ObjectiveWe built an app to help clients of food pantries. The app offers vegetable-based recipes, food tips and no-cost strategies for making mealtimes healthier and for bargain-conscious grocery shopping, among other themes. Users customize materials to meet their own preferences. The app, available in English and Spanish, has been tested in a randomized field trial.DesignA randomized controlled trial with repeated measures across 10 weeks.SettingClients of fifteen community food pantry distributions in Los Angeles County, USA.ParticipantsDistributions were randomized to control and experimental conditions, and 289 household cooks and one of their 9–14-year-old children were enrolled as participants. Experimental dyads were given a smartphone with our app and a phone use-plan, then trained to use the app. ‘Test vegetables’ were added to the foods that both control and experimental participants received at their pantries.ResultsAfter 3–4 weeks of additional ‘test vegetables’, cooks at experimental pantries had made 38 % more preparations with these items than control cooks (P = 0·03). Ten weeks following baseline, experimental pantries also scored greater gains in using a wider assortment of vegetables than control pantries (P = 0·003). Use of the app increased between mid-experiment and final measurement (P = 0·0001).ConclusionsThe app appears to encourage household cooks to try new preparation methods and widen their incorporation of vegetables into family diets. Further research is needed to identify specific app features that contributed most to outcomes and to test ways in which to disseminate the app widely.
Despite the availability of safe, effective COVID-19 vaccines, many remain unvaccinated or partially vaccinated. In 2021, the California Department of Public Health launched a California-wide integrated multicultural vaccine media campaign. The campaign was evaluated in two waves through online surveys with adults (n = 1594; n = 1575). Campaign exposure was associated with looking for vaccine information, visiting a state vaccine Web site, and becoming fully vaccinated during the campaign. Higher campaign exposure was associated with greater odds of vaccine engagement. (Am J Public Health. Published online ahead of print August 11, 2022:e1–e5. https://doi.org/10.2105/AJPH.2022.306974 )
Background This study describes the development and impact of a social marketing campaign in early 2020 intended to prevent and reduce methamphetamine use in Los Angeles County (LAC). We used social marketing principles and the transtheoretical model to design the campaign, which was intended to avoid stigmatization of methamphetamine users and communicate compassion, empathy, and support. Methods To evaluate its impact, we collected cross-sectional online survey data post-campaign (n = 1,873) from LAC residents in population segments considered higher risk for methamphetamine use. We examine associations between campaign exposure and outcomes using bivariate analyses and binary logistic regression models, which control for the impact of the COVID-19 pandemic on methamphetamine use or likelihood of use. Results The analyses revealed that campaign exposure was associated with having more negative attitudes toward methamphetamine, calling LAC’s substance abuse service helpline, using methamphetamine fewer days, and considering abstaining. Frequency of exposure to campaign advertisements was positively associated with calling the helpline, suggesting a campaign dose effect. COVID-19-related factors were associated with using methamphetamine in the past 30 days. Conclusions Social marketing campaigns hold promise for impacting methamphetamine prevention and cessation behaviors. This study adds to the limited literature on mass marketing interventions to address this major health issue.
Objectives: Latino families are among the most likely to be overweight or obese, which are conditions associated with numerous health risks and diseases. These families might lack know-how for preparing vegetables that fall outside cooks’ culinary comfort zones and cultural traditions. Mobile apps are increasingly being developed for healthier cooking and eating, but research has not much explored how such apps are used among these families to help facilitate changes in eating patterns. This research seeks to identify behaviors and motivations that lead household cooks (i.e. mothers) in low-income Latino homes to use a food and nutrition app and create healthier eating environments for their families. Methods: This study uses a positive deviance approach and individual interviews with mothers who were frequent app users and experienced beneficial food outcomes during their participation in a randomized controlled trial that tested the effects of an app on their cooking and family eating behaviors. Interviews were analyzed for themes using a framework analysis approach. Results: Three themes emerged across interviews that were suggestive of approaches that led mothers to become frequent app users and prepare healthier meals: (1) mothers invited their children to use the app; (2) they involved both sons and daughters in the kitchen; and (3) they (cautiously) stepped outside their culinary comfort zones. Conclusion: Mobile apps and app-focused interventions should include features that invite: app co-use between mothers and children; opportunities for mothers to socialize boys, as well as girls into kitchen routines; and the use of culturally-familiar ingredients or recipes that are easily adaptable.
Background Adolescents in Mexico experience high pregnancy and birth rates. A collaboration with Grupo Televisa led to the development of an entertainment-education telenovela intervention, Overcome the Fear (OTF), which aired in 2020 to a national audience and addressed adolescent sexual and reproductive health (SRH) topics. This study details the development and evaluation of OTF’s impact on adolescent contraceptive practices and parent-adolescent SRH communication in Mexico. Methods We conducted cross-sectional survey interviews (street-intercept and telephone) with 12–19-year-olds (n = 1640) and parents of adolescent children (n = 820) post-broadcast across Mexico’s five most-populated metropolitan zones. Quotas were implemented for gender, zone, and OTF viewership (viewer vs. non-viewer). Bivariate statistics and multivariable binary logistic regression models assessed the relationship between OTF viewership (including parent-adolescent co-viewing) and adolescent contraceptive practices and parent-adolescent SRH communication. Adolescent and parent data are not dyadic and were analyzed separately. Results Nearly half of adolescents (47.9%) and parents (47.7%) were viewers. Among adolescents, bivariate analyses suggest that viewers had less negative attitudes towards contraception (p < .001). Logistic regression models suggest that adolescent viewers were more likely to seek out information about contraception (p < .001) and unhealthy romantic relationships (p = .019), and to use contraception other than condoms (p = .027) and dual contraception (p = .042) in the last 3 months. Among parents, bivariate analyses suggest that non-viewers had more positive attitudes towards abstinence (p = .045) and more negative attitudes towards contraception and communication with adolescents about sex (p = .001). Logistic regression models suggest that parent viewers were more likely to have talked with adolescent children about sexual relations (p < .001), contraceptive methods (p = .01), condoms (p = .002), and abstinence (p = .002) in the last 3 months. Parent-adolescent co-viewing of OTF was also significantly related to certain outcomes in bivariate analyses. Conclusions This study suggests that viewership of a high-quality entertainment-education telenovela informed by extensive formative research is related to adolescent health outcomes and to parent-adolescent SRH communication on a country-wide scale in Mexico. Entertainment-education remains an underutilized public health strategy, despite its promise to engage viewers and motivate healthful behaviors.
