to determine whether there is an independent association between physical abuse during pregnancy or stress because of emotional, sexual, or physical abuse during pregnancy and birthweight after adjusting for behavioral, psychosocial, demographic, and medical variables.
We conducted a cross sectional study of 808 low-income women, age 18 years or older, who delivered single infants from pregnancies of 20 weeks or longer. Abuse during the current pregnancy was measured as reported events of physical abuse and stress because of emotional, sexual, or physical abuse. Multiple regression models were developed to estimate the association of low birthweight (LBW) and mean birthweight with abuse during pregnancy, adjusting for behavioral, psychosocial, demographic, and medical variables.
Physical abuse during pregnancy was not associated with LBW or with mean birthweight. Women who reported stress because of abuse had 2.1 times higher odds of LBW (95% CI 1.2, 3.6) than those who did not, and the mean birthweight of their infants was 236 g lower (95% CI -371, -102) than those of women who reported no stress because of abuse in the adjusted regression models. Furthermore, the adjusted mean birthweight for LBW infants of women reporting stress because of abuse was significantly lower (-372, 95% CI 595, -149) than for LBW infants of women reporting no stress.
Stress because of abuse during pregnancy was associated with both LBW and lower mean birthweight after adjusting for behavioral, psychosocial, demographic, and medical variables.
在对行为、心理社会、人口统计学和医学变量进行校正后，确定孕期身体虐待或孕期因情感、性或身体虐待所致压力与出生体重之间是否存在独立关联。
我们对808名年龄在18岁及以上的低收入妇女进行了一项横断面研究，这些妇女分娩的是孕周为20周或更长时间的单胎婴儿。当前孕期的虐待情况通过报告的身体虐待事件以及因情感、性或身体虐待所致压力来衡量。我们建立了多元回归模型，以估计低出生体重（LBW）和平均出生体重与孕期虐待之间的关联，并对行为、心理社会、人口统计学和医学变量进行校正。
孕期身体虐待与低出生体重或平均出生体重无关。报告因虐待而感到压力的妇女出现低出生体重的几率比未报告者高2.1倍（95%可信区间1.2, 3.6），且在经校正的回归模型中，其婴儿的平均出生体重比未报告因虐待而感到压力的妇女的婴儿低236克（95%可信区间 -371, -102）。此外，报告因虐待而感到压力的妇女所生低出生体重婴儿的校正平均出生体重显著低于未报告压力的妇女所生低出生体重婴儿（-372, 95%可信区间 -595, -149）。
在对行为、心理社会、人口统计学和医学变量进行校正后，孕期因虐待所致压力与低出生体重和较低的平均出生体重均有关联。
