Implications for research of environmental exposure in the course of pregnancy are discussed.N for P5 the discriminant analyses revealed that only 4.7 of the NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptJ Expo Sci Environ Epidemiol. We recorded, exactly where doable, the process made use of to assess residential histories also because the times within pregnancy for which residences have been recorded (e.g., addresses at conception and birth versus complete residential history with occasions and locations for all moves). Outcomes had been summarized with respect to overall mobility rates and distance moved. We evaluated results with regards to how the probability of moving during pregnancy varied by demographic components which include mother's age, marital status, and SES; smoking and alcohol use through pregnancy; timing in pregnancy; urbanicity; as well as other elements. We also reviewed outcomes from studies that assessed how residential mobility impacts estimates of exposure to environmental situations. A meaningful quantitative mixture of final results, like meta-analysis, was not feasible simply because of variation in study styles.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author Manuscript RESULTSStudies on.Al variation.20 For studies assessing exposure primarily based around the residence at per.1944 delivery, when the probability of moving differs by timing in pregnancy, exposures by trimester might be differentially impacted, with larger misclassification in the 1st trimester compared using the third trimester. Residential mobility has been studied within a assortment of settings which includes the general adult US population,21 persons with mental illness,22 youngsters with leukemia,23 and young children generally.24 Because the probability of moving probably differs for pregnant versus non-pregnant ladies, basic population studies may not be applicable. Research on moves by couples in the Netherlands identified that persons have been much more likely to move a short distance (j.addbeh.2012.ten.012 (SES). As an example, a study of changes in residence for a mentally ill cohort located links in between mobility and numerous elements like substance abuse and marital status.22 A limited number of studies examined residential mobility of pregnant women. Right here we overview these research and synthesize their evidence with respect for the frequency, distance, and timing of moves for the duration of pregnancy. We summarize findings with regards to the relationship between mobility and population qualities. Implications for studies of environmental exposure for the duration of pregnancy are discussed.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptJ Expo Sci Environ Epidemiol. Author manuscript; offered in PMC 2013 January 11.Bell and BelangerPageMATERIALS AND METHODSWe identified study on residential mobility through pregnancy applying a healthcare literature database, PubMed, and an academic literature database, Scopus, for research indexed by way of August 2011. Searches were conducted for articles with every single of the following within the title and/or abstract: (1) "pregnancy," "pregnant," "prenatal," or "maternal;" (two) "mobility;" and (3) "residence," "residences," or "residential." Articles were restricted to those published in English. Only peer-reviewed study was included. We also examined references of identified articles as a supply of more studies. Essential features of every single study were identified like: location and time period, data sources, number of study subjects, as well as the nature of population (e.g., pregnant ladies within the basic population or cases from a case-control study).
