLAME will provide information on how best to help adults achieve and maintain healthy lifestyles.
Doctors recommend that young children participate in daily physical activity to promote bone health. However, studies in adults show that physical activity and increased calcium intake cause noticeable benefits for bone health only when both factors occur together. The goal of this study is to find out whether calcium intake changes the response of bone to activity in children 3 to 4 years old. Children will participate in one of two programs conducted in childcare centers 5 days a week for 1 year. One program will involve activities that use large muscles (gross motor activity). The other will involve activities using small muscles (fine motor activity). We will give a calcium supplement (1 gram per day) to half of the children in each program and give the other half an inactive pill. We will measure bone mass and bone mineral density at the beginning and end of the study. We will take measurements 12 months after the program's completion to see if physical activity and/or calcium supplements have long-term effects on bone mineral density and physical activity.
