More and more women in the United States are choosing to delay mother-hood until their 30s or even 40s. Yet traditional medical advice warns against midlife pregnancy, predicting a variety of adverse reproductive outcomes associated with "advanced maternal age." Assignment to a high-risk category may result in heightened feelings of concern about pregnancy complications among midlife mothers. Because it is possible that increased emotionality during pregnancy may itself give rise to various childbearing complications, some middle-aged women may become victims of iatrogenic stress during pregnancy. This article first examines critically the medical literature describing the relationship between maternal age and pregnancy outcomes and finds little support for the medical pessimism. Next, the article describes the literature that explores the links between heightened emotionality during pregnancy and various negative outcomes and suggests that, despite serious methodological flaws, there is some evidence that fear-induced stress during pregnancy may place certain middle-aged women at higher risk for complications. Finally, strategies for improved decisionmaking and for enhancing the pregnancy experience of midlife women are proposed. 相似文献

Latent growth mixture modeling was used to identify developmental trajectories (described in terms of demographics, exposure and resistance to a pro-drug environment, and deviant behavior) of binge drinking among 5,694 individuals who completed 6 surveys from ages 13 to 23 years: nonbingers (32%); moderate stables (37%), who had consistently low levels of bingeing; steady increasers (16%), who increased from the lowest to highest level of bingeing; adolescent bingers (9%), whose early rise in bingeing was followed by a decrease to a moderate level; and early highs (6%), who decreased from the highest level of bingeing to a moderate level. Results show considerable diversity in binge drinking patterns and the correlates of bingeing across trajectory classes. 相似文献
