RESUMO
OBJECTIVE: This study examines the maternal characteristics and birth outcomes of infants of U.S. resident Asian-Indian-American (AIA) mothers and compares those to infants of U.S. resident Whites and African-American (AA) mothers. METHODS: Single live births to U.S. resident mothers with race/ethnicity coded on birth certificate as AIA, non-Hispanic White, or non-Hispanic AA were drawn from NCHS 1995 to 2000 U.S. Linked Live Birth/Infant Death files. RESULTS: Compared to AAs or Whites, AIAs have the lowest percentage of births to teen or unmarried mothers and mothers with high parity for age or with low educational attainment. After taking these factors into account, AIA had the highest risk of LBW, small-for-gestational age and term SGA births but a risk of infant death only slightly higher than Whites and far less than AAs. CONCLUSIONS: The birth outcomes of AIAs do not follow the paradigm that more impoverished minority populations should have greater proportions of low birth weight and preterm births and accordingly greater infant mortality rates.

OBJECTIVE: The objective of this study was to examine risks of preterm births, quantify the explanatory power achieved by adding medical and obstetric risk factors to the models and to examine temporal changes in preterm birth due to changes in Medicaid eligibility and the establishment of a maternal-fetal medicine referral system. 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=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 ≤32 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 ≤32 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.

OBJECTIVES: We examined the manner in which state public health agencies have organized their operations to accomplish the goals associated with emergency preparedness (EP) funds. We also examined the leadership challenges associated with the effective utilization of preparedness funds. METHODS: The websites of all 50 state public health organizations in the USA were examined in order to determine the different approaches that states have used to organize for preparedness. Thirty-eight states provided sufficient information to allow for classification of their organizational approach to EP. Telephone interviews were conducted with representatives in three model states to obtain deeper insights into the organizational approach. RESULTS: Three predominant organizational models were identified as a means to address the challenge of organizing for preparedness. The results confirmed the equifinality principle of organization (there may be more than one equally effective way to organize) and demonstrated that, contrary to the prescription of early management thought, there is no 'one best way' to organize. Leadership rather than formal management emerged as the primary contributor to perceived EP. Specifically, interviews with preparedness professionals indicated that they believed expert power was more important than position power and the ability to negotiate and influence through persuasion was more important than formal authority. CONCLUSIONS: All three models contained, to a greater or lesser degree, elements of matrix management with the associated leadership challenges for emergency preparedness (EP) directors. Recommendations were provided for successful leadership in the context of EP directors in state departments of public health.
