It is not understood whether subtle facial characteristics occur in children without a diagnosis but who were exposed to a range of common pregnancy drinking patterns and, if so, whether these persist throughout childhood.<\/jats:p><\/jats:sec>Objective<\/jats:title>To determine whether subtle changes in facial shape with prenatal alcohol exposure found in 12-month-old children were evident at age 6 to 8 years using extended phenotyping methods and, if so, whether facial characteristics were similar to those seen in fetal alcohol spectrum disorder.<\/jats:p><\/jats:sec>Design, Setting, and Participants<\/jats:title>In a prospective cohort study in Melbourne, Victoria, Australia, commencing in July 2011 with follow-up through April 2021, pregnant women were recruited in the first trimester from low-risk, metropolitan, public maternity clinics over a period of 12 months. Three-dimensional craniofacial images from 549 children of European descent taken at age 12 months (n\u2009=\u2009421 images) and 6 to 8 years (n\u2009=\u2009363) were included. Data analysis was performed from May 2021 to October 2024.<\/jats:p><\/jats:sec>Exposures<\/jats:title>Predominantly low to moderate prenatal alcohol exposure in the first trimester or throughout pregnancy compared with controls without prenatal alcohol exposure.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>Following hierarchical facial segmentation, phenotype descriptors were computed. Hypothesis testing was performed for 63 facial modules to analyze different facial parts independently using principal component analysis and response-based imputed predictor (RIP) scores. Comparison was made with a clinical discovery sample of facial images of children with a confirmed diagnosis of partial or full fetal alcohol syndrome.<\/jats:p><\/jats:sec>Results<\/jats:title>A total of 549 children took part in the 3-dimensional craniofacial image analysis, of whom 235 (42.8%) contributed an image at both time points. Time 1 included 421 children, comprising 336 children (159 [47.3%] female) with any prenatal alcohol exposure and 85 control children (45 [52.9%] female); time 2 included 363 children, comprising 260 children with any prenatal alcohol exposure (125 [48.1%] female; mean [SD] age, 6.9 [0.7] years) and 103 control children (53 [51.5%] female; mean [SD] age, 6.8 [0.7] years). At both time points, there was consistent evidence for an association between prenatal alcohol exposure and the shape of the eyes (eg, module 15: RIP partial Spearman \u03c1, 0.19 [95% CI, 0.10-0.29; P<\/jats:italic>\u2009&amp;lt;\u2009.001] at 6-8 years) and nose (eg, module 5: RIP partial Spearman \u03c1, 0.19 [95% CI, 0.09-0.27; P<\/jats:italic>\u2009&amp;lt;\u2009.001] at 6-8 years), whether exposure occurred only in trimester 1 or throughout pregnancy. Facial variations observed differed from those in the clinical discovery sample.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>Low to moderate prenatal alcohol exposure was associated with characteristic changes in the face, which persisted until at least 6 to 8 years of age. A linear association between alcohol exposure levels and facial shape was not supported.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamapediatrics.2024.6151","type":"journal-article","created":{"date-parts":[[2025,2,10]],"date-time":"2025-02-10T16:01:09Z","timestamp":1739203269000},"page":"438","source":"Crossref","is-referenced-by-count":10,"title":["Low
