Problems in the Latina paradox: measuring social support for pregnant immigrant women from Mexico.

Women who have immigrated to the United States from Mexico have better than expected birth outcomes. Part of this apparent health 'paradox' has been explained by high levels of social support which are thought to offset known risk factors for low birth weight. Yet common measures of social support during pregnancy suffer from presumptions of cultural homogeneity and a-priori definitions of meaningful social support. Analysis of qualitative data from ethnographic research with 28 low-income immigrant women from Mexico living in south Texas demonstrates that preferences for certain kinds of social support vary considerably, based on how each woman makes meaning of being pregnant. This diversity is one more piece of evidence that minority cultures cannot be essentialised in health disparities research. By not measuring the diversity of desire for different kinds of support, existing correlations between social support and birth outcomes may obscure other important psychosocial mediators, such as pregnancy-related social status, that could impact birth outcomes. Moreover, a measure of pregnancy-related status may offer a more thorough explanation of the 'protective effect' that could be explored independent of immigrant status.
