Background: Many active duty personnel struggle with becoming overweight during the course of their active duty service.  This can lead to difficulty in maintaining fitness standards, a decrease in overall functioning and an increased risk for chronic disease.  Few published studies exist that evaluate interventions aimed at weight loss and chronic disease prevention in the active duty population specifically.  The Group Lifestyle Balance (GLB) program has been shown to be effective in facilitating weight loss and reducing chronic disease risk in civilian populations.  However, the effectiveness of this class in active duty populations is not known.  Furthermore, the effectiveness of existing lifestyle intervention programs, such as the Fitness Improvement Program (FIP) and the Better Body Better Life (BBBL) program within the Air Force Medical Service is unknown.  Purpose: To examine the effectiveness of the GLB program compared with the currently available FIP and BBBL on the following health indicators: individual physical fitness as measured by change in weight; abdominal circumference and minutes engaged in physical activity; changes in risk associated with chronic disease as measured by changes in lipid and HbA1c levels; and changes in self-perception of function and well-being as measured by the RAND SF-36 questionnaire.  Methods: 131 participants will be enrolled and randomized to one of the three intervention groups.  Data are collected at 3 time points: baseline,           3 months and 6 months.  Data will be compared between the three groups using a one-way ANOVA tests, regression modeling and Kruskal Wallace tests as is appropriate to the different outcome measures.  Results: To date, 51 participants have been enrolled and 28 have completed the study. Preliminary analyses show no significant differences in demographic characteristics and baseline measurements between the three groups.  Not enough data has been collected yet to determine differences in outcome measures.  Military Nursing Implications:  Evidence from this study could be used by military nurses to plan appropriate interventions for overweight active duty personnel.  In addition, military nurses could use this evidence to advise military leaders on programs that might positively affect the health and fitness of active duty members.
