Do traditional economic theories of free riding behavior explain spatial clustering of HPV vaccine uptake?

Rationale: Geographic clusters of low vaccination uptake reduce the population-level efficacy of vaccination programs. However, little is known about the mechanisms that drive geographic patterns in vaccination rates. Traditional economic theory considers vaccination as a classic public good and suggests that individuals taking advantage of public goods by relying on others' immunization behavior without contributing toward themis a primary cause of low vaccination rates.

Who Is Food Insecure? Implications for Targeted Recruitment and Outreach, National Health and Nutrition Examination Survey, 2005-2010.

Introduction: Food insecurity is negatively associated with health; however, health needs may differ among people participating in food assistance programs. Our objectives were to characterize differences in health among people receiving different types of food assistance and summarize strategies for targeted recruitment and outreach of various food insecure populations.

Methods: We examined health status, behaviors, and health care access associated with food insecurity and receipt of food assistance among US adults aged 20 years or older using data from participants (N = 16,934) of the National Health and Nutrition Examination Survey from 2005 through 2010.

Validation of self-reported post-treatment mammography surveillance among breast cancer survivors by electronic medical record extraction method.

Little is known about validity of self-reported mammography surveillance among breast cancer survivors. Most studies have focused on accuracy among healthy, average-risk populations and none have assessed validity by electronic medical record (EMR) extraction method. To assess validity of survivor-reported mammography post-active treatment care, we surveyed all survivors diagnosed 2004-2009 in an academic hospital cancer registry (n = 1441).

Effectiveness of a community research registry to recruit minority and underserved adults for health research.

Background: Recruiting minorities and underserved populations into population-based studies is a long standing challenge. This study examined the feasibility of recruiting adults from a community research registry.

Methods: Ethnically diverse, bilingual staff attended health fairs, inviting adults to join a registry.

The colorectal cancer screening process in community settings: a conceptual model for the population-based research optimizing screening through personalized regimens consortium.

Reducing colorectal cancer mortality by promoting screening has been a national goal for two decades. The NCI's Population-Based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium is the first federal initiative to foster coordinated, transdisciplinary research evaluating the entire cancer screening process in community settings. PROSPR is creating a central data repository to facilitate research evaluating the breast, cervical, and colorectal cancer screening process across different patient populations, provider types, and delivery systems.

Validity of self-reported genetic counseling and genetic testing use among breast cancer survivors.

Introduction: Despite the value of genetic counseling (GC) and genetic testing (GT) for high-risk breast cancer survivors, little is known about their uptake and validity of self-report data. This study evaluated the accuracy of self-reported genetic counseling and testing rates among breast cancer survivors.

Methods: The current analysis focused on Stage 0-III female breast cancer survivors who were identified from an academic medical center's cancer registry and responded to a mailed survey (N = 452).
