Introduction: Church-based interventions have been shown to improve the dietary health of underserved populations, yet few studies have examined sustainability of health behavior change over time. This paper examines dietary outcomes over a 24-month period (baseline and 6, 18, and 24 months) for fruit and vegetable and fat consumption behaviors of African-American participants in the Health for Hearts United church-based intervention in North Florida.Study Design: This quasi-experimental, longitudinal trial was conducted from 2009 to 2012. Data were analyzed in 2018.Setting/participants: Six churches in a 2-county area (3 treatment, 3 comparison) were selected for the study using community-based participatory research approaches. Participants were African-American adults (aged ≥45 years; n=211 at baseline) randomly selected from the churches, stratified by age and sex.Intervention: Health for Hearts United intervention was developed by the 3 treatment churches. The 18-month intervention was implemented in 3 6-month phases, framed around 3 conceptual components, which included 4 types of programs and 4 key messages.Main Outcome Measures: Fruit and vegetable consumption was assessed using a single item (fruit and vegetable intake) and the National Cancer Institute Fruit and Vegetable Screener. Fat consumption was determined using a single item (fat intake) and the National Cancer Institute Fat Screener. Background characteristics included age, sex, educational level, and marital status.Results: Significant time effects only were found for daily fruit and vegetable intake (p<0.001), fat intake (p<0.001), and the Fat Screener (p<0.001) with dietary improvements in both treatment and comparison groups across the intervention phases. Fruit and Vegetable Screener results showed that time (p<0.001) and the interaction between time and treatment (p<0.01) were significant, with increases in fruit and vegetable consumption over time for both the treatment and comparison groups and with the increase differing between groups. Post hoc analysis revealed that the treatment group had greater increases in fruit and vegetable consumption than the comparison group between Phases 1 and 3 (p=0.03).Conclusions: Dietary behaviors of mid-life and older African Americans can be improved and sustained over 24 months using a church-based heart health intervention, with similar improvements noted for both comparison and treatment participants.Trial Registration: This study is registered at www.clinicaltrials.govNCT03339050.

Home visitation programs offer a unique opportunity to implement a novel digital early childhood obesity prevention program. Evaluate usability of a digital infant feeding nutrition education module with key stakeholders (N=21) of a home visiting program in Florida. Home visitors (n=11) and enrolled mothers (n=10) of a home visiting program in Florida participated in a one-time, 45-minute qualitative interview via Zoom with a trained researcher using a semi-structured script based on constructs from the Technology Acceptance Model (TAM) and Social Cognitive Theory (SCT). Participants also completed a modified version of the mHealth App Usability Questionnaire (MAUQ). Interviews were audio-recorded, deidentified, transcribed verbatim and coded by two trained researchers using an inductive thematic analysis approach based on TAM and SCT constructs to develop themes. MAUQ subscales were analyzed using descriptive statistics. Most participants noted that they liked the digital format, and specifically mentioned the visual or interactive components, convenience and accessibility of the information, and general preference for digital information over paper handouts. Home visitors were interested in content related to food allergies and readiness for solid foods, whereas mothers were interested in all of the infant feeding topics. Nonetheless, the majority (90%) reported that they would be very likely to use information in the learning modules as part of home visits. Usability of the module was high across all three MAUQ subscales (mean ratings out of 7±SD: ease of use = 6.88±0.2, interface and satisfaction = 6.90±0.4, usefulness = 6.78±0.1). Limited access to technology by parents, compatibility of the module with various phone types, and necessity of keeping information updated were mentioned by home visitors as limitations that may impact usability. The results revealed that a digital nutrition education module to prevent early childhood obesity was deemed usable by both staff and parents of a home visiting program. Future research is needed to determine impact on parental feeding behaviors and child health outcomes. University of Florida Mowery Innovative Research Fund [ABSTRACT FROM AUTHOR]

Aims: In recent years, studies have indicated that consumers of alcohol mixed with energy drink (AmED) are more likely to drink heavily and experience more negative consequences than consumers who avoid these beverages. Although researchers have identified a number of plausible hypotheses that explain how alcohol-energy drink co-ingestion could cause greater alcohol consumption, there has been no postulation about reverse causal relations. This paper identifies several plausible hypotheses for the observed associations between AmED consumption and greater alcohol consumption, and provides initial evidence for one such hypothesis suggesting that heavy drinking may be a determinant of AmED use.Method: Data collected from 511bar patrons were used to examine the plausibility of one of the proposed hypotheses, i.e., AmED is an artifact of heavy drinking. Associations between the consumption of an assortment of alcoholic beverage types and total alcohol consumption were examined at the event-level, to assess whether AmED is uniquely related with greater alcohol consumption.Results: Increased alcohol consumption was associated with greater odds of consuming most alcoholic beverage types; this association was not unique to AmED.Conclusions: Results support the overlooked hypothesis that AmED use is an artifact of heavy drinking. Thus, AmED consumption may be a consequence or marker of heavier drinking. Much of the existing research on alcoholic beverage types is limited in its ability to implicate any specific type of drink, including AmED, as a cause of increased alcohol consumption and related harm. More rigorous study designs are needed to examine causal relationships. [ABSTRACT FROM AUTHOR]

Introduction: Technology has transformed our lifestyles in dramatic and significant ways, including new and less expensive options for recruiting study participants. This study examines cost and participant differences between two recruitment sources, Craigslist (CL), and print newspapers (PNs). This paper also reviewed and compared studies involving clinical trials published since 2010 that recruited participants using CL alone or in combination with other methods.Method: Secondary data analyses from a parent study involving a randomized controlled trial of a mail-based intervention to promote self-change with problem drinkers.Results: Significant differences were found between CL and PN participants on most demographic and pretreatment drinking variables. While all participants had AUDIT scores suggestive of an alcohol problem and reported drinking at high-risk levels, CL participants had less severe drinking problem histories, were considerably younger, and had a higher socioeconomic status than PN participants. The total advertising costs for the 65 CL ads ($275) were significantly less than the 69 PN ads ($33, 311). The recruiting cost per eligible participant was vastly less expensive using CL ($1.46) compared to print newspaper ads ($116.88).Conclusions: Using CL is a viable recruitment method for soliciting participants, particularly those that are younger, for alcohol intervention studies. It is also less expensive than newspaper ads. When CL participants were recruited, they reported being slightly more confident to change their drinking than PN participants. Limitations of using CL are discussed, including that some initial ad responders gave inconsistent answers to similar questions and a few tried to enter the study more than once.
