FIGURE 1—

Mean predicted birth weight by stressful life events prior to conception (PSLEs): US Early Childhood Longitudinal Study, Birth Cohort, 2001.

Note. The solid line represents the relationship between mean predicted birth weight as a function of PSLEs. The dashed lines represent the 95% confidence interval (CI) for the mean predicted birth weight; calculated standard errors of the prediction were used to generate the CIs. The inset table displays the mean values and 95% CIs for each point, in addition to the difference in means (i.e., mean reduction) compared with the mean for women with no PSLEs; analysis of variance was performed to generate the mean reduction and 95% CIs for predicted birth weight. Each mean is statistically significantly different from all other means at P < .01.
