“…Contextual and social exposures shared among individuals within communities may predict the formation of maternal mental health clusters, emphasizing the importance of examining community-level risks. Community-level contextual variables considered were: racial residential segregation ( Anthopolos et al, 2011 , 2014 ; Salow et al, 2018 ; Moore, 2017 ; Upadhyaya et al, 2014 ; Weil, 2021 ), economic residential segregation ( Nager et al, 2006 ; Moore, 2017 ), access to greenspace ( Sun et al, 2023 ; Kihal-Talantikite et al, 2013 ; Runkle et al, 2022 ; Feng and Astell-Burt, 2018 ), and rural vs. urban residence ( Craemer et al, 2023 ; Ginja et al, 2020 ; Mollard et al, 2016 ; Ross et al, 2011 ). These variables were considered at the zip code tabulation area (ZCTA) level, which is the smallest spatial unit resolution available for this dataset.…”
