Sensory-based nutrition pilot intervention for women

Area of Science:

• Behavioral Science
• Nutrition Science
• Psychology

Background:

• Restrained eating, characterized by dieting and weight control concerns, has negative effects on eating behaviors.
• There is a need for positive strategies to promote healthy eating habits.
• Sensory-based interventions may offer a novel approach to address these issues.

Purpose of the Study:

• To investigate the influence of a sensory-based intervention on eating-related attitudes and behaviors in restrained women.
• To assess changes in reliance on physical hunger and satiety signals.
• To evaluate the intervention's impact on disinhibition and intuitive eating.

Main Methods:

• Pilot randomized controlled trial with 50 women in Quebec City, Canada.
• Intervention group received sensory-based intervention; control group was on a waiting list.
• Validated questionnaires (Restraint Scale, TFEQ, MEQ, IES) administered at baseline, end of intervention, and 12 weeks post-intervention.
• Statistical analysis using mixed models to assess group, time, and group-by-time interactions.

Main Results:

• The intervention group showed a significant decrease in Three-Factor Eating Questionnaire-Disinhibition (TFEQ-D) and a significant increase in Mindful Eating Questionnaire-Disinhibition (MEQ-D).
• Significant increases in Intuitive Eating Scale-Unconditional Permission to Eat (IES-UPE) were observed in the intervention group.
• Improvements were sustained at 12 weeks post-intervention.

Conclusions:

• Sensory-based intervention shows promise for improving eating attitudes and behaviors in restrained women.
• This approach may enhance intuitive eating and reduce disinhibited eating without worsening restrained eating.
• Further research is warranted to confirm these preliminary findings.
