RESUMO

BACKGROUND: Aguas frescas are Mexican drinks that are typically made with water, sugar, and fruit. Aguas frescas may be a significant component of sugary-drink intake among Mexican and Mexican-American (MA) adults. However, it is unclear whether survey respondents report aguas frescas consumption when it is not specifically queried in standardized beverage frequency instruments. OBJECTIVES: This study examined the prevalence of aguas frescas consumption, the sociodemographic correlates of aguas frescas intake, and how specifically querying aguas frescas intake affects sugary-drink estimates among Mexican and MA adults. METHODS: Cross-sectional, online surveys were conducted in 2021 with 5377 Mexican and 3073 MA adults as part of the International Food Policy Study. Past 7-d consumption of sugar-sweetened beverages (SSBs), sugary drinks, and aguas frescas were assessed along with relevant covariates. Weighted analyses included logistic and linear regression, including models with correlation structure. RESULTS: An estimated 61.7% of Mexican and 28.7% of MA adults consumed aguas frescas. In Mexico, consumption was associated with females, low education, perceiving oneself as having about the right weight, being good to excellent health, and consuming an unhealthy amount of sugary drinks. For MAs, intake was associated with being younger, speaking Spanish, and perceiving oneself as being underweight or about the right weight. Among Mexican adults who consumed aguas frescas but did not report them unless specifically queried, the volume of SSB intake was 67.9% higher for females and 64.3% higher for males when aguas frescas were included. Among MAs, SSB intake was 56.9% higher for females and 44.1% higher for males. Most participants (79.9%-85.2%) remained in the same sugary-drink tertiles when including compared with excluding aguas frescas. CONCLUSIONS: Aguas frescas should be queried during beverage intake assessments, as they contribute a nontrivial amount of added sugars to the diets of many Mexican and MA adults.

RESUMO

OBJECTIVE: In 2020, Mexico implemented innovative front-of-package nutrition warning labels (FoPWLs) for packaged foods to increase the salience and understanding of nutrition information. This study evaluated Mexican Americans' self-reported exposure to Mexican FoPWLs and self-reported effects of FoPWLs on purchasing behavior. METHODS: The 2021 International Food Policy Study surveyed online panels of adult Mexican Americans in the US (n = 3361) to self-report on buying food at Mexican-oriented stores, noticing Mexican FoPWLs, and being influenced by FoPWLs to purchase less of eight different unhealthy foods (each assessed separately). After recoding the frequency of buying foods in Mexican stores and noticing FoPWLs (i.e., "often" or "very often" vs. less often), logistic models regressed these outcomes on sociodemographics, adjusting for post-stratification weights. RESULTS: Most participants (88.0%) purchased foods in Mexican stores. Of these, 64.1% reported noticing FoPWLs, among whom many reported that FoPWLs influenced them to buy fewer unhealthy foods (range = 32% [snacks like chips] - 44% [colas]). Participants were more likely to buy foods in Mexican stores and notice FoPWLs if they were younger, had ≥two children at home vs no children (AOR = 1.40, 95%CI = 1.15-1.71; AOR = 1.37, 95%CI = 1.03-1.80, respectively), and more frequently used Spanish (AOR = 1.91, 95%CI = 1.77-2.07; AOR = 1.87, 95%CI = 1.69-2.07). Also, high vs. low education (AOR = 1.51, 95%CI = 1.17-1.94) and higher income adequacy (AOR = 1.37, 95%CI = 1.25-1.51) were positively associated with noticing FoPWLs. Being female and more frequent Spanish use were consistently associated with reporting purchase of fewer unhealthy foods because of FoPWLs. CONCLUSIONS: Many Mexican Americans report both exposure to Mexican FOPWLs and reducing purchases of unhealthy foods because of them.

RESUMO

In this article, we examine progress and challenges in designing, implementing, and evaluating culturally sensitive behavioral interventions by tailoring health communication to groups or individuals. After defining common tailoring constructs (i.e., culture, race, and ethnicity), cultural sensitivity, and cultural tailoring, we examine when it is useful to culturally tailor and address cultural sensitivity in health communication by group tailoring or individual tailoring and when tailoring health communication may not be necessary or appropriate for achieving behavior change. After reviewing selected approaches to cultural tailoring, we critique the quality of research in this domain with a focus on the internal validity of empirical findings. Then we explore the ways in which cultural sensitivity, group targeting, and individual tailoring have incorporated culture in health promotion and health communication. We conclude by articulating yet unanswered questions and suggesting future directions to move the field forward. Expected final online publication date for the Annual Review of Public Health, Volume 45 is April 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

