Abstract : Purpose: To test a nurse coaching intervention and an herbal supplement for Service Member (SM) weight reduction over a 12-week period to evaluate their effectiveness independently and synergistically. Design: Prospective, randomized placebo-controlled trial. Methods: Overweight SM, 18-57 years old, recruited from the Army overweight program, were randomized to one of 4 groups. Self-referrals not yet flagged for being overweight attended 12 weeks of dietitian-led lifestyle education. Primary outcome was weight loss, and secondary outcomes were % body fat, waist circumference, fasting blood sugar (FBS), lipid and vitamin D levels, bone mineral density (BMD), adherence, and motivation. Outcome measures were obtained at 3 time points. A nurse coach contacted participants weekly. Adherence was measured by classes attended and returns for data collection/blood draws. Sample: Demographics (N=435): mean age 30 8.2 yrs, 73.4% male, predominantly white (70.1%) and non-Hispanic (80%), 71% married, 91% enlisted, and 61% reported history of being overweight. Analysis: Change scores were compared across groups using general linear models adjusted for covariates imbalanced at baseline. Findings: 1) When comparing the 3 nurse health coaching (NHC) groups to the control group (CG) only, beneficial intervention effects were observed for heel BMD (d = 0.3), vitamin D levels (d = 0.43), and FBS (d = -0.4); 2) Supplement group showed no difference on any outcome; 3) There were no significant differences in any outcome between the CG and the self-referred group. Attrition rate was highest from Week 6 to 12 at 40%. Implications for Military Nursing: The primary outcome of weight loss proved difficult for all groups; similar motivation and adherence scores were recorded, excluding the CG. The education provided to participants about good health behaviors may diminish chronic disease risk and the related socioeconomic burden.
