Factors associated with infant low birth weight among Medicaid reimbursed births in Iowa, 2010

The purpose of the fact sheet is to highlight the characteristics of Iowa women who gave birth to low birth weight infants during 2010 and to guide decision makers in implementing programs that improve the health outcomes of the mothers and infants who rely on Medicaid coverage.

2010 Iowa Medicaid – Birth Certificate – Barriers to Prenatal Care Project Match Report Summary of Findings for Medicaid Reimbursed Births

The purpose of the fact sheet is to summarize the Iowa Barriers to Prenatal Care Project’s survey results for women with Medicaid reimbursed births during 2010. This information will be used to guide decision makers in implementing programs that improve the health outcomes of the women and infants who rely on Medicaid coverage.

Birth Certificate Match Report Comparison of Maternal Demographic Characteristics Medicaid vs. Non-Medicaid Reimbursed Births – 2010 Iowa Medicaid

The purpose of the fact sheet is to highlight the characteristics of Iowa women who gave birth in Iowa during calendar year 2010, with a focus on women with labor and delivery costs reimbursed by Medicaid compared to women with labor and delivery costs not reimbursed by Medicaid. This information will be used to guide decision makers in implementing programs that improve the health outcomes of the women and infants who rely on Medicaid coverage.

Investigation of the Impact of Dual-Lane Axle Spacing on Lateral Load Distribution, 2016

The spacing of adjacent wheel lines of dual-lane loads induces different lateral live load distributions on bridges, which cannot be determined using the current American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) or Load Factor Design (LFD) equations for vehicles with standard axle configurations. Current Iowa law requires dual-lane loads to meet a five-foot requirement, the adequacy of which needs to be verified. To improve the state policy and AASHTO code specifications, it is necessary to understand the actual effects of wheel-line spacing on lateral load distribution. The main objective of this research was to investigate the impact of the wheel-line spacing of dual-lane loads on the lateral load distribution on bridges. To achieve this objective, a numerical evaluation using two-dimensional linear elastic finite element (FE) models was performed. For simulation purposes, 20 prestressed-concrete bridges, 20 steel bridges, and 20 slab bridges were randomly sampled from the Iowa bridge database. Based on the FE results, the load distribution factors (LDFs) of the concrete and steel bridges and the equivalent lengths of the slab bridges were derived. To investigate the variations of LDFs, a total of 22 types of single-axle four-wheel-line dual-lane loads were taken into account with configurations consisting of combinations of various interior and exterior wheel-line spacing. The corresponding moment and shear LDFs and equivalent widths were also derived using the AASHTO equations and the adequacy of the Iowa DOT five-foot requirement was evaluated. Finally, the axle weight limits per lane for different dual-lane load types were further calculated and recommended to complement the current Iowa Department of Transportation (DOT) policy and AASHTO code specifications.