RESUMO

OBJECTIVE: Front-of-package warning labels introduced in Mexico in 2020 included disclaimers that caution against allowing children to consume products with non-sugary sweeteners and caffeine. We examined the awareness and use of the disclaimers among Mexican adults and youth 1 month after the regulation was implemented. We also investigated their impact on the perceived healthfulness of industrialised beverages designed for children. DESIGN: Data on the awareness and use of the disclaimers were analysed. Two between-subjects experiments examined the effect of a sweetener disclaimer (Experiment 1, youth and adults) or a caffeine disclaimer (Experiment 2, only adults) on the perceived healthfulness of industrialised beverages. Interactions between experimental conditions and demographic characteristics were tested. SETTING: Online survey in 2020. PARTICIPANTS: Mexican adults (≥18 years, n 2108) and youth (10-17 years, n 1790). RESULTS: Most participants (>80 %) had seen the disclaimers at least rarely, and over 60 % used them sometimes or frequently. The sweetener disclaimer led to a lower perceived healthfulness of a fruit drink (adults: 2·74 ± 1·44; youth: 2·04 ± 0·96) compared with the no-disclaimer condition (adults: 3·17 ± 1·54; youth: 2·32 ± 0·96) (t's: >4·0, P values: <0·001). This effect was larger among older adults and male youth. The caffeine disclaimer did not affect adult's perceived healthfulness of a caffeinated drink (t = 0·861, P value = 0·3894). CONCLUSIONS: There were high awareness and use of the sweeteners and caffeine disclaimers shortly after the warning labels were implemented. The sweetener disclaimer appears to be helping consumers modify their perceptions regarding industrialised beverages for children. Findings may help decision-makers improve the regulation and better target communication strategies.

RESUMO

Few studies have compared the effects of different front-of-package label (FOPL) systems in the 'real world'. This study assessed adults' awareness, use and understanding of nutrition facts labels (NFLs) and nationally implemented FOPLs such as Health Star Ratings (HSR), Traffic lights, and Guideline Daily Amounts (GDAs) in five countries, including before and after implementation of Mexico's warning FOPLs in 2020. Data were from the International Food Policy Study, an annual repeat cross-sectional study conducted in 2018-2020 among adults (N=64,032) in Australia, Canada, Mexico, the UK and the US. Self-reported awareness, use, and understanding of NFLs (in all five countries) and FOPLs (in Australia, Mexico, and UK) were assessed over time, between countries, and between NFLs and FOPLs. Most respondents in all countries reported seeing their country's NFLs (awareness) 'often' or 'all the time' across all three years, with one third to half of respondents using NFLs 'often' or 'all the time' (Australia: 43-45%; Canada: 47-50%; Mexico: 36-39%; UK: 32-34%; US: 47-49%), and approximately one half to two thirds finding NFLs 'easy' or 'very easy to understand' (56-57%; 67-69%; 51-54%; 48-51%; 70-71%). In 2020, awareness, use and self-reported understanding of the Warning FOPLs in Mexico were highest among all countries with a FOPL (p<0.001), whereas awareness and use were lowest for Australia's HSR (p<0.001). In countries with FOPLs, self-reported understanding was higher for FOPLs than NFLs, except for the GDA FOPL in Mexico. Only modest changes were observed over time. Warning FOPLs were associated with greater levels of self-reported awareness, use and understanding among adults compared to NFLs and GDA-based FOPLs. FOPLs implemented on a voluntary basis, such as Australia's HSR, may be less likely to be seen and used.

RESUMO

OBJECTIVES: Although links between social relationships and health are well established, few studies have concurrently examined the effects of compositional, structural, and functional dimensions of social networks on glycemic (HbA1c) control in low- and middle-income countries such as Ghana. In these settings where informal social relationships are critical for access to resources, evaluating the links between social network characteristics, social support, and glycemic control may provide clarity about important relationships that facilitate the well-being of individuals with type 2 diabetes mellitus (T2DM). DESIGN: In 2018, we conducted a hospital-based, cross-sectional survey of noninstitutionalized adults with T2DM in Ghana. Using data from 247 study participants, multivariable linear regression models were used to estimate associations between: 1) HbA1c and three social network characteristics (kin composition, household composition, and network density); 2) social support and the three social network characteristics; and 3) HbA1c and social support. We also examined gender differences in these associations and applied mediation techniques to determine if network characteristics operated through social support to affect HbA1c. RESULTS: Findings indicated that higher kin composition and higher household composition were each significantly associated with increased social support. Neither social support nor social network characteristics were significantly related to HbA1c, and there were no gender differences in any of these associations. CONCLUSION: Although family and household members were identified as important sources of social support for diabetes management, the ways in which they influence HbA1c control among Ghanaians require further investigation. Future studies can examine whether changes in social support over time, social support satisfaction, or other dimensions of social relationships improve T2DM outcomes in countries like Ghana.

