The individual-level effects of social media campaigns related to healthy eating, physical activity, and healthy weight: A narrative review.

Objective: Social media are promising channels for health communication promoting positive weight-related behaviors, but no prior studies have synthesized evidence on the independent effects of social media campaigns focused on promoting healthy eating, physical activity (PA), and healthy weight. This study aimed to fill that gap and inform future social media-based obesity-prevention research and practice by reviewing findings from studies testing the effects of such campaigns on individual-level cognitive, behavioral, and anthropometric outcomes. Method: The Web of Science and PubMed databases were searched for peer-reviewed articles published between 2012 and 2023 that explored the independent effects of social media campaigns related to healthy eating, PA, or weight management. Study characteristics and outcomes were extracted and summarized. Results: Eleven studies were included in this review describing campaigns targeting healthy eating-related outcomes (e.g., fruit and vegetable consumption, meal preparation, nutrition label reading), PA, or weight management. Most campaigns (n = 7) were developed by universities or research centers. Priority audiences included parents, adult females, adolescents, college students, and adult government employees. The majority (n = 8) of the campaigns used single platforms, with the most common being Facebook, Instagram, blogs, and YouTube. Campaigns had mixed effects on cognitive outcomes (e.g., intention, attitude, knowledge), behavioral outcomes (e.g., food choices, PA), and anthropometric outcomes (e.g., weight, waist circumference). Conclusion: Social media campaigns focused on promoting healthy eating, PA, and healthy weight had mixed effects on individual-level cognitive, behavioral, and anthropometric outcomes. Various limitations of the included studies make it difficult to ascertain which factors influence campaign effectiveness. Advancing knowledge in this area is important, particularly given social media's widespread use and potential for broad reach. New research with features such as rigorous study designs, larger and more diverse samples, and strong theoretical foundations may provide important insights into what types of interventions are effective or not and under what conditions.

Effectiveness of Theory-Based Physical Activity and Nutrition Interventions in Aging Latino Adults: A Scoping Review.

In the United States (US), Latino individuals older than 50 years face health disparities compared to their White counterparts. Considering the rising life expectancy and the projected increase of older Latino adults in the US, this scoping review aimed to determine the effectiveness of theory-based and culturally relevant strategies that promote healthy aging in Latinos. Web of Science and PubMed databases were searched between December 2022 and February 2023 for peer-reviewed articles assessing healthy aging interventions tailored to community-dwelling aging Latino adults. We included nine studies describing the effects of seven interventions on physical activity- or nutrition-related outcomes. Although not always statistically significant, interventions had a beneficial impact on well-being indicators. The most commonly used behavioral theories were Social Cognitive Theory and Attribution Theory. Latino cultural elements in these studies included partnering with community organizations that serve Latinos (such as Catholic churches), delivery of in-person bilingual group sessions by trusted community members (such as promotoras or Latino dance instructors), and incorporating values such as family and religion into the health curriculum, among others. Future strategies that promote healthy aging in Latino adults should proactively culturally adapt the theoretical foundations and the design, recruitment, and implementation processes to ensure their relevance and effectiveness.

Perceived intrinsic, social, and environmental barriers for weight management in older Hispanic/Latino adults with obesity.

Background: The burden of obesity and chronic disease is increasing in the older US Hispanic/Latino adult population. There is limited evidence on successful weight management strategies as perceived by this population. Assessing barriers and opportunities for weight management using mixed methods is a robust approach to collect in-depth information that can be applied to the development of well-tailored weight management interventions for this population. Objective: The objective of this study was to assess perceived individual, interpersonal, and environmental factors that influence weight management in older Hispanic/Latino adults. Methods: This community-based cross-sectional study included 23 Hispanic/Latino older (>50y) adults with obesity (BMI >30 kg/m2). Perceived barriers and opportunities for weight management were assessed through validated questionnaires and focus groups. Prospectively registered on ClinicalTrials.gov (NCT03978416) on 7 June 2019. Results: In this demographically heterogeneous population, language acculturation was generally low, and the frequency of poor dietary behaviors was high. Participants linked financial strain to lower diet quality, as well as anxiety to uncontrolled eating and food cravings. Social support and trust in healthcare professionals were perceived as priorities for healthy eating. Structural and environmental barriers such as affordability and availability of culturally preferred foods were also identified as influences on food choices and eating behavior. Conclusions: This study revealed opportunities for culturally tailored weight management interventions in older Hispanic/Latino adults with obesity. Clinical Trial Registry Number: NCT03978416 (ClinicalTrials.gov).

Lessons learned by adapting and implementing LUCHA: a deep-structure culturally tailored healthy eating randomized pilot intervention for ethnic-diverse Latinos.

