A Theoretically-Grounded Investigation of Perceptions About Healthy Eating and mHealth Support Among African American Men and Women in New Orleans, Louisiana

Cooking Interventions for Improving Diet Quality Among Black Americans: A Randomized Controlled Trial

BACKGROUND

Non-Hispanic Black Americans experience the highest, and most rapidly increasing, rates of obesity. Despite evidence that this is at least somewhat related to poor diet quality, we have yet to identify effective interventions for improving diet quality long-term. Restrictive diets can be ineffective and often harmful. In contrast, there is a well-established connection between home cooking and lower body mass index, better diet quality, and improved health.

PURPOSE

The present study applied the Theory of Planned Behavior (TPB) to examine the effect of an intervention delivering cooking instruction, rather than nutrition information, on beliefs, attitudes, and behaviors pertaining to diet quality and cooking among Black adults in the USA.

METHODS

An online sample of Black Americans (N = 147), ages 18-76 (M = 30.69, SD = 10.42) were recruited via Prolific and randomized to view either a cooking tutorial video or a "standard of care" control webpage followed by either an implementation intentions (II) writing activity or a "freestyle" control writing activity. Cognitions and behavior related to healthy eating and cooking were measured at baseline, post-intervention, and 1-week follow-up.

RESULTS

Results of mixed-effects modeling indicated that participants randomized to the video condition reported significantly greater post-intervention intentions to cook (p < .001), which positively correlated with cooking behavior over the subsequent week (p < .01). There was no effect of the II intervention on subsequent-week behavior (ps > .413). Importantly, 75% (n = 105) indicated experiencing food insecurity at the time of data collection.

CONCLUSIONS

These results highlight a promising pathway for improving nutrition and diet-related health outcomes among Black Americans while highlighting that any intervention must account for food insecurity in this population.

Our Voice NOLA: Leveraging a Community Engaged Citizen Science Method to Contextualize the New Orleans Food Environment

OBJECTIVE

We employed the Our Voice citizen scientist method using a mobile application (app) to identify and contextualize neighborhood-level features influencing food access and wellbeing in New Orleans, Louisiana.

DESIGN

A three-phase, multi-method study comprised of: (1) a researcher-assisted tag-a-long neighborhood walk (referred to as a 'journey') with the Discovery Tool (DT) app to document neighborhood-level features via geo-coded photos and audio-recorded narratives; (2) a post-journey interview to enable citizen scientists to share their lived experiences; and (3) a community meeting with citizen scientists and local stakeholders.

SETTING

Various neighborhoods in New Orleans, Louisiana, USA.

PARTICIPANTS

Citizen Scientists (i.e., residents) aged 18 years and older.

MAIN OUTCOME MEASURE(S)

Features that influence food access and health behaviors.

ANALYSIS

Descriptive statistics and a thematic content analysis were conducted to assess survey and app data.

RESULTS

Citizen scientists (N = 14) captured 178 photos and 184 audio narratives. Eight major themes were identified: safety; walkability; aesthetics; amenities; food; health services; neighborhood changes; and infrastructure/city planning. The post-journey interview provided insights around the abovementioned themes. The community meeting demonstrated the willingness of citizen scientists and stakeholders to convene and discuss issues and relevant solutions.

CONCLUSIONS AND IMPLICATIONS

Findings demonstrate the ability of technology and citizen science to help better understand the complexities of New Orleans' past, present and distinct culture-and implications for food access and wellbeing in the context of trauma in an urban ecosystem.

Peer Group Support Intervention to Reduce Cardiovascular Disease Risk for African American Men According to Life's Simple 7 in Faith-Based Communities

BACKGROUND AND PURPOSE

Adverse cardiovascular health disparities persist for African American men. Although changing health behaviors is perhaps one of the most effective methods to prevent cardiovascular disease (CVD)-related deaths, previous behavior change programs targeting single or multiple CVD risk factors in target groups have had mixed success. The purpose of this pilot study was to determine whether a multi-faceted peer group intervention model based on American Heart Association's Life's Simple 7 was feasible, safe, acceptable, and efficacious in producing meaningful risk reduction for African American men.