RESUMO

BACKGROUND: Stigma is a formidable burden for survivors of lung cancer that can reduce the quality of life (QOL), resulting in physical, social and psychological challenges. This study investigates associations between stigma and depression, QOL and demographic and health-related characteristics, including race. DESIGN: An adapted conceptual model derived from the Cataldo Lung Cancer Stigma Scale guided this descriptive correlation study assessing stigma in African American and Caucasian survivors of lung cancer. Self-reported, written surveys measuring depression, QOL, lung cancer stigma and demographics were administered. Statistical analysis was conducted to assess associations between stigma and depression, stigma and QOL and stigma and race, while adjusting for demographic characteristics. RESULTS: Participants (N = 56) included 30 Caucasian and 26 African American survivors of lung cancer recruited from a cancer registry of an American College of Surgeons-accredited programme, a survivors' support club and an ambulatory oncology practice in the southeastern United States. Statistical analysis yielded (1) a significant moderate positive association between depression and lung cancer stigma; (2) a significant moderate negative association between QOL and lung cancer stigma; and (3) significant relationships between race and lung cancer stigma, specifically higher degree of stigma among African Americans compared to Caucasians. CONCLUSION: Stigma affects many aspects of survivors' lives. Healthcare professionals need to consider how health-related stigma may further complicate the physical burdens, psychological distresses and social challenges that accompany the disease, especially among African American survivors. Additional enquiry and interventions are needed to assist with mitigating the negative effects of stigma on survivors and their family members and friends. PATIENT OR PUBLIC CONTRIBUTION: Fifty-six survivors of lung cancer participated in this descriptivecorrelation study. They completed written surveys measuring depression, QOL, and lung cancer stigma, plus an investigator-developed demographic information form.

RESUMO

This study examined whether the frequency of participation in religious activities and seeking care from spiritual and other traditional medicine (TM) practitioners were associated with blood glucose (HbA1c) control among urban Ghanaians with type 2 diabetes mellitus (T2DM). Findings revealed that increased frequency of participation in religious activities was significantly associated with decreased HbA1c levels, whereas increased use of TM practitioners was significantly associated with increased HbA1c levels. These findings suggest that strategically integrating religious activities into disease management plans for Ghanaians with T2DM who identify as being religious may be a viable intervention mechanism.

RESUMO

The 90 kDa heat shock protein (Hsp90) is a molecular chaperone that processes nascent polypeptides into their biologically active conformations. Many of these proteins contribute to the progression of cancer, and consequently, inhibition of the Hsp90 protein folding machinery represents an innovative approach toward cancer chemotherapy. However, clinical trials with Hsp90 N-terminal inhibitors have encountered deleterious side effects and toxicities, which appear to result from the pan-inhibition of all four Hsp90 isoforms. Therefore, the development of isoform-selective Hsp90 inhibitors is sought to delineate the pathological role played by each isoform. Herein, we describe a structure-based approach that was used to design the first Hsp90α-selective inhibitors, which exhibit >50-fold selectivity versus other Hsp90 isoforms.

RESUMO

Heat shock protein 90 (Hsp90) is a eukaryotic chaperone responsible for the folding and functional activation of numerous client proteins, many of which are oncoproteins. Thus, Hsp90 inhibition has been intensely pursued, resulting in the development of many potential Hsp90 inhibitors, not all of which are well-characterized. Hsp90 inhibitors not only abrogate its chaperone functions, but also could help us gain insight into the structure-function relationship of this chaperone. Here, using biochemical and cell-based assays along with isothermal titration calorimetry, we investigate KU-32, a derivative of the Hsp90 inhibitor novobiocin (NB), for its ability to modulate Hsp90 chaperone function. Although NB and KU-32 differ only slightly in structure, we found that upon binding, they induce completely opposite conformational changes in Hsp90. We observed that NB and KU-32 both bind to the C-terminal domain of Hsp90, but surprisingly, KU-32 stimulated the chaperone functions of Hsp90 via allosteric modulation of its N-terminal domain, responsible for the chaperone's ATPase activity. In vitro and in silico studies indicated that upon KU-32 binding, Hsp90 undergoes global structural changes leading to the formation of a "partially closed" intermediate that selectively binds ATP and increases ATPase activity. We also report that KU-32 promotes HeLa cell survival and enhances the refolding of an Hsp90 substrate inside the cell. This discovery explains the effectiveness of KU-32 analogs in the management of neuropathies and may facilitate the design of molecules that promote cell survival by enhancing Hsp90 chaperone function and reducing the load of misfolded proteins in cells.

