Post-traumatic stress symptoms in mothers of very low birth weight infants 2-3 years post-partum.

We examined symptoms of post-traumatic stress disorder (PTSD) in mothers of very low birth weight (VLBW) infants 2-3 years post-partum, compared with mothers of term, normal weight infants. Mothers were asked to report current symptoms relating specifically to the birth of their infant using The Impact of Event Scale-Revised (IES-R). Mothers of VLBW infants recorded significantly higher levels of PTSD symptoms overall (median scores: VLBW 25 [range 2-82], versus controls: 0 [range 0-5], P < 0.001), and in all sub-categories (p < 0.001). These findings suggest that mothers of VLBW infants have a relatively high prevalence of symptoms of PTSD at 2-3 years postnatal.
