BACKGROUND: In a proof-of-concept trial, a phenotype tailored lifestyle intervention (PLI) led to greater weight loss than a standardized lifestyle intervention (SLI). This secondary analysis evaluated the effect of the PLI for individuals with an emotional eating phenotype (EE) on weight loss outcomes, eating behaviors and mood.
METHODS: This original clinical research article is a secondary analysis of a 12-week, non-randomized, date-of-treatment trial in which adults with obesity underwent phenotyping and were assigned sequentially to either a PLI (N = 84) or a SLI (N = 81). The EE phenotype was defined as a HADS-A (Hospital Anxiety and Depression Scale for Anxiety) score ≥7. Weight loss outcome and changes in eating behaviors and mood were evaluated among participants with EE assigned to an SLI (n = 19) or a PLI (n = 26).
RESULTS: Participants with EE assigned to the PLI achieved greater weight loss at 12-weeks compared with those assigned to the SLI (-5.9% ± 4.4 vs. -2.6% ± 4.8; p = 0.02). Participants with EE assigned to the PLI demonstrated reduced HADS-A and HADS-D scores, and the Three-Factor Eating Questionnaire Emotional Eating subscale (TFEQ-EE), while those assigned to the SLI had minimal or no improvements after 12-weeks. Among participants with EE assigned to the PLI, Higher HADS-A scores and lower scores in the Weight Efficacy Lifestyle questionnaire (WEL) negative emotions subscale and TFEQ-EE at baseline were associated with greater weight loss at 12-weeks. (NCT04073394).
CONCLUSION: These findings support tailoring behavioral weight-loss interventions for adults with obesity and EE. Larger randomized studies with longer follow-up are needed to further refine phenotype-based approaches.
