Nearly 40% of mortality in the United States is linked to social and behavioral factors such as smoking, diet and sedentary lifestyle. Autonomous self-regulation of health-related behaviors is thus an important aspect of human behavior to assess. In 1997, the Behavior Change Consortium (BCC) was formed. Within the BCC, seven health behaviors, 18 theoretical(More)
OBJECTIVE PHLAME's (Promoting Healthy Lifestyles: Alternative Models' Effects) objective was to assess and compare two means to promote healthy lifestyles. METHODS Prospective trial among 599 firefighters randomized by station to 1) team-centered curriculum, 2) one-on-one motivational interviewing (MI), and 3) controls. Assessment included dietary(More)
This study investigated the mediating mechanisms responsible for the effects of a program designed to reduce intentions to use anabolic steroids, improve nutrition, and increase strength training self-efficacy. Fifteen of 31 high school football teams (N = 1,506 players at baseline) in Oregon and Washington were assigned to receive the intervention. The(More)
To assess potential long-term effects of weight loss on resting metabolic rate (RMR), the RMRs of seven obese women were measured by indirect calorimetry before weight loss, during a protein-sparing modified fast, and for 2 mo while at a stable reduced weight. Body composition was also determined at each interval. RMR significantly decreased 22% (p less(More)
We studied the intraocular pressure response to short-term maximal aerobic exertion before and after exercise conditioning in ten healthy sedentary volunteers. Before exercise conditioning, mean intraocular pressure +/- S.E.M. decreased by 5.9 +/- 0.6 mm Hg after short-term maximal aerobic exercise, returning to baseline in a mean of 37 +/- 4 minutes. After(More)
This paper examines the mechanisms by which PHLAME (Promoting Healthy Lifestyles: Alternative Models' Effects), a health promotion intervention, improved healthy eating and exercise behavior among firefighters, a population at high risk for health problems due to occupational hazards. In a randomized trial, 397 firefighters participated in either the PHLAME(More)
OBJECTIVE To develop and test a school-based intervention to prevent anabolic androgenic steroid use among high-risk adolescent athletes. DESIGN Nonrandom controlled trial. SETTING Two urban high schools. PARTICIPANTS Fifty-six adolescent football players at the experimental school and 24 players at the control school. INTERVENTION Eight weekly,(More)
Athletes with a higher intent to use anabolic steroids were similar to students who indicated no predisposition to use steroids on economic, academic, and physical measures. They had similar understandings of anabolic steroid effects, and their self-rated understandings of how to weight train and of sports nutrition were similar. In addition, the influence(More)
OBJECTIVE To determine the characteristics of female US high school students reporting anabolic steroid use. DESIGN Cross-sectional assessment using the 2003 Centers for Disease Control and Prevention national school-based Youth Risk Behavior Survey database. SETTING Nationally representative sample of US high schools. PARTICIPANTS Female students in(More)
OBJECTIVE To describe effects of 2 worksite health promotion programs for firefighters, both immediate outcomes and the long-term consequences for 4 years following the interventions. METHODS At baseline, 599 firefighters were assessed, randomized by fire station to control and 2 different intervention conditions, and reevaluated with 6 annual follow-up(More)
