Abstract

Objective The purpose of this study was to determine the effect of the MOVE! weight management program on Veterans body weight and body mass index (BMI) up to two years after baseline.
Design This study was a retrospective cohort study conducted by chart extraction of data, for the years 2008-2012. The treatment included a 12-week MOVE! class followed by monthly aftercare appointments. Data were extracted from the time of baseline weight up to two years after baseline weight for the MOVE! and control groups.
Participants This study compared Veterans who participated in the MOVE! class series and subsequent aftercare treatment (n=60) to a control group of Veterans who received no treatment (n=60).
Main Outcome Measures The main outcome measure of this study was to determine the difference in mean weight and BMI at one year and two years after baseline between the MOVE! and control groups. The secondary outcome measure was to determine the difference in mean hemoglobin A1c, fasting blood glucose, total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL) and triglyceride levels between the treatment and control group one year after baseline.
Statistical Analyses This investigation was a repeated measures analysis. An informal test of normality and test for outliers were conducted to verify assumptions prior to model fitting. The general linear model was implemented to model the mean structure by specification of the fixed effects. Covariance structures between subjects as well as within subjects were discussed and tested. The final mean model is fitted accounting for the most appropriate covariance structure and statistical inferences are made based on the final fitted model. The critical level was set at alpha=0.05 for statistical significance.
Results The mean age was 62.0 +1.4 years for the control group and 61.5 +0.9 years for the treatment group. The majority of both groups were Caucasian males. MOVE! participants demonstrated a significant weight loss compared to the control group at one year and two years after baseline. The difference in weight between groups at one year was 31.7 +9.7 pounds (p=0.0013) and the difference between groups at two years was 28.0 +9.7 pounds (p=0.0046). Hemoglobin A1c, total cholesterol, and HDL all demonstrated statistically significant improvements from baseline to one year. Fasting blood glucose, LDL, and triglycerides did not change significantly from baseline to one year.
Conclusions The results of this study indicate MOVE! was an effective tool for Veterans to lose weight and improve glucose control and lipid profile.
