This study investigates whether dynamic measures of a woman's socioeconomic status may help to explain the persistent and largely intractable disparity observed in low birth weight outcomes between black and white women in the United States. A class of regression modeling suitable for longitudinal data called generalized linear mixed modeling was employed to examine the relationship between a low birth weight outcome and socioeconomic trajectory measures, while accounting for additional socio demographic and health covariates. Multiple imputation was employed to handle missingness across independent covariates. Results provide evidence for the importance of the timing of events within poverty and blue collar trajectories, where patterns of poverty or occupational status possessing subtle differences were associated with different odds of a low birth weight outcome. Fluctuations in socioeconomic status from poverty status, to non poverty status, to poverty status, was associated with an odds ratio of 2.46 compared to women never having been poor during the three years of interest (the birth year and two years prior). The odds ratio associated with this pattern was in fact stronger than for a woman in poverty for the entire duration, which placed one at an odds two times in excess of never having experienced poverty. The year of the birth appeared to be an important factor, as all significant associations were observed in poverty patterns where poverty was experienced in the birth year. Adjusting for marital status removed the association between being in constant poverty and the increased odds of low birth weight; however remaining relationships persisted. Stability (i.e. being continuously in one status) appeared to be preferable over fluctuations in job status. The year of the birth was again significant in the occupational model, where being in blue collar status at birth was associated with almost a five-fold increased odds of low birth weight. Women who entered the labor force in a blue collar job were at a two times greater odds of low birth weight. Regarding the occupational trajectory, adjustment for marital status did little to modify existing relationships. Overall, poverty and blue collar trajectory measures attenuated the relationship between low birth weight and race; however a significant disparity between black and white women continued to exist. The significance of these results is discussed not only as it relates to maternal and infant health policy but also broader social policy. (Abstract shortened by UMI.)
