Results from "Live Well", a randomized controlled community-based participatory intervention to prevent obesity in new immigrant mother-child dyads.

Background: Upon arrival, the prevalence of overweight and obesity is lower in new immigrants than their native counterparts in the U.S. With longer residency in the U.

Improving the experience in the pedestrian's interaction with an autonomous vehicle: An ergonomic comparison of external HMI.

The number of studies on autonomous vehicles has increased over recent years. Many of these studies have indicated the importance of an external Human-Machine Interface of communication (eHMI) on autonomous vehicles to indicate their intentions to other road users. Using an experimental design, we compared three eHMIs coupled to three road infrastructures to observe pedestrians' crossing behavior and collect their feelings about different vehicle types.

Effect of Prior Health Knowledge on the Usability of Two Home Medical Devices: Usability Study.

Background: Studies on the usability of health care devices are becoming more common, although usability standards are not necessarily specified and followed. Yet, there is little knowledge about the impact of the context of use on the usability outcome. It is specified in the usability standard (ISO 9241-11, 2018) of a device that it may be affected by its context of use and especially by the characteristics of its users.

Recruitment of New Immigrants Into a Randomized Controlled Prevention Trial: The Live Well Experience.

Minority populations are hard to reach with prevention interventions because of cultural and logistical barriers to recruitment. Understanding how to overcome these barriers is pertinent to reducing the elevated burden of obesity within these underserved communities. To inform this literature gap, we explore the processes and outcomes of recruitment for Live Well-a randomized controlled obesity prevention intervention targeting new immigrant mothers and children from Brazil, Latin America, and Haiti who were residing in the greater Somerville, MA area.

Improving heart health among Black/African American women using civic engagement: a pilot study.

Background: Despite increased risk for cardiovascular disease (CVD) and related conditions, evaluations of health interventions indicate that Black/African American women are less likely to benefit than their white counterparts and are not as likely to engage in behaviors that reduce CVD risk. The purpose of this study was to test the feasibility and effectiveness of civic engagement as an intervention strategy to address heart health in Black/African American women.

Methods: Using a quasi-experimental pre-post study design, civic engagement was tested by convening a convenience sample of self-identified Black/African American women, ages 30-70 years, English-speaking, and BMI ≥25.
