RESUMEN

OBJECTIVES: The self-administered version of the Mediterranean Diet Scale (MDS) has been developed to test the inherent characteristics of this dietary pattern in a quick and simple way, due to the need of this assessment in the clinical and research setting. This study aimed to translate and psychometrically validate the self-administered MDS in Arabic (CRBS-A). METHODS: The original (English) version was originally translated to Arabic, followed by back-translation. Next, 10 healthcare providers, followed by 10 cardiovascular disease (CVD) patients rated the face and content validity (CV) of materials, providing input to improve cross-cultural applicability. Then, 200 patients from Saudi Arabia completed the questionnaire, of which factor structure, internal consistency, criterion and construct validity were assessed. RESULTS: Content and face validity was supported based on experts and patients' reviews (ranges: CV scores 0.9-1.0/1.0 and clarity 3.5 to 4.5/5). Minor edits were made. Subsequent factor analysis revealed 4 factors consistent with the original version of the instrument, all internally consistent. Total CRBS-A α was 0.74. Criterion validity was confirmed by the significantly higher scores in patients who participated in CR. Construct validity was also established by significant associations between MDS scores and monthly family income, having the diagnosis of acute coronary syndrome or with a history of valve repair or replacement, being obese or having dyslipidemia. CONCLUSIONS: Overall, these results confirm the validity and reliability of the MDS in Arabic-speaking patients.

RESUMEN

In Brazil, any advertising strategies that take advantage of the child's judgment or induce consumers to make harmful health choices are considered abusive. However, the efficacy of restrictions on their use on television (TV) food advertising remains poorly understood. This study analysed the extent and nature of abusive techniques according to national regulations and patterns in their use in food-related ads. Cross-sectional studyrecorded the programming of the three most popular TV channels (6 am-12 am), during eight non-consecutive days, in April 2018. Data collection was based on the INFORMAS protocol and two national regulations. Descriptive analyses were used to describe the types of food ads and abusive techniques used in ultra-processed products (UPP) ads. Principal component analysis was applied to identify patterns of abusive marketing techniques and to relate them to specific food groups. More than 90% of food ads included at least one UPP. Overall, 10.1% of UPP ads targeted children and 57.7% used some kind of abusive technique directed to children and adolescents. Most ads contained messages inducing harmful health choices did not present adequate and clear information about the product and contained more than one type of abusive technique. Four out of five patterns in the use of abusive techniques in UPP ads were specifically directed to children, and fast-food meals were associated with three out of five patterns. The high abusiveness of food advertising in UPP ads should be considered a public health concern given their impact on children's food choices and health.

RESUMEN

Abstract Objective Movies and TV programs directed to children contain food information that can potentially negative influence their food consumption. The NOVA classification is a useful system for monitoring food informational environment. Therefore, this study aimed to evaluate food content on children movies using the NOVA classification. Methods The 13 top box office children movies released from 2013 to 2018 were evaluated. Each food reference was classified as unprocessed or minimally processed, processed and ultra-processed food (UPF) and as positive, negative, and neutral message transmitted. Results One hundred and ninety-eight (n = 198) scenes that contained 555 food references were included. The frequency of references to unprocessed and minimally processed foods (60.1%) was similar to references of UPF (59.1%). Fruit/vegetables and sweets represented 37.9% of food appearances each. Scenes containing fruit/vegetables conveyed more negative (62.5%) or neutral messages (49.3%) than positive (26.4%). UPF scenes contained more positive (70.9%) and negative content (75.0%) than neutral (37.3%). Regarding UPF subcategories, sweets scenes were more positive (49.1%) than neutral (22.4%) and fast food meals scenes were more negative (37.5%) than neutral (5.9%). Conclusions UPF, unprocessed food, and minimally processed foods have similar frequency in the movies. Except for fast food meals, UPF were commonly more associated with positive situations and unprocessed and minimally processed foods were more commonly associated with negative contexts.

RESUMEN

The consumer food environment is changing: an extensive variety of foods are now available in most markets, offering palatability, convenience and novelty. However, little is known about the availability and advertising of food items within food outlets, especially among developing countries. The present study examined these dimensions in 281 food outlets located around eighteen primary healthcare services in Belo Horizonte, Brazil, in 2013. These establishments were classified as large-chain supermarkets; specialised fruits and vegetable (F&V) markets; and local grocery stores, convenience stores or bakeries. Availability of F&V, availability of ultra-processed foods (UPF) and food advertising were compared across the food outlet categories by applying the χ2 test. Almost 60 % of the food outlets were specialised F&V markets, 21⋅4 % were large-chain supermarkets and 19⋅2 % were local grocery stores, convenience stores or bakeries. Almost 80 % contained at least eight types of fruits and vegetables, and 60 % contained UPF. Food advertisement was absent in 59⋅8 % of the food outlets, 19⋅6 % were advertising only F&V and 17⋅4 % were advertising only UPF. Higher F&V availability was noted inside specialised F&V markets and large-chain supermarkets than local grocery stores, convenience stores or bakeries. Advertising of F&V was more common within specialised F&V markets. However, large-chain supermarkets and local grocery stores, convenience stores or bakeries contained more frequent UPF food advertising isolated: 38⋅3 and 35⋅2 %, respectively. Therefore, the availability and advertising of food items within food outlets around primary healthcare services are different according to the type of food outlet.

