TAILIEUCHUNG - Mothers’ Investments in Child Health in the U.S. and U.K.: A Comparative Lens on the Immigrant 'Paradox'

Hydroxyurea’s efficacy in sickle cell disease is generally attributed to its ability to raise the levels of Hb F in the blood; however, the mechanisms by which it does so are unclear. Early studies suggested that hydroxyurea is cytotoxic to the more rapidly dividing late erythroid precursors, resulting in the recruitment of early erythroid precursors with an increased capacity to produce Hb F. One recent study supports a nitric oxide-derived mechanism for the induction of Hb F by hydroxyurea, and another study suggests that ribonucleotide reductase inhibition is responsible for this increase in Hb F. Alternatively, hydroxyurea may be. | Mothers Investments in Child Health in the . and .

A Comparative Lens on the Immigrant Paradox Abstract Research on the immigrant paradox healthier behaviors and outcomes among more socioeconomically disadvantaged immigrants is mostly limited to the . Hispanic population and to the study of birth outcomes. Using data from the Fragile Families Study and the Millennium Cohort Study we expand our understanding of this phenomenon in several ways. First we examine whether the healthier behaviors of Hispanic immigrant mothers extend to other foreign-born groups including non-Hispanic immigrant mothers in the . and white South Asian black African and Caribbean and other largely East Asian immigrants in the including higher SES groups. Second we consider not only the size of the paradox at the time of the child s birth but also the degree of its persistence into early childhood. Third we examine whether nativity disparities are weaker in the . where a much stronger welfare state makes health information and care more readily accessible. Finally we examine whether differences in mothers instrumental and social support both inside and out of the home can explain healthier behaviors among the foreign-born. The results suggest that healthier behaviors among immigrants are not limited to Hispanics or to low SES groups that nativity differences are fairly persistent over time that the immigrant advantage is equally strong in both countries and that the composition and strength of mothers support plays a trivial explanatory role in both countries. These findings lead us to speculate that what underlies nativity differences in mothers .
