  Purpose

Lifestyle interventions targeting overweight 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 prenatal lifestyle interventions that target mothers' gestational weight gain. The primary aim of the proposed study is to determine whether lifestyle interventions to prevent excessive gestational weight gain in overweight/obese pregnant women have positive "ripple" effects on untreated partners in the home. The proposed study is ancillary to two randomized phase III clinical trials in the LIFE-moms consortium (1U01HL114377-01, PI Phelan; 3U01DK094418-01S1, PIs Martin and Redman) that are examining the efficacy of multi-component lifestyle interventions to prevent excessive gestational weight gain in a total of 650 overweight/obese women. In this ancillary study, partners' weight, home environment, and psychosocial behaviors will be assessed when their pregnant partners are ~13 weeks gestation (study entry), 35 weeks gestation and at 6 and 12 months postpartum. We hypothesize that partners of pregnant women randomized to the lifestyle intervention, relative to those of standard care, will have greater weight losses through 12-months. Secondary aims examine partner improvements in weight control behaviors, the home environment, and psychosocial parameters. This project is highly innovative, as it capitalizes on existing funded research and is the first study to examine ripple effects of multicomponent prenatal interventions. The project also has high impact, as pregnancy 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 interventions to prevent excessive gestational weight gain have positive "ripple" effects on the health of untreated partners in the home.

Primary Outcome Measures:
  • Change in weight of partners of pregnant women [ Time Frame: 13 weeks gestation, 35 weeks gestation, 6 months and 12 months postpartum ] [ Designated as safety issue: No ]
    Change in weight of partners of pregnant women randomized to the lifestyle intervention, relative to partners of pregnant women of standard care, from 13 weeks gestation to 35 weeks gestation and 6 and 12-months postpartum.


Secondary Outcome Measures:
  • Percent of partners with weight change loss >5%, 10%, and 15% [ Time Frame: 13 weeks gestation, 35 weeks gestation, 6 months and 12 months postpartum ] [ Designated as safety issue: No ]
  • Change in calorie and fat intake [ Time Frame: 13 weeks gestation, 35 weeks gestation, 6 months and 12 months postpartum ] [ Designated as safety issue: No ]
  • Change in physical activity levels [ Time Frame: 13 weeks gestation, 35 weeks gestation, 6 months and 12 months postpartum ] [ Designated as safety issue: No ]
  • Change in sleep patterns and sleep hours [ Time Frame: 13 weeks gestation, 35 weeks gestation, 6 months and 12 months postpartum ] [ Designated as safety issue: No ]
  • Change in self-monitoring [ Time Frame: 13 weeks gestation, 35 weeks gestation, 6 months and 12 months postpartum ] [ Designated as safety issue: No ]
  • Change in food, exercise and sedentary cues in the home environment [ Time Frame: 13 weeks gestation, 35 weeks gestation, 6 months and 12 months postpartum ] [ Designated as safety issue: No ]
  • Change in mood [ Time Frame: 13 weeks gestation, 35 weeks gestation, 6 months and 12 months postpartum ] [ Designated as safety issue: No ]
  • Change in dietary restraint [ Time Frame: 13 weeks gestation, 35 weeks gestation, 6 months and 12 months postpartum ] [ Designated as safety issue: No ]

Groups/Cohorts
Partners of intervention pregnant women
Partners of pregnant women randomized to lifestyle intervention. Note: There is no intervention in partners of pregnant women.
Partners of no intervention pregnant women
Partners of pregnant women randomized to Standard Care. Note: There is no intervention in partners of pregnant women.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population

This study uses a randomized repeated measures design. Partners will be categorized based on randomized status of their pregnant partner (in the parent grants; NIH 1U01HL114377-01, PI Phelan; NIH 3U01DK094418-01S1, PIs Redman and Martin). Partner participation in the ancillary study will not be mandatory for participation in the parent grant. NOTE: There is no intervention in partners.

Criteria

Inclusion Criteria:

  • Man or woman who self-identifies as sharing an intimate relationship and cohabitating in the home with the pregnant women (enrolled in the parent grant) for the previous 3 months or recently been married and living in the home
  • ≥18 years
  • willing to provide informed consent/assent

Exclusion Criteria:

  • None
