Eating egg-rich diets and modeling the addition of one daily egg reduced the risk of nutrient inadequacy among U.S. adolescents with and without food insecurity.

BACKGROUND: Adolescents have the poorest dietary intakes throughout the lifespan. Food insecurity worsens these nutritional risks. Eggs are one nutrient-dense strategy to increase nutrient quality. OBJECTIVE: 1) compare usual nutrient intakes, Dietary Reference Intakes and protein compliance with recommendations, and scores of micronutrient quality; and 2) analyze how adding one egg affects adolescents' nutrient profiles, by food security status and egg-rich diets. METHODS: Dietary data of U.S. adolescents in the 2007-2018 NHANES were analyzed (14-17 years; n=3,633). Egg-rich diet levels were categorized 1) non-eggs, 2) eggs as ingredients in dishes, or 3) primarily egg dishes. Food security status was classified using the U.S. Household Food Security Survey Module. The National Cancer Institute method was used to estimate usual nutrient intake and nutrient exposure scores (i.e., food nutrient index and total nutrient index). Nutrient amounts from one medium egg were modeled on existing intakes. Pairwise t-tests determined significant differences. RESULTS: Over 60% of adolescents risked inadequate intake of calcium, choline, magnesium, and vitamins D and E regardless of food security status. Food secure adolescents consuming primarily egg dishes had higher mean usual intakes of lutein + zeaxanthin (1544.1 mcg), choline (408.4 mg), vitamin B2 (2.3 mg), selenium (128.6 mcg), vitamin D (6 mcg), docosahexaenoic acid (70 mg), and protein (89.1g) than other groups (P<0.0002). Those consuming eggs as ingredients in dishes demonstrated higher nutrient adequacy, for magnesium (scored ∼66 out of 100), potassium (scored 81), and total scores (scored 72 and 69, respectively) for the TNI and FNI; and folate only (scored 92) for the TNI, than those not consuming eggs (P<0.0002). Adding one egg increased choline and vitamin D usual intakes for some groups and nutrient index scores for all groups (P<0.0005). CONCLUSIONS: Adolescents are at substantial nutritional risk that was exacerbated by food insecurity and less egg consumption.

Unhealthy food advertising on Costa Rican and Guatemalan television: a comparative study.

This study aimed to exhaustively explore the characteristics of food advertising on TV in Guatemala and Costa Rica. The International Network for Food and Obesity Non-Communicable Diseases (NCDs) Research, Monitoring and Action Support (INFORMAS) methodology was applied. In 2016, we recorded 1440 h of video among 10 TV channels. We used the Pan American Health Organization (PAHO) Nutrient Profile (NP) Model to identify 'critical nutrients', whose excessive consumption is associated with NCDs. We created a nutritional quality score (0 if the product did not exceed any critical nutrient, 1 if the product exceeded one and 2 if it exceeded ≥2). We classified food ads as permitted (score = 0) and not-permitted (score 1 or 2) for marketing. Persuasive marketing techniques were classified as promotional characters (e.g. Batman), premium offers (e.g. toys), brand benefit claims (e.g. tasty) and health-related claims (e.g. nutritious). In Guatemala, foods that exceeded one critical nutrient were more likely to use persuasive marketing techniques, and in Costa Rica were those with an excess of ≥2 critical nutrients, compared with foods without any excess in critical nutrients [Guatemala: promotional characters (odds ratio, OR = 16.6, 95% confidence interval, CI: 5.8, 47.3), premium offers (OR = 3.4, 95% CI: 1.4, 8.2) and health-related claims (OR = 3.5, 95% CI: 2.2, 5.7); Costa Rica: health-related claims (OR = 4.2, 95% CI: 2.0, 8.5)]. In conclusion, Guatemalan and Costa Rican children are exposed to an overabundance of not-permitted food ads on TV. This justifies implementing national policies to reduce exposure to not-permitted food for marketing, including on TV and other media.

