Type 1 diabetes (T1D) is an autoimmune disease in which pathogenic lymphocytes target autoantigens expressed in pancreatic islets, leading to the destruction of insulin-producing β-cells. Zinc transporter 8 (ZnT8) is a major autoantigen abundantly present on the β-cell surface. This unique molecular target offers the potential to shield β-cells against autoimmune attacks in T1D.

Introduction: We compared behavioral risk factors and preventive measures among female breast cancer survivors, female survivors of other types of cancers, and women without a history of cancer. Survivorship health care indicators for the 2 groups of cancer survivors were compared.

Methods: Using data from the 2010 Behavioral Risk Factor Surveillance System, we calculated the proportion of women with risk factors and their engagement in preventive practices, stratified by cancer status (cancer survivors or women with no history of cancer), and compared the proportions after adjusting for sociodemographic characteristics.

This pilot project worked to establish linkages among community-based organizations, health care providers, and public health systems. The partnerships were created to help ensure identification, referral, and follow-up for community members with uncontrolled high blood pressure or pre-hypertension to lay the groundwork for sustainable referral and health education support systems in rural communities. The evaluation shows the project helped some participants control their blood pressure and change their blood pressure management behaviors.

Small area estimation is a statistical technique used to produce reliable estimates for smaller geographic areas than those for which the original surveys were designed. Such small area estimates (SAEs) often lack rigorous external validation. In this study, we validated our multilevel regression and poststratification SAEs from 2011 Behavioral Risk Factor Surveillance System data using direct estimates from 2011 Missouri County-Level Study and American Community Survey data at both the state and county levels.

Introduction: The Well-Integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN) public health program is designed to reduce the risk of heart disease and stroke among low-income, underinsured or uninsured women through clinical screenings, risk factor assessment, and lifestyle interventions. We assessed the effect of the Missouri WISEWOMAN program on the control of high blood pressure, total cholesterol, and blood glucose levels.

Methods: We calculated the proportion of participants (N = 1,130) with abnormal blood pressure, total cholesterol, or blood glucose levels at an initial screening visit who gained control at a follow-up visit 11 to 18 months later during a 7-year period from June 30, 2005, to June 29, 2012.

Objective: We examined the financial and social costs resulting from traumatic brain injury (TBI) in Missouri.

Methods: We computed mortality rates from death certificates, the direct cost of TBI from hospital and emergency department (ED) visit charges, the social cost in terms of years of potential life lost (YPLL) using an abridged Missouri life table, and the indirect financial cost in terms of lost productivity due to premature death for all TBI and four major causes of TBI in Missouri.

Results: During 2001-2005, a mean of 1358 lives were lost due to TBI in Missouri.

Objective: To evaluate the effectiveness of the peer counselling (PC) programme on breast-feeding initiation among participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Missouri, and to identify factors that facilitate breast-feeding initiation.

Design: We used the data from the 2006 Missouri Pregnancy Nutrition Surveillance System, Missouri Live Birth Records and the Missouri WIC programme to compare breast-feeding initiation rates between PC and non-PC agencies. We used multilevel logistic regression, with individual participants being nested within agencies, to control for individual- and agency-level characteristics.

Eliminating racial disparities in cancer is a key goal of national organizations and those in Missouri. The purpose of this study is to provide trends in cancer incidence (1996-2003) and mortality (1990-2005) over time with special emphasis on disparities between African-Americans and whites in Missouri. Overall changes in incidence rates suggest that by 2006 the racial disparity will be eliminated.

Background: With a secular trend of increasing colorectal cancer (CRC) screening, concerns about disparities in CRC screening also have been rising. It is unclear if CRC screening varies geographically, if area-level poverty rate affects CRC screening, and if individual-level characteristics mediate the area-level effects on CRC screening.

Methods: Using 2006 Missouri Behavioral Risk Factor Surveillance System (BRFSS) data, a multilevel study was conducted to examine geographic variation and the effect of area-level poverty rate on CRC screening use among persons age 50 or older.
