Behavioral interventions related to plastic waste management in low-and middle-income countries
Addressing the mounting plastic waste problem requires system-level solutions, along with interventions that promote behavioral change. In low-resource countries, inadequate, if not absent, waste management systems lead to unsafe disposal practices, including open burning. While theory-informed approaches are essential for identifying enablers and barriers to target behavior change, their application is limited in these settings. Given the lack o…
“We remember the pain”
Rates of homelessness among adults aged 50 and over are rising. Common strategies for exiting homelessness rely on social and family support. However, intergenerational trauma may disrupt these social support networks and contribute to homelessness. Understanding the impact of intergenerational trauma on living with family or friends may give insight into addressing homelessness among older adults. We purposefully sampled 46 adults who reported l…
Evaluating the implementation of weekly rifapentine-isoniazid (3HP) for tuberculosis prevention among people living with HIV in Uganda
Three months of isoniazid-rifapentine (3HP) is being scaled up for tuberculosis (TB) preventive treatment (TPT) among people living with HIV (PLHIV) in high-burden settings. More evidence is needed to identify factors influencing successful 3HP delivery. We conducted a qualitative assessment of 3HP delivery nested within the 3HP Options Trial, which compared three optimized strategies for delivering 3HP: facilitated directly observed therapy (DOT…
They made me feel like I mattered”
In this study, respondents perceived this MCT model as a desirable alternative to law enforcement and other first responders while satisfying immediate survival needs. To improve MCT's effectiveness for PEH, these teams could collaborate with follow-up providers capable of linking clients to resources and services that can meet their long-term needs. However, these teams may not be able to meaningfully impact the longstanding and complex issues t…
Evaluating the outcomes and implementation determinants of interventions co-developed using human-centered design to promote healthy eating in restaurants
Background Restaurants are an emerging yet underutilized setting to facilitate healthier eating, particularly among minoritized communities that disproportionately experience health inequities. The present study aimed to examine outcomes from interventions co-developed using Human-Centered Design (HCD) in two Latin American restaurants, including sales of healthier menu items (HMI) and the consumer nutrition environment. In addition, we aimed to …
Barriers and facilitators to resolving older adult homelessness through stays with family
Living with family and friends is a common strategy used to prevent or exit homelessness, but little is known about structural barriers that impede family and friends' ability to provide temporary or permanent housing for older homeless adults. We conducted semi-structured interviews with 46 homeless participants from the HOPE HOME study, a cohort of 350 community-recruited homeless adults age 50 or older in Oakland, CA, who reported having staye…
Temporary stays with housed family and friends among older adults experiencing homelessness
Background: The proportion of adults age 50 and older experiencing homelessness is growing. People at risk for homelessness may stay with family and friends to prevent homelessness. Moving in with housed family and friends is a strategy used to exit homelessness. Little is known about these stays with family and friends. This study examined the motivations for and challenges of older adults experiencing homelessness staying with or moving in with…
Working with Data in Adult English Classrooms
Throughout COVID-19, health officials have relied on data visualizations to communicate urgent messages about the spread of the virus and preventative measures. Relatively few efforts have employed participatory engagement with communities who have experienced a disproportionate burden of COVID-19 illness to shape these communications. Sociologist W.E.B. Du Bois viewed data visualization as an approach to changing the way people think about thems…
Promoting healthy eating in Latin American restaurants
LARs can positively influence eating behaviors but doing so requires balancing public health goals and business profitability. LARs also faced various constraints that require different levels of assistance and resources, underscoring the need for innovative engagement approaches, including incentives, to promote these changes
Study Designs to Assess Real-World Interventions to Prevent Covid-19
Background: In the face of the novel virus SARS-CoV-2, scientists and the public are eager for evidence about what measures are effective at slowing its spread and preventing morbidity and mortality. Other than mathematical modeling, studies thus far evaluating public health and behavioral interventions at scale have largely been observational and ecologic, focusing on aggregate summaries. Conclusions from these studies are susceptible to bias fr…
Area Characteristics and Consumer Nutrition Environments in Restaurants
Hispanics in the USA, particularly those of Caribbean descent, experience high levels of diet-related diseases and dietary risk factors. Restaurants are an increasingly important yet understudied source of food and may present opportunities to positively influence urban food environments. We sought to explore food environments further, by examining the association between neighborhood characteristics and restaurant consumer nutrition environments…

