Brief Summary

Women with pre-pregnancy obesity, women who exceed recommended weight gain during pregnancy, and children who experience rapid and excess growth during the first year of life are all at risk for subsequent obesity. The purpose of this study is to examine creative cognitive strategies to promote healthy weight gain during pregnancy, creating a sound substrate of metabolic programming for the critical first six months of life. A trans-disciplinary approach utilizing a patient- and family-centered intervention and active patient engagement with counseling for positive gain will work with women to shape lifestyle during pregnancy and postpartum, and when feeding their infants in the first 6 months of life. It is hypothesized patient engagement with counseling for positive gains will successfully mitigate excess weight gain in both pregnancy and infancy compared to usual care. Moreover, data will be examined to assess whether psychological variables, work and school climate, and social support factors influence body weight gain trajectories and/or weight loss during and after pregnancy.

Detailed Description

Obesity is increasingly common among reproductive aged women and women presenting for their first pregnancy. Women with overweight and obesity are more likely to exceed recommended weight gain during pregnancy and retain excess weight after delivery. Women with pre-pregnancy obesity, women who exceed recommended weight gain during pregnancy, and children who experience rapid and excess growth during the first year of life are all at risk for subsequent obesity. Additionally, maternal obesity is a significant risk factor for pregnancy complications (i.e., hypertensive disorders of pregnancy, gestational diabetes) and is associated with adverse pregnancy outcomes, including excess fetal weight at birth. The goal of this study is to test the effectiveness of active patient engagement with counseling for positive gain to mitigate excess weight gain in women during pregnancy and postpartum, and in the first six months of life. Pregnant women eligible to receive care in the Military Health System (MHS) will be randomized to receive either the positive-gain counseling (PGC) prevention program or usual care (UC). PGC is designed to empower women to examine food choices and activity patterns during pregnancy to help them adhere to the Institute of Medicine (IOM) recommended weight gain standards. PGC patients will be paired with counselors who follow their pregnancy from start to finish, as well as providing neonatal and infant support in a continuous fashion as part of team-based care. Women in the usual care (UC) group will receive prenatal care in accordance with the VA/DoD Guideline for the Management of Pregnancy. Both groups will receive routine well-child care in accordance with established guidelines from the American Academy of Pediatrics and the American Academy of Family Physicians. Routine well-child care appointments (UC) take place at 2-3 days after birth, 2 weeks of life, 2 months of life, 4 months, 6 months, 9 months and 12 months. Participants' weight status, food intake, and mood will be assessed once during each trimester and at 2 weeks, 2 months, 4 months, and 6 months postpartum. Individuals enrolled in the PGC group will receive specific counseling once during each trimester and at 2 weeks, 2 months, 4 months and 6 months postpartum. Well-child sessions will focus on positive-gain-based cognitive strategies to promote breastfeeding, recognition of satiety cues and other healthy food choices. It is hypothesized that participants who receive the positive-gains counseling program will show significantly less weight gain in both pregnancy and infancy relative to those randomized to usual care.

Study Groups

Positive-Gain Counseling (PGC)

Positive-gain-based health promotion interventions capitalize on the basic human desire to maintain consistency between one's words and actions for beneficial outcomes. Participants will discuss potential costs of unhealthy behaviors and the benefits of healthier lifestyle choices, and how they apply not only to adults, but also to developing children. Theoretically, discussing these perspectives will make the mothers more likely to make healthier lifestyle choices in the future.

Group Type: EXPERIMENTAL

Positive-Gain Counseling (PGC)

Intervention Type: BEHAVIORAL

Positive-gain-based health promotion interventions capitalize on the basic human desire to maintain consistency between one's words and actions for beneficial outcomes. Participants will be asked to discuss potential adverse effects of obesity, an unhealthy diet, and sedentary behavior, as well as the benefits of maintaining a physically fit body, eating a healthy diet, and regular physical activity. They will also discuss the costs and benefits as they apply to developing children. Theoretically, discussing and reviewing these perspectives will make the mothers more apt to make healthier lifestyle choices in the future. Women randomized to the positive-gains counseling (PGC) group will have PGC sessions once during each trimester and at 2 weeks, 2 months, 4 months and 6 months postpartum. PGC participants will also receive prenatal care in accordance with the VA/DoD Guideline for the Management of Pregnancy.

Usual Care (UC)

UC includes regular clinic visits, routine blood and urine screening tests, and anticipatory guidance from a primary care provider in accordance with the VA/DoD Guideline for the Management of Pregnancy. After delivery, participants receive routine well-child care in accordance with established guidelines from the American Academy of Pediatrics and the American Academy of Family Physicians.

Group Type: ACTIVE_COMPARATOR

Usual Care

Intervention Type: OTHER

Women in the usual care (UC) group will receive prenatal care in accordance with the VA/DoD Guideline for the Management of Pregnancy. This entails regular clinic visits, routine blood and urine screening tests, and anticipatory guidance. Routine well-child care appointments will take place at 2-3 days, 2 weeks, 2 months, 4 months, 6 months, 9 months and 12 months after birth. During routine well-child visits, height, weight, and vital signs are measured, developmental milestones are reviewed, and a thorough physical examination is performed. Age-appropriate immunizations are provided as is parental anticipatory guidance, including the importance of breastfeeding. Participants enrolled in the UC group will receive anticipatory guidance from their primary care provider in the usual fashion. Providers will deliver this anticipatory guidance with no external cues or counseling provided by the research team.