RESUMO

BACKGROUND: There is now a rising commitment to acknowledge the role patients and families play in contributing to their safety. This review focuses on one type of involvement in safety - patient and family involvement in escalation of care for serious life-threatening conditions i.e. helping secure a step-up to urgent or emergency care - which has been receiving increasing policy and practice attention. This review was concerned with the negotiation work that patient and family members undertake across the emergency care escalation pathway, once contact has been made with healthcare staff. It includes interventions aiming to improve detection of symptoms, communication of concerns and staff response to these concerns. OBJECTIVES: To assess the effects of interventions designed to increase patient and family involvement in escalation of care for acute life-threatening illness on patient and family outcomes, treatment outcomes, clinical outcomes, patient and family experience and adverse events. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL, MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP) ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform from 1 Jan 2000 to 24 August 2018. The search was updated on 21 October 2019. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and cluster-randomised controlled trials where the intervention focused on patients and families working with healthcare professionals to ensure care received for acute deterioration was timely and appropriate. A key criterion was to include an interactive element of rehearsal, role play, modelling, shared language, group work etc. to the intervention to help patients and families have agency in the process of escalation of care. The interventions included components such as enabling patients and families to detect changes in patients' conditions and to speak up about these changes to staff. We also included studies where the intervention included a component targeted at enabling staff response. DATA COLLECTION AND ANALYSIS: Seven of the eight authors were involved in screening; two review authors independently extracted data and assessed the risk of bias of included studies, with any disagreements resolved by discussion to reach consensus. Primary outcomes included patient and family outcomes, treatment outcomes, clinical outcomes, patient and family experience and adverse events. Our advisory group (four users and four providers) ensured that the review was of relevance and could inform policy and practice. MAIN RESULTS: We included nine studies involving 436,684 patients and family members and one ongoing study. The published studies focused on patients with specific conditions such as coronary artery disease, ischaemic stroke, and asthma, as well as pregnant women, inpatients on medical surgical wards, older adults and high-risk patients with a history of poor self-management. While all studies tested interventions versus usual care, for four studies the usual care group also received educational or information strategies. Seven of the interventions involved face-to-face, interactional education/coaching sessions aimed at patients/families while two provided multi-component education programmes which included components targeted at staff as well as patients/families. All of the interventions included: (1) an educational component about the acute condition and preparedness for future events such as stroke or change in fetal movements: (2) an engagement element (self-monitoring, action plans); while two additionally focused on shared language or communication skills. We had concerns about risk of bias for all but one of the included studies in respect of one or more criteria, particularly regarding blinding of participants and personnel. Our confidence in results regarding the effectiveness of interventions was moderate to low. Low-certainty evidence suggests that there may be moderate improvement in patients' knowledge of acute life-threatening conditions, danger signs, appropriate care-seeking responses, and preparedness capacity between interactional patient-facing interventions and multi-component programmes and usual care at 12 months (MD 4.20, 95% CI 2.44 to 5.97, 2 studies, 687 participants). Four studies in total assessed knowledge (3,086 participants) but we were unable to include two other studies in the pooled analysis due to differences in the way outcome measures were reported. One found no improvement in knowledge but higher symptom preparedness at 12 months. The other study found an improvement in patients' knowledge about symptoms and appropriate care-seeking responses in the intervention group at 18 months compared with usual care. Low-certainty evidence from two studies, each using a different measure, meant that we were unable to determine the effects of patient-based interventions on self-efficacy. Self-efficacy was higher in the intervention group in one study but there was no difference in the other compared with usual care. We are uncertain whether interactional patient-facing and multi-component programmes improve time from the start of patient symptoms to treatment due to low-certainty evidence for this outcome. We were unable to combine the data due to differences in outcome measures. Three studies found that arrival times or prehospital delay time was no different between groups. One found that delay time was shorter in the intervention group. Moderate-certainty evidence suggests that multi-component interventions probably have little or no impact on mortality rates. Only one study on a pregnant population was eligible for inclusion in the review, which found no difference between groups in rates of stillbirth. In terms of unintended events, we found that interactional patient-facing interventions to increase patient and family involvement in escalation of care probably have few adverse effects on patient's anxiety levels (moderate-certainty evidence). None of the studies measured or reported patient and family perceptions of involvement in escalation of care or patient and family experience of patient care. Reported outcomes related to healthcare professionals were also not reported in any studies. AUTHORS' CONCLUSIONS: Our review identified that interactional patient-facing interventions and multi-component programmes (including staff) to increase patient and family involvement in escalation of care for acute life-threatening illness may improve patient and family knowledge about danger signs and care-seeking responses, and probably have few adverse effects on patient's anxiety levels when compared to usual care. Multi-component interventions probably have little impact on mortality rates. Further high-quality trials are required using multi-component interventions and a focus on relational elements of care. Cognitive and behavioural outcomes should be included at patient and staff level.