RESUMEN

OBJECTIVES: This study investigated the use of persuasive advertising strategies in ultra-processed food (UPF) advertisements broadcast on the three most popular free-to-air television channels in Brazil. METHODS: The programming of the selected channels was recorded on eight non-consecutive days from April 2018 (6:00 am-12:00 am). Information from each advertising piece was collected through an electronic questionnaire based on the INFORMAS protocol. Food products were classified according to the NOVA classification system. Marketing strategies were investigated in UPF advertisements and stratified into three groups. Principal component analysis was used to identify patterns of strategies. Linear regression models were employed to investigate the association between the patterns and food groups. RESULTS: In total, 90.77% of the food-related advertisements contained at least one UPF, and 96% of them included one or more persuasive advertising strategies. Five advertising patterns were identified and associated with the UPF food groups. CONCLUSIONS: The results showed that food advertising on Brazilian free television is marked by UPF, with the predominant use of persuasive advertising strategies, demonstrating a lack of enforcement of the current regulatory legislation in the country.

RESUMEN

Abstract Objective: To compare the participation of food groups - fresh and minimally processed, processed, and ultra-processed - in the diet of students (n = 1357) from Belo Horizonte, MG, Brazil, in accordance with the number of school meals consumed daily. Methods: Four groups were defined: children that did not consume school meals and children that consumed one, two, or three school meals daily. Food groups participation, in g/1000 kcal, was obtained using two 24-hour recalls. Three linear regression models were analyzed, in which the consumption of each of the food groups was the dependent variable, the number of school meals was the independent variable, and sociodemographic data (gender, age, health vulnerability) and overweight condition were the control variables. Results: Children that consumed 2 or 3 school meals daily showed, respectively, 7.3% and 10.5% higher ingestion of fresh and minimally processed food in comparison to children that did not consume school meals. Moreover, ultra-processed food participation was 18.0% lower among students that consumed two school meals and 26.0% lower among children that consumed three meals daily, in comparison to students that did not consume school meals. Conclusion: The study showed a possible dose-response effect in children's daily diets with two or three school meals and highlighted the relevance of the prolonged stay at school for healthy eating promotion in children.


Resumo Objetivo: Comparar a participação dos alimentos in natura e minimamente processados, processados e ultraprocessados na alimentação de 1.357 escolares de Belo Horizonte (MG) de acordo com o número de refeições escolares consumidas diariamente. Métodos: Foram definidos quatro grupos de estudo: crianças que não consumiam a alimentação escolar e crianças que consumiam uma, duas ou três refeições escolares diariamente. A participação na dieta dos grupos de alimentos, em g/1.000 kcal, foi obtida a partir de dois recordatórios alimentares de 24 horas. Foram analisados três modelos de regressão linear, nos quais o consumo de cada um dos três grupos de alimentos constituiu a variável dependente, o número de refeições escolares consumidas diariamente constituiu a variável independente e os dados sociodemográficos (sexo, idade, índice de vulnerabilidade à saúde) e de excesso de peso constituíram-se as variáveis de ajuste. Resultados: Verificou-se que as crianças que consumiam duas e três refeições escolares diariamente apresentaram, respectivamente, 7,3% e 10,5% maior ingestão de alimentos in natura e minimamente processados quando comparadas com as crianças que não consumiam a alimentação escolar. Além disso, a participação de ultraprocessados foi 18,0% menor na alimentação das crianças que consumiam duas refeições escolares e 26,0% menor entre as que consumiam três refeições escolares diariamente, em comparação com aquelas que não consumiam a alimentação escolar. Conclusão: O estudo apontou possível efeito dose-resposta na proteção da alimentação dos estudantes a partir do consumo de duas refeições escolares diárias, destacando a relevância da permanência da criança em período integral na escola para a promoção da alimentação saudável.