METHODS

A convenience sample of 24 African American men with at least one CVD risk factor participated quasi-experimental study having peer intervention vs. nonequivalent comparison groups, with pretest-posttests at two church sites in Minneapolis, MN (MPLS) and Washington, D.C. (DC). Feasibility, safety, acceptability, and potential efficacy were assessed by examining completion of peer group sessions, adverse events, attendance, attrition, within and between-group changes in measures using nonparametric statistics.

RESULTS

All twenty-four men completed the study with no study-related adverse symptoms and medical events. The peer groups had moderate to high attendance, and the peer program evaluation was highly positive among participants. Between baseline and 6-months, there were significant differences between the intervention and the comparison group in cholesterol levels and weights (p = .041, p = .034, respectively) at one site (DC). There were no significant between-group changes at the other site (MPLS).

IMPLICATION FOR PRACTICE

The multi-faceted peer support intervention was feasible, acceptable, and shown to have potential efficacy to reduce CVD risk for highly motivated African American men. Future studies with a larger sample size are needed to test the effectiveness of this intervention model to reduce CVD risk among African American men.

Delivering Health Information to Parents via a Theory-Informed SMS-Based Intervention: Development and Results from a Pilot Study

INTRODUCTION

Short message service (SMS), or text-based, health interventions offer a promising opportunity to deliver health education and have been shown to improve diet and exercise. However, few are theory-based or target low-income parents. This pilot study, informed by the Theory of Planned Behavior (TPB), primarily sought to determine if health education delivered via SMS was feasible and acceptable to low-income parents of young children.

METHODS

Using a one-group, pre- to post-test study design to assess a 12-week SMS-based health education program, parents enrolled in a health-related program at an early childhood development center for low-income families were sent three text messages per week that corresponded to a weekly diet or physical activity-related theme. Surveys assessed pre-post changes in TPB constructs and collected program feedback.

RESULTS

Among the 119 eligible parents invited to participate, 109 were sent all text messages for the duration of the study. Participants were mostly Black (98.9%), 25-39 years old (83.9%), female (93.8%), and in single-parent households (63.8%). More than half (n = 59) completed the pre-survey, answered a bi-directional program text, or completed the post-survey. Twelve participants completed both the pre- and post-survey and at least one bi-directional text. Post-survey results revealed that most participants liked the program design and enjoyed their experience with the program.

CONCLUSIONS

SMS-based interventions can simplify delivery of health information to low-income parents of young children. Although engagement was low, retention was high, and feedback was largely positive.

Early Perceptions of COVID-19 Contact Tracing Apps in German-Speaking Countries: Comparative Mixed Methods Study

Background

The main German-speaking countries (Germany, Austria, and Switzerland) have implemented digital contact tracing apps to assist the authorities with COVID-19 containment strategies. Low user rates for these apps can affect contact tracing and, thus, its usefulness in controlling the spread of the novel coronavirus.

Objective

This study aimed to assess the early perceptions of people living in the German-speaking countries and compare them with the frames portrayed in the newspapers during the first wave of the COVID-19 pandemic.

Methods

We conducted qualitative interviews with 159 participants of the SolPan project. Of those, 110 participants discussed contact tracing apps and were included in this study. We analyzed articles regarding contact tracing apps from 12 newspapers in the German-speaking countries.

Results

Study participants perceived and newspaper coverage in all German-speaking countries framed contact tracing apps as governmental surveillance tools and embedded them in a broader context of technological surveillance. Participants identified trust in authorities, respect of individual privacy, voluntariness, and temporary use of contact tracing apps as prerequisites for democratic compatibility. Newspapers commonly referenced the use of such apps in Asian countries, emphasizing the differences in privacy regulation among these countries.

Conclusions

The uptake of digital contact tracing apps in German-speaking countries may be undermined due to privacy risks that are not compensated by potential benefits and are rooted in a deeper skepticism towards digital tools. When authorities plan to implement new digital tools and practices in the future, they should be very transparent and proactive in communicating their objectives and the role of the technology—and how it differs from other, possibly similar, tools. It is also important to publicly address ethical, legal, and social issues related to such technologies prior to their launch.

A Cardiovascular Health and Wellness Mobile Health Intervention Among Church-Going African Americans: Formative Evaluation of the FAITH! App

BACKGROUND

In light of the scarcity of culturally tailored mobile health (mHealth) lifestyle interventions for African Americans, we designed and pilot tested the Fostering African-American Improvement in Total Health (FAITH!) App in a community-based participatory research partnership with African American churches to promote cardiovascular health and wellness in this population.

