Objectives. Puerperal psychosis was studied in black African women at Barag
wanath Hospital in Johannesburg.
Design. A retrospective study analysed the clinical notes of 314 cases of p
uerperal psychosis seen over previous years. A prospective study researched
67 cases of puerperal psychosis referred during a full calendar year. A co
ntrol group of 98 patients was matched with the prospective study patients
for age, marital status, parity and month of delivery.
Results. The incidence (2 - 3 cases per 1 000 births), onset and pattern of
illness are all remarkably similar to that described in the international
literature. Confirmed risk factors were a primiparous patient; a family his
tory of psychiatric illness; and a personal psychiatric history, particular
ly a history of mania. Additional risk factors found in this study were sub
stance dependence; a medical illness; the season of the year; a male child;
and psychosocial stress including need for intensive medical care for the
baby or death of the baby.
Conclusion. The conclusion reached is that the puerperal psychoses are undi
fferentiated psychoses, usually mood disorders, showing some special sympto
matology, and are precipitated in constitutionally predisposed patients by
the physiological factors of the involutionary period.
