RESUMO

This manuscript details the strategy employed for categorising food items based on their processing levels into the four NOVA groups. Semi-quantitative food frequency questionnaires (FFQs) from the Nurses' Health Studies (NHS) I and II, the Health Professionals Follow-up Study (HPFS) and the Growing Up Today Studies (GUTS) I and II cohorts were used. The four-stage approach included: (i) the creation of a complete food list from the FFQs; (ii) assignment of food items to a NOVA group by three researchers; (iii) checking for consensus in categorisation and shortlisting discordant food items; (iv) discussions with experts and use of additional resources (research dieticians, cohort-specific documents, online grocery store scans) to guide the final categorisation of the short-listed items. At stage 1, 205 and 315 food items were compiled from the NHS and HPFS, and the GUTS FFQs, respectively. Over 70 % of food items from all cohorts were assigned to a NOVA group after stage 2. The remainder were shortlisted for further discussion (stage 3). After two rounds of reviews at stage 4, 95⋅6 % of food items (NHS + HPFS) and 90⋅7 % items (GUTS) were categorised. The remaining products were assigned to a non-ultra-processed food group (primary categorisation) and flagged for sensitivity analyses at which point they would be categorised as ultra-processed. Of all items in the food lists, 36⋅1 % in the NHS and HPFS cohorts and 43⋅5 % in the GUTS cohorts were identified as ultra-processed. Future work is needed to validate this approach. Documentation and discussions of alternative approaches for categorisation are encouraged.

RESUMO

The literature on body image and food consumption has generally focused on isolated food items, while overlooking the growing role of ultra-processed foods in the overall diet. The objective of this study was to assess the association of body image (dis)satisfaction and perception with food consumption, according to the NOVA classification, which takes into account the extent and purpose of industrial food processing. A silhouette scale developed considering the Brazilian adults' Body Mass Index was used to assess body image (dis)satisfaction and perception. Food consumption was evaluated using a Food Frequency Questionnaire, and its items were categorized into three groups: unprocessed or minimally-processed foods and culinary preparations; processed foods; ultra-processed foods. The association was assessed using linear regression models. A total of 514 of Brazilian university employees were evaluated. Women dissatisfied due to excess weight consumed less unprocessed or minimally-processed foods and culinary preparations (-6.6, 95% CI: -10.7; -2.5) and more ultra-processed foods (3.7, 95% CI: 0.1; 7.2) compared to satisfied. Women that overestimated their body size consumed less unprocessed or minimally-processed food and culinary preparations (-4.2, 95% CI: -7.3; -1.1), compared to those who had not distorted body image. Food consumption appears to be more strongly associated with body image (dis)satisfaction than with perception. An association was established between body image dissatisfaction and unhealthy eating habits. This relation deserves public health attention since it may contribute to the development of chronic diseases and reduce the quality of life and body image assessment could be adopted by nutritionists and other health professionals in their practice.

RESUMO

Nutrient profiling systems (NPS) are used around the world. In some countries, the food industry participates in the design of these systems. We aimed to compare the ability of various NPS to identify processed and ultra-processed Mexican products containing excessive amounts of critical nutrients. A sample of 2544 foods and beverages available in the Mexican market were classified as compliant and non-compliant according to seven NPS: the Pan American Health Organization (PAHO) model, which served as our reference, the Nutrient Profiling Scoring Criterion (NPSC), the Mexican Committee of Nutrition Experts (MCNE), the Health Star Rating (HSR), the Mexican Nutritional Seal (MNS), the Chilean Warning Octagons (CWO) 2016, 2018 and 2019 criteria, and Ecuador's Multiple Traffic Light (MTL). Overall, the proportion of foods classified as compliant by the HSR, MTL and MCNE models was similar to the PAHO model. In contrast, the NPSC, the MNS and the CWO-2016 classified a higher amount of foods as compliant. Larger differences between NPS classification were observed across food categories. Results support the notion that models developed with the involvement of food manufacturers are more permissive than those based on scientific evidence. Results highlight the importance of thoroughly evaluating the underlying criteria of a model.

RESUMO

The objective of the study was to estimate the contribution of ultra-processed foods to total caloric intake and investigate whether it differs according to socioeconomic position. We analyzed baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil 2008-2010; N = 14.378) and data on dietary intake using a food frequency questionnaire, assigning it into three categories: unprocessed or minimally processed foods and processed culinary ingredients, processed foods, and ultra-processed foods. We measured the associations between socioeconomic position (education, per capita household income, and occupational social class) and the percentage of caloric contribution of ultra-processed foods, using generalized linear regression models adjusted for age and sex. Unprocessed or minimally processed foods and processed culinary ingredients contributed to 65.7% of the total caloric intake, followed by ultra-processed foods (22.7%). After adjustments, the percentage of caloric contribution of ultra-processed foods was 20% lower among participants with incomplete elementary school when compared to postgraduates. Compared to individuals from upper income classes, the caloric contribution of ultra-processed foods was 10%, 15% and 20% lower among the ones from the three lowest income, respectively. The caloric contribution of ultra-processed foods was also 7%, 12%, 12%, and 17% lower among participants in the lowest occupational social class compared to those from high social classes. Results suggest that the caloric contribution of ultra-processed foods is higher among individuals from high socioeconomic positions with a dose-response relationship for the associations.