Objectives: To report the adaptation and implementation of LUCHA (Latinos United for a Culturally Healthy Alimentation), a pilot intervention to improve dietary quality and behaviors (primary outcomes) of Latinos in Massachusetts, US, and the lessons learned during the process, including disruptions during the COVID-19 pandemic, to help shape future programs. Methods: The cultural adaptation process was pre-planned using a framework, grounded in the Theory of Reasoned Action/Planned Behavior, and informed by formative mixed-methods research. A projected 75 self-identifying Latino adults (25-65y) were recruited with community-wide strategies and randomized to receive, in parallel, daily healthy eating text messages for 2 months, reinforced for 2 subsequent months, to either control (i.e., surface-level messages based on USDA MyPlate in Spanish), or intervention (i.e., deep-structure messages). The intervention messages were ethnically tailored to Caribbean or non-Caribbean heritages specifically, grounded in entrenched cultural attitudes, norms, and preferences. Trained research assistants administered questionnaires and clinical measurements at baseline, 2-months, and 4-months, in person (pre-pandemic) or via online video calls (at-pandemic). Clinicaltrials.gov registration #NCT04724382. Results: LUCHA faced challenges and opportunities that conveyed lessons for future cultural adaptation and implementation of healthy eating programs. Recommendations are provided to improve digital programs for diverse ethnicities, such as widening language capabilities in texting services, using familiar video call applications, and instructing participants to measure their own clinical metrics at home using guided standardized protocols. Conclusion: Tailoring nutrition programs with deep-structure cultural messages is essential when promoting healthy eating in diverse Latino heritages. LUCHA can inform programs for similar ethnic groups.

Cultural Adaptation and Social Media Promotion of Healthy Eating Guides for Spanish Speakers.

OBJECTIVE: The internet is a primary source of nutrition information in the US. Minorities and non-English speakers face a digital divide when accessing such information. We aimed to report on the reach of social media dissemination of the cultural adaptation of the evidence-based Kid's Healthy Eating Plate to Spanish-speaking Latinos and of previous versions. METHODS: The adaptation was based on the Framework for Reporting Adaptations and Modifications-Expanded and was disseminated through social media platforms (116 days). Outcomes were impressions, shares, website link clicks, number of viewers, and access country. RESULTS: The kids' culturally adapted version had 288,773 impressions and 1,227 shares on social media; the website was linked 9,763 times, predominantly through Facebook (Meta Platforms, Inc). User engagement and pageviews were mostly from Spain, Latin American countries, and the US. CONCLUSIONS AND IMPLICATIONS: The cultural adaptation of healthy eating guidelines for Spanish-speaking children was accessed in the US and worldwide. Promotion through social media had a significant impact on its reach. Cultural adaptation and paid dissemination of evidence-based materials may help close the digital divide and promote health literacy in diverse populations.

Effect of six different cooking techniques in the nutritional composition of two fish species previously selected as optimal for renal patient's diet.

Benefits of fish consumption are widely known, but there is little information about nutrient values of raw and cooked fish. The aim was to study the impact that six cooking techniques have on the nutritional composition of two fish species with low content of adverse nutrients in renal diet. Raw and steamed, foiled with aluminum, foiled with banana leaf, gas oven-baked, microwave oven-coked and fried lightly samples were chemically analyzed to determine their protein, phosphorus and lipid content. Crevalle jack: all methods increased lipid and protein content and fatty acids (FA) varied in all cooking methods. Phosphorus decreased in the steamed and microwave oven-cooked samples. Red drum: foiled and fried lightly increased lipid content compared to the raw sample. FA concentration changed in all cooking methods. Protein increased with every technique and phosphorus decreased in the steamed and gas oven-baked samples. Renal patients should preferably consume crevalle jack steamed or microwave oven-cooked and red drum steamed or gas oven-baked.

[Fatty acid variation in yellowfin tuna, spotted weakfish and Florida pompano when submitted to six cooking techniques]. / Variación del contenido de lípidos y perfil de acidos grasos en atún, trucha marina y pámpano sometidos a seis técnicas de cocción.

The aim of the present study was to analyze the effect of six cooking techniques (steamed, foiled, foiled with banana leaf, baked, microwave-cooked and light frying) in the fatty acid content of Thunnus albacore (yellowfin tuna), Cynoscionnebulosus (spotted weakfish) and Trachinotuscarolinus (Florida pompano). After cooking the fish fillets, fatty acid analyses were performed using gas chromatography. Total lipids increased in all cooking techniques in tunaand spotted weakfish. Saturated fatty acids of tuna and spotted weakfish increased in three cooking techniques, while in Florida pompano only gas oven raised their content. Lightly frying generated the highest content of n-3 in tuna and spotted weakfish, and the lowest in Florida pompano, specie that presented less variation. In tuna fish, the most recommended cooking techniques are foiled with aluminum and microwave oven; for spotted weakfish, foiled with banana leaf; while Florida pompano can be prepared using all cooking methods except gas oven. This information is useful to enrich data from chemical composition tables, in which concentrations are usually presented in raw food.
