I find that in utero exposure to MPDOs increases the likelihood of being diagnosed with newborn disorders related to adverse birth outcomes by 13%. Women exposed to MPDOs during pregnancy\u2014particularly in the first and second trimesters\u2014experience delays in critical prenatal care, such as ultrasounds and the detection of gestational health conditions. These disruptions likely contribute to the observed increase in adverse birth outcomes. The findings highlight the intergenerational and long\u2010term consequences of interrupted maternal care.<\/jats:p>","DOI":"10.1002\/hec.70060","type":"journal-article","created":{"date-parts":[[2025,12,5]],"date-time":"2025-12-05T08:00:12Z","timestamp":1764921612000},"page":"455-494","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Pandemic Babies: Medical Care Delays in Utero and Infant Birth Outcomes"],"prefix":"10.1002","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8649-0914","authenticated-orcid":false,"given":"Xuechao","family":"Qian","sequence":"first","affiliation":[{"name":"Department of Economics Ball State University  Muncie Indiana USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,5]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"crossref","unstructured":"Acemoglu D.
