Migration and Contraception among Mexican Women: Assessing Selection, Disruption, and Adaptation.

Despite the sizeable impact of migration on childbearing, less is known about how it shapes contraceptive use undergirding fertility. We utilize binational survey data collected in 2006/7 by the study to assess how selection, disruption, and adaptation shape contraceptive use among Mexican migrant women. We address selectivity with respect to both socio-demographic and formative sexual initiation characteristics, comparing migrants to non-migrants in Mexico. We examine the disruptive effect of migration on contraception among migrant women sexually initiated in Mexico. Finally, we compare current methods between Mexican migrants and non-migrants to assess adaptation to U.S. contraceptive practices. We find migrant selectivity is less important than context in shaping immigrant women's contraceptive practices, though migrant women sexually initiated in the United States exhibit earlier and higher levels of contraceptive use than their migrant peers initiated in Mexico. Migration also disrupts contraceptive trajectories. Many migrants discontinue contraceptive use pre-migration in response to their husbands' solo migration. Partner separation also reduces contraceptive use immediately after migration. Finally, migrants show numerous signs of adaptation to the U.S. context, mainly via the adoption of oral contraception. The main obstacle for contraceptive use in Durham is lack of information about where to obtain it. Efforts to improve immigrants' reproductive health should recognize the deleterious effect of policies encouraging family separation. Healthcare must reach immigrant women soon after arrival, be attuned to pre-migration contraceptive practices, and recognize the unique vulnerabilities of women migrating at older ages.