Purpose We evaluated outcomes of trainees who have completed Certificate program in Implementation Science at the University of California San Francisco. Methods All students who completed the in-person Certificate Program (2008-2015), or the online Certificate Program (2016-2017) were eligible for our study. We assessed the potential impact of the Certificate Program on the professional development of trainees, through participant surveys on the…
Ethnic Restaurant Nutrition Environments and Cardiovascular Health
Our application of the NEMS-R to HC restaurants in NYC revealed areas for potential future interventions to improve food offerings and environmental cues to encourage healthful choices
Selecting and Improving Quasi-Experimental Designs in Effectiveness and Implementation Research
Interventional researchers face many design challenges when assessing intervention implementation in real-world settings. Intervention implementation requires holding fast on internal validity needs while incorporating external validity considerations (such as uptake by diverse subpopulations, acceptability, cost, and sustainability). Quasi-experimental designs (QEDs) are increasingly employed to achieve a balance between internal and external va…
The Health Literacy of U.S. Immigrant Adolescents
Immigrant adolescents are the fastest-growing sector among U.S. youth, but they receive little attention in health literacy research. Immigrant adolescents are a diverse population tasked with mastering new literacies while also navigating new social systems. Many immigrant adolescents serve as important linguistic and cultural resources in their families and local communities, and yet their contributions (and struggles) as new navigators of our …

The Important Role of Binational Studies for Migration and Health Research
The impact of migration on health is an important and growing concern worldwide. We conducted a literature review of published health literature in PubMed, between January 1999 and February 2015, representing studies including US and Mexico samples and the title word “binational”. Fifty‐nine studies representing three types of study designs were identified. The health issues examined included chronic conditions, mental health, substance abuse, re…
Navigating changing food environments – Transnational perspectives on dietary behaviours and implications for nutrition counselling
United States (US) migrants are often characterised as experiencing unhealthy nutrition transitions. 'Looking-back' into dietary behaviours and the processes that affect dietary changes before migration may improve counselling interventions. We conducted a qualitative study of an indigenous Zapotecan transnational community based in Monterey, California, and Oaxaca, Mexico. Four focus groups and 29 interviews were conducted with transnational par…
An Examination of Cesarean and Vaginal Birth Histories Among Hispanic Women Entering Prenatal Care in Two California Counties with Large Immigrant Populations
Repeat cesarean delivery (CD) rates among US Hispanic women are the highest of all racial/ethnic groups (90%). Vaginal birth after cesarean (VBAC) is an alternative delivery method, but requires medical records documentation of a non-vertical incision and favorable conditions in the current pregnancy. VBAC rates for Hispanic women are extremely low. This study explores the birth histories and medical records access among Hispanic women in Califor…
The influence of indigenous status and community indigenous composition on obesity and diabetes among Mexican adults
Savoring the Taste of Home
The Mexican State has known for decades that its rural ceramic producing communities have had to increase the lead content of their glaze in response to lower grade fuel supplies for their adobe kilns. This has resulted in increased Blood Lead Levels (BLLs) among their poorer populations who not only produce the ceramic but also depend on it as their primary source of cookware. Lead is a subtle crippler that produces many health maladies that mim…
Globalization, Binational Communities, and Imported Food Risks
Objectives. Although the burden of lead poisoning has decreased across developed countries, it remains the most prevalent environmental poison worldwide. Our objective was to investigate the sources of an outbreak of lead poisoning in Monterey County, California. Methods. An investigation in 3 county health department clinics in Monterey County, California, was conducted between 2001 and 2003 to identify risk factors for elevated blood lead level…
HIV infection among women in prison
The relative contributions of needle use practices and sexual behaviors to human immunodeficiency virus (HIV) antibody seropositivity among 394 women incarcerated in Quebec were determined by risk factor assessment and serology with a nonnominal methodology. HIV positivity was found in 6.9% (95% confidence interval [CI] = 4.6, 9.9) of all participants and in 13% (95% CI = 8.6, 18.6) of women with a history of injection drug use. HIV seropositivit…
Workplace health hazards
Between 1981-1986 a state-based occupational health telephone hotline received more than 8,000 inquiries on over 3,000 hazardous agents. Major caller groups were employees (37%), employers (20%), health care providers, primarily physicians (19%), government agencies (12%), and labor unions (6%). Employees were the fastest growing caller group. Callers inquired about general health hazards of chemicals (65%), the relation of symptoms to work (22%)…
