Purpose: Investigate the associations between psychosocial factors and physical activity. Design: Secondary data analysis utilizing baseline data of a large-scale community-based randomized controlled lifestyle behavior intervention. Setting: The Special Supplemental Program for Women, Infants, and Children in Michigan, USA. Subjects: Low-income overweight or obese mothers with young children (N = 740, 65% response rate). Measures: Survey data were collected via phone interview. Predictors included self-efficacy, autonomous motivation, emotional coping, and social support. Self-reported leisure physical activity was the outcome variable. Covariates were age, race, smoking, employment, education, body mass index, and postpartum status. Analysis: A multiple linear regression model was applied. Results: Self-efficacy (β =.32, 95% CI =.11,.52, P =.003) and autonomous motivation (β =.10, 95% CI =.03,.17, P =.005) were positively associated with physical activity. However, emotional coping and social support were not associated with physical activity. Conclusion: Future research should examine the longitudinal association of key psychosocial factors with physical activity. [ABSTRACT FROM AUTHOR]

Background. Episodic future thinking (EFT) has shown efficacy in laboratory settings. We conducted a pilot goal-oriented EFT (GoEFT) intervention in a real-world setting to help low-income overweight or obese mothers lose weight. This paper presents intervention acceptability and efficacy. Methods. The study used a single-group, before–after design. During the 3-week intervention, participants (N = 15) completed weekly web-based lessons and online health coaching sessions to manage stress and emotion, eat healthier, and be more physically active. Participants completed online surveys at baseline and immediately after the intervention. They also completed an interview to evaluate intervention acceptability. We applied paired t-tests to evaluate efficacy and used content analysis to discover interview themes. Results. Participants consistently identified the intervention as acceptable, noting the usefulness of pre-written goals, GoEFT strategies, and goal progress evaluations. The intervention effectively promoted weight loss (d = −0.69), fruit and vegetable intake (d = 0.45–0.49), and emotion control (d = 0.71). It also reduced fat (d = −0.51) and added sugar intake (d = −0.48) and alleviated stress (d = −0.52). Moreover, the intervention increased autonomous motivation (d = 0.75–0.88) and self-efficacy (d = 0.46–0.61). Conclusion. The GoEFT intervention was acceptable to participants, showing strong preliminary efficacy. [ABSTRACT FROM AUTHOR]

Background: Mothers In Motion (MIM), a community-based lifestyle behavioral intervention, was designed and conducted to help low-income overweight and obese young mothers prevent further weight gain via promotion of stress management, healthy eating, and physical activity. This paper presents intervention effect on body weight (primary outcome) and summarizes lessons learned.Methods: Participants (N = 612) were recruited from 7 Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) offices in Michigan and were individually randomized to an intervention n= 410) or a comparison (n =202) group (2: 1 ratio). During the 16-week intervention, intervention participants watched theory-based culturally sensitive videos (in DVD format) featuring peers from the target audience to learn skills for managing stress, eating healthier, and being more physically active. They also dialed into peer support group teleconferences to enhance skills learned in the videos and increase motivation for lifestyle behavioral changes. Body weight, the primary outcome, was measured at baseline, immediately after the 16-week intervention, and 3 months after the 16-week intervention. Intervention effect was tested via general linear mixed model for repeated measures, using baseline measures as adjusting covariates.Results: At baseline, the mean age of the participants was 28.5 ± 5.0 years (intervention: 28.4 ± 5.0, comparison: 28.9 ± 5.0); the mean body weight was 190.2 ± 1.4 lbs (intervention: 191.8 ± 30.0, comparison: 188.5 ± 29.1); and the mean body mass index (BMI) was 32.2 ± 4.4 (intervention: 32.2 ± 4.4, comparison: 31.7 ± 4.2). Of sample, 64.7% were obese. At 3 months after the 16-week intervention, no significant weight differences were found between the intervention (188.3 ± 10.6 lbs, BMI: 31.6 ± 1.8) and comparison groups (187.7 ± 10.6 lbs, BMI: 31.53 ± 1.8) when controlling for baseline body weight.Conclusions: This lifestyle behavioral intervention that focused on stress management, healthy eating and physical activity was not effective in helping low-income overweight and obese young mothers prevent further weight gain.Trial Registration: Clinical Trials NCT01839708 . This trial was registered retrospectively on February 28, 2013. [ABSTRACT FROM AUTHOR]

This secondary analysis study addressed a gap of knowledge: whether perceived stress reduction created by a lifestyle intervention might serve as a mediator for reducing fat and fast food intakes in low-income overweight or obese mothers of young children. This analysis included 338 low-income overweight or obese mothers of young children who completed a phone interview immediately after the 16-week lifestyle intervention. Valid surveys were used to assess perceived stress and fat and fast food intakes. Composite indicator structural equation modeling was performed to test the mediation effects. The overall effect of the intervention was not significant for fat intake but was significant for fast food intake (B = −0.53, p < 0.05). When assessing the potential role of perceived stress as a mediator, the indirect effects of the intervention on fat (B = −0.39, p < 0.01) and fast food (B = −0.27, p < 0.01) intakes were both significant. Future dietary intervention studies aimed to reduce fat and fast food intakes in low-income overweight or obese mothers of young children might consider including practical strategies aimed at reducing perceived stress.
