Abstract P072: Early Response Predicts One-Year Weight-Reduction Goal Achievement with MOVE!®
Introduction: Previous reports suggested that age, gender, race, and participation predicted weight reduction in the weight-reduction program, MOVE!®, available at Veterans Administration Medical Centers. It is not known if early response to the MOVE!® program predicts continued participation or weight reduction.
Hypothesis: We assessed the hypothesis that early weight reduction success with MOVE!® would predict ongoing participation and weight-reduction goal achievement at one year.
Methods: Using longitudinal clinical data from electronic health records of 107 MOVE!® program participants with 1-month and 1-year data, MOVE!® sessions and weight reduction were examined in this secondary analysis. Participation was based on group session attendance. Attending 14 or more sessions within the first 6 months was selected as a participation cut point based on the 2013 guidelines for overweight and obesity management. Early response was based on at least 1% weight reduction from baseline at week four. Weight-reduction success at one year was based on at least 5% reduction from baseline.
Results: Participants were 59.3 (SD=11.1, SEM=1.1) years of age on average; female 13% (14 of 107); African American 54% (58 of 107); Caucasian 46% (49 of 107); with a mean BMI of 35.5(SD=5.0, SEM=0.49) and attended 7.3 (SD=4.9 , SEM=0.5) sessions on average. Total 6-month group session participation was not explained by early weight reduction success (t = 0.81; CI -1.11, 2.63; p = .42). Early responders were no more likely to participate in 14 or more MOVE!® sessions within 6 months than participants who were not early responders (OR = 1.2; CI 0.34, 4.20; p = .78). Early responders were seven times as likely to achieve at least the 5% weight reduction goal at one year compared to those participants who were not early responders, while controlling for age, gender, race, and total group sessions (OR = 6.96; CI 1.85, 26.13; p = .004).
Conclusions: Early response was a significant predictor of at least 5% weight reduction goal achievement at one year. However, early response was not a predictor of participation or ongoing participation reaching 14 sessions in 6 months. Further study is needed to determine genetics as well as other predictors of early response to MOVE!®.