RESUMO

The aim of this cross-sectional study was to investigate the association between sedentary behavior and consumption of ultra-processed foods (UPF) among Brazilian adolescents. The study used data from the 2015 edition of the Brazilian National School Health Survey (PeNSE). Daily consumption of at least one group of UPF was the outcome, and the principal exposure was daily time spent in sedentary behavior (hours spent sitting, except for time sitting at school). We calculated prevalence rates, prevalence ratios, and 95% confidence intervals (95%CI). The analyses were adjusted for gender, age, skin color, maternal schooling, household assets index, major geographic region, and school's administrative jurisdiction (public versus private). Forty percent of the schoolchildren reported daily consumption of at least one group of UPF (39.7%; 95%CI: 39.2-40.3), while 68.1% (95%CI: 67.7-68.7) reported > 2 hours/day of sedentary behavior. Among schoolchildren with sedentary behavior > 2 hours/day, prevalence of daily consumption of UPF was 42.8% (95%CI: 42.1-43.6%), higher than among those without sedentary behavior (29.8%; 95%CI: 29.0-30.5%). Longer time spent in sedentary behavior was associated with higher prevalence of consumption of UPF (p-value for linear trend < 0.001). Strategies to promote healthy eating and decrease sedentary behavior, as well as regulation of advertising for UPF, are necessary to prevent unhealthy lifestyles from persisting into adulthood.

Foram utilizados dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) realizada em 2015. O consumo diário de pelo menos um grupo de AUP representou o desfecho, e a exposição principal foi o tempo diário de comportamento sedentário (horas em atividades sentado, excluído o tempo dispendido na escola). Foram calculadas prevalências, razões de prevalências e intervalos de 95% de confiança (IC95%). As análises foram ajustadas para sexo, idade, cor da pele, escolaridade materna, índice de bens, região geográfica e dependência administrativa da escola. Cerca de 40% dos escolares reportaram consumo diário de pelo menos um grupo de AUP (39,7%; IC95%: 39,2-40,3) e 68,1% (IC95%: 67,7-68,7) referiram > 2 horas/dia de comportamento sedentário. Entre os escolares com comportamento sedentário > 2 horas/dia, a prevalência de consumo diário de AUP foi de 42,8% (IC95%: 42,1-43,6%), maior do que entre os sem comportamento sedentário (29,8%; IC95%: 29,0-30,5%). Quanto maior o tempo de comportamento sedentário, maior a prevalência de consumo de AUP (valor de p para tendência linear < 0,001). Estratégias que promovam a alimentação saudável e a diminuição de comportamentos sedentários, bem como regulamentações da publicidade de AUP, tornam-se necessárias a fim de evitar que estilos de vida não saudáveis perdurem à idade adulta.

O estudo teve como objetivo estimar a contribuição dos alimentos ultraprocessados à ingestão calórica total e investigar se essa contribuição difere de acordo com nível socioeconômico. Analisamos os dados da linha de base do Estudo Longitudinal de Saúde do Adulto-Brasil (ELSA-Brasil 2008-2010; N = 14.378) e os de ingestão alimentar, usando um questionário sobre frequência de consumo alimentar, em três categorias: alimentos não processados ou minimamente processados e ingredientes culinários processados, alimentos processados e alimentos ultraprocessados. Estimamos as associações entre nível socioeconômico (escolaridade, renda domiciliar per capita e classe social ocupacional) e o percentual da contribuição calórica dos ultraprocessados, usando modelos lineares generalizados, ajustados por idade e sexo. Os alimentos não processados ou minimamente processados e ingredientes culinários processados representaram 65,7% da ingestão calórica total, seguidos pelos ultraprocessados (22,7%). Depois dos ajustes, a contribuição dos ultraprocessados foi 20% mais baixa entre participantes com ensino fundamental incompleto, quando comparados aos indivíduos com pós-graduação. Quando comparados aos indivíduos das classes de renda mais alta, a contribuição calórica dos ultraprocessados foi 10%, 15% e 20% mais baixa entre aqueles pertencentes aos três quintis de renda mais baixos, respectivamente. Além disso, a contribuição calórica dos ultraprocessados foi 7%, 12%, 12% e 17% mais baixa entre os participantes da classe social ocupacional mais baixa, comparados aos das classes sociais mais altas. Os resultados sugerem que a contribuição calórica dos alimentos ultraprocessados é mais alta entre os indivíduos de nível socioeconômico mais alto, com gradiente de dose e resposta nas associações.

