ObjectiveTo describe differences in four high risk periconceptional behaviors (lack of folic acid supplementation, lack of early prenatal care, smoking, and drinking) by maternal occupation.MethodsAnalyses were conducted among women in the National Birth Defects Prevention Study who delivered liveborn infants without birth defects. Periconceptional occupational data were collected using a computer-assisted telephone interview and occupational coding was performed using the 2000 Standard Occupational Classification System. Logistic regression analyses were conducted to determine whether prevalence of behaviors differed between occupational groups.ResultsSubjects included 5153 women employed during early pregnancy from 1997 to 2007. Compared to women in management, business, science, and arts occupations, women in other occupations (e.g., service occupations) were significantly more likely to engage in all four high risk behaviors. Specifically, women in food preparation/serving-related occupations were significantly more likely to engage in all four behaviors compared to women in all other occupational groups (odds ratios: 1.8-3.0), while women in education/training/library occupations were significantly less likely to do so (odds ratios: 0.2-0.5).ConclusionWe identified several occupational groups with an increased prevalence of high-risk maternal behaviors during pregnancy. Our findings could aid in developing interventions targeted towards women in these occupational groups.Copyright © 2012 Elsevier Inc. All rights reserved.
