    Associations of the Neighborhood Built Environment with Gestational Weight Gain
    (Thieme, 2023) Grobman, William A.; Crenshaw, Emma G.; Marsh, Derek J.; McNeil, Rebecca B.; Pemberton, Victoria L.; Haas, David M.; Debbink, Michelle; Mercer, Brian M.; Parry, Samuel; Reddy, Uma; Saade, George; Simhan, Hyagriv; Mukhtar, Farhana; Wing, Deborah A.; Kershaw, Kiarri N.; NICHD nuMoM2b NHLBI nuMoM2b Heart Health Study Networks; Obstetrics and Gynecology, School of Medicine
    Objective: This study aimed to determine whether specific factors of the built environment related to physical activity and diet are associated with inadequate and excessive gestational weight gain (GWG). Study design: This analysis is based on data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be, a prospective cohort of nulliparous women who were followed from the beginning of their pregnancies through delivery. At each study visit, home addresses were recorded and geocoded. Locations were linked to several built-environment characteristics such as the census tract National Walkability Score (the 2010 Walkability Index) and the number of gyms, parks, and grocery stores within a 3-km radius of residential address. The primary outcome of GWG (calculated as the difference between prepregnancy weight and weight at delivery) was categorized as inadequate, appropriate, or excessive based on weight gained per week of gestation. Multinomial regression (generalized logit) models evaluated the relationship between each factor in the built environment and excessive or inadequate GWG. Results: Of the 8,182 women in the analytic sample, 5,819 (71.1%) had excessive GWG, 1,426 (17.4%) had appropriate GWG, and 937 (11.5%) had inadequate GWG. For the majority of variables examined, built environments more conducive to physical activity and healthful food availability were associated with a lower odds of excessive or inadequate GWG category. For example, a higher number of gyms or parks within 3 km of a participant's residential address was associated with lower odds of having excessive (gyms: adjusted odds ratio [aOR] = 0.93 [0.89-0.96], parks: 0.94 [0.90-0.98]) or inadequate GWG (gyms: 0.91 [0.86-0.96]; parks: 0.91 [0.86-0.97]). Similarly, a higher number of grocery stores was associated with lower odds of having excessive GWG (0.94 [0.91-0.97]). Conclusion: Among a diverse population of nulliparous women, multiple aspects of the built environment are associated with excessive and inadequate GWG.

    Associations of the Neighborhood Built Environment With Physical Activity Across Pregnancy
    (Human Kinetics, 2021-04-15) Kershaw, Kiarri N.; Marsh, Derek J.; Crenshaw, Emma G.; McNeil, Rebecca B.; Pemberton, Victoria L.; Cordon, Sabrina A.; Haas, David M.; Debbink, Michelle P.; Mercer, Brian M.; Parry, Samuel; Reddy, Uma; Saade, George; Simhan, Hyagriv; Wapner, Ronald J.; Wing, Deborah A.; Grobman, William A.; NICHD nuMoM2b Heart Health Study Network; NHLBI nuMoM2b Heart Health Study Network; Obstetrics and Gynecology, School of Medicine
    Background: Several features of the neighborhood built environment have been shown to promote leisure-time physical activity (PA) in the general population, but few studies have examined its impact on PA during pregnancy. Methods: Data were extracted from 8362 Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be cohort participants (2010-2013). Residential address information was linked to 3 built environment characteristics: number of gyms and recreation areas within a 3-km radius of residence and census block level walkability. Self-reported leisure-time PA was measured in each trimester and dichotomized as meeting PA guidelines or not. Relative risks for cross-sectional associations between neighborhood characteristics and meeting PA guidelines were estimated using Poisson regression. Results: More gyms and recreation areas were each associated with a greater chance of meeting PA guidelines in models adjusted for sociodemographic characteristics and preexisting conditions. Associations were strongest in the third trimester where each doubling in counts of gyms and recreation areas was associated with 10% (95% confidence interval, 1.07-1.13) and 8% (95% confidence interval, 1.03-1.12), respectively, greater likelihood of meeting PA guidelines. Associations were similar though weaker for walkability. Conclusions: Results from a large, multisite cohort suggest that these built environment characteristics have similar PA-promoting benefits in pregnant women as seen in more general populations.
