Confinement and other psychosocial factors in perinatal depression: a transcultural study in Singapore

To investigate the prevalence, socio-cultural and psychosocial risk factors for perinatal depression in Singaporean women.

A prospective cohort of 559 women was interviewed antenatally and at six weeks' postpartum at a tertiary hospital. Women were interviewed for diagnosis of depression using a two-stage design, with a screening questionnaire and diagnostic interview.

Postnatally, a negative confinement experience was associated with depression. Other independent factors included poor emotional support, a past history of depression, unplanned pregnancy and perceived potential conflicts with relatives over childcare antenatally and dissatisfaction, poor instrumental support postnatally. The prevalence of depression antenatally and postnatally was 12.2% and 6.8%, respectively.

Measures of satisfaction with social support were based on self-report; there were high dropout rates at six weeks' postpartum; and other modulating social factors such as pre-existing interpersonal conflicts were not studied.

Perinatal depression in Singaporean women is common. Contrary to expectations, a negative 'confinement' experience is a significant risk factor for postnatal depression, and is not universally welcomed by women. Depression is modulated by dissimilar sets of psychosocial factors antenatally and postnatally.
