How context matters: Demonstrating microgeographical differences in social capital and its implications for mental wellbeing in pregnancy with a novel bubble diagram technique.

There has been limited exploration of social capital at the contextual level in relation to maternal health, and in particular with the "obstetric transition" and associated mental health problems. In the North Central Province of Sri Lanka, with socio-culturally diverse communities, and a recent history of major conflict, the leading cause of maternal death is suicide. The objective of this study was to identify contextual patterns of social capital constructs that lead to poor maternal mental wellbeing, using a novel bubble visualisation technique, to demonstrate the use of data derived from qualitative approaches. We conducted a qualitative study of pregnant women based on diary entries (n = 41) and interviews (n = 38) in eight different communities of the Anuradhapura district of Sri Lanka. Bubble diagrams were constructed to visualize each context using the frequency and weight of responses given in diaries. Marital, family and neighbourhood cohesion were not homogenous in the district and the bubble diagrams displayed clear microgeographical patterns in which women living in specific communities had poorer mental wellbeing. Such techniques can be used to convey complex social capital implications in digestible way for policy makers and planners to enact locally specific strategies addressing health inequalities.
