大量证据表明，产前母亲压力（PNMS）对出生结果有不利影响，包括出生体重和分娩时的妊娠猿。作者假设，PNMS 的影响部分归因于悲观主义等性格，这些性格导致女性认为自己的生活充满压力，并且 PNMS 的影响和性格对出生结果的影响是由产前健康行为介导的。作者使用结构方程建模程序，在控制风险和种族的影响的情况下，研究了 PNMS 和性格乐观对医学高风险样本 (N = 129) 的出生体重和胎龄的前瞻性影响。在考虑到 PNMS 与乐观情绪的强烈负相关关系后，PNMS 对出生结果没有影响。在控制胎龄的情况下，最不乐观的女性生下的婴儿体重明显减轻。乐观者更有可能锻炼身体，而锻炼与较低的早产风险相关。结果表明，怀孕期间的慢性压力可能反映了导致不良分娩结果的潜在倾向。
A sizable body of evidence indicates that prenatal maternal stress (PNMS) has an adverse impact on birth outcomes, including birth weight and gestational ape at delivery. The authors hypothesized that effects of PNMS are attributable in part to dispositions such as pessimism that lead women to view their lives as stressful and that effects of PNMS and disposition on birth outcome are mediated by prenatal health behaviors. Using structural equations modeling procedures, the authors examined prospective impact of PNMS and dispositional optimism on birth weight and gestational age in a medically high-risk sample (N = 129), controlling for effects of risk and ethnicity. After its strong inverse association with optimism was accounted for, PNMS had no impact on birth outcomes. Women who were least optimistic delivered infants who weighed significantly less, controlling for gestational age. Optimists were more likely to exercise, and exercise was associated with lower risk of preterm delivery. Results suggest that chronic stress in pregnancy may be a reflection of underlying dispositions that contribute to adverse birth outcomes.
