RESUMO
BACKGROUND: This study reports on the development of pictorial health warning labels for electronic nicotine delivery system (ENDS) using the Delphi approach with a panel of tobacco control experts. Twenty-four evidence-based ENDS-specific warnings corresponding to three themes (toxicity, health risks and specific harm) were developed and used in the Delphi study. METHODS: We conducted a three-round online Delphi study among 60 experts (55% female) between June 2022 and April 2023. We balanced the panel in areas of expertise and positions relevant to ENDS (risks, benefits). In round 1, participants rated the warnings on attention, relevance to evidence and perceived effectiveness (harm perception, motivation to quit) and provided suggestions for improvement. In rounds 2 and 3, participants ranked the revised warnings based on importance in each theme. We assessed levels of agreement between participants using interquartile deviations and medians. RESULTS: Warnings in theme 1, toxicity, received the highest ratings for perceived effectiveness on harm perception and encouraging quitting ENDS (p<0.05). Experts recommended using clear and affirmative text paired with emotion-provoking pictures and avoiding the rare side effects of ENDS. Most of the top-ranked warnings were from theme 3, ENDS-specific harm, pertained to lung damage, dual use of ENDS and cigarettes, nicotine addiction among youth, anti-ENDS industry sentiment and toxicity. DISCUSSION: This study developed 24 evidence-based ENDS health warning labels using a systematic process that included several rounds of expert panel feedback. These warnings can be used to advance ENDS prevention and tobacco control policies and further target different populations.
RESUMO
Childhood obesity is a public health threat that disproportionally affects Latino youth in the United States. Active and Healthy Families (AHF) is a culturally tailored, family-based program for addressing obesity disparities in a predominantly immigrant Latino population. AHF was the first primary care, culturally tailored intervention for Latino children to significantly reduce BMI in a randomized controlled trial. The 10-week AHF intervention reduced BMI (kg/m2) among overweight or obese children by 0.5, compared with an increase of 0.3 in the control group, yielding a -0.8 difference ( p < .01). A unique aspect of the program is its provider team: a physician, dietitian, and promotora. Because early feedback from families highlighted the importance of promotoras specifically, we sought to understand the unique mechanisms of promotora effectiveness in AHF. We conducted in-depth, semistructured interviews with the AHF providers ( n = 5) and parent participants ( n = 23) by phone between November 2012 and May 2013. In a grounded theory analysis, three main categories encompassing five themes emerged: (a) bridging communication by promotoras; (b) promotoras' personal qualities, including themes of kindness and caring and shared experiences with patients; and (c) impactful task performance, including themes of motivation, positive environment, and self-efficacy. Together, the themes serve as the basis of a conceptual model illustrating the process through which promotoras may enhance the impact of team-based obesity programs for the Latino community. Because this study identifies the specific ways through which promotoras can bridge cultural, linguistic, and other divides, it may inform development and dissemination of evidence-based approaches for obesity prevention in the Latino community.