This study aimed to exhaustively explore the characteristics of food advertising on TV in Guatemala and Costa Rica. In 2016, we recorded 1440 h of video among 10 TV channels. We used the PAHO Nutrient Profile Model to identify 'critical nutrients' (e.g. sodium) whose excessive consumption is associated with Non-Communicable Chronic Diseases (e.g. hypertension). We created a nutritional quality score (0 if the product did not exceed any critical nutrient, 1 if the product exceeded one and 2 if it exceeded ≥2). We classified food ads as permitted (score = 0) and not-permitted (score 1 or 2) for marketing. Persuasive marketing techniques were classified as promotional characters, premium offers, brand benefit claims and health-related claims. In Guatemala, foods that exceeded one critical nutrient had a high probability of using promotional characters, premium offers and health-related claims than foods without any excess in critical nutrients. However, in Costa Rica health-related claims had a high probability of appearing with foods that exceeded ≥2 critical nutrients. In conclusion, Guatemalan and Costa Rican children are exposed to an overabundance of not-permitted food ads on TV. This justifies implementing national policies to reduce exposure to not-permitted food for marketing.

Overabundance of unhealthy food advertising targeted to children on Guatemalan television.

To assess, for the first time, the extent (by hour channel) and nature (e.g. persuasive marketing techniques (PMT) and health-related claims) of unhealthy food advertisements (ads) targeted at children (3-11 years) on the six most-watched television (TV) channels in Guatemala. We recorded 864 h of video on the six most popular channels featuring children's programmes. We classified food and beverage ads as permitted or non-permitted for marketing to children, according to the 2015 World Health Organisation (WHO) nutrient profile. Furthermore, we also analysed PMT (i.e. premium offers, promotional characters, brand benefit claims) and health-related claims. Most food ads (85%) were non-permitted to be marketed to children. Non-permitted food ads were six times more likely, either on weekdays or weekends, for all programme and channel categories compared with permitted food ads. There was no difference in the frequency of non-permitted food ads between peak and non-peak hours, weekend and weekdays or children and non-children programmes. PMT and health-related claims were present in all food ads (5.3 ± 1.9 techniques/claims per ad). There is a need to regulate food ads on TV channels featuring children's programmes in Guatemala as a result of a high frequency of non-permitted food ads and extensive use of PMT together with health-related claims.

Efficacy of front-of-pack warning label system versus guideline for daily amount on healthfulness perception, purchase intention and objective understanding of nutrient content of food products in Guatemala: a cross-over cluster randomized controlled experiment.

BACKGROUND: Front-of-package warning labels (FOPWL) have been adopted in many countries aiming at reducing the consumption of unhealthy food and drink products and have also been considered in Guatemala. The aim of the study is to evaluate the efficacy of FOPWL versus Guidelines for Daily Amount (GDA) on products' healthfulness perception (HP), purchase intention (PI) and the objective understanding of the nutrient content (UNC) in Guatemala. METHODS: Participants (children and adults) (n = 356) were randomly assigned to evaluate either FOPWL or GDA during a crossover cluster randomized experiment in rural and urban areas across 3 phases of exposure. During phase 1, participants evaluated mock-up images of single products (single task) and compared pairs of products within the same food category (comparison task) without any label. In phase 2, participants evaluated labels only (without any product), and during phase 3, they evaluated the same products and questions from phase 1, now depicting the assigned front-of-package label. We generated indicators for single-task questions and scores for comparison tasks, one for each HP, PI and UNC questions. We used intention-to-treat, difference-in-difference regression analysis to test whether exposure to FOPWL was associated with HP, PI and UNC, compared to GDA. We also tested models for children and adults and by area (rural/urban) separately adjusting for sociodemographic variables. RESULTS: In single tasks, FOPWL significantly decreased the PI (ß -18.1, 95%CI -23.3, -12.8; p < 0.001) and the HP (ß -13.2, 95%CI -18.4, -7.9; p < 0.001) of unhealthy food products compared to GDA. In the comparison task, FOPWL significantly increased the UNC (ß 20.4, 95%CI 17.0, 23.9; p < 0.001), improved PI towards healthier choices (OR 4.5, 95%CI 2.9, 7.0 p < 0.001) and HP (OR 5.6, 95%CI 2.8, 11.1; p < 0.001) compared to GDA. Similar results were found in children and adults and in urban and rural settings. CONCLUSIONS: FOPWL reduces products' healthfulness perception and purchase intention, and increases understanding of products' nutrient content compared to GDA.