El objetivo del estudio fue estimar la contribución de las comidas ultraprocesadas en la ingesta total calórica e investigar si difiere según el nivel socioeconómico. Analizamos datos de referencia, procedentes del Estudio Longitudinal Brasileño sobre Salud en la Edad Adulta (ELSA-Brasil 2008-2010; N = 14.378) y datos de la ingesta nutricional, usando un cuestionario de frecuencia sobre comidas, asignándole tres categorías: comida sin procesar o mínimamente procesada e ingredientes culinarios procesados, comidas procesadas, y comidas ultraprocesadas. Medimos las asociaciones entre el nivel socioeconómico (educación, ingreso por hogar per cápita, y clase ocupacional social) y el porcentaje de la contribución calórica de la comida ultraprocesada, usando modelos de regresión lineal generalizada, ajustados por edad y sexo. Las comidas sin procesar o mínimamente procesadas con ingredientes culinarios procesados contribuyeron al 65,7% del total de la ingesta calórica, seguidos de la comida ultraprocesada (22,7%). Tras los ajustes, el porcentaje de la contribución calórica de la comida ultraprocesada fue un 20% menor entre los participantes con la escuela elemental incompleta, cuando se compararon con los postgraduados. Comparados con los individuos de las clases con ingresos superiores, la contribución calórica de las comidas ultraprocesadas fue un 10%, 15% y 20% menor entre quienes pertenecían a las tres categorías de ingresos más bajas, respectivamente. La contribución calórica de la comida ultraprocesada fue también un 7%, 12%, 12%, y 17% más baja entre los participantes en el nivel ocupacional social más bajo, comparados con aquellos de las clases sociales altas. Los resultados sugieren que la contribución calórica de la comida ultraprocesada es más alta entre quienes proceden de niveles socioeconómicos más altos con una relación dosis-respuesta para las asociaciones establecidas.

RESUMO

OBJECTIVE: To establish temporal trends in household food and drink consumption in Brazil, taking into account the extent and purpose of its industrial processing. METHODS: Data was obtained from Household Budget Surveys conducted in Brazil in 1987-1988, 1995-1996, 2002-2003 and 2008-2009. In all surveys, probabilistic samples of households in the metropolitan areas were studied and, for the last two surveys, the scope was national. The units of analysis were food purchases records of clusters of households. The purchased food items were divided according to the extent and purpose of their industrial processing into: 'in natura' or minimally processed foods, processed culinary ingredients and ready-to-consume, processed and ultra-processed food and drink products. The quantity of each item was converted into energy. For each survey, the daily availability of calories per capita and the caloric share of the food groups were estimated. For the national surveys, estimates were calculated by income quintiles. Temporal trends were assessed using linear regression models and difference of means tests. RESULTS: The caloric share of ready-to-consume products significantly increased between 2002-2003 and 2008-2009 (from 23.0% to 27.8% of total calories), mainly because of the increase in the consumption of ultra-processed products (20.8% to 25.4%). In the same period, there was a significant reduction in the caloric share of foods and culinary ingredients. The increase in the ultra-processed products caloric share occurred across all income quintiles. There was an uniform increase in the caloric share of ready-to-consume products in the metropolitan areas, mostly in place of ultra-processed products, accompanied by a decrease in the share of 'in natura' or minimally processed foods and culinary ingredients. CONCLUSIONS: The share of ultra-processed products significantly increased in the Brazilian diet, as seen in the metropolitan areas since the 1980s, and confirmed at a national level in the 2000s.

RESUMO

Eating outside of the home environment on a frequent basis has been associated with weight gain. Food choices when eating out are usually high in energy content, which contributes to excessive energy intake; however, the available data on out-of-home eating and obesity are far from conclusive. This systematic review assesses the association between out-of-home eating and body weight in adults over 18 years of age. The literature databases searched included Medline, Embase, Lilacs, The Cochrane Library, and the ISI Web of Knowledge. The review includes a comprehensive quality assessment of all included observational studies, 20 cross-sectional studies, and 8 prospective cohort studies. All but one of the prospective cohort studies and about half of the cross-sectional analyses found a positive association between out-of-home eating and body weight. However, many methodological differences among the studies were found, such as the definition of out-of-home eating and its assessment, which limits comparisons. The results of the present analysis suggest that in future studies fast-food restaurants and other out-of-home dining venues should be analyzed separately, assessments based on a single 24-h recall should be avoided, and controls for at-home choices (which were not included in any of the studies reviewed) are necessary to evaluate this association.

RESUMO

BACKGROUND: Chronic diseases are the leading cause of premature death and disability in the world with overnutrition a primary cause of diet-related ill health. Excess energy intake, saturated fat, sugar, and salt derived from processed foods are a major cause of disease burden. Our objective is to compare the nutritional composition of processed foods between countries, between food companies, and over time. DESIGN: Surveys of processed foods will be done in each participating country using a standardized methodology. Information on the nutrient composition for each product will be sought either through direct chemical analysis, from the product label, or from the manufacturer. Foods will be categorized into 14 groups and 45 categories for the primary analyses which will compare mean levels of nutrients at baseline and over time. Initial commitments to collaboration have been obtained from 21 countries. CONCLUSIONS: This collaborative approach to the collation and sharing of data will enable objective and transparent tracking of processed food composition around the world. The information collected will support government and food industry efforts to improve the nutrient composition of processed foods around the world.
