Filter by:The investigators propose to conduct a randomized controlled trial at the patient level of the Telephone Linked Care - Behavioral Change (TLC-BC) system, which is designed to promote smoking cessation, reduce risky drinking, and improve physical activity and diet. They expect to: 1. successfully integrate an automated telephone behavior change intervention into primary care practices; 2. demonstrate improvement in health behaviors for individuals randomized (assigned by systematic chance) to use the TLC-BC system compared to individuals who receive written health education informational packets; and 3. evaluate the direct costs associated with the use and operation of the TLC-BC system. Project aims and hypotheses follow: Aim 1: Integrate a proven, totally automated computer telephone intervention, Telephone Linked Care - Behavior Change (TLC-BC), into primary care practices. This will be assessed by the patient and clinician/staff surveys at the end of data collection. Aim 2: Demonstrate an improvement in health behaviors for individuals randomized to use the TLC-BC system compared to individuals who receive written informational packets. Aim 3: Evaluate the direct costs associated with the use and operation of the TLC-BC system within the primary care setting. Hypothesis 1: The Telephone Linked Care - Behavioral Change system will be successfully implemented by patients and practices. Hypothesis 2: At 6 months a clinically significant improvement in behavioral change rates will be demonstrated for diet, physical activity, and smoking in the intervention group compared to patients in the control group. Hypothesis 3: At baseline, 3, 6, and 9 months risky drinking will be identified, but there will be no difference in improvement between the study groups.
The purpose of the proposed study is to determine the effect of walking to school for one week on total physical activity and patterns of physical activity in third, fourth and fifth grade students.
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.
