Association of Occupational Trajectories With Alcohol Use Disorders in a Longitudinal National Survey Journal of Occupational and Environmental Medicine 56,7 (July 2014): 700-707. Also: https://journals.lww.com/joem/Fulltext/2014/07000/Association_of_Occupational_Trajectories_With.4.aspx Cohort(s): NLSY79 Publisher: American College of Occupational and Environmental Medicine Keyword(s): Alcohol Use; Occupational Information Network (O*NET); Occupational Status; Occupations Permission to reprint the abstract has not been received from the publisher. Objectives: We investigated longitudinal associations between occupation and alcohol use disorders (AUDs) across early- to mid-adult life. Methods: Longitudinal trajectories of work substantive complexity were constructed by growth mixture modeling of occupational data from the National Longitudinal Survey of Youth 1979 and O*NET work variables. The association between work trajectories and AUDs was modeled adjusting for education. Results: Lower work trajectories were associated with higher AUD prevalence and incidence. Incident AUDs were associated with a subsequent decline in work trajectory class for both high and low initial classes, more strongly in women despite lower overall AUD incidence. Conclusions: Low work trajectory is associated with increased AUD prevalence. Development of an AUD may presage risk of decline in work substantive complexity. These findings suggest reinforcing relations between the development of AUD and occupational course at midlife. |

An Examination of the Effects of Occupational Trajectories and Psychosocial Characteristics of Work on Racial/Ethnic Disparities in Birth Outcomes Ph.D. Dissertation, University of Connecticut, 2012 Cohort(s): NLSY79 Publisher: ProQuest Dissertations & Theses (PQDT) Keyword(s): Birthweight; Ethnic Differences; Health Factors; Hispanics; Maternal Employment; Occupational Information Network (O*NET); Occupations; Pre/post Natal Behavior; Racial Differences Permission to reprint the abstract has not been received from the publisher. Health disparities are a major public health concern, as are adverse reproductive health outcomes. One of the most persistent health disparities between blacks and whites is that of adverse birth outcomes. This research aimed to evaluate whether racial/ethnic differences in occupational substantive complexity (SC) trajectories were a significant contributor to racial/ethnic disparities in low birth weight (LBW) and preterm delivery (PTD). In addition, this research evaluated racial/ethnic disparities in occupational pathways and the effects on pregnancy outcomes of work that does not fully engage prior education. This was a longitudinal study that analyzed secondary data from the National Longitudinal Study of Youth (NLSY79), combined with occupational characteristics data from the Occupational Information Resource Center (O*NET). Data analysis involved descriptive analysis as well as generalized linear models (GLM) and generalized estimated equations (GEE), which were constructed to examine the associations between outcome and predictor variables, and to estimate the risk of LBW and PTD. Additionally, structural equation modeling (SEM) and general growth mixture models (GGMM) were employed to determine the main effects of longitudinal occupational trajectories relative to educational attainment on LBW and PTD, with particular attention to racial differences. The results of LBW analysis supported the study hypothesis. Minority mothers were over represented in low SC trajectories, and black mothers in particular showed an increased risk of giving birth to a LBW infant. Furthermore, foreign-born Hispanic mothers showed favorable outcomes in comparison to their US-born counterparts. The findings also supported the hypothesis of mediation by SC trajectories of the association between education and LBW. PTD results were inconclusive. Black mothers had an increased risk of PTD as hypothesized, however the mediating effects of SC trajectories were greater for Hispanics. This study is of great relevance to the field of Public Health, as it is adding to the body of knowledge on how disparities in birth outcomes may in part be a consequence of occupational characteristics, which in themselves are expressions, and results of deeper disparities. Additionally with more women working during the course of their pregnancy, this study will be beneficial to women's reproductive health. |

Construction of Early and Midlife Work Trajectories in Women and Their Association With Birth Weight American Journal of Public Health 104,S1 (February 2014): S58-S64. Also: http://ajph.aphapublications.org/doi/abs/10.2105/AJPH.2013.301401 Cohort(s): NLSY79 Publisher: American Public Health Association Keyword(s): Birthweight; Labor Force Participation; Life Course; Modeling, Growth Curve/Latent Trajectory Analysis; Occupational Information Network (O*NET) Permission to reprint the abstract has not been received from the publisher. Objectives. We derived trajectories of the substantive complexity (SC) of work across mid-adult life in women and determined their association with term birth weight. SC is a concept that encompasses decision latitude, active learning, and ability to use and expand one’s abilities at work. Methods. Using occupational data from the National Longitudinal Survey of Youth 1979 and O*NET work variables, we used growth mixture modeling (GMM) to construct longitudinal trajectories of work SC from the ages of 18 to 34 years. The association between work trajectories and birth weight of infants born to study participants was modeled using generalized estimating equations, adjusting for education, income, and relevant covariates. Results. GMM yielded a 5-class solution for work trajectories in women. Higher work trajectories were associated with higher term birth weight and were robust to the inclusion of both education and income. A work trajectory that showed a sharp rise after age 24 years was associated with marked improvement in birth weight. Conclusions. Longitudinal modeling of work characteristics might improve capacity to integrate occupation into a life-course model that examines antecedents and consequences for maternal and child health. |
