All of Us participant perspectives on the return of value in research.

Purpose: To understand participant preferences for receiving specific types of research information, whether information preferences vary across sociodemographic groups, and the types of health providers participants could access to understand returned information.

Methods: All of Us Research Program participants completed a value of returning research information survey. Stratified sampling was implemented to enhance participant diversity and avoid noncoverage.

Integrating participants as partners in research governance and operations: an approach from the Research Program Engagement Core.

Objectives: During the last two decades, researchers and funders increasingly recognised the value of engaging patients and communities in research. Despite progress, community engagement remains challenging. There are few examples of successful participant engagement in governance of large-scale research programmes.

Needs, Priorities, and Recommendations for Engaging Underrepresented Populations in Clinical Research: A Community Perspective.

Engaging underrepresented groups in outcomes research is a public health priority for reducing health and health care disparities; yet, engaging these groups is challenging. Failure to involve these underrepresented populations in research further exacerbates these disparities. This article presents the health and research priorities of diverse groups of underrepresented populations in biomedical research, their concerns for participating in research, and strategies to engage them in their healthcare and research studies.

Increased vitamin D and calcium intake associated with reduced mammographic breast density among premenopausal women.

Vitamin D has been identified as a weak protective factor for postmenopausal breast cancer (relative risk, ~0.9), whereas high breast density has been identified as a strong risk factor (relative risk, ~4-6). To test the hypothesis that there is an association between vitamin D intake, but not circulating vitamin D levels, and mammographic breast density among women in our study, we conducted a cross-sectional study of 165 screening mammography patients at Nashville General Hospital's Breast Health Center, a public facility serving medically indigent and underserved women.

The interaction of perceived risk and benefits and the relationship to predicting mammography adherence in African American women.

Purpose/objectives: To test the interaction of perceived risk and benefits and how they impact stage of mammography readiness and adherence.

Design: Cross-sectional study.

Setting: Community gathering centers and healthcare clinics across Indiana.

Replication and functional genomic analyses of the breast cancer susceptibility locus at 6q25.1 generalize its importance in women of chinese, Japanese, and European ancestry.

We evaluated the generalizability of a single nucleotide polymorphism (SNP), rs2046210 (A/G allele), associated with breast cancer risk that was initially identified at 6q25.1 in a genome-wide association study conducted among Chinese women. In a pooled analysis of more than 31,000 women of East-Asian, European, and African ancestry, we found a positive association for rs2046210 and breast cancer risk in Chinese women [ORs (95% CI) = 1.

Psychosocial determinants of mammography follow-up after receipt of abnormal mammography results in medically underserved women.

This article targets the relationship between psychosocial determinants and abnormal screening mammography follow-up in a medically underserved population. Health belief scales were modified to refer to diagnostic follow-up versus annual screening. A retrospective cohort study design was used.

The "Got D'ViBE?" study: an inter-institutional project assessing vitamin D and mammographic breast density.

A multi-institutional collaboration was forged to implement a study of the relationship between Vitamin D and breast density among medically underserved women. This effort resulted in techniques to measure vitamin D levels, breast density, and sunlight exposure. Outcomes from this collaboration may provide insight to researchers conducting similar investigations.

Breast cancer knowledge and barriers to mammography in a low-income managed care population.

Background: Low-income women experience multiple barriers to screening mammography. This study explored cancer knowledge as a point of intervention to reduce overall barriers.

Methods: A survey of breast cancer knowledge and barriers was obtained from 173 low-income female residents of Middle Tennessee, > or =40 years, enrolled in the state managed care organization and nonadherent to mammography.

Obesity, gynecological factors, and abnormal mammography follow-up in minority and medically underserved women.

Background: The relationship between obesity and screening mammography adherence has been examined previously, yet few studies have investigated obesity as a potential mediator of timely follow-up of abnormal (Breast Imaging Reporting and Data System [BIRADS-0]) mammography results in minority and medically underserved patients.

Methods: We conducted a retrospective cohort study of 35 women who did not return for follow-up >6 months from index abnormal mammography and 41 who returned for follow-up < or =6 months in Nashville, Tennessee. Patients with a BIRADS-0 mammography event in 2003-2004 were identified by chart review.

Genome-wide association study identifies a new breast cancer susceptibility locus at 6q25.1.

We carried out a genome-wide association study among Chinese women to identify risk variants for breast cancer. After analyzing 607,728 SNPs in 1,505 cases and 1,522 controls, we selected 29 SNPs for a fast-track replication in an independent set of 1,554 cases and 1,576 controls. We further investigated four replicated loci in a third set of samples comprising 3,472 cases and 900 controls.

Energy balance, physical activity, and cancer risk.

This chapter posits that cancer is a complex and multifactorial process as demonstrated by the expression and production of key endocrine and steroid hormones that intermesh with lifestyle factors (physical activity, body size, and diet) in combination to heighten cancer risk. Excess weight has been associated with increased mortality from all cancers combined and for cancers of several specific sites. The prevalence of obesity has reached epidemic levels in many parts of the world; more than 1 billion adults are overweight with a body mass index (BMI) exceeding 25.

Barriers to diagnostic resolution after abnormal mammography: a review of the literature.

Breast cancer remains the most common cancer in women, and screening mammography is the best method for early detection. Approximately 10% to 15% of women undergoing screening mammography have abnormal or incomplete findings that require further diagnostic studies. The time to follow up is reported to be between 9 weeks and more than 19 weeks.

Timing is everything: methodologic issues locating and recruiting medically underserved women for abnormal mammography follow-up research.

Objectives: Recruiting underserved women in breast cancer research studies remains a significant challenge. We present our experience attempting to locate and recruit minority and medically underserved women identified in a Nashville, Tennessee public hospital for a mammography follow-up study.

Study Design: The study design was a retrospective hospital-based case-control study.

Energy balance, insulin resistance biomarkers, and breast cancer risk.

Background: American women are five times more likely to be at risk for breast cancer than women from Asian countries. Epidemiologic studies have linked energy balance to an increased risk of breast cancer, yet few studies have investigated potential mediators of this association with Chinese women. We examined the above association by blood levels of insulin-like growth factors (IGFs), binding proteins, and C-peptide in the Shanghai Breast Cancer Study (SBCS), a case-control study conducted among 1,459 breast cancer cases and 1,556 healthy Chinese women from 1996 and 1998.
