Disparities in Birth Weight Between Non-Hispanic Blacks and Non-Hispanic Whites: The Effect of Rural Residency MS Thesis, Utah State University, 2009.

The purpose of this study is to assess the prevalence of low birth weight among non-Hispanic Blacks and non-Hispanic Whites along the rural/urban continuum, as well as the combined effect of being both non-Hispanic Black and residing in a completely rural county. Degree of social isolation and lack of support are proposed mechanisms for explaining disparities in low birth weight for Blacks in rural counties. Using data from the National Longitudinal Survey of Youth 1979 (NLSY79) and the National Longitudinal Survey of Youth 1979 Child (NLSY79-C) datasets, logistic regression models were used to estimate the odds of low birth weight. Key variables employed in these models include race/ethnicity, a five category measure of counties by degree of rural versus urban residence, interaction terms for race by county categorization, measures of the degree of community level support or isolation, household composition as a measure of the family support structure, access to medical care, maternal SES, birth characteristics, and maternal pregnancy behavior. Results demonstrate that Blacks have much higher odds of low birth weight than Whites and living in a completely rural county exacerbates disadvantage in birth weight outcomes for non-Hispanic Blacks but not for non-Hispanic Whites. The community and household level support measures have little mediating effect on the magnitude of the negative birth weight outcomes found for non-Hispanic Blacks in the most rural counties. However, the first order effect for non-Hispanic Blacks was almost completely explained by the presence of the father in the household when interaction effects for race and place of residence were also included in the model. |

A Longitudinal Study of Past Influences on Migration Presented: Detroit MI, Population Association of America Annual Meeting, April 2009. Also: http://paa2009.princeton.edu/download.aspx?submissionId=91777 Cohort(s): NLSY79 Publisher: Population Association of America Keyword(s): Age and Ageing; Life Cycle Research; Migration Permission to reprint the abstract has not been received from the publisher. Migration literature usually describes the age pattern of adult migration frequency as highest in young adulthood, with a subsequent gradual decline in the frequency of migration events with age. This tapering off in a person's life describes an assumed universal, life cycle of migration. There is also an embedded assumption that each migration event in an individual's life is independent of all other migration events and that each migration is simply a result of the costs and benefits of a move at that point in time. The idea that each move is independent of other moves, coupled with a universally applied life cycle of migration for an individual has partially stemmed from data limitations bred from cross-sectional studies. This research utilizes longitudinal data that enables a more thorough analysis of the two assumptions listed above. We hypothesize that each migration event is correlated to other migration events in an individual's life. A migration event is defined as a change in county of residence, defined by federal information processing standards codes (FIPS codes). This study shows that the age of an individual's first adult migration differentially influences subsequent migration events. The frequency of primary migration events declines with age, meaning that there are fewer total numbers of primary migrations at later ages. But those who experience a primary migration at age 28 as opposed to age 18, for example, will begin their migration life cycle at that point, leading to a higher chance of subsequent migrations. By grouping cases by age at first migration, or primary migration, new patterns emerge that give a more detailed description of how migration occurs. Disaggregation by age group of first migration event reveals that the universally applied life cycle of migration as a gradual taper with age, no longer remains true. In fact, the same pattern as described in the life cycle of migration still occurs on the individual level, but this pattern begins at different time points based on the age of primary migration. |
