Fit Moms in Partners, Children, and Other Members
Lifestyle interventions targeting overweight/obese individuals can produce positive "ripple" effects on untreated overweight partners in the home. Interestingly, ripple effects on partners' weight appear most pronounced when the interventions target women. Women, and mothers in particular, remain the primary "nutritional gatekeepers" of the home. Despite widespread recognition that motherhood is a powerful motivator for behavior changes, no study to date has examined the "ripple" effects of a postpartum Internet-based lifestyle intervention that target mothers' weight. The purpose of this ancillary study is to determine whether a behavioral weight loss intervention for postpartum mothers (5R01DK087889-02, PI Phelan; Co-I Tate) has a positive "ripple" effect on weight and health of partners and children/offspring. The proposed study is ancillary to an ongoing clinic-randomized trial examining the efficacy of an innovative multicomponent (online, face-to-face, mobile phone) postpartum behavioral weight loss intervention in 408 low-income women in the Women, Infants, and Children program. The proposed study will determine whether partners of women randomized to the postpartum BWL intervention have greater weight losses and greater improvements in health outcomes than partners of women in standard WIC. Similar to the parent grant, assessments will occur at study entry, 6 months, and 12 months. This project is highly innovative, as it capitalizes on existing funded research and is the first study to examine ripple effects of multicomponent Internet-based intervention in low-income individuals. The project also has high impact, as the postpartum period is a powerful motivator for behavior and environmental changes in the home; and, if positive ripple effects occur, the field of obesity treatment and prevention could move beyond focus on individual level to the often, unrecognized interpersonal effects of lifestyle interventions. PUBLIC HEALTH RELEVANCE: This research project will examine whether a postpartum weight-loss intervention has a positive "ripple" effects on weight and health of untreated partners and offspring/children in the home.

Time Perspective: Prospective
|Official Title:||Effects of Postpartum Weight Loss Intervention on Partner and Offspring Weight|
- Weight and Weight Change [ Time Frame: 12 months ] [ Designated as safety issue: No ]Absolute weight and change in weight will be measured to the nearest 0.1 kg using a calibrated and portable standard digital scale
- Change from baseline in mood [ Time Frame: 12 months ] [ Designated as safety issue: No ]The Beck Depression Inventory-II will be used to examine change from baseline levels of mood and depressive symptoms
- Change from Baseline in Physical Activity Levels [ Time Frame: 12 months ] [ Designated as safety issue: No ]Change from Baseline in Physical Activity Levels will be assessed using the Actigraph accelerometer.
- Change from Baseline in Dietary Intake [ Time Frame: 12 months ] [ Designated as safety issue: No ]Change from Baseline in Dietary Intake will be assessed using 24-hour recalls.
- Change from baseline in Dietary Restraint [ Time Frame: 12 months ] [ Designated as safety issue: No ]Change from baseline in dietary restraint will be assessed by the Eating Inventory questionnaire
- Change from baseline in self-efficacy [ Time Frame: 12 ] [ Designated as safety issue: No ]Change from baseline in self-efficacy will be assessed using Weight Efficacy Lifestyle Questionnaire.
- Change from baseline in stress [ Time Frame: 12 ] [ Designated as safety issue: No ]Change from baseline in stress will be assessed using the short-form of the Perceived Stress Scale.
- Change from baseline in sleep [ Time Frame: 12 months ] [ Designated as safety issue: No ]Change from baseline in sleep will be assessed by the general sleep disturbance questionnaire
- Change from baseline in partner connectedness [ Time Frame: 12 months ] [ Designated as safety issue: No ]Partners will be asked to complete a questionnaire adapted from Look AHEAD, which assesses frequency of grocery shopping by self and members in the home, number of meals shared with postpartum partner and others in the home, and whether the meal is eaten inside and outside the home, and frequency of cooking (in reference to self and others in the home).
- Change from baseline in relationship status [ Time Frame: 12 months ] [ Designated as safety issue: No ]The Dyadic Adjustment Scale will be used to assess change from baseline in relationship stability, intimacy and history.
