Mediators of intervention effects on dietary fat intake in low-income overweight or obese women with young children
Copyright © 2020 Elsevier Ltd. All rights reserved..
PURPOSE: We investigated whether autonomous motivation and self-efficacy might mediate the association between a lifestyle behavior intervention and dietary fat intake in low-income overweight or obese women with young children.
METHODS: Participants were randomized to an intervention or comparison group. Intervention participants received a 16-week intervention aimed to prevent weight gain through promotion of stress management, healthy eating and physical activity. During the intervention phase, participants viewed a designated video lesson at home and dialed in a peer support group teleconference every week (weeks 1-4) then every other week (weeks 5-16). Potential mediation effects were analyzed using sequential mixed-effects linear models and path analysis.
RESULTS: The intervention led to increased autonomous motivation (β = 0.34, standard error [SE] = 0.15, P = 0.005), which subsequently increased self-efficacy (β = 0.18, SE = 0.35, P < 0.001), and higher levels of self-efficacy were associated with decreased dietary fat intake (β = -0.22, SE = 0.28, P < 0.001). In other words, autonomous motivation and self-efficacy mediated the association between the lifestyle behavior intervention and dietary fat intake.
CONCLUSION: To decrease dietary fat intake for low-income overweight or obese women with young children, strategies, such as those promoting peer encouragement, may be warranted in interventions to enhance autonomous motivation and/or practical skills for increasing self-efficacy.
