Acknowledgments A big thank you to the following folks who made this dissertation possible: Jeffrey Roth who convinced ACHA to let me use their Medicaid data then linked it with the birth registry data. David Darr who persuaded the Florida DOH to let me use the birth registry data for free. Shane Troutman who figured out the reason no computer on campus would run my program was because they weren‟t powerful enough. He also rescued my hard drive and my dissertation after I destroyed my laptop by spilling coffee on it. David at the SAS Institute who patiently answered all my questions about programming code for logistic regression. Peter who was a thoughtful listener to my early conjectures about the influence of relationships on fetal position. My mom and dad who funded this dissertation and believed in me even when it seemed like I was doing something very strange. Sandy & Cheryl who always knew I would finish even when I thought I couldn‟t. My kitty Elsie who sat by me (or on my papers) through it all.