RESUMEN

OBJECTIVE: To analyse the content and extent of marketing of ultra-processed food products (UPP) and their brand pages on Facebook, which are highly accessed by Brazilians. DESIGN: Descriptive. SETTING: Sixteen UPP brand pages on Facebook were selected from 250 pages that were the most liked by Brazilians in October 2015. SUBJECTS: We analysed the frequency of 'likes' and members 'talking about' each one of the pages, in addition to fifteen marketing techniques used in the previous year (September 2014 to October 2015). The number of posts, likes, 'shares' and 'commentaries', and the mean number of likes, shares and commentaries per post, were collected for one month, from 23 September to 23 October 2015. RESULTS: The two most liked pages were: Coke® (93 673 979 likes) and McDonald's® (59 749 819 likes). Regarding the number of people talking about the pages, McDonald's led with 555 891 commentaries, followed by Coke (287 274), Burger King® (246 148) and Kibon® (244 523). All pages used marketing techniques, which included photos, user conversations, presence of brand elements and links. Videos were observed on 93·8 % of the pages; promotions on 68·8 %; and celebrities on 62·5 %. In one month, Garoto®, Outback® and Coke were brands that published more than one post per day. Kibon achieved the highest ratio of likes per post (285 845·50) and Burger King had the highest mean shares per post (10 083·93), including commentaries per post (7958·13). CONCLUSIONS: UPP marketing is extensively used on Facebook pages and is highly accessed by Brazilians, with UPP companies employing a diversity of marketing strategies.

RESUMEN

OBJECTIVE: To analyze the occurrence of anemia and iron deficiency in children aged 1 to 5 years and the association of these events and retinol deficiency. METHODS: This was an observational analytic cross-sectional study conducted in Vitoria, ES, Brazil, between April and August of 2008, with healthy children aged 1 to 5 years (n = 692) that lived in areas covered by primary healthcare services. Sociodemographic and economic conditions, dietary intake (energy, protein, iron, and vitamin A ingestion), anthropometric data (body mass index-for-age and height-for-age), and biochemical parameters (ferritin, hemoglobin, and retinol serum) were collected. RESULTS: The prevalence of anemia, iron deficiency, and retinol deficiency was 15.7%, 28.1%, and 24.7%, respectively. Univariate analysis showed a higher prevalence of anemia (PR: 4.62, 95% CI: 3.36, 6.34, p < 0.001) and iron deficiency (PR: 4.51, 95% CI: 3.30, 6.17, p < 0.001) among children with retinol deficiency. The same results were obtained after adjusting for socioeconomic and demographic conditions, dietary intake, and anthropometric variables. There was a positive association between ferritin vs. retinol serum (r = 0.597; p < 0.001) and hemoglobin vs. retinol serum (r = 0.770; p < 0.001). CONCLUSIONS: Anemia and iron deficiency were associated with low levels of serum retinol in children aged 1 to 5 years, and a positive correlation was verified between serum retinol and serum ferritin and hemoglobin levels. These results indicate the importance of initiatives encouraging the development of new treatments and further research regarding retinol deficiency. .


OBJETIVO: Analisar a ocorrência de anemia e de deficiência de ferro em crianças de 1 a 5 anos e a associação destes desfechos com a deficiência de retinol. MÉTODOS: Trata-se de um estudo observacional analítico do tipo transversal, realizado no município de Vitória - ES, entre abril e agosto de 2008, com crianças (n = 692) saudáveis de 1 a 5 anos, residentes em áreas de abrangência de Unidades Básicas de Saúde. Foram avaliados dados sociodemográficos, econômicos, dietéticos (ingestão de energia, proteína, ferro e vitamina A), antropométricos (índice de massa corporal-por-idade e estatura-por-idade) e bioquímicos (níveis séricos de ferritina, hemoglobina e retinol). RESULTADOS: Detectou-se anemia, deficiência de ferro e deficiência de retinol em 15,7%, 28,1% e 24,7% das crianças, respectivamente. A análise univariada evidenciou maior ocorrência de anemia (RP: 4,62; IC 95%: 3,36; 6,34, p < 0.001) e de deficiência de ferro (RP: 4,51; IC 95%: 3,30; 6,17, p < 0.001) entre crianças que apresentavam deficiência de retinol. As mesmas relações se mantiveram após o ajuste pelas variáveis socioeconômicas, demográficas, dietéticas e antropométricas. Houve relação positiva entre os valores de ferritina sérica vs. retinol (r = 0,597; p < 0,001) e hemoglobina vs. retinol (r = 0,770; p < 0,001). CONCLUSÕES: A anemia e a deficiência de ferro mostraram-se associadas com baixos níveis de retinol em crianças de 1 a 5 anos, e houve correlação positiva dos níveis de retinol com os de ferritina sérica e hemoglobina. Isto torna importante iniciativas que estimulem o desenvolvimento de novos tratamentos e a ampliação de pesquisas em relação à deficiência ...
