• Status: Not Yet Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 50 (estimated)

• Sex: Male
• Age: 18 Years – 60 Years

Summary

Our goal is to explore the effectiveness of 9- month lifestyle medicine based coaching intervention (individual and group coaching) versus control (usual care/ written health instructions). The primary study outcomes will be mean changes in body composition metrics . Secondary outcomes will be the prevalence of metabolic abnormities, progression/regression of Metabolic Syndrome, push-up \& sit/stand capacity, self-reported physical activity, and quality of life/diet/sleep measures.

Detailed description

RATIONALE/GOALS: Obesity is a major health hazard in the US fire service. It contributes to excess cancer, cardiovascular disease and behavioral health issues. Obesity is negatively associated with 12/13 health priorities identified by the National Fallen Firefighter Foundation. Mitigating obesity is crucial to the fire service's goals of reducing chronic diseases and their adverse economic/operational impacts. METHODS: At least 75 male firefighters self-reporting a body mass index (BMI) of \>/= 30 kg/m2 AND interest in weight loss will complete a baseline health assessment including: lifestyle scores, body composition, metabolic/hormonal indices, physical fitness, and behavioral health screens, until 50 eligible firefighters have been consented and enrolled. After the initial clinical evaluation, 50 eligible firefighters will be randomized into the two study groups (about 25 firefighters to each arm): 1. General Health Instructions (CONTROL) and 2. Individual \& Group Lifestyle Coaching based on the six pillars of Lifestyle Medicine \& Full Plate Living. Participants will repeat the all health/fitness measures at 3-, 6- and 9-months post study entry. The two treatment groups will be compared on an intention to treat basis. ANTICIPATED OUTCOMES: Compared to CONTROL, firefighters receiving the Lifestyle Coaching Intervention should achieve significantly greater improvements in body composition, metabolic \& other health measures, as well as adopt healthy lifestyle behaviors.
