Study Design: The study used data from the 2001 to 2005-linked Arkansas (AR) Medicaid claims and birth certificates of preterm and term singleton deliveries (N ¼ 89 459). Logistic regression modeled the association among gestational age, demographic characteristics and risk factors, pooled and separately by year. Result: Physiological risk factors were additive with demographic factors and explained more of the preterm birth p32 weeks than later preterm birth. Changing eligibility requirements for Medicaid recipients and increasing the financial threshold from 133 to 200% of federal poverty level had an impact on temporal changes. The proportion of births p32 weeks declined to 33%, from 3.0 to 2.0. However, later preterm births declined and then increased in the last year. Conclusion: Physiological conditions are strongly associated with early preterm birth. Maternal behaviors and other stressors are predictive of later preterm birth. Unmeasured effects of poverty continue to have a role in preterm birth. Further examination of the referral system is needed.

This article describes the methodological issues that make studying homebound older adults especially vulnerable to therapeutic misconception and researcher role conflict and offers practical strategies for researchers to deal with these problems when studying this population. In writing this article, we draw on more than a decade of descriptive and intervention research focusing exclusively on the homebound older population in which the authors have collaborated. Therapeutic misconception and researcher role conflict may occur because of methodological issues related to the recruitment of participants, the "homebound" status of participants, and the home setting as the interview site. Particular care is required on the part of the researcher to address these ethical issues. This may be accomplished especially through clear communication during the informed consent process with participants and in scientific communication with colleagues.
