Migration, Social Organization, and the Sexual Partners of Mexican Men

How Does Migration Affect HIV Sexual Risk Behaviors Among Involuntary Bachelors? The Mediating Roles of Neighborhoods and Social Networks

The sex ratio imbalance in China since the 1980s has resulted in a large number of involuntary bachelors in rural China. Previous studies have found an association between migration and HIV sexual risk behaviors among involuntary bachelors, but how migration affects these bachelors' HIV sexual risk behaviors remain poorly understood. Using data from a cross-sectional survey in 2017 (a sample of 740 male respondents who had rural household registration, had never been married, and were aged 28-49 years), we investigated the relationship between migration and HIV sexual risk behaviors. Logistic regressions show that migration, neighborhood characteristics, and social networks were significantly associated with commercial sex and multiple sex partners, whereas only neighborhood characteristics and social networks were positively correlated with sexual partnership concurrency. Neighborhood characteristics and social networks mediated the relationships of migration with commercial sex and migration with multiple sex partners. Social networks mediated the association between neighborhood characteristics and concurrency. Multiple-step mediation analysis showed that the indirect effect of migration on commercial sex and multiple sexual partners through neighborhood characteristics and social networks was significant. Our findings suggest that further interventions should address neighborhood characteristics and social networks together.

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 Migration, Gender, and Health among Immigrant Latinos in Durham, NC 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.

Migration, Social Networks, and HIV Sexual Risk Behaviors Among Involuntary Bachelors in Rural China

In rural China there is an abnormally high male-biased sex ratio. The result is a large number of involuntary bachelors. This study examines how migration and social networks relate to bachelors' sexual risk behaviors. Data are from a cross-sectional questionnaire survey in which 740 male respondents who had rural household registration, had never married, and were aged 28 or older were interviewed in 2017. Logistic regression reveals that both migration and social networks place the bachelors at an especially high risk of HIV transmission by increasing the chance that they engage in commercial sex, whereas only social networks are significantly associated with sexual partnership concurrency. Additionally, social networks mediate the association between migration and commercial sex. This suggests that social networks play an important role in bachelors' risk of HIV transmission and that further intervention should address their social networks.

HIV Risk Behaviors and Correlates of Inconsistent Condom Use Among Substance Using Migrants at the Mexico/Guatemala Border

This study assessed correlates of inconsistent condom use with casual partners and the prevalence of sexual risk behaviors and STIs in the Mexico/Guatemala border region using a sample of 392 migrants (303 men, 85 women) who reported current substance use or problem drinking. We ran separate univariate logistic regression models for men and women, and multivariate logistic regression models for men only. Prevalence of syphilis was 1.2% among women and 2.3% among men; HIV prevalence was 2.4% among women and 1.3% among men. Inconsistent condom use with casual partners was higher in women with greater education and lower among women who sold sex. In men, less access to free condoms, drug use with sexual partners, and drug use before sex were independently associated with inconsistent condom use with casual partners. Sexual and substance use risk behaviors were common, and HIV/STI prevention efforts should target both genders and expand beyond most-at risk populations.
