Clinical effectiveness of the LE³AN program: A military healthy lifestyle program

For several decades, obesity has been a major health concern within the general population of the United States as well as within the unique military population. Unlike the civilian sector, military service requires individuals to meet weight and body fat standards. In order to assist overweight military personnel return to standards, Tripler Army Medical Center initiated the LE³AN Program. LE³AN is a one-week, day-treatment, cognitive-behavioral weight management program coupled with 12 months of weekly follow-up. Baseline data was collected on 387 consecutive participants. Despite physical fitness training and required standards in each military service, the average BMIs for men and women were in the obese range, with male participants' BMIs significantly higher than women's (34.3 vs 31.9, p < .005). One year outcome data was collected from 167 participants, i.e. 43.2% of treatment initiators. Among participants who completed treatment, men maintained a 6.56% loss of their initial weight while women maintained a 7.35% loss. Over a quarter, 26.6%, of those who started the program (but did not complete it) maintained at least a 5% weight loss at one year, while 61.6% of treatment completers maintained 5% weight losses.
