With the increasing numbers of individuals surviving a diagnosis of cancer, an aging population, and more individuals experiencing multi-morbidity, primary care providers (PCPs) are seeing more patients with a history of cancer. Effective strategies are needed to adequately prepare the primary care workforce for the phase of cancer care now widely recognized as survivorship. A survivorship education program for rural primary care practices was developed using a community engagement process and delivered at the practice level by community health liaisons.

Social determinants of health affect a person's health at least as much as their interactions with the healthcare system. Increased patient activation and self-efficacy are associated with decreased cost and improved quality. Patient-reported health confidence has been proposed as a more easily measured proxy for self-efficacy.

Background: Green jobs are a rapidly emerging category of very heterogeneous occupations that typically involve engagement with new technologies and changing job demands predisposing them to physical stressors that may contribute to the development of joint pain.

Methods: We estimated and compared the prevalence of self-reported acute (past 30 days) joint pain between green and non-green collar workers using pooled 2004-2012 National Health Interview Survey (NHIS) data linked to the Occupational Information Network Database (O*NET).

Results: Green collar workers have a higher prevalence of acute joint pain as compared to non-green collar workers.

Cancer registry data are vital for the surveillance of cancer trends, but registries are limited in the number of data items that can be collected for hypothesis-driven research. Linkage with other databases can add valuable information and is a potentially effective tool for increasing our understanding of and identifying the causes of cancer and health disparities along the cancer continuum. We conducted a pilot study to link data from the 1981-2010 Florida Cancer Data System (FCDS) with data from the 1986-2009 National Health Interview Survey (NHIS).

Background: Although routine medication reviews in primary care practice are recommended to identify drug therapy problems, it is often difficult to get patients to bring all their medications to office visits. The objective of this study was to determine whether the medication review tool in the Agency for Healthcare Research and Quality Health Literacy Universal Precautions Toolkit can help to improve medication reviews in primary care practices.

Methods: The toolkit's "Brown Bag Medication Review" was implemented in a rural private practice in Missouri and an urban teaching practice in California.

Patient materials are often written above the reading level of most adults. Tool 11 of the Health Literacy Universal Precautions Toolkit ("Design Easy-to-Read Material") provides guidance on ensuring that written patient materials are easy to understand. As part of a pragmatic demonstration of the Toolkit, we examined how four primary care practices implemented Tool 11 and whether written materials improved as a result.

Background: Cancer survivors who engage in physical activity (PA) have improved quality of life, reduced fatigue, and lower mortality rates. We compare the percentage of cancer survivors meeting PA recommendations for US states, stratified by age and gender, to identify the need for PA education and intervention among cancer survivors.

Methods: Pooled data from the 1997-2010 National Health Interview Survey were used to determine and rank age-adjusted PA by state.

Background: Violence toward children (childhood victimization) is a major public health problem, with long-term consequences on economic well-being. The purpose of this study was to determine whether childhood victimization affects occupational prestige and income in young adulthood. We hypothesized that young adults who experienced more childhood victimizations would have less prestigious jobs and lower incomes relative to those with no victimization history.