RESUMO

Objectives. To examine measurement comparability of a Spanish version of self-rated health (SRH) with pasable as an alternative to regular for the response category "fair" in the English version.Methods. We translated "fair" into 2 Spanish versions: regular and pasable. We implemented a split-half experiment in 3 surveys independently conducted from October 2015 to January 2016, from April to November 2016, and from August to November 2017. Within each survey, we randomly assigned Spanish-interviewed Latino respondents to 1 of the 2 SRH versions. The total sample included 3261 Latino and 738 non-Latino White adults in the United States.Results. Spanish-interviewed Latinos reported substantively more favorable health on SRH with pasable than with regular. When pasable instead of regular was used for SRH, we observed a larger difference between respondents reporting positive versus negative SRH on objective health measures, including the frequency of doctor's visits. Furthermore, when we accounted for correlates of health, Latino-White disparities were attenuated with pasable.Conclusions. We recommend using pasable instead of regular for SRH Spanish translations to improve measurement equivalence in cross-lingual and cross-cultural research.

RESUMO

The development of C-terminal heat shock protein 90 kDa (Hsp90) inhibitors has emerged as a potential treatment for cancer. Similarly, small molecules that target the mitochondria have proven to be efficacious towards cancer, as the reprogramming of mitochondrial function is often associated with oncogenic transformation. Herein, we report the development of triphenylphosphonium (TPP)-conjugated Hsp90 C-terminal inhibitors, their anti-proliferative activity, and accumulation in the mitochondria. In general, TPP-conjugated Hsp90 C-terminal inhibitors were found to manifest increased activity against various cancer cell lines when compared to the parent compounds.

RESUMO

BACKGROUND: Through its influence on social interactions, simpatía may have a wide-ranging influence on Latinx health. Simpatía-which does not have a direct English translation-refers to being perceived as likeable, pleasant, and easygoing. Research to investigate the influence simpatía on Latinx health is limited, likely due to a lack of options for measuring simpatía among diverse Latinx populations. OBJECTIVES: The goal of this research was to develop a bilingual, survey-based simpatía scale for use among ethnically diverse Latinx adults in health-related settings. METHODS: Data were obtained through a telephone survey data of 1,296 Mexican American, Puerto Rican, and Cuban American adults living in the United States. Interviews were conducted in English and Spanish. Exploratory factor analysis, item response theory analysis, confirmatory factor analysis, and computation of estimates of internal consistency reliability were conducted to inform the development of the final simpatía scale. RESULTS: Results indicate that the final, nine-item, simpatía scale has high internal consistency (α = .83) and measurement invariance among Mexican American, Puerto Rican, and Cuban American adults. Two dimensions were identified, as indicated by a perceptions subscale and a behavior subscale. Cuban Americans were found to have the highest simpatía scores, followed by Puerto Ricans and Mexican Americans. DISCUSSION: Culture is often identified as a powerful potential influence on health-related behaviors, but measures are often not available to assess specific cultural traits. By developing a new tool for measuring simpatía, this research advances opportunities for understanding and promoting Latinx health.

RESUMO

Research indicates that Latino survey respondents are more likely to acquiesce than non-Latino European Americans, thereby decreasing the potential for measurement invariance across cultural groups. In order to better understand what drives this culturally patterned response style, we examined the influence of respondent and interviewer characteristics on acquiescence. Data were obtained from a telephone survey of 400 Mexican American, Puerto Rican, Cuban American, and non-Latino European American respondents and a self-administered survey of 21 interviewers. Higher acquiescence was associated with several respondent characteristics: older age, lower education, stronger Latino cultural orientation, Spanish use, Latino ethnicity, and, among Latinos, Cuban American ethnicity. In contrast, acquiescence was not influenced by respondent-interviewer social distance, social deference, or interviewer characteristics (e.g., education, gender, acculturation, interviewer experience). These findings indicate that acquiescence differs across Latino ethnic subgroups and that respondent and language factors are more influential determinants of acquiescence than survey interviewers.

