A mindful eating intervention: A theory-guided randomized anti-obesity feasibility study with adolescent Latino females

While pediatric anti-obesity lifestyle interventions have received considerable attention, few show sustained impact on body mass index (BMI). Using the Information-Motivation-Behavioral Skills Theory as a framework, we examined the effects of a satiety-focused mindful eating intervention (MEI) on BMI, weight and mindful awareness.

Design and setting: Utilizing a two-group, repeated measures design, 37 adolescent females with a BMI >90th percentile, recruited from a public high school in a Latino community in the Southwestern United States, were randomized 2:1, one third to the group receiving a 6-week MEI and two thirds to the comparison group (CG) receiving the usual care (nutrition and exercise information).

Intervention: During six weekly 90-min after school MEI group sessions, the behavioral skills of slow intentional eating were practiced with foci on satiety cues and triggers to overeat.

Outcomes: Feasibility and acceptability were measured as participant retention (goal ≥55%) and evaluative comments from those in the MEI group, respectively. BMI and mindful awareness were measured on site at baseline, immediately post intervention, and at 4-week follow-up (week 10).

Results: Fifty-seven and 65% of those in the MEI and CG were retained throughout the study, respectively. MEI participants showed significantly lowered BMI compared with CG participants, whose weight increased (p<0.001). At six weeks, the MEI group BMI decreased by 1.1kg/m(2) (BMI continued to decline to 1.4kg/m(2) by week 10); while CG BMI increased by 0.7kg/m(2) (consistent with BMI >90th percentile standard growth projections).

Conclusions: Initial and sustained decline of BMI in the MEI group supports further study of this theory-guided approach, and the value of practicing satiety-focused mindful eating behavioral skills to facilitate health behavior change.
