Clinical and Obstetric Risk Factors for Postnatal Depression in HIV Positive Women: A Cross Sectional Study in Health Facilities in Rural KwaZulu-Natal.

Postnatal depression (PND) remains underdiagnosed and undertreated in different socio-economic backgrounds in South Africa. This study determined the prevalence of and clinical and obstetric risk factors for PND symptoms among HIV positive women in health facilities in a rural health district in South Africa. The Edinburgh Postnatal Depression Scale was used to measure PND from 386 women who had delivered a live infant. More than half (58.5%) tested HIV positive during the current pregnancy. The prevalence of PND symptoms was 42.5%. Logistic regression analysis yielded significant associations between clinical and obstetric variables of pre-term baby (p-value < 0.01), baby health status p-value < 0.01), baby hospitalization, (p-value < 0.01), and knowing the baby's HIV status (p-value = 0.047). Maternal variables associated with PND were level of education (p-value < 0.01), monthly income (p-value < 0.01), and source of income (p-value = 0.05). At multivariate analysis, none of the clinical and obstetrical risk factors were independently associated with the PND. The high prevalence of PND symptoms underscore the need to integrate routine screening for PND in prevention of mother to child transmission of HIV programmes to enable early diagnosing and treatment of PND.