RESUMO

Personalismo may have a broad influence on the well-being of U.S. Latinos by shaping social networks, and, in turn, access to information and resources. However, research on personalismo is currently constrained by the lack of a psychometrically sound measure of this cultural construct. This research used a mixed methods approach to develop a personalismo scale across three studies: a cognitive interviewing study with Mexican American adults (n=33); a cognitive interviewing study with non-Latino white, Mexican American, Puerto Rican, and Cuban American adults (n=61); and a psychometric telephone survey with Mexican American, Puerto Rican, and Cuban American adults (n=1,296). The final, 12-item scale had high internal consistency reliability and appears to be appropriate for use with Mexican American, Puerto Rican, and Cuban American adults. Significant differences emerged across Latino subgroups, with higher personalismo observed among Cuban Americans and female respondents, providing empirical evidence of cultural heterogeneity among U.S. Latino populations.

RESUMO

This study described experiences of caregivers of persons with Alzheimer's disease and other dementias (ADRD) and caregivers of persons with other chronic conditions on self-reported health, type of assistance they provide, perceptions of how caregiving interferes with their lives, and perceived level of support. A secondary analysis was conducted of the 2013 Porter Novelli SummerStyles survey data. Of the 4033 respondents, 650 adults self-identified as caregivers with 11.6% caring for people with ADRD. Over half of all caregivers reported that caregiving interfered with their lives to some extent. The greater the perceived support caregivers reported, the less they thought that caregiving interfered with their lives (p < .001). No significant differences were found between ADRD and non-ADRD caregivers regarding general health, types of assistance they provided, and perceived level of support. These findings have the potential to inform future research and practice in the development of supportive services for caregivers.

RESUMO

Inhibition of the Hsp90 C-terminus is an attractive therapeutic approach for the treatment of cancer. Novobiocin, the first Hsp90 C-terminal inhibitor identified, contains a synthetically complex noviose sugar that has limited the generation of structure-activity relationships for this region of the molecule. The work described herein utilizes various ring systems as noviose surrogates to explore the size and nature of the surrounding binding pocket.

RESUMO

Based on a theoretical framework describing culturally sensitive (CS) health communication, this experiment tested the relative contributions of surface structure and deep structure in the recall of oral health information from pamphlets varied in written message and images. Using a 2 × 2 factorial design, Spanish-speaking Mexican heritage mothers of children under six (n = 160) were randomly assigned to read one of four 12-page pamphlets containing the same oral health information in Spanish: (1) standard written message/standard images; (2) standard written message/CS images; (3) CS written message/standard images; and (4) CS written message/CS images. Participants completed a 22-item oral health knowledge questionnaire before and after reading the pamphlet. Controlling for the effects of pretest scores, acculturation, and educational level on information recall, findings showed significant positive main effects for CS images (F(1, 152) = 5.03, p = .026, partial ŋ2 = .032) and CS written message (F(1, 152) = 5.21, p = .024, partial ŋ2 = .033). There was no interaction. These results support the two dimensions of CS and their independent effects. They should be applicable to a variety of health communication channels. Further research is needed to investigate the causal mechanism behind the observed effects.

RESUMO

Additional research is needed to guide the design of narratives for use in practice-oriented, naturalistic settings to maximize health behavior change, particularly among populations affected by health disparities. This mixed-methods study explored the influence of cultural tailoring and emotional arousal on identification and message recall in narratives promoting childhood obesity prevention among 40 Mexican American mothers. Participants were also asked about narrative exposure, narrative preferences, and beliefs about the purpose of a story. Participants were randomly assigned to listen to two stories: (a) a story tailored on noncultural or cultural variables, and (b) a story designed to enhance or minimize emotional arousal. Participants reported high engagement and identification with all stories. Participants generally envisioned protagonists as Latina, despite limited cues, and identified with protagonists in four ways: sharing personal characteristics; having similar thoughts and feelings; engaging in similar actions; and experiencing similar situations. Mothers were most interested in narratives that helped them to improve their lives. Findings from this study yield several hypotheses for consideration in future study, including ways in which story setting and message enactment may moderate message recall.
