Incidence of postpartum abuse in women with a history of abuse during pregnancy.
OBJECTIVE
To determine whether women with a history of physical abuse during pregnancy have an increased incidence of physical abuse in the 3 months after delivery.


METHODS
Follow-up survey.


METHODS
A primary care community-based prenatal clinic, private obstetricians' and family physicians' offices in a large city, family physicians' offices in a small town and a tertiary care university teaching hospital.


METHODS
Thirty-six women identified in a study of physical abuse during pregnancy; 30 (83.3%) agreed to participate.


METHODS
Number of incidents of physical abuse during the 3 months before conception, during the first, second and third trimesters of pregnancy and during the 3 months after delivery. General Health Questionnaire (GHQ) score to determine psychologic distress and predict psychiatric morbidity. Interview to diagnose psychiatric disorders according to defined criteria.


RESULTS
Twenty-seven (90.0%) of the 30 participants reported a total of 57 incidents of abuse in the 3 months after delivery. For each period, the mean number of incidents of abuse per woman abused in that period was calculated and was found to be significantly higher for the postpartum period (2.1) than for the 3 months before conception (1.5) or for the first, second or third trimesters (1.4, 1.3 and 1.1) (F = 18.87, p < 0.001, one-way repeated measures analysis of variance.) This finding was confirmed by the Newman-Keuls post-hoc test, which also showed that the means for the preconception period and the three trimesters did not differ significantly between themselves. Nineteen (95%) of the 20 women who were abused in the first trimester were abused in the 3 months after delivery. Fourteen women (51.9%) obtained medical care for injuries from the postpartum abuse. The mean GHQ score was 7.7 (a score of 3 or more suggests psychiatric morbidity); from the psychiatric interview, 16 women (53.3%) were found to meet the diagnostic criteria for a major depressive episode, 9 (30.0%) had another psychiatric disorder, and 5 (16.7%) had no psychiatric disorder.


CONCLUSIONS
A significant increase was found in the mean number of incidents of physical abuse per woman abused during the 3 months after delivery over the mean number of incidents per woman abused during each of the three other periods. Physicians should be alert to physical abuse in postpartum women and should make specific enquiries if there is a history of abuse, current injury or depression.
