A Health Equity Task Force (HETF) of members from seven Centers funded by the National Cancer Institute’s (NCI) Implementation Science in Cancer Control Centers (ISC3) network sought to identify case examples of how Centers were applying a focus on health equity in implementation science to inform future research and capacity-building efforts.

HETF members at each ISC3 collected information on how health equity was conceptualized, operationalized, and addressed in initial research and capacity-building efforts across the seven ISC3 Centers funded in 2019–2020. Each Center completed a questionnaire assessing five health equity domains central to implementation science (e.g., community engagement; implementation science theories, models, and frameworks (TMFs); and engaging underrepresented scholars). Data generated illustrative examples from these five domains.

Centers reported a range of approaches focusing on health equity in implementation research and capacity-building efforts, including (1) engaging diverse community partners/settings in making decisions about research priorities and projects; (2) applying health equity within a single TMF applied across projects or various TMFs used in specific projects; (3) evaluating health equity in operationalizing and measuring health and implementation outcomes; (4) building capacity for health equity-focused implementation science among trainees, early career scholars, and partnering organizations; and (5) leveraging varying levels of institutional resources and efforts to engage, include, and support underrepresented scholars.

Examples of approaches to integrating health equity across the ISC3 network can inform other investigators and centers’ efforts to build capacity and infrastructure to support growth and expansion of health equity-focused implementation science.

Youth experiencing socioeconomic deprivation may be exposed to disadvantage in multiple contexts (e.g., neighborhood, family, and school). To date, however, we know little about the underlying structure of socioeconomic disadvantage, including whether the 'active ingredients' driving its robust effects are specific to one context (e.g., neighborhood) or whether the various contexts increment one another as predictors of youth outcomes.

The present study addressed this gap by examining the underlying structure of socioeconomic disadvantage across neighborhoods, families, and schools, as well as whether the various forms of disadvantage jointly predicted youth psychopathology and cognitive performance. Participants were 1,030 school-aged twin pairs from a subsample of the Michigan State University Twin Registry enriched for neighborhood disadvantage.

Two correlated factors underlay the indicators of disadvantage. Proximal disadvantage comprised familial indicators, whereas contextual disadvantage represented deprivation in the broader school and neighborhood contexts. Results from exhaustive modeling analyses indicated that proximal and contextual disadvantage incremented one another as predictors of childhood externalizing problems, disordered eating, and reading difficulties, but not internalizing symptoms.

Disadvantage within the family and disadvantage in the broader context, respectively, appear to represent distinct constructs with additive influence, carrying unique implications for multiple behavioral outcomes during middle childhood.

The emergency telephone number 9-1-1 serves as a lifeline to the public during emergencies, and first responders rely on information gathered by 9-1-1 telecommunicators who speak with callers. Timely, accurate information from the telecommunicators is essential for providing appropriate care on scene. Language barriers can hamper these efforts and result in less efficient information exchange. Although 9-1-1 telecommunicators may access over-the-phone interpreter (OPI) services to facilitate communication, managing three-way communication during an emergency is challenging.

There is little published on the relationship between limited English proficient (LEP) callers and 9-1-1 police telecommunicators, and the role of OPI services during these calls. Further, little is known about effective strategies to manage such calls.

In King County, Washington, 9-1-1 police telecommunicators were surveyed about their experiences handling LEP calls and managing three-way communication with OPI services. The survey contained 13 multiple-choice and three open-response questions addressing communication strategies, challenges with LEP callers, and three-way communication with OPI services. Goodman-Kruskal Gamma and chi-square tests were conducted with OPI use as the dependent variable. Additional analyses were conducted using stress levels as the dependent variable.

Of 123 respondents, 69 (56.5%) 9-1-1 telecommunicators reported utilizing OPI services at least 75% of the time when receiving a call from an LEP caller. Further, 35 (28.7%) of these telecommunicators reported calls with LEP individuals as more stressful than calls with fluent English speakers. Dispatcher stress level during LEP calls compared with stress during calls with fluent English speakers was positively associated with use of OPI services (P < .01). Further, stress level was also positively associated with telecommunicator difficulties in assessing the situation with respect to officer safety (P < .01). Sixty-three (58.3%) of the telecommunicators described difficulties assessing the situation to determine the appropriate response as the biggest challenge with LEP callers. Additionally, 62 (53%) identified knowing their location in English as information LEP callers need to know prior to calling 9-1-1.

These results highlight intervention opportunities for both 9-1-1 telecommunicators and LEP communities. Together, interventions such as working with LEP communities to educate them on best communication practices during 9-1-1 calls, and with 9-1-1 telecommunicators to help them manage three-way communication and reduce stress associated with concern for officer safety may improve emergency communication during 9-1-1 calls.

To develop a method to validate an FFQ for reported intake of episodically consumed foods when the reference instrument measures short-term intake, and to apply the method in a large prospective cohort.

The FFQ was evaluated in a sub-study of cohort participants who, in addition to the questionnaire, were asked to complete two non-consecutive 24 h dietary recalls (24HR). FFQ-reported intakes of twenty-nine food groups were analysed using a two-part measurement error model that allows for non-consumption on a given day, using 24HR as a reference instrument under the assumption that 24HR is unbiased for true intake at the individual level.

The National Institutes of Health–AARP Diet and Health Study, a cohort of 567 169 participants living in the USA and aged 50–71 years at baseline in 1995.

A sub-study of the cohort consisting of 2055 participants.

Estimated correlations of true and FFQ-reported energy-adjusted intakes were 0·5 or greater for most of the twenty-nine food groups evaluated, and estimated attenuation factors (a measure of bias in estimated diet–disease associations) were 0·4 or greater for most food groups.

The proposed methodology extends the class of foods and nutrients for which an FFQ can be evaluated in studies with short-term reference instruments. Although violations of the assumption that the 24HR is unbiased could be inflating some of the observed correlations and attenuation factors, results suggest that the FFQ is suitable for testing many, but not all, diet–disease hypotheses in a cohort of this size.

We evaluated the performance of the food-frequency questionnaire (FFQ) administered to participants in the US NIH–AARP (National Institutes of Health–American Association of Retired Persons) Diet and Health Study, a cohort of 566 404 persons living in the USA and aged 50–71 years at baseline in 1995.

The 124-item FFQ was evaluated within a measurement error model using two non-consecutive 24-hour dietary recalls (24HRs) as the reference.

Participants were from six states (California, Florida, Pennsylvania, New Jersey, North Carolina and Louisiana) and two metropolitan areas (Atlanta, Georgia and Detroit, Michigan).

A subgroup of the cohort consisting of 2053 individuals.

For the 26 nutrient constituents examined, estimated correlations with true intake (not energy-adjusted) ranged from 0.22 to 0.67, and attenuation factors ranged from 0.15 to 0.49. When adjusted for reported energy intake, performance improved; estimated correlations with true intake ranged from 0.36 to 0.76, and attenuation factors ranged from 0.24 to 0.68. These results compare favourably with those from other large prospective studies. However, previous biomarker-based studies suggest that, due to correlation of errors in FFQs and self-report reference instruments such as the 24HR, the correlations and attenuation factors observed in most calibration studies, including ours, tend to overestimate FFQ performance.

The performance of the FFQ in the NIH–AARP Diet and Health Study, in conjunction with the study’s large sample size and wide range of dietary intake, is likely to allow detection of moderate (≥1.8) relative risks between many energy-adjusted nutrients and common cancers.
