Abstract
Background
Interventions targeting weight-related experiential avoidance (EA) and disinhibited eating (DE) may also improve diet quality. Participants with overweight/obesity and DE who recently completed a behavioral weight-loss program were randomized to receive acceptance and commitment therapy or continued behavioral weight-loss treatment. In this secondary analysis, we explored (1) change in diet quality from baseline to 6-month follow-up (FU) and (2) whether weight-related EA at baseline and (3) change in weight-related EA during treatment were related to change in diet quality from baseline to FU.
Method
Veterans (N = 68) completed food frequency questionnaires at baseline and FU, which were used to generate diet quality scores on the healthy eating index-15 (HEI-15). Weight-related EA was assessed using the Acceptance and Action Questionnaire for Weight-Related Difficulties-Revised (AAQW-R) at baseline, post-treatment, and FU. Aims were examined with mixed ANOVA analyses.
Results
Across both treatment groups, HEI-15 scores declined from baseline to FU. Women’s HEI-15 decreased by about 5 times that of men. Baseline AAWQ-R was negatively associated with change in HEI-15. Neither AAWQ-R at post-treatment nor change in AAQW-R from baseline to post-treatment was significantly associated with change in HEI-15 at FU.
Conclusions
Greater weight-related EA at baseline was associated with lower diet quality at FU, but change in weight-related EA during treatment did not predict change in diet quality at FU. Interventions targeting DE and weight-loss may require specific components to improve and sustain healthy dietary intake in Veterans with obesity and DE.
