Evaluation of the Navy's obesity treatment program

Area of Science:

• Military Health and Wellness
• Obesity Treatment Efficacy
• Behavioral Health Interventions

Background:

• Obesity presents a significant health challenge within military populations.
• Effective, scalable obesity treatment programs are crucial for maintaining force readiness.
• The U.S. Navy implemented a three-tiered obesity treatment program to address this issue.

Purpose of the Study:

• To evaluate the overall effectiveness of the Navy's three-tiered obesity treatment program.
• To compare the effectiveness of the three distinct treatment levels.
• To identify the most successful components for sustained weight management.

Main Methods:

• A cohort of 369 U.S. Navy program participants were enrolled.
• Measurements of height, weight, and body circumference were collected at baseline and follow-up points (6 weeks, 6 months, 12 months).
• Statistical analysis compared outcomes across the three treatment tiers, controlling for initial body fat percentage.

Main Results:

• All three treatment tiers demonstrated significant and sustained reductions in percent body fat.
• Absolute fat loss at 12 months was modest (-3.7% for men, -4.5% for women).
• The Level III tier, utilizing a multidimensional approach, showed superior effectiveness, even when accounting for baseline differences.

Conclusions:

• The Navy's tiered obesity program shows promise, with Level III being the most effective.
• Further enhancements to treatment approaches and long-term, behaviorally-based aftercare are recommended.
• Focusing on multidimensional strategies and sustained support may improve long-term obesity management outcomes.
