We also determined whether changes in food security and stress were associated with changes in diet. Setting Wages is a prospective cohort study following 974 low-wage workers in Minneapolis, MN, wher...

This work investigates the associations between experiences of domestic minor sex trafficking and adolescent interpersonal violence victimizations, including intimate partner violence (IPV) and community violence. Abuse and violence in childhood are commonly proposed as risk factors for domestic minor sex trafficking. However, less is known about h...
Article
Background: Although stress is an established contributor to obesity (in general population studies), mechanisms to explain this association in African American women that incorporate culturally relevant frameworks have received little attention. Objective: To investigate how stress is associated with body mass index (BMI) in this population, we...

In parts of sub-Saharan Africa, where HIV prevalence is high, HIV is a leading cause of death among youths. Orphaned and separated youths are an especially vulnerable group, yet we know little about what influences their testing behavior. We conducted multiple logistical regression to examine theory-based predictors of past-year HIV testing among 4...
Article
Objective In 2018, Minneapolis began phased implementation of an ordinance to increase the local minimum wage to $15/hour. We sought to determine whether the first phase of implementation was associated with changes in frequency of consumption of fruits and vegetables, whole grain-rich foods, and foods high in added sugars among low-wage workers....

Background: Intimate partner violence can lead to deaths of one or both partners and others (i.e., corollary victims). Prior studies do not enumerate the societal cost of intimate partner violence-related fatalities, exclude corollary victims from most analyses, and do not describe groups who bear the highest societal costs from intimate partner vi...
Article
The food environment has been shown to influence dietary patterns, which ultimately affects nutrition-related diseases such as diabetes, obesity, and cardiovascular disease (CVD). Measures of food accessibility and socioeconomics were combined to develop the Food Environment Index (FEI), characterizing all U.S. counties between 2008 and 2016. Multi...
Article
Despite its widespread global adoption and use, studies have not examined measurement invariance of the 31-question World Health Organization Quality of Life–HIV BREF scale among HIV/AIDS patients. The current study seeks to (a) evaluate the scale’s internal consistency reliability, and concurrent validity, and (b) test if the same latent construct...

Research on stress-related health outcomes in African-American women often neglects "network-stress": stress related to events that occur to family, friends, or loved ones. Data from the African-American Women's Well-Being Study were analyzed to examine self-stress and network-stress for occurrence, perceived stressfulness, and association with sym...

Biobanks require new governance models that address their ethical and regulatory challenges. One model relies on stewardship of specimens throughout their life course. Here, we discuss findings from our survey of 456 U.S. biobank managers that addressed whether and how biobanks steward their specimens. The findings reveal that most biobanks do not...

Article
Many subjects in early phase clinical trials expect to benefit in some way from the research intervention. It is understandable that people hope for improvement in their condition, no matter what the evidence. Yet unreasonable expectation of medical benefit may reflect problems with informed consent: Investigators may not disclose clearly that dire...

The relationship between occupational stress, social support, and strain was investigated in a series of influential studies in the late 1970s and early 1980s. This continues to provide the most consistent support for the buffer hypothesis in the stress-strain literature. The authors argue that this support is more tenuous than it appears because t...
