Objectives. We examined the impact of a prenatal exercise intervention on physical activity in 260 women at risk for gestational diabetes mellitus. Methods. We randomized participants in the Behaviors Affecting Baby and You (BABY) Study, which took place from 2007 to 2012, to either a 12-week individually tailored, motivationally matched exercise intervention (n = 132) or to a comparison health and wellness intervention (n = 128). We assessed physical activity with the Pregnancy Physical Activity Questionnaire. We used linear mixed models to evaluate the impact of the interventions on change in physical activity according to intensity and type, total walking, and sedentary behavior. Results. Compared with the health and wellness arm, the exercise arm had significantly greater increases in sports or exercise activity (0.3 vs 5.3 metabolic equivalent of task [MET] hours/week; P < .001), and smaller declines in total activity (–42.7 vs –2.1 MET hours/week; P = .02) and activities of moderate to vigorous intensity (–30.6 vs −10.6 MET hours/week; P = .05), and was more likely to achieve recommended guidelines for physical activity (odds ratio = 2.12; 95% confidence interval = 1.45, 3.10). Conclusions. These findings extend the previous literature by demonstrating the benefits of a clinically feasible exercise intervention in an ethnically and socio-economically diverse population. Given the increased risk of adverse maternal health outcomes in ethnic minority groups, these findings may have important implications for reducing health disparities.

“…Women diagnosed with GDM are at high risk for future diabetes, with approximately 50% of women developing type 2 diabetes within 5 years of delivery. It has been estimated that, in some populations, women with a history of GDM may account for up to one-third of diabetes cases among parous women 252. Women with GDM represent a heterogeneous group.…”

“…In one of the only trials to include a significant proportion of Hispanic women, the Behaviors Affecting Baby and You (B.A.B.Y) Study (clinical trial #NCT00728377) is an ongoing exercise trial among an ethnically diverse sample of prenatal care patients in Western Massachusetts at high risk of gestational diabetes mellitus (60 % Latina; [ 126 ]). Women are randomized to a 12-week motivationally targeted, individually tailored physical activity intervention involving multimodal contacts (in person, mail, and telephone) or to a comparison health and wellness intervention.…”

This chapter provides clinicians and researchers with an overview of the physical activity and pregnancy/postpartum literature to promote physical activity, understand the determinants and outcomes of physical activity participation among pregnant and postpartum women, recognize the scant literature pertaining to overweight and obese women, and inform next steps in practice, prevention, and research. We discuss (a) physical activity guidelines; (b) prevalence rates of physical activity during pregnancy and postpartum; (c) determinants, health outcomes, and critical gaps in the literature of pre-and postnatal physical activity; and (d) recommendations for research and practice to facilitate physical activity initiation, motivation, and maintenance across the transition to motherhood. Keywords Exercise • Recommendations • Pre-and postnatal periods • Health Key Points• Most pregnant and postpartum women fail to meet national guidelines for physical activity which may elevate their risk for morbidity and contribute to the intergenerational impact of obesity on their offspring.• Several key determinants of physical activity behavior in pregnancy and postpartum have been identified (e.g., education, income, social/emotional support, attitude/beliefs, environmental influences); however, these determinants are not well understood among overweight and obese women and therefore warrant future research attention.• Prenatal physical activity may reduce negative health outcomes such as gestational diabetes mellitus, preeclampsia, excessive gestational weight gain, and postpartum weight retention; however, currently there is no "gold standard" intervention for effectively promoting pre-and postnatal physical activity to consistently reduce these adverse outcomes across women of diverse socioeconomic and racial backgrounds.• Future attention in research and practice is needed to promote and disseminate the physical activity guidelines D.S. Downs et al. 185Statement of the ProblemThe majority of pregnant and postpartum women do not achieve the minimum physical activity recommendations from either the United States (US) government [ 1 ] or the American College of Obstetricians and Gynecologists (ACOG, later "College" became "Congress"); [ 2 ] this is of concern, given that physical activity during pregnancy is associated with improved weight control and maintenance of fitness as well as possible reduced risk of gestational diabetes and improved psychological functioning [ 2 -4 ]. Women who are active in postpartum tend to have less anxiety, depression, lactation-induced bone loss, and urinary stress incontinence, as well as improved cardiovascular fitness and psychological well-being [ 1 , 4 -6 ]. Physical Activity GuidelinesIn 1949, the US Children's Bureau issued a standard recommendation for prenatal Physical activity (PA): In the absence of maternal complications, pregnant women can continue housework, gardening, daily walks (up to 1 mile in several short bouts), and even swimming occasionally but should avoid sport...