OBJECTIVE

This report presents the results of a formative evaluation of the FAITH! App from participants in an intervention pilot study.

METHODS

We included 2 semistructured focus groups (n=4 and n=5) to explore participants' views on app functionality, utility, and satisfaction as well as its impact on healthy lifestyle change. Sessions were audio-recorded and transcribed verbatim, and qualitative data were analyzed by using general inductive analysis to generate themes.

RESULTS

In total, 6 overarching themes emerged among the 9 participants: overall impression, content usefulness, formatting, implementation, impact, and suggestions for improvement. Underpinning the themes was a high level of agreement that the intervention facilitated healthy behavioral change through cultural tailoring, multimedia education modules, and social networking. Suggestions for improvement were streamlining the app self-monitoring features, prompts to encourage app use, and personalization based on individuals' cardiovascular risk.

CONCLUSIONS

This formative evaluation found that the FAITH! App had high reported satisfaction and impact on the health-promoting behaviors of African Americans, thereby improving their overall cardiovascular health. Further development and testing of the app among African Americans is warranted.

Time to listen: a mixed-method study examining community-based views of mobile technology for interventions to promote physical activity

INTRODUCTION

A mixed-method, co-design approach to studying the adoption of mobile health (mHealth) technology among African-American (AA) women has not been fully explored. Qualitative data may contextualise existing knowledge surrounding perceptions of mHealth among AA women as part of formative work for designing a physical activity application (app).

METHODS

A convenience sample of 16 AA women completed an informatics survey prior to participating in focus groups exploring their use of mobile technology and health apps. Survey responses provided frequency data, while iterative transcript analysis of focus groups identified themes.

RESULTS

The majority of participants (mean age=62.1 years, SD=6.6) felt comfortable using a tablet/smartphone (75.0%). Most (68.8%) reported using health-related apps, primarily focused on physical activity and nutrition. Focus groups revealed four overarching concepts, including (1) user attachment, (2) technology adoption, (3) potential facilitators and (4) potential barriers. Important features which may serve as facilitators or barriers to future adoption of a mobile app for an mHealth intervention include individual app tailoring and software concerns, respectively.

DISCUSSION

Thematic analysis revealed high user attachment to smartphones and described participants' process for adopting new mHealth technology.

CONCLUSION

Early engagement of target end users as a part of a broader co-design and community-based participatory research process for developing mHealth technologies may be useful for sustained adoption of these tools in future mHealth behavioural interventions.

Romain J, Jerrod T, Griffith DM, Myers V. Development of a mobile phone app to maintain physical activity in African American men: MobileMen

BACKGROUND

African American men experience health disparities across a number of chronic diseases. mHealth technology is widely utilized to address lifestyle factors that contribute to these conditions. Participation of African American men in qualitative and quantitative studies of mHealth is low. Therefore, little is known regarding the acceptability of mHealth interventions and few interventions have been specifically developed for this population. The purpose of the current study is to describe the development of a smartphone application, MobileMen, to promote the maintenance of physical activity (PA) in African American men and to report on app feasibility when applied to the target population.

METHODS

We used a mixed methods study design including formative research, user-centered design, and a feasibility study. Focus groups (n=26) were conducted to inform the acceptability of the app and desired features. Lab usability (n=19) was used to develop the app through an iterative process. A feasibility study was conducted to assess utilization of the app over a 1-month timeframe. Measures of usability and user-friendliness were collected during lab usability sessions. Satisfaction and app usage were collected following the feasibility study.

RESULTS

The focus groups revealed that African American men use smartphone apps and that they are willing to utilize an app to maintain PA habits. The MobileMen app was subsequently developed and contained a dashboard, rewards, a learning component, a prompting system, and activity tracking. Scores increased between the first and last lab sessions for usability [5.0 (0.0) vs. 4.3 (1.0)] and user-friendliness [74.2 (17.0) vs. 70.6 (12.4)]. Participants reported acceptable satisfaction (mean values >3.5 on a 1-5 Likert scale) with most app components.

CONCLUSIONS

African American men are willing to utilize mHealth to improve their health behavior, including PA. An initial version of the MobileMen app has been developed that is acceptable and user-friendly. However, there are several components requested by African American men could not be included in the current app but warrant future app development.
