Depression among pregnant women testing for HIV in rural South Africa

[摘要] ENGLISH ABSTRACT: Pregnancy is a vulnerable time in settings such as sub-Saharan Africa, and is associatedwith exposure to a multitude of physiological, social and psychological risks. High HIV prevalence, and the fact that many women will test for HIV for the first time during their pregnancy, has raised concern about women's psychological health during pregnancy. Depression during the antenatal period is of public health concern as it has been shown to be associated with poorer foetal and delivery outcomes, risky behaviours, and poorer uptake of antenatal care. Antenatal depression is a predictor of postnatal depression, and postnatal depression has been associated with poor maternal sensitivity and attachment in mothers which is known to result in increased behavioural and developmental difficulties in children. The aim of this research was to provide a clear, in depth and culturally sensitive understanding of the manifestation of depression in pregnant women in a rural area with high HIV prevalence in South Africa. The research method included a diagnostic assessment of depression in 109 women in their third trimester of pregnancy, and an in-depth qualitative examination of the contextual framework within which HIV testing and depression are experienced with a sub-sample of 56 women. The quantitative results demonstrated that the prevalence of antenatal depression was high (46.7%), with close to half of the women being diagnosed with depression. Presentations of depression most frequently included disturbances in mood, loss of interest and suicide ideation.Symptoms which overlap with common side effects of pregnancy such as loss of energy and weight change did not result in an overestimation of depression. Likewise, very little evidence of the somatisation of depression, or particular cultural barriers to the diagnosis of depression based on DSM-IV criteria was found. Rates of suicide ideation were high and equally common among HIV positive as HIV negative women. Factors significantly associated with depression included living within a family homestead, access to a regular source of income and practical support from a partner. Both income and partner support had a negative association with depression. Living away from a family or parental home had a positive association with depression. The results showed that the Edinburgh Postnatal Depression Scale (EPDS) was effective in identifying depression and that a shorter three item version was as effective as longer versions. A positive score for depressed mood on the EPDS was significantly associated with HIV,suggesting that the EPDS is a good screening tool for elevated psychological risks among HIV positive women post HIV testing. Qualitative results showed that having an unsupportive partner and the occurrence of relationship or familial conflict played an important role in the development of emotional distress during pregnancy and resulted in a high number of unwanted pregnancies. Partner and familial conflict was intertwined with cultural practices which govern the acceptability of childbearing among unmarried women and the social recognition of partnerships and paternal responsibilities. Testing for HIV was considered a stressful life event for all women regardless of their HIV status and was a particularly negative life event for women who tested HIV positive or for women who had concerns over partner infidelity. Disclosure among HIV positive women frequently lead to increased partnership conflict. Qualitative findings suggested that depression and emotional distress after HIV testing did interfere with women's ability to engage with prevention messages. Women who were coping well with learning their HIV positive status had high levels of family disclosure and subsequent family support in common.The implication of this research is that it is important that public health programmes screen for depression among childbearing women.These data suggests that a shorter three item version of the EPDS along with screening for partner and family support or conflict would effectively detect most women at high risk for depression. Likewise, public health interventions for women with depression which are implemented in primary health care facilities and in isolation of the partnership and familial context within which depression occurs are not likely to be effective. Further research is needed to establish the precise prevalence of antenatal and postnatal depression in women at high risk for HIV; to validate the effectiveness of a shorter screening tool in resource limited settings; and to establish risk and protective factors, and trimester specific risks which could inform the design of cost effective interventions in poorly resourced settings.
